Modular construction for solar heat collector

Claim 1

Modular construction for solar heat collectors using air transfer medium and arranged for connection to similar units comprising: a. a generally rectangular modular housing member including thin side walls and a bottom arranged to be connected with removable end walls or end to end with adjacent similar members and having an open top including means for securing cover means thereon, said housing member being arranged with a cool air integral, internal manifold section across one end within said side walls and a heated air integral, internal manifold section across the opposite end and within said side walls and a heat absorber internal section between the two with an air passage permitting exchange of heat to air passing through said heat absorber internal section, each said internal manifold having a cross-sectional dimension greater than said air passage through said heat absorber passage whereby the flow of air through said manifold is at a rate of flow less than the rate through absorber; b. means for forming an opening in at least one side wall in said cool air manifold section arranged to mate with a similar opening in an adjacent member, and means for forming an opening in at least one side wall in said heated air manifold section arranged to mate with a similar opening in an adjacent member; c. means for sealing together adjacent units at mated cool air openings forming an internal manifold for both members; and d. means for sealing together adjacent units, at mated heated air openings forming an internal manifold for both members.
