Electric Cartridge Tubular Heaters

The typical structure (the most popular structure) of an electric cartridge tubular heater is the same as that of an electric heating tube. It is generally composed of 5 parts: insulator, sealing material, lead rod, filler, heating wire, metal sheath, and terminal. The spiral heating wire and the lead-out help are located in the center of the metal sheath. Its manufacturing process is to penetrate the spiral heating wire into seamless steel pipe, copper pipe or aluminum pipe. The gap is evenly filled by a multiple-tube filling machine. Thermally conductive oxidizing 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 compact (density above 3.3g/cm3), to ensure that the heating wire is isolated from the air, and the center position does not shift and touch the tube wall. such. The heat per unit area can be increased more than ten times. The service life can be correspondingly increased to more than 10 years. Compared with the electric heating element with the same large heat, the tubular electric heating tube can save 5% of the electric heating material, and the thermal efficiency can reach more than 90%.
