Solar thermal tube plate heat exchanger

An apparatus for absorbing heat from the sun and dissipating heat to the atmosphere at night;

• said apparatus comprising:
• a generally flat thermally conductive sheet which serves as a back plate;
• one or more tubular fluid conduit or conduits;
• a generally rectangular thermally conductive cap for covering and pressing said conduit or conduits against said sheet;
• said cap having a length and a width generally covering the one or more of said conduit or conduits;
• said cap not covering the entire sheet if used in plurality;
• said cap not contiguous to each other in the parallel if used in plurality;
• and
• a means for fastening the thermally conductive cap to said thermally conductive sheet;
• thereby covering said one or more conduit or conduits and pressing them against said sheet;
• said cap fastened to that side of said sheet which is exposed to the sun and atmosphere.
