Far infrared heating plate

Basic Theory of Far Infrared Heat Transfer
1Far infrared heating plateThe infrared characteristics (wavelengths) emitted by objects with different characteristics are different, and infrared rays with different characteristics are easily received by objects with the same characteristics - that is, infrared rays emitted by solid materials are easily absorbed by solids and not easily absorbed by gases.
2. The forms of thermal energy transfer for far-infrared heaters are radiation, conduction, and convection.
3. The thermal energy of far-infrared heaters is mainly (90%) transferred in the form of radiation at high temperatures, and its radiation intensity is proportional to the fourth power of temperature.
4. The absorption capacity of far-infrared heater radiation heat energy is directly proportional to the surface blackness of the heated object.
5. The thermal conductivity of a far-infrared heater is directly proportional to the temperature gradient (on the surface and inside of the object) and inversely proportional to the thermal resistance.
Far infrared heating plateEnergy saving principle
After the electric heating coating is cured, a strong coating is formed. Due to its high surface blackness, the coating can absorb a large amount of radiation heat energy, and due to its high emissivity, it can convert the absorbed radiation heat energy into far-infrared heat energy that is easily absorbed by objects and transmit it in the form of electromagnetic waves The coating thickness, high thermal resistance, and high reflectivity of micrometer level electric heating coatings are used on the surface of oven plates to convert the dissipated heat energy into far-infrared heat energy and radiate it into electromagnetic waves inside the oven, which are absorbed by the heated objects inside the oven and are not easily absorbed by moisture, thus keeping the heat energy inside the oven. This not only reduces the moisture discharge temperature, but also raises the temperature inside the oven, making full use of the temperature inside the oven The coating of nanoscale electric heating coating is thin and has low thermal resistance. It is used on the surface of metal materials that are heated and thermally conductive in an oven. During the heat transfer process, the coating layer not only converts the absorbed radiation heat into far-infrared heat and transfers it, but also becomes a far-infrared radiation heat source. Moreover, due to the increase in surface temperature, the temperature gradient increases, which enhances the thermal conductivity of the heated object and greatly improves its heat absorption capacity In summary, the direct effect of converting radiant heat energy into far-infrared heat energy through electric heating coatings is to increase the temperature of the oven, reduce the temperature of moisture loss, and enhance the heat absorption rate of the heated object; Reducing heat loss and achieving energy-saving goals.
