When the application of rated voltage on the electrode of the heating body on both ends, and under the action of electromagnetic field, the current through the conductor heating element and semiconductor, form the current loop. At the same time, electric ion in heat friction and resistance heatingbody collision, namely a heat energy. In the decades after the power supply in seconds, heating surface average temperature from the temperature of the environment, is rapidly increased, and the heat transfer to cover in the heating body on the surface of the silicon infrared radiation coatings andinsulation materials on the back of the heating body. The heat insula. The heat insulation material continuously reflected to the surface temperature of the heating body, a heating body and a silicon infrared radiant coatingincreases. Radiation particle coating silicon crystal absorption of electromagnetic energy in the heating body came, and polarization occursin the oscillation under the action of magnetic field, which induces amagnetic multipole oscillation. The and electromagnetic oscillation,far infrared emission of electromagnetic waves in all directions, the formation process of particle scattering of electromagnetic radiation, i.e.. In3-5 minutes, between the infrared radiation material coating, a heating element and a heat insulation body reached the dynamic thermal balance,far infrared silicon hot shot board heat radiation with constant temperature.
The theory of heat radiation
We can take the heat radiation are summarized in the following two kind ofdefinition:
A, generated by the thermal motion, transfer in the form of electromagnetic wave energy, thermal radiation is the process of energy transfer.
Two, by thermal reasons, objects in the form of a photon energy transfer,heat radiation is the process of energy transfer. The electromagnetic wavegenerated by the thermal motion is called heat ray, wavelength is defined asin the 3-1000 micron far infrared ray. Usually applied with thermal radiationheating far infrared wavelength human for 8 to 13 micron. In this band, the heat ray radiation of heat generated, and no harm to the human body, the human body because of the natural radiation wavelengths is precisely inthis band. Medical infrared spectrum instrument is the use of this principle,physical therapy for 8 to 13 of the human body infrared radiation wave. So,a far infrared heater design reasonable, it not only can be used for heating,can also carry out.
Infrared radiation heating is nothing new, all hot objects directly or indirectlyemits infrared electromagnetic wave, such as the sun, the earth, the human body. From a scientific definition, to the object's temperature above absolute zero or more than 273 degrees below zero, the object will continue to convert heat energy into radiant energy, outgoing heat rays; at the same time, the object is also constantly absorbing the heat ray projection over thesurrounding objects, and put energy into heat energy absorption of radiation.
