Energy radiant solar collector

A radiant solar energy collector comprising, in combination:

• a box-like enclosure including a bottom wall, side walls and a cover transparent to radiate energy, said enclosure forming an essentially sealed conduit through which a heat exchange fluid is caused to flow;
• insulation on said bottom wall;
• an energy receiving surface disposed within said enclosure in spaced relationship from said bottom wall and said insulation on said bottom wall, said energy receiving surface comprising a base plate and an absorber comprising a plurality of aluminum strips, said aluminum strips being notched in spaced relationship along the lengths thereof and affixed together to form individual absorber elements of a semi-elliptical shape by bending said strips and securing associated ones of said strips together by reversely folding the notched material thereof against said associated ones of said strips, whereby an absorber having a plurality of individual absorber elements in a honeycomb-like design is provided;
• said energy receiving surface being coated with a dull black coat to promote absorption of solar radiant energy;
• said absorber being affixed to said base plate 0.1875 inches above the top surface thereof;
• and
• wherein said aluminum strips are 0.016 inches in thickness and are 1.4 inches in height, each of said individual semi-elliptical absorber elements having dimensions of 2.5 inches by 4.25 inches.
