Wedge-shaped solar air heating device

Claim 1

A solar heating device adapted to be mounted against the exterior of a building and having rearwardly extending ducts for insertion into a building through an opening to the interior of the building, which comprises means defining a wedge-shaped casing having a heat pervious front wall inclined toward the building at an angle providing incidence to the sun and providing a wedge-shaped configuration with the tapered end being uppermost, two parallel essentially triangular side walls, bottom and top walls, and a rear wall, said casing having internally thereof a divider panel parallel and coextensive with the inclined front wall but for the lower end of the panel which terminates spacedly above the bottom, thus forming a passage from resultant front and rear chambers, said casing having first duct-forming means extending rearwardly from the upper portion of the rear wall and communicating with said rear chamber, and second duct-forming means extending rearwardly from the upper portion of the rear wall and communicating with said front chamber, said first and second duct-forming means constituting a casing support extension being located in relatively remote, elevated relationship to the lower portion of said casing rear wall, there being an air inlet at the end of said first duct-forming means remote from the communication thereof with said rear chamber, there being an air outlet in the portion of said second duct-forming means remote from the communication thereof with said front chamber, and heat transfer means disposed within said front chamber and comprising a heat-impervious rounded corrugated sheet overlying the forwardly-presented surface of the divider panel and having evenly-spaced longitudinal, alternating half round countours, and on the face of said corrugated sheet a superimposed heat impervious fine mesh metal screen, and said front wall comprising a heat-pervious double-glazed pane with predetermined spacing between glazings, and wherein downwardly diverging baffles are disposed across the rear cool air chamber from back to front.
