Features Of Far Infrared Heating Tube

In our daily life, the wavelength from 0.76 to 400 microns is called infrared, which is invisible light. All substances above absolute zero (-273℃) can produce infrared. Modern physics calls it heat rays.

Infrared can be divided into two types: near infrared and far infrared. Today we mainly talk about the characteristics of far infrared heating tubes.

The physical properties of far infrared heating tubes are:

1. There is a thermal effect

2. Strong ability to penetrate clouds and fog (longer wavelength, easy to diffract)

The main characteristics of far infrared electric heating tubes are:

1. Objects with different characteristics emit infrared characteristics (wavelengths) differently, 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, but not easily absorbed by gases.

2. Forms of heat transfer: radiation, conduction, and convection.

3. The heat energy of far infrared electric heaters is mainly (90%) transmitted 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 radiant heat energy is proportional to the surface blackness of the heated object.

5. When using far-infrared electric heaters, the heat energy conduction intensity of the heated object is proportional to the temperature gradient (on the surface and inside of the object) and inversely proportional to the thermal resistance.
