Claims
- 1. A solar collector comprising:
- (a) a perimetric frame defining a substantially open central portion having two spaced, substantially planar sides, said frame also having an internal perimetric flange;
- (b) thin plastic film glazing substantially congruent to said frame covering said sides and fastened to said frame whereby said frame and said glazing cooperate to form a light-weight, high-strength monocoque structure;
- (c) an absorber comprising two substantially congruent thin films being bonded together around their edges to form an envelope having a high surface area to volume ratio, said envelope having a first opening for the introduction of a heat transfer fluid into said envelope and a second opening for the removal of said fluid from said envelope, which absorber is substantially congruent with and fastened to said internal flange so that said absorber is parallel with and spaced from said sides; and
- (d) manifold means for providing a flow of heat transfer fluid through said absorber.
- 2. A collector as described in claim 1, further comprising insulation disposed between said absorber and at least one glazing film said sides defined by said frame, at least a portion of said insulation comprising a rigid insulation material which supports said frame in compression so as to further strengthen said monocoque structure.
- 3. A solar collector of claim 1 wheein the absorber is constructed so that said films are furthe bonded together at a plurality of locations across their surface so as to maintain a high degree of parallelism between said films as said heat transfer fluid flows from said first opening to said second opening thereby assuring that a substantial portion of the surface of said films is wetted by said fluid.
- 4. A solar collector of claim 1 wherein in the absorber, at least one of said films is formed from a metal/plastic laminate.
