electrical heaters is the use of power to achieve the heating effect of electrical appliances

electrical heaters is the use of power to achieve the heating effect of electrical appliances, according to the type of heating method to distinguish, they can be divided into three categories:
1. electromagnetic heating - electromagnetic heating is part of an alternating magnetic field at the bottom of the metal part of the container alternating current through the electronic circuit boards, when used with iron container is placed above the surface of the container that is cut with an alternating magnetic field lines ( That vortex), eddy current so that the bottom of the container-speed random motion of the iron atoms, atoms collide with each other, friction generated heat. Heating effect and thus play items. Because self-heating container is made of iron, all thermal conversion rates are particularly high, up to 95%. Induction cookers are based on electromagnetic heating technology.
2. The infrared heating, heat transfer in the form of ceramic infrared heaters-- infrared radiation heat transfer, transfer energy from the electromagnetic wave. When far-infrared radiation to an object to be heated, a part of rays is reflected back, partially penetrated past. When the far-infrared wavelengths emitted by heated objects and consistent absorption wavelength, the heated object absorbs far infrared rays, this time, the internal molecular and atomic objects happen "resonance" - a strong vibration, rotation, and vibration and rotation of the body temperature rises, reaching the purpose of heating.
3. The resistive heating, electric panel heaters-- use electric current through the body to release heat the heating method blank. Common heat resistance wire, ceramic heaters, as well as resistance heating coil, quartz tube heating, the principle belong to resistive heating.
