Abstract
Abstract A generally rectangular solar heat collector block or module adapted to operate with its narrow side in a generally vertical position. One face of the collector block is adapted to receive direct sun rays. The ray receiving face having a reflector surface commencing at a position closely adjacent the front and top of the block and terminating adjacent the rear and bottom of the block. A duct is disposed transversely in the bottom of the block and has a depth substantially coextensive with the depth of the block. Insulation is provided in the block rearwardly of the reflector surface. The reflector surface comprises a plurality of adjoining, different angled reflective surfaces which are arranged and constructed to dispense reflected sun heat rays substantially uniformly over an extended portion of the full depth of the duct. The module just defined is adapted to be used in multiples and arranged side-by-side and in vertical banks to form a wall panel for collecting solar heat. The individual ducts of each module combine to form a single long duct for carrying the collected heat to any desired area for usage of that heat.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
218 words
A solar collector comprising a substantially vertically disposed rectangularly shaped unit formed from a block of rigid insulating material and defining a vertical front, a spaced apart vertical back, a horizontal top and a spaced apart horizontal bottom, the solar collector unit disposed in such a manner that said front receives the direct sun's rays, a sun reflecting surface formed on said insulating material within the front of said unit, said block of material being recessed to form a horizontally disposed duct positioned in the bottom of said unit, means covering the top of said duct and for receiving solar energy said duct extending substantially the full depth of the collector and utilized to receive the sun's heat rays from the reflecting surface formed within the front of said unit, and said sun reflecting surface formed of a plurality of flat surfaces disposed at different angles relative to the vertical front surface and adjoining one another in forming a continuous surface, and a remaining continuously curved surface joining the last of said flat surfaces and extending down to a juncture with the rearward end of the duct, and the angles of said reflecting flat surfaces and the contour of the curved surface being such that the duct receives concentrated reflected sun heat rays over a substantial extent thereof.
Claim 2
Dependent Claim
218 words
A solar collector comprising a substantially vertically disposed rectangularly shaped unit formed from a block of rigid insulating material and defining a vertical front, a spaced apart vertical back, a horizontal top and a spaced apart horizontal bottom, the solar collector unit disposed in such a manner that said front receives the direct sun's rays, a sun reflecting surface formed on said insulating material within the front of said unit, said block of material being recessed to form a horizontally disposed duct positioned in the bottom of said unit, means covering the top of said duct and for receiving solar energy said duct extending substantially the full depth of the collector and utilized to receive the sun's heat rays from the reflecting surface formed within the front of said unit, and said sun reflecting surface formed of a plurality of flat surfaces disposed at different angles relative to the vertical front surface and adjoining one another in forming a continuous surface, and a remaining continuously curved surface joining the last of said flat surfaces and extending down to a juncture with the rearward end of the duct, and the angles of said reflecting flat surfaces and the contour of the curved surface being such that the duct receives concentrated reflected sun heat rays over a substantial extent thereof.
Claim 3
Dependent Claim
27 words
A device as defined in claim 1 in which said plurality of flat surfaces of said sun reflecting surface being formed of at least three flat surfaces.
Claim 4
Dependent Claim
104 words
A device as set forth in claim 2 in which the first or uppermost of the three flat surfaces is disposed at an angle in the order of 35° relative to the vertical, the next of the three flat surfaces is substantially the same length as the first of said flat surfaces and is disposed at an angle in the order of 32° relative to the vertical, and the third or lowermost of the three flat surfaces is substantially twice the length of the first of said flat surfaces and is disposed at an angle in the order of 28° relative to the vertical.
Claim 5
Dependent Claim
101 words
A device as set forth in claim 2 in which the first or uppermost of the three flat surfaces is in the order of 31/2" in length and has an angle in the order of 35° relative to the vertical, the second or middle of the three flat surfaces is in the order of 31/2" in length and has an angle in the order of 32° relative to the vertical, and the third or lowermost of the three flat surfaces being in the order of 77/10" in length and has an angle in the order of 28° relative to the vertical.
Claim 6
Dependent Claim
33 words
A device as set forth in claim 1 including a front cover which permits the passage of sun rays with a minimum of refraction and substantially confines generated heat within the solar collector.
