Abstract
A heat-pipe type solar collector includes a heat absorber portion adapted to absorb solar energy to evaporate a working fluid in heat tube elements; and a heat release portion communicating with the heat absorber portion and having a body of a semi-annular or annular cross-section. In the daytime, the vaporized working fluid exchanges heat with objects adjacent to the heat release portion. At night when temperature drops, the working fluid flows to the heat absorber portion to allow the body of the heat release portion to generate a vacuum for heat insulating purposes, thereby maintaining the temperature in the water reservoir.
