Abstract
Abstract A solar collector of the type embodying a collector plate with fluid conduits disposed in heat-conductive relation to the plate, and a transparent cover spaced above the plate-conduit assembly, with venting devices being provided in opposite end portions of the assembly for permitting cool air circulation within the space between the plate and cover to maintain the temperature of the collector below an established level.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
A solar energy collector comprising a solar radiation absorbing panel adapted to be positioned to intercept solar radiation and to be heated by absorption of such radiation, a fluid conduit disposed in heat-conductive relation to the panel, a cover transparent to solar radiation mounted over the panel in spaced relation with it, and temperature-responsive means at each end of the panel for providing controlled circulation of air over the surface of the panel to maintain the temperature thereof below a prescribed level, said means including apertures adjacent each end of the panel, and adjustable portions of the panel movable into and out of closing relation to the apertures.
Claim 2
Dependent Claim
108 words
A solar energy collector comprising a solar radiation absorbing panel adapted to be positioned to intercept solar radiation and to be heated by absorption of such radiation, a fluid conduit disposed in heat-conductive relation to the panel, a cover transparent to solar radiation mounted over the panel in spaced relation with it, and temperature-responsive means at each end of the panel for providing controlled circulation of air over the surface of the panel to maintain the temperature thereof below a prescribed level, said means including apertures adjacent each end of the panel, and adjustable portions of the panel movable into and out of closing relation to the apertures.
Claim 3
Dependent Claim
47 words
A solar energy collector as set forth in claim 1 wherein a box-like enclosure encloses the sides and bottom of the collector and includes a base plate spaced beneath the radiation absorbing panel and having apertures therein located in communicating relation to respective apertures in the panel.
Claim 4
Dependent Claim
34 words
A solar energy collector as set forth in claim 2 wherein fan means is positioned adjacent one of said apertures for forcibly moving the air through the space between the panel and the cover.
Claim 5
Dependent Claim
63 words
A solar energy collector as set forth in claim 1 wherein said adjustable portions of the panel each is a baffle movably mounted in closing relation to a respective aperture in the panel, and thermally responsive means is disposed in heat-detecting relation to said panel for moving the baffles to open the apertures when the temperature of the panel exceeds said precribed level.
Claim 6
Dependent Claim
18 words
A solar energy collector as set forth in claim 6 wherein said thermally responsive means comprises a thermostat.
Claim 7
Dependent Claim
47 words
A solar energy collector as set forth in claim 4 wherein said baffles are hingedly connected to said panel and thermostats are mounted on the panel and are operatively connected to said baffles to move the baffles in response to variations in temperature of the collector plate.
Claim 8
Dependent Claim
68 words
A solar energy collector as set forth in claim 4 wherein said panel is a metal having a known coefficient of expansion, said baffles comprise integral portions of said panel, and said thermally responsive means includes a layer of metal disposed upon said baffles and having a coefficient of expansion different from that of the baffles and comprising therewith bimetal elements responsive to temperature changes in said panel.
Claim 9
Dependent Claim
71 words
A solar energy collector module as set forth in claim 1 wherein said panel is a metal having a known coefficient of expansion, said adjustable portions are integral portions of said panel, and said temperature-responsive means includes a layer of metal disposed upon said adjustable portions and having a coefficient of expansion different from that of the adjustable portions and comprising therewith bimetal elements responsive to temperature changes in said panel.
