ABSTRACT:
This solar heater has a plenum enclosure in the middle of a housing which contains partially overlapping, inclined, blackened aluminum sheets on opposite sides of the plenum enclosure. The interior of the plenum enclosure is divided into an inlet plenum and an outlet plenum, which communicate respectively with the opposite ends of air passages between the sheets. For optimum conversion of solar radiation into heating of the air, each sheet is not more than 0.010 inch thick and the spacing between neighboring sheets where they overlap is not more than 0.025 inch. Air is circulated at a high enough rate to absorb heat from the plates substantially as fast as it is produced in the plates by solar radiation.
