ABSTRACT:
A solar energy collector is disclosed which is comprised of a base and a solar energy absorbing element spaced from the base. The solar energy absorbing element has an accordian-like shape including angularly disposed upper ridges and lower valleys interconnected by generally planar surfaces. The lower valleys are positioned immediately adjacent the base. Fluid supply conduits are positioned between the solar energy absorbing element and the base immediately adjacent the upper ridges. The fluid supply conduits are adapted to supply fluid adjacent the solar energy absorbing element upper ridges which fluid may then flow along the planar surfaces until dropping off the lower valleys onto the base, whereby heat absorbed by the solar energy absorbing element is transferred to the fluid. A trough is provided for receiving the flow of heated fluid along the base. The solar energy absorbing element lower valleys are positioned sufficiently close to the base such that the lower valleys are maintained in contact with the film of fluid flowing along the base, thereby further improving the heat transfer efficiency of the disclosed solar energy collector. The fluid supply conduits are provided with incrementally larger internal dimensions in a direction away from the trough for providing an incrementally increased flow of fluid over the solar energy absorbing element in a direction away from the trough, whereby fluid which must travel a greater distance to the trough will be provided in larger quantity.
