Information

Under the sunlight, the sunshine side is warming but the sunless side is cold. This is not due to temperature differences, but the radiative heating energy of electromagnetic waves (infrared radiation) from the sun that is transferred to objects, so the sun is the source of heating energy.

We encapsulate the high-temperature heating filaments (up to 2600°C) into quartz tube as an energy source of heating (quartz infrared heating lamp), when our quartz infrared lamp is power on, which radiates near-infrared, middle-infrared and far-infrared like sun.

1. Fast Heating, the energy of infrared light is directly absorbed by material molecules, and the energy density of infrared light is very large, the surface temperature of the heated materials will increase quickly. This infrared heating speed is much higher and efficient than the speed of conduction and convection. The latter requires molecular collisions, which are transferred step by step through the conversion of kinetic and potential energy.

2. The infrared heating is more surface heating. As mentioned above, medium wave infrared heater tube heats the surface of an object very rapidly, so there is a large temperature difference between the surface and the interior of the object. This is a great advantage for the purpose of rapidly heating the surface of an object, as this does not cause large changes in the bulk temperature of the material. Energy saving without having a big impact on the humidity, chemical properties, stress, etc. of the object. But it also has the disadvantage, that is uneven heating for objects with irregular shapes, the disadvantage will cause temperature differences. At this time, we can have hot air in to get a uniform heating with infrared heater tubes.

3. Infrared heating has certain penetrability. The wavelength of shortwave infrared heater tube can penetrate the surface of an object to a certain depth, and when the molecules within this depth absorb the shortwave infrared, they heat from the inside to the outside at the same time. This has great advantages over conduction and convection, not only fast heating, but also to a large extent avoids the phenomenon of surface sealing and blistering.
