<p>A solar collector assembly (10) is capable of directing an extremely thin film of water in direct contact with a collector sheet (19), the film being formed and regulated by air cushion layers (20, 18 and 22) coextensive with the passage or course of water adjacent and in contact with the collector sheet; the pressure of the air cushion layers against the collector sheet and water film is closely regulated both by the pressure of air in the air cushion layers and the relative tension applied to the collector sheet and layers by the outer peripheral connector and frame assembly. A form of connector and frame assembly (16) has been devised to establish both the desired spacing and tension on the sheets (18, 19, 20 and 22) while permitting releasable but secure connection of the sheets and layers in place within the frame and simultaneously provide the necessary communication with water inlet and outlet headers (50,51:61,62) and air supply (40a, 40,41).</p> |
