Abstract
Abstract 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
115 words
In a solar heat collector: a housing having a cover transparent to solar radiant energy; a heat absorbing and radiating plate disposed in generally parallel spaced relation to said cover; foraminous means attached to the underside of said heat absorbing plate in heat conductive and supporting relationship; and insulation means disposed beneath said absorber plate and said foraminous means for supporting said absorber plate and said foraminous means; and means for guiding a gas to be heated into engagement with the top surface of said heat absorbing plate and into turbulent engagement with the bottom surface of said absorbing plate and with said foraminous means, for conducting heat from said absorbing plate to said gas.
Claim 2
Dependent Claim
115 words
