Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
76 words
A solar collector comprising: fluid conduit means including a plurality of tubes; and means to absorb solar energy and transfer same to said tubes, said means to absorb solar energy consisting of adjacent finplanks each having locking tongues cooperating to encircle the tubes at edges of the adjacent finplanks, said finplanks also having lips extending away from the tubes, and clip means encircling said lips and closing said edges of the adjacent finplanks about said tubes.
Claim 2
Dependent Claim
76 words
A solar collector comprising: fluid conduit means including a plurality of tubes; and means to absorb solar energy and transfer same to said tubes, said means to absorb solar energy consisting of adjacent finplanks each having locking tongues cooperating to encircle the tubes at edges of the adjacent finplanks, said finplanks also having lips extending away from the tubes, and clip means encircling said lips and closing said edges of the adjacent finplanks about said tubes.
Claim 3
Dependent Claim
58 words
The structure of claim 1 and further characterized as a plurality of finplanks whose opposite edges are configured to interlock with other finplanks by use of said plurality of tubes to form a contiguous surface acting as a solar heat collector for heating fluid circulating in said tubes from and to headers at each end of the structure.
