○Methods of Heat Transfer and Far Infrared Heating○~Trivia No. 4

Far infrared heating can supply a nearly constant heat flow into the interior of an object during the heating time.

One method of heat transfer, radiant heat transfer (far infrared heating), does not involve contact between the far infrared heater, which is the heat source, and the object. Therefore, even if the temperature of the object is set to a significantly higher level, the surface temperature of the object does not rise sharply. Organic materials, polymers, and ceramics that have absorbers at wavelengths of 3μ or more efficiently absorb heat on the surface through far infrared heating, which radiates at wavelengths of 3μ or more, allowing a nearly constant flow of heat into the interior of the object during the heating time. In other words, the entire object experiences a temperature increase. Since the thermal energy received at the surface flows almost entirely into the interior, the temperature rises almost linearly to the target temperature without just the surface temperature increasing. 【Trivia: Methods of Heat Transfer and Far Infrared Heating】 ○ Conduction → A method of heat transfer that involves direct contact between the heated object and the heat source. ○ Convection → A method that forces heated air or gas in contact with the heat source into the furnace to heat the object placed inside. ○ Radiation (Far Infrared Heating) For more details, please contact us or download the catalog.
