When operating at low temperature, the fin heat exchangers will appear frost / icing phenomenon due to low air temperature. Generally, two methods are used for defrosting, one is four-way valve reversing for defrosting, and the other is hot gas bypass defrosting.

[0003] In the prior art, the screw type air-cooled unit usually has a bypass defrosting fin heat exchanger when in use. The fin heat exchanger is composed of fin heat exchange gas pipe, fin heat exchange liquid pipe, exhaust pipe, frame plate and joint elbow pipe. Therefore, when using the fin heat exchanger, the fin heat exchanger needs to be assembled with the screw type air-cooled unit, and then the heat source generated by the screw type air-cooled unit enters the fin heat exchanger through the fin heat exchange gas pipe of the fin heat exchanger. The heat source generated by the screw type air-cooled unit can be dissipated through the heat dissipation of the fin heat exchanger itself and the fan of the heat exchanger. However, when the fin heat exchanger is assembled with the screw type air-cooled unit, the fin heat exchanger must be moved by a crane due to its heavy weight. The crane is composed of a bottom plate and a traction rope. When the crane moves the fin heat exchanger, the fin heat exchanger will deviate from the position of the bottom plate. SUMMARY
