Solar heat collector

A solar heat collector adapted to be disposed across an open window area in an enclosure, said collector comprising a pair of transparent panes;

• means for holding said panes in a spaced relation and defining an insulating chamber disposed between said panes, said chamber having an air inlet and an air outlet for communicating said chamber with the interior of the enclosure;
• a layer of heat reflecting material disposed on one of said transparent panes to reduce heat loss therethrough;
• a plurality of fins transversely disposed within said chamber, each of said fins defining a heat reflective surface on one side thereof and having an energy absorbing material on the other side thereof;
• and means for collectively varying the angular orientation of said fins within said chamber such that either the reflective or absorbent sides of said fins can be collectively directed toward the sun at a selected and variable angle thereby regulating the warm air flow from said chamber to said enclosure through said air outlet.

A solar heat collector adapted to be disposed across an open window are in an enclosure, said collector comprising an internal transparent pane;

• an external transparent pane;
• means for holding said panes in a spaced relation across said window area to define an insulating chamber disposed between said panes, said chamber having an air inlet and an air outlet communicating said chamber with said enclosure;
• a plurality of fins transversely disposed between said panes within said chamber, each of said fins having an energy reflecting side and an energy absorbing side;
• a layer of heat reflective material disposed on the interior side of said internal transparent pane to reduce heat loss through said pane from said chamber to said enclosure;
• and means for collectively varying the angular orientation of said fins within said chamber such that either the reflective or absorbent sides of said fins can be collectively directed toward the sun at a selected and variable angle thereby regulating the warm air flow from said chamber to said enclosure through said air outlet.
