Fin tube

A fin tube is a type of heat exchange component used in heating and cooling systems. It consists of a metal tube with attached fins—thin, flat pieces of metal—that increase the surface area. This design helps transfer heat more efficiently between fluids inside the tube and the surrounding air or environment. Fin tubes are commonly found in radiators, air conditioners, and boilers, where they improve the system's ability to heat or cool spaces quickly and effectively by maximizing heat transfer while maintaining a compact size.
