Abstract:
1. A solar collector comprising a single piece of plastic formed of one unitary piece with: a polygonal blow-molded top panel forming a top face and having at least three edges; a similarly polygonal blow-molded bottom panel unitarily formed with the top panel, forming a bottom face spaced from the top face, and fitted congruently to the top panel at the edges to form a single flow passage extending between the faces and within the edges, the flow passage being of the same area as at least one of the panels; an array of spaced connecting points unitarily formed on at least one of the panels and extending cross the flow passage into engagement with the other of the panels and each forming a flow-deflecting baffle; and at least four blow-molded connectors unitarily formed with and projecting from at least three of the edges and each unitarily formed with a removable end closure, the panels and edges being so configured that a heat-transfer fluid introduced into one of the connectors and drawn out through another of the connectors flows over the entire surface of the flow passage.
