Description

  The present invention relates to a temperature adjusting element and a temperature adjusting device for vehicles, particularly electric vehicles or hybrid vehicles.

  In the case of electric vehicles, combustion waste heat cannot be used to heat the cabin. Electrical resistance heating requires a significant increase in battery capacity, which is generally very expensive. Accordingly, there is a need for alternative heating and cooling methods to reduce the demand for electrical energy to maintain passenger comfort.

  With respect to electric vehicles, PTC auxiliary heaters or posistor auxiliary heaters are possible measures to cover passenger cabin heating demand in the cold season when not accompanied by fuel such as gasoline, bioethanol or the like. PTC auxiliary heaters located on the air side have already been mass-produced for cold start of vehicles with little intermittent waste heat, for example modern diesel vehicles. One realization is here, for example, according to the principle of a heating element, in which layers of fins are superposed and glued together and PTC pellets are provided between them. This design eliminates the need for a frame, housing, tube, etc. that surrounds the heating element or parts of the heating element, and is reliably bonded to each adjacent layer by a material bond through an adhesive bond. It is particularly easy to do. However, in this simple construction mode, the fins themselves are electrically conductive, so this construction mode is only suitable for low voltage applications, such as 12V vehicle power system.

  Another method is to realize a heating element using Peltier technology. In this connection, for example, heating element prototypes with alternative cooling functions to support AC circuits have already been presented. However, in the case of these prototypes, the structural principle seems to be relatively expensive and three-dimensional, for example, a large depth is required. The Peltier effect of thermoelectric materials is already used for cooling in niche applications, for example for cooling electronic components and in camping cool boxes. While the efficiency of automobile applications has been considered to be too low so far, in the exhaust pipe of a vehicle driven by an internal combustion engine, the reverse effect of generating electricity based on the temperature difference by the thermoelectric system, Famous by famous manufacturers in the professional industry, it will develop towards the start of mass production. Until now, conventional refrigeration circuits have been used for air conditioning of cabins, and electric heaters have been widely trusted for heating in first-generation electric vehicles.

  In the case of purely electrical heating, high quality electrical energy is converted into low quality thermal energy. This is a conflict between two considerations. First, in order to provide a storage capacity using, for example, a lithium ion battery, about 500 to 700 euros / kWh is required. In the technology using Peltier elements that has been considered in the past, it is quite complicated to electrically couple alternately doped p-type and n-type chips in an electrical series connection. Higher costs are required to realize than when heated by. In addition, the electrical insulator generally has thermal insulation properties, and deteriorates heat transfer. When the driving temperature gradient is large, the thermoelectric system is more greatly affected by COP or efficiency reduction than the conventional heat pump. The resistance heater simply achieves COP = 1 and significantly impairs the cruising range of the electric vehicle. The freezing circuit in principle operates with acceptable COPs, but includes many individual components and must be replenished with refrigerant periodically. As a whole, a unit for heating (heating body) and a unit for cooling (refrigeration circuit) must be separately prepared for each of the two functions.

  The object of the present invention is to propose an improved temperature regulating element and an improved temperature regulating device.

This problem is solved by the temperature adjusting element according to claims 1 and 2 and the temperature adjusting device according to claim 10 .

  The recognition underlying the present invention is that the heating element or the cooling element is made into a layer structure by devising the series connection of the Peltier elements so that the Peltier elements doped in the same shape are adjacent to each other and arranged in layers. It can be realized.

  The difference between using PTC pellets when using Peltier elements is that, inter alia, two differently doped materials, ie p-type and n-type doped materials, are bonded together. is there. Typically, the configuration formed by Peltier elements is such that the high temperature side of two atypically doped Peltier elements and the low temperature side of the two atypically doped Peltier elements are conductively connected. This configuration results in a series connection as a whole. However, this type of configuration is almost impossible to apply directly to a heating or cooling body suitable for manufacturing. This is because the metal conductor does not form a continuous bridge that spans between two adjacent doped elements that are directly adjacent. The interrupted portion can only be crosslinked by a non-conductor. This non-conductor is an obstacle to heat transfer on both sides.

  The heating element described in the method according to the invention has a cooling function capable of heating or cooling the cabin of an electric vehicle, and as much as possible with as little cost as possible and already available manufacturing techniques. It can be produced at low cost and has high efficiency by optimizing heat transfer.

  The heating body according to the invention can have an easily manufacturable uninterrupted bridge for fins and an uninterrupted passage for cooling water, each of which is implemented as a conductor. Has been. High heat transfer can be achieved by thermally coupling the Peltier element to the liquid side and / or the air side as directly as possible. The reason why this can be realized is considered to be that an electrical insulator as a thermal barrier is not present in this region. Advantageously, this kind of combination of series and parallel connections can be adapted to 12V. Heat transfer to the air-side fins and cooling water passages can in one embodiment be performed on two sides. Furthermore, this type of structure offers the advantage that the thermal insulation effect of galvanic separation can be realized without any problems, for example, since there is no temperature gradient between the fins due to symmetry conditions. In general, the significant advantage is that the difference between a heating element manufactured according to existing manufacturing methods, for example a heating element with a PTC auxiliary heater, is as small as possible while at the same time providing optimal heat transfer. It is only a point. Therefore, optimum efficiency or COP (coefficient of performance) is obtained. As a result, the basic structure designed in accordance with the method according to the present invention is substantially different in two respects from the basic structure of a heated body using bonding by material bonding. First of all, the cooling water passage already exists as a heat source for heating operation or as a heat sink for cooling operation. Second, there is an electrical insulating layer in the center between the corrugated fins. Therefore, the operating mode of the heating element according to the present invention having a Peltier element for heating operation or cooling operation is configured such that the overall net heat flow occurs only in the vertical direction and is interpreted as such. Is done.

  Advantageously, heating with COP> 1 without combustion waste heat is possible, and the functions of cooling and heating can be integrated into one structure. Furthermore, the refrigerant becomes unnecessary, and it becomes easy to perform dispersion by repeatedly arranging the layers by modularity and further repeating the surface structure in one layer.

  The present invention proposes a temperature regulating element for a vehicle, the temperature regulating element for inducing the following features: a first Peltier element layer, a second Peltier element layer, a first heat transfer fluid A first conductive heat conductor layer; and a second conductive heat conductor layer for inducing a second heat transfer fluid, wherein the first Peltier element layer and the second Peltier element A layer, the first thermal conductor layer and the second thermal conductor layer are arranged in the form of a laminate, whereby the first thermal conductor layer and / or the second thermal conductor A layer is disposed between the first Peltier element layer and the second Peltier element layer, and a current induced in the stack is based on the Peltier effect. Temperature adjustment of the heat conductor layer and the second heat conductor layer is performed.

  The temperature adjusting element can be used, for example, in an electric vehicle or a hybrid vehicle, and thereby the temperature of the passenger compartment of the vehicle can be adjusted. In this case, temperature adjustment can mean both heating and cooling. The first Peltier element layer and the second Peltier element layer can be formed of two differently doped semiconductor materials. Thus, for example, the first Peltier element layer is doped n-type and the second Peltier element layer is doped p-type, or conversely, the first Peltier element layer is p-type. The second Peltier element layer can be doped n-type. For the Peltier element layer, other suitable conductors can be used in place of the semiconductor material. The first and second conductive heat conductor layers can be formed of a metal having good conductivity. The current applied to the temperature adjustment element can flow into the temperature adjustment element from one end of the laminate, and after flowing through the entire laminate, for example, through a suitable contact connected to the wire, The laminate can exit again from one end on the opposite side. A heat conduction fluid can flow through each of the first and second conductive heat conductor layers. The first and second heat conductor layers are arranged in the stack so that the temperature generated by the Peltier effect can be transferred to the heat transfer fluid guided in the stack. It can arrange | position with respect to a Peltier device layer. According to the Peltier effect and the arrangement of the heat conductor layer with respect to the Peltier element layer, one of the heat transfer fluids is always heated and the other is cooled during operation of the temperature adjusting element. The first and second heat transfer fluids may be, for example, a gas or a liquid, respectively. In this case, depending on the role that the temperature control element should play, it can be used to guide one of the heat transfer fluids into the passenger compartment of the vehicle, thereby cooling or heating the passenger compartment. Can do. When the current flow in the temperature adjusting element is reversed, the heat transfer fluid heated by the temperature adjusting element can be cooled. The reverse is also true. In order to prevent leakage current through the heat transfer fluid, it is possible to place an electrical insulating part between the heat transfer fluid and the surface of the heat transfer layer facing the heat transfer fluid. is there.

  In one embodiment, the temperature adjustment element may include a further first conductive heat conductor layer, and additionally or alternatively, a further second conductive heat conductor layer. Can be included. In this case, the further first and / or the second further heat conductor layer may be formed by the first or the second by means of at least one of the first or the second Peltier element layer. It can be separated from the heat conductor layer and placed in the laminate. For example, in the configuration of the stacked body, the second thermal conductor layer is present at the bottom of the stacked body, and the first Peltier element layer is disposed on the thermal conductor layer. It can be configured as shown. Further, the first thermal conductor layer can be disposed on the first Peltier element layer, and the second Peltier element layer is present on the first thermal conductor layer. To do. The second thermal conductor layer forms a terminal portion of the temperature adjustment element stack. Alternatively, the laminate may be configured such that the further first thermal conductor layer forms the first layer of the laminate. On the still another first thermal conductor layer, for example, the first Peltier element layer, the second thermal conductor layer, the first thermal conductor layer, and the second Peltier element layer Further, the second heat conductor layers can be arranged one after another, and in this case, a heat insulating layer is provided between the second heat conductor layer and the first heat conductor layer. Can be arranged.

  When the temperature control element includes a further second conductive heat conductor layer, the second heat conductor layer can have a first electrical contact, and the further second heat conduction layer. The body layer can have a second electrical contact. In this case, the first Peltier element layer and the second Peltier element layer may be disposed between the second thermal conductor layer and the further second thermal conductor layer. Is possible. The first thermal conductor layer can be disposed between the first Peltier element layer and the second Peltier element layer. In this arrangement, a first Peltier effect can be realized in the first thermal conductor layer, whereby the first thermal conductor layer is made to have a polarity of current induced in the stack. Depending on, it can be heated or cooled. According to another Peltier effect opposite to the first Peltier effect, the second heat conductor layer can be heated when the first heat conductor layer is cooled, or The second thermal conductor layer can be cooled when the first thermal conductor layer is heated. This arrangement does not require a thermal insulating layer between the individual layers, and has the further advantage that the thermally conductive layers, which are always temperature-controlled to be different, are always separated by the Peltier element layer. Provide. Further, when another temperature adjustment element of the same type is stacked on the temperature adjustment element, only galvanic separation is required between the two temperature adjustment elements, and thermal galvanic separation is unnecessary. This is because here, two thermal conductor layers are arranged adjacent to each other, and these thermal conductor layers have the same temperature by undergoing the same Peltier effect.

  Alternatively, the temperature adjustment element can further include a further first heat conductor layer and a further second heat conductor layer. The first thermal conductor layer can have a first electrical contact, and the further first thermal conductor layer can have a second electrical contact. Further, the temperature adjusting element may have an electric wire for connecting the second heat conductor layer to the further second heat conductor layer. In this case, the first thermal conductor layer and the second thermal conductor layer can be disposed between the first Peltier element layer and the second Peltier element layer, The first Peltier element layer and the second Peltier element layer are disposed between the further first thermal conductor layer and the further second thermal conductor layer. Is possible. Further, a galvanic / thermal insulating layer may be disposed between the first thermal conductor layer and the second thermal conductor layer. In this arrangement, current flows from the first electrical contact into the temperature regulating element, from there through the second Peltier element layer, the second thermal conductor layer, and further via an electric wire to the further It passes through another second thermal conductor layer, the first Peltier element layer, and finally passes through the further first thermal conductor layer. The current can be derived from the temperature adjustment element at the second electrical contact, and in some cases can be induced into another temperature adjustment element.

  In yet another embodiment, the various thermal conductor layers of the temperature adjusting element can be connected to each other via additional wires. In this case, each of the additional electric wires can be disposed at an end portion of the thermal conductor layer of the temperature adjusting element on the side opposite to the electric wires. Accordingly, the thermal conductor layer with the first or second contact can each have an additional contact for connecting the additional wire. For example, the current supply line and the transmission line are mounted on the left and right sides of the temperature adjustment element in this manner using cables, so that the current strength in the bridges or fins of the various thermal conductor layers of the temperature adjustment element is increased. It is possible to assist in reducing the height. Thereby, since the connection is only on one side, the strength of the current at the inflow portion to the heat conductor layer becomes the strength of the total of all the currents passing through the Peltier element layer in a row, The drawback of sometimes unacceptable current density can be eliminated.

  The first Peltier element layer has at least two first Peltier element conductors disposed adjacent to each other, and the second Peltier element layer is disposed adjacent to each other. It has a second Peltier element conductor. The distance between the individual Peltier elements can be selected according to the heat output of the Peltier element conductor. An electric insulating part can be disposed between the individual Peltier element conductors. According to the area of the Peltier element layer, a corresponding number of Peltier element conductors can be arranged adjacent to each other. In this case, the Peltier element conductors can be arranged in a plane, that is, for example, side by side in both the longitudinal direction and the lateral direction.

  In an alternative embodiment, the first Peltier element layer and the second Peltier element layer each have at least one first Peltier element conductor and at least one second Peltier element conductor. it can. In this case, it is possible to arrange the first and second Peltier element conductors adjacent to each other so as to be conductively connected to each other. Accordingly, the current induced in the laminate can continuously flow through the first Peltier element conductor and the second Peltier element conductor. For example, the first Peltier element conductor can be doped n-type and the second Peltier element conductor can be doped p-type, or vice versa. This embodiment of the temperature adjusting element offers the advantage that the already existing prototype heating element can be used as the basis of the Peltier technology for the assembly of the temperature adjusting element proposed here. This saves time and costs in production.

  In one embodiment, the first heat conductor layer can be configured as a coolant passage, and the second heat conductor layer can be configured as a fin member. For example, the coolant passage can be configured as a pipe for guiding the coolant. The fin member may be composed of, for example, two bridges, and a metal band bent in a zigzag shape or a wave shape is disposed between the bridges, for example, between the bridges. Fins arranged obliquely are formed. The second heat transfer fluid may be, for example, air, which is guided from around the vehicle into the vehicle and guided through the second heat conductor layer, where the second heat transfer fluid is It is cooled or heated to match the temperature of the heat conductor layer. Such a structure of the second thermal conductor layer advantageously provides a large temperature conducting surface for the fluid guided in the second thermal conductor layer. Of course, the first heat conductor layer can be configured to guide air, and the second heat conductor layer can be configured to guide liquid. Similarly, the first thermal conductor layer may have a plurality of adjacent coolant passages, and the second thermal conductor layer is positioned adjacent to each other. It can have a fin member.

  The first thermal conductor layer may have a galvanic insulating layer on the outer surface. The galvanic insulating layer can be surrounded by a conductor layer, and the conductor layer is configured to allow a current to flow between the first Peltier element layer and the second Peltier element layer. It is possible to keep. For example, the first heat conductor layer may be entirely surrounded by the conductor layer, or the conductor layer may be attached to two opposite side surfaces of the first heat conductor layer to the electric wire. Can be connected. In this way, it can be ensured that the current flow passes through the laminate of the temperature regulating elements, and at the same time, the first thermal conductor layer is also excluded from the current flow. Has been. Therefore, it is possible to avoid a leakage current from entering the coolant flowing through the first thermal conductor layer.

  The first heat conductor layer and the second heat conductor layer are configured to realize orthogonal flow directions with respect to the first heat conduction fluid and the second heat conduction fluid. It is possible to leave. By doing in this way, the inflow part and outflow part of the said different heat conduction fluid can be arrange | positioned on the different side surface of the said temperature control element.

  The present invention further proposes a temperature regulating device comprising a plurality of temperature regulating elements, wherein the plurality of temperature regulating elements are coupled in series connection via the respective first and second contacts. ing.

  In one embodiment, a galvanic insulating layer may be disposed between each two of the plurality of temperature adjustment elements. In this way, it can be guaranteed that the current flow passes through all the temperature adjusting elements of the temperature adjusting device one after another. It is possible to connect the respective contacts of the first and last temperature adjustment mechanisms relating to the current flow to a current source. Furthermore, the galvanic insulating layer disposed between the adjacent temperature adjusting elements can be used as a thermal insulating portion between the individual temperature adjusting elements. This is particularly important when two heat conductor layers that are temperature-adjusted differently are arranged adjacent to each other in the temperature-adjusting device. The temperature adjusting elements can be connected in series, in parallel, or in a mixed form in the temperature adjusting device.

  The plurality of temperature adjusting elements can be arranged in at least one stacked body. In this case, the dimensions of the temperature adjustment device can be determined by stacking a corresponding number of temperature adjustment elements and / or by extending the individual layers of the plurality of temperature adjustment elements in a horizontal direction. It can be adapted to various spatial circumstances. Of course, the temperature adjusting device may be formed of a plurality of laminated bodies, and these laminated bodies are arranged so as to be adjacent to each other, and the respective contacts are connected in series connection or parallel connection. Are connected through.

Temperature control equipment for a vehicle as a reference example, the following features, namely, first the first heat conductor layer for inducing heat transfer fluid, a plurality of Peltier elements are arranged separately A Peltier element layer having a plurality of Peltier elements including a conductor, and a second heat conductor layer for inducing a second heat conduction fluid, wherein the layers are laminated bodies. Thus, the Peltier element layer is arranged between the first thermal conductor layer and the second thermal conductor layer. The Peltier element layer operates to cool the first thermal conductor layer and to heat the second thermal conductor layer or vice versa during operation of the temperature control device. Can be configured. Each Peltier element can be designed as an individual Peltier module. This means that each Peltier element has its own electrical connection for supplying and delivering current flowing through the Peltier element conductor of the Peltier element. Each of the Peltier elements has a substrate, on which only the Peltier element conductors of the respective Peltier elements are arranged. The distance between adjacent Peltier element conductors in the Peltier element can be smaller than the distance between adjacent Peltier elements. Each of the Peltier elements can have both an n-type doped Peltier element conductor and a p-type doped Peltier element conductor. The Peltier element conductor may be mounted as a vapor-deposited conductive path or as a fabric.

  The plurality of Peltier elements of the Peltier element layer can cover a maximum of 1/10 of the total area of the Peltier element layer. A thermally insulated intermediate space can be provided between the Peltier elements. Alternatively, the plurality of Peltier element conductors can cover a maximum of 1/10 of the total area of the Peltier element layer.

The temperature regulating device, there in another Peltier element layer is al, a plurality of still another Peltier element, respectively include a plurality of still another Peltier element conductor which Peltier elements are arranged separately A further Peltier element layer and a further second heat conductor layer for inducing the second heat transfer fluid. In this case, the further Peltier element layer can be disposed between the first thermal conductor layer and the further second thermal conductor layer in the stacked body. In this way, thermal insulation is not necessary between adjacent layers.

Alternatively, the temperature adjustment device may have a thermal insulation layer, a further second heat conductor layer for inducing the second heat transfer fluid, and a further Peltier element layer. The further Peltier element layer has a plurality of further Peltier layers (600), the Peltier elements being spaced apart from each other and each including a plurality of further Peltier element conductors. In this case, the thermal insulation layer is disposed adjacent to the previous second thermal conductor layer in the laminate, and the further second thermal conductor layer is disposed in the laminate in the thermal structure. It is possible to arrange between an insulating layer and the further Peltier element layer.

When the temperature adjusting device has a switching mechanism, the switching mechanism first operation and the second in the mode heat conductor layer and yet another the of the temperature adjusting device said second heat transfer fluid The second heat conductor layer and the further second heat conductor layer so as to guide the second heat conductor layer and in the second operation mode of the temperature adjusting device, It is comprised so that it may guide in either one. The temperature adjusting element can be configured as a flap. The temperature adjusting device can achieve a larger heat output in the first operation mode than in the second operation mode. Advantageously, the active Peltier element conductor is capable of flowing a current having an optimum current intensity for operating the Peltier element conductor in both the first operating mode and the second operating mode. is there.

For example , the adjacent Peltier element layers, for example, the first Peltier element layer and the second Peltier element layer may have different numbers of Peltier element conductors or Peltier elements. Alternatively or additionally, the arrangement of Peltier element conductors or Peltier elements in adjacently arranged Peltier element layers may be different. Alternatively or additionally, the extending areas of the Peltier element conductors or Peltier elements in the adjacent Peltier element layers may be different. The temperature distribution in the Peltier element layer can be adjusted by appropriately selecting the arrangement, number and / or size. In particular, it is possible to realize a uniform temperature distribution.

  In the following description of the preferred embodiment of the present invention, the same or similar reference numerals are used for like elements shown in the various figures, and these elements will not be described repeatedly. Absent.

  FIG. 1 is a conceptual diagram showing a temperature adjustment device 100 according to an embodiment of the present invention. Here, the temperature adjusting device 100 is formed of a laminated body of four temperature adjusting elements 105. Only one of the temperature adjusting elements 105 is provided with a reference numeral so as not to be complicated. In addition, the temperature adjustment device 100 may include a greater or lesser number of the temperature adjustment elements 105.

Each of the temperature control elements 105 in FIG. 1 includes a first Peltier element layer 110, a second Peltier element layer 115, a first thermal conductor layer 120, a second thermal conductor layer 125, and yet another Two thermal conductor layers 130 are provided. In FIG. 1, the second thermal conductor layer 125 forms the base of the stack. The first Peltier element layer 110 is disposed on the base portion, and the first thermal conductor layer 120 is disposed on the first Peltier element layer. The first thermal conductor layer is covered with the second Peltier element layer 115. Finally, the second thermal conductor layer 130 exists on the second Peltier element layer. In FIG. 1, the first Peltier element layer 110 and the second Peltier element layer 115 are each composed of three individual Peltier element conductors 135 arranged so as to be spaced apart from each other. Only one of the Peltier element conductors 135 is labeled to avoid complications. In FIG. 1, the Peltier element conductor 135 of the first Peltier element layer 110 is doped n-type, and the Peltier element conductor 135 of the second Peltier element layer 115 is doped p-type.

  In the case of this embodiment of the temperature adjusting device 100 of FIG. 1, the first thermal conductor layers 120 are each configured as a coolant passage. Each of the second thermal conductor layer 125 and the further second thermal conductor layer 130 includes fins each having two bridges arranged in parallel and fins arranged obliquely between the bridges. It is implemented as a member. A galvanic insulating layer 140 is disposed between each two adjacent temperature adjusting elements 105. Only one of the galvanic insulating layers 140 is labeled so as not to be complicated. Optionally, one of the two bridges of the fin member 130 may not be present, for example when two temperature adjustment elements 105 are continuous in the stack, thereby providing a temperature adjustment. The second thermal conductor layer 125 of the element 105 is adjacent to the further second thermal conductor layer 130 of the subsequent temperature regulating element 105 and possibly only separated by the galvanic insulating layer 140. Has been placed. Here, for example, each of the bridges adjacent to the insulating layer 140 can be omitted. Adjacent layers may be in direct contact with each other.

  In the embodiment shown in FIG. 1 of the temperature regulating device 100, each of the second thermal conductor layers 125 has a first electrical contact 145, and the further second thermal conductor layer 130. Has a second electrical contact 150. In order to establish an electrical series connection between the temperature adjusting elements 105, the second contact 150 of the temperature adjusting element 105 is connected to the first contact 145 of the adjacent temperature adjusting element 105 via the electric wire 155. It is connected. In FIG. 1, the first contact 145 of the uppermost temperature adjustment element 105 and the second contact 150 of the lowermost temperature adjustment element 105 in the temperature adjustment device 100 are an electric supply line or a transmission line. So that the current fed into the temperature control device 100 by the supply line flows through the entire laminate and exits the laminate again through the delivery line. it can.

  Each heating element or each temperature adjusting element 105 in FIG. 1 includes a coolant passage 120 and air passage portions 125 and 130. Heat is transported between the coolant and the Peltier element 135 and between the Peltier element 135 and the finned air sides 125, 130 via the Peltier element 135. The advantageous electrical coupling 155 provides a structural principle that can be easily manufactured. Furthermore, the heating body 105 does not require an electrical insulator which generally has an unfavorable effect on the heat conduction characteristics in the required high heat transfer range.

  A coolant flows through the coolant passage 120. The Peltier elements 135 are joined to these coolant passages on both sides, whereby heat transfer can be performed in both directions. This heat is transferred through the Peltier element 135 and reaches the air side 125, 130 with the fin, which facilitates heat transfer to the air. This heat transfer is performed even in an electrically conductive state without interruption. This is because the conductive heat conductor layers 120, 125, and 130 are made of metal, for example, aluminum, and the Peltier element 135 includes a thermoelectrically active functional material. The electrical insulating layer 140 exists in the center between the corrugated fins 125 and 130. Even if there is a heat transfer resistance due to the insulating layer 140, it is not important. This is because here, according to symmetry, heat transfer in the vertical direction is not performed based on the principle of operation.

  Each of the Peltier elements 135 shown in FIG. 1 is exclusively p-type or n-type and mounted in a row (layer). The electrical coupling 155 is implemented such that the total voltage drop in the temperature regulator 100 is increased by extending the temperature regulator 100 in the vertical direction by increasing the number of layers of the temperature regulator 105. The In the embodiment shown in FIG. 1, the temperature adjusting device 100 includes four layers of temperature adjusting elements 105 each having the same internal structure. On the other hand, when the temperature adjusting device 100 is expanded in the horizontal direction, the current intensity is increased by electrically connecting all the elements of the layer in parallel.

  In FIG. 1, the fin members or air sides 125, 130 of two adjacent vertical layers, respectively, are shown in this view so that the Peltier element 135 directly joined to the air sides 125, 130 has a different doping. Then, they are connected via a separate conductor 155 represented as “cable”. The connection between the two layers of the Peltier element 135 joined to the same coolant passage 120 does not need to be bridged by separate conductors because the coolant passage 120 itself is conductive.

  Of course, depending on the configuration, layers that are not directly adjacent may be coupled together, but adjacent layers are easier because the required wire length is the shortest. Available and preferred. Similarly, by rotating the temperature control element layer 105 by 180 °, it is possible to prevent one doping from always being above and the other doping from being always below. However, the arrangement shown in FIG. 1 in which the layers of the temperature adjusting element 105 are always the same is more useful for avoiding defects during manufacturing. The electrical connections 145, 150 are suitable for smoothly adapting to the connection principle, as shown in FIG. As described above, the range of voltage drop in the heating body 100 is determined by the number of layers of the temperature adjusting element 105. When this range is too large for a given level of the heating body 100, the electrical coupling can be interrupted by further electrical supply lines. In one embodiment, the heating element portion of FIG. 1 can be precisely duplicated and placed on top of an existing heating element portion. In that case, the separation would be purely electrical and the mechanical bonding could be performed in the same way as the bonding between the other layers. However, rather, what is expected is that the voltage drop will occur when the voltage provided by the voltage source needs to be extracted as completely as possible, for example, 12 volts in a vehicle low voltage onboard power supply system. It will be too small. In this case, an electric series connection is made by arranging a plurality of heating elements 100 of this type in a row in a depth dimension not conventionally used so that a free flow cross section on the air side can be maintained. It is also possible to extend This aspect of the method according to the invention is described in connection with FIG.

  Once again, in summary with respect to the embodiment shown in FIG. 1 of the temperature control device 100, the current flow can be described as follows. That is, the current passes through a series of Peltier elements 135 having the same type of doping in parallel connection and flows to the cooling water passage 120, through which other passages are connected in the same manner. A series of elements 135 doped in the mold is reached. There is an electrical connection 150 to the conductor 155 on the air side 125, here a fin part or substrate with fins applied by brazing, for example, which is optionally implemented. Through this conductor, a current flows into the fin part or the substrate 130 with fins applied, for example by brazing, in another layer 105. In each of the elements adjacent to each other in electrical series connection, the doping type is alternately changed.

  FIG. 2 is a conceptual diagram showing a temperature adjustment device 200 according to still another embodiment of the present invention. The temperature adjustment device 200 has substantially the same structure as the temperature adjustment device 100 of FIG. 1 except that each temperature adjustment element 105 has an outer electrical connection portion 205 for bypassing the coolant passage 120. ing. Only one of the electrical connections 205 is labeled so as not to be complicated. The reason for using the electrical connection 205 is due to the fact that a purely organic coolant is generally not used but a coolant containing some moisture is used. As a result, the coolant is conductive and will be exposed to a voltage difference when used in the temperature regulator of FIG. This can be avoided by taking the coolant passage 120 out of the current cascade. Accordingly, for example, a non-conductor is applied in a thin layer on the coolant tube 120, thereby reducing the heat transport resistance as much as possible. Moreover, a continuous conductor layer is preferably applied thereon. Thus, the coolant passage 120 itself remains unpotential but must be bypassed by the separate conductor 205 for the application of the conductor layer. This is also true for the air sides 125,130. The conductor 205 may have an embodiment different from that shown in FIG.

  FIG. 3 is a detailed enlarged view showing the structure of the coolant passage 120 according to the embodiment shown in FIG. Here, a portion of the coolant passage 120 is shown as a longitudinal cross-sectional view. A galvanic insulating layer 305 made of an insulator is attached on the coolant passage 120, so that the voltage transmitted to the tube wall 310 is not transmitted to the cooling fluid flowing through the coolant passage 120. . A conductor layer 315 made of a conductor is attached over the entire galvanic insulating layer 305. In addition, the conductor layer 315 has an electrical contact to the current collector 320, and this current collector can take the current from here and supply it again to the conductor layer 315 from another location. The cooling fluid continues to be excluded from the current flow. The tube wall 310 can be made of aluminum, for example.

  FIG. 4 is a conceptual diagram illustrating an alternative embodiment of the temperature adjustment device 400. The temperature adjustment device 400 includes a vertical stack of three temperature adjustment elements 405. These temperature adjustment elements have a different structure from the temperature adjustment elements described in connection with FIG. Here, in addition to the first thermal conductor layer 120, the second thermal conductor layer 125 is also disposed between the first Peltier element layer 110 and the second Peltier element layer 115. Yes. A galvanic / thermal insulating layer 410 exists between the first thermal conductor layer 120 and the second thermal conductor layer 125. The galvanic and thermal insulation layer 410 may have an optional bridge for the fin member 125 or for the fin member 130. The galvanic insulating layer described in connection with FIG. 1 is not used here. In the case of the embodiment shown here, the temperature adjustment element 405 has a further first heat conductor layer 415, which forms the basis of the temperature adjustment element 405. Here, the first thermal conductor layer 120 has the first electrical contact 145 and the further first thermal conductor layer 415 has the second electrical contact 150. Further, the second heat conductor layer 125 of each temperature adjusting element 405 is connected to the second heat conductor layer 130 via the electric wire 420.

  In FIG. 4, unlike the embodiment described in connection with FIG. 1, there is only heat transfer on one side on the low temperature side and the high temperature side, respectively. Therefore, the insulating layer 410 has not only electrical insulation against low voltage on the other side, but also thermal insulation. Accordingly, the thickness of the insulating layer 410 may be greater here. Here, the air sides 125, 130 of adjacent layers are electrically connected to each other via the wire 420. Similarly, the cooling water sides 120, 415 of adjacent layers are not directly connected, but are electrically connected to each other indirectly via separate conductors 425, similar to the air side. Yes. Also, this connection is made so that the doping types of the Peltier pellets 135 that are identically doped in the layers of the two electrically connected layers 120, 415 or 125, 130 are alternated. Is done.

  It is emphasized in the context of the embodiments described with reference to FIGS. 1 to 4 above that the method presented here uses an absolute order, ie a predetermined doping (p-type or n-type). This means that the start and end of the series connection provided and the number of Peltier elements in each spatial direction remain undefined in principle. Similarly, it is not determined whether the operation is an operation as a heat pump in which air is heated or an operation as an air conditioning facility in which air is cooled. Each of the functions can be switched by polarity inversion.

  FIG. 5 is a conceptual diagram showing an embodiment of an electrical series connection 500 in which the temperature control device 100, 200 or 400 of FIGS. 1 to 4 is expanded in the horizontal direction. The plurality of temperature control devices 100, 200 or 400 are shown in a simplified form. In FIG. 5, the temperature control devices 100, 200, or 400 are arranged side by side in the depth direction 510 indicated by the arrows on one plane. Depending on the constructional conditions of the place of use, the arrangement 500 shown here can be further expanded with the addition of another temperature control device 100, 200 or 400. The individual temperature control devices 100, 200, or 400 are connected to each other so as to be conductive, thereby allowing current to flow through the entire arrangement 500. The electrical connection is not shown in FIG. Another arrow indicates, for example, the flow direction 520 of the heat transfer fluid that is induced in the second heat conductor layer and the further second heat conductor layer of the temperature adjusting device 100, 200 or 400. Indicates. This heat transfer fluid may be air, for example.

  As an alternative to the embodiments presented in FIGS. 1 to 4 of the temperature regulating device 100, 200 or 400, a further embodiment of the temperature regulating device according to the invention comprises a Peltier element layer, and this Peltier element The layer has a plurality of Peltier elements, and these Peltier elements have a plurality of Peltier element conductors. Thus, instead of a pure n-type or p-type doped element 135, an element that is geometrically identical on the outer surface, in itself, of n-type and p-type connected chips It is possible to use an element having an arbitrary planar fine structure.

FIG. 6 is a conceptual diagram showing a Peltier element 600 as a reference example . A horizontal arrangement of Peltier element conductors 135 is shown. In this case, n-type doped Peltier element conductors and p-type doped Peltier element conductors are alternately arranged in one plane. Peltier element conductors 135 arranged adjacent to each other and doped differently from each other are alternately connected to each other via a conductor 605 on the high temperature side and further another conductor 605 on the low temperature side. . An interruption portion 610 of the conductor 605 exists on the high temperature side or the low temperature side facing the respective conductors. Electrical insulators 615 are respectively disposed above and below the layer of the Peltier element conductor 135.

Temperature adjustment equipment using a Peltier element 600, which may have been constructed in accordance with the principles of temperature regulation device 100, 200, 400 shown in Figures 1-4, In this case, the flow of current In order to ensure that it passes through the entire stack of temperature control devices thus configured, here, unlike the illustrated embodiments 100, 200, 400, each Peltier element 600 is It has a current supply line and a delivery line. Unlike the embodiment of FIGS. 1-4, here the current flows through the respective Peltier elements 600 in the horizontal direction rather than in the vertical direction. The individual Peltier elements 600 can be connected in series or in parallel, and in the case of parallel connection, each Peltier element 600 is a central power supply part of a vehicle, typically a central power supply part of a car battery. This ensures a voltage drop of 12 mm across the stack of the temperature control device.

In one embodiment in which the Peltier element 600 is used, current does not pass through the entire stack, in particular through the thermal conductor layer, but only through the Peltier element layer. Wherein each of the Peltier element can be tied in parallel or in series.

  Depending on the voltage drop in the Peltier element 600, it is possible to use the electrical coupling described here between the rows, thereby further increasing the overall voltage drop across the heating element. Will. Or, for example, when the fine structure of the Peltier module 600 already causes a voltage drop of 12 V as in the conventional function, each column including the thermoelectric elements 600 can be easily handled as an individual circuit. For example, an n-type or p-type chip or an n-type or p-type Peltier element conductor can have a voltage drop of 0.0625∨. Therefore, in the case of 16 chips, 1V is generated for one Peltier element. If the heating element has twelve series-connected rows, a total voltage drop of 12∨ will be realized.

FIG. 7 is a perspective view illustrating a planar layer, particularly a Peltier element layer 710 having a plurality of Peltier elements 600 according to an embodiment of the present invention . Before SL Peltier element 600, respectively, it may be a module as shown in Figure 6 for example. The individual Peltier elements 600 are separated from each other by a thermally insulated intermediate space 712. The direction of heat flow is indicated by arrows.

FIG. 8 is a schematic diagram showing a temperature adjustment device 800 including a plurality of Peltier element layers . The temperature adjusting device has a laminate composed of, for example, a heat conductor layer denoted by reference numeral 125 in one air passage and a Peltier element layer denoted by reference numeral 710 by way of example. Example of this, as indicated by the arrows, hot air flows into the temperature regulation device 800, cold air flows out from the temperature adjustment device 800. What this means is that the Peltier element is arranged to cool the air passage 125 or behaves like that. On the other hand, in the case of the further heat conductor layer through which the coolant can circulate, for example, the temperature adjusting device 800 is heated.

The left side of FIG. 9 shows the layers of the temperature control device shown in FIG. 8, and the right side shows an exploded view of this layer. Shown here is a layered structure comprising a first thermal conductor layer 120, two second thermal conductor layers 125, and two Peltier element layers 710. The Peltier element layer 710 is disposed between the first thermal conductor layer 120 and one of the second thermal conductor layers 125, respectively. The first heat conductor layer 120 is configured in the form of a flat coolant passage, and the coolant 950 flows through the coolant passage. The Peltier element layer 710 can be formed as a Peltier layer including an electrical contact portion and an electrically insulating portion by material bonding.

Figure 10 shows the relationship between the Peltier element layer 710 and the Peltier element 600 in FIG.

The occupation ratio ε can be 10% or less. That is,
ε = (total area of Peltier element 600) / (area of layer 710) ≦ 10%
The Peltier element 600 includes a substrate and a cover plate, and a plurality of Peltier element conductors are disposed therebetween. The arrangement of the Peltier element conductors can be carried out in accordance with the arrangement shown in FIG.

In the reference example shown in FIG. 10, the entire device 600 is provided in the layer 710 instead of the doped pellet. In this case, a maximum of 10% of the area of the layer 710 is occupied by the Peltier element 600. Therefore, the integrated plane is not located in the doped p-type and n-type pellets, and the entire procurement element having a unique microstructure, i.e., p-type and n-type, can be embedded. The fine structure may be composed of pellets. Instead of bonded pellets, it is also possible to use, for example, deposited conductive paths or fabrics.

One embodiment of the present invention can be used in thermoelectric heating equipment and air conditioning equipment. Modular equipment is used to heat or cool cabin air. Heat reception or heat transfer takes place via a low temperature circuit of the vehicle, preferably an electric vehicle. The basic structure of the device is envisioned to provide the best heat transfer so that it is beneficial to use conventionally available thermoelectric materials.

  In electric vehicles, significant engine waste heat cannot be utilized, so heating the cabin is a challenge. The electric resistance heater converts the current stored in the battery into heat with COP = 1 (UK: Coefficient of Performance), and considerably reduces the cruising distance. More efficient are heat pumps that operate with COP> 1 and obtain heat from some current and some from ambient or low temperature waste heat sources. In addition to using a coolant heat pump, thermoelectric materials that are effective without moving members or coolants are also suitable. An ideal situation would be when the same thermoelectric element can be used to provide a cabin cooling function (summer mode). In this case, the entire refrigeration circuit is not necessary, and switching between heating and cooling will be realized by reversing the polarity of the applied voltage without mechanical changes.

By the present invention, to realize the function of "heat of the cabin" in COP> 1 (heat-pump operation), and it is possible to eliminate the separate refrigeration circuits by electrical switching to cooling operation. In this case, the COP in the cooling operation should not be inferior to the COP of the refrigeration circuit.

  A key feature of heating and air conditioning equipment that utilizes the Peltier effect is that the amount of heat transfer is clearly increased by using the smallest possible temperature difference between the fluid and the thermally coupled sides of the thermoelectric element. It is to be done. Since the efficiency of heat exchangers quickly reaches its limit, the solution remains to produce a slight drive temperature difference by greatly reducing the heat flow density transferred. The relationship that the COP decreases as the temperature difference increases is much more pronounced in the thermoelectric system than in the refrigeration circuit. This is because undesired heat conduction occurs in the natural heat flow direction between the high temperature side and the low temperature side of the Peltier element. Here, in cooling operation, slight temperature differences can create differences between acceptable use and unfavorable or physically impossible configurations. This is because the following feedback mechanism exists. That is, when the COP deteriorates, the amount of heat generated on the waste heat side increases and the temperature rises there, which also deteriorates the COP and further increases the required power and the amount of heat generated on the waste heat side.

  When the output density is reduced, the amount of current supplied to the thermoelectric element cannot be easily reduced. This is because the COP is greatly deteriorated and the thermoelectric element continues to be maintained as an undesired thermal bridge between the high temperature side and the low temperature side. The semiconductor used generally has a single-digit level heat transfer coefficient (W / m2K). Instead, the Peltier element must be applied with an optimal current strength that can be calculated or stored as a characteristic map, and when the Peltier element reduces the power density, Only a small area is allowed for each of these mounting plane layers. The area not occupied by the thermoelectric material can be filled with, for example, an insulating material, air or gas, as shown in FIG.

  The plane layer of the Peltier element so that an overall acceptable volumetric power density is available and the combined heating and cooling equipment structure as shown in FIG. 8 is not too large. The small power density at must be compensated by keeping the layers as close as possible in the remaining dimensions. Although the air passage is shown with fins in FIG. 8, it naturally has fins.

  Increasing the desired benefits and effects by directing the cabin air and coolant flow back as shown in FIG. 8 and the individual layers as shown in FIG. It can be increased by joining by material bonding. For example, a very thin electrically insulating layer can be deposited by material bonding. Ideally, in each layer, the layers continuing toward each side, that is, the Peltier element → conductor → electrical insulator → flow path (coolant side or air side) bottom are joined by material bonding, And it is implemented so that it may be only a thickness that is essential to fulfill those roles. The coolant passage 120 may be equipped with a baffle, a turbulator, etc., but this coolant passage is thermally coupled to the thermoelectric element on both sides as shown in FIG. Yes. A further advantage of this configuration is that it is a modular structure, which allows the distributed components to be adapted by appropriately adapting the number of layers and by appropriately selecting the dimensions of the plane. It is possible to develop and these dispersive components can be installed in the vicinity of the corresponding outflow opening in the front region or the rear region.

In the low temperature mode, the cooling capacity is 1200 W, the blowing temperature is 15 ° C., the coolant temperature is 35 ° C., the size is 150 × 150 × 300 mm ³ , the number of the coolant layers is 10, the actual air and coolant flow, and the appropriate thermoelectric material When the condition is satisfied, 1 ≧ COP = Q _Kaelte / P _elektrisch = 2 can be realized.

  The heating and cooling body is designed to be as close as possible to the maximum COP at one or more important operating points. If the power demand is small, i.e. the energization is reduced, the COP will worsen because the Peltier element will gradually act as a natural thermal bridge. Thus, the individual layers are not only electrically separated from the air flow after a certain power level, but also thermally separated, for example by closing the inlet. This separation can be achieved with respect to a certain number of individual layers, or alternatively over multiple layers. A finer separation stage improves COP over the entire operating cycle, and a coarser stage reduces manufacturing costs.

  For example, 12 layers can be provided in one heating / cooling body. Of the total of 6 layers, 3 layers can be closed on the air side in common. Therefore, two flaps are required. Therefore, the number of layers distributed simultaneously is as follows: 6 layers when 2 flaps are closed, 9 layers when 1 flap is closed, all flaps open Can be 12 layers.

  Furthermore, the dimensions of this component are such that the required heating or cooling output can be obtained during heating up or cooling down, i.e. during heating and cooling, without depending on the COP achieved in these stages. Must be set to

FIG. 11 is a projected view perpendicular to the drawing plane showing two adjacent Peltier element layers as a reference example . Shown here is the front Peltier element layer, that is, the upper layer in FIG. 11, comprising a plurality of Peltier elements 600 schematically shown. To avoid complication, only one of the plurality of Peltier elements 600 is denoted by reference numeral 600. Furthermore, a rear Peltier element layer comprising a plurality of Peltier elements 1600 schematically shown is shown. The Peltier element 1600 is indicated by a broken line. Here too, only one is denoted by reference numeral 1600 so as not to become complicated.

In this reference example, the front Peltier element layer and the rear Peltier element layer have different numbers of Peltier elements 600 and 1600. As an example, the front Peltier element layer has 16 Peltier elements 600 and the rear Peltier element layer has 9 Peltier elements 1600. Further, the arrangement of the Peltier elements 600 on the front Peltier element layer is different from the arrangement of the Peltier elements 1600 on the rear Peltier element layer. Shown here is a staggered arrangement, in which the rows or columns of Peltier elements 600 alternate with the rows or columns of Peltier elements 1600. In this case, the Peltier element 600 does not have an overlapping region with the Peltier element 1600. In this reference example, the Peltier element 600 and the Peltier element 1600 have the same size. The Peltier elements 600 and 1600 may be the same. Alternatively, the Peltier elements 600 and 1600 may have different sizes.

  Ideally, the surface of each Peltier element layer has a uniform temperature distribution. However, in practice, the highest temperature position or the lowest temperature position, that is, so-called hot spots and cold spots appear in the Peltier elements 600 and 1600 serving as heat sources or heat sinks. This occurs because of the limited heat conduction in the horizontal direction. The planar arrangement and number of Peltier elements 600, 1600, and additionally or alternatively, the size of the Peltier elements 600, 1600 itself may be different between two adjacent Peltier element layers. An advantage that this can provide is to reduce the formation of hot spots or cold spots, such as the number of heat sources or heat sinks acting on the fins, turbulators or fluids, ie shown in FIG. This is also caused by an increase in the number of heat sources or heat sinks acting on the projection plane in the conceptual vertical projection of both Peltier element layers and a decrease in the distance between the heat sources or heat sinks.

The above-described embodiments and reference examples are merely selected for illustration, and can be combined with each other. In particular, it is possible to combine the above-described embodiments having a Peltier element layer composed of individual Peltier element conductors with the reference example having a Peltier element layer composed of Peltier elements. In this case, the electrical coupling of the Peltier element layers can be adapted accordingly.
