What is a High Frequency Spiral Fin Tube Welded Machine?
High frequency spiral fin tube welded machine is a device used to manufacture high frequency welded fin tubes. High frequency welded fin tubes are fin tubes made by high frequency current welding technology, mainly used to improve heat exchange efficiency.
Working principle of spiral tube finning welding machine
The working principle of high frequency fin tube welded machine is to use the skin effect and proximity effect of high frequency current to heat the outer surface of steel strip and steel tube, and then complete the welding under a certain pressure, so that the base tube and the fin are basically integrated.

The characteristics of high frequency fin tube welded machine include:
High efficiency welding : High frequency fin tube welded machine uses high frequency current for electric welding, which can increase the tightness of the radiator and improve the safety of operation.
High quality welding : The heat generated during the welding process heats the surface of the steel strip to a molten state, and the welding is completed under a certain pressure. The welding method is reliable and the welding strength is high.
Widely used: High-frequency welded finned tubes are widely used in waste heat recovery, petrochemical, boiler, wood drying and other systems, and are favored for their high heat exchange efficiency, large heat conduction range and durability.
High-frequency finned tube welded machines have a wide range of applications, especially in industrial and mechanical control. For example, in chemical plants, high-frequency welded finned tube radiators are used as temperature control artifacts to ensure stable operation and efficient heat dissipation of equipment.
