Abstract
A solar heat exchanger comprises: A. a base and an extended surface thereon for facing frontwardly toward the sun, B. means communicating with said surface to conduct liquid to flow in dispersed condition adjacent said surface, and C. a sheet overlying said surface and spaced therefrom sufficiently closely to cooperate therewith for filming the flowing liquid, said sheet adapted to receive solar radiation for promoting heat transfer to the filmed and flowing liquid.

In a solar heat exchanger, the combination comprising
- a. a base and an extended metallic surface thereon for facing frontwardly toward the sun, the base including plastic material at the rear side of said metallic surface,
- b. means communicating through said plastic material and with said surface to conduct liquid to flow in dispersed condition adjacent the front side of said surface, and
- c. a sheet overlying said surface and spaced therefrom sufficiently closely to cooperate therewith for filming the flowing liquid, said sheet adapted to receive solar radiation for promoting heat transfer to the filmed and flowing liquid,
- d. a translucent panel overlying said sheet and spaced therefrom, and
- e. said base having a portion extending at the peripheries of said panel and sheet to enclose said space therebetween, there being vent means in said base portion to release heat from said enclosed space.
