Abstract
A vertically-oriented solar collecting apparatus primarily for installation in the wall of a building is disclosed in which the panel has a heat collecting plate spaced therefrom and covering an open cell formed in the panel which has lower and upper openings communicating therewith. The cell may be provided with deflecting devices to create turbulence within the cell and the panel has a cover thereover capable of passing the sun's heating rays and forming a heat trap.
Claims1
A hot air type solar heat-collecting apparatus comprising
- (a) an upwardly extending outer door panel fitted into a wall of a building within a frame with openings therethrough at different vertical levels, said panel being so oriented as to receive the rays of the sun,
- (b) a heat-collecting plate having a substantially black coating over its surface spaced from said panel and covering said openings and forming with said panel a closed heat chamber except for said openings,
- (c) a heat trap cover capable of passing sun's heating rays covering said plate whereby the sun's rays will pass through said cover and impinge upon said plate and heat air in said chamber.
