AI Technical Summary
Technical Problem
Traditional evaporator fins are prone to frost formation at low temperatures, which affects heat transfer efficiency. Existing technologies are unable to effectively remove the frost layer, leading to unstable system operation.
Method used
A heat transfer fin structure for an evaporator is designed. Through the coordinated action of a lifting component and a vibration component, the fins are dynamically adjusted and vibrated, thereby enhancing airflow disturbance, shaking off frost, increasing the heat transfer area, and preventing frost blockage.
Benefits of technology
It effectively removes frost, maintains stable heat transfer efficiency, and ensures stable system operation in low-temperature environments without requiring shutdown.

Abstract
The utility model discloses an evaporator reinforced heat transfer fin structure, include: base plate still include: rotate and install on the first fin of a plurality of equidistance distribution of base plate one side outer wall, first fin pivot one end is installed with first torsional spring, and the outer wall of both sides of base plate is installed with first frame and second frame respectively, the outer wall of first frame one side is opened with the sliding slot, and the inner wall of sliding slot is installed with lifting assembly, the outer wall of lifting assembly is installed with the connecting plate. The utility model discloses an evaporator reinforced heat transfer fin structure, through base plate conduction heat, first, second fin increases the heat transfer area. Lifting assembly drives second fin to lift, and the frost is contacted with first fin shovel and enhances the airflow disturbance, and vibration component and arc block cooperation produce vibration, and the frost layer is shaken off by the combination torsional spring reset and make fin shake. The inclined fin of up and down staggered enhances the heat transfer of convection, and the overall heat transfer efficiency is promoted, solves the frost problem, need not stop, guarantees the stable operation of system.
