How the heating tube works

Home    更新    How the heating tube works

The heating tube is a metal tube with a resistance wire, which is the same as an electric furnace wire. The heating principle is that the current passes through the resistor to generate heat. It has excellent performance such as long service life, high electrothermal conversion efficiency, far-infrared radiation, health and environmental protection.

 

According to the law of electric heating: the calorific value is proportional to the product of the square of the current and the resistance. The principle of current thermal effect: electrons are accelerated in an electric field, gain kinetic energy, have speed, and then collide with other particles (atoms, molecules, atomic groups) to make other particles gain kinetic energy, resulting in an increase in average kinetic energy and an increase in temperature. The principle of heating tube operation Joule-Lenz law: When current passes through a resistor, the resistor will generate heat and convert electrical energy into heat. This phenomenon is called the thermal effect of current.

 

Joule and Lenz through a large number of experiments, found that the heat generated by the resistance through the current is proportional to the square of the current, resistance and energization time. This is the Joule-Lenz law.
