In a solar heat collector, a corrugated screen or a transverse series of perforated plates, on the underside of a heat absorber plate and heated by conduction and radiation from the absorber plate. The screen or perforated plates increase the surface area for heat transfer, especially to air, and produce turbulence of the heat transfer medium to increase heat transfer therefrom and also from the underside of the absorber plate. The screen or perforated plates are also adapted to support the heat absorber plate in a desired position.
