ABSTRACT:
A shallow open top sheet metal housing contains thermal insulating material on its side and bottom walls and is covered by a translucent top panel beneath which a multiplicity of translucent tubes in side-by-side contacting relationship provide dead air insulation. Serpentine copper tubing topped by a blackened flat copper sheet is arranged in a plane below and parallel to the plane in which the translucent tubes are positioned. The serpentine copper tubing is adapted for connection with a heated fluid circulating system externally of the collector. In a modification, a Fresnel lens concentrates solar rays on the copper tubing.
