Abstract
Abstract A solar energy collector formed of an inclined corrugated radiant heat absorbing panel for absorbing direct and reflected solar radiation having a plurality of air passageways formed by the convolutions of the corrugations, an air intake manifold and an air exhaust manifold connected to the passageways in said panel, an inflatable air-tight bag surrounding the collector assembly and a source of pressurized air connected to said air inlet manifold for pressurizing the system and for forcing air through the heat absorbing panel for heating the same.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
177 words
A pressurized and inflatable solar energy collector comprising a radiating heat absorbing panel assembly formed of a central panel of a plurality of longitudinally disposed air passageways and end frames integral with said central panel formed perpendicular to said central panel, first and second manifold sections in fluid communication with said air passageways, end cap sections adapted to fit over said first and second manifold sections and said end frames, at least one of said end cap sections including an air inlet and air outlet port, an air inlet duct connected to said air inlet port in fluid communication with said first manifold section, an air exhaust duct connected to said air outlet port in fluid communication with said second manifold section, an inflatable air-tight bag forming the outer layer of said collector and a source of pressurized air connected to said air inlet duct for inflating said bag and pressurizing said assembly and providing air flow between said air inlet ducts, said first manifold section, said air passageways, said second manifold section, and said outlet duct.
Claim 2
Dependent Claim
177 words
A pressurized and inflatable solar energy collector comprising a radiating heat absorbing panel assembly formed of a central panel of a plurality of longitudinally disposed air passageways and end frames integral with said central panel formed perpendicular to said central panel, first and second manifold sections in fluid communication with said air passageways, end cap sections adapted to fit over said first and second manifold sections and said end frames, at least one of said end cap sections including an air inlet and air outlet port, an air inlet duct connected to said air inlet port in fluid communication with said first manifold section, an air exhaust duct connected to said air outlet port in fluid communication with said second manifold section, an inflatable air-tight bag forming the outer layer of said collector and a source of pressurized air connected to said air inlet duct for inflating said bag and pressurizing said assembly and providing air flow between said air inlet ducts, said first manifold section, said air passageways, said second manifold section, and said outlet duct.
Claim 3
Dependent Claim
23 words
