Abstract:
An infrared emitter comprising;a longitudinally extending energy emitting filament; a longitudinally extending, tubular enclosure formed of infrared energy transmitting material, the enclosure enclosing the filament, the enclosure having at least one inner tubular support device in a predetermined position, the inner tubular support device having a plurality of apertures operable to allow fluid flow through the inner tubular support device; a longitudinally extending outer tubular sheath formed of infrared energy transmitting material, the outer tubular sheath having an inner and an outer surface and a plurality of ports at predetermined locations to allow fluid flow through the sheath; a pair of end caps closing open ends of the outer sheath, each end cap having at least one passage operable to allow fluid flow therethrough; a reflector formed on a surface of the sheath and extending partially circumferentially around the sheath to define a window through which Infrared energy may pass; and wherein the sheath is spaced apart from the enclosure to protect the reflector from the infrared energy being emitted by the filament.
