Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a transition device suitable for connecting a refrigeration machine and a refrigeration equipment. Background Technology

[0002] A refrigeration machine is a device that uses mechanical or thermodynamic principles to lower the temperature of a specific space or object below the ambient temperature and maintain it at a set low temperature. Refrigeration machines typically operate at extremely low temperatures. To improve the cooling effect on the target object, the primary and secondary components of the refrigeration machine are usually connected to the interior of the target object.

[0003] However, when the refrigeration unit needs repair or maintenance, it is necessary to separate the primary and secondary components of the refrigeration unit from the target cooling point. This connection method increases the difficulty of disassembling and assembling the refrigeration unit and the target cooling point, thus reducing the efficiency of disassembly and assembly during repair and maintenance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide a transitional device that can improve the disassembly and assembly efficiency during the maintenance and repair of refrigeration machines.

[0005] This application provides a transition device suitable for connecting a refrigeration unit and a refrigeration equipment. The transition device is at least partially located within the refrigeration equipment and includes a receiving element, an elastic tube, a fixed seat, and multiple adjusting rod assemblies. The receiving element has a cavity formed within it, capable of accommodating at least a portion of the refrigeration unit, and is also detachably connected to the refrigeration equipment. One end of the elastic tube is connected to the receiving element and communicates with the cavity, and the elastic tube is capable of accommodating at least a portion of the refrigeration unit. The fixed seat is connected to the other end of the elastic tube. Multiple adjusting rod assemblies are connected between the receiving element and the fixed seat, and each adjusting rod assembly can adjust a portion of the length of the elastic tube between the receiving element and the fixed seat.

[0006] In one possible implementation, the surface of the mounting base near the elastic tube is at least partially located inside the elastic tube. The surface of the mounting base located inside the elastic tube is defined as the cooling contact surface, which is used to contact the cooling part of the refrigerator. Each adjusting rod group adjusts the contact area between the cooling contact surface and the cooling part by adjusting the local length of the elastic tube.

[0007] In one possible implementation, each adjusting rod assembly includes a connecting rod, a fastener, and a locking element. One end of the connecting rod is connected to a receiving element; the fastener passes through a fixed seat and is connected to the other end of the connecting rod; the locking element is threadedly connected to the fastener and is located at at least one end of the fastener that passes through the fastener.

[0008] In one possible implementation, the accommodating member includes an accommodating portion having an accommodating cavity, a first connecting portion for connecting a refrigeration device and a refrigeration unit, and a second connecting portion for connecting to an elastic tube, with the first and second connecting portions located on opposite sides of the accommodating portion.

[0009] In one possible implementation, the second connecting portion is formed with a support protrusion for supporting the refrigerator, the support protrusion being located within the accommodating cavity; the support protrusion is formed with a cooling surface for contacting the cooling section of the refrigerator.

[0010] In one possible implementation, the transition device further includes a connecting flange fitted onto the receiving portion, the connecting flange being connected to the side of the first connecting portion near the second connecting portion, and the connecting flange also being used to connect the refrigeration equipment, so that the first connecting portion and the refrigeration equipment are detachably connected via the connecting flange.

[0011] In one possible implementation, a first heating element for heating the second connecting part is installed in the second connecting part, and a second heating element for heating the fixed base is installed in the fixed base, so that the first heating element and the second heating element can heat the refrigerator.

[0012] In one possible implementation, multiple first heating elements are provided, and the multiple first heating elements are inserted vertically into the second connecting part; the multiple first heating elements are evenly arranged around the receiving part; multiple second heating elements are provided, and the multiple second heating elements are inserted horizontally into the fixing base; the multiple second heating elements are evenly arranged around the elastic tube.

[0013] In one possible implementation, a first temperature sensor for detecting the temperature of the first heating element is also installed in the second connecting part, and a second temperature sensor for detecting the temperature of the second heating element is also installed in the fixing base.

[0014] The first temperature sensor is inserted vertically into the second connecting part, and the second temperature sensor is connected to the fixed base.

[0015] In one possible implementation, the transition device further includes a plurality of parallel members, each of which includes a first parallel surface and a second parallel surface that are parallel to each other. Each parallel member is located between the second connecting part and the fixed base. Each first parallel surface abuts against the side surface of the second connecting part near the fixed base, and each second parallel surface abuts against the side surface of the fixed base near the second connecting part.

[0016] The aforementioned transition device can accommodate the refrigeration unit through interconnected accommodating parts and flexible tubes, and connect the accommodating parts to the refrigeration equipment, so that the transition device can connect the refrigeration unit and the refrigeration equipment. This allows the refrigeration unit and the refrigeration equipment to be disassembled and assembled by removing and installing the transition device during the maintenance and repair of the refrigeration unit, thereby improving the efficiency of disassembly and assembly during the maintenance and repair of the refrigeration unit.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in specific embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

Similarly, "a" or "one," and similar terms do not indicate a quantity limitation, but rather indicate the presence of at least one. "A plurality" or "several" indicates at least two. Unless otherwise stated, terms such as "front," "back," "left," "right," "lower," and / or "upper" are for illustrative purposes only and are not limited to a location or spatial orientation.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0023] The singular forms “a,” “the,” and “the” used in this application specification and appended claims may also include one or more, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein describes the relationship between related objects, indicating that three relationships may exist, for example, A and / or B, which can represent: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural.

[0024] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The upper and lower parts are shown to indicate the upper and lower parts of the transition device 100.

[0025] In this application, the refrigerator 300 includes a primary refrigeration section 31 and a secondary refrigeration section 32. Through the primary refrigeration section 31 and the secondary refrigeration section 32, multi-stage refrigeration can be performed on the target to be cooled, thereby improving the cooling effect of the refrigerator 300 on the target. Furthermore, the cooling effect of the secondary refrigeration section 32 is greater than that of the primary refrigeration section 31. The refrigeration equipment is the target to be cooled in this application. The refrigerator 300 cools the refrigeration equipment so that it operates at the required temperature, thereby improving the working efficiency of the refrigeration equipment.

[0026] For example, in this application, the cooling device can be a superconducting magnet in a semiconductor single crystal furnace. A superconducting magnet can control melt convection during the growth of single crystal silicon by applying a strong magnetic field. The temperature of the superconducting magnet affects the strength of the magnetic field it generates; therefore, the superconducting magnet requires a low ambient temperature to operate normally. The superconducting magnet can be cooled by a refrigerator 300, allowing it to operate in a low-temperature environment, which helps to increase the magnetic field strength of the superconducting magnet, thereby improving the production efficiency and quality of single crystal silicon.

[0027] like Figure 1 and Figure 2 As shown, this application embodiment provides a transition device 100, which is suitable for connecting a refrigerator 300 and a refrigeration equipment. The transition device 100 is at least partially located inside the refrigeration equipment and includes a receiving member 11, an elastic tube 12, a fixed base 13, and a plurality of adjusting rod groups 14.

[0028] The accommodating member 11 is detachably connected to the refrigeration equipment, and the accommodating member 11 can accommodate at least a portion of the refrigeration unit 300. Specifically, the accommodating member 11 has a accommodating cavity 111 formed therein, capable of accommodating at least a portion of the refrigeration unit 300. In some embodiments, the accommodating member 11 is detachably connected to the refrigeration equipment by bolts.

[0029] The flexible tube 12 is connected to the receiving member 11, and the flexible tube 12 can accommodate at least a portion of the refrigerator 300. Specifically, one end of the flexible tube 12 is connected to the receiving member 11 and communicates with the receiving cavity 111, so that the flexible tube 12 can accommodate at least a portion of the refrigerator 300.

[0030] The fixing seat 13 is connected to the elastic tube 12, and the fixing seat 13 is used to fix the position of the elastic tube 12. Specifically, the fixing seat 13 is connected to the other end of the elastic tube 12, that is, the end of the elastic tube 12 away from the receiving member 11 is connected to the fixing seat 13.

[0031] In some embodiments, the two ends of the elastic tube 12 are welded to the receiving member 11 and the fixing seat 13, respectively. A plurality of adjusting rod assemblies 14 are connected to the receiving member 11 and the fixing seat 13, respectively. The plurality of adjusting rod assemblies 14 are used to adjust the distance between the receiving member 11 and the fixing seat 13, so that the plurality of adjusting rod assemblies 14 can adjust the length of the elastic tube 12 between the receiving member 11 and the fixing seat 13. Specifically, the plurality of adjusting rod assemblies 14 are all connected between the receiving member 11 and the fixing seat 13, and each adjusting rod assembly 14 can adjust the local length of the elastic tube 12 between the receiving member 11 and the fixing seat 13.

[0032] With the above configuration, the receiving component 11, the elastic tube 12, the fixing seat 13, and the multiple adjusting rod assemblies 14 can connect and fix the refrigeration unit 300 and the refrigeration equipment, that is, the transition device 100 can connect and fix the refrigeration unit 300 and the refrigeration equipment. Furthermore, by disassembling and assembling the transition device 100, the refrigeration unit 300 and the refrigeration equipment can be disassembled and assembled, thereby improving the efficiency of disassembling and assembling the refrigeration unit 300 during maintenance and repair.

[0033] Furthermore, in the above configuration, the distance between the receiving member 11 and the fixed base 13 in the vertical direction of the transition device 100 can be adjusted by the adjusting rod assembly 14. This allows the length of the elastic tube 12 disposed between the fixed base 13 and the receiving member 11 to be adjusted, so that the length of the elastic tube 12 can be adjusted according to the length of the secondary refrigeration section 32. This allows the elastic tube 12 to accommodate secondary refrigeration sections 32 of different lengths, thereby improving the compatibility of the elastic tube 12 with refrigeration units 300 of different sizes. At the same time, multiple adjusting rod assemblies 14 can ensure that the length of the elastic tube 12 at different positions is adapted to the corresponding secondary refrigeration section 32, thereby facilitating the elastic tube 12 to accommodate the secondary refrigeration section 32.

[0034] For example, in this application, the elastic tube 12 can be a bellows. By adjusting the length of the multiple adjusting rod groups 14, the distance between the fixing seat 13 and the receiving member 11 can be adjusted, thereby adjusting the length of the bellows disposed between the fixing seat 13 and the receiving member 11, so that the bellows can accommodate secondary refrigeration sections 32 of different lengths.

[0035] It should be noted that as long as the elastic tube 12 can be adjusted in length to accommodate secondary refrigeration sections 32 of different lengths, this application does not impose any restrictions on the material or shape of the elastic tube 12.

[0036] It should be noted that in this application, the accommodating cavity 111 contains at least a portion of the primary refrigeration section 31, and the elastic tube 12 contains at least a portion of the secondary refrigeration section 32, so that the transition device 100 can accommodate at least a portion of the refrigeration unit 300. This allows the primary refrigeration section 31 and the secondary refrigeration section 32 to be disassembled and assembled when the accommodating component 11 and the elastic tube 12 are disassembled and assembled, and the refrigeration unit 300 and refrigeration equipment can be disassembled and assembled when the accommodating component 11 and the elastic tube 12 are disassembled and assembled, thereby improving the disassembly and assembly efficiency of the refrigeration unit 300 during maintenance and repair.

[0037] In summary, the accommodating member 11 accommodates at least a portion of the refrigeration unit 300 and is connected to the refrigeration equipment. The elastic tube 12 is connected to the accommodating member 11 and accommodates at least a portion of the refrigeration unit 300, so that the transition device 100 can connect the refrigeration unit 300 and the refrigeration equipment. This allows the refrigeration unit 300 to be disassembled and assembled with the transition device 100 during maintenance and repair, thereby improving the efficiency of disassembly and assembly during maintenance and repair of the refrigeration unit 300.

[0038] In one embodiment, the surface of the fixing seat 13 near the elastic tube 12 is at least partially located inside the elastic tube 12, that is, the upper surface of the fixing seat 13 in the vertical direction of the transition device 100 is at least partially located inside the elastic tube 12. The surface of the fixing seat 13 located inside the elastic tube 12 is defined as the cold-conducting contact surface 131. The cold-conducting contact surface 131 is used to contact the refrigeration section (i.e., the secondary refrigeration section 32) of the refrigerator 300. Each adjusting rod assembly 14 adjusts the local length of the elastic tube 12 to adjust the contact area between the cold-conducting contact surface 131 and the refrigeration section. Since the contact area between the cold-conducting contact surface 131 and the refrigeration section affects the refrigeration effect of the refrigerator 300, in the above arrangement, the local length of the elastic tube 12 at different positions can be adjusted by multiple adjusting rod assemblies 14, thereby making the lower surface of the elastic tube 12 fit more closely to the upper surface of the fixing seat 13, which helps to increase the contact area between the upper surface of the fixing seat 13 and the cold-conducting contact surface 131, thus improving the refrigeration effect of the refrigerator 300 on the fixing seat 13.

[0039] For example, in this application, a secondary indium sheet of the refrigerator 300 can be provided at the connection between the cold-conducting contact surface 131 and the cooling unit, that is, a secondary indium sheet of the refrigerator 300 can be provided at the connection between the upper surface of the fixing base 13 and the cooling unit. The secondary indium sheet of the refrigerator 300 is a component with high heat insulation effect. Through the above arrangement, heat transfer between the refrigerator 300 and the external environment can be isolated, so as to avoid the heat of the external environment from interfering with the cooling efficiency of the refrigerator 300, thereby improving the cooling effect of the refrigerator 300.

[0040] In one embodiment, each adjusting rod assembly 14 includes a connecting rod 141, a fastener 142, and a locking element 143.

[0041] The connecting rod 141 is the main structure of the adjusting rod assembly 14 and is used to connect the fixed base 13 and the receiving part 11.

[0042] Fastener 142 is used to fix the relative position of each connecting rod 141 and the fixing seat 13.

[0043] The locking member 143 is used to fix the fastener 142 and the fixing seat 13, and cooperates with the fastener 142 and the connecting rod 141 to adjust the distance between the fixing seat 13 and the receiving member 11.

[0044] In this embodiment, one end of the connecting rod 141 is connected to the receiving member 11. The fastener 142 passes through the fixing base 13 and is connected to the other end of the connecting rod 141. The locking member 143 is threadedly connected to the fastener 142, and the locking member 143 is located at at least one end of the fastener 142 through which the fastener 142 passes.

[0045] In the above configuration, when the locking member 143 connects the fastener 142 and the fixed seat 13, rotating the locking member 143 can adjust the length of the part of the fastener 142 between the second connecting part 114 and the fixed seat 13 in the vertical direction of the transition device 100. This allows the distance between the fixed seat 13 and the accommodating member 11 in the vertical direction of the transition device 100 to adjust the length of the elastic tube 12, thereby facilitating the elastic tube 12 to accommodate secondary refrigeration sections 32 of different lengths.

[0046] For example, the locking element 143 can be a nut, and the fastener 142 can be a bolt. The bolt passes through the nut and the fixing seat 13 and connects to the corresponding connecting rod 141. Rotating the nut adjusts the length of the portion of the bolt between the second connecting part 114 and the fixing seat 13 along the vertical direction of the transition device 100. This allows adjustment of the distance between the second connecting part 114 and the fixing seat 13 in the vertical direction of the transition device 100, based on the length of the secondary refrigeration section 32 in the vertical direction, thereby adjusting the length of the elastic tube 12. When the length of the elastic tube 12 is just sufficient to accommodate the secondary refrigeration section 32, the bolt and nut are tightened to fix the relative position of the bolt and the fixing seat 13. In other words, the length of the elastic tube 12 is adjusted by the locking element 143 and the fastener 142 to accommodate secondary refrigeration sections 32 of different lengths.

[0047] This application does not impose any restrictions on the structure of the locking member 143 and the fastener 142, as long as they can adjust the distance between the second connecting part 114 and the fixed seat 13 in the vertical direction of the transition device 100.

[0048] In some embodiments, a locking element 143 may be provided at the connection between the fastener 142 and the upper surface of the fixing seat 13.

[0049] In some embodiments, a locking element 143 may be provided at the connection between the fastener 142 and the lower surface of the fixing seat 13.

[0050] In other embodiments, locking elements 143 may be provided at the connection between the fastener 142 and the upper and lower surfaces of the fixing base 13.

[0051] With the above settings, the number and installation position of the locking parts 143 can be set according to actual needs, so as to improve the stability of the adjustment rod assembly 14 when adjusting the distance between the second connecting part 114 and the fixed seat 13 in the vertical direction of the transition device 100.

[0052] This application does not limit the number or installation position of the locking element 143, as long as it can fix the fastener 142 and the fixing seat 13.

[0053] In one embodiment, the accommodating member 11 includes an accommodating portion 112 with an accommodating cavity 111, a first connecting portion 113 for connecting the refrigeration equipment and the refrigeration unit 300, and a second connecting portion 114 connected to the elastic tube 12. The first connecting portion 113 and the second connecting portion 114 are located on both sides of the accommodating portion 112. In the above arrangement, a plurality of adjusting rod groups 14 are arranged around the accommodating portion 112 so that the plurality of adjusting rod groups 14 can uniformly adjust the degree of extension and retraction of different positions of the elastic tube 12, thereby making the length of the elastic tube 12 consistent at all positions.

[0054] In some embodiments, the first connecting portion 113 is located above the receiving portion 112 in the vertical direction of the transition device 100. The second connecting portion 114 is located below the receiving portion 112 in the vertical direction of the transition device 100.

[0055] In one embodiment, the second connecting portion 114 is provided with a support protrusion 1141 for supporting the refrigerator 300, and the support protrusion 1141 is located within the accommodating cavity 111. With this arrangement, the support protrusion 1141 can apply a supporting force to the refrigerator 300 located within the accommodating cavity 111. Since the primary refrigeration unit 31 is located within the accommodating cavity 111, the support protrusion 1141 can support the primary refrigeration unit 31, thereby improving the stability of the primary refrigeration unit 31 within the accommodating cavity 111, and consequently improving the operational stability of the primary refrigeration unit 31.

[0056] Specifically, the support protrusion 1141 has a cooling surface 1141a for contacting the cooling section (i.e., the primary cooling section 31) of the refrigerator 300. By providing the cooling surface 1141a, the contact area between the refrigerator 300 and the support protrusion 1141 can be increased, thereby improving the cooling effect between the refrigerator 300 and the support protrusion 1141, and thus improving the cooling effect of the refrigerator 300 on the housing 11. Since the housing 11 is connected to the refrigeration equipment, it is beneficial to improve the cooling effect of the refrigerator 300 on the refrigeration equipment.

[0057] For example, in this application, a primary indium sheet for the refrigerator 300 can be provided on the portion of the cooling surface 1141a that contacts the refrigerator 300, that is, a primary indium sheet for the refrigerator 300 can be provided on the portion of the supporting protrusion 1141 that contacts the refrigerator 300. The primary indium sheet for the refrigerator 300 is a component with high thermal conductivity. By using the primary indium sheet for the refrigerator 300, the efficiency of the housing 112 in transferring heat from the refrigeration equipment to the refrigerator 300 can be improved, thereby improving the cooling efficiency of the refrigerator 300 for the refrigeration equipment.

[0058] In one embodiment, the transition device 100 further includes a connecting flange 15 sleeved on the receiving portion 112. The connecting flange 15 is connected to the side of the first connecting portion 113 near the second connecting portion 114. The connecting flange 15 is also used to connect a refrigeration device, so that the first connecting portion 113 and the refrigeration device are detachably connected via the connecting flange 15. In the above arrangement, the connecting flange 15 is connected to the lower side of the first connecting portion 113 in the vertical direction of the transition device 100. Furthermore, the connecting flange 15 allows the receiving member 11 to be connected to the refrigeration device, thereby facilitating the refrigeration unit 300 to refrigerate the refrigeration device.

[0059] In some embodiments, the connecting flange 15 is detachably connected to the first connecting part 113 by bolts, and the connecting flange 15 is detachably connected to the refrigeration equipment by bolts.

[0060] In one embodiment, a first heating element 16 for heating the second connecting portion 114 is installed inside the second connecting portion 114, and a second heating element 17 for heating the fixing base 13 is installed inside the fixing base 13, so that the first heating element 16 and the second heating element 17 can heat the refrigerator 300. Since the refrigerator 300 and the refrigeration equipment need to be reheated when disassembling and assembling them, the above arrangement allows the refrigerator 300 to be reheated using the first heating element 16 and the second heating element 17, facilitating subsequent disassembly and assembly of the transition device 100, the refrigerator 300, and the refrigeration equipment.

[0061] In one embodiment, multiple first heating elements 16 are provided, and the multiple first heating elements 16 are inserted into the second connecting portion 114 in a vertical direction. That is, the multiple first heating elements 16 are inserted into the second connecting portion 114 in the vertical direction of the transition device 100. With the above arrangement, the multiple first heating elements 16 can improve the heating efficiency of the refrigerator 300, thereby improving the rewarming efficiency of the refrigerator 300.

[0062] Meanwhile, multiple first heating elements 16 are evenly arranged around the receiving portion 112. As described above, different positions of the refrigerator 300 can be heated evenly, thereby making different positions of the refrigerator 300 heat up evenly, so as to avoid excessive local temperature difference during the reheating process of the refrigerator 300, thus avoiding damage to the refrigerator 300 and extending the service life of the refrigerator 300.

[0063] In this embodiment, multiple second heating elements 17 are provided, and the multiple second heating elements 17 are inserted into the fixing base 13 in a horizontal direction. That is, the multiple second heating elements 17 are inserted into the fixing base 13 along a plane perpendicular to the vertical direction of the transition device 100. With the above arrangement, the heating efficiency of the second heating elements 17 on the refrigerator 300 can be improved, thereby improving the rewarming efficiency of the refrigerator 300.

[0064] Furthermore, multiple second heating elements 17 are evenly arranged around the elastic tube 12. As described above, different positions of the refrigerator 300 can be heated evenly, thereby ensuring uniform temperature rise in different positions of the refrigerator 300. This avoids excessive local temperature differences during the reheating process of the refrigerator 300, thus preventing damage to the refrigerator 300 and extending its service life.

[0065] In one embodiment, a first temperature sensor 18 for detecting the temperature of the first heating element 16 is also installed in the second connecting part 114, and a second temperature sensor 19 for detecting the temperature of the second heating element 17 is also installed in the fixing base 13. In this configuration, the first temperature sensor 18 can obtain the temperature of the first heating element 16 heating the refrigerator 300 in real time, and the second temperature sensor 19 can obtain the temperature of the second heating element 17 heating the refrigerator 300 in real time. This improves the accuracy of the temperature during the rewarming process of the refrigerator 300 by the first heating element 16 and the second heating element 17, thus avoiding damage to the refrigerator 300 and extending its service life.

[0066] Specifically, the first temperature sensor 18 is inserted vertically into the second connecting part 114, and the second temperature sensor 19 is connected to the fixing base 13. In the above arrangement, the second connecting part 114 is connected to the primary cooling section 31, and the fixing base 13 is connected to the secondary cooling section 32.

[0067] In some embodiments, since the cooling temperature range of the primary cooling section 31 is large, it is necessary to select a temperature sensor type with a large detection range to facilitate the detection of temperature changes in the second connection section 114, thereby improving the comprehensiveness of the feedback from the first temperature sensor 18 on the changes in the cooling effect of the primary cooling section 31.

[0068] In some embodiments, since the power of the secondary cooling section 32 is relatively small, a small change in its power will cause a large change in the cooling effect. Therefore, the second temperature sensor 19 needs to be selected as a sensor type with high measurement accuracy. By accurately detecting the temperature change of the mounting base 13, the feedback accuracy of the cooling effect of the secondary cooling section 32 can be improved, which will help improve the adjustment accuracy of the output power of the secondary cooling section 32, and thus improve the working efficiency of the secondary cooling section 32.

[0069] In one embodiment, the transition device 100 further includes a plurality of parallel members 21. Each parallel member 21 includes a first parallel surface 211 and a second parallel surface 212 that are parallel to each other. Each parallel member 21 is located between the second connecting portion 114 and the fixing seat 13. Each first parallel surface 211 abuts against the side surface of the second connecting portion 114 near the fixing seat 13, that is, each first parallel surface 211 abuts against the lower surface of the second connecting portion 114. Each second parallel surface 212 abuts against the side surface of the fixing seat 13 near the second connecting portion 114, that is, each second parallel surface 212 abuts against the upper surface of the fixing seat 13. With the above arrangement, the lower surface of the second connecting part 114 can be parallel to the upper surface of the fixed base 13. When the refrigerator 300, the housing 11 and the elastic tube 12 are assembled, it is beneficial for the cold-conducting surface 1141a to fit with the refrigerator 300, and also for the cold-conducting contact surface 131 to fit with the refrigerator 300. This can increase the contact area between the cold-conducting surface 1141a and the cold-conducting contact surface 131 and the refrigerator 300, thereby improving the cooling effect of the refrigerator 300 on the housing 11 and the fixed base 13, and thus improving the cooling effect of the refrigerator 300 on the refrigeration equipment.

[0070] In some embodiments, a cutout portion may be provided on each parallel member 21, for example, a hole may be made in each parallel member 21, thereby reducing the weight of each parallel member 21.

[0071] It should be noted that when the first parallel surface 211 of each parallel component 21 is fully attached to the lower surface of the second connecting portion 114, and the second parallel surface 212 of each parallel component 21 is fully attached to the upper surface of the fixing seat 13, the lower surface of the second connecting portion 114 and the upper surface of the fixing seat 13 are parallel, so that the refrigerator 300 is fully attached to the cooling surface 1141a and the cooling contact surface 131. After completing the above steps, the parallelism of the connecting flange 15 can be checked by a level to verify whether the lower surface of the second connecting portion 114 and the upper surface of the fixing seat 13 are parallel.

[0072] In this application, because the shape of the accommodating member 11 and / or the fixing base 13 differs from the shape of the refrigeration equipment, the accommodating member 11 and / or the fixing base 13 cannot be directly connected to the refrigeration equipment. Therefore, a connection structure made of copper or aluminum can be provided between the refrigeration equipment and the accommodating member 11, and / or between the refrigeration equipment and the fixing base 13, to facilitate heat exchange between the refrigeration equipment and the refrigeration unit 300, thereby improving the refrigeration effect of the refrigeration unit 300 on the refrigeration equipment.

[0073] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
