Infrared radiator has a cryptocrystalline carbon radiation element to increase the service life of the element at high temperatures, due to the lack of hot spots

摘要

Infrared radiator has a housing with a carbon radiation source. The housing has at least a window or hollow tube that is transparent to IR radiation, while the electric contacts are provided to connect the carbon radiation source (2) to a power supply. The carbon itself is of cryptocrystalline form. An independent claim is made for a radiation source of cryptocrystalline carbon with a specific power in the range 150 to 250 W/cm.
