The 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. The factory can also process high-frequency welded steel finned tubes and copper-aluminum composite finned tubes according to user needs.
The high frequency welded finned tube is a new type of efficient heat exchange element.
It is a disadvantage of a heat sink made of string-type and wound fins, and improves a high-efficiency heat-dissipating component using a high-frequency welded finned tube. The finned tube itself is wound around a finned tube. At the same time, the high-frequency welding process is adopted to weld the sheet to the tube to ensure the bonding strength between the tube and the fin. The heat exchange efficiency is high, the heat dissipation area is large, the service life is long, the temperature range is wide, and the pressure is high. .
The main advantages of high-frequency welded finned tube are: 1 high production efficiency, continuous winding production; 2 low cost, it relies on the characteristics of high-frequency welding itself - skin effect to heat the surface of the workpiece to achieve the purpose of welding, welding process There is no need to add any filler metal material; 3 because the high-frequency current only passes through the shallow surface of the steel pipe, the welding heat affected zone is small, so the design calculation does not need to consider the additional wall thickness; the workpiece does not need to be welded after welding. Heat treatment; 4 welding is reliable, in the case of reasonable equipment configuration, perfect process parameters, the welding between the fin and the steel pipe can be achieved firmly, and can withstand the thermal shock fluctuation caused by frequent opening and stopping. Because high-frequency welded finned tubes have the above advantages, they are more and more widely used in new high-efficiency heat transfer elements in petroleum, chemical, electric power and other industries to enhance heat transfer outside the tube, improve heat recovery efficiency, and save energy. The purpose of reducing consumption.
