infrared heater
infrared heater radiation It is an electromagnetic wave that has a longer wavelength than visible light. It is in the range of 0.76 μm-1000 μm. The wavelength in this range is further subdivided according to Table 1, but in industry it is used in the range from short wavelengths to about 25 μm.

infrared heater Infrared infrared radiation almost does not cause a reaction. Photochemistry when absorbed by an object But almost all of the radiation energy becomes heat. Therefore, in terms of heat transfer, it is considered as a radiant heat phenomenon. infrared heater
heating with infrared rays infrared heater infrared
infrared heater It takes advantage of the heat generated by the absorption of energy (Dielectric Absorption) of electromagnetic waves in the infrared range that strikes dielectric objects. There will be energy absorption in resonance between the frequencies of The incident wave strikes the unique oscillations of the atoms that make up the body, so each body has its own absorption spectra per frequency. (wavelength)
because infrared radiation The infrared heater has a high optical frequency range. Most of the energy of the incident wave is absorbed by the surface layer. and rapidly decreased as the depth of the object sank. This tendency is more pronounced in the case of near-infrared radiation, which has a short wavelength. and the energy density will also increase. infrared heater
Infrared heater, high frequency infrared heater, from the description above. The properties of heating can also be summarized. infrared rays have the following infrared heater
1) Infrared heater Thermal energy is transferred directly to the object by radiation without the use of a heat transfer medium. therefore has low heat loss and can heat up quickly. On the other hand, it has a weak point that makes it difficult to heat the shiny part of the object. infrared heater
2) infrared heater, the heat capacity of the radiation source and heating device is small, and It is radiant heat, so it has a good temperature control response. It can control the temperature conveniently. suitable for automatic control infrared heater
3) Infrared heater infrared rays It has a high optical frequency range, so it is suitable for surface heating of dielectric materials. infrared heater
4) Infrared heater various objects In order to be effective, it is important to select a source of radiation that matches the characteristics of the object to be effective.
source of infrared radiation infrared heater The most commonly used are infrared ray tube Infrared heater and quartz tube heater, infrared ray tube The color temperature of the filament is about 2000-2500K, which is lower. lamps for general lighting The wavelength range of the emitted radiation is about 0.8-2.5 μm, so it is used as a source. Near-infrared radiation heaters are mainly near-infrared radiation heaters (Fig. 1). In general, glass and quartz do not allow waves with a wavelength of 4 μm or more to penetrate. Therefore, when longer wavelengths are needed, heating elements such as nichrome or tantalum are used in the condition. bare In this case, the color temperature is about 700-1000K, the wavelength range is about 2-10 μm.

Description infrared heater
Infrared Heater Infrared Heater Feature Available in both white (quartz glass) and black (ceramic) tubes, can be installed vertically and horizontally, small size, heat without flames high security The electrodes can be ceramic. or stainless steel The growth of the tube is standard at 10,14,18,20 millimeters, the length of the general tube should not exceed 2,500 millimeters.
Features of infrared heaters
It is an infrared heater. Infrared Heater characteristics working with radiant heat electromagnetic waves cause the workpiece to cause the molecules to vibrate Works very well for objects with relatively large molecular sizes. There are both long, medium and short frequency waves that can heat the workpiece with thickness. But it should not have a luster. Can save up to 30% on electricity bills compared to other heaters. and will save on electricity bills Add more when used in conjunction with an infrared reflector. infrared heater
Infrared heaters infrared heaters transmit radiant heat (as the sun sends heat to the earth), so they are highly efficient. Low loss, saving 30-50% of electricity
- infrared heater Able to heat objects up to the inside thus saving time 1-10 times (convection heating And the heat conduction will cause the object to heat only at the surface and then gradually penetrate into the inside, so it takes a lot of time.
- infrared heater It is smaller than conventional heaters, thus saving space.
- Infrared heater, installation and removal for easy maintenance.
- infrared heater high security because there is no flame The housing is highly insulated, no light leakage.
- Infrared heater gives radiation in the range 3-10 µm., which is the range that almost all materials can absorb radiation.
