Abstract
Abstract A device is described for concentrating solar radiation upon the surface of a helicoidal tube assembly containing a circulating heat transfer medium whereby the energy of said radiation may be collected and utilized. The device consists of a rectangular container wherein is supported a longitudinal plurality of aligned curved reflectors for gathering and concentrating incident solar radiation, multiple vertical relectors to gather low-angle radiation, a convex radiation concentrating reflector beneath said helicoidal tube and a means for damping excess solar radiation. A method is given for the utilization of said solar radiation collector whereby the heated circulating medium provides the means for heating and cooling buildings.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
218 words
A solar radiation collector and concentrator comprising: a. an enclosure assembly formed from weatherproof metal and defining a generally rectangular mounting surface; b. a transparent cover portion for said enclosure assembly; c. a longitudinal plurality of aligned curved reflective surfaces supported within said mounting surface and being operable to reflect incident solar radiation toward a common focal axis extending longitudinally of said enclosure assembly; d. multiple vertical reflectors positioned perpendicular to said plurality of longitudinal aligned curved reflective surfaces and being operable to reflect low-angle solar radiation toward said common focal axis; e. a helicoidal fluid-bearing tube longitudinally mounted within said enclosure assembly and being positioned at the common focal axis of solar radiation reflected from said longitudinal plurality of aligned curved reflective surfaces and at the common focal axis of low-angle solar radiation reflected from said multiple vertical reflectors; f. a convex radiation reflector longitudinally mounted below and along an axis parallel to said helicoidal fluid-bearing tube and being operable to reflect incident and low-angle solar radiation upward onto said helicoidal fluid-bearing tube; g. a transparent coil housing assembly within said enclosure assembly longitudinally mounted above and along an axis parallel to both the helicoidal fluid-bearing tube and the convex radiation relector; and h. means for preventing excess solar radiation from striking said transparent coil housing assembly.
Claim 2
Dependent Claim
218 words
