Patent ID: 6892724

Claim:
A concentrating solar collector for hot water heating comprising; A rectangular shaped frame having a major dimension and a width, including a bottom surface, vertical end panels and side panels of pre-determined height, A plurality of planar vertical supports for a parabolic reflector surface, An odd numbered plurality of reflector surfaces, An odd numbered plurality of heat absorbing conduits, wherein: said frame is made from a non-conducting substrate having a plurality of inner and outer sheets with at least one corrugated intermediate sheet, said frame substrate is shaped to include a bottom area, folded primary end panels, primary side panels equal to the height of the frame, and inside folded secondary co-extensive side panels, said folded primary end panels each having a plurality of of apertures spaced transversely a distance equal to the distance between focal points of adjacent parabolic curves, said inside folded secondary side panels folded inside of the primary side panels to define at least one folded projection with slot cutouts for containment of said planer vertical supports, said planar supports including an odd numbered plurality of adjacent parabolic shaped cutouts along the top margin, a plurality of reflector surfaces having a pre-selected length and a total reflective width substantially equal to the sum of adjacent parabolic surfaces, each of said apertures in the folded primary end panels centered along a focal line below the upper margins of said folded primary ends panels, and passing through said folded primary end panels for serial connection to a coacting absorber conduit, the first and last of said serially connected absorber conduits connected to inlet and outlet fluid piping respectively.
