Abstract
Abstract A black plate absorber divides the chamber of a solar collector into upper and lower spaces, both of which are provided with inlets and outlets for a heat exchange medium. Heat losses through the side walls are reduced by providing, between the chamber and the side walls, side conduits which have inlets and outlets for a heat exchange medium.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
260 words
A solar collector for heating air or other gaseous heat exchange media, comprising, an enclosure having a chamber formed by walls and a cover which is transparent to radiant solar energy, primary conduit means located within the enclosure for providing a primary flow passage for a heat exchange medium, said primary conduit means having an upper surface which is absorptive of solar radiation, said primary conduit being spaced from the cover to provide a first space between the primary conduit means and the cover, said primary conduit means being spaced from the bottom of the chamber to provide a second space between the primary conduit means and the bottom of the chamber, said primary conduit means having inlet and outlet means enabling a heat exchange medium to flow therethrough to remove heat from the chamber, said first space having inlet and outlet means enabling heat exchange medium to flow therethrough to remove heat from the chamber and reduce heat losses through said cover, said second space means having inlet and outlet means enabling a heat exchange medium to flow therethrough to remove heat from the chamber and reduce heat transmission to the bottom of the enclosure, a common inlet chamber which contains a gaseous heat exchange medium and is in communication with all of said inlet means, said inlet means of said primary conduit means being substantially larger than the inlet means of said first and second spaces to provide a substantially greater quantitative flow of the gaseous heat exchange medium through said primary conduit means than through said spaces.
Claim 2
Dependent Claim
260 words
A solar collector for heating air or other gaseous heat exchange media, comprising, an enclosure having a chamber formed by walls and a cover which is transparent to radiant solar energy, primary conduit means located within the enclosure for providing a primary flow passage for a heat exchange medium, said primary conduit means having an upper surface which is absorptive of solar radiation, said primary conduit being spaced from the cover to provide a first space between the primary conduit means and the cover, said primary conduit means being spaced from the bottom of the chamber to provide a second space between the primary conduit means and the bottom of the chamber, said primary conduit means having inlet and outlet means enabling a heat exchange medium to flow therethrough to remove heat from the chamber, said first space having inlet and outlet means enabling heat exchange medium to flow therethrough to remove heat from the chamber and reduce heat losses through said cover, said second space means having inlet and outlet means enabling a heat exchange medium to flow therethrough to remove heat from the chamber and reduce heat transmission to the bottom of the enclosure, a common inlet chamber which contains a gaseous heat exchange medium and is in communication with all of said inlet means, said inlet means of said primary conduit means being substantially larger than the inlet means of said first and second spaces to provide a substantially greater quantitative flow of the gaseous heat exchange medium through said primary conduit means than through said spaces.
Claim 3
Dependent Claim
64 words
The solar collector of claim 1 wherein the second space includes a plurality of upper channels and a plurality of lower channels, said inlet means for the second space including upper openings leading to said upper channels and lower openings leading to said lower channels, said upper openings for each upper channel having a larger area than said lower openings for each lower channel.
Claim 4
Dependent Claim
35 words
The solar collector of claim 1 wherein the total area of said inlet means to the first and second spaces is less than the total area of said inlet means to the primary conduit means.
Claim 5
Dependent Claim
26 words
The solar collector of claim 1 having a corrugated member in said second space and provided with peaks which underlie and support the primary conduit means.
Claim 6
Dependent Claim
31 words
The solar collector of claim 1 wherein said primary conduit means is formed to a pair of adjacent sheets having mutually contacting longitudinally extending areas and mutually spaced longitudinally extending areas.
Claim 7
Dependent Claim
27 words
The solar collector of claim 1 wherein the walls of the enclosure have spaced-apart laterally-projecting external-spacers for reducing heat transfer from the walls to an adjacent structure.
Claim 8
Dependent Claim
46 words
The solar collector of claim 1 having side conduit means extending alongside the chamber between said chamber and a said wall, said conduits having inlet and outlet means enabling a heat exchange medium to flow therethrough to reduce heat losses from the chamber through the walls.
Claim 9
Dependent Claim
22 words
The solar collector of claim 7 wherein the outlet means of the side conduit includes an opening leading to said first space.
Claim 10
Dependent Claim
240 words
A solar collector for heating air or other gaseous heat exchange media, comprising, an enclosure having a chamber formed by walls and a cover which is transparent to radiant solar energy, primary conduit means located within the enclosure for providing a primary flow passage for a heat exchange medium, said primary conduit means having an upper surface which is absorptive of solar radiation, said primary conduit being spaced from the cover to provide a first space between the primary conduit means and the cover, said primary conduit means being spaced from the bottom of the chamber to provide a second space between the primary conduit means and the bottom of the chamber, said primary conduit means having inlet and outlet means enabling a heat exchange medium to flow therethrough to remove heat from the chamber, said first space having inlet and outlet means enabling heat exchange medium to flow therethrough to remove heat from the chamber and reduce heat losses through said cover, said second space means having inlet and outlet means enabling a heat exchange medium to flow therethrough to remove heat from the chamber and reduce heat transmission to the bottom of the enclosure, said primary conduit means being formed of a pair of adjacent sheets having mutually contacting longitudinally extending areas and mutually spaced longitudinally extending areas, and a corrugated member in said second space and provided with peaks which underlie and support the primary conduit means.
Claim 11
Dependent Claim
240 words
A solar collector for heating air or other gaseous heat exchange media, comprising, an enclosure having a chamber formed by walls and a cover which is transparent to radiant solar energy, primary conduit means located within the enclosure for providing a primary flow passage for a heat exchange medium, said primary conduit means having an upper surface which is absorptive of solar radiation, said primary conduit being spaced from the cover to provide a first space between the primary conduit means and the cover, said primary conduit means being spaced from the bottom of the chamber to provide a second space between the primary conduit means and the bottom of the chamber, said primary conduit means having inlet and outlet means enabling a heat exchange medium to flow therethrough to remove heat from the chamber, said first space having inlet and outlet means enabling heat exchange medium to flow therethrough to remove heat from the chamber and reduce heat losses through said cover, said second space means having inlet and outlet means enabling a heat exchange medium to flow therethrough to remove heat from the chamber and reduce heat transmission to the bottom of the enclosure, said primary conduit means being formed of a pair of adjacent sheets having mutually contacting longitudinally extending areas and mutually spaced longitudinally extending areas, and a corrugated member in said second space and provided with peaks which underlie and support the primary conduit means.
