Description

The present invention relates to a thermoelectric gas burner, and more specifically to a thermoelectric gas burner that can produce a large amount of electricity by burning gas in the high-temperature part after gas discharged from a gas cylinder comes into direct contact with the low-temperature part of a thermoelectric module, lowering the temperature of the low-temperature part. The temperature difference between the low-temperature part and the high-temperature part that make up the thermoelectric module becomes large, and the thermoelectric gas burner can produce a large amount of electricity.

A thermoelectric element is a device that can convert thermal energy into electrical energy by converting the temperature difference between both ends into electricity. The thermoelectric phenomenon of a thermoelectric element means the reversible and direct energy conversion between heat and electricity, and is a phenomenon that occurs when heat (phonons) is transferred by the movement of electrons and holes inside the material that constitutes the thermoelectric element.

Thermoelectric elements that use the thermoelectric phenomenon can be broadly classified into thermoelectric elements that use the Peltier effect for active cooling, and thermoelectric elements that use the Seebeck effect for waste heat power generation and other applications.

Among these, the demand and necessity for thermoelectric power generation devices that use the Seebeck effect of thermoelectric elements is increasing as a solution to environmental pollution and energy conservation problems.

These thermoelectric generators are also widely used in household appliances and devices, such as gas burners, stoves, or heating elements. Gas burners are now widely used in apartments and homes for heating and cooking both indoors and outdoors. In particular, gas burners are used for heating and cooking in many places where the power supply is limited.

When using a gas burner, the waste heat remaining after heating the heat exchanger of the gas burner is sometimes simply released to the outside and wasted. Therefore, by applying a thermoelectric generator to a gas burner, the thermal energy of the wasted gas can be converted into electricity, which can be usefully used to power electric fans, lighting, televisions, chargers, etc.

On the other hand, it is preferable for a gas burner equipped with a thermoelectric generator (hereinafter referred to as a thermoelectric gas burner) to be lightweight, small, highly portable, and capable of producing a large amount of electricity. However, conventional thermoelectric gas burners have the problem that they are large and heavy, and cannot produce a large amount of electricity due to their low conversion efficiency.

Therefore, it is necessary to develop a thermoelectric gas burner that is lightweight, compact, and capable of producing large amounts of electricity.

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings and the following description. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. The same reference numerals refer to the same elements throughout the specification.

The following describes a thermoelectric gas burner (1) according to a first embodiment of the present invention. Figure 1 is a cross-sectional view showing a thermoelectric gas burner according to a first embodiment of the present invention.

Referring to FIG. 1, the thermoelectric power generating gas burner (1) mainly includes a housing (100) and a thermoelectric module (200).

First, the housing (100) will be described. The housing (100) may have an inlet hole (110) formed on one side (the lower side as viewed in the drawing), and gas may be introduced into the inlet hole (110). The gas may be low-temperature compressed gas discharged from a gas cylinder of a gas burner. The housing (100) may also have a combustion hole (120) formed on the other side (the upper side as viewed in the drawing). Air may be introduced into the housing (100) through the combustion hole (120), and the air introduced into the combustion hole (120) may be mixed with gas and combusted in the high-temperature part (220) of the thermoelectric module described below.

On the other hand, a plurality of second heat dissipation fins (130) may be formed on the outer peripheral surface of the housing (100).

Next, the thermoelectric module (200) will be described. The thermoelectric module (200) includes a thermoelectric element (210), a high temperature part (220), and a low temperature part (230). The thermoelectric element (210) may be a conventional thermoelectric element using the Seebeck effect. The high temperature part (220) may be configured to burn gas and may contact one side (upper side as viewed in the drawing) of the thermoelectric element (210) to transfer heat to the thermoelectric element (210). The low temperature part (230) may contact the other side (lower side as viewed in the drawing) of the thermoelectric element (210) to cool the thermoelectric element (210).

The thermoelectric module (200) may be disposed inside the housing (100) such that the high temperature portion (220) faces the combustion hole (120) of the housing (100) and the low temperature portion (230) faces the inlet hole (110) of the housing (100). In this case, a plurality of first heat dissipation fins (232) may be formed on one side of the low temperature portion (230) facing the inlet hole (110).

Also, as shown in FIG. 1, the thermoelectric module (200) may be disposed inside the housing (100) such that a mixing flow path (10) is formed between the outer peripheral surface of the thermoelectric module (200) and the housing (100).

Next, the operation of the thermoelectric gas burner (1) will be explained.

Since the thermoelectric module (200) is disposed inside the housing (100), the gas flowing into the inlet (110) can come into direct contact with the low-temperature portion (230) and cool the low-temperature portion (230). Because the gas flows into the inlet (110) at a high speed, the low-temperature portion (230) can come into contact with a large amount of gas per unit time and be cooled.

At this time, a plurality of first heat dissipation fins (232) are formed on one side of the low-temperature portion (230) that comes into contact with the gas, so that the low-temperature portion (230) can release a greater amount of heat and cool when it comes into contact with the gas.

Also, as shown in FIG. 1, the low-temperature section (230) and the housing (100) may be connected by a first heat transfer member (20) capable of transferring heat. When the low-temperature section (230) and the housing (100) are connected by the first heat transfer member (20), the heat of the low-temperature section (230) may be transferred to the housing (100) and dissipated by the second heat dissipation fins (130).

The gas that comes into contact with the low-temperature section (230) and cools it is transferred to the high-temperature section (220) while mixing with air along the mixing flow path (10). The high-temperature section (220) is positioned opposite the combustion hole (120), so the gas transferred to the high-temperature section (220) can be mixed with the air flowing in from the combustion hole (120) and completely combusted.

The following describes a thermoelectric gas burner (2) according to a second embodiment of the present invention. Figure 2 is a cross-sectional view showing a thermoelectric gas burner according to a second embodiment of the present invention.

Referring to FIG. 2, the thermoelectric power generating gas burner (2) mainly includes a housing (300) and a thermoelectric module (400).

First, the housing (300) will be described. The housing (300) may have an inlet hole (310), a combustion hole (320), and a fourth heat dissipation fin (350), and the housing (300) may include a first bypass pipe (330) and a second bypass pipe (340).

The inlet hole (310) may be formed on one side (lower side as viewed in the drawing) of the housing (300), and gas may be introduced into the inlet hole (310). The combustion hole (320) may be formed on the other side (upper side as viewed in the drawing) of the housing (300), and air may be introduced into the housing (300) through the combustion hole (320). The air that has flowed into the combustion hole (320) may be mixed with gas and combusted in the high-temperature portion (420) of the thermoelectric module described below.

Meanwhile, a plurality of fourth heat dissipation fins (350) may be formed on the outer peripheral surface of the housing (300).

Next, the thermoelectric module (400) will be described. The thermoelectric module (400) includes a thermoelectric element (410), a high temperature part (420), and a low temperature part (430). The thermoelectric element (410) may be a conventional thermoelectric element using the Seebeck effect. The high temperature part (420) may be configured to burn gas and may contact one side (upper side as viewed in the drawing) of the thermoelectric element (410) to transfer heat to the thermoelectric element (410). The low temperature part (430) may contact the other side (lower side as viewed in the drawing) of the thermoelectric element (410) to cool the thermoelectric element (410), and may have a gas passage (432) passing through the inside.

In this case, the first bypass pipe (330) may be configured so that one end communicates with the inlet hole (310) and the other end communicates with one end of the gas flow path (432), and the second bypass pipe (340) may be configured so that one end communicates with the inlet hole (310) and the other end communicates with the other end of the gas flow path (432).

On the other hand, as shown in FIG. 2, the distance between one end of the first bypass pipe (330) communicating with the inlet (310) and the low temperature section (430) may be greater than the distance between one end of the second bypass pipe (340) communicating with the inlet (310) and the low temperature section (430).

In addition, a plurality of third heat dissipation fins (434) may be formed on one side of the low-temperature portion (430) facing the inlet hole (310). Such a thermoelectric module (400) may be disposed inside the housing such that the high-temperature portion (420) faces the combustion hole (320) of the housing (300) and the low-temperature portion (430) faces the inlet hole (310) of the housing (300).

Also, as shown in FIG. 2, the thermoelectric module (400) may be disposed inside the housing (300) such that a mixing flow path (30) is formed between the outer peripheral surface of the thermoelectric module (400) and the housing (300).

Next, the function of the thermoelectric gas burner (2) will be explained.

When gas flows into the inlet hole (310), a portion of the gas flows into the first bypass pipe (330) and is transferred to the gas flow path (432), and the gas transferred to the gas flow path (432) cools the low-temperature section (430) while passing through the inside of the low-temperature section (430). The gas is also discharged from the gas flow path (432) and flows into the second bypass pipe (340) and is discharged to the inlet hole (310).

On the other hand, the gas discharged from the second bypass pipe (340) to the inlet hole (310) absorbs heat while passing through the gas flow path (432), and therefore has a higher temperature than the gas flowing into the inlet hole (310) from outside the housing. If the gas with such a high temperature flows into the first bypass pipe (330) and is transferred to the gas flow path (432), the cooling efficiency of the low-temperature part (430) may decrease. Therefore, in order to prevent this, one end of the first bypass pipe (330) communicating with the inlet hole (310) is located farther from the low-temperature part (430) than one end of the second bypass pipe (340) communicating with the inlet hole (310), so that the gas discharged from the second bypass pipe (340) to the inlet hole (310) does not flow into the first bypass pipe (330).

The remaining gas that does not flow into the first bypass pipe (330) among the gases that flow into the inlet (310) and the gas that is discharged from the second bypass pipe (340) are both transferred to the low temperature section (430) and come into direct contact with the low temperature section (430), thereby cooling the low temperature section (430). Because the gas flows into the inlet (310) at a high speed, the low temperature section (430) can come into contact with a large amount of gas per unit time and be cooled.

At this time, a plurality of third heat dissipation fins (434) are formed on one side of the low-temperature portion (430) that comes into contact with the gas, so that the low-temperature portion (430) can release an even greater amount of heat and cool when it comes into contact with the gas.

In addition, the low-temperature portion (430) and the housing (300) may be connected by a second heat transfer member 40 capable of transferring heat, and when the low-temperature portion (430) and the housing (300) are connected by the second heat transfer member 40, the heat transferred from the low-temperature portion (430) to the housing (300) may be dissipated by the fourth heat dissipation fin (350) of the housing (300) described above.

The gas that has cooled the low-temperature section (430) is transferred to the high-temperature section (420) while mixing with air along the mixing flow path (30). The high-temperature section (420) is positioned opposite the combustion hole (320), so the gas transferred to the high-temperature section (420) can be mixed with the air flowing in from the combustion hole (320) and completely combusted.

The following describes a thermoelectric gas burner (3) according to a third embodiment of the present invention. Figure 3 is a cross-sectional view showing a thermoelectric gas burner according to the third embodiment of the present invention.

Referring to FIG. 3, the thermoelectric power generating gas burner (3) mainly includes a housing (500), a burner (600), and a thermoelectric module (700). That is, in the first and second embodiments, the high temperature part of the thermoelectric module also serves as the burner, but in this embodiment, the burner and the high temperature part of the thermoelectric module are formed separately.

First, the housing (500) will be described. The housing (500) may have an inlet hole (510) and a combustion hole (520). The inlet hole (510) may be formed on one side (lower side as viewed in the drawing) of the housing (500), and gas may be introduced into the inlet hole (510). The combustion hole (520) may be formed on the other side (upper side as viewed in the drawing) of the housing (500), and air may be introduced into the housing (500) through the combustion hole (520). The air introduced into the combustion hole (520) may be mixed with gas and combusted in the burner (600) described below.

Next, the burner (600) will be described. The burner (600) may be disposed inside the housing (500) so as to face the combustion hole (520), and gas can be burned on one side of the burner (600) facing the combustion hole (520).

Also, as shown in FIG. 3, the nozzle (600) may be disposed inside the housing (500) such that a mixing flow path (50) is formed between the outer peripheral surface of the nozzle (600) and the housing (500).

Next, the thermoelectric module (700) will be described. The thermoelectric module (700) may include a thermoelectric element (710), a high temperature part (720), and a low temperature part (730), and may be disposed outside the housing (500). The thermoelectric element (710) may be configured as a conventional thermoelectric element using the Seebeck effect. One side (upper side as viewed in the drawing) of the high temperature part (720) and the burner (600) may be connected by a third heat transfer member (610). The third heat transfer member (610) may function to transfer heat generated in the burner (600) to the high temperature part (720). In addition, the other side (lower side as viewed in the drawing) of the high temperature part (720) may contact one side (upper side as viewed in the drawing) of the thermoelectric element (710) to transfer heat transferred from the burner (600) to the thermoelectric element (710). The low-temperature portion (730) may be in contact with the other side (the lower side in the drawing) of the thermoelectric element (710) to cool the thermoelectric element (710), and the low-temperature portion (730) may have a gas passage (732) formed therethrough.

In addition, a plurality of fifth heat dissipation fins (734) may be formed on the surface of the low temperature section (730) opposite to the surface in contact with the thermoelectric element (710).

Next, the function of the thermoelectric gas burner (3) will be explained.

The gas flowing into one side of the gas flow path (732) of the low-temperature part (730) cools the low-temperature part (730), and is then discharged to the other side of the gas flow path (732) and transported to the inlet (510) of the housing (500). At this time, a connecting pipe (760) may be provided to connect the other side of the gas flow path (732) from which the gas is discharged and the inlet (510) of the housing (500). The low-temperature part (730) is cooled by the gas flowing through the gas flow path (732) and is cooled by discharging heat to the fifth heat dissipation fin (734) formed in the low-temperature part (730). The gas transported to the inlet (510) flows into the inside of the housing (500) and is transported to the burner (600) while being mixed with air along the mixing flow path (50). One side of the burner (600) where the gas is burned faces the combustion hole (520), so the gas transferred to the burner (600) can be mixed with the air flowing in from the combustion hole (520) and burned completely.

The following describes a thermoelectric gas burner (4) according to a fourth embodiment of the present invention. Figure 4 is a cross-sectional view showing a thermoelectric gas burner according to the fourth embodiment of the present invention.

Referring to FIG. 4, the thermoelectric power generating gas burner (4) mainly includes a housing (800), a thermoelectric module (900), and an inlet pipe (1000).

First, the housing (800) will be described. The housing (800) may have an inlet hole (810), a combustion hole (820), and a seventh heat dissipation fin (830). The inlet hole (810) may be formed on one side (lower side based on the drawing) of the housing (800), and the inlet pipe (1000) described later may be inserted into the inlet hole (810). The combustion hole (820) may be formed on the other side (upper side based on the drawing) of the housing (800), and air may be introduced into the housing (800) through the combustion hole (820). The air introduced into the combustion hole (820) may be mixed with gas and combusted in the high temperature part (920) of the thermoelectric module described later.

Meanwhile, a number of seventh heat dissipation fins (830) may be formed on the outer peripheral surface of the housing (800).

Next, the thermoelectric module (900) will be described. The thermoelectric module (900) includes a thermoelectric element (910), a high temperature part (920), and a low temperature part (930). The thermoelectric element (910) can be a conventional thermoelectric element using the Seebeck effect. The high temperature part (920) may be configured to burn gas and may contact one side (upper side as viewed in the drawing) of the thermoelectric element (910) to transfer heat to the thermoelectric element (910). The low temperature part (930) may contact the other side (lower side as viewed in the drawing) of the thermoelectric element (910) to cool the thermoelectric element (910), and the low temperature part (930) may be formed with an inlet flow path (932) through which gas flows in and an outlet flow path (934) through which gas is discharged.

In addition, a plurality of sixth heat dissipation fins (936) may be formed on one side of the low-temperature portion (930) facing the inlet hole (810), i.e., on the side opposite to the side of the low-temperature portion (930) that contacts the thermoelectric element (910). In this case, the sixth heat dissipation fins (936) of the low-temperature portion (930) may be configured so that at least a portion of the sixth heat dissipation fins (936) contacts the housing (800).

Such a thermoelectric module (900) may be disposed inside the housing such that the high temperature portion (920) faces the combustion hole (820) of the housing (800) and the low temperature portion (930) faces the inlet hole (810) of the housing (800).

Also, as shown in FIG. 4, the thermoelectric module (900) may be disposed inside the housing (800) such that a first space (60) is formed between the outer peripheral surface of the thermoelectric module (900) and the housing (800).

Next, the inlet pipe (1000) will be described. The inlet pipe (1000) may be composed of a pipe having a plurality of holes (1010) formed therein so that the gas flows in and is connected to the outside, or may be connected to the inlet flow passage (932) of the low-temperature section (930) from the outside of the housing (800) through the inlet holes (810).

Next, the function of the thermoelectric gas burner (4) will be explained.

The gas is transported along the inlet pipe (1000) to the inlet flow path (932) of the low temperature section (930). At this time, air flows into the inlet pipe (1000) through a plurality of holes (1010) formed in the inlet pipe (1000), so that the gas flowing through the inlet pipe (1000) can be mixed with the air.

The gas transferred to the inlet flow passage (932) flows into the inlet flow passage (932) and is discharged to the exhaust flow passage (934) to cool the low temperature section (930). The gas discharged to the exhaust flow passage (934) is accommodated in the first space (60) and can move to the high temperature section (920) to be combusted. One side of the high temperature section (920) where the gas is burned faces the combustion hole (820), so the gas transferred to the high temperature section (920) can be mixed with the air flowing in from the combustion hole (820) and completely combusted.

Meanwhile, since the sixth heat dissipation fin (936) of the low-temperature section (930) is at least partially in contact with the housing (800), the heat of the low-temperature section (930) is transferred to the housing (800) and can be dissipated by the seventh heat dissipation fin (830) formed on the housing (800).

Figure 5 is a cross-sectional view showing the schematic overall structure of the thermoelectric gas burner of the present invention.

As shown in FIG. 5, the thermoelectric gas burner of the present invention may be configured so that gas discharged from a gas cylinder (6) provided inside the main body (5) flows into the housing (9) in which the thermoelectric module (7) is provided.

The gas that flows into the housing (9) cools the low-temperature part of the thermoelectric module (7), and is then transferred to the burner or the high-temperature part of the thermoelectric module (7), where it is burned while generating a flame (11), thereby heating the high-temperature part of the thermoelectric module (7).

However, it goes without saying that the invention is not limited to this and the thermoelectric gas burner does not have to have a separate body (5) that surrounds the gas cylinder (6) and the housing (9).

In this way, the thermoelectric gas burner of the present invention does not require a separate fan or cooling device to cool the low-temperature part of the thermoelectric module, as the gas discharged from the gas cylinder comes into direct contact with and cools the low-temperature part of the thermoelectric module, making it possible to manufacture a small and lightweight thermoelectric gas burner.

In addition, the low-temperature part of the thermoelectric module is configured to come into direct contact with a large amount of gas per unit time, or to allow gas to pass through the inside of the low-temperature part of the thermoelectric module, so that the temperature difference between the high-temperature part and the low-temperature part of the thermoelectric module becomes large, allowing a larger amount of electricity to be produced.

The above description of the present invention is for illustrative purposes only, and a person having ordinary knowledge in the technical field to which the present invention pertains will understand that the present invention can be easily modified into other specific forms without changing the technical concept or essential features of the present invention. Therefore, the above-described embodiments should be understood as illustrative in all respects and not limiting. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.

The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications and variations derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.

The present invention relates to a thermoelectric gas burner, and more particularly to a thermoelectric gas burner in which gas discharged from a gas cylinder comes into direct contact with a low-temperature part of a thermoelectric module to lower the temperature of the low-temperature part and then burns in the high-temperature part, thereby increasing the temperature difference between the low-temperature part and the high-temperature part that constitute the thermoelectric module and enabling the production of a large amount of electricity.
