2. The typical structure of a low-voltage high-power single-head electric heating tube (the most popular structure) is the same as that of an electric heating tube. It is generally composed of insulators, sealing materials, Lead rod, filler, heating wire, metal sheath tube, terminal. The spiral heating wire and the lead-out are located in the center of the metal sheath tube. Its manufacturing process is to penetrate the spiral heating wire into the seamless steel pipe, copper pipe or aluminum pipe, and the gaps are evenly filled with a multi-tube filling machine, which is both insulating and Thermal conductive oxidation medium, such as crystalline magnesium oxide powder (alumina or clean quartz sand can also be used). Then use a tube shrinking machine to reduce the diameter of the tube to make the oxide medium dense (density reaches ./above) to ensure that the heating wire is isolated from the air and that the center position does not shift and hit the tube wall. so. The amount of heat generated per unit area can be increased more than ten times. The service life can also be correspondingly increased to more than 10 years. Compared with electric heating elements with the same large amount of heat, tubular electric heating tubes can save 50% of electric heating materials, and the thermal efficiency can reach more than 10%.
