Working principle, use and classification of electric heating plate
- Clicks: 1059 Release time: 2014/7/4
The electric heating plate is a kind of electric heating device, which uses a heating alloy wire as a heating material, a material such as a mica soft plate as an insulating material, and an outer layer covered with a heat conducting plate made of stainless steel or the like. The electric heating plate belongs to one of the common electric heating devices of Zui. For example, the electric hot water bottle is a typical example of an electric heating plate for application.
1, the principle of electric heating plate
The heating material of the electric heating plate is an electrothermal alloy wire, and its working principle is very simple, which is the basic electrothermal effect. When the electric heating plate is working, the current passes through the electrothermal alloy wire, and the electrothermal alloy wire generates heat, converts the electric energy into heat energy, and conducts it to the outer casing. The electric heating plate is designed with an insulating material to ensure that the electric current of the electrothermal alloy wire does not cause a safety hazard to the user.
2, the advantages of electric heating plate
The electric heating plates are mostly flat and thin plate-shaped designs, and the structure is simple and uniform, and is easy to install and use. The electric heating plate is made of stainless steel or ceramic as the outer casing, and the electric heating alloy wire is enclosed inside the electric heating plate, so it is closed heating, no open flame, no odor when heating, good safety, suitable for various work. surroundings.
3. Classification of electric heating plates
There are no clear classifications of electric heating plates. The common electric heating plates on the market include stainless steel electric heating plates, ceramic electric heating plates, silicon rubber electric heating plates, carbon crystal electric heating plates and carbon fiber electric heating plates. The main difference is that the outer casing materials are different. Or the inner layer of heating materials are different, such as stainless steel electric heating plate and ceramic electric heating plate are different from the outer casing material, and the other several are different heating materials.
4, the use of electric hot plate
The advantages of electric heating plates are numerous, so there are very common applications in production and life. From ordinary floor heating and electric hot water bottles to the experimental environment temperature maintenance in the laboratory, the use of electric heating plates is indispensable. At present, electric heating plates have been widely used in various fields such as industry, agriculture, civil, defense, science and technology, and medical and health.
