Abstract
Abstract A solar energy collecting device comprising a collector plate. A wall member is attached to the periphery of the collector plate and to the periphery of a panel to form an enclosure. The central portion of the panel is transparent and transmits solar energy therethrough and into the enclosure. A run of tubing passing heat transfer fluid during use is disposed within the chamber. The ends of the tubing pass through an aperture in the wall member. The outside of the enclosure is insulated with polyurethane foam that is applied by spraying process.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
175 words
A solar energy collecting device comprising: a. a collector plate; b. a wall member extending perpendicular from the plane of the collector plate and having first and second spaced apart and inwardly extending flanges aligned with the bottom and top of said wall member respectively, said first flange bearing against the periphery of said collecting plate; c. First means for connecting said collector plate to said first flange; d. a panel having a peripheral portion bearing against a rubber gasket disposed upon the second flange to form an enclosure, said panel having a transparent central portion capable of transmitting solar energy therethrough; e. second means for connecting said panel to said second flange; f. a run of tubing mounted within the enclosure, the wall member of the enclosure having an aperture allowing end portions of the tubing to project from the enclosure whereby fluid can be passed therethrough during use to extract solar energy absorbed in the enclosure; and g. insulating covering the outside of the enclosure excepting said transparent central portion of the panel.
Claim 2
Dependent Claim
