中文摘要：

从集热器结构、传热效率、工艺、优缺点等方面详细介绍了3种常见的热管平板式太阳能集热器,它们包括蜂窝热管平板式、真空玻璃盖板热管平板式、CPC热管平板式太阳能集热器。与普通热管平板式集热器相比,3种改良方式均可降低集热器热损失,有效提高集热效率。通过对不同种类热管平板式太阳能集热器的热管种类、工作温度、结构参数等分析,发现随着温度升高,集热器集热效率下降,以及热管蒸发段长度普遍大于冷凝段长度等现象。

英文摘要：

Three common heat pipe flat-plate solar collectors are introduced in details from the configuration of the collector such as heat transfer efficiency, crafts, merits, and so on, including the flat plate solar collector of honeycomb and heat pipe（HHCHP）, flat plate solar collector of vacuum glass-cover board and heat pipe（HVGHP） and a compound parabolic concentrator heat pipe type solar collector（CPC）. Compared with common heat pipe flat-plate solar collectors, these three improved programs can reduce heat loss, and effectively improve efficiency of the collector. From the analysis of different heat pipe types, operating temperature, structure parameters, a phenomenon is discovered that whatever which type of heat pipe flat-plate solar collector is, as temperature goes up, the efficiency of the collectors drops and the length of evaporation is longer than the length of condensation.
