Description

Technical Field

[0001] This utility model relates to the field of fin repair technology, specifically a radiator fin repair device. Background Technology

[0002] Evaporators, condensers, and coils are commonly used heat exchange components in air conditioners. These components are made by punching and drilling holes in fins, arranging them neatly, then inserting copper tubes through the holes, expanding the tubes, and fixing them into shape. Because the fins are only 1mm thick and have low hardness, they are prone to bending. Newly manufactured radiators often have their fin surfaces damaged during handling and assembly.

[0003] A search revealed a utility model patent with patent authorization announcement number CN208042868U, which discloses a fin repair brush, including a brush body and a brush head. The brush head includes multiple metal wires, one end of which is fixed to one end of the brush body, and the other end of which is bent downward and fixed to a square plate. The other ends of all the metal wires are arranged parallel to each other on the same plane, and all the plates are arranged parallel to each other on the same plane.

[0004] However, existing radiator fin repair devices have poor applicability due to the different spacing of radiator fins. Utility Model Content
