摘　　要：为提高太阳能烟囱发电系统的发电量和发电效率,对系统中集热器热性能的影响因素进行了实验研究。简要介绍了太阳能烟囱集热器试验装置的建立,然后进行了大量实验得出了各个影响因素对集热器热性能的影响趋势,并分析了其产生变化的原因,从而对集热器性能的影响因素有了更为全面的认识,为太阳能烟囱发电站的建立提供了依据。Solar collector is one of the essential parts of solar chimney power plant system. In order to improve system output and efficiency, experimental researches on influencing factors of solar collector performance were done in the paper. System configuration of the experimental apparatus was briefly presented at first ; then, the changing trends of the collector performance under the effect of many influencing factors were achieved; and the reasons for the changes were also analyzed. The research results are useful for the establishment of solar chimney power plant system.
