摘　　要：将热管技术集成到反应器中,开发了一种太阳能高温热化学耦合相变反应器(STPCR)。该反应器的核心部件为由热板和多根热管耦合而成的高温异型热管(HTSSHP)。针对反应器实际运行时的特点,初步考察了高温异型热管在不同起始温度和倾角下的启动性能。实验结果表明,起始温度的变化对启动性能的影响可以忽略;0°、15°、30°和45°倾角下高温异型热均能成功启动,但热板段和热管段呈现不同的规律,热板段垂直放置时启动性能最好,而热管段15°倾角下最佳。证明了高温异型管结构合理,可应用于太阳能系统中。A solar thermochemical coupling phase change reactor （STPCR） integrated with heat pipe technology was presented.The core part of the reactor was a high temperatures special-shaped heat pipe （HTSSHP） which was composed of a flat heat pipe in disk-shape and multiple cylindrical heat pipes.The start-up characteristics of HTSSHP prototype was primarily tested at different initial temperatures and various inclination angles. Results showed that the influence of initial temperature on the start-up characteristics could be almost neglected.The HTSSHP could be started up successfully at the inclination angles of 0.,15.,3 0.and 4 5＇ I n addition, the inclination angle had different effects on flat heat pipe section and cylindrical heat pipe section of HTSSHP.The best inclination angle for the flat heat pipe section was 0., and 15.for cylindrical heat pipe section.The feasibility of operating HTSSHP under solar conditions was proven and the advantages of its special structure was confirmed.
