Abstract
Abstract The solar heat absorber includes a frame and a plurality of clear panels respectively overlying a plurality of arcuate shaped heat collecting plates supported by the frame and compartmented each from the next by separators forming dead air spaces or cells. At least one continuous fluid passage tube is soldered to each plate and provides a cool tube inlet and a feedback hot tube outlet section for each plate whereby some of the heat in the hot tube section is transferred through the cell to its cool tube section within each cell prior to discharge of the fluid out the hot tube section. Each of the cells is at a temperature different than the temperature of an adjacent cell and a heat sink is provided in contact with each panel to substantially equalize the temperature of the panels.
