Electric heater, its function is to heat, and it is also a kind of heating device or equipment that is used more. The heating methods of electric heaters mainly include the following:
1. Resistance Heating
It is to use the Joule effect of current to convert electrical energy into heat energy, so that it can heat objects. It can be divided into two types: direct and indirect. The former belongs to internal heating, so its thermal efficiency is high, and the operation is simple and convenient. The latter requires a small resistivity and temperature coefficient of resistance, so it is necessary to use a voltage regulator during use, which can generally be used in some special occasions.
2. Induction Heating
It is to use the thermal effect formed by the induced current generated by the conductor, so that the conductor itself heats up. There are three types of power frequency, intermediate frequency and high frequency.
Induction heating can not only heat the object uniformly as a whole, as well as the surface layer, but also perform arbitrary local heating, so it is still used a lot.
3. Medium Heating
It is to use high-frequency electric field to heat insulating materials, so its heating object is mainly dielectric. In industry, it can heat gels, paper, wood, etc., as well as plastics. For some homogeneous materials, bulk heating can be performed.
