The heating tube is a metal tube with a resistance wire inside, and the seamless metal tube (carbon steel tube, titanium tube, stainless steel tube, copper tube) is filled with electric heating wire, and the gap is filled with magnesium oxide powder with good thermal conductivity and insulation. Tubes, and then processed into various shapes required by users. It can be used to heat various liquids and acid-base salts, and it is also suitable for heating and melting metals with low melting points.
What is the working principle of the heating tube? Follow the editor of Xinhechang to understand:
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.
Heating pipe
Joule-Lenz Law: When an electric current flows through a resistor, the resistor will generate heat and convert electrical energy into heat energy. 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.
The heating tube is a metal tube with a resistance wire inside, which is the same as an electric stove 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.
