electric heating

Tubular electric heating tubes are heating elements that convert electrical energy into thermal energy. It has a stainless steel shell, crystalline fused magnesia sand as the insulator, and an internal heating wire for heat generation. The working principle is as follows: After the electric heating wire is electrified, it generates heat energy, which is then insulated by electrically fused magnesia sand and conducted to the all-metal casing. Finally, the heat energy is released and absorbed by the heating medium. The surface temperature of the heat pipe is generally controlled below 500℃. To increase the heat dissipation area of metal tubular electric heating elements, thereby enhancing the unit power and extending the service life, some heating tubes have specially designed heat dissipation fins on their surfaces. The surface load can be designed to be 3-5W/c㎡. Electric heating tubes can be used in the following industries. Heating of household appliances such as air conditioners, washing machines and water heaters.
