The existing fins are of a fixed structure and are not convenient for disassembly and cleaning. At the same time, the contact area between the existing fins and the outer wall of the copper pipe is small, resulting in a deviation in the heat transfer efficiency of the copper pipe. Summary of the Utility Model

During installation, align the clamping grooves on the inner side of the end plate with the vertical spacing of the coil. At this time, the extension sleeve also wraps around the outer wall of the coil. Then align and insert the two groups of insertion blocks and groove plates, and then fix them with bolts;

[0023] In this embodiment, the main frame 1 and the connecting component 2 constitute the main body structure of the commercial air conditioner heat exchanger involved in this application.

[0024] Specifically, the main frame 1 is set as two groups of parallel side plate structures, and bumps are provided at the upper and lower ends of the outer side of the side plates for easy installation and fixation.

[0025] Specifically, the clamping groove 145 is set as a semi-circular groove structure, and a thermal conductive silicone grease 1482 is also provided on the inner wall of the clamping groove 145 to improve the heat transfer efficiency.

[0026] Specifically, the second plug 21 and the inserting strip 22 are elastically connected, that is, the inserting strip 22 is made of polyurethane material. Similarly, the first plug 146 and the first groove plate 147 are elastically inserted, that is, an elastic buffer is provided inside the first groove plate 147, and a buffer pad is provided on the inner wall of the clamping groove 145.

[0027] As a preferred embodiment, by setting the elastic connection of the plug and the slot, and the buffer pad, when the fin 14 is impacted from the outside, it can have a certain elastic compressive protection effect on the coil 13.

[0028] As a preferred embodiment, by providing through holes, connection holes and threaded holes, it is convenient to fixedly connect the second plug 21 and the second groove plate 24 through the locking bolt 23.

[0029] As shown in Figures 1 to 4 The inlet end 11 and the outlet end 12 are connected to the pipeline of the air-conditioning refrigeration system, and the coil 13 is set as an S-shaped rotary pipeline structure. There is a spacing between the fins 14, and the extension sleeve 148 is in the gap. And the extension sleeve 148 is clamped on the outer wall of the coil 13. The extension sleeve 148 is set as a semi-ring sleeve structure, and the extension sleeve 148 includes a thermal conductive wall 1481 on the outside, and a thermal conductive silicone grease 1482 is provided inside the thermal conductive wall 1481.

At this time, the first insertion block, the first groove plate, the second insertion block, and the second groove plate are disengaged, and then disengaged from the coil pipe, achieving the effect of facilitating the disassembly of the fins. Furthermore, it is convenient to clean each group of fins, and to separately disassemble, replace, or repair them during later use. During installation, align the clamping grooves on the inner side of the end plate with the vertical spacing of the coil pipe for clamping. At this time, the extension sleeve liquid also wraps around the outer wall of the coil pipe. Then align and insert the two groups of insertion blocks and groove plates, and fix them with bolts. The through holes provided in the end plate facilitate the airflow blown by the cooling fan to enter the inside of the fins. Then, the airflow velocity is reduced by the zigzag plate, and the heat dissipation area of the coil pipe is increased. At the same time, the extension sleeve is clamped on the coil pipe, covering the exposed part of the coil pipe between the end plates, increasing the heat transfer area of the coil pipe, and thus improving the heat exchange efficiency of the heat exchanger.
