Working principle of liquid heater
Jun 26, 2017

The principle of work is to put a more than primary and a few turns secondary on the same iron core. The input and output voltage ratio equals the ratio of coil turns, while the energy remains unchanged. Therefore, the secondary produces a large current under low voltage conditions. For induction heaters, the bearing is a short circuit secondary, with a lower AC voltage under the condition of a large current, resulting in a large amount of heat. The heater itself and the magnetic yoke remain at room temperature. Because the heating method can induce the current, the bearing will be magnetized. It is important to ensure that the bearing is degaussing in the future so that it does not absorb metal particles during operation. The heat-sensitive heater has automatic degaussing function.

It is the use of metal in alternating magnetic field to generate eddy currents and heat itself, usually used in metal heat treatment and so on. The principle is that the thicker metal in the alternating magnetic field, will be due to electromagnetic induction phenomenon and generate electricity. When the thicker metal generates current, the current will form a spiral-shaped flow within the metal, so that the heat generated by the current flow is absorbed by the metal itself, causing the metal to heat up quickly.
