[0002] Fins are commonly used heat exchange components in heat exchangers. Their primary function is to increase the heat exchange area, thereby improving heat transfer efficiency. Fins are attached to the surface of pipes to increase the surface area in contact with the fluid, thereby enhancing heat transfer efficiency. Fins are typically formed into the desired fin shape by stamping or pressing metal sheets using dies. The stamped fins are then conveyed to assembly and press-fitting equipment for subsequent processing.
