In all kinds of heating equipment, electromagnetic induction heating coils are used, which are also called electromagnetic heating controllers. Next, Kehua will take you to see what is an electromagnetic induction heating coil and what is its working principle? What is an electromagnetic induction heating coil? An electromagnetic induction heating coil is what we usually call an electromagnetic heating controller. The heating coil, as for whether it can save energy and how the energy saving effect is, is not only related to the quality of the electromagnetic induction heating controller itself, but also related to the heating equipment in different industries. Generally, the power saving effect can reach at least 30%, and the highest can reach more than 70%. The original heating ring: it heats the barrel through thermal conduction, radiation and convection, and the Joule heat generated by the resistance R (Joule heat is generated by the thermal vibration energy generated by the collision of atoms when electrons move in the resistance) → through insulation Material → to the heating ring housing → transfer heat to the barrel. After the electric energy is converted into heat, the heat energy that can be conducted and radiated to the barrel is less than 40%, resulting in a large amount of electric energy waste, and also deteriorating the environment of the workshop. Electromagnetic induction heating coil The working principle of the electromagnetic induction heating coil The electromagnetic induction heating coil rectifies, filters and inverts the 220V AC power supply into a high frequency alternating current of 25-30KHZ through power electronic technology and electromagnetic compatibility technology. A heating method in which the high-frequency alternating current is converted into a high-frequency alternating magnetic field, and the magnetic field is converted into a high-frequency alternating current when it hits the metal barrel, and this current causes the heated equipment to heat directly from the inside. Kehua believes that it fundamentally solves the problem of inefficiency of resistive heating through heat conduction, such as electric heating sheets and electric heating coils. Its heating efficiency is as high as 96%, which reduces the surface temperature of the barrel from hundreds of degrees to dozens of degrees. The electromagnetic induction heating coil is an indispensable accessory in the heating equipment. If the electromagnetic induction heating coil of good quality is used, a lot of energy consumption can be saved.
