[0002] Fin heat exchangers are highly efficient heat exchange devices widely used in air conditioning, refrigeration, and industrial cooling systems. They consist of multiple parallel fins and a base tube. The fins are typically made of metal and increase heat transfer efficiency by increasing surface area.

[0004] However, when the fins are welded to the base tube, the fins tend to wobble, and the relative positions of the fins and the base tube need to be adjusted repeatedly, resulting in an inconvenient installation of the fins. Utility Model Content
