High frequency welding spiral finned tubular heater is a kind of spiral finned heater element widely used at present. It is a kind of heat dissipation element improved by high frequency welding for the shortcomings of serial fin and wound fin.
Finned air heater is a kind of element suitable for radiators, because of its good heat transfer, it is loved by consumers. The following HVAC exhibition will introduce the advantages and classification of finned heater element for you, let's take a look.
The basic characteristics of high-frequency welded finned heater are: (1) efficient production, can be continuously wound; 2) The cost is low, which lies in the characteristics of high-frequency welding - the workpiece is welded on the hot surface.In order to achieve a strong welding effect, there is no need to add alloy metal materials during the welding process.3) Because the high-frequency current only passes through the outer surface of the steel pipe, the influence range of welding heat is small, and the increase of wall thickness is not considered in the formulation calculation; No heat treatment is required after welding; (4) Welding firmness. When the facilities are properly prepared and the process data is perfect, the welding process of the tube fins is reliable and can withstand the thermal shock fluctuation caused by frequent start-stop.
Its heat transfer range is dozens of times of the light tube, can strengthen the heat transfer, reduce the flow resistance, the same heat exchange can greatly reduce the volume of the facility and reduce the alloy consumption, thus improving the economy and operational reliability of the heat exchange equipment.
The basic function of the high-frequency welded finned heater element is to improve the surface of the fin, increase the surface area of the fin, and improve the heat exchange efficiency of the heat exchanger. Through the trend effect and proximity effect of high frequency current, the steel strip is heated to a plastic or molten state in the process of winding welding, and is wound and welded under a certain pressure.
