<p>PURPOSE:To provide the infrared rays rediating body radiating enormous amount of infrared rays in liquid by a method wherein the ceramics of metal oxide, radiating infrared rays, is coated on the surface of an exothermal body consisting of silicon carbide. CONSTITUTION:The surface temperature of the silicon carbide exothermal body 7 is set at 1,000 deg.C and the electroconductive section 8 of the same is im pregnated with a metal. The ceramics of metal oxide, having a high infrared rays radiating efficiency, is coated on the surface of the same while the surface is coated with the thin film of silicon carbide to provide the surface with an electric insulating property. Terminals are attached to both ends of the electroconductive section 8 and lead wires 10 are connected to the terminals. The fittings 11 of metallic thin tube, having a bellows 9, is provided near the exothermal body 7 and the electroconductive section 8 and both end faces there of are formed with indentations vacuum of filled with inert gas such as argon or the like. The radiation coefficient of the metal oxide ceramics is about 90%, therefore, 10% of energy, thrown thereinto, is accumulated in the radiating body and the temperature thereof becomes higher than the set temperature.</p> |
