Fin tube is a kind of heat exchange tube,by adding the fin on the surface of the tube,to increase the outer or inner area of heat tube and improve the heat exchanger efficiency. the use of base pipe sets of aluminum tube in the form, through the machine extrusion, the formation of fins, the fin base and the outer wall of the tube close together, high heat trans- fer coefficient, excellent heat transfer performance.
Main material is carbon steel/stainless/aluminum/copper and many kindsof composite material, such as copper& aluminum.The heat transfer energy is 6-10 times higher than the bare tubes.
