Abstract
Abstract A solar heating panel for collecting solar heat energy and method for making same having a heat insulative substrate with a multiplicity of grooves and structural supporting ribs formed therein covered by a thin, flexible heat conductive film to form fluid conducting channels which in turn are connected to manifolds from which fluid is directed into the channels and heated fluid is removed therefrom.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
255 words
A solar panel comprising: a self-supporting heat insulative substrate having two ends and a multiplicity of substantially parallel grooves formed on one side of said substrate between said ends with structurally supporting ribs spaced therebetween; a flexible thin heat conductive foil formed of a first metal material attached to and supported by said ribs of said insulative substrate and covering said multiplicity of grooves on one side of said substrate to form fluid conducting channels, said thin flexible heat conductive foil transmitting heat energy incident thereon to fluid flowing in said fluid flowing conduits; a pair of thin foil strips formed of a second metal material different from said first metal material, one of said strips attached to said one side of said substrate adjacent each of said ends of said substrate and the other one of said pair of strips attached to the other side of said substrate adjacent each of said ends of said substrate; and a fluid conducting manifold formed from said second metal material attached to each end of said substrate and communicating with said fluid conducting channels, said fluid conducting manifold having a slot therealong, said slot having one edge soldered to said one of said foil strips attached to said one side of said substrate and the other edge soldered to said other one of said foil strips attached to the other side of said insulative substrate whereby one fluid conducting manifold introduces fluid into said fluid conducting channels and the other fluid conducting manifold receives heated fluid therefrom.
Claim 2
Dependent Claim
255 words
A solar panel comprising: a self-supporting heat insulative substrate having two ends and a multiplicity of substantially parallel grooves formed on one side of said substrate between said ends with structurally supporting ribs spaced therebetween; a flexible thin heat conductive foil formed of a first metal material attached to and supported by said ribs of said insulative substrate and covering said multiplicity of grooves on one side of said substrate to form fluid conducting channels, said thin flexible heat conductive foil transmitting heat energy incident thereon to fluid flowing in said fluid flowing conduits; a pair of thin foil strips formed of a second metal material different from said first metal material, one of said strips attached to said one side of said substrate adjacent each of said ends of said substrate and the other one of said pair of strips attached to the other side of said substrate adjacent each of said ends of said substrate; and a fluid conducting manifold formed from said second metal material attached to each end of said substrate and communicating with said fluid conducting channels, said fluid conducting manifold having a slot therealong, said slot having one edge soldered to said one of said foil strips attached to said one side of said substrate and the other edge soldered to said other one of said foil strips attached to the other side of said insulative substrate whereby one fluid conducting manifold introduces fluid into said fluid conducting channels and the other fluid conducting manifold receives heated fluid therefrom.
Claim 3
Dependent Claim
67 words
