How Is The Air Heater Working Better?

Now with the gradual deepening of the winter, our technology is constantly developing. For the treatment of the cold winter, we mainly use air heaters. This kind of heater is safer and more environmentally friendly, and has been well received by users. How to work better, today we will learn more about:

The air heater mainly installs a primary coil with a larger number of turns and a secondary coil with a smaller number of turns on the same core. The ratio of the input to the output voltage is equal to the ratio of the turns of the coil while the energy remains the same. Therefore, the secondary coil generates a large current under low voltage conditions. For an induction heater, the bearing is a short-circuited, single-turn secondary coil that passes a large current at a lower AC voltage, thus generating a large amount of heat. The air heater itself and the yoke are kept at normal temperature. Since this heating method can induce current, the bearing will be magnetized. It is important to ensure that the bearing is demagnetized in the future so that it does not attract metal chips during operation.

Air heaters have an automatic degaussing function that uses metal to generate eddy currents in an alternating magnetic field to heat itself, and is usually used in metal heat treatment. The principle is that when a thicker metal is in an alternating magnetic field, current is generated due to electromagnetic induction. When a thicker metal produces an electric current, the current will form a spiral flow path inside the metal, so that the heat generated by the current flow is absorbed by the metal itself, which causes the metal to heat up quickly in the high temperature resistant stainless steel. The high-temperature resistance wire is evenly distributed in the tube, and the crystalline magnesium oxide powder having good thermal conductivity and insulation performance is densely filled in the void portion. This structure is advanced not only advanced, but also has high thermal efficiency and uniform heat generation. When a current flows through the high-temperature resistance wire, The generated heat is diffused to the surface of the metal tube by the crystalline magnesium oxide powder, and then transferred to the heated member or the air to achieve the purpose of heating.

The main working principle of the air heater is these. We must operate it correctly during the use process. Only in this way can we ensure better work, improve work efficiency and extend the service life.
