Spiral Wound Finned Tube

High frequency welding finned tube radiator for string type and winding type fin made of the shortcomings, and improved by high frequency welding is an efficient heat radiating element of finned tube, fin tube itself is the strip thickness 0.8-1mm winding in the finned tube, and the high-frequency welding process, the welding in tablets pipe, ensure the bonding strength of tube and fin, the metal heat intensity reached 1.10 1.20w/kg degrees centigrade, widely used in boiler economizer of the finned tube air preheater and production workshop, production of residential energy-saving radiator, and heat pipe as the late winding preferred.

Spiral finned tube is an efficient heat transfer device. Its heat transfer area is several times to several times, it can strengthen heat transfer, reduce the flow resistance, reduce metal consumption, so as to improve the economic and operational reliability of heat exchange equipment. At present, the spiral finned tube has been widely used in various boilers.

The structure of the spiral finned tube is shown as the figure above.
