Heating Coil and Heating Plate Parameters
[Physical Properties of Infrared]
1. In the spectrum, the wavelength range from 0.76 to 400 micrometers is called infrared, which is invisible light. All substances above absolute zero (-273°C) can produce infrared. Modern physics refers to it as thermal radiation.
2. Infrared can be divided into two categories: near-infrared and far-infrared. Near-infrared, or short-wave infrared, with wavelengths of 0.76 to 1.5 micrometers, penetrates deeper into human tissue, about 5 to 10 millimeters; far-infrared, or long-wave infrared, with wavelengths of 1.5 to 400 micrometers, is mostly absorbed by the surface skin, penetrating less than 2 millimeters into tissue.

1. Has thermal effect
2. Strong ability to penetrate clouds and fog (long wavelength, easy to diffract)
PSHJR Far-Infrared Heating Plate Basic Theory of Heat Transfer of Infrared
1. Objects with different characteristics emit infrared with different characteristics (wavelengths), and infrared with different characteristics is easily received by objects with the same characteristics - that is, infrared emitted by solid substances is easily absorbed by solids, not easily absorbed by gases.
2. Forms of heat transfer: radiation, conduction, convection.
3. At high temperatures, heat is mainly (90%) transferred in the form of radiation, and its radiation intensity is proportional to the fourth power of temperature.
4. The absorption capacity of radiant heat is proportional to the surface blackness of the heated object.
5. The heat conduction intensity of a heated object is proportional to the temperature gradient (between the surface and interior of the object) and inversely proportional to the thermal resistance.
PSHJR Far-Infrared Heating Plate Energy Saving Principle
1. The energy saving of the far-infrared heating plate is achieved by forming a cured coating of electric heating paint (imported product) on the radiation surface of the heater. Due to its high surface blackness, this 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 far-infrared heat energy that is easily absorbed by objects, transmitting it in the form of electromagnetic waves. The micron-level electric heating paint coating is thick, has high thermal resistance, and high reflectivity. When applied to the surface of an oven panel, it converts lost heat energy into far-infrared heat energy, radiating it inside the oven in the form of electromagnetic waves, which is absorbed by the heated objects inside the oven and not easily absorbed by moisture. Thus, the heat energy is retained inside the oven, not only reducing the exhaust temperature but also increasing the temperature inside the oven, making full use of the heat energy. The nano-level electric heating paint coating is thin and has low thermal resistance. When applied to the surface of metal materials that conduct heat in the oven, during the heat transfer process, this coating not only converts absorbed radiant heat energy into far-infrared heat energy for transmission, becoming a far-infrared radiation heat source itself, but also, due to the increase in its surface temperature, leads to an increase in the temperature gradient, enhancing the heat conduction intensity of the heated object and greatly improving its heat absorption capacity. In summary, the direct effect of converting radiant heat energy into far-infrared heat energy through electric heating paint is: increasing the oven temperature, reducing the temperature loss from exhaust, enhancing the heat absorption speed of the heated object, and reducing heat energy loss, achieving the goal of energy saving.
