[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to Chinese Patent Application No. 2024117501400, filed on November 29, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of refrigeration technology, and in particular relates to a refrigeration device and a method for assembling the refrigeration device. Background Technology

[0004] In related technologies, refrigeration equipment includes an inner liner and an outer shell, and a refrigeration system is used to cool the compartment formed by the inner liner. Since the refrigeration system includes multiple refrigeration components such as an evaporator, heat exchanger, condenser, and compressor, these components are connected by heat exchange tube assemblies filled with refrigerant, allowing the refrigerant to circulate among the components to achieve a cooling effect.

[0005] The spacing between different heat exchange tubes, as well as the fixing and installation of the heat exchange tubes themselves, play a crucial role in the stable operation of refrigeration equipment. However, due to the large length-to-diameter ratio of some heat exchange tubes, it is difficult to maintain the preset state stably, resulting in different performance of different prototypes during mass production, which requires improvement. Summary of the Invention

[0006] This application aims to address at least one of the technical problems existing in the prior art.

[0101] 6. Outer shell. Detailed Implementation

[0102] 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.

[0103] The following is for reference. Figures 1-23 This application describes a refrigeration device and a method for assembling the refrigeration device according to embodiments of the present application.

[0104] 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.

[0105] The refrigeration equipment includes a cabinet and a door. The cabinet includes an outer shell 6, an inner liner 1, and an insulation layer located between the outer shell 6 and the inner liner 1. The outer shell 6 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 6 and the inner liner 1 forms a machine compartment, which is used to house machines such as compressors and circuit breakers.

[0106] like Figures 1-3 As shown in the figure, the refrigeration equipment of this application embodiment includes: a refrigeration system 2 and a mounting bracket assembly.

[0107] 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.

[0108] 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 6, 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.

[0109] The mounting bracket assembly can be installed on the casing of the refrigeration equipment. For example, the mounting bracket assembly can be installed on the inner liner 1, the outer shell 6, or clamped between the inner liner 1 and the outer shell 6. The specific configuration can be determined according to the installation process.

[0110] The mounting bracket assembly forms multiple mounting positions 322, which include multiple sets arranged at intervals along the thickness direction, each set being used to fix a layer of heat exchange tube assembly 21.

[0111] The mounting bracket assembly is used to fix the heat exchange tube assembly 21, improve the stability of the heat exchange tube assembly 21 when installed on the outside of the inner tank 1, and improve the stability of the operation of the refrigeration system 2.

[0112] like Figure 1 As shown, multiple mounting positions 322 are formed on the mounting bracket assembly. These mounting positions 322 include multiple sets arranged at intervals along the thickness direction of the inner liner 1, each set being used to fix one layer of heat exchange tube assembly 21, and multiple sets of mounting positions 322 being used to fix the multi-layer heat exchange tube assembly 21 arranged along the thickness direction.

[0113] The mounting bracket assembly may include a variety of mounting brackets with different structures, and one or a combination of different mounting brackets may be used to fix the heat exchange tube assembly 21 in different directions.

[0114] For example, the multi-layer heat exchange tube group 21 distributed along the thickness direction can be supported and fixed, or multiple tube segments of the same layer heat exchange tube group 21 distributed laterally can be supported and fixed, or multiple tube segments of the same layer heat exchange tube group 21 distributed vertically can be supported and fixed.

[0115] According to the refrigeration equipment provided in this application, by setting up the mounting bracket assembly, the multi-layer heat exchange tube assembly 21 distributed along the thickness direction can be fixed, thereby reducing the shaking or deformation of the multi-layer heat exchange tube assembly 21 distributed along the thickness direction during operation. This reduces the variation in the spacing of the multi-layer heat exchange tube assembly 21 along the thickness direction, improves the stability of the spacing between each layer of heat exchange tubes, and achieves a more uniform cooling effect. At the same time, since the mounting bracket assembly can be mass-produced, by setting up the mounting bracket assembly, the heat exchange tube assembly 21 in multiple mass-produced refrigeration equipment of the same model can be located in a predetermined position, thereby improving the consistency of performance during prototype mass production, increasing the pass rate of prototype cooling speed and depth, and thus improving the stability of the refrigeration system 2.

[0116] In some embodiments, the refrigeration equipment further includes a housing, which forms a compartment, and the refrigeration system 2 and mounting bracket assembly are both installed in the housing. The housing includes an inner liner 1 and an outer shell 6, the inner liner 1 forming a compartment, and the inner liner 1 being disposed within the outer shell 6.

[0117] 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.

[0118] The mounting locations for the mounting bracket assembly include at least the following three types:

[0119] Firstly, both the mounting bracket assembly and the heat exchange tube assembly 21 are installed in the inner liner.

[0120] like Figure 1 As shown, the mounting bracket assembly can be connected to the inner liner 1 by snap-fit, welding, abutment, screwing, or plugging.

When the refrigeration equipment is horizontal, the opening 11 of the inner liner 1 faces upward, the first connecting piece is located at the bottom of the inner liner 1, and the mounting bracket assembly can be connected to the first connecting piece at the bottom of the inner liner 1. When the refrigeration equipment is vertical, the opening 11 of the inner liner 1 faces forward, the first connecting piece is located at the rear end of the inner liner 1, and the mounting bracket assembly can be connected to the first connecting piece at the rear end of the inner liner 1.

[0127] In the assembly process of this embodiment, the mounting bracket assembly is first assembled onto the heat exchange tube assembly 21, then the heat exchange tube assembly 21 with the mounting bracket assembly is assembled onto the inner liner 1, then the inner liner 1 with the heat exchange tube assembly 21 and the mounting bracket assembly is assembled onto the outer shell 6, and then foaming is performed.

[0128] Secondly, both the mounting bracket assembly and the heat exchange tube assembly 21 are installed on the outer casing 6.

[0129] The mounting bracket assembly can be connected to the housing 6 via snap-fit, welding, abutment, or plug-in connection.

[0130] In some embodiments, the mounting bracket assembly is connected to the side plate of the housing 6.

[0131] The refrigeration equipment can be horizontal or vertical. When the refrigeration equipment is horizontal, the mounting bracket assembly is connected to any one or more of the four side plates of the outer casing 6 (front, back, left, and right). When the refrigeration equipment is vertical, the mounting bracket assembly is connected to any one or more of the four side plates of the outer casing 6 (upper, lower, left, and right).

[0132] In some embodiments, such as Figures 20-23 As shown, the inner liner 1 has an opening 11, and the mounting bracket assembly can be connected to the end of the side plate of the outer shell 6 on the same side as the opening 11; or, the mounting bracket assembly can also be connected to the end of the side plate of the outer shell 6 away from the opening 11.

[0133] The mounting bracket assembly can be connected to the end of the housing on the same side as the opening 11; or, the end of the housing on the same side as the opening 11 is provided with a connector, and the mounting bracket assembly can be connected to the connector.

[0134] The refrigeration equipment can be horizontal or vertical. When the refrigeration equipment is horizontal, the opening 11 of the inner liner 1 faces upward, and the mounting bracket assembly can be connected to the upper end of the outer shell 6. When the refrigeration equipment is vertical, the opening 11 of the inner liner 1 faces forward, and the mounting bracket assembly can be connected to the front end of the outer shell 6.

[0135] In some embodiments, the inner liner 1 has an opening 11, and a mounting bracket assembly is connected to the outer shell 6 on a plate opposite to the opening 11.

[0136] The refrigeration equipment can be horizontal or vertical. When the refrigeration equipment is horizontal, the opening 11 of the inner liner 1 faces upward, and the mounting bracket is connected to the bottom plate of the outer shell 6. When the refrigeration equipment is vertical, the opening 11 of the inner liner 1 faces forward, and the mounting bracket is connected to the rear plate of the outer shell 6.

[0137] In some embodiments, such as Figures 20-23 As shown, the inner liner 1 has an opening 11, and the outer shell 6 has a second connector on its bottom plate away from the opening 11. The mounting bracket assembly is connected to the second connector.

[0143] In some embodiments, the mounting bracket assembly may abut against the outer shell 6, or the mounting bracket assembly may abut against the inner liner 1; or the mounting bracket assembly may abut against both the outer shell 6 and the inner liner 1.

[0144] The heat exchange tube assembly 21 is spaced apart from the outer shell 6 to increase safety and reduce heat loss.

[0146] During installation, the inner liner 1 can be installed into the outer shell 6 first, and then the heat exchange tube assembly and mounting bracket assembly can be vertically lowered into the gap between the inner liner 1 and the outer shell 6 to complete the welding. Then the cabinet opening can be installed, and then foaming can be performed.

[0147] In some embodiments, such as Figures 20-23 As shown, the inner liner 1 has an opening 11, through which the heat exchange tube assembly 21 with the mounting bracket assembly can be assembled between the outer shell 6 and the inner liner 1 from the direction of the opening 11.

[0148] The refrigeration equipment can be horizontal or vertical, such as... Figure 20 As shown, when the refrigeration equipment is horizontal, the opening 11 of the inner liner 1 faces upward, and the heat exchange tube assembly 21, equipped with mounting brackets, can be inserted from top to bottom between the inner liner 1 and the outer shell 6; as Figure 22 As shown, when the refrigeration equipment is vertical, the opening 11 of the inner liner 1 faces forward, and the heat exchange tube assembly 21 with the mounting bracket can be inserted from front to back between the inner liner 1 and the outer shell 6.

[0149] In some embodiments, the inner liner 1 has an opening 11, and a heat exchange tube assembly 21 with a mounting bracket assembly can be assembled between the outer shell 6 and the inner liner 1 from a direction away from the opening 11.

[0150] The refrigeration equipment can be horizontal or vertical, such as... Figure 21 As shown, when the refrigeration equipment is horizontal, with the opening 11 of the inner liner 1 facing upwards, the heat exchange tube assembly 21, equipped with mounting brackets, can be inserted from bottom to top between the inner liner 1 and the outer shell 6; as Figure 23 As shown, when the refrigeration equipment is vertical, the opening 11 of the inner liner 1 faces forward, and the heat exchange tube assembly 21 with the mounting bracket can be inserted from back to front between the inner liner 1 and the outer shell 6.

[0151] In some embodiments, the outer shell 6 includes a side wall and a plate body facing away from the inner liner opening 11. First, the side wall of the outer shell 6 is assembled with the inner liner 1. Then, the heat exchange tube assembly 21 with the mounting bracket assembly is assembled between the outer shell 6 and the inner liner 1. Finally, the plate body facing away from the inner liner opening 11 is connected to the side wall of the outer shell 6.

[0152] like Figure 1 As shown, in some embodiments, the heat exchange tube assembly 21 includes, in at least a portion of the region, a serpentine tube segment 211 extending along a first direction, wherein the first direction is perpendicular to the thickness direction and is the extension direction of the serpentine tube segment 211 after multiple bends, and multiple tube segments of the serpentine tube segment 211 are distributed in the first direction.

[0153] In this embodiment, the heat exchange tube assembly 21 effectively increases the heat exchange area by setting serpentine tube segments 211, thereby improving the refrigeration efficiency; and the distribution of serpentine tube segments 211 can extend the arrangement area of ​​the heat exchange tube assembly 21, avoiding local overheating or overcooling; and the design of serpentine tube segments 211 can arrange more heat exchange tubes in a limited space, improving the space utilization and refrigeration effect of the refrigeration equipment.

[0154] like Figure 1 As shown, the mounting bracket assembly extends along the first direction, and the mounting bracket assembly extends along the first direction of the serpentine pipe section 211 to firmly support the entire serpentine pipe section 211 and reduce the shaking and deformation of the multiple pipe sections in the serpentine pipe section 211.

[0155] like Figure 2 As shown, the mounting bracket group includes at least one mounting bracket, and multiple mounting positions 322 of the same group on the same mounting bracket are distributed along the first direction, and are used to position multiple pipe segments 211 distributed along the first direction.

[0156] In this application, multiple mounting positions 322 for positioning the serpentine pipe segment 211 distributed along the first direction are provided on the mounting bracket. Compared with the structure of fixing the multiple pipe segments of the serpentine pipe segment 211 with multiple mounting parts, this application can simplify the installation steps of the mounting bracket, reduce the number of mounting brackets, and improve the support effect of the mounting bracket on the multiple pipe segments of the serpentine pipe segment 211.

[0157] In some embodiments, such as Figures 3-9 As shown, the mounting bracket includes: a mounting base 31, a connecting part 33, and multiple clamping parts 32.

[0158] like Figure 4 As shown, the mounting base 31 extends along the first direction, and the connecting part 33 and multiple clamping parts 32 are all mounted on the mounting base 31. The mounting base 31 plays a role in bearing and fixing the multiple clamping parts 32. The mounting base 31 can be arranged along the extension direction of the serpentine pipe section 211.

[0159] The shape of the mounting base 31 can be a straight line, an arc, or other shape suitable for the layout of the serpentine pipe segment 211, extending along the first direction.

[0160] like Figure 3 As shown, multiple sets of clamping members 32 are disposed on at least one side of the mounting base 31 along the thickness direction, and the clamping members 32 form mounting positions 322.

[0161] Among them, such as Figure 3 and Figure 6 As shown, multiple sets of clamping members 32 can be disposed on one or both sides of the mounting base 31 along the thickness direction.

[0162] For example, such as 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.

[0163] 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.

[0164] The mounting base 31 is connected to the housing via the connecting part 33, which can be connected to the housing by means of threaded connection, welding, snap-fit, or abutment. For example, the mounting base 31 can be connected to the inner liner 1 and / or the outer shell 6 via the connecting part 33.

[0165] In some embodiments, the connecting part 33 has a slot 331 for engaging with the housing of the refrigeration equipment. The connecting part 33 and the housing have at least three installation methods:

[0166] Firstly, when the mounting base 31 is connected to the inner liner 1 via the connecting part 33, such as Figure 5 and Figure 7 As shown, the connecting part 33 has a slot 331, which is used to engage with the end of the inner liner 1.

[0167] The sides and bottom of the inner liner 1 have overlapping extensions, which can improve the stability of the connection between the sides and bottom of the inner liner 1, thereby improving the overall sealing performance of the inner liner 1.

[0168] The groove 331 of the connecting part 33 matches the shape of the end of the inner liner 1 so that the connecting part 33 engages with the inner end.

[0169] In this embodiment, the snap-fit ​​method between the slot 331 and the end of the inner liner 1 greatly simplifies the assembly process and improves production efficiency. Furthermore, the installation of the mounting bracket and the inner liner 1 does not require the use of additional fasteners (such as screws, nuts, etc.), which reduces assembly time and cost.

[0170] Secondly, when the mounting base 31 is connected to the housing 6 via the connecting part 33, the connecting part 33 may have a slot 331 for engaging with the end of the housing 6.

[0171] The side surface and bottom surface of the outer casing 6 have overlapping extensions that can extend toward the interior of the outer casing 6, thereby improving the stability of the connection between the side surface and the bottom surface of the outer casing 6.

[0172] The groove 331 of the connecting part 33 matches the shape of the end of the housing 6 so that the connecting part 33 engages with the inner end of the extension of the housing 6, thereby positioning the mounting bracket assembly.

[0173] In this embodiment, the snap-fit ​​connection between the slot 331 and the housing 6 greatly simplifies the assembly process and improves production efficiency. Furthermore, the installation of the mounting bracket and the housing 6 does not require the use of additional fasteners (such as screws, nuts, etc.), which reduces assembly time and cost.

[0174] Third, when the mounting bracket assembly is located between the outer shell 6 and the inner liner 1, the connecting part 33 can be provided on both sides of the mounting base 31 along the thickness direction, and the connecting part 33 abuts against the outer shell 6 and the inner liner 1 respectively.

[0175] In this embodiment, the mounting bracket assembly is sandwiched between the outer shell 6 and the inner liner 1. The mounting base 31 is provided with connecting portions 33 on both sides along the thickness direction, thereby extending the thickness of the mounting base 31 and increasing the stability of the position of the mounting bracket assembly between the outer shell 6 and the inner liner 1.

[0176] In some embodiments, the mounting base 31 is provided with a plurality of clamping members 32 distributed in a first direction, and the connecting portion 33 is provided at the end of the mounting base 31 along the first direction.

[0177] Among them, such as Figure 5 As shown, multiple clamping members 32 are arranged along a first direction; as Figure 7 As shown, multiple clamping members 32 are disposed in two layers along the thickness direction of the mounting base 31, and multiple clamping members 32 in the same layer are arranged along the first direction.

[0178] like Figure 5 and Figure 7 As shown, the slot 331 is provided at the end of the mounting base 31 along the first direction to facilitate installation with the housing.

[0179] In some embodiments, the slot 331 is open in a first direction toward the direction where the clamping member 32 is provided, so that the slot 331 can be directly engaged with the end of the housing.

[0180] In some embodiments, the slot 331 is open in a first direction toward the direction in which the clamping member 32 is provided, so that the slot 331 can be inserted into the housing along the insertion direction of the mounting bracket assembly.

[0181] In some embodiments, the mounting base 31 is provided with a plurality of clamping members 32 distributed in a first direction, and the connecting portion 33 is provided at the end of the mounting base 31 along the first direction, so as to facilitate the installation of the mounting bracket and the housing, and at the same time improve the stability of the connection between the mounting bracket and the housing.

[0182] In some embodiments, the clamping member 32, the mounting base 31, and the connecting portion 33 are distributed along the thickness direction of the mounting bracket.

[0183] Among them, such as Figure 5 As shown, the clamping member 32, the mounting base 31, and the connecting part 33 are distributed sequentially along the thickness direction of the mounting bracket. The connecting part 33 protrudes from the mounting base 31 along the thickness direction of the mounting bracket to facilitate the installation of the mounting bracket and the housing, and at the same time improve the stability of the connection between the mounting bracket and the housing.

[0184] Among them, such as Figure 7 As shown, the clamping members 32 are respectively disposed on both sides of the mounting base 31 along the thickness direction. That is, the clamping members 32, the mounting base 31, the clamping members 32 and the connecting part 33 are distributed sequentially along the thickness direction of the mounting bracket. The connecting part 33 protrudes from the mounting base 31 along the thickness direction of the mounting bracket to facilitate the installation of the mounting bracket and the box, and at the same time improve the stability of the connection between the mounting bracket and the box.

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] The gripper 321 can have a certain degree of elasticity to accommodate changes in the shape and size of the heat exchange tube when gripping it. This elastic design can reduce pressure concentration on the heat exchange tube and avoid damage.

[0190] The shape and size of the flange 323 can be optimized according to the shape and size of the heat exchange tube. For example, for a circular heat exchange tube, the flange 323 can be designed as an arc or a cone to better fit the surface of the heat exchange tube. For heat exchange tubes of other shapes, the flange 323 can also be adjusted accordingly.

[0191] In some embodiments, such as Figure 9 As shown, the flange 323 is inclined toward the mounting base 31 to guide the heat exchange tube, making it easier for the heat exchange tube to be placed into the mounting position 322 and less likely to fall off the mounting position 322. This helps to simplify the assembly of the heat exchange tube and the mounting bracket and improve the stability of the heat exchange tube.

[0192] In some embodiments, such as Figure 8 As shown, the mounting bracket also includes a first reinforcing part 34, which is connected between the side wall of the gripper 321 and the mounting base 31. The first reinforcing part 34 is used to enhance the connection strength between the gripper 321 and the mounting base 31, and reduce the risk of the gripper 321 breaking or loosening at the connection due to excessive force when clamping the heat exchange tube.

[0193] The shape and size of the first reinforcing part 34 can be adjusted according to the shape and size of the gripper 321 and the mounting base 31, as well as the desired reinforcing effect.

[0194] For example, the first reinforcing part 34 can be designed as a triangle, rectangle or other shape with good stability.

[0195] like Figure 7 As shown, the mounting bracket also includes a second reinforcing part 35, which is connected between the flange 323 and the mounting base 31, and at least a portion of the second reinforcing part 35 is spaced apart from the side wall of the gripper 321.

[0196] The second reinforcing part 35 is used to enhance the connection strength between the flange 323 and the mounting base 31, while avoiding excessive constraint or interference on the side wall of the gripper 321. By setting them at intervals, the elasticity of the gripper 321 can be improved, so that the gripper 321 can maintain sufficient flexibility and adaptability when clamping the heat exchange tube.

[0197] The shape and size of the second reinforcing part 35 can also be adjusted according to the shape and size of the flange 323 and the mounting base 31, as well as the desired reinforcement effect. For example, the second reinforcing part 35 can be designed as an arc, trapezoid, or other shape to accommodate the tilt and bending of the flange 323.

[0198] In this embodiment, by providing the first reinforcing part 34 and the second reinforcing part 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 tube and the vibration and impact generated during refrigerant circulation; and the design of the reinforcing part helps to disperse and balance the stress distribution on the mounting bracket, reduce damage caused by stress concentration, and extend the service life of the mounting bracket and the refrigeration equipment.

[0199] In some embodiments, the mounting bracket includes a second reinforcing portion 35 connected between the flange 323 and the mounting base 31, and at least a portion of the second reinforcing portion 35 is spaced apart from the sidewall of the gripper 321.

[0200] The second reinforcing part 35 is used to enhance the connection strength between the flange 323 and the mounting base 31, while avoiding excessive constraint or interference on the side wall of the gripper 321. By setting them at intervals, the elasticity of the gripper 321 can be improved, so that the gripper 321 can maintain sufficient flexibility and adaptability when clamping the heat exchange tube.

[0201] The shape and size of the second reinforcing part 35 can also be adjusted according to the shape and size of the flange 323 and the mounting base 31, as well as the desired reinforcement effect. For example, the second reinforcing part 35 can be designed as an arc, trapezoid, or other shape to accommodate the tilt and bending of the flange 323.

[0202] In some embodiments, the mounting bracket further includes a first reinforcing portion 34, which is connected between the side wall of the gripper 321 and the mounting base 31.

[0203] The shape and size of the first reinforcing part 34 can be adjusted according to the shape and size of the gripper 321 and the mounting base 31, as well as the desired reinforcing effect.

[0204] For example, the first reinforcing part 34 can be designed as a triangle, rectangle or other shape with good stability.

[0205] The mounting bracket also includes a second reinforcing part 35 connected between the flange 323 and the mounting base 31, and at least a portion of the second reinforcing part 35 is spaced apart from the side wall of the gripper 321.

[0206] In some embodiments, such as Figure 7 As shown, the width of the slot opening of the slot 331 is greater than the width of the bottom of the slot 331, that is, the slot opening of the slot 331 forms a guide surface, and the slot opening of the slot 331 forms an outwardly bent guide surface, so as to facilitate the assembly of the slot 331 with the end of the inner liner 1 or the end of the outer shell 6.

[0207] In some embodiments, such as Figure 3 and Figure 4As shown, the mounting base 31 is provided with a plurality of first weight-reducing grooves 311, which are arranged at intervals along the extension direction of the mounting base 31; and / or, the mounting base 31 is provided with a plurality of first through holes 312.

[0208] In this embodiment, the mounting base 31 is provided with multiple first weight-reducing grooves 311 and / or multiple first through holes 312. Under the premise of meeting structural strength and stability, the weight of the mounting base 31 can be reduced, the utilization of materials can be optimized, and the foaming material can flow through the first through holes 312 during the filling of foaming material between the inner liner 1 and the outer shell 6. This improves the stability of the combination between the mounting base 31 and the foaming material, thereby improving the positional stability of the mounting bracket, thus improving the support and fixing effect of the mounting bracket on the heat exchange tube assembly 21, and improving the stability of the refrigeration equipment.

[0209] The shape of the first weight-reducing groove 311 can be designed as a circle, ellipse, rectangle or other shapes according to actual needs.

[0210] Multiple first weight-reducing grooves 311 are arranged at intervals along the extension direction of the mounting base 31 to achieve weight reduction while maintaining the overall stability of the structure.

[0211] In this embodiment, the design of the first weight-reducing groove 311 significantly reduces the weight of the mounting base 31, helping to reduce the overall weight and cost of the refrigeration equipment. By rationally designing the shape and arrangement of the first weight-reducing groove 311, material utilization can be optimized and improved while maintaining structural strength. The first weight-reducing groove 311 can also increase the stability of the bonding between the mounting base 31 and the foaming material, thereby improving the support and fixation effect of the mounting bracket on the heat exchange tube assembly 21 and enhancing the stability of the refrigeration equipment.

[0212] The first through hole 312 can be circular, square, or other shapes, depending on the design requirements and processing capabilities.

[0213] During the process of filling the foam material between the inner liner 1 and the outer shell 6, it is convenient for the foam material to flow from the first through hole 312, which improves the stability of the bonding between the mounting base 31 and the foam material, thereby improving the positional stability of the mounting bracket, thus improving the support and fixing effect of the mounting bracket on the heat exchange tube assembly 21, and improving the stability of the refrigeration equipment.

[0214] In some embodiments, the mounting base 31 is provided with a plurality of first weight-reducing grooves 311, which are spaced apart along the extending direction of the mounting base 31.

[0215] The shape of the first weight-reducing groove 311 can be designed as a circle, ellipse, rectangle or other shapes according to actual needs.

[0216] Multiple first weight-reducing grooves 311 are arranged at intervals along the extension direction of the mounting base 31 to achieve weight reduction while maintaining the overall stability of the structure.

[0217] In this embodiment, the design of the first weight-reducing groove 311 significantly reduces the weight of the mounting base 31, helping to reduce the overall weight and cost of the refrigeration equipment. By rationally designing the shape and arrangement of the first weight-reducing groove 311, material utilization can be optimized and improved while maintaining structural strength. The first weight-reducing groove 311 can also increase the stability of the bonding between the mounting base 31 and the foaming material, thereby improving the support and fixation effect of the mounting bracket on the heat exchange tube assembly 21 and enhancing the stability of the refrigeration equipment.

[0218] In some embodiments, such as Figure 5 and Figure 6 As shown, the mounting base 31 is provided with a plurality of first through holes 312.

[0219] The first through hole 312 can be circular, square, or other shapes, depending on the design requirements and processing capabilities.

[0220] When foam material is filled between the inner liner 1 and the outer shell 6, it facilitates the flow of foam material from the first through hole 312, improves the stability of the connection between the mounting base 31 and the foam material, thereby improving the positional stability of the mounting bracket, thus improving the support and fixing effect of the mounting bracket on the heat exchange tube assembly 21, and improving the stability of the refrigeration equipment.

[0221] The mounting bracket assembly may include at least a portion of the first mounting bracket 36, the second mounting bracket 37, and the third mounting bracket 38, and combinations thereof.

[0222] The first mounting bracket 36 is used to position the heat exchange tube assembly 21 near the inner liner 1; the second mounting bracket 37 is used to position the heat exchange tube assembly 21 near the inner liner 1 and the heat exchange tube assembly 21 away from the inner liner 1; the third mounting bracket 38 is used to position the heat exchange tube assembly 21 near the inner liner 1, and to position the heat exchange tube assembly 21 near the inner liner 1 and part of the transfer pipe 215 away from the inner liner 1; and the fourth mounting bracket is used to position the heat exchange tube assembly 21 away from the inner liner 1.

[0223] The following examples illustrate some implementation methods for the above types of mounting brackets.

[0224] In some embodiments, such as Figure 4 and Figure 5 As shown, the mounting bracket assembly includes at least one first mounting bracket 36, and a plurality of mounting positions 322 on the first mounting bracket 36 are in the same group along the thickness direction.

[0225] The first mounting bracket 36 is used to fix the heat exchange tube group 21 in the same layer, and multiple mounting positions 322 can be set on the same side of the mounting base 31 of the first mounting bracket 36.

[0226] For example, when the first mounting bracket 36 is installed between the inner liner 1 and a heat exchange tube assembly 21 near the inner liner 1, the first mounting bracket 36 can be used to position the heat exchange tube assembly 21 near the inner liner 1.

[0227] For example, when the first mounting bracket 36 is installed between the housing 6 and a heat exchange tube assembly 21 near the housing 6, the first mounting bracket 36 can be used to position the heat exchange tube assembly 21 near the housing 6.

[0228] For example, when the first mounting bracket 36 is installed between a heat exchange tube assembly 21 near the inner liner 1 and a heat exchange tube assembly 21 away from the inner liner 1, the first mounting bracket 36 can be used to position the heat exchange tube assembly 21 away from the inner liner 1 or the heat exchange tube assembly 21 near the inner liner 1, depending on the orientation of the first mounting bracket 36.

[0229] In some embodiments, such as Figure 1 As shown, the refrigeration system 2 also includes an evaporator 22 wound around the inner liner 1 of the refrigeration equipment. The mounting base 31 of the first mounting bracket 36 abuts against the evaporator 22 on the side opposite to the corresponding clamp 32. Thus, when the first mounting bracket 36 is installed between the evaporator 22 and a layer of heat exchange tubes 21 near the inner liner 1, the first mounting bracket 36 can limit the distance between the evaporator 22 and the layer of heat exchange tubes 21 near the inner liner 1.

[0230] In this embodiment, the evaporator 22 wrapped around the inner liner 1 can provide multi-point support for the support base of the first mounting bracket 36, thereby improving the stability of the position of the first mounting bracket 36.

[0231] In some embodiments, such as Figure 6 and Figure 7 As shown, the mounting bracket assembly includes a second mounting bracket 37, and the multiple clamping members 32 of the second mounting bracket 37 include a first group 371 and a second group 372, which are respectively disposed on both sides of the mounting base 31 along the thickness direction.

[0232] The second mounting bracket 37 can position two adjacent heat exchange tube groups 21 distributed along the thickness direction.

[0233] The first group 371 and the second group 372 both include multiple mounting positions 322. Multiple mounting positions 322 in the same group are used to fix the same layer of heat exchange tube group 21, and multiple mounting positions 322 in different groups are used to fix different layers of heat exchange tube group 21 distributed along the thickness direction.

[0234] The mounting base 31 of the second mounting bracket 37 is located between two adjacent heat exchange tube groups 21, which can limit the distance between the two adjacent heat exchange tube groups 21.

[0235] In some embodiments, such as Figure 6 and Figure 7 As shown, the second mounting bracket 37 also includes at least one first support portion 373, which protrudes from the mounting base 31 and is higher than the clamping member 32, and abuts against the housing.

[0236] For example, when the second mounting bracket 37 is mounted upright, the first support portion 373 faces the inner liner 1 and abuts against the inner liner 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 liner 1.

[0237] For example, such as Figure 1 and Figure 3 As shown, when the second mounting bracket 37 is installed in reverse, the first support portion 373 faces the outer shell 6. The first support portion 373 can abut against the outer shell 6 to support the second mounting bracket 37 and improve the stability of the relative position between the second mounting bracket 37, the inner liner 1 and the outer shell 6.

[0238] The first support portion 373 may include multiple portions, which are spaced apart along the extension direction of the second mounting bracket 37 to provide multi-point support for the second mounting bracket 37.

[0239] In some embodiments, such as Figure 8 and Figure 9 As shown, the mounting bracket assembly includes at least one third mounting bracket 38, a 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 the multilayer heat exchange tube assembly 21.

[0240] The third mounting bracket 38 is used to fix the heat exchange tube assembly 21 on the same layer, and at the same time, it is used to fix the connecting pipes between different refrigeration components. The connecting pipes can be located on different layers from the fixed heat exchange tube assembly 21.

[0241] In practical use, the refrigeration system 2 includes a heat exchanger, a regenerator, an evaporator 22, and an evaporator-condenser.

[0242] The evaporator and condenser are distributed laterally, and the heat exchanger and regenerator are stacked at intervals along the thickness direction. The evaporator 22 is wrapped around the outer wall of the inner liner 1.

[0243] The heat exchanger includes a first serpentine tube section and a first connecting section, the first serpentine tube section extending along a first direction and the first serpentine tube section and the first connecting section being distributed laterally.

[0244] The regenerator includes a second serpentine tube section and a second connecting section, the second serpentine tube section extending along a first direction and the second serpentine tube section and the second connecting section being distributed laterally.

[0245] The evaporator-condenser includes a third serpentine tube section and a third connecting section. The third connecting section is located laterally between the third serpentine tube section and the first serpentine tube section. The third serpentine tube section extends in a first direction, and the third serpentine tube section and the third connecting section are distributed laterally.

[0246] A portion of the evaporator 22, a portion of the regenerator, and a portion of the heat exchanger are distributed along the direction from the inner liner 1 to the outer shell 6. A portion of the evaporator 22 and a portion of the evaporator-condenser are distributed along the direction from the inner liner 1 to the outer shell 6.

[0247] The first mounting bracket 36 is disposed between the evaporator 22 and the regenerator to fix the distance between the regenerator and the evaporator 22, and at the same time to stabilize the stability of each section of the second serpentine tube section of the regenerator.

[0248] The second mounting bracket 37 is disposed between the evaporator 22 and the outer casing 6 to simultaneously fix the distance between the regenerator and the evaporator 22, and between the regenerator and the heat exchanger. It can also simultaneously position the stability of each section of the second serpentine tube segment of the regenerator and the stability of each section of the first serpentine tube segment of the heat exchanger.

[0249] The third mounting bracket 38 is disposed between the evaporator 22 and the evaporator-condenser to fix the distance between the evaporator-condenser and the evaporator 22, and to stabilize the stability of each section of the third serpentine tube segment of the evaporator-condenser. It can also fix the connecting pipe between the evaporator-condenser and the heat exchanger. The connecting pipe is located on the side of the evaporator-condenser away from the evaporator 22 along the thickness direction.

[0250] In some embodiments, such as Figure 1 and Figure 3 As shown, the heat exchange tube assembly 21 is arranged in at least a portion of the area as multiple tube sections 212 spaced apart laterally; the refrigeration equipment also includes a fixing bracket 4, which forms multiple fixing positions 422, including multiple sections spaced apart laterally, each for fixing a section of tube 212.

[0251] For example, the multiple tube segments 212 of the heat exchange tube assembly 21, which are spaced apart laterally, can be multiple tube segments 212 of the same refrigeration component, such as the heat exchange portion and connecting portion of a heat exchanger, the heat exchange portion and connecting portion of a regenerator, or the heat exchange portion and connecting portion of an evaporator-condenser; or, the multiple tube segments 212 of the heat exchange tube assembly 21, which are spaced apart laterally, can be multiple tube segments 212 of different refrigeration components, such as the heat exchange portion of a heat exchanger and the connecting portion of an evaporator-condenser.

[0252] Multiple tube sections 212 can be straight or curved. The fixing bracket 4 is used to fix the spacing between adjacent tube sections 212 or non-adjacent tube sections in the multiple tube sections 212 distributed laterally, so as to support the weight of the entire heat exchange tube assembly 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 tube assembly 21 in the refrigeration equipment, and thus improving the stability of the refrigeration system 2.

[0253] The number of fixed supports 4 can be distributed according to the length and number of heat exchange tubes 21. For example, multiple fixed supports 4 can be distributed to form multi-point positioning and support, thereby improving the lateral positioning and support effect of heat exchange tubes 21.

[0254] In this embodiment, as Figure 1 , Figure 3 and Figure 11 As shown, the mounting bracket assembly and the fixing bracket 4 work together. The mounting bracket assembly can position and support the multi-layer heat exchange tubes of the heat exchange tube assembly 21 spaced apart along the thickness direction, and position the serpentine tube segments 211 extending vertically in the same layer of heat exchange tubes. The fixing bracket 4 can position and support the multi-section tubes 212 distributed laterally in the same layer of heat exchange tube assembly 21. Thus, the tube segments distributed in the lateral, vertical, and thickness directions of the heat exchange tube assembly 21 can be positioned and supported to support the weight of the entire heat exchange tube assembly 21 and resist the vibration and stress generated by the refrigeration system 2 during operation. This can improve the stability of the spacing between adjacent tube segments of the heat exchange tube assembly 21 distributed in the lateral, vertical, and thickness directions, thereby improving the uniformity of the heat exchange temperature of the heat exchange tube assembly 21, improving the pass rate of the prototype cooling speed and depth, and thus improving the stability of the refrigeration system 2.

[0255] The size and shape of the fixing position 422 are matched with the heat exchange tube assembly 21 to improve the fixing and support effect of the tube section 212. In this way, each tube section 212 can be independently and stably supported, thereby avoiding displacement or deformation caused by vibration or temperature changes, thus improving the stability of the spacing between adjacent tube sections 212, and thus improving the spacing between the multiple tube sections 212 distributed laterally in the heat exchange tube assembly 21, so that the multiple tube sections 212 distributed laterally all meet the preset heat exchange design.

[0256] In addition, the number and position of the fixing positions 422 can be adjusted according to the specific heat exchange tube group 21 design and cooling requirements to achieve the best fixing effect and heat exchange performance.

[0257] Among them, such as Figure 11 As shown, the fixing bracket 4 can be installed on the inner liner 1, the outer shell 6, or clamped between the inner liner 1 and the outer shell 6. Alternatively, the fixing bracket 4 can also be installed on the heat exchange tube assembly 21. The fixing bracket 4 is installed and the heat exchange tube assembly 21 is positioned by positioning and assembling with the heat exchange tube assembly 21.

[0258] In some embodiments, the heat exchange tube assembly 21 includes, in at least a portion of the region, serpentine tube segments 211 and connecting segments 213 distributed laterally.

[0259] The serpentine tube segments 211 and connecting segments 213 that are distributed laterally and are adjacent to each other can belong to the same refrigeration component or to different refrigeration components; the serpentine tube segments 211 and connecting segments 213 that are distributed laterally and are adjacent to each other can also be in the same layer along the thickness direction or be in different layers along the thickness direction.

[0260] At least a portion of the serpentine pipe segment 211 and at least a portion of the connecting segment 213 may extend along a first direction and be distributed laterally. A plurality of mounting positions 322 on the fixed bracket 4 are distributed laterally for positioning and supporting the positions and spacing of adjacent serpentine pipe segments 211 and connecting segments 213.

[0261] In this embodiment, the heat exchange tube assembly 21 effectively increases the heat exchange area by setting serpentine tube segments 211, thereby improving the refrigeration efficiency; and the distribution of serpentine tube segments 211 can extend the arrangement area of ​​the heat exchange tube assembly 21, avoiding local overheating or overcooling; and the design of serpentine tube segments 211 can arrange more heat exchange tubes in a limited space, improving the space utilization and refrigeration effect of the refrigeration equipment.

[0262] The connecting section 213 can be used to connect the serpentine pipe section 211 with other pipe sections.

[0263] For example, the end of the heat exchanger connection section 213 away from the serpentine tube section 211 can be used to connect the first condenser and the first compressor; the end of the heat exchanger connection section 213 away from the serpentine tube section 211 can be used to connect the second condenser and the second compressor; the end of the evaporator condenser connection section 213 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.

[0264] like Figure 11 , Figure 12 and Figure 13As shown, the fixed bracket 4 extends laterally, and multiple mounting positions 322 on the same fixed bracket 4 are distributed laterally and used to position adjacent serpentine pipe sections 211 and connecting sections 213.

[0265] Adjacent serpentine tube segments 211 and connecting segments 213 can be in the same layer along the thickness direction of the heat exchange tube group 21, or they can be in different layers along the thickness direction.

[0266] In some embodiments, such as Figure 11 , Figure 12 and Figure 13 As shown, the fixed bracket 4 includes a fixed base 41 and multiple fixing parts 42.

[0267] The fixing seat 41 extends laterally and serves to support and fix multiple fixing elements 42.

[0268] Multiple fasteners 42 are disposed on at least one side of the fixing base 41 along the thickness direction. The multiple fasteners 42 can be disposed on one or both sides of the fixing base 41 along the thickness direction to fix one or more layers of the heat exchange tube assembly 21 along the thickness direction.

[0269] Among them, the fastener 42 forms the fixed position 422.

[0270] For example, such as Figure 15 and Figure 16 As shown, when multiple fasteners 42 can be provided on one side of the fixing base 41 along the thickness direction, if a set of fasteners 42 is provided on one side of the fixing base 41 along the thickness direction, the fixing bracket 4 can fix and support the serpentine pipe segments 211 and connecting segments 213 distributed in the same layer, thereby limiting the lateral spacing of the serpentine pipe segments 211 and connecting segments 213 distributed in the same layer; if multiple sets of fasteners 42 distributed along the thickness direction are provided on one side of the fixing base 41 along the thickness direction, the lateral spacing of the serpentine pipe segments 211 and connecting segments 213 in different layers along the thickness direction can be limited, as well as the lateral spacing of the serpentine pipe segments 211 and connecting segments 213 in the same layer can be limited.

[0271] like Figure 11 , Figure 12 and Figure 13 As shown, when multiple sets of fasteners 42 are provided on both sides of the fixing base 41 along the thickness direction, the fixing bracket 4 can at least fix and support the adjacent layer serpentine tube segments 211 and connecting segments 213 distributed along the thickness direction in the transverse direction, which limits the spacing of different layers of heat exchange tube groups 21 along the thickness direction, and also limits the spacing of the same layer serpentine tube segments 211 and connecting tubes in the transverse direction.

[0272] In some embodiments, such as Figure 11 and Figure 16As shown, the fixing member 42 includes two fixing claws arranged opposite each other. One end of the fixing claws is connected to the fixing base 41. The two fixing claws of the fixing member 42 form a bent portion 421 that bends toward each other at the end away from the fixing base 41. The two fixing claws arranged opposite each other form a fixing position 422.

[0273] The design of the bend 421 increases the contact area between the fixing claw and the heat exchange tube, improving the stability and reliability of clamping. At the same time, the bend 421 also serves as a guide and positioner, 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 fixing position 422.

[0274] Two opposing fixing claws form a fixing position 422, which is used to accommodate and fix the heat exchange tube. By adjusting the spacing between the fixing claws and the shape of the bend 421, heat exchange tubes of different diameters and shapes can be accommodated.

[0275] The retaining claws can have a certain degree of elasticity to accommodate changes in the shape and size of the heat exchange tube when clamping it. This elastic design can reduce pressure concentration on the heat exchange tube and prevent damage.

[0276] The shape and size of the bend 421 can be optimized according to the shape and size of the heat exchange tube. For example, for a circular heat exchange tube, the bend 421 can be designed as an arc or a cone to better fit the surface of the heat exchange tube. For heat exchange tubes of other shapes, the bend 421 can also be adjusted accordingly.

[0277] In some embodiments, the bend 421 is inclined toward the fixing seat 41 to guide the heat exchange tube, making it easier for the heat exchange tube to be placed into the fixing position 422 and less likely to fall off from the fixing position 422. This helps to simplify the assembly of the heat exchange tube and the fixing bracket 4 and improve the stability of the heat exchange tube.

[0278] In some embodiments, such as Figure 11 , Figure 12 and Figure 13 As shown, the fixed bracket 4 also includes a reinforcing member 43, which is connected between the bent portion 421 and the fixed base 41, and at least a portion of the reinforcing member 43 is spaced apart from the side wall of the fixed claw.

[0279] The reinforcing member 43 enhances the connection strength between the bent portion 421 and the fixed base 41, while avoiding excessive constraint or interference on the sidewalls of the fixing claw. The spaced arrangement improves the elasticity of the fixing claw, allowing it to maintain sufficient flexibility and adaptability when clamping the heat exchange tube.

[0280] The shape and size of the reinforcing member 43 can also be adjusted according to the shape and size of the bent portion 421 and the fixing seat 41, as well as the desired reinforcement effect. For example, the reinforcing member 43 can be designed as an arc, trapezoid, or other shape to accommodate the tilt and bending of the bent portion 421.

[0281] In this embodiment, by providing the reinforcing member 43, the overall strength and stability of the fixed bracket 4 can be improved, so that the fixed bracket 4 can better withstand the weight of the heat exchange tube and the vibration and impact generated during refrigerant circulation; and the design of the reinforcing part helps to disperse and balance the stress distribution on the fixed bracket 4, reduce damage caused by stress concentration, and extend the service life of the fixed bracket 4 and the refrigeration equipment.

[0282] In some embodiments, such as Figure 11 , Figure 12 and Figure 13 As shown, the fixing base 41 is provided with a plurality of second weight reduction grooves 44, which are arranged at intervals along the extension direction of the fixing base 41, and the fixing base 41 is provided with a plurality of second through holes 46.

[0283] In this embodiment, the fixing base 41 is provided with multiple second weight-reducing grooves 44 and / or multiple second through holes 46. Under the premise of meeting structural strength and stability, the weight of the fixing base 41 can be reduced, the utilization of materials can be optimized, and the foaming material can flow through the second through holes 46 during the filling of foaming material between the inner liner 1 and the outer shell 6. This improves the stability of the combination between the fixing base 41 and the foaming material, thereby improving the positional stability of the fixing bracket 4. This improves the support and fixing effect of the fixing bracket 4 on the heat exchange tube assembly 21, and improves the stability of the refrigeration equipment.

[0284] The shape of the second weight-reducing groove 44 can be designed as a circle, ellipse, rectangle or other shapes according to actual needs.

[0285] 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.

[0286] 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.

[0287] The second through hole 46 can be circular, square, or other shapes, depending on the design requirements and processing capabilities.

[0288] During the process of filling the foam material between the inner liner 1 and the outer shell 6, 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.

[0289] In some embodiments, such as Figure 13 As shown, the mounting base 41 is provided with multiple second through holes 46.

[0290] The second through hole 46 can be circular, square, or other shapes, depending on the design requirements and processing capabilities.

[0291] During the process of filling the foam material between the inner liner 1 and the outer shell 6, 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.

[0292] 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.

[0293] The shape of the second weight-reducing groove 44 can be designed as a circle, ellipse, rectangle or other shapes according to actual needs.

[0294] 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.

[0295] 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.

[0296] 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.

[0297] 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 6 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.

[0298] 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.

[0299] The fixing bracket 4 includes at least two of the following structures:

[0300] 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.

[0301] 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.

[0302] 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.

[0303] like Figure 14 As shown, the fixing bracket 4 includes multiple brackets, at least one of which is used to position one of the two serpentine pipe segments 211 and the connecting segment 213, and at least another of which is used to position the other of the two serpentine pipe segments 211 and the connecting segment 213.

[0304] In this embodiment, multiple fixing positions 422 distributed laterally on the fixing bracket 4 are used to fix the serpentine pipe segments 211 and connecting segments 213 distributed laterally. Multiple fixing brackets 4 are used to fix multiple serpentine pipe segments 211 and multiple connecting segments 213. By setting multiple fixing brackets 4, the heat exchange tube group 21 can be supported at multiple points laterally, thereby improving the stability of the spacing between multiple pipe segments in the heat exchange tube group 21 laterally, thereby improving the consistency of the cooling rate of the heat exchange tube group 21 laterally.

[0305] Secondly, such as Figure 11 , Figure 12 and Figure 13 As shown, the multiple fixing positions 422 include multiple groups distributed along the thickness direction. The multiple groups of fixing positions 422 are distributed along the thickness direction of the fixing bracket 4. Each group of fixing positions 422 includes multiple fixing positions 422 distributed along the transverse direction.

[0306] The fixed bracket 4 is used to fix and position the heat exchange tube assembly 21, which is distributed along the thickness direction and laterally.

[0307] In this embodiment, the heat exchange tube assembly 21 is arranged in multiple layers along the thickness direction in at least a portion of the area; multiple fixing positions 422 on the fixing bracket 4 are arranged in multiple groups spaced apart along the thickness direction, and multiple fixing positions 422 in different groups on the same fixing bracket 4 are distributed along the thickness direction and are used to position the multi-layer heat exchange tube assembly 21.

[0308] Among them, multiple fixing positions 422 of different groups are arranged on the fixing bracket 4 to facilitate fixing the heat exchange tube group 21 arranged along the thickness direction and reduce the assembly difficulty.

[0309] For example, the fixed position 422 of the alignment setting can be used to fix the adjacent two sides of the serpentine pipe segment 211, or the adjacent two sides of the connecting segment 213, or the adjacent two sides of the serpentine pipe segment 211 and the connecting segment 213.

[0310] In some embodiments, such as Figure 11 , Figure 12 and Figure 13 As shown, the fixing bracket 4 also includes a snap-fit ​​portion 45, which protrudes along the thickness direction of the fixing seat 41. When the snap-fit ​​portion 45 is located on the side facing the inner liner 1, the snap-fit ​​portion 45 abuts against the inner liner 1 to provide additional support and stability for the fixing bracket 4.

[0311] For example, the snap-fit ​​part 45 can abut against one side of the inner liner 1 along the lateral direction to limit the fixing bracket 4 in the lateral direction, thereby limiting the heat exchange tube assembly 21 in the lateral direction and improving the stability of the heat exchange tube assembly 21 in the lateral direction; the snap-fit ​​part 45 can abut against one side of the inner liner 1 along the vertical direction to limit the fixing bracket 4 in the vertical direction, thereby limiting the heat exchange tube assembly 21 in the vertical direction and improving the stability of the heat exchange tube assembly 21 in the vertical direction.

[0312] In this embodiment, the inner liner 1 abuts against the snap-fit ​​part 45, which can reduce the possibility of damage to the heat exchange tube assembly 21 due to movement or vibration during installation and use.

[0313] In practical use, the refrigeration system 2 includes a heat exchanger and a regenerator. The heat exchanger and the regenerator are distributed along the thickness direction. The regenerator and the evaporator-condenser are distributed in the transverse direction. Both the regenerator and the regenerator include a serpentine tube section 211 and a connecting section 213 distributed in the transverse direction. The projection of the serpentine tube section 211 along the thickness direction falls within the projection of the inner liner 1 along the thickness direction. The projection of the connecting section 213 along the thickness direction is located outside the projection of the inner liner 1 along the thickness direction.

[0314] The fixing bracket 4 with snap-fit ​​part 45 can be used to fix the heat exchanger and the regenerator. The multiple fixing positions 422 distributed laterally on the fixing bracket 4 with snap-fit ​​part 45 can fix the serpentine tube section 211 and the connecting section 213 of the regenerator. The multi-layer fixing positions 422 distributed along the thickness direction on the fixing bracket 4 with snap-fit ​​part 45 can fix the serpentine tube section 211 of the regenerator and the serpentine tube section 211 of the regenerator. The snap-fit ​​part 45 abuts against the inner liner 1 or the outer shell 6 to limit the heat exchanger and the regenerator laterally.

[0315] In some embodiments, such as Figure 17 As shown, the refrigeration system includes an evaporator 22 and a heat exchange tube assembly 21. The heat exchange tube assembly 21 includes a capillary tube 214. The evaporator 22 is wound around the outer side of the inner liner 1. The refrigeration equipment also includes a support bracket 5, which supports the evaporator 22. The support bracket 5 is provided with an annular support position 512, and the capillary tube 214 is wound around the annular support position 512.

[0316] According to the refrigeration equipment provided in the embodiments of this application, by setting a support bracket 5, which is used to position the capillary tube 214, the distance between the capillary tube 214 and the evaporator 22, the distance between the capillary tube 214 and the inner liner 1 or the outer shell 6, and the distance between the capillary tube 214 and the outer shell 6 are limited, thereby reducing the influence of the temperature of the inner liner 1, the evaporator 22 and the outer shell 6 on the temperature of the capillary tube 214. Since the support bracket 5 can be mass-produced, by setting the support bracket 5, the capillary tube 214 in multiple mass-produced refrigeration equipment of the same model can be located in a predetermined position, thereby improving the consistency of performance when the prototype is mass-produced.

[0317] In this embodiment, as Figure 1 , Figure 2 and Figure 17As shown, the support bracket 5, the mounting bracket group, and the fixed bracket 4 work together to position each tube segment within the heat exchange tube group 21. This ensures that the multi-layer heat exchange tubes along the transverse direction, the serpentine tube segments 211 and connecting segments 213 distributed along the transverse direction within the same layer, the serpentine tube segments 211 extending along the first direction within the same layer, and the capillary tubes 214 are all positioned. This allows the heat exchange tube group 21 in multiple mass-produced refrigeration devices of the same model to be located in the predetermined position, thereby improving the consistency of performance during prototype mass production, enhancing the reliability of the refrigeration system 2 in each refrigeration device, and extending the service life of the refrigeration device.

[0318] One side of the support bracket 5 is supported by the evaporator 22, and the other side can be supported by the outer shell 6 or spaced apart from the outer shell 6. The support bracket 5 is pre-assembled with the capillary tube 214 before filling with foam material.

[0319] The evaporator 22 is wound around the inner liner 1. The evaporator 22 is used to absorb heat and achieve a cooling effect on the compartment formed by the inner liner 1.

[0320] like Figure 18 and Figure 19 As shown, the annular bearing position 512 on the bearing support 5 is used to wind the capillary tube 214 in an orderly manner, thereby forming a compact and efficient capillary tube 214 heat exchange tube group 21, which improves the throttling effect.

[0321] The annular design of the annular bearing 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.

[0322] In some embodiments, such as Figure 2 and Figure 3 As shown, the support bracket 5 includes a winding base 51, and the outer peripheral wall of the winding base 51 forms an annular support position 512.

[0323] The winding base 51 is the core component of the support bracket 5, and its shape and structure are crucial to the performance and stability of the entire refrigeration equipment. In this embodiment, the winding base 51 is designed to have an outer peripheral wall, which forms an annular support position 512.

[0324] In some embodiments, such as Figure 18 and Figure 19 As shown, the outer peripheral wall of the winding base 51 is provided with baffles 511 at both ends along the axial direction. The baffles 511 extend around the circumference of the winding base 51, and the baffles and the outer peripheral wall of the winding base 51 form an annular bearing position 512.

[0325] 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 the winding process and operation, and to increase the number of winding layers of the capillary tube 214 along the axial direction at the annular bearing position 512.

[0326] Among them, the baffle 511 extends along the outer peripheral wall of the winding base 51. The baffle 511 can extend along the circumference of the winding base 51 to form a complete ring structure, or the baffle 511 can extend along the circumference of the winding base 51 to form a multi-segment arc structure.

[0327] In this embodiment, the baffle 511 not only provides a physical barrier for the capillary 214, but also increases the friction between the capillary 214 and the winding base 51 through its close fit design, making the capillary 214 more stable after winding. At the same time, the baffle 511 can make the winding base 51 and the foamed insulation layer form an interlocking structure after foaming, improving the bonding strength and thus improving the positional stability of the winding base 51.

[0328] In some embodiments, such as Figure 18 and Figure 19 As shown, the flange 511 includes multiple flanges, which are located at the same end and are spaced apart around the circumference of the winding base 51. The flanges 511 also extend along the circumference of the winding base 51 to form a multi-segment arc structure.

[0329] In this embodiment, the multi-segment design of the retaining edge 511 structure can reduce material costs and form an interlocking structure with the insulation layer to improve the bonding strength, thereby improving the positional stability of the winding base 51.

[0330] In some embodiments, the flanges 511 located at different ends are staggered, which can further form an interlocking structure with the insulation layer, improve the bonding strength, and thus improve the positional stability of the support bracket 5.

[0331] In some embodiments, such as Figure 18 and Figure 19 As shown, the flange 511 located at the end of the winding base 51 away from the inner liner 1 is provided with a through hole 5111. The through hole 5111 can be used to assemble with the outer shell 6, or to form an interlocking structure with the insulation layer to improve the bonding strength.

[0332] In some embodiments, the inner wall of the winding base 51 is provided with an inwardly protruding reinforcing rib 513. The retaining edge 511 and the reinforcing rib 513 are respectively disposed 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 insulation layer to improve the bonding strength.

[0333] Among them, the reinforcing rib 513 can extend around the circumference of the base 51 to form a ring-shaped reinforcing structure, or it can include multiple reinforcing ribs 513 distributed at intervals around the circumference of the base 51.

[0334] In some embodiments, such as Figure 18 and Figure 19 As shown, the inner wall of the winding base 51 is provided with at least one inwardly protruding reinforcing rib 513. 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.

[0335] In some embodiments, the side of the spokes 52 facing away from the inner liner 1 is not higher than the side of the winding base 51 facing away from the inner liner 1, so as to reduce the installation difficulty of installing the support bracket 5 between the inner liner 1 and the outer shell 6.

[0336] In some embodiments, such as Figure 2 and Figure 3 As shown, the support bracket 5 also includes spokes 52, the ends of which are connected to the winding base 51.

[0337] The spokes 52 provide additional support and stability to the winding base 51. Through their design of being connected to the winding base 51, the spokes 52 can effectively distribute and bear the weight and stress from the winding base 51 and the capillary 214 on it, thereby improving the load-bearing capacity and stability of the entire support bracket 5. At the same time, it can also improve the structural strength of the support bracket 5 and reduce the deformation of the support bracket 5 during the foaming process.

[0338] The spokes 52 and the winding base 51 can be connected by welding, bolting or integral molding to improve the stability of the connection between the spokes 52 and the winding base 51, thereby reducing the possibility of the capillary 214 loosening or falling off due to the deformation of the support bracket 5 during use.

[0339] The hub is formed by winding the base 51, and the spokes 52 include multiple spokes that extend radially from the hub to the rim. The number, shape, and layout of the spokes can be adjusted according to application requirements.

[0340] Since multiple spokes extend radially from the center of the hub to the rim, and at least part of the spacing between adjacent spokes can form an interlocking structure with the insulation layer, the bonding strength is improved and the risk of deformation of the support 5 during the foaming process is reduced.

[0341] In some embodiments, such as Figure 18 and Figure 19 As shown, the spokes 52 are provided with a third weight-reducing groove 521, which is arranged along the extension direction of the spokes 52.

[0342] The shape of the third weight-reducing groove 521 can be designed as a circle, ellipse, rectangle or other shapes according to actual needs.

[0343] Multiple third weight-reducing grooves 521 are arranged at intervals along the extension direction of the spokes 52 to achieve weight reduction while maintaining the overall stability of the structure.

[0344] In this embodiment, the design of the third weight-reducing groove 521 significantly reduces the weight of the spokes 52, helping to reduce the overall weight and cost of the refrigeration equipment. By rationally designing the shape and arrangement of the third weight-reducing groove 521, material utilization can be optimized and improved while maintaining structural strength. The third weight-reducing groove 521 can also increase the stability of the bond between the spokes 52 and the foaming material, thereby improving the support and fixation effect of the bearing base on the capillary tube 214 and enhancing the stability of the refrigeration equipment.

[0345] In some embodiments, the spokes 52 protrude axially from the support bracket 5 on the side facing the inner liner 1, and the spokes 52 abut against the evaporator 22 on the side facing the inner liner 1.

[0346] Among them, a flexible layer can be provided on the side of the spoke 52 facing the inner liner 1. The flexible layer can be plastic, rubber, etc., to protect the evaporator 22.

[0347] In this embodiment, by providing spokes 52 protruding from the support bracket 5, the support bracket 5 and the evaporator 22 can be limited, increasing the distance between the support bracket 5 and the evaporator 22, and reducing the influence of the evaporator 22 or the inner liner 1 on the temperature of the capillary tube 214.

[0350] According to the refrigeration equipment provided in this application, by setting the fixed bracket 4, the multiple tube sections 212 of the heat exchange tube group 21 distributed laterally in the same layer can be positioned and supported, which can improve the stability of the spacing between adjacent tube sections of the heat exchange tube group 21 distributed laterally, thereby improving the uniformity of the heat exchange temperature of the heat exchange tube group 21. At the same time, since the fixed bracket 4 can be mass-produced, by setting the fixed bracket 4, the heat exchange tube group 21 in multiple mass-produced refrigeration equipment of the same model can be located in a predetermined position, thereby improving the consistency of performance during prototype mass production, improving the pass rate of prototype cooling speed and depth, and thus improving the stability of the refrigeration system 2.

[0353] According to the refrigeration equipment provided in the embodiments of this application, by setting a support bracket 5, which is used to position the capillary tube 214, the distance between the capillary tube 214 and the evaporator 22, the distance between the capillary tube 214 and the inner liner 1, and the distance between the capillary tube 214 and the outer shell 6 is limited, thereby reducing the influence of the temperature of the inner liner 1, the evaporator 22 and the outer shell 6 on the temperature of the capillary tube 214. Since the support bracket 5 can be mass-produced, by setting the support bracket 5, the capillary tube 214 in multiple mass-produced refrigeration equipment of the same model can be located in a predetermined position, thereby improving the consistency of performance during prototype mass production, improving the pass rate of prototype cooling speed and depth, and thus improving the stability of the refrigeration system 2.
