[0050] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0051] The following is for reference. Figures 1-19 This application describes a refrigeration device according to an embodiment of the present application.

[0052] It should be noted that the refrigeration equipment in this embodiment can be understood as a broad refrigeration storage device, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. Refrigeration equipment has diverse structural forms and a wide range of applications.

[0053] The refrigeration equipment includes a cabinet and a door. The cabinet includes an outer shell, an inner liner 1, and an insulation layer located between the outer shell and the inner liner 1. The outer shell covers the inner liner 1 and provides protection. The insulation layer can be a foam layer, which provides insulation and cushioning. The space between the outer shell and the inner liner 1 forms a machine compartment, which is used to house machines such as compressors and circuit breakers.

[0054] like Figures 1-3 As shown, the refrigeration equipment in this embodiment includes: an inner liner 1, a refrigeration system 2, and a mounting bracket assembly.

[0055] The inner liner 1 forms a compartment; the inner liner 1 of the refrigeration equipment is usually made of cold-resistant materials such as metal or plastic. The shape and size of the inner liner 1 are designed according to the purpose and capacity of the refrigeration equipment to meet the needs of storing items.

[0056] The refrigeration system 2 typically includes multiple refrigeration components such as a compressor, condenser, throttling device, and evaporator 22. These multiple refrigeration components are connected by a heat exchange tube assembly 21, which is filled with refrigerant to circulate among the multiple refrigeration components and achieve a refrigeration effect.

[0057] In this embodiment, the heat exchange tube assembly 21 is arranged in a multi-layer structure along the thickness direction of the inner liner 1 in at least a portion of the area. This arrangement can fully utilize the space between the inner liner 1 and the outer shell, increase the heat exchange area, improve cooling efficiency, and reduce the overall size of the unit. Furthermore, the multi-layer structure design allows for adjustment of the number and layout of heat exchange tubes in each layer according to actual needs, achieving a more uniform cooling effect.

[0058] like Figure 1 As shown, the mounting bracket assembly is installed on the inner liner 1. The mounting bracket assembly can be connected to the inner liner 1 by snap-fit, welding or plug-in connection.

[0059] The mounting bracket group forms a plurality of mounting positions 322, which include multiple groups arranged at intervals along the thickness direction, and each group is used to fix a layer of heat exchange pipe groups 21.

[0060] The mounting bracket group is used to fix the heat exchange pipe group 21, improve the stability of the heat exchange pipe group 21 installed outside the inner container 1, and improve the stability of the refrigeration system 2 in operation.

[0061] As shown in Figure 1 , the mounting bracket group is installed outside the inner container 1, and a plurality of mounting positions 322 are formed on the mounting bracket group. These mounting positions 322 include multiple groups arranged at intervals along the thickness direction of the inner container 1, and each group is used to fix a layer of heat exchange pipe groups 21. The multiple mounting positions 322 are used to fix multiple layers of heat exchange pipe groups 21 arranged along the thickness direction.

[0062] Among them, the mounting bracket group can include multiple mounting brackets of different structures, and one or a combination of different mounting brackets can be used to fix the heat exchange pipe group 21 in different directions.

[0063] For example, multiple layers of heat exchange pipe groups 21 distributed along the thickness direction can be supported and fixed, or multiple pipe segments of the same layer of heat exchange pipe groups 21 distributed along the transverse direction can be supported and fixed, or multiple pipe segments of the same layer of heat exchange pipe groups 21 distributed along the vertical direction can be supported and fixed.

[0064] According to the refrigeration equipment provided in the present application, by arranging the mounting bracket group, multiple layers of heat exchange pipe groups 21 distributed along the thickness direction can be fixed, so as to reduce the shaking or deformation of the multiple layers of heat exchange pipe groups 21 distributed along the thickness direction during operation, thereby reducing the change of the spacing of the multiple layers of heat exchange pipe groups 21 along the thickness direction, improving the stability of the spacing between the heat exchange pipes of each layer, and achieving more uniform refrigeration effect. At the same time, since the mounting bracket group can be mass-produced, by arranging the mounting bracket group, the heat exchange pipe groups 21 of multiple refrigeration equipment of the same model can be located at a predetermined position, thereby improving the consistency of the performance of the prototype during mass production, improving the qualification rate of the cooling speed and depth of the prototype, and thereby improving the stability of the refrigeration system 2.

[0065] As shown in Figure 1 , in some embodiments, the heat exchange pipe group 21 includes a serpentine pipe segment 211 extending along a first direction in at least part of the area, wherein the first direction is perpendicular to the thickness direction, the first direction is the extension direction after multiple bending of the serpentine pipe segment 211, and multiple pipe segments of the serpentine pipe segment 211 are distributed along the first direction.

[0066] In the embodiment, the heat exchange pipe group 21 effectively increases the heat exchange area by arranging the serpentine pipe segments 211, thereby improving the refrigeration efficiency; the distribution of the serpentine pipe segments 211 can prolong the arrangement area of the heat exchange pipe group 21, thereby avoiding the local overheating or subcooling phenomenon; and the design of the serpentine pipe segments 211 can arrange more heat exchange pipes in the limited space, thereby improving the space utilization rate and refrigeration effect of the refrigeration equipment.

[0067] As shown in Figure 1 , the mounting bracket group extends along the first direction, and the mounting bracket group extends along the first direction in which the serpentine pipe segments 211 extend, so as to firmly support the entire serpentine pipe segments 211 and reduce the shaking and deformation of the multiple pipe segments in the serpentine pipe segments 211.

[0068] As shown in Figure 2 , the mounting bracket group includes at least one mounting bracket, and multiple mounting positions 322 in the same group on the same mounting bracket are distributed along the first direction and used to position multiple pipe segments of the serpentine pipe segments 211 distributed along the first direction.

[0069] In the present application, the multiple mounting positions 322 used to position multiple pipe segments of the serpentine pipe segments 211 distributed along the first direction are arranged on the same mounting bracket, compared with the structure in which multiple mounting members are used to fix multiple pipe segments of the serpentine pipe segments 211, the mounting steps of the mounting bracket can be simplified, the number of the mounting bracket can be reduced, and the support effect of the mounting bracket on the multiple pipe segments of the serpentine pipe segments 211 can be improved.

[0070] In some embodiments, as shown in Figures 3-9 , the mounting bracket includes a mounting seat 31, a connecting portion 33, and multiple clamping members 32.

[0071] As shown in Figure 4 , the mounting seat 31 extends along the first direction, and the connecting portion 33 and the multiple clamping members 32 are both mounted on the mounting seat 31, the mounting seat 31 plays a role of bearing and fixing the multiple clamping members 32, and the mounting seat 31 can be arranged along the extension direction of the serpentine pipe segments 211.

[0072] The shape of the mounting seat 31 can be a straight line shape, an arc shape, or other suitable shapes for the layout of the serpentine pipe segments 211 along the first direction.

[0073] As shown in Figure 3 , multiple groups of the clamping members 32 are arranged on at least one side of the mounting seat 31 along the thickness direction, and the clamping members 32 form the mounting positions 322.

[0074] As shown in Figure 3 and Figure 6 , the multiple groups of the clamping members 32 can be arranged on one side or both sides of the mounting seat 31 along the thickness direction.

[0075] For example,Figure 3 and Figure 8 As shown, when multiple sets of clamping members 32 are provided on one side of the mounting base 31 along the thickness direction, if one set of clamping members 32 is provided on one side of the mounting base 31 along the thickness direction, the mounting bracket can fix and support multiple pipe segments distributed along the first direction in the same layer of serpentine pipe segment 211, thereby limiting the spacing of different pipe segments in the same layer of serpentine pipe segment 211 along the first direction; if multiple sets of clamping members 32 distributed along the thickness direction are provided on one side of the mounting base 31 along the thickness direction, it can limit both the spacing of different layers of heat exchange tube groups 21 along the thickness direction and the spacing of different pipe segments in the same layer of serpentine pipe segment 211 along the first direction.

[0076] like Figure 6 and Figure 7 As shown, when multiple sets of clamping members 32 are arranged on both sides of the mounting base 31 along the thickness direction, the mounting bracket can at least fix and support the adjacent layers of serpentine tube segments 211 distributed along the thickness direction, which limits the spacing of different layers of heat exchange tube groups 21 along the thickness direction, and also limits the spacing of different tube segments within the same layer of serpentine tube segment 211 along the first direction.

[0077] The mounting base 31 is connected to the inner liner 1 via the connecting part 33. The connecting part 33 can be connected to the inner liner 1 by means of threaded connection, welding, or snap-fit, depending on the material of the inner liner 1 and the design requirements of the mounting bracket.

[0078] In some embodiments, such as Figure 7 As shown, the clamping member 32 includes two opposing jaws 321, which are arranged symmetrically or in a mirror manner to jointly clamp the heat exchange tube.

[0079] One end of the gripper 321 is connected to the mounting base 31. The connection method can be welding, bolting, riveting or other suitable connection methods to improve the firmness of the connection between the gripper 321 and the mounting base 31.

[0080] like Figure 9 As shown, the two jaws 321 of the clamping member 32 form flanges 323 that bend towards each other at the ends opposite to the mounting base 31. The design of the flanges 323 increases the contact area between the jaws 321 and the heat exchange tube, improving the stability and reliability of clamping. At the same time, the flanges 323 can also play a guiding and positioning role, making it easier for the heat exchange tube to be clamped in the correct position and reducing the risk of the heat exchange tube detaching from the mounting position 322.

[0081] Two opposing clamps 321 form a mounting position 322, which is used to accommodate and fix the heat exchange tube. By adjusting the spacing between the clamps 321 and the shape of the flange 323, heat exchange tubes of different diameters and shapes can be accommodated.

[0082] The clamping jaw 321 can have a certain elasticity so as to adapt to the shape and size of the heat exchange pipe when clamping the heat exchange pipe. Such an elastic design can reduce the stress concentration on the heat exchange pipe and avoid causing damage.

[0083] The shape and size of the flange 323 can be optimized according to the shape and size of the heat exchange pipe. For example, for a circular heat exchange pipe, the flange 323 can be designed to be arc-shaped or conical to better fit the surface of the heat exchange pipe. For heat exchange pipes of other shapes, the flange 323 can also be adjusted accordingly.

[0084] In some embodiments, as shown in Figure 9 , the flange 323 is inclined towards the mounting seat 31 to guide the heat exchange pipe, making it easier to be placed in the mounting position 322 and not easy to fall off from the mounting position 322, which helps to simplify the assembly of the heat exchange pipe and the mounting bracket and improve the stability of the heat exchange pipe.

[0085] In some embodiments, as shown in Figure 8 , the mounting bracket further includes a first reinforcing portion 34 connected between the side wall of the clamping jaw 321 and the mounting seat 31. The first reinforcing portion 34 is used to enhance the connection strength between the clamping jaw 321 and the mounting seat 31, reducing the risk of connection rupture or loosening of the clamping jaw 321 when clamping the heat exchange pipe due to excessive force.

[0086] The shape and size of the first reinforcing portion 34 can be adjusted according to the shape, size of the clamping jaw 321 and the mounting seat 31, and the required reinforcing effect.

[0087] For example, the first reinforcing portion 34 can be designed to be triangular, rectangular or other shapes with better stability.

[0088] As shown in Figure 7 , the mounting bracket further includes a second reinforcing portion 35 connected between the flange 323 and the mounting seat 31, and at least part of the second reinforcing portion 35 is spaced apart from the side wall of the clamping jaw 321.

[0089] The second reinforcing portion 35 is used to enhance the connection strength between the flange 323 and the mounting seat 31, while avoiding excessive constraint or interference to the side wall of the clamping jaw 321. By being spaced apart, the elasticity of the clamping jaw 321 can be improved so that the clamping jaw 321 can maintain sufficient flexibility and adaptability when clamping the heat exchange pipe.

[0090] The shape and size of the second reinforcing portion 35 can also be adjusted according to the shape, size of the flange 323 and the mounting seat 31, and the required reinforcing effect. For example, the second reinforcing portion 35 can be designed to be arc-shaped, trapezoidal or other shapes to adapt to the inclination and curvature of the flange 323.

[0091] In embodiments, by setting the first reinforcing portion 34 and the second reinforcing portion 35, the overall strength and stability of the mounting bracket can be improved, so that the mounting bracket can better withstand the weight of the heat exchange pipe and the vibration and impact generated during the circulation of the refrigerant; and the design of the reinforcing portion helps to disperse and balance the stress distribution on the mounting bracket, reduces damage caused by stress concentration, and prolongs the service life of the mounting bracket and the refrigeration equipment.

[0092] In some embodiments, the mounting bracket further comprises a second reinforcing portion 35 connected between the flange 323 and the mounting seat 31, and at least part of the second reinforcing portion 35 is spaced apart from the side wall of the clamping jaw 321.

[0093] The second reinforcing portion 35 is used to enhance the connection strength between the flange 323 and the mounting seat 31, while avoiding excessive constraint or interference to the side wall of the clamping jaw 321. By being spaced apart, the elasticity of the clamping jaw 321 can be improved, so that the clamping jaw 321 can maintain sufficient flexibility and adaptability when clamping the heat exchange pipe.

[0094] The shape and size of the second reinforcing portion 35 can also be adjusted according to the shape, size of the flange 323 and the mounting seat 31, and the required reinforcing effect. For example, the second reinforcing portion 35 can be designed in an arc shape, a trapezoidal shape or other shapes to adapt to the inclination and curvature of the flange 323.

[0095] In some embodiments, the mounting bracket further comprises a first reinforcing portion 34 connected between the side wall of the clamping jaw 321 and the mounting seat 31.

[0096] The shape and size of the first reinforcing portion 34 can be adjusted according to the shape, size of the clamping jaw 321 and the mounting seat 31, and the required reinforcing effect.

[0097] For example, the first reinforcing portion 34 can be designed in a triangular shape, a rectangular shape or other shapes with better stability.

[0098] The mounting bracket further comprises a second reinforcing portion 35 connected between the flange 323 and the mounting seat 31, and at least part of the second reinforcing portion 35 is spaced apart from the side wall of the clamping jaw 321.

[0099] In some embodiments, as shown in Figure 5 and Figure 7 The connecting portion 33 has a clamping groove 331 for clamping with the end of the inner container 1.

[0100] The side surface of the inner container 1 and the bottom surface of the inner container 1 have coinciding extensions, which can improve the stability of the connection between the side surface of the inner container 1 and the bottom surface of the inner container 1, thereby improving the overall sealing performance of the inner container 1.

[0101] The clamping groove 331 of the connecting part 33 is matched with the shape of the end part of the inner container 1, so that the connecting part 33 is clamped with the end part.

[0102] In the embodiment, the clamping mode of the clamping groove 331 and the end part of the inner container 1 greatly simplifies the assembly process, improves the production efficiency, and the installation of the mounting bracket and the inner container 1 does not need to use additional fasteners (such as screws, nuts, etc.), thereby reducing the assembly time and cost.

[0103] In some embodiments, as shown in Figure 7 The slot width of the clamping groove 331 is greater than the slot bottom width of the clamping groove 331, that is, the slot of the clamping groove 331 is formed with a guide surface, and the slot of the clamping groove 331 is formed with an outwardly bent guide surface, so as to facilitate the assembly of the clamping groove 331 and the end part of the inner container 1.

[0104] In some embodiments, as shown in Figure 3 and Figure 4 The mounting seat 31 is provided with a plurality of first weight reduction grooves 311, and the plurality of first weight reduction grooves 311 are arranged in the extension direction of the mounting seat 31; and / or, the mounting seat 31 is provided with a plurality of first through holes 312.

[0105] In the embodiment, the mounting seat 31 is provided with a plurality of first weight reduction grooves 311 and / or a plurality of first through holes 312, which can reduce the weight of the mounting seat 31 under the premise of meeting the structural strength and stability, optimize the utilization of materials, facilitate the flow of foaming material from the first through hole 312 during the process of filling the foaming material between the inner container 1 and the outer shell, improve the stability of the combination of the mounting seat 31 and the foaming material, and thus improve the stability of the position of the mounting bracket, thereby improving the support and fixing effect of the mounting bracket on the heat exchange pipe group 21 and improving the stability of the refrigeration equipment.

[0106] The shape of the first weight reduction groove 311 can be designed as a circle, an ellipse, a rectangle or other shapes according to actual needs.

[0107] The plurality of first weight reduction grooves 311 are arranged in the extension direction of the mounting seat 31 to achieve the weight reduction effect while maintaining the overall stability of the structure.

[0108] In the embodiment, the design of the first weight reduction groove 311 significantly reduces the weight of the mounting seat 31, which helps to reduce the overall weight and cost of the refrigeration equipment. By reasonably designing the shape and arrangement of the first weight reduction groove 311, the utilization of materials can be optimized while the structural strength is maintained, and the utilization rate of materials is improved. The first weight reduction groove 311 can also increase the stability of the combination of the mounting seat 31 and the foaming material, thereby improving the support and fixing effect of the mounting bracket on the heat exchange pipe group 21 and improving the stability of the refrigeration equipment.

[0109] The first through hole 312 can be circular, square or other shapes, depending on the design requirements and processing capacity.

[0110] The first through hole 312 facilitates the flow of the foaming material from the first through hole 312 during the process of filling the foaming material between the inner container 1 and the outer shell, improves the stability of the mounting seat 31 combined with the foaming material, thereby improving the stability of the position of the mounting bracket, thereby improving the supporting and fixing effect of the mounting bracket on the heat exchange pipe group 21, and improving the stability of the refrigeration equipment.

[0111] In some embodiments, the mounting seat 31 is provided with a plurality of first weight reduction grooves 311, and the plurality of first weight reduction grooves 311 are arranged at intervals along the extension direction of the mounting seat 31.

[0112] The shape of the first weight reduction groove 311 can be designed as circular, elliptical, rectangular or other shapes according to actual needs.

[0113] The plurality of first weight reduction grooves 311 are arranged at intervals along the extension direction of the mounting seat 31 to achieve the effect of weight reduction while maintaining the overall stability of the structure.

[0114] In the present embodiment, the design of the first weight reduction groove 311 significantly reduces the weight of the mounting seat 31, which helps to reduce the overall weight and cost of the refrigeration equipment. By reasonably designing the shape and arrangement of the first weight reduction groove 311, the utilization of materials can be optimized while maintaining the structural strength, thereby improving the material utilization rate. The first weight reduction groove 311 can also increase the stability of the mounting seat 31 combined with the foaming material, thereby improving the supporting and fixing effect of the mounting bracket on the heat exchange pipe group 21, and improving the stability of the refrigeration equipment.

[0115] In some embodiments, as shown in Figure 5 and Figure 6 The mounting seat 31 is provided with a plurality of first through holes 312.

[0116] The first through hole 312 can be circular, square or other shapes, depending on the design requirements and processing capacity.

[0117] The first through hole 312 facilitates the flow of the foaming material from the first through hole 312 in the case of filling the foaming material between the inner container 1 and the outer shell, improves the stability of the mounting seat 31 combined with the foaming material, thereby improving the stability of the position of the mounting bracket, thereby improving the supporting and fixing effect of the mounting bracket on the heat exchange pipe group 21, and improving the stability of the refrigeration equipment.

[0122] The first mounting bracket 36 is used to fix the heat exchange tube group 21 in the same layer, and the plurality of mounting positions 322 can be arranged on the same side of the mounting seat 31 of the first mounting bracket 36.

[0123] For example, when the first mounting bracket 36 is installed between the inner container 1 and the heat exchange tube group 21 close to the inner container 1, the first mounting bracket 36 can be used to position the heat exchange tube group 21 close to the inner container 1.

[0124] For example, when the first mounting bracket 36 is installed between the heat exchange tube group 21 close to the inner container 1 and the heat exchange tube group 21 far from the inner container 1, the first mounting bracket 36 can be used to position the heat exchange tube group 21 far from the inner container 1, or can be used to position the heat exchange tube group 21 close to the inner container 1, depending on the orientation of the first mounting bracket 36.

[0125] In some embodiments, as shown in Figure 1 , the refrigeration system 2 further includes an evaporator 22 wound around the inner container 1, and the side of the mounting seat 31 of the first mounting bracket 36 away from the corresponding clamping piece 32 abuts against the evaporator 22, so that when the first mounting bracket 36 is installed between the evaporator 22 and the heat exchange tube group 21 close to the inner container 1, the first mounting bracket 36 can define the spacing between the evaporator 22 and the heat exchange tube group 21 close to the inner container 1.

[0126] In this embodiment, the evaporator 22 wound around the inner container 1 can have a multi-point support effect on the support seat of the first mounting bracket 36, thereby improving the stability of the position of the first mounting bracket 36.

[0130] The mounting seat 31 of the second mounting bracket 37 is located between two adjacent heat exchange pipe groups 21, and can limit the spacing between the two adjacent heat exchange pipe groups 21.

[0131] In some embodiments, as shown in Figure 6 and Figure 7 The second mounting bracket 37 further includes at least one first support portion 373, and the first support portion 373 protrudes from the mounting seat 31 and is higher than the clamping piece 32.

[0132] In the case of the second mounting bracket 37 being installed in the normal direction, the first support portion 373 faces the inner container 1, and the first support portion 373 abuts against the inner container 1 to support the second mounting bracket 37 and improve the stability of the relative position between the second mounting bracket 37 and the inner container 1.

[0133] As shown in Figure 1 and Figure 3 In the case of the second mounting bracket 37 being installed in the reverse direction, the first support portion 373 faces the outer shell, and the first support portion 373 can abut against the outer shell to support the second mounting bracket 37 and improve the stability of the relative position between the second mounting bracket 37 and the inner container 1.

[0134] The first support portion 373 can include a plurality of first support portions 373, and the plurality of first support portions 373 are distributed along the extension direction of the second mounting bracket 37 to support the second mounting bracket 37 at multiple points.

[0135] In some embodiments, as shown in Figure 8 and Figure 9 The mounting bracket group includes at least one third mounting bracket 38, and the plurality of mounting positions 322 on the third mounting bracket 38 are in the same group along the thickness direction, and at least one mounting position 322 is used to position a plurality of heat exchange pipe groups 21.

[0136] The third mounting bracket 38 is used for fixing the same layer heat exchange pipe group 21, and at the same time is used for fixing the connecting pipe between different refrigeration components, and the connecting pipe can be located at different layers with the fixed heat exchange pipe group 21.

[0137] In actual use, the refrigeration system 2 includes a heat exchanger, a regenerator, an evaporator 22 and an evaporative condenser.

[0138] The evaporative condenser and the heat exchanger are distributed along the transverse direction, the heat exchanger and the regenerator are spaced apart and stacked along the thickness direction, and the evaporator 22 is wound on the outer wall of the inner container 1.

[0139] The heat exchanger includes a first serpentine pipe section and a first connecting section, the first serpentine pipe section extends along a first direction, and the first serpentine pipe section and the first connecting section are distributed along the transverse direction.

[0140] The regenerator includes a second serpentine pipe section and a second connecting section, the second serpentine pipe section extends along the first direction, and the second serpentine pipe section and the second connecting section are distributed along the transverse direction.

[0141] The evaporative condenser includes a third serpentine pipe section and a third connecting section, the third connecting section is located between the third serpentine pipe section and the first serpentine pipe section along the transverse direction, the third serpentine pipe section extends along the first direction, and the third serpentine pipe section and the third connecting section are distributed along the transverse direction.

[0142] Part of the evaporator 22, part of the regenerator and part of the heat exchanger are distributed along a direction from the inner container 1 to the outer shell, and part of the evaporator 22 and part of the evaporative condenser are distributed along a direction from the inner container 1 to the outer shell.

[0143] The first mounting bracket 36 is arranged between the evaporator 22 and the regenerator, and is used for fixing the spacing between the regenerator and the evaporator 22, and at the same time is used for positioning the stability of each section of the second serpentine pipe section of the regenerator.

[0144] The second mounting bracket 37 is arranged between the evaporator 22 and the outer shell, and is used for fixing the spacing between the regenerator and the evaporator 22, the spacing between the regenerator and the heat exchanger at the same time, and at the same time can position the stability of each section of the second serpentine pipe section of the regenerator and the stability of each section of the first serpentine pipe section of the heat exchanger.

[0145] The third mounting bracket 38 is arranged between the evaporator 22 and the evaporative condenser, and is used for fixing the spacing between the evaporative condenser and the evaporator 22, and at the same time is used for positioning the stability of each section of the third serpentine pipe section of the evaporative condenser, and at the same time can fix the connecting pipe of the evaporative condenser and the heat exchanger, and the connecting pipe is located on the side of the evaporative condenser away from the evaporator 22 along the thickness direction.

[0146] In some embodiments, as Figure 1 and Figure 3As shown, the heat exchange pipe group 21 is arranged as a plurality of pipe sections 212 arranged in transverse intervals in at least a partial region; the refrigeration device further comprises a fixing support 4, which forms a plurality of fixing positions 422, each of which is arranged in transverse intervals and used for fixing a pipe section 212.

[0147] For example, the plurality of pipe sections 212 arranged in transverse intervals of the heat exchange pipe group 21 can be a plurality of pipe sections 212 arranged in transverse intervals of the same refrigeration component, such as the heat exchange portion and the connecting portion 33 of the heat exchanger, the heat exchange portion and the connecting portion 33 of the regenerator, or the heat exchange portion and the connecting portion 33 of the evaporative condenser; or, the plurality of pipe sections 212 arranged in transverse intervals of the heat exchange pipe group 21 can be a plurality of pipe sections 212 arranged in transverse intervals of different refrigeration components, such as the heat exchange portion of the heat exchanger and the connecting portion 33 of the evaporative condenser.

[0148] The plurality of pipe sections 212 can be straight pipes or curved pipes, and the fixing support 4 is used for fixing the intervals between adjacent pipe sections 212 or non-adjacent pipe sections of the plurality of pipe sections 212 arranged in transverse intervals, so as to support the weight of the entire heat exchange pipe group 21 and resist the vibration and stress generated by the refrigeration system 2 during operation, thereby improving the stability and positional accuracy of the heat exchange pipe group 21 in the inner container 1 of the refrigeration device, and improving the stability of the refrigeration system 2.

[0149] The number of fixing supports 4 can be distributed according to the length and number of the heat exchange pipe group 21, for example, a plurality of fixing supports 4 can be distributed to form multi-point positioning and support, thereby improving the transverse positioning and support effect of the heat exchange pipe group 21.

[0150] In the embodiment, as shown in Figure 1 , Figure 3 and Figure 11 , the mounting support group and the fixing support 4 cooperate, the mounting support group can position and support the plurality of layers of heat exchange pipes of the heat exchange pipe group 21 arranged in the thickness direction and position the serpentine pipe sections 211 extending in the vertical direction of the same layer of heat exchange pipes, and the fixing support 4 can position and support the plurality of pipe sections 212 arranged in transverse intervals of the same layer of heat exchange pipes of the heat exchange pipe group 21, so as to position and support the pipe sections arranged in transverse, vertical and thickness directions of the heat exchange pipe group 21, support the weight of the entire heat exchange pipe group 21 and resist the vibration and stress generated by the refrigeration system 2 during operation, thereby improving the stability of the intervals between adjacent pipe sections arranged in transverse, vertical and thickness directions of the heat exchange pipe group 21, improving the uniformity of the heat exchange temperature of the heat exchange pipe group 21, improving the qualification rate of the prototype cooling speed and depth, and improving the stability of the refrigeration system 2.

[0151] The size and shape of the fixing position 422 match the heat exchange pipe group 21 to improve the fixing and supporting effect on the pipe portion 212. In this way, each pipe portion 212 can be independently and stably supported, thereby avoiding displacement or deformation caused by vibration or temperature change, improving the stability of the spacing between adjacent pipe portions 212, and improving the spacing between the multiple pipe portions 212 distributed in the transverse direction of the heat exchange pipe group 21 to make the multiple pipe portions 212 distributed in the transverse direction meet the preset heat exchange design.

[0152] In addition, the number and position of the fixing position 422 can also be adjusted according to the specific heat exchange pipe group 21 design and refrigeration requirements to achieve the best fixing effect and heat exchange performance.

[0153] As shown in FIG. 4, the fixing support 4 can be mounted on the inner container 1, and the fixing support 4 can also be mounted on the heat exchange pipe group 21. The fixing support 4 is mounted and the heat exchange pipe group 21 is positioned by being assembled with the heat exchange pipe group 21. Figure 11

[0154] In some embodiments, the heat exchange pipe group 21 includes the serpentine pipe portion 211 and the connecting portion 213 distributed in the transverse direction in at least part of the area.

[0155] The adjacent serpentine pipe portion 211 and connecting portion 213 distributed in the transverse direction can belong to the same refrigeration component or different refrigeration components, and can be the same layer or different layers in the thickness direction.

[0156] At least part of the serpentine pipe portion 211 and at least part of the connecting portion 213 can extend in the first direction and be distributed in the transverse direction. The multiple mounting positions 322 on the fixing support 4 are distributed in the transverse direction to position and support the position and spacing of the adjacent serpentine pipe portion 211 and connecting portion 213.

[0157] In this embodiment, the heat exchange pipe group 21 is provided with the serpentine pipe portion 211, which effectively increases the heat exchange area and improves the refrigeration efficiency. The distribution of the serpentine pipe portion 211 can extend the arrangement area of the heat exchange pipe group 21 to avoid local overheating or overcooling. The design of the serpentine pipe portion 211 can arrange more heat exchange pipes in a limited space to improve the space utilization and refrigeration effect of the refrigeration equipment.

[0158] The connecting portion 213 can be used to connect the serpentine pipe portion 211 and other pipe portions.

[0159] ​Exemplarily, one end of the connecting section 213 of the heat exchanger away from the serpentine tube section 211 can be used to connect the first condenser and the first compressor; one end of the connecting section 213 of the heat exchanger away from the serpentine tube section 211 can be used to connect the second condenser and the second compressor, and one end of the connecting section 213 of the evaporative condenser away from the serpentine tube section 211 can be used to connect the heat exchanger and the serpentine tube section 211 of the heat exchanger.

[0160] As shown in Figure 11 , Figure 12 and Figure 13 , the fixing support 4 extends in the transverse direction, multiple mounting positions 322 on the same fixing support 4 are distributed in the transverse direction, and are used to position the adjacent serpentine tube sections 211 and connecting sections 213.

[0161] The adjacent serpentine tube sections 211 and connecting sections 213 can be in the same layer along the thickness direction of the heat exchange tube group 21, or can be in different layers along the thickness direction.

[0162] In some embodiments, as shown in Figure 11 , Figure 12 and Figure 13 , the fixing support 4 comprises a fixing seat 41 and multiple fixing members 42.

[0163] The fixing seat 41 extends in the transverse direction, and the fixing seat 41 bears and fixes the multiple fixing members 42.

[0164] The multiple fixing members 42 are arranged on at least one side of the fixing seat 41 along the thickness direction, and the multiple fixing members 42 can be arranged on one side or both sides of the fixing seat 41 along the thickness direction to fix one or more layers of the heat exchange tube group 21 along the thickness direction.

[0165] The fixing member 42 forms a fixing position 422.

[0166] Exemplarily, as shown in Figure 15 and Figure 16 , in the case where the multiple fixing members 42 are arranged on one side of the fixing seat 41 along the thickness direction, if one group of fixing members 42 is arranged on one side of the fixing seat 41 along the thickness direction, the fixing support 4 can fix and support the serpentine tube sections 211 and connecting sections 213 distributed in the same layer, so as to limit the spacing of the serpentine tube sections 211 and connecting sections 213 distributed in the same layer along the transverse direction; if multiple groups of fixing members 42 distributed along the thickness direction are arranged on one side of the fixing seat 41 along the thickness direction, both the spacing of the serpentine tube sections 211 and connecting sections 213 distributed in different layers along the thickness direction and the spacing of the serpentine tube sections 211 and connecting sections 213 distributed in the same layer along the transverse direction can be limited.

[0167] As shown in Figure 11 , Figure 12 and Figure 13As shown, in the case where multiple sets of fixing members 42 are arranged on both sides of the fixing seat 41 along the thickness direction, the fixing support 4 can at least fix and support the adjacent layer of serpentine tube segments 211 and connecting segments 213 along the thickness direction in the transverse direction, not only limiting the spacing of the heat exchange tube groups 21 along the thickness direction, but also limiting the spacing of the serpentine tube segments 211 and connecting tubes along the transverse direction.

[0168] In some embodiments, as shown in Figure 11 and Figure 16 , the fixing member 42 includes two oppositely arranged fixing claws, one end of the fixing claw is connected to the fixing seat 41, and the end of the two fixing claws of the fixing member 42 away from the fixing seat 41 forms a bending portion 421 bent towards each other, and the two oppositely arranged fixing claws form a fixing position 422.

[0169] The design of the bending portion 421 increases the contact area between the fixing claw and the heat exchange tube, improves the stability and reliability of clamping. At the same time, the bending portion 421 can also play a guiding and positioning role, so that the heat exchange tube is more easily clamped in the correct position, reducing the risk of the heat exchange tube from the fixing position 422.

[0170] The two oppositely arranged fixing claws form a fixing position 422 for accommodating and fixing the heat exchange tube. By adjusting the spacing between the fixing claws and the shape of the bending portion 421, different diameters and shapes of heat exchange tubes can be adapted.

[0171] Among them, the fixing claw can have a certain elasticity, so as to adapt to the change of the shape and size of the heat exchange tube when clamping. This elastic design can reduce the pressure concentration on the heat exchange tube and avoid damage.

[0172] The shape and size of the bending portion 421 can be optimized according to the shape and size of the heat exchange tube. For example, for circular heat exchange tubes, the bending portion 421 can be designed as an arc or a cone to better fit the surface of the heat exchange tube. For other shapes of heat exchange tubes, the bending portion 421 can also be adjusted accordingly.

[0173] In some embodiments, the bending portion 421 is inclined towards the fixing seat 41 to guide the heat exchange tube, so that the heat exchange tube is more easily put into the fixing position 422 and is not easy to fall off from the fixing position 422, which helps to simplify the assembly of the heat exchange tube and the fixing support 4 and improve the stability of the heat exchange tube.

[0174] In some embodiments, as shown in Figure 11 , Figure 12 and Figure 13 , the fixing support 4 further includes a reinforcing member 43 connected between the bending portion 421 and the fixing seat 41, and at least part of the reinforcing member 43 is arranged spaced apart from the side wall of the fixing claw.

[0175] The reinforcing member 43 is used to enhance the connection strength between the bending portion 421 and the fixing seat 41, while avoiding excessive constraints or interference to the side wall of the fixing claw. By being arranged at intervals, the elasticity of the fixing claw can be improved, so that the fixing claw can maintain sufficient flexibility and adaptability when clamping the heat exchange pipe.

[0176] The shape and size of the reinforcing member 43 can also be adjusted according to the shape, size of the bending portion 421 and the fixing seat 41, and the required reinforcing effect. For example, the reinforcing member 43 can be designed in an arc shape, a trapezoidal shape or other shapes to adapt to the inclination and bending of the bending portion 421.

[0177] In embodiments, by arranging the reinforcing member 43, the overall strength and stability of the fixing support 4 can be improved, so that the fixing support 4 can better withstand the weight of the heat exchange pipe and the vibration and impact generated during the circulation of the refrigerant; and the design of the reinforcing portion helps to disperse and balance the stress distribution on the fixing support 4, reduces damage caused by stress concentration, and prolongs the service life of the fixing support 4 and the refrigeration equipment.

[0178] In some embodiments, as shown in Figs. Figure 11 , Figure 12 and Figure 13 , the fixing seat 41 is provided with a plurality of second weight reduction grooves 44, the plurality of second weight reduction grooves 44 are arranged at intervals along the extension direction of the fixing seat 41, and the fixing seat 41 is provided with a plurality of second through holes 46.

[0179] In this embodiment, the fixing seat 41 is provided with a plurality of second weight reduction grooves 44 and / or a plurality of second through holes 46, which can reduce the weight of the fixing seat 41 under the premise of meeting the structural strength and stability, optimize the use of materials, facilitate the flow of foaming material from the second through holes 46 during the process of filling foaming material between the inner container 1 and the outer shell, improve the stability of the combination of the fixing seat 41 and the foaming material, thereby improving the positional stability of the fixing support 4, thereby improving the support and fixing effect of the fixing support 4 on the heat exchange pipe group 21, and improving the stability of the refrigeration equipment.

[0180] The shape of the second weight reduction groove 44 can be designed as a circle, an ellipse, a rectangle or other shapes according to actual needs.

[0181] The plurality of second weight reduction grooves 44 are arranged at intervals along the extension direction of the fixing seat 41 to achieve the weight reduction effect while maintaining the overall stability of the structure.

[0182] In this embodiment, the design of the second weight-reducing groove 44 significantly reduces the weight of the mounting base 41, helping to reduce the overall weight and cost of the refrigeration equipment. By rationally designing the shape and arrangement of the second weight-reducing groove 44, material utilization can be optimized and improved while maintaining structural strength. The second weight-reducing groove 44 can also increase the stability of the connection between the mounting base 41 and the foaming material, thereby improving the support and fixation effect of the mounting bracket 4 on the heat exchange tube assembly 21 and enhancing the stability of the refrigeration equipment.

[0183] The second through hole 46 can be circular, square, or other shapes, depending on the design requirements and processing capabilities.

[0184] During the process of filling the foam material between the inner liner 1 and the outer shell, it is convenient for the foam material to flow through the second through hole 46, which improves the stability of the combination between the fixing seat 41 and the foam material, thereby improving the positional stability of the fixing bracket 4, thus improving the support and fixing effect of the fixing bracket 4 on the heat exchange tube assembly 21, and improving the stability of the refrigeration equipment.

[0185] In some embodiments, such as Figure 13 As shown, the mounting base 41 is provided with multiple second through holes 46.

[0186] The second through hole 46 can be circular, square, or other shapes, depending on the design requirements and processing capabilities.

[0187] During the process of filling the foam material between the inner liner 1 and the outer shell, it is convenient for the foam material to flow through the second through hole 46, which improves the stability of the combination between the fixing seat 41 and the foam material, thereby improving the positional stability of the fixing bracket 4, thus improving the support and fixing effect of the fixing bracket 4 on the heat exchange tube assembly 21, and improving the stability of the refrigeration equipment.

[0188] In some embodiments, the mounting base 41 is provided with a plurality of second weight-reducing grooves 44, which are spaced apart along the extending direction of the mounting base 41.

[0189] The shape of the second weight-reducing groove 44 can be designed as a circle, ellipse, rectangle or other shapes according to actual needs.

[0190] Multiple second weight-reducing grooves 44 are arranged at intervals along the extension direction of the fixed base 41 to achieve weight reduction while maintaining the overall stability of the structure.

[0191] In this embodiment, the design of the second weight-reducing groove 44 significantly reduces the weight of the mounting base 41, helping to reduce the overall weight and cost of the refrigeration equipment. By rationally designing the shape and arrangement of the second weight-reducing groove 44, material utilization can be optimized and improved while maintaining structural strength. The second weight-reducing groove 44 can also increase the stability of the connection between the mounting base 41 and the foaming material, thereby improving the support and fixation effect of the mounting bracket 4 on the heat exchange tube assembly 21 and enhancing the stability of the refrigeration equipment.

[0192] In some embodiments, such as Figure 11 As shown, the heat exchange tube assembly 21 includes, in at least a portion of the region, a serpentine tube segment 211 and a connecting segment 213 distributed laterally. The projection of the serpentine tube segment 211 along the thickness direction falls within the projection of the inner liner 1 along the thickness direction, while the projection of the connecting segment 213 along the thickness direction is located outside the projection of the inner liner 1 along the thickness direction.

[0193] When viewed from the thickness direction (i.e., the direction perpendicular to the main plane of the inner liner 1), the projection of the serpentine tube segment 211 falls entirely within the projection of the inner liner 1. This means the serpentine tube segment 211 is tightly arranged on one side of the inner liner 1, fully utilizing the space between the inner liner 1 and the outer shell for heat exchange. The projection of the connecting segment 213 along the thickness direction lies outside the projection of the inner liner 1 along the thickness direction. The connecting segment 213 needs to bypass the inner liner 1 to connect with other refrigeration components and thus extends to the other side of the inner liner 1.

[0194] Among them, the projection of a portion of the multiple fixing positions 422 distributed laterally along the thickness direction falls within the projection of the inner liner 1 along the thickness direction, so as to fix the serpentine pipe section 211; the projection of a portion of the multiple fixing positions 422 distributed laterally along the thickness direction falls outside the projection of the inner liner 1 along the thickness direction, so as to fix the connecting section 213.

[0195] The fixing bracket 4 includes at least two of the following structures:

[0196] Firstly, such as Figure 14 , Figure 15 and Figure 16 As shown, the fixed bracket 4 includes multiple fixed positions 422 distributed laterally. The fixed bracket 4 is used to position the pipe sections of the heat exchange tube group 21 distributed laterally in the same layer.

[0197] In this embodiment, the heat exchange tube assembly 21 includes, in at least a portion of the region, two transversely distributed serpentine tube segments 211 and a connecting segment 213 between the two serpentine tube segments 211.

[0198] The two serpentine tube segments 211 may belong to different refrigeration components or the same refrigeration component, and the connecting segment 213 is used to connect the two serpentine tube segments 211.

[0199] likeFigure 14 As shown, the fixing support 4 includes a plurality of fixing supports 4, at least one of the plurality of fixing supports 4 is used to position one of the two serpentine tube segments 211 and the connecting segment 213, and at least another one of the plurality of fixing supports 4 is used to position the other of the two serpentine tube segments 211 and the connecting segment 213.

[0200] In the present embodiment, the plurality of fixing positions 422 distributed along the transverse direction on the fixing support 4 are used to fix the serpentine tube segments 211 and the connecting segments 213 distributed along the transverse direction, and the plurality of fixing supports 4 are used to fix the plurality of serpentine tube segments 211 and the plurality of connecting segments 213. By providing the plurality of fixing supports 4, the heat exchange tube group 21 can be supported at multiple points along the transverse direction, thereby improving the stability of the spacing between the multiple tube segments of the heat exchange tube group 21 along the transverse direction, and thereby improving the consistency of the cooling speed of the heat exchange tube group 21 along the transverse direction.

[0201] Secondly, as shown in Figure 11 , Figure 12 and Figure 13 , the plurality of fixing positions 422 includes a plurality of groups distributed along the thickness direction, the plurality of groups of fixing positions 422 are distributed along the thickness direction of the fixing support 4, and each group of fixing positions 422 includes a plurality of fixing positions 422 distributed along the transverse direction.

[0202] The fixing support 4 is used to fix and position the heat exchange tube group 21 distributed along the thickness direction and the transverse direction of the heat exchange tube group 21.

[0203] In the present embodiment, the heat exchange tube group 21 is arranged as multiple layers along the thickness direction in at least part of the region; the plurality of fixing positions 422 on the fixing support 4 form multiple groups arranged at intervals along the thickness direction, the plurality of fixing positions 422 of different groups on the same fixing support 4 are distributed along the thickness direction, and are used to position the multiple layers of the heat exchange tube group 21.

[0204] Among them, the plurality of fixing positions 422 of different groups on the fixing support 4 are arranged in position to facilitate the fixing of the heat exchange tube group 21 arranged in position along the thickness direction, and to reduce the difficulty of assembly.

[0205] For example, the fixing positions 422 arranged in position can be used to fix two adjacent serpentine tube segments 211 arranged in position, or two adjacent connecting segments 213 arranged in position, or two adjacent serpentine tube segments 211 and connecting segments 213 arranged in position.

[0206] In some embodiments, as shown in Figure 11 , Figure 12 and Figure 13 , the fixing support 4 further includes a clamping portion 45, the clamping portion 45 is protrudingly arranged along the thickness direction of the fixing seat 41, and in the case that the clamping portion 45 is located on the side facing the inner container 1, the clamping portion 45 abuts against the inner container 1 to provide additional support and stability for the fixing support 4.

[0207] Exemplarily, the clamping portion 45 can abut against one side of the inner container 1 along the transverse direction to limit the fixed support 4 in the transverse direction, thereby limiting the heat exchange pipe group 21 in the transverse direction and improving the stability of the heat exchange pipe group 21 in the transverse direction; the clamping portion 45 can abut against one side of the inner container 1 along the vertical direction to limit the fixed support 4 in the vertical direction, thereby limiting the heat exchange pipe group 21 in the vertical direction and improving the stability of the heat exchange pipe group 21 in the vertical direction.

[0208] In the embodiment, the inner container 1 abuts against the clamping portion 45, which can reduce the damage of the heat exchange pipe group 21 due to movement or vibration during installation and use.

[0211] In some embodiments, as shown in Figure 17 The refrigeration device further includes a bearing support 5, the bearing support 5 is supported on the evaporator 22, and the bearing support 5 is provided with an annular bearing position 512, and the capillary tube 214 is wound on the annular bearing position 512.

[0212] According to the refrigeration device provided in the embodiments of the present application, the bearing support 5 is arranged to position the capillary tube 214, so as to limit the distance between the capillary tube 214 and the evaporator 22, the distance between the capillary tube 214 and the inner container 1, and the distance between the capillary tube 214 and the outer shell, thereby reducing the influence of the temperatures of the inner container 1, the evaporator 22 and the outer shell on the temperature of the capillary tube 214. Since the bearing support 5 can be mass-produced, by arranging the bearing support 5, the capillary tube 214 can be located at a predetermined position in a plurality of refrigeration devices of the same model which are mass-produced, thereby improving the consistency of performance when the prototype is mass-produced.

[0213] In the present embodiment, as shown in Figure 1 , Figure 2 and Figure 17 , the carrier bracket 5, the mounting bracket set and the fixing bracket 4 cooperate to position each pipe segment in the heat exchange pipe set 21, so that the multiple layers of heat exchange pipes in the heat exchange pipe set 21, the serpentine pipe segments 211 and the connecting segments 213 distributed in the same layer in the transverse direction, the serpentine pipe segments 211 extending in the first direction in the same layer, and the capillary tubes 214 in the same layer are all positioned. This can make the heat exchange pipe set 21 in multiple mass-produced refrigeration devices of the same model all be located at a predetermined position, thereby improving the consistency of the performance of the prototype in mass production, improving the reliability of the refrigeration system 2 in each refrigeration device, and prolonging the service life of the refrigeration device.

[0214] Among them, one side of the carrier bracket 5 is supported on the evaporator 22, and the other side can be supported on the shell or spaced from the shell. The carrier bracket 5 is assembled with the capillary tube 214 before being filled with foaming material.

[0215] The evaporator 22 is wound on the inner container 1, and the evaporator 22 is used to absorb heat to achieve the refrigeration effect of the chamber formed by the inner container 1.

[0216] As shown in Figure 18 and Figure 19 , the annular carrier position 512 on the carrier bracket 5 is used to orderly wind the capillary tube 214, thereby forming a compact and efficient capillary tube 214 heat exchange pipe set 21, and improving the throttling effect.

[0217] The annular design of the annular carrier position 512 can reduce the installation difficulty of the capillary tube 214, extend the length of the capillary tube 214 in a limited space, and improve the refrigeration efficiency.

[0218] In some embodiments, as shown in Figure 2 and Figure 3 , the carrier bracket 5 includes a winding base 51, and the outer peripheral wall of the winding base 51 forms the annular carrier position 512.

[0219] The winding base 51 is the core part of the carrier bracket 5, and its shape and structure are crucial to the performance and stability of the entire refrigeration device. In the present embodiment, the winding base 51 is designed to have an outer peripheral wall that forms the annular carrier position 512.

[0220] In some embodiments, as shown in Figure 18 and Figure 19 , the outer peripheral wall of the winding base 51 is provided with a stop edge 511 at both ends in the axial direction, the stop edge 511 extends around the circumference of the winding base 51, and the stop plate and the outer peripheral wall of the winding base 51 form the annular carrier position 512.

[0221] The main design purpose of the retaining edge 511 is to reduce the slippage or loosening of the capillary tube 214 from the annular bearing position 512 during winding and working, and to increase the winding layers of the capillary tube 214 in the annular bearing position 512 in the axial direction.

[0222] The retaining edge 511 extends along the outer peripheral wall of the winding base 51. The retaining edge 511 can extend along the circumference of the winding base 51 to form a complete annular structure, or the retaining edge 511 can extend along the circumference of the winding base 51 to form a plurality of arc-shaped structures.

[0223] In this embodiment, the retaining edge 511 not only provides a physical blocking effect for the capillary tube 214, but also increases the friction between the capillary tube 214 and the winding base 51 through its close-fitting design, so that the capillary tube 214 is more stable after winding. After foaming, the retaining edge 511 can make the winding base 51 and the foamed thermal insulation layer form an interlocking structure, improve the bonding strength, and thus improve the stability of the position of the winding base 51.

[0224] In some embodiments, as shown in Figure 18 and Figure 19 The retaining edge 511 includes a plurality of retaining edges 511 located at the same end and spaced apart around the circumference of the winding base 51. The retaining edge 511 also extends along the circumference of the winding base 51 to form a plurality of arc-shaped structures.

[0225] In this embodiment, the retaining edge 511 structure with multiple segments can reduce material costs, and at the same time form an interlocking structure with the thermal insulation layer to improve the bonding strength, thereby improving the stability of the position of the winding base 51.

[0226] In some embodiments, the retaining edges 511 located at different ends are arranged in a staggered manner, which can further form an interlocking structure with the thermal insulation layer to improve the bonding strength, thereby improving the stability of the position of the bearing bracket 5.

[0227] In some embodiments, as shown in Figure 18 and Figure 19 The retaining edge 511 located at one end of the winding base 51 away from the inner container 1 is provided with a through hole 5111. The through hole 5111 can be used for assembly with the shell, or can form an interlocking structure with the thermal insulation layer to improve the bonding strength.

[0228] In some embodiments, the inner wall of the winding base 51 is provided with a reinforcing rib 513 protruding inward. The retaining edge 511 and the reinforcing rib 513 are arranged on the inner and outer sides of the winding base 51. The reinforcing rib 513 can improve the structural strength of the winding base 51, and can form an interlocking structure with the thermal insulation layer to improve the bonding strength.

[0229] The reinforcing rib 513 can extend around the circumference of the winding base 51 to form an annular reinforcing structure, or can include a plurality of reinforcing ribs 513 distributed at intervals around the circumference of the winding base 51.

[0230] In some embodiments, as shown in Figure 18 and Figure 19 The inner wall of the winding base 51 is provided with at least one reinforcing rib 513 protruding inward, and the at least one reinforcing rib 513 is distributed around the circumference of the winding base 51. The design of the reinforcing rib 513 can form an interlocking structure with the insulation layer to improve the bonding strength.

[0231] In some embodiments, the side of the spoke 52 away from the inner container 1 is not higher than the side of the winding base 51 away from the inner container 1, so as to reduce the difficulty of installing the load-bearing support 5 between the inner container 1 and the outer shell.

[0232] In some embodiments, as shown in Figure 2 and Figure 3 The load-bearing support 5 further includes spokes 52, and the ends of the spokes 52 are connected to the winding base 51, respectively.

[0233] The spokes 52 are used to provide additional support and stability to the winding base 51. Through the design of the spokes 52 connected to the winding base 51, the spokes 52 can effectively disperse and bear the weight and stress from the winding base 51 and the capillary tubes 214 thereon, thereby improving the load-bearing capacity and stability of the entire load-bearing support 5. At the same time, the structural strength of the load-bearing support 5 can also be improved, and the deformation of the load-bearing support 5 during foaming can be reduced.

[0234] The spokes 52 and the winding base 51 can be connected by welding, bolting, or one-piece forming, etc., to improve the stability of the connection between the spokes 52 and the winding base 51, thereby reducing the possibility of the capillary tubes 214 loosening or falling off due to deformation of the load-bearing support 5 during use.

[0235] The winding base 51 forms a hub, and the spokes 52 include a plurality of spokes radiating from the hub to the rim. The number, shape, and layout of the spokes can be adjusted according to application requirements.

[0236] Since the plurality of spokes radiate from the hub center to the rim, at least part of the spacing between adjacent spokes can form an interlocking structure with the insulation layer to improve the bonding strength, and the risk of deformation of the load-bearing support 5 during foaming can be reduced.

[0237] In some embodiments, as shown in Figure 18 and Figure 19 The spoke 52 is provided with a third weight-reducing groove 521 arranged along the extension direction of the spoke 52.

[0238] The third weight-reducing groove 521 can be circular, oval, rectangular or other shapes according to actual needs.

[0239] The third weight-reducing groove 521 is arranged along the extension direction of the spoke 52, so as to reduce the weight while maintaining the overall stability of the structure.

[0240] In this embodiment, the third weight-reducing groove 521 significantly reduces the weight of the spoke 52, which helps to reduce the overall weight and cost of the refrigeration equipment. By reasonably designing the shape and arrangement of the third weight-reducing groove 521, the utilization of materials can be optimized while maintaining the structural strength, thereby improving the utilization rate of materials. The third weight-reducing groove 521 can also increase the stability of the spoke 52 combined with the foaming material, thereby improving the support and fixing effect of the load-bearing base on the capillary tube 214 and improving the stability of the refrigeration equipment.

[0241] In some embodiments, the spoke 52 protrudes from the load-bearing bracket 5 in the axial direction towards one side of the inner container 1, and the side of the spoke 52 towards the inner container 1 abuts against the evaporator 22.

[0242] The side of the spoke 52 towards the inner container 1 can be provided with a flexible layer, which can be plastic, rubber, etc., to protect the evaporator 22.

[0243] In this embodiment, by providing the spoke 52 protruding from the load-bearing bracket 5, a limiting effect between the load-bearing bracket 5 and the evaporator 22 can be achieved, the distance between the load-bearing bracket 5 and the evaporator 22 is increased, and the influence of the evaporator 22 or the inner container 1 on the temperature of the capillary tube 214 is reduced.

[0244] As shown in Figure 1 , Figure 2 and Figure 3 , the present application also provides a refrigeration equipment, which comprises an inner container 1, a refrigeration system 2 and a fixing bracket 4.

Meanwhile, since the fixed support 4 can be mass-produced, the heat exchange pipe group 21 can be located at the predetermined position in the multiple refrigeration equipment of the same model which is mass-produced by arranging the fixed support 4, and thus the consistency of the performance when the sample machine is mass-produced can be improved, the qualified rate of the sample machine cooling speed and depth can be improved, and thus the stability of the refrigeration system 2 can be improved.
