Abstract:Based on the advantages of the Parabolic Though Concentrator ( PTC) and the heat p ipe evacuated tubular
collector, a kind of heat p ipe evacuated tubular collector used for the solar parabolic through power generation system
was developed. The structure design of the concentrator and the receiver of the new collector is p resented. According
to the energy conversation equation and characteristics of the concentrator, the collector′s efficiency was calculated,
showing that it is higher than that of most foreign collectors.
Key words: solar parabolic through power generation system; heat p ipe; heat collector
