At present, electric heating devices for general industrial use are composed of electric heating wires (including infrared type, quartz tube type, ceramic tile type, etc.), and its technology is nothing more than coating other materials on the heating wire, such as ceramics, quartz, glass, etc. etc. as a protective layer. Its mechanism is to convert electrical energy into light energy and then into heat energy. This electric heating device has at least the following deficiencies:

First, the electrothermal conversion efficiency is lower than 90%.

Second, the heating wire or heating body radiates heat to the surroundings (360 degrees), and a considerable part of the heat is consumed in other places that do not need heating, resulting in heat loss and low effective utilization of heat. the

Third, in order to increase the heating temperature, some products unilaterally adopt the scheme of increasing power, which makes the product waste more energy, cause more pollution, and shorten the life span, resulting in high energy consumption and high pollution (referring to heat dissipation of the surrounding environment, improving ambient temperature), a vicious cycle of high costs. the
