What is the working principle of an infrared radiator??

　   As electricity passes through an infrared radiator, it transfers heat to the surface of the heated material (workpiece) by convection through a medium (air), much like a standard electric heating element. On the other hand, the infrared radiator emits a large amount of infrared radiation of a specific wavelength. When this radiation is absorbed by the material, its internal molecules are activated and collide, generating a significant amount of heat energy, thereby heating the material from the inside. This method of heating objects by utilizing this characteristic is known as infrared radiation heating.

　　Due to the varying absorption capabilities of each material to infrared light of different wavelengths, to accommodate different materials, infrared radiators with various wavelengths can be produced by altering the winding method and material of the heating wire. Currently, commonly used infrared radiators primarily have wavelengths in0.78-1.4umLeft and right shortwave, wavelength1.4-1.8umLeft and right of the medium wave, wavelength1.8-2.2umLeft: carbon neutral wave and wavelength2.2-4.0umLeft and right medium wave.

Due to the low thermal inertia of infrared radiation but high thermal efficiency, shortwave and midwave infrared radiation technology can be utilized to heat workpieces with high density, energy, and intensity. This improves heating quality, shortens heating time, reduces energy consumption, saves production costs, and minimizes environmental pollution.
