Abstract
Abstract A heat collector and radiator for allowing the absorption of lower atmosphere radiation by the maximizing of the surface area capable of absorbing the diffuse radiation. A plurality of closely spaced tubular elements are disposed in parallelism with relatively narrow web portions interconnecting the adjacent tubular elements and in tangential relationship therewith. The structure is unitarily formed from a polymer material admixed with carbon black or like additive. A header means at each opposite end of the tubular elements/web portions communicates therewith. The structure is selective in the respect that it has an emissivity lower than absorptivity, and is less effected by the incident angle.

Claim 1
Independent Claim
183 words
A mechanism for the collection of heat from solar radiation by the maximizing of the surface area capable of absorbing direct radiation and diffuse radiation and trapping some radiation for purposes of reradiation comprising: a unitary construction of a polymer mixed with a black coloring agent consisting of planar web of a certain thickness and certain width and certain length and a multiplicity of closed-spaced parallel-disposed tubular elements extending across the entirety of the certain web width and throughout the entirety of the certain web length, each tubular element being of circular cross section and having a wall thickness equal to the certain web thickness, the web and each tubular element merging into each other along each respective line of contact with each tubular element projecting upwardly from the web plane, a pair of apertured header tubes of circular cross section extended transversely to and bonded at opposite ends of each of the tubular elements and a tubular communicating adapter extended through each aperture in each header tube and into the interior of a respective tubular element for effecting a communicating connection therebetween.
