More Information
Summary:Infrared radiating element made of vitreous silica comprises: (i) a heating pipe (2) having a gas-tight current leadthrough with an electrical heat conductor (4) arranged in the pipe as radiation source; (ii) a cooling element (3) having a cooling channel (3a) for liquid coolant in the region of the conductor; and (iii) a metallic reflector (8) with a reflecting surface. The reflecting surface inscribes a line around a surface through which a part of the liquid coolant can pass. Preferred Features: The reflector is made from a metal layer and the coolant channel of the cooling element is covered with the metal layer. The cooling element is a cooling tube surrounding a heating tube. The heat conductor is made of tungsten and the heating tube is filled with an inert gas doped with ammonium bromide or copper bromide.
