[0046] The use of mounting screws 222 simplifies the installation and removal process, requiring no complicated tools or skills and reducing maintenance costs.

[0047] Example 3

[0048] To improve the efficiency of assembling and disassembling the cooling pipes with other components used to connect them, such as Figures 2 to 4 As shown, in this embodiment, the cooling pipe 11 is designed with pure copper material. Heat sinks 112 are welded at equal intervals on the outer wall of the cooling pipe 11 on the opposite side of the two mounting brackets 2. The two ends of the cooling pipe 11 pass through the mounting groove 211 and are connected to the first connecting flange 111. The two cooling pipes 11 that are furthest apart and diagonally opposite each other are connected to the same side end of the liquid inlet and outlet pipes 13.

[0049] In the design, pure copper has excellent thermal conductivity, which can efficiently transfer heat and improve the evaporator's cooling efficiency.

[0050] The heat sink 112 increases the contact area between the cooling pipe 11 and the air, improves the heat exchange efficiency, and helps to dissipate heat quickly.

[0051] The flange connection ensures a tight connection between the cooling pipes 11 to prevent refrigerant leakage; the design of the inlet and outlet liquid pipes 13 allows the refrigerant to flow smoothly into and out of the evaporator.

[0052] Furthermore, the heat sink 112 adopts a ring structure design, and the wall thickness of the heat sink 112 matches the wall thickness of the cooling pipe 11.

[0053] In the design, the annular heat sink 112 can be evenly distributed around the cooling pipe 11, improving the uniformity and efficiency of heat exchange.

[0054] The wall thickness of the heat sink 112 matches the wall thickness of the cooling pipe 11, ensuring the integrity and strength of the structure and avoiding thermal stress problems caused by differences in wall thickness.

[0055] Further, the inlet and outlet pipe 13 is designed with stainless steel material, and a third connecting flange 131 is installed in communication on the inlet and outlet pipe 13, and the inlet and outlet pipe 13 is installed in communication with the cooling pipe 11 farthest apart and diagonally through the first connecting flange 111 and the third connecting flange 131.

[0056] In the design, the stainless steel inlet and outlet pipe 13 has the characteristics of corrosion resistance, high strength and long service life, and can withstand the pressure and temperature changes of the refrigerant.

[0057] The flange connection ensures the close connection between the inlet and outlet pipe 13 and the cooling pipe 11, prevents refrigerant leakage, and improves the reliability, disassembly convenience and safety of the system.

[0058] Further, the communication elbow pipe 12 is designed with stainless steel material, and a second connecting flange 121 is installed in communication on both ends of the communication elbow pipe 12, and the adjacent cooling pipe 11 is installed in communication with the communication elbow pipe 12 through the first connecting flange 111 and the second connecting flange 121.

[0059] In the design, the stainless steel communication elbow pipe 12 has the characteristics of corrosion resistance, high strength and long service life, and can withstand the pressure and temperature changes of the refrigerant while maintaining the stability and reliability of the structure.

[0060] The flange connection ensures the close connection between the communication elbow pipe 12 and the cooling pipe 11, prevents refrigerant leakage, and improves the overall performance, disassembly convenience and safety of the system.

[0061] When disassembling the utility model: first, prepare the required tools, including screwdrivers, wrenches, etc., for disassembling and installing the screws 222. Use a screwdriver to loosen the mounting screws 222 on the clamping frame 22. Since the mounting screws 222 pass through the second nut column 221 and are threadedly connected with the first nut column 212, after loosening the screws, the clamping frame 22 can be separated from the positioning bracket 21. After the clamping frame 22 is removed, the evaporator coil 1 part of the evaporator coil 1 will no longer be clamped. At this time, the evaporator coil 1 can be carefully pulled out of the mounting groove 211 of the positioning bracket 21. Since the two ends of the cooling pipe 11 pass through the mounting grooves 211 of the two positioning brackets 21 respectively, the entire evaporator coil 1 can be taken out completely. If further maintenance or replacement of the evaporator coil 1 is required, the inlet and outlet pipe 13 also needs to be disconnected. This involves disassembling the third connecting flange 131 on the inlet and outlet pipe 13 and the first connecting flange 111 connected with the cooling pipe 11, and then repairing or replacing the damaged components of the evaporator coil 1.

[0062] The utility model installs: ensure that the cooling pipe 11 is intact after maintenance, all the connecting flanges and the pipeline have been installed correctly. The inlet and outlet liquid pipe 13 is installed in communication with the two cooling pipes 11 farthest apart and diagonal through the third connecting flange 131 and the first connecting flange 111. Ensure that the connection is tight and has no leakage. The two ends of the cooling pipe 11 pass through the installation slot 211 of the two positioning supports 21 respectively. Ensure that the cooling pipe 11 is correctly placed in the installation slot 211, and the cooling fin 112 maintains appropriate distance with the positioning support 21. The adjacent cooling pipe 11 is installed in communication with the communication elbow pipe 12 using the second connecting flange 121 and the first connecting flange 111. Ensure that all the connections are tight and have no leakage. The clamping frame 22 is placed at the open end of the positioning support 21, and the first nut column 212 is screwed with the second nut column 221 using the installation screw 222. Ensure that the clamping frame 22 is firmly fixed on the positioning support 21, and clamps the assembled evaporator coil 1. After completing the installation, carefully check whether all the connection points are tight and have no leakage. Then, necessary test is carried out to ensure that the evaporator coil 1 works normally.

[0063] It is obvious for those skilled in the art that the utility model is not limited to the details of the above-mentioned exemplary embodiments, and the utility model can be realized in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point, the embodiments should be regarded as exemplary and non-restrictive, the scope of the utility model is defined by the appended claims instead of the above description, therefore, all the changes falling within the meaning and scope of the equivalent elements of the claims should be included in the utility model.
