摘　　要：采用新型导热介质,主要介绍了集热装置的热性能实验方法,并着重对槽式跟踪太阳能集热器集热性能进行了研究及分析,通过对槽式跟踪热管真空管集热器理论值与试验值的比较,结果表明:利用导热油强化传热技术并结合热管技术,使得槽式跟踪太阳能集热器具有较高的集热效率,可产压力2 MPa,温度达200℃以上的饱和蒸汽。The experiment of thermal property for a solar thermal collector with a new-type heat-conducting medium used is described.The heat-collecting efficiency of a trough-type sun-tracking solar thermal collector was investigated experimentally,and the results were compared with the theoretical results of a heat pipe/evacuated tube thermal collector of the same type.It was found that the trough-type sun-tracking solar thermal collector can get higher heat-collecting efficiency if introducing the conduction oil to enhance the heat transferability in combination with the heat pipe technology.In this way the saturation steam pressure can come up to 2MPa with the temperature above 200℃.
