Abstract
A solar heat collector, suitable for installation in inclined position to face the sun, as on a sloped roof, includes at least one flexible, usually substantially flat, wall member and a conforming second wall member, preferably with both wall members being of thin conductive metal, such as used aluminum printing plates, with both walls being spaced part to form passageways for the flow therethrough of a heat transfer fluid under a vacuum so that the walls are pressed toward each other. To allow flow of heat transfer fluid through the solar heat collector panel without obstruction because of the vacuum one or both walls may be formed into channel shapes or the collector may include a spacing and/or rigidifying screen or equivalent between the walls, highly preferably with the panels being indented or shaped to conform with openings in the screen, thereby helping to position the screen and to improve heat transfer. The wall members usually communicate with a plurality of manifolds to facilitate circulation of the heat transfer fluid through the solar heat collector. The external face of the wall facing the sun may be black, or such wall may be transparent and the interior of the other wall may be black; alternatively, the first wall may be transparent (or less desirably, translucent) and the heat transfer fluid may be dark colored, preferably black, to promote heat absorption. Also described are solar heating installations including pumps for circulating a heat transfer fluid through the collector and means, which may include, in part at least, the mentioned pumps, for drawing a vacuum in the interior of the collector. The use of vacuum, in conjunction with channels in the collector walls or screening or other spacing and shaping material between the walls which wall surfaces may conform to openings in such screening or other such material, promotes better thermal contacts so as to improve efficiency of the solar heat collector and the heating installation and also helps to rigidify the collector.
