Abstract
Abstract An omni-directional solar heat collector having a transparent, spherical outer shell, a spherical inner shell within the outer shell containing a plurality of light magnifying lenses spaced along the periphery thereof, and a plurality of heat collecting elements within said inner shell spaced from the magnifying lenses so that maximum light and heat intensity focuses upon said elements.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
114 words
A solar heat collector comprising: a transparent, spherical outer shell; a spherical inner shell within said outer shell and spaced therefrom containing a plurality of light intensification means spaced along the periphery thereof; a plurality of heat collecting elements within said inner shell spaced from the light intensification means; and inlet and outlet headers communicating with said heat collecting elements and passing through said inner and outer shells for circulation of a heat transfer medium through said heat collecting elements, wherein said heat collecting elements comprise a circuitous array of passageways contained within a plurality of metal plates intersecting within said inner shell, said passageways being connected to a common inlet and outlet header.
Claim 2
Dependent Claim
114 words
A solar heat collector comprising: a transparent, spherical outer shell; a spherical inner shell within said outer shell and spaced therefrom containing a plurality of light intensification means spaced along the periphery thereof; a plurality of heat collecting elements within said inner shell spaced from the light intensification means; and inlet and outlet headers communicating with said heat collecting elements and passing through said inner and outer shells for circulation of a heat transfer medium through said heat collecting elements, wherein said heat collecting elements comprise a circuitous array of passageways contained within a plurality of metal plates intersecting within said inner shell, said passageways being connected to a common inlet and outlet header.
Claim 3
Dependent Claim
37 words
A collector according to claim 1 wherein said light intensification means are magnifying lenses and wherein the heat collecting elements are spaced from the magnifying lenses so that maximum light and heat intensity focuses upon said elements.
Claim 4
Dependent Claim
38 words
A collector according to claim 1 wherein said passageways are contained in three circular plates perpendicular to each other and intersecting at a common point centrally of said inner shell, wherein each plate is in a separate plane.
Claim 5
Dependent Claim
25 words
A collector according to claim 1 including a plurality of reflective surfaces spaced from said outer shell for reflecting light rays upon said outer shell.
Claim 6
Dependent Claim
32 words
A collector according to claim 1 including a temperature sensing device communicating with the inlet and outlet headers for regulating the flow of the heat transfer medium through the heat collecting elements.
