Serrated finned tube
The serrated finned tube is also called segmented finned tube. it is to open the teeth of the steel strip before the welding of the fins, and then use the skin effect of the high-frequency current to weld the toothed steel strip to the steel tube. The finned tube produced by this process has high welding fastness and good heat exchange efficiency. In addition, after the fins are toothed, the turbulence effect is increased, which improves the heat exchange efficiency and can better prevent dust accumulation.
