Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
74 words
A solar energy collector comprising an open-topped receptacle, a panel in said receptacle positioned to be contacted by solar radiation entering the receptacle, at least one integral fluid conduit on said panel, said fluid conduit comprising a groove recessed within the panel and having a substantially annular cross-sectional configuration with a seam at the open side thereof, a weld closing said seam, and means for connecting said conduit to a source of circulating fluid.
Claim 2
Dependent Claim
74 words
A solar energy collector comprising an open-topped receptacle, a panel in said receptacle positioned to be contacted by solar radiation entering the receptacle, at least one integral fluid conduit on said panel, said fluid conduit comprising a groove recessed within the panel and having a substantially annular cross-sectional configuration with a seam at the open side thereof, a weld closing said seam, and means for connecting said conduit to a source of circulating fluid.
Claim 3
Dependent Claim
69 words
A solar energy collector as set forth in claim 1 wherein said panel has a substantially planar surface to be contacted by said solar radiation entering the receptacle, said groove is recessed in the panel beneath said planar surface, and said weld seals said seam throughout its length and provides a continuous integral conduit through which said fluid may flow in direct thermal contact with material of the panel.
Claim 4
Dependent Claim
67 words
A radiation-absorbing panel for a solar energy collector comprising a metal sheet having a side thereof disposed substantially in a plane for contact by solar radiation, said sheet having at least one integral fluid conduit thereon, said fluid conduit comprising a groove recessed within the sheet and having a substantially annular cross-sectional configuration with a seam at the open side thereof, and a weld closing said seam.
Claim 5
Dependent Claim
67 words
A radiation-absorbing panel for a solar energy collector comprising a metal sheet having a side thereof disposed substantially in a plane for contact by solar radiation, said sheet having at least one integral fluid conduit thereon, said fluid conduit comprising a groove recessed within the sheet and having a substantially annular cross-sectional configuration with a seam at the open side thereof, and a weld closing said seam.
Claim 6
Dependent Claim
63 words
A panel as set forth in claim 3 wherein said sheet has a substantially planar surface to be contacted by said solar radiation, said groove is recessed in the sheet beneath said planar surface, and said weld seals the seam throughout its length and provides a continuous integral conduit through which fluid may flow in direct thermal contact with material of the panel.
