The high-frequency welded finned tube is a disadvantage of a heat sink made of a string type and a wound fin, and an improved heat-dissipating element using a high-frequency welded finned tube is improved, and the finned tube itself has a thickness of 0.8. -1mm strip is wound on the finned tube, and the high-frequency welding process is used to weld the sheet to the tube to ensure the bonding strength between the tube and the fin. The metal thermal strength has reached 1.10~1.20w/kg°C. The finned tube is widely used in the economizer of the boiler, the production and workshop of the air preheater, the production of the energy-saving radiator of the house, and the first choice for the heat treatment of the heat pipe.
The spiral finned tube is a highly efficient heat transfer element. Its heat transfer area is several times to several tens of times of the light pipe, which can enhance heat transfer, reduce flow resistance and reduce metal consumption, thereby improving the economic efficiency and operational reliability of the heat exchange equipment. At present, spiral finned tubes have been widely used in various boilers.
