Energy-saving principle of infrared heater Far infrared heater Basic theory of heat transfer: 1. The infrared characteristics (wavelength) emitted by objects with different characteristics are different, and infrared rays with different characteristics are easy to be received by objects with the same characteristics - that is, the infrared rays emitted by solid substances are easily absorbed by solids and not easily absorbed by gases. 2. Forms of heat energy transfer: radiation, conduction, convection. 3. Heat energy is mainly (90%) transmitted in the form of radiation at high temperature, and its radiation intensity is proportional to the fourth power of temperature. 4. The absorption capacity of radiated heat energy is proportional to the surface blackness of the heated object. 5. The thermal energy conduction intensity of the heated object is proportional to the temperature gradient (on the surface and inside the object) and inversely proportional to the thermal resistance. Energy-saving principle of electrothermal coating: After curing, a firm coating is formed, which can absorb a large amount of radiant heat energy because of its high surface blackness, and because of its high emissivity, it can convert the absorbed radiant heat energy into far-infrared heat energy that is easily absorbed by the object and transmitted in the form of electromagnetic waves. Micron-level electrothermal coating has thick coating, large thermal resistance and high reflectivity, which is used on the surface of the oven plate to convert the lost heat energy into far-infrared heat energy in the form of electromagnetic waves radiating into the oven, which is absorbed by the heated object in the oven, and is not easy to be absorbed by moisture, so as to leave the heat energy in the oven, which not only reduces the moisture discharge temperature, but also increases the temperature in the oven, so that the temperature in the oven is fully utilized. The coating of nano-scale electrothermal coating is thin, the thermal resistance is small, used for the surface of the metal material in the oven that is heated and conducted, in the heat transfer process, the coating layer not only converts the absorbed radiant heat energy into far-infrared heat energy transfer, which itself becomes a far-infrared radiant heat source, but also because of the increase of its surface temperature, resulting in an increase in temperature gradient, so that the heat energy conduction strength of the heated object is enhanced, and the heat absorption capacity is greatly improved. In short, the direct effect of converting radiation heat energy into far-infrared heat energy through electrothermal coating is: to increase the temperature of the oven, reduce the temperature of moisture loss, and enhance the heat energy absorption rate of the heated object; Heat energy loss is reduced and energy saving is achieved. Infrared noun explanation: Infrared is one of the many invisible rays of the sun, discovered by British scientist Hosch in 1800, also known as infrared thermal radiation, he broke up sunlight with a prism, placed thermometers on various color ribbon positions, trying to measure the heating effect of various colors of light. It was found that the thermometer located on the outside of the red light warmed up the fastest. Therefore, it is concluded that in the solar spectrum, there must be invisible light on the outside of red light, which is infrared. It can also be used as a medium for transmission. The wavelength of infrared rays on the solar spectrum is greater than that of visible rays, with a wavelength of 0.75~1000μm. Infrared can be divided into three parts, namely near-infrared, with a wavelength between 0.75~1.50μm; mid-infrared, with a wavelength between 1.50~6.0μm; and far-infrared, with a wavelength between 6.0~l000μm. Physical properties of infrared: A segment of the spectrum with wavelengths from 0.76 to 400 microns is called infrared, and infrared is invisible light. All substances above absolute zero (-273°C) can produce infrared light. Modern physics calls this heat rays. Medical infrared can be divided into two categories: near-infrared and far-infrared. Near-infrared or short-wave infrared, wavelength 0.76~1.5 microns, penetrating deep into human tissue, about 5~10 mm; Far infrared or long-wave infrared, wavelength 1.5~400 microns, mostly absorbed by the surface skin, penetrating tissue depth less than 2 mm. ...............
