The heating wire is the most common type of heating element, and its function is to generate heat after being energized, and convert electrical energy into heat energy. The application range of electric heating wire is very wide. Many common electric heating equipments use electric heating wire as heating element. Therefore, electric heating wire has applications in medical, chemical, electronics, electrical, metallurgical machinery, ceramic glass processing and other industries.
1, the working principle of electric heating wire
The working principle of the heating wire is the same as that of other metal heating elements, and it is the electric heating phenomenon after the metal is energized. Electrothermal means that after the current passes through the conductor, the current generates a certain amount of heat and is transmitted by the conductor. The heating wire itself is a metal conductor that emits heat and provides thermal energy when energized.
2, the type of electric heating wire
The type of electric heating wire is divided according to the chemical element content and the structure of the heating wire. The types of electric heating wire are iron-chromium-aluminum alloy electric heating wire and nickel-chromium alloy electric heating wire. These two kinds of heating wire are used as electric heating elements in functional characteristics. The aspects are different.
In short, the purchase of electric heating tubes, such as stainless steel electric heating tubes, single-hair heat pipes, ceramic electric heating tubes, quartz heating tubes or other such as carbon fiber heating tubes, electric heating coils, heating plates, etc., must be combined with electric heating tubes according to the specific use environment. Comprehensive consideration of price, quality, use, etc., to avoid some misunderstandings when purchasing electric heating pipes.
