Walker, J E

This fluid sheet solar collector is devised as an assembly to produce a sealed unit which contains an internal collector fluid circulating through a closed loop to pass in a thin sheet over a solar energy absorber surface and to pass in good thermal contact through a self contained heat exchanger to effect a net solar energy derived heat transfer to external devices. The internal collector fluid flows upward in a thin sheet contained between a semi-rigid transparent cover and a solar absorber surface wherein the fluid is heated; and flows downward through a heat exchanger wherein the heat is transferred, the net effect is to maintain a thermokinetic circulation of the fluid with neither fluid conduits nor high thermal conductivity materials required in the heating portion of the assembly. 8 claims, 3 figures.
