摘　　要：基于热管式平板型太阳集热器吸热板传热过程的特点以及换热器的传热有效度-传热单元数法,对热管式平板型太阳集热器的被加热流体出口温度及热效率进行理论分析和计算,并将结果与具有相同结构尺寸的热管式平板型太阳集热器的实验研究结果进行比较。结果表明,根据提出的理论分析方法所得到的结果与实验研究结果吻合较好,可用于分析和讨论相关参数对热管式平板型太阳集热器热性能的影响。为研究热管式平板型太阳集热器的热性能提供了一种新的理论方法。Considering the heat transfer characteristics of absorber plate of a heat pipe flat plate solar co conjunction with the method of heat transfer effectiveness-heat transfer units number for heat exchangers, llector in the theo- retical analysis and calculation of the heated fluid outlet temperature and the thermal efficiency for a heat pipe fiat plate solar collector has been carried out. The calculated results have been compared with the experimental results of a heat pipe fiat plate solar collector which has the same structure as the one used for calculations. The compari- sons showed that, the proposed theoretical method is agree very well with the experimental result, thus can be used to analyze and discuss the influence of relevant parameters on the thermal performance of heat pipe flat plate solar collector. This study provides a new theoretical method to investigate the thermal performance of heat pipe fiat plate solar collector.
