Abstract
Abstract A solar heating panel has a rectangular frame to receive a rectangular metal pan which supports a continuous coil of water tubing which is attached thereto by strips of metal attached to the pan. Preferably, the frame is divided into quadrants by rails. Each quadrant is closed off by a pane of glass cushioned and weather-stripped to the frame and rails. Above the glass is a continuous sheet of a synthetic, highly transparent plastic which is attached to the frame by a gasket. Provision is made for thermal expansion of the various components, for drainage, for prevention of leakage of moisture and for insulation. The panel can be incorporated in a household water heating system and also to heat space. The metal pan has a roughened surface (e.g., pebbled, diamond-embossed) and is painted black. This structure increases the area exposed to the sun, eliminates reflection, interrupts flow of cooling air across the surface of the pan, and reduces the effect of expansion and contraction.

Total Claims: 7
Claim 1
Independent Claim
290 words
A solar collecting panel comprising a frame, said frame having sides, ends and a back, an elongated multicurved tubular coil within said frame and having an inlet and an outlet extending exteriorly of said frame, a solar collecting pan attached to said frame behind said coil, securing means holding said coil in position relative to said pan, a first transparent panel over said coil, first sealing means sealing said first panel to said frame, a second transparent panel spaced above said first panel, and second sealing means attaching said second panel to said frame, said pan having a bottom parallel to and spaced from said back and having upstanding sides fixed to said frame, said first sealing means hermetically sealing said first panel to said pan, one end of said second panel extending outward beyond one end of said frame and said second panel being freely supported to expand and contract in two transverse directions parallel to said back, said second panel being of a plastic material, said first panel being formed of a plurality of panes, and at least one longitudinal and one transverse rail extending between ends and sides of said frame, respectively, and fixed thereto spaced above said pan, said rail comprises a channel, a means in said channel extending between said panes and abutting the underside of said second panel, and means spacing said channel from said pan, said first sealing means weather-stripping and cushioning said panes and said rails and permitting free expansion and contraction of said panes in two transverse directions parallel to said back, said second panel being sealed relative to said frame for weather and thermal air circulation, the space between said panes and said second panel being a dead air space.
