parabolic trough concentrator for keeping the refraction rate and reducing the heat loss

摘要

PURPOSE: A heat collector capable of maintaining reflectance and reducing heat loss is provided to prevent the escape of heat from an absorbing device by placing the high-temperature absorbing device in a vacuum condition. CONSTITUTION: A heat collector comprises a reflector(100) and an absorbing device(200). The absorbing device is installed in a vacuum chamber(2) and absorbs the heat reflected off the reflector as heat. A transparent plate(1) is installed in front of the reflector and insulation flat panels on the sides in order to isolate the reflector from the exterior air and block foreign materials attached to the reflector surface.
