Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
185 words
A device for receiving and storing solar energy comprising a coating having a planar area adapted to strongly absorb solar energy where the coating possesses low emissivity in the infra-red region, a crystalline storage mass having a planar area substantially equal to the planar area of said coating and wherein said storage mass has a phase change point at a predetermined temperature equal to the desired working temperature to which the storage mass is to be exposed, said coating being situated above said storage mass, and an automatic vaporization and condensation heat rectifier means between said coating and said heat storage mass having a planar area substantially equal to the planar area of said coating and said storage mass and thermally connecting said coating and said storage mass for restricting flow of heat in one direction from said coating to said storage mass whereby heat absorbed by said coating is transferred to said storage mass where it may be subsequently released during a phase change and whereby a minimum of heat radiated back to said coating from said storage mass is emitted to free space.
Claim 2
Independent Claim
185 words
A device for receiving and storing solar energy comprising a coating having a planar area adapted to strongly absorb solar energy where the coating possesses low emissivity in the infra-red region, a crystalline storage mass having a planar area substantially equal to the planar area of said coating and wherein said storage mass has a phase change point at a predetermined temperature equal to the desired working temperature to which the storage mass is to be exposed, said coating being situated above said storage mass, and an automatic vaporization and condensation heat rectifier means between said coating and said heat storage mass having a planar area substantially equal to the planar area of said coating and said storage mass and thermally connecting said coating and said storage mass for restricting flow of heat in one direction from said coating to said storage mass whereby heat absorbed by said coating is transferred to said storage mass where it may be subsequently released during a phase change and whereby a minimum of heat radiated back to said coating from said storage mass is emitted to free space.
Claim 3
Dependent Claim
103 words
A device according to claim 1 wherein said heat rectifier means comprises a closed chamber having a heat carrier therein in gaseous and condensate form and condensate transfer means to transfer said heat carrier in condensate form from said storage mass to said coating whereby when said heat carrier on said coating is heated by absorbed solar energy, it will vaporize and transfer heat from said coating to said crystalline mass where it is cooled and condensed and whereby when said coating is at a temperature below the vaporization temperature of said carrier, no heat will flow from said mass to said coating.
