Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
172 words
A solar collector comprising: an array of a plurality of spaced tubes for conducting heat exchange fluid; means to collect energy and transfer same to said tubes, said means comprising finplanks each of which has a portion inwardly and exteriorly respectively of their mating edges contoured with one portion adapted to be placed about one side and an opposite portion adapted to be placed about an opposite side of the tubes when mating edges of one finplank with another finplank, said mating edges having flanges one of which is recessed below the surface of the one finplank and another of which is an extension of the surface of the another finplank each of which has prepunched holes that will align when their respective contoured portions of the finplank edges are encircling one of said tubes: and fastener means inserted through the aligned holes of said flanges to draw said finplank edges into compressive contact with said one of said tubes whereby said finplanks provide thermal conductivity to said one of said tubes.
