commercial and household fields. They convert electrical energy into thermal energy to achieve various functions such as heating, insulation, and drying. This article will detail the working principle, classification, application fields, and usage precautions of electric heating equipment.
Working Principle
The basic working principle of electric heating equipment is to use resistance wires or other heating elements to convert electrical energy into thermal energy. When current passes through the resistance wire, according to Joule's Law, the resistance wire generates heat. This heat is transferred to the medium or object that needs to be heated through conduction, convection, or radiation.
