Optimum design and experimental study of small parabolic trough solar receiversmall trough type solar collector
摘要
Abstract
According to the principle of high performance and low cost,a small 1 trough type solar collector small parabolic trough solar receiverwas designed and madedeveloped for market,which collecting sunlight area is 12 m2.Its the main optimization points including:① The free backplane design reduces the trough reflector structuretheweight and materialsof the trough reflector structureand improve the precisionthe reflector surface accuracy.②The push rod linkage mechanism of push rod linkagereduces thenumber ofdriving devices.③ The separation type structure of reflector panel plays a self-cleaning function and reduces the intensity of manual cleaning.④The closed loop feedback technology is applied to the solar tracking control systemso that it can work all year.When solar radiation intensity is 540～660 W/m2,the experiment results show:circulating water can be heated to more than 170 degrees and the heat collecting efficiency is up to 0.52,but decreases with temperature of water increasing.关键词
