<p>The solar energy receiver comprises an insulating housing (2) to which is fixed a cooled reflector (4) which is circular in plan, a prism (6), a low temperature receiver (8) and a high temperature receiver (10). In front of the low temperature receiver (8) is a filter (12) which transmits most of the incident solar radiation, but not the majority of the longer wavelength solar radiation emitted from the receiver (8). In front of the high temperature receiver (10) is a filter (14) which operates in a similar manner to filter (12) by preventing the transmission of solar radiation having wavelengths corresponding to the majority of emitted radiation from the receiver (10). Lining the housing between the reflector and the receivers is a cooled stray radiation absorber (16). Cooling tubes (18), shown end on, carry a working fluid and are located between the housing (2) and the receivers (8, 10), the absorber (16) and reflector (4). On the bottom of the receiver assembly is aperture (20). A reflected radiation absorber (26) lies to one side of the cooled reflector.</p> |
