Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a refrigeration device. Background Art

[0002] At present, some refrigeration equipment uses the heat exchange medium in the gravity heat pipe for cooling. In the relevant technology, there are two cooling methods of gravity heat pipe. The first is that the heat exchange medium at the top is condensed into liquid after heat exchange with the cold source, and flows to the bottom under its own gravity. During the flow, it absorbs heat in the box and evaporates to form a gas. The gaseous heat exchange medium returns to the top along the original route. However, this method is prone to blockage of the two forms of heat exchange medium, resulting in poor circulation. The second is that the gravity heat pipe is set as a closed-loop pipe. The heat exchange medium at the top is condensed into liquid after heat exchange with the cold source, and flows quickly to the bottom through a straight pipe section under its own gravity, then absorbs heat and evaporates, and returns to the top through another curved pipe section. However, the cooling area of ​​this method is concentrated at the bottom of the box, and the cooling effect is poor. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a refrigeration device that not only makes the flow of heat exchange medium smoother, but also makes the heat exchange area between the heat exchange medium and the liner more comprehensive and uniform, thereby improving the cooling effect.

[0004] According to an embodiment of the present invention, the refrigeration equipment includes a box body, a cold source and a gravity heat pipe. The box body has a box liner, the cold source is arranged in the box body, the gravity heat pipe is arranged in the box body, the gravity heat pipe is used to transport heat exchange medium, and the gravity heat pipe includes a condensation section and at least two heat absorption sections.

The heat absorption section is attached to the side wall of the box liner, and the heat absorption section has multiple bent pipe structures.

[0005] The refrigeration equipment according to the embodiment of the present utility model has at least the following beneficial effects:

[0006] The heat exchange medium in the condensing section absorbs the cold energy generated by the cold source and condenses to form a liquid. The liquid heat exchange medium flows to the bottom of the heat absorbing section under its own gravity. Since the heat absorbing section has multiple bends, the liquid heat exchange medium will then flow through the heat absorbing section more slowly to fully exchange heat with the tank. After absorbing heat, it evaporates to form a gas. The gaseous heat exchange medium is squeezed by the liquid heat exchange medium and flows back to the condensing section. This cycle repeats to cool the tank. The refrigeration equipment of the present invention has at least two heat absorbing sections because the gravity heat pipe is formed. Even if the heat exchange medium in one of the heat absorbing sections is temporarily blocked, the heat exchange medium can circulate through the other heat absorbing sections, and the heat exchange medium flows more smoothly. In addition, each heat absorbing section has multiple bends, and the liquid heat exchange medium can fully exchange heat with the tank when flowing through each heat absorbing section, and the heat exchange area is more comprehensive and uniform, thereby achieving a better cooling effect.

[0008] According to some embodiments of the present invention, a straight tube structure is formed between two adjacent curved tube structures in the heat absorption section, and the straight tube structure extends downwardly from the top end to the bottom end of the heat absorption section.

[0009] According to some embodiments of the present invention, the straight tube structure has a downwardly inclined angle of θ, which satisfies the following: 5°≤θ≤10°.

[0010] According to some embodiments of the present invention, part of the curved pipe structure is located at a corner between two adjacent side walls of the box, and the straight pipe structures connected to both ends of the curved pipe structure are respectively attached to two adjacent side walls of the box.

[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of this utility model, "a plurality" refers to two or more. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] At present, some refrigeration equipment uses the heat exchange medium in the gravity heat pipe for cooling. Compared with the traditional method of transferring cooling capacity through fans, there is no need to set up fans, process complex air ducts, or have corresponding control programs to control the operation of fans. The structure is relatively simple and the cost is low. In addition, there is no need to consider the situation where the fan is easily damaged when the cooling temperature is too low, for example, when the cooling temperature is below minus 50 degrees.

[0034] In the related art, there are two main cooling methods of gravity heat pipes. The first is that one end of the gravity heat pipe extends to the top of the box and is connected to the cold source, and the other end of the gravity heat pipe extends to the bottom of the box. The gravity heat pipe has a curved pipe structure. The heat exchange medium at the top of the gravity heat pipe condenses into liquid after heat exchange with the cold source, and flows to the bottom under its own gravity. During the flow, it absorbs heat in the box and evaporates to form a gas. The gaseous heat exchange medium flows back to the top along the original route. However, this method is prone to temporary blockage of the two forms of heat exchange medium in some areas of the gravity heat pipe, resulting in poor flow.

[0035] The second type is that the gravity heat pipe is set as a closed-loop pipe. The top of the gravity heat pipe is connected to the cold source. The gravity heat pipe includes a vertical section and a curved section. The heat exchange medium condenses into liquid after exchanging heat with the cold source. It quickly passes through the vertical section under its own gravity and flows to the bottom end. Then it flows back to the top through the curved section. It absorbs heat and evaporates when flowing through the curved section. Although this method can reduce the blockage, due to gravity, the liquid heat exchange medium can only gather at the bottom end of the curved section, resulting in the refrigeration area concentrated at the bottom end of the box, and the refrigeration effect is poor.

[0036] Therefore, the present invention proposes a refrigeration device, which can effectively improve the above problems.

[0037] Reference below Figures 1 to 6 The following describes a refrigeration device according to an embodiment of the present invention.

[0038] According to the refrigeration equipment of the embodiment of the present utility model, Figures 1 to 5 As shown, it includes a box 100, a cold source 200 and a gravity heat pipe 300.

[0039] Among them, reference Figure 1 、 Figure 2 as well as Figure 5 As shown, the housing 100 is the overall support structure of the refrigeration device, and the cold source 200 and the gravity heat pipe 300 are installed in the housing 100. In addition, other components of the refrigeration device, such as a controller, may also be installed in the housing 100. The housing 100 may include a housing 101 and a housing shell 103. The housing 101 may be arranged within the housing shell 103. The housing 101 may be formed with a storage cavity, which may be open at the front and used to store food or other items. In some embodiments of the present invention, the refrigeration device may be a refrigerator, a fresh-keeping cabinet, a freezer, etc.

[0040] refer to Figure 1 and Figure 2 As shown, the cold source 200 is provided in the box body 100. For example, the cold source 200 can be installed at the top of the box shell 103 of the box body 100. The cold source 200 can be a refrigeration evaporator. The cold source 200 can also be a refrigerator, such as a Stirling refrigerator. The cold source 200 is used to generate cold energy.

[0041] refer to Figures 1 to 4As shown, the gravity heat pipe 300 is provided in the housing 100 and is used to transport the heat exchange medium 400. For example, the gravity heat pipe 300 may include a condensing section 301, which is connected to the cold source 200. For example, the condensing section 301 may be snap-fitted, threaded, or welded to the cold source 200. The gravity heat pipe 300 may further include at least two heat absorbing sections 302, for example, there may be two, three, four or other suitable number of heat absorbing sections 302, the bottom ends of at least two heat absorbing sections 302 being connected, so that any two heat absorbing sections 302 are connected, and the heat exchange medium 400 can flow from one heat absorbing section 302 to another heat absorbing section 302, and the top end of the heat absorbing section 302 is connected to the condensing section 301, so that the heat exchange medium 400 in the condensing section 301 can flow through the heat absorbing section 302 after condensation and flow to the bottom end of the heat absorbing section 302, and the heat exchange medium 400 at the bottom end of the heat absorbing section 302 can evaporate and flow back to the condensing section 301 through the heat absorbing section 302. The heat absorbing section 302 is attached to the side wall of the casing 101 of the housing 100. For example, the heat absorbing section 302 may be entirely attached to the side wall of the casing 101, or only partially attached to the side wall of the casing 101. The heat absorbing section 302 may be attached to the outer surface of the side wall of the casing 101, or to the inner surface of the side wall of the casing 101, to facilitate heat exchange with the casing 101. The heat absorbing section 302 has a plurality of curved pipe structures 303, the number of which is set according to actual needs. The curved pipe structures 303 can slow the flow of the liquid heat exchange medium 400 and, if the height difference between the top end and the bottom end of the heat absorbing section 302 is constant, can increase the length of the heat absorbing section 302.

[0042] It is understandable that the gravity heat pipe 300 can be a round tube or other suitable shapes, for example, an elliptical tube, etc. In addition, the gravity heat pipe 300 can be a copper tube, an aluminum tube, a steel tube or other tubes made of materials with low heat transfer coefficients, which will not be described in detail here.

[0043] Among them, the heat exchange medium 400 in the condensing section 301 absorbs the cold energy generated by the cold source 200 and condenses to form a liquid. Since the bottom end of the heat absorbing section 302 is located below the condensing section 301, the liquid heat exchange medium 400 will flow through the heat absorbing section 302 under its own gravity and flow to the bottom end of the heat absorbing section 302. Since the heat absorbing section 302 has multiple curved pipe structures 303, the curved pipe structures 303 can not only slow down the flow speed of the liquid heat exchange medium 400, so that the heat exchange medium 400 flows for a longer time and thus absorbs heat for a longer time, but also, when the height difference between the top end of the heat absorbing section 302 and the bottom end of the heat absorbing section 302 is constant, the heat absorbing section 302 can be made longer, so that the heat exchange medium 400 flows for a longer time and flows over a wider range, so that the heat absorption time and the heat absorption range are longer, so that the liquid heat exchange medium 400 can fully exchange heat with the box 101, and the heat exchange area is more comprehensive and uniform. After absorbing heat, the liquid heat exchange medium 400 evaporates to form a gas. The gaseous heat exchange medium 400 is squeezed by the liquid heat exchange medium 400 and flows back to the condensing section 301. This cycle repeats to cool the chamber 101. It should be noted that the heat exchange medium 400 can be of various types, such as ethane, carbon dioxide, or other suitable types. It only needs to be able to condense and evaporate within the required temperature range, and will not be described in detail here.

[0044] The refrigeration equipment of the present invention can cool down by setting up a gravity heat pipe 300, without the need for additional fans or other driving components for driving the transfer of cold, nor does it need to set up a complex air duct structure, nor does it need to control the operation of the fan through a control program. The structure is simpler and the cost is lower. Moreover, even if the cooling temperature is low, there is no possibility of fan damage, and the reliability is better. Correspondingly, since there is no need to consider the possibility of fan damage, the minimum cooling temperature of the refrigeration equipment can be greatly reduced, such as Figure 6 As shown, after the refrigeration device of the present invention has been running for a period of time, the temperature in the storage cavity of the box 101 can be reduced to nearly minus 100 degrees. In addition, since the gravity heat pipe 300 is formed with at least two heat-absorbing sections 302, even if the liquid heat exchange medium 400 and the gaseous heat exchange medium 400 are temporarily blocked in one of the heat-absorbing sections 302, the heat exchange medium 400 can flow through the other heat-absorbing sections 302, making the flow of the heat exchange medium 400 smoother. In addition, each heat-absorbing section 302 has multiple bend structures 303, so that the liquid heat exchange medium 400 can fully exchange heat with the box 101 when flowing through each heat-absorbing section 302, and the heat exchange area is more comprehensive and uniform, thereby achieving a better cooling effect of the refrigeration device.

[0045] refer to Figure 3As shown, in some embodiments of the present invention, the curved tube structure 303 is arc-shaped, and the radius of curvature of the axis of the curved tube structure 303 is R. That is, the distance between the axis of the curved tube structure 303 and the center of curvature of the axis is R, and the outer diameter of the heat absorbing section 302 is d, such that R ≥ 2d. For example, the value of the radius of curvature R of the axis of the curved tube structure 303 can be 2 times, 3 times, 4 times, or other suitable multiples of the value of the outer diameter d of the heat absorbing section 302.

[0046] In this embodiment, such a setting can prevent the heat exchange medium 400 from encountering excessive local resistance when flowing to the curved pipe structure 303, thereby hindering the flow of the heat exchange medium 400, thereby making the heat exchange medium 400 flow smoother and the cold transfer smoother, thereby making the cooling effect of the refrigeration equipment better.

[0047] It should be noted that, when the condensation section 301 also has a curved pipe structure 303 , the curvature radius of the axial centerline of the curved pipe structure 303 of the condensation section 301 may also be twice or more than twice the outer diameter of the condensation section 301 .

[0048] refer to Figures 2 to 4 As shown, in some embodiments of the present invention, a straight tube structure 304 is formed between two adjacent curved tube structures 303 in the heat absorbing section 302. The straight tube structure 304 extends downwardly and obliquely from the top of the heat absorbing section 302 to the bottom of the heat absorbing section 302. For example, the heat absorbing section 302 may include multiple curved tube structures 303 and multiple straight tube structures 304. The curved tube structures 303 and the straight tube structures 304 may be arranged in a staggered manner. A straight tube structure 304 is formed between two adjacent curved tube structures 303. The straight tube structure 304 extends downwardly and obliquely from the top of the heat absorbing section 302 to the bottom of the heat absorbing section 302, that is, extends downwardly and obliquely relative to the horizontal plane along the flow direction of the liquid heat exchange medium 400.

[0049] In this embodiment, the other parts of the heat absorbing section 302 except the bend structure 303 can be a straight tube structure 304 inclined downward. In this way, it is not only convenient for the liquid heat exchange medium 400 to flow downward by its own gravity, and thus facilitates the heat exchange medium 400 to flow through the bend structure 303 more smoothly. In addition, compared with vertically arranging the pipe section of the heat absorbing section 302 except the bend structure 303, this embodiment is set to an inclined straight tube structure 304, so that the liquid heat exchange medium 400 will not flow too fast in the pipe section except the bend structure 303, and at the top of the heat absorbing section 302 When the height difference between the upper end and the bottom end of the heat absorption section 302 is constant, the heat absorption section 302 can be made longer, thereby making the heat exchange medium 400 flow longer and flow range wider, thereby making the heat absorption time longer and the heat absorption range wider, thereby making the refrigeration effect of the refrigeration equipment better. In addition, it is convenient for the gaseous heat exchange medium 400 to flow in the area above the liquid heat exchange medium 400, thereby further reducing the blockage of the gaseous heat exchange medium 400 and the liquid heat exchange medium 400, making the heat exchange medium 400 flow smoother, thereby making the refrigeration effect of the refrigeration equipment better.

[0050] It should be noted that in some other embodiments of the present invention, one or both ends of some curved tube structures 303 may not be formed with inclined straight tube structures 304 but may be vertically arranged, which will not be described in detail here.

[0051] refer to Figure 3 As shown, in a further embodiment of the present invention, the angle at which the straight tube structure 304 is tilted downward is θ, satisfying the following: 5°≤θ≤10°. The angle at which the straight tube structure 304 is tilted downward can be 5°, 6°, 7°, 8°, 9°, 10°, or other suitable degrees, for example, 7°. In this embodiment, the angle at which the straight tube structure 304 is tilted downward is within a suitable range of 5° to 10°. This not only prevents the straight tube structure 304 from tilting too much, which would cause the liquid heat exchange medium 400 to flow too fast and thus shorten the heat absorption time, but also prevents the straight tube structure 304 from tilting too much, which would cause the heat absorption section 302 to be too short and thus shorten the heat absorption time, thereby reducing the cooling effect of the refrigeration device. In addition, it also prevents the straight tube structure 304 from tilting too little, which would affect the flow of the liquid heat exchange medium 400 and thus affect the cooling effect of the refrigeration device.

[0052] refer to Figure 2 As shown, in a further embodiment of the present invention, part of the curved tube structure 303 is located at the corner between two adjacent side walls of the box 101, and the straight tube structures 304 connected to both ends of the curved tube structure 303 are respectively attached to the two adjacent side walls of the box 101.

[0053] For example, among the multiple curved tube structures 303 of the same heat absorption section 302, one of the two adjacent curved tube structures 303 may be located at the corner between two adjacent side walls of the box 101, and the two straight tube structures 304 connected to the curved tube structure 303 located at the corner between two adjacent side walls of the box 101 are respectively fitted with two adjacent side walls of the box 101, and among the two straight tube structures 304, one straight tube structure 304 extends downwardly in a direction close to the curved tube structure 303, and the other straight tube structure 304 extends downwardly in a direction away from the curved tube structure 303, and thus the two curved tube structures 303 adjacent to the curved tube structure 303 located at the corner between two adjacent side walls of the box 101 can also be respectively fitted with two adjacent side walls of the box 101.

[0054] In this embodiment, the partial curved tube structure 303 of the heat absorbing section 302 is located at the corner between two adjacent side walls of the liner 101, and the two straight tube structures 304 connected to the curved tube structure 303 are respectively attached to the two adjacent side walls of the liner 101. This arrangement not only makes the contact range between the heat absorbing section 302 and the liner 101 wider and more uniform, thereby improving the cooling effect of the refrigeration device. In addition, the curved tube structure 303 at the corner of the liner 101 is not too curved, and the bending angle is greater than 90 degrees. This allows the liquid heat exchange medium 400 to pass through the curved tube structure 303 more smoothly, thereby improving the cooling effect of the refrigeration device.

[0055] It should be noted that, in some other embodiments of the present invention, the heat absorption section 302 may also be integrally bonded to the outer surface of one of the side walls of the box 101 .

[0056] refer to Figure 2 As shown, in a further embodiment of the present invention, the rear side of the box 101 has a rear side wall 102, wherein the partial curved pipe structure 303 of one heat absorption section 302 is located at the corner of one side of the rear side wall 102, and the partial curved pipe structure 303 of the other heat absorption section 302 is located at the corner of the other side of the rear side wall 102.

[0057] For example, the front side of the box 101 can be open to facilitate taking items from and placing items in the box 101. The partial curved tube structure 303 of one heat absorption section 302 can be located at the left corner of the rear side wall 102, and the two straight tube structures 304 connected to these curved tube structures 303 can be respectively attached to the left side wall and the rear side wall 102 of the box 101. The partial curved tube structure 303 of another heat absorption section 302 can be located at the right corner of the rear side wall 102, and the two straight tube structures 304 connected to these curved tube structures 303 can be respectively attached to the right side wall and the rear side wall 102 of the box 101.

[0058] In this embodiment, such a configuration enables the heat absorption section 302 to exchange heat with the box 101 from the left and right sides and the rear side of the box 101, resulting in a better heat exchange effect, thereby improving the cooling effect of the refrigeration equipment. In addition, it can also prevent the gravity heat pipe 300 from being too close to the open opening on the front side of the box 101, and when the box door is opened to take out items, it can reduce the heat exchange between the external environment and the heat exchange medium 400 in the gravity heat pipe 300 and affect the cooling effect, thereby improving the cooling effect.

[0059] refer to Figure 1 、 Figure 2 and Figure 5 As shown, in some embodiments of the present invention, the housing 100 further includes a housing shell 103, the housing 101 is disposed within the housing shell 103, and the heat absorbing section 302 is attached to the outer surface of the side wall of the housing 101. For example, the housing 101 may have a square structure, the housing shell 103 may have a square frame structure and be sleeved around the outer periphery of the housing 101, and the heat absorbing section 302 is located between the outer side wall of the housing 101 and the inner side wall of the housing shell 103. The heat absorbing section 302 is attached to the outer side wall of the housing 101 and may be fixed to the side wall of the housing 101 by welding or clamps.

[0060] In this embodiment, the housing 103 is configured in this manner to protect the liner 101 and the heat absorbing section 302, preventing them from being exposed to the outside and potentially damaging them. Furthermore, the housing 103 can be made of a heat-insulating material, thereby insulating the heat absorbing section 302 from the external environment, preventing heat exchange between the external environment and the heat absorbing section 302 and thereby affecting the cooling effect of the refrigeration device. Furthermore, the heat absorbing section 302 is attached to the outer surface of the side wall of the liner 101 and does not occupy space within the storage cavity of the liner 101.

[0061] refer to Figure 5 As shown, in some embodiments of the present invention, a heat insulating layer 104 is provided between the liner 101 and the housing 103. For example, the heat insulating layer 104 can be made of a heat insulating material such as heat insulating cotton or polyurethane foam. The heat insulating layer 104 can be filled between the side walls of the liner 101 and the side walls of the housing 103, or between the top plate of the liner 101 and the top plate of the housing 103, and between the bottom plate of the liner 101 and the bottom plate of the housing 103. In this embodiment, the provision of the heat insulating layer 104 can further prevent the external environment from exchanging heat with the heat exchange medium 400 in the gravity heat pipe 300 and affecting the cooling effect of the refrigeration device, thereby improving the cooling effect of the refrigeration device.

[0062] refer to Figure 1 and Figure 2As shown, in some embodiments of the present invention, the cold source 200 is located above the chamber 101, and the bottom end of the heat absorbing section 302 extends to the bottom end of the chamber 101. In this embodiment, such a configuration can maximize the height difference between the cold source 200 and the bottom end of the heat absorbing section 302, thereby further facilitating the liquid heat exchange medium 400 in the condensing section 301 to flow to the bottom end of the heat absorbing section 302 under the action of its own gravity.

[0063] refer to Figure 2 As shown, in some embodiments of the present invention, the heat absorbing sections 302 include two, and the gravity heat pipe 300 is configured as a closed loop. That is, the gravity heat pipe 300 is connected end to end, and the condensing section 301 is a single one. This allows the heat exchange medium 400 to flow more smoothly, thereby improving the cooling effect of the refrigeration equipment.

[0064] It should be noted that when there are two heat absorption sections 302, in some other embodiments of the present invention, the gravity heat pipe 300 may not be a closed-loop pipeline, and the two ends of the gravity heat pipe 300 in the longitudinal direction respectively form condensation sections 301. In this way, the processing is more convenient, and it is also more convenient to load and replace the heat medium 400.

[0065] refer to Figure 2 As shown, in some embodiments of the present invention, one or more connecting sections 305 are provided between the bottom ends of any two heat absorbing sections 302, and communication is achieved through the connecting sections 305. For example, one connecting section 305 can be provided between the bottom ends of any two heat absorbing sections 302, and communication is achieved through the connecting section 305. This structure is relatively simple. Of course, multiple connecting sections 305 can also be provided between the bottom ends of any two heat absorbing sections 302, and communication is achieved through the multiple connecting sections 305. In this way, when a temporary blockage occurs between the liquid heat exchange medium 400 and the gaseous heat exchange medium 400 in one of the connecting sections 305, the heat exchange medium 400 can also flow through other connecting sections 305, thereby improving the fluidity of the heat exchange medium 400 and thus improving the cooling effect of the refrigeration equipment.

[0066] refer to Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the highest point of the condensing section 301 is connected to the cold source 200. For example, the cold source 200 may be provided with a cooling member 201, which is used to transfer the cold energy generated by the cold source 200 to the condensing section 301, and the highest point of the condensing section 301 may be connected to the cooling member 201.

[0067] In this embodiment, the highest point of the condensation section 301 is connected to the cold source 200. When the heat exchange medium 400 in the condensation section 301 exchanges heat with the cold source 200 and condenses to form a liquid, it will not flow upward, and the flow will be smoother, thereby improving the cooling effect of the refrigeration equipment.

[0068] refer to Figure 2 As shown, in some embodiments of the present invention, the end of the condensing section 301 near the heat absorbing section 302 extends vertically. For example, the condensing section 301 can include three parts. The part of the condensing section 301 near the cold source 200 can be arranged horizontally, the part of the condensing section 301 near the heat absorbing section 302 can be arranged vertically, and the middle part of the condensing section 301 can be arranged at an angle. In this embodiment, the end of the condensing section 301 near the heat absorbing section 302 extends vertically. In this way, before the liquid heat exchange medium 400 in the condensing section 301 flows into the heat absorbing section 302, it will flow vertically downward for a distance. Then, the liquid heat exchange medium 400 will generate a certain impact force under the action of its own inertia, which is more conducive to the liquid heat exchange medium 400 flowing through the curved pipe structure 303 of the heat absorbing section 302, thereby making the liquid heat exchange medium 400 flow more smoothly, thereby improving the cooling effect of the refrigeration equipment.

[0069] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
