摘　　要：基于呼和浩特地区高寒气候条件,搭建两组完全一致的平板热管式太阳能集热系统,通过实验对比分析太阳辐射强度、传热工质流量、集热板表面积尘等因素对集热器瞬时集热效率以及系统热性能的影响。结果表明,在同等外界条件下,集热器的集热效率随着工质流量的增加而增大,集热效率与太阳辐射强度变化趋势相近,随积尘密度的增加,集热板表面积尘导致系统的得热量减少,集热性能下降。Based on the cold and high-latitude climate conditions of Hohhot region,two identical flat-plate heat pipe solar collector systems were constructed,and the effects of solar radiation intensity,heat transfer medium flow rate,collector panel surface dust accumulation and other factors on the instantaneous thermal efficiency of the collectors as well as the thermal performance of the system were compared and analyzed through experiments.The results show that,under the same external conditions,the thermal efficiency of the collector increases with the increase of working fluid flow.The change trend of thermal efficiency is similar to that of solar radiation intensity.With the increase of dust density,the dust accumulation on the surface of the collector plate leads to the decrease of the heat gain of the system and the decrease of the collector performance.
