Its main function is to transfer heat during the refrigeration cycle, thereby achieving the temperature balance between the refrigerant and the cooling object. The heat exchanger can be installed in a limited space, which is particularly important for the design of compact refrigeration equipment. The heat exchanger assembly can be widely used in various refrigeration equipment, such as air conditioners, refrigerators, freezers, etc., and can adapt to different working environments and media, and can resist corrosion from refrigerants and the environment, thereby extending the service life of the equipment.

[0003] For example, the heat exchanger of a combined refrigeration equipment disclosed in the patent application No. CN218627361U includes a pressing plate arranged on the side of a fixing plate. A plate group is arranged between the fixing plate and the pressing plate. Both sides of the plate group are provided with a plurality of connecting rods. The connecting rod is composed of a second support rod, a first support rod, and a connecting column. The first support rod is arranged on the side of the second support rod; through the designed second support rod, first support rod, fixed clamping block, connecting column, connecting groove, and threaded groove, during the assembly process of the heat exchanger, through the second support rod, first support rod, and connecting column, the positions of the fixing plate and the pressing plate forming the heat exchanger are fixed. The lengths of the second support rod, first support rod, and connecting column can be adjusted according to requirements, improving the problem that the original screw occupies space after penetration and is somewhat dangerous for workers, thus facilitating use.

[0004] However, although the heat exchanger of the combined refrigeration equipment improves the problem of space occupation after the original screw penetrates, when the filter screen needs to be cleaned and replaced, it is not convenient to quickly disassemble the filter screen, which reduces the work efficiency to a certain extent and affects the work rhythm and efficiency.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a heat exchanger assembly for refrigeration equipment is proposed. Content of the Utility Model

[0016] 1. Through the arrangement of the limiting groove and the positioning block in the present utility model, when disassembling and replacing the filter screen, the driving motor works to drive the threaded rod to rotate.

[0025] Embodiment 1

[0026] As Figure 1 - Figure 5A heat exchanger assembly for a refrigeration device is shown, including a frame 1. Inside the frame 1, there is a heat exchange tube 2. On the frame 1, a water inlet head 3 and a drain head 4 are symmetrically arranged. The water inlet head 3 is connected to the input end of the heat exchange tube 2, and the drain head 4 is connected to the output end of the heat exchange tube 2. Inside the frame 1, support frames 5 are symmetrically arranged. Inside the support frames 5, a filter screen 6 is fixedly installed. On the support frames 5, limiting grooves 7 are symmetrically arranged. On the frame 1, a square groove 8 is fixedly installed. Inside the square groove 8, an adjustment assembly is arranged. Inside the square groove 8, a positioning assembly is arranged. The positioning assembly cooperates with the limiting grooves 7 to limit the position of the support frames 5. When using the heat exchanger assembly for a refrigeration device, after fixing the frame 1 at the heat exchange location, at the same time, the water inlet head 3 is connected to the output end of an external water delivery device through a pipeline, and the drain head 4 is connected to an external water storage assembly through a pipeline. When the gas carrying heat flows into the inside of the frame 1, it will first flow through the filter screen 6. The filter screen 6 can filter and purify the particulate matter carried by the flowing air, achieving the purpose of filtering and purifying the heat exchange gas, avoiding impurities from adsorbing on the heat exchange tube 2 and affecting the heat exchange effect of the heat exchange tube 2. When the purified air flows through the heat exchange tube 2, the heat will be transferred to the heat exchange tube 2. At the same time, when the water delivery device conveys water into the inside of the heat exchange tube 2 for flow, it will carry the heat, thereby achieving the purpose of heat exchange. The water source that has absorbed heat will be transmitted to the inside of the water storage assembly for storage through the cooperation of the drain head 4 and the pipeline. When disassembling and replacing the filter screen 6, the position of the positioning assembly will be adjusted through the adjustment assembly. After the positioning assembly moves, it will no longer position the support frames 5, and thus the filter screen 6 can be disassembled and cleaned, improving the cleaning efficiency.

[0027] Further, through grooves 9 corresponding to the limiting grooves 7 are symmetrically arranged on the square groove 8. The square groove 8 provides an installation space for the through grooves 9.

[0028] Further, the positioning assembly includes a positioning block 10 and a support plate 14. The positioning block 10 is inserted into the inside of the through groove 9. The positioning block 10 is fixedly connected to the support plate 14. The through groove 9 facilitates the sliding position of the positioning block 10. When the positioning block 10 moves, it will drive the support plate 14 to move synchronously.

[0029] Further, the positioning block 10 extends into the inside of the limiting groove 7. After the positioning block 10 moves into the inside of the limiting groove 7, the positioning block 10 cooperates with the limiting groove 7 to position the position of the support frame 5. After the positioning block 10 moves out of the inside of the limiting groove 7, the support frame 5 is no longer limited.

[0030] Further, the adjusting assembly includes a driving motor 12, a threaded rod 13 and a threaded ring 15. The driving motor 12 is fixedly installed inside the square groove 8. The threaded rod 13 is fixedly installed at the output end of the driving motor 12. The threaded ring 15 is fixedly installed inside the support plate 14, and the threaded rod 13 is threadedly connected to the threaded ring 15. When the adjusting assembly works, operating the driving motor 12 will drive the threaded rod 13 to rotate. When the threaded rod 13 rotates, the position of the threaded ring 15 will move. The movement of the threaded ring 15 will drive the support plate 14 to move synchronously. When the support plate 14 moves, it will drive the positioning block 10 to move.

[0031] Further, a battery assembly 11 is fixedly installed inside the square groove 8, and the battery assembly 11 is electrically connected to the driving motor 12. The battery assembly 11 provides power for the driving motor 12.

[0032] Further, there are two groups of support frames 5, located on one side of the heat exchange tube 2. The heat exchange tube 2 is coiled inside the frame 1. The support frame 5 is used to support the filter screen 6 and filter and protect the heat exchange tube 2.

[0033] Working principle: When using this heat exchanger assembly for a refrigeration device, first, when using the heat exchanger assembly for a refrigeration device, after fixing the frame 1 at the heat exchange location, at the same time, the water inlet head 3 is connected to the output end of an external water conveying device through a pipeline, and the drain head 4 is connected to an external water storage assembly through a pipeline. When the gas carrying heat flows into the frame 1, it will first flow through the filter screen 6. The filter screen 6 can filter and purify the particulate matter carried by the flowing air, achieving the purpose of filtering and purifying the heat exchange gas, avoiding impurities from adsorbing on the heat exchange tube 2 and affecting the heat exchange effect of the heat exchange tube 2. When the purified air flows through the heat exchange tube 2, the heat will be transferred to the heat exchange tube 2. At the same time, when the water conveying device conveys water into the heat exchange tube 2 for flow, it will carry the heat, thereby achieving the purpose of heat exchange. The water source that has absorbed heat will, through the cooperation of the drain head 4 and the pipeline, transfer the water source that has adsorbed heat to the inside of the water storage assembly for storage. When disassembling and replacing the filter screen 6, operating the driving motor 12 will drive the threaded rod 13 to rotate. When the threaded rod 13 rotates, the position of the threaded ring 15 will move. The movement of the threaded ring 15 will drive the support plate 14 to move synchronously. When the support plate 14 moves, it will drive the positioning block 10 to move. After the positioning block 10 moves out of the limit groove 7, the support frame 5 is no longer limited, and thus the filter screen 6 can be disassembled and cleaned, improving the cleaning efficiency.
