[0002] The fins are important components of the evaporator, which can increase the surface area and heat transfer coefficient of the evaporator, thereby improving the efficiency of the evaporator. During production and processing, they need to be processed and punched according to the installation requirements. Existing evaporator fin punching processing equipment, such as the evaporator fin punching processing equipment disclosed in application No. CN202320992789.8, includes a conveying device for conveying fins and a punching device for punching holes in the fins, and also includes a collecting device. The collecting device includes a movable base, a limit rod and a lifting platform. The fins are conveyed to the collecting device through the conveying device. The fins can be received by the lifting of the lifting platform and moved by the movable base, which can avoid the noise caused by the falling of the fins and reduce the impact.
