Solar collector
A solar collector of generally improved design is provided wherein the collector element comprises a flat absorber plate formed of two sheets of a conductive metal treated in a bonding process under heat and pressure with portions of the sheets spaced in such a way as to provide a sinuous passage from one end of the collector to the other with flat portions of the plate between said passages. The collector has a double glazing over the absorber plate to provide an air space between the sheets of glass and between the glazing and the absorber plate. A feature of the invention is in the fabrication of the collector utilizing novel metal extruded frame members combined with wood frame members. This combination provides an effective means for sealing the elements against the weather and for holding the various elements in correct alignment as well as resisting loads of snow or sleet. The design of the bonded absorber plate insures that every molecule of water is treated in the same way and in a typical embodiment, the temperature is raised from 4* F. To 10* F in each pass.
