[0002] In the prior art, the heat exchange fin group is one of the important components in the evaporator and the condenser, and its performance directly affects the overall efficiency of the evaporator and the condenser.

[0003] Existing heat exchange fins usually have corrugations on the heat exchange fin body to increase the contact area between the air and the heat exchange tubes, thereby improving the heat exchange efficiency. However, in actual implementation, turbulence will be generated when the air enters the corrugated heat exchange fin group, thereby increasing the thermal resistance of the air, resulting in reduced heat exchange efficiency and the heat exchanger cannot meet the needs of rapid cooling. Furthermore, in order to meet the installation requirements of the heat exchange fins, the corrugated heat exchange fins are usually only provided with corrugations on one side of the heat exchange fin body, so that the heat exchange fin group needs to be installed corresponding to the air inlet direction during the installation process, which increases the difficulty of installation. Therefore, improvements are urgently needed. Utility Model Content
