Description

The present invention relates to a fluid cooling device that cools or heats a fluid contained in a container. In this specification, the fluid substance refers to a substance having fluidity in at least a part of the temperature range from the high temperature at the start of cooling to the low temperature at the end of cooling, and at the end of cooling, a soup-like substance having a low viscosity. It also includes those that are in the form of gel with high viscosity.

For example, fluid cooked foods such as soups, noodle soups, curries, meat sauces, eight treasures, and beverages manufactured at food factories and school lunch centers are quickly cooled after manufacturing in order to suppress the growth of bacteria. There is a need. Conventionally, a vacuum cooling device, a differential pressure cooling device, or the like has been used as the cooling device for that purpose. However, all of these devices are expensive, and the vacuum cooling device has a problem that the food component evaporates, causing a loss and a change in taste, and the differential pressure cooling device has a problem that the cooling time is long. On the other hand, as a device that can be constructed at low cost, there is a jacket type cooling device in which a cooling fluid such as cold water is allowed to flow outside the container to exchange heat with a fluid inside through the container.

As such a jacket type cooling device, for example, the hopper of the hopper member and the cover body are doubly combined to form a sealed cylindrical space, and the hopper body is formed on at least one of the outer wall surface of the hopper and the inner wall surface of the cover body. , A plurality of shielding blades forming an escape path in a maze state are provided so as to be located in the circumferential direction of the cylindrical space, and cooling water is poured into the cylindrical space through an introduction path provided in the hopper member, and the cooling water is poured into the cylindrical space. By guiding the cooling water that has flowed into the hopper to the outlet of the hopper member through the escape path while diffusing it with the shielding blades, the edible substances such as soups, fruit drinks, and fluids in the hopper are evenly and totally. A fluid circulation device for cooling is known (see Patent Document 1).

However, in the cooling method in which the cooling medium is guided only to the outside of the hopper as described above, the fluid material contacts only the inner wall of the hopper, and heat exchange between the fluid material and the cooling medium is performed through the inner wall. Therefore, it has only the cooling capacity corresponding to the surface area of the inner wall, and there is a problem that the heat transfer efficiency is poor. Further, such a problem is naturally the same even when a heating medium such as a high-temperature liquid or gas is used instead of the cooling medium.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a fluid cooling device having high heat transfer efficiency.

In order to solve the above problems, one aspect of the present invention is a fluid cooling device that cools or heats a fluid contained in a container, and exchanges heat with the fluid inside. The conduit through which the heat exchange medium flows is formed by being bent along the surface of a predetermined shape, and the fluid is brought into contact with the outer periphery of the conduit to cool or heat the fluid, and the conduit. An introduction pipe for introducing the heat exchange medium and a lead-out pipe for leading out the heat exchange medium from the conduit are provided.

According to the present invention, it is possible to realize a fluid cooling device having high heat transfer efficiency. Other effects of the present invention will also be described in the section of embodiments for carrying out the following inventions.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals, so that duplicate description will be omitted.

In the present embodiment, as a fluid cooling device, a cooling medium is passed through a conduit, and the fluid is cooled by exchanging heat between the fluid and the cooling medium (heat exchange medium) via the conduit. An explanation will be given using the device as an example. Hereinafter, the details of the fluid cooling device according to the present embodiment will be described with reference to the drawings. First, the configuration of the fluid cooling device according to the present embodiment will be described with reference to FIGS. 1 to 4. As shown in FIGS. 1 and 2, the fluid cooling device 1 includes a container (sliding body) 10 provided with at least two handles 102 for accommodating the fluid, and the inner circumference of the container 10. The cooling unit 20 having a cooling pipe 202 for cooling the fluid, the cooling medium supply pipe 22 for introducing a cooling medium such as water or antifreeze into the cooling unit 20, and the cooling unit 20 are arranged. It is configured to include a cooling medium discharge pipe 24 for discharging the introduced cooling medium, and a flange portion 26 that can be attached to and detached from the container 10 that supports the cooling medium supply pipe 22 and the cooling medium discharge pipe 24. In FIG. 2, only the container 10, the handle 102, and the cooling pipe 202 are shown for easy understanding.

The cooling unit 20 is a cylindrical member arranged so as to immerse in a fluid material filled in the container 10, and as shown in FIG. 1, four flexible cooling units in which a cooling medium flows inside. The peripheral walls are formed by the pipes 202a to 202d (hereinafter, when they are not individually distinguished, they are referred to as cooling pipes 202). The cooling pipe 202 is a conduit having a circular cross section composed of a heat transfer member such as a metal such as stainless steel, titanium, copper, or aluminum, or an alloy, and has a surface having a predetermined shape, or a cylindrical surface in the present embodiment. It is bent along. In other words, the cooling pipe 202 is bent to form a cylindrical shape of the cooling unit 20. More specifically, a plurality of cooling pipes 202 are arranged in parallel on a substantially plane so as to be spaced apart from each other (for example, 5 mm), and are spirally wound together while maintaining this parallel state. .. Therefore, the cooling pipes 202 adjacent to each other in the vertical direction are cooling pipes 202 different from the self, for example, the cooling pipes 202a are interposed between the cooling pipes 202b to 202d as shown in FIGS. 1 and 2. It will be arranged at equal intervals in the vertical direction. This also applies to the other cooling pipes 202b to 202d.

The interval between the cooling pipes 202 described above can be appropriately set depending on how the cooling pipe 202 is wound, and may be adjusted according to the type of fluid or cooling medium, the required cooling capacity, and the like. Further, from the viewpoint of cooling efficiency, it is preferable that the cooling unit 20 is arranged at a predetermined interval from the inner wall of the container 10.

The cooling pipe 202 is provided with an introduction pipe 204 for introducing a cooling medium. More specifically, the cooling pipe 202a is provided with the introduction pipe 204a, the cooling pipe 202b is provided with the introduction pipe 204b, the cooling pipe 202c is provided with the introduction pipe 204c, and the cooling pipe 202d is provided with the introduction pipe 204d. .. Similarly, the cooling pipe 202 is provided with a lead-out pipe 206 for leading out the cooling medium. More specifically, the cooling pipe 202a is provided with the outlet pipe 206a, the cooling pipe 202b is provided with the outlet pipe 206b, the cooling pipe 202c is provided with the outlet pipe 206c, and the cooling pipe 202d is provided with the outlet pipe 206d. ..

The introduction pipe 204 is arranged inside the cooling unit 20 in the in-diameter direction with respect to the cooling pipe 202, one end thereof is connected to the cooling medium supply pipe 22, and the other end is located at the lower end of the cooling unit 20. It is connected to the cooling pipe 202. The outlet pipe 206 is arranged inside the cooling unit 20 in the in-diameter direction with respect to the cooling pipe 202, one end thereof is connected to the cooling medium discharge pipe 24, and the other end is located at the upper end of the cooling unit 20. It is connected to the cooling pipe 202. Therefore, the cooling medium supplied to the cooling medium supply pipe 22 is divided by each introduction pipe 204 and supplied to each cooling pipe 202 located at the lower end of the cooling unit 20, and the cooling medium spirals from the bottom to the top. It will flow. Further, the cooling medium that has flowed upward is supplied from each cooling pipe 202 to the outlet pipe 206, merges in the cooling medium discharge pipe 24, and is discharged to the outside. It is preferable that the introduction pipe 204 and the outlet pipe 206 are made of the same members as the cooling pipe 202.

According to such a cooling unit 20, since it is in contact with the fluid material over the entire circumference of the cooling pipe 202, as compared with the case where a cooling medium is arranged on the outer periphery of the container for accommodating the fluid material and cooled. The surface area of the cooling unit 20 in contact with the fluid is extremely large, and the cooling efficiency can be significantly improved.

Further, in the present embodiment, the same conduit is used for the cooling pipe 202, the introduction pipe 204, and the outlet pipe 206. As shown in FIGS. 3A and 3B, these conduits have a so-called bellows shape in which a valley portion 208a and a mountain portion 208b protruding outward from the valley portion 208a are continuously formed. I'm doing it. As a result, the cooling pipe 202, the introduction pipe 204, and the discharge pipe 206 have flexibility, and the surface area thereof can be expanded, which in turn enhances the cooling efficiency. The shape of these conduits is not limited to this. For example, a conduit having a flat surface on which the valley portion 208a and the peak portion 208b are not formed as shown in FIG. 3C may be used, but a semicircular or rectangular convex portion is provided on the outer surface thereof. It is preferable to use a conduit having a shape that can increase the surface area of each conduit. Further, different types of conduits may be used for the cooling pipe 202, the introduction pipe 204, and the outlet pipe 206. Reference numeral B shown in FIG. 3B indicates a cavity in the conduit, that is, a flow path through which the cooling medium flows.

Both the cooling medium supply pipe 22 and the cooling medium discharge pipe 24 are L-shaped conduits having one end protruding upward, and the end 222 protruding upward from the cooling medium supply pipe 22 supplies the cooling medium. The end 242 protruding upward from the cooling medium discharge pipe 24 is connected to various devices, containers, etc. for cooling, storing, or discarding the discharged cooling medium again. As a result, circulation of the cooling medium of the cooling unit 20 is realized.

As shown in FIGS. 1 and 4, a cooling medium supply pipe 22 and a cooling medium discharge pipe 24 are supported on the upper end edge of the container 10, and the outer periphery thereof has a ring shape protruding outward from the container 10. A flange portion 26, which is a flat plate member, is detachably provided. Therefore, by disconnecting the end 222 of the cooling medium supply pipe 22 and the end 242 of the cooling medium discharge pipe 24 and removing the flange 26 from the container 10, the cooling unit 20 is placed in the container via each conduit. It can be easily removed from 10. As a method of fixing the collar portion 26 to the container 10, a method of providing a concave portion on one side and a convex portion on the other side and fitting them, a method of fastening with screws, etc. are appropriate, and the collar portion 26 is fixed to the container 10. Any method is possible. The reference numeral C shown in FIG. 4 indicates a storage space in which a fluid substance is housed.

It is preferable to fix the cooling unit 20 to the container 10 so that the cylindrical shape formed by the cooling pipe 202 does not collapse. In the present embodiment, the pressing plates 30 are provided at four locations in the container 10 so as to sandwich the cooling portion 20 with the container 10 so as to face each other, and the cooling portion 20 is fixed to the container 10 in a pressing manner. There is. As shown in FIG. 1, the holding plate 30 is a rectangular plate-shaped member extending in the vertical direction, the upper end portion thereof is fixed to the container 10 by a fixture 302 composed of bolts and nuts, and the lower end portion is a cooling portion 20. It is inserted and sandwiched between the cooling pipe 202a located at the lower end of the container 10 and the bottom wall of the container 10. In this way, if the cooling unit 20 is pressed against the container 10 by the pressing plate 30 fixed by the simple fixing tool 302, the cooling unit 20 can be easily attached to and detached from the container 10.

When the fluid material cooling device 1 is actually used, the fluid material can be cooled only by filling the container 10 with the fluid material and then flowing the cooling medium through the cooling medium supply pipe 22. Here, as shown in FIG. 5, the fluid material cooling device 1 further includes a tubular cooler 40 that can be accommodated in the container 10, and the fluid material cooling device 1 is put into the fluid material to move up, down, left, and right. You may want to move and rotate in the direction. As a result, stirring can be performed together with cooling, and the cooling efficiency becomes higher. The cooler 40 includes a hollow cylindrical main body 402 that is immersed in a fluid, an introduction pipe 404 that injects a cooling medium into the main body 402, a discharge pipe 406 that discharges a cooling medium from the main body 402, and a main body 402. It is configured to include a connecting portion 408 for connecting the main body 402 to a driving device (not shown) to be displaced. The specific configuration and operation of the cooler 40 are the same as those described in "Japanese Patent Application No. 2013-273368" previously filed by Ryosan Industry Co., Ltd., the patent applicant of the present invention. Therefore, the description here is omitted.

According to the present embodiment, since the cooling pipe 202 is bent into a cylindrical shape to form the cooling portion 20, the surface of the cooling pipe 202 is uniformly in contact with the fluid, so that the cooling efficiency is very high, that is, high. It is possible to realize heat transfer efficiency, which in turn can shorten the cooling time. Further, by forming the cooling portion 20 by using the bellows-shaped cooling pipe 202, the surface area thereof can be expanded and higher cooling efficiency can be realized. Further, since the cooling unit 20 is formed by the plurality of cooling pipes 202, the time required for heat exchange between the cooling medium and the fluid is compared with the case where the cooling unit 20 is formed by one cooling pipe 202. Can be shortened and the cooling efficiency can be further improved. Further, since a gap is formed between the cooling pipes 202, the fluidity of the fluid is increased, and the temperature unevenness of the fluid is less likely to occur, which is a unique effect. Furthermore, since the cooling portion 20 is formed only by the bent cooling pipe 202, the cost is extremely low.

Further, in the present embodiment, it has been described that the cooling pipes 202 of the cooling unit 20 are wound and arranged so as to draw a spiral together while maintaining the parallel state, but the present invention is not limited to this. .. For example, as shown in FIG. 6, the cooling pipe 202a is continuously wound, and then the cooling pipe 202b is continuously wound so as to be concentric with the cooling pipe 202a, and the same applies to the cooling pipes 202c and 202d. The cooling unit 20a may be formed with. Even in such a form, it can have the same cooling capacity as the cooling unit 20.

In addition, as a method of forming the cooling unit 20, a plurality of cooling pipes 202 in a state of being arranged side by side at a predetermined interval on a substantially plane are arranged around, for example, meandering in the vertical direction along the surface of a cylinder. The cooling unit 20 may be formed by being provided. Further, for example, a hollow cylinder may be formed by twisting together four cooling pipes 202 in a state where the lower end portions connected to the introduction pipe 204 are arranged on all four sides of a circle in one direction.

Further, as shown in FIG. 7, a cooling portion having a small diameter is formed by the cooling pipe 202e to be used as the main body 502, and a cooler 50 having the main body 502 is realized and used together with the cooling portion 20. You may. That is, two cooling units 20 are prepared, the diameter of one cooling unit 20 is made smaller than the diameter of the other cooling unit 20, one cooling unit 20 is used as a cooler 50, and the other cooling unit 20 is used. In a state of being provided along the inner circumference of the container 10, the cooler 50 is inserted into the hollow of the cylinder formed by the other cooling unit 20 to cool the fluid. According to this, since the fluid can pass through the gap between the cooling pipes 202e during the stirring operation of the fluid, the temperature unevenness can be further suppressed as compared with the cooler 40 as shown in FIG. , Cooling efficiency can be improved. Although the main body 502 shown in FIG. 7 is formed by one cooling pipe 202e, it goes without saying that the main body 502 may be formed by a plurality of cooling pipes 202 as in the cooling unit 20 shown in FIG. ..

Further, in the present embodiment, the cooling units 20 and 20a and the cooler 50 have been described as hollow cylindrical shapes, respectively, but the present invention is not limited to this, and polygonal shapes and conical shapes may be used, and the shapes are appropriately used. Is. Further, the cooling units 20 and 20a and the cooler 50 may have a so-called multiple structure by arranging the cooling units 20 and 20a and the cooler 50 having different diameters in the hollow. By adopting a multiple structure, the cooling efficiency can be remarkably improved.

Further, in the present embodiment, the fluid cooling device 1 in which the cooling medium flows as the heat exchange medium in the cooling pipe 202 has been described as an example of the fluid cooling device, but the present invention is not limited to this. Absent. A fluid cooling device 1 is provided as a fluid heating device that heats a fluid by flowing a heating medium that is a fluid such as a high-temperature liquid or gas in the cooling pipe 202, that is, by using the cooling pipe 202 as a heating pipe. It is also possible to build. In this case as well, as in the fluid cooling device 1, since the area of the heating tube in contact with the fluid is extremely large, high heating efficiency, in other words, high heat transfer efficiency can be realized, and the fluid can be heated in a short time. be able to.
