Abstract
A radiant heating arrangement with a high infrared heating capacity for treatment chambers provides a vacuum-compatible radiant heating system with which it is possible to achieve considerable radiation levels reliably. The radiant heating arrangement includes a tube that is permeable to infrared radiation. The tube extends into the treatment chamber and penetrates the wall of the chamber with at least one end. A source of infrared radiation is situated inside the tube with the inside of the tube being isolated from the atmosphere inside the treatment chamber.
Claims4
A radiant heating arrangement for a vacuum chamber having walls enclosing a chamber interior space to be heated, comprising a quartz glass tube transmissive to infrared radiation, said tube passing through a sealed opening in at least one of said chamber walls and having an interior portion within said chamber and at least one exterior opening through which cooling air can be supplied to the interior of said quartz glass tube, an infrared radiation source located within said interior portion of said tube, and a reflector located within said interior portion of said tube for directing said infrared radiation within said chamber toward objects to be heated.
