ABSTRACT:
A versatile, low cost solar heat collecting module made up of a minimum of presized basic parts has a cover portion for passing solar energy into an inner cavity where it is absorbed by a collector plate and converted to heat which in turn heats a stream of air in a flow passage along the back face of the collector plate. Manifold portions at the ends facilitate the moving of a stream of air through each module and an array of interconnected modules are arranged side-by-side in such a way that the flow path for air from inlet to outlet for the array is substantially the same distance. A heat-washing means projects into the flow passage from the back side of the collector plate to cause a turbulence in the air stream, the heat-washing means being provided by a support strap for supporting the collector plate that is bent to project into the flow passage and place a tension in the support strap and collector plate.
