Language The heat transfer principle of nano infrared electric heating coil:
The nano-infrared heating coil itself becomes a far-infrared radiation heat source, and the temperature gradient increases due to the increase of its surface temperature, which enhances the heat transfer intensity of the heated object and greatly improves the heat absorption capacity. The direct effect of converting radiant heat energy into far-infrared heat energy through electrothermal paint is: increase the temperature of the heated object, reduce the temperature of moisture loss, enhance the heat absorption speed of the heated object, reduce the heat loss, and achieve energy saving the goal of.
1. Objects with different characteristics emit different infrared characteristics (ie, wavelengths). Infrared rays with different characteristics are easily received by objects with the same characteristics, that is, the infrared rays emitted by solid materials are easily absorbed by solids and not easily absorbed by gases.
2. Forms of heat transfer: radiation, conduction, and convection.
3. Heat energy is mainly (90%) transferred in the form of radiation at high temperature, and its radiation intensity is proportional to the fourth power of the temperature.
4. The absorption capacity of radiant heat energy is proportional to the surface blackness of the heated object.
5. The heat conduction intensity of the heated object is directly proportional to the temperature gradient (on the surface and inside of the object) and inversely proportional to the thermal resistance.
Energy-saving principle of nano infrared electric heating coil:
After curing, the nano-electric heating coating forms a strong coating. Because of its high surface blackness, the coating can absorb a large amount of radiant heat energy, and because of its high emissivity, it can convert the absorbed radiant heat energy into a long-distance that the object can easily absorb. Infrared heat energy is transmitted in the form of electromagnetic waves. The coating of micron-level electric heating paint has large thermal resistance and high reflectivity. It is used on the surface of the barrel to convert the lost heat energy into far-infrared heat in the form of electromagnetic waves. Moisture absorption, thereby leaving heat energy in the barrel, not only reduces the temperature of moisture discharge, but also increases the temperature in the barrel, so that the temperature in the barrel is fully utilized.
