Abstract

PURPOSE:To prevent the selective adsorbing surface of a heat collecting plate from deterioration resulting from the surface being overheated by the radiant heat of the sun by a method wherein in the titled heat collector in which a heat collecting body is sealed in a vaccum glass tube, a reflecting plate is arranged between a part of the glass tube to be heated at the time of vacuum sealing and the heat collecting body. CONSTITUTION:The heat collecting body comprising a heat collecting plate 2 and a heat collecting pipe 3 is sealed in the vacuum glass tube 1. In this case, the reflecting plate 6 in the form of a plain aluminum disk is provided between the heat collecting plate 2 and a vacuum sealing end 5 of the glass tube 1 so that the selective adsorbing surface of the heat collecting plate 2 is protected against the radiant heat of the sun at the time of vacuum sealing the heat collecting body in the glass tube 1 and as a secondary effect, sunlight reflects on the reflecting plate 6 to become incident on the heat collecting plate 2 to thereby increase the heat collecting efficiency of the plate 2. Further, a second reflecting plate 7 is provided on the front surface of a header 4 so that sunlight reflects on the reflecting plate 7 to become incident on the heat collecting plate 6 to thereby increase the heat collecting efficiency of the plate 6, too.
