ABSTRACT:
This invention provides for an unusually efficient, lightweight, economical and durable solar collector employing a fibrous absorber in an evacuated-tube type solar collector. The depth of the absorber, measured in centimeters more efficiently traps radiation than the shallow depth of a plate absorber surface. The fibers are arranged in irregular order with space for a fluid. Sufficient fiber mass is used to blanket all radiation. The absorber is disposed inside the inner tube of a two tube collector. The second tube fits about the inner tube in a manner that allows the space between the walls of the tubes to be evacuated of air. A reflector may be disposed inside the lower half of the outer tube to improve efficiency. A fluid enters one end of the collector and passes via ducts through the absorber conducting heat from the highly radiation absorptive fibers and exits the other end. The fiber may be compressed to opacity and a tube fitted within the ducts for the heating of another fluid in the tube.
