中文摘要：

为了将太阳能中高温利用的槽式集热器（PTC）设备用于150~180℃中温蒸汽利用,并降低槽式太阳能集热器的成本,设计了一种新型集热管结构,并对其进行了传热模型的理论建模,将其在特定参数下的理论效率值与直通式真空管的效率实验值进行了对比,最后结合两种集热管的经济性进行比较。

英文摘要：

In order to use parabolic trough collector（PTC） which was used in the high-temperature solar thermal utility to generate steam between 150℃ and 180℃,and reduce the cost of PTC,a new kind structure of heat collector element（HCE） was designed,its heat transfer theoretical model was built,and its efficiency was calculated and compared with experimental data.At last,economy factors of the two kinds of HCE were compared.
