Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
A solar heat collector for heating a fluid, comprising an open-topped container, a panel in said container positioned to be contacted by solar radiation entering the container through the open top, said panel comprising a number of collector plates disposed substantially in edge-to-edge relation in a common plane, fluid-conducting conduit disposed in engagement with said panel along adjoining edges of said plates, and gripping means on said plates encircling adjacent sections of said conduit for retaining the conduit in efficient heat-conducting relation with the plates, said gripping means comprising slotted areas disposed in each plate adjacent an adjoining edge and defining gripping members therebetween, the gripping members of a respective plate being interlocked with gripping members on an adjacent plate and defining therewith a channel within which said conduit is located, and a transparent cover disposed over the open top of the container and transmissive to solar radiation.
Claim 2
Dependent Claim
148 words
A solar heat collector for heating a fluid, comprising an open-topped container, a panel in said container positioned to be contacted by solar radiation entering the container through the open top, said panel comprising a number of collector plates disposed substantially in edge-to-edge relation in a common plane, fluid-conducting conduit disposed in engagement with said panel along adjoining edges of said plates, and gripping means on said plates encircling adjacent sections of said conduit for retaining the conduit in efficient heat-conducting relation with the plates, said gripping means comprising slotted areas disposed in each plate adjacent an adjoining edge and defining gripping members therebetween, the gripping members of a respective plate being interlocked with gripping members on an adjacent plate and defining therewith a channel within which said conduit is located, and a transparent cover disposed over the open top of the container and transmissive to solar radiation.
Claim 3
Dependent Claim
30 words
A solar heat collector as set forth in claim 1 wherein said gripping members are shaped to substantially semicircular configurations and are disposed in closely encircling relation to said conduit.
Claim 4
Dependent Claim
31 words
A solar heat collector as set forth in claim 2 wherein said gripping members on each respective plate are connected together by an integral lip, which lips on adjacent plates abut.
Claim 5
Dependent Claim
101 words
A collector plate for a solar heat collector panel, comprising a substantially flat sheet of good thermal conductivity material, said sheet having at least one edge portion formed to a reversely curved semicircular configuration, said edge portion having a series of perforations therein spaced at intervals throughout the length thereof, said perforations being slots which extend perpendicular to the adjacent edge of the sheet, said slots terminating in spaced relation to the adjacent edge of the sheet to form an unbroken edge portion on said sheet, which edge portion is bent to form a lip directed outwardly from said semicircular portion.
Claim 6
Dependent Claim
101 words
A collector plate for a solar heat collector panel, comprising a substantially flat sheet of good thermal conductivity material, said sheet having at least one edge portion formed to a reversely curved semicircular configuration, said edge portion having a series of perforations therein spaced at intervals throughout the length thereof, said perforations being slots which extend perpendicular to the adjacent edge of the sheet, said slots terminating in spaced relation to the adjacent edge of the sheet to form an unbroken edge portion on said sheet, which edge portion is bent to form a lip directed outwardly from said semicircular portion.
Claim 7
Dependent Claim
104 words
A collector panel for a solar heat collecting device, comprising at least two substantially flat collector plates of good heat conductive material disposed in a common plane in edge-to-edge relation, said plates having their adjacent edge portions formed to a reversely curved semicircular configuration and having a series of perforations therein spaced at intervals throughout the length of said edge portions to form gripping members between the perforations, the gripping members of one plate being disposed within aligned perforations in the adjacent plate whereby the gripping members of the two adjacent plates form a channel extending parallel with the adjacent edges of the plates.
Claim 8
Dependent Claim
104 words
A collector panel for a solar heat collecting device, comprising at least two substantially flat collector plates of good heat conductive material disposed in a common plane in edge-to-edge relation, said plates having their adjacent edge portions formed to a reversely curved semicircular configuration and having a series of perforations therein spaced at intervals throughout the length of said edge portions to form gripping members between the perforations, the gripping members of one plate being disposed within aligned perforations in the adjacent plate whereby the gripping members of the two adjacent plates form a channel extending parallel with the adjacent edges of the plates.
Claim 9
Dependent Claim
36 words
A collector panel as set forth in claim 5 wherein a section of fluid-conducting tubing is disposed with said channel with the gripping members being disposed in heat-conductive relation with the outer surface of the tubing.
Claim 10
Dependent Claim
60 words
A collector panel as set forth in claim 6 wherein said perforations are slots which extend perpendicular to the adjacent edge of the respective plates and terminate in spaced relation to the respective edge to form an unbroken lip extending along said respective edge, the lips on adjacent plates abutting to form means for preventing mechanical expansion of the channel.
