Introduction：The heating element of the air duct type electric heater is a stainless steel electric heating tube. The inner chamber of the heater is equipped with a number of baffles (deflectors) to guide the flow of gas and extend the residence time of gas in the inner chamber, so that the gas can be fully heated, the gas can be heated evenly, and the heat exchange efficiency can be improved
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.
