Nano infrared heating circle heat transfer principle:

Nano infrared heating circle itself into a far infrared radiation heat source, but also because of its surface temperature increases, resulting in increased temperature gradient, so that the heated objects to enhance the thermal conductivity, endothermic capacity greatly improved. The direct effect of converting radiant heat into far-infrared heat by electrothermal coating is to increase the temperature of the object to be heated, reduce the temperature of the heat rejection, enhance the heat absorption rate of the heated object, reduce the heat loss, the goal of.

1. Infrared characteristics (ie, wavelengths) of different objects are different. Infrared rays of different characteristics are easily accepted by objects with the same characteristics. Infrared rays emitted by solid matter are easily absorbed by the solid and are not easily absorbed by the gas.

2. The form of heat transfer: radiation, conduction, convection.

3. Thermal energy at high temperature (90%) in the form of radiation, the radiation intensity and the temperature is proportional to the fourth power.

4. The absorption capacity of radiant heat is proportional to the surface blackness of the heated

object.

5. The thermal energy of the heated object is proportional to the temperature gradient of the surface and the inside of the object and is inversely proportional to the thermal resistance

Nano-infrared heating circle of energy-saving principle:

Nano-electric coating after curing to form a solid coating, the coating because of its high surface blackness, it can absorb a lot of radiant heat, and because of its high emissivity, it can absorb the radiation heat energy into the object easily absorbed far Infrared heat, and in the form of electromagnetic waves. The coating of the micro-scale electrothermal coating has high thermal resistance and high reflectivity for the surface of the barrel. The heat energy is converted into far-infrared heat in the form of electromagnetic waves, which is absorbed by the barrel and is not easily Moisture absorption, which will heat left in the barrel, not only reduces the temperature of the row of trenches, but also the barrel of the temperature rise, so that the barrel of the temperature has been fully utilized. In the heat transfer process, the coating layer not only absorbs the radiant heat energy into far-infrared heat transfer, the far-infrared heater itself becomes a far-infrared radiation heat source, but also because of its surface temperature increase, resulting in increased temperature gradient The thermal conductivity of the heated object is enhanced and the endothermic capacity is greatly improved. In short, the direct effect of converting radiant heat into far-infrared thermal energy by electrothermal coating is to increase the temperature of the barrel, reduce the temperature of the heat rejection, enhance the heat absorption rate of the heated object, and reduce the heat loss The purpose of energy conservation.

Far infrared features:

1, the emissivity: because the far infrared is part of the ray of electromagnetic waves, so it does not need any light with the media can be directly conduction, which is far infrared emission.
