Abstract
Abstract A solar collector assembly having within its housing a series of radiant energy entrapping collector elements, each having an energy absorbing base, a generally semicylindrical upwardly open reflector with concave, upper, receptor-reflector surfaces and convex lower receptor surfaces, a collector and radiation entrapping receptor projecting up in said reflector into the radiation reflection pattern of the concave surfaces. These elements form elongated fluid flow heat exchange passages.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
111 words
A solar collector assembly comprising: a housing having a tray and a radiant energy transmitting cover thereover; and a series of solar collector elements side-by-side in said tray, each said element comprising an elongated metallic extrusion having the following features: an elongated base having an underside support surface and an upper radiant energy absorbing surface; an elongated, generally T-shaped, radiant energy absorbing collector projecting upwardly above said base; a pair of elongated arcuate generally quarter-cylindrical reflector members projecting upwardly and outwardly from said base astraddle of said collector, having concave inner reflector surfaces oriented generally toward said collector to reflect radiant solar energy to said collector, and having convex outer surfaces.
Claim 2
Dependent Claim
111 words
A solar collector assembly comprising: a housing having a tray and a radiant energy transmitting cover thereover; and a series of solar collector elements side-by-side in said tray, each said element comprising an elongated metallic extrusion having the following features: an elongated base having an underside support surface and an upper radiant energy absorbing surface; an elongated, generally T-shaped, radiant energy absorbing collector projecting upwardly above said base; a pair of elongated arcuate generally quarter-cylindrical reflector members projecting upwardly and outwardly from said base astraddle of said collector, having concave inner reflector surfaces oriented generally toward said collector to reflect radiant solar energy to said collector, and having convex outer surfaces.
Claim 3
Dependent Claim
113 words
A solar energy collector element comprising an elongated metallic extrusion having the following features: an elongated base having an underside support surface and an upper radiant energy absorbing surface; an elongated, T-shaped radiant energy absorbing collector projecting upwardly above said base; a pair of elongated arcuate generally quarter-cylindrical reflector members projecting upwardly and outwardly from said base astraddle of said collector, having concave inner reflector surfaces oriented generally toward said collector to reflect radiant solar energy to said collector, and having convex outer surfaces; and the surfaces of said collector, said convex outer surfaces of said members, and said upper base surface being multioriented for maximizing surface area and radiant energy absorption thereby.
