ABSTRACT:
A closed loop solar collector system includes a linear concentrating parabolic reflector, a linear vaporizer tube horizontally aligned along the focal line of the parabolic reflector, and a fluid metering assembly attached to the input end of the vaporizer tube for precisely metering a quantity of a vaporizable heat transfer fluid from a supply tank to the vaporizer tube. Solar energy concentrated by the parabolic reflector on the vaporizer tube vaporizes the heat transfer fluid. The heated vapor flows out the outlet end of the tube opposite the fluid metering assembly through a pipe and enters a heat exchanger. The heat exchanger contains a heat absorptive medium which absorbs heat from the vaporized fluid to cause the fluid to condense and release its latent heat of vaporization to the heat absorptive medium. The condensed fluid flows back to the heat storage tank for re-use under pressure provided by the vaporized fluid entering the heat exchanger. The heat exchangers are modular and a plurality of them can be interconnected to provide a desired amount of heat storage capacity. The heat stored by the heat exchangers can be used, for example, to heat air or water for domestic space or hot water heating systems, to power the vaporization cycle of an air conditioning unit, or to power a thermoelectric generator.
