The temperature of the air electric heater manufacturer can be heated up to 850 ℃

As the name suggests, the air heater manufacturer is a device for heating air. Widely used in aerospace, chemical plants, and university research laboratories. The air it produces is dry, non-conductive, non combustible, and pollution-free. Its efficiency is also relatively high, reaching 90%. Do you know how it works? Next, I will share with you how the air electric heater manufacturer works.

Install primary coils with more turns and secondary coils with fewer turns on the same iron core. The input-output voltage ratio is equal to the coil turns ratio, while the energy remains constant. Therefore, the secondary coil generates a large current at low voltage. For induction heaters, the bearing is a short circuited single turn secondary coil that generates a large amount of heat under low AC voltage conditions through a large current.

The heater itself and yoke are kept at room temperature. Due to the induction of current by this heating method, the bearings will be magnetized. It is important to ensure that the bearings will demagnetize in the future so that they will not absorb metal magnetic debris during operation. The Fag induction heater has an automatic demagnetization function. It uses eddy currents generated in a metal alternating magnetic field to heat itself. It is usually used for metal heat treatment.

The principle is that when thicker metals are in an alternating magnetic field, they will generate current due to electromagnetic induction. When thicker metal generates current, the current forms a spiral flow path inside the metal. In this way, the heat generated by the current will be absorbed by the metal itself, leading to a rapid increase in metal temperature.

The high-temperature resistance wire is uniformly distributed inside the high-temperature stainless steel seamless pipe, and the gaps are filled with dense crystalline magnesium oxide powder, which has good thermal conductivity and insulation properties. This structure is not only advanced, with high thermal efficiency, but also uniformly heated. When there is current passing through the high-temperature resistance wire, the heat generated diffuses to the surface of the metal tube through crystalline magnesium oxide powder, and then transfers to the heated component or air to achieve the purpose of heating. Electric air heaters are mainly used to heat the required airflow from the initial temperature to the desired air temperature, with a maximum temperature of 850 ℃.
