Main Classification Of Heater Mar 14, 2019

According to the heating method, it can be divided into three types: electromagnetic heating, infrared heating and resistance heating:

1. Electromagnetic heating, electromagnetic heating is to generate an alternating magnetic field through the components of the electronic circuit board. When the upper part is placed on the iron-containing container, the surface of the container has an alternating magnetic field and the alternating current is generated at the metal part of the bottom of the container (ie, Eddy current), the eddy current causes the iron atoms at the bottom of the container to move at high speed and irregularly, and the atoms collide with each other and friction to generate heat energy. Thereby the effect of heating the article.

2, infrared heating, infrared heat transfer form is radiation heat transfer, energy is transmitted by electromagnetic waves. When the far infrared ray is irradiated to the heated object, a part of the ray is reflected back and a part is penetrated. When the far-infrared wavelength emitted is the same as the absorption wavelength of the object to be heated, the heated object absorbs far-infrared rays. At this time, the molecules and atoms inside the object resonate, generating strong vibration and rotation, while vibration and rotation cause the temperature of the object to rise. High, reaching the purpose of heating.

3. Resistance heating, a heating method for heating a billet by using a current to discharge heat through an electric heater. Common resistance wire heating, ceramic heaters, and resistance ring heating, quartz tube heating, in principle, are resistance heating.
