研制了复合结构毛细蒸发器环路热管，实验研究了环路热管的启动性能与运行特性，通过与单一结构毛细蒸发器环路热管对比，表明复合结构毛细蒸发器环路热管传热功率密度得到了提高，热阻明显降低。但在低功率下启动时，复合结构毛细蒸发器环路热管的温度波动现象加剧。

英文摘要：

A prototype of loop heat pipe with the composite capillary evaporator was developed to investigate the operational characteristics of the novel structure LHP. The thermal behaviors of the LHP corresponding to the start-up and variation of the heat load were experimentally studied. The thermal resistance and the temperature oscillation phenomena were also analyzed. The comparison of the operational characteristics between the composite capillary evaporator and single capillary evap- orator revealed that the LHP with composite capillary evaporator has higher heat transfer capability and smaller thermal resistance than those of conventional LHP with single structure capillary evapora- tor. But the temperature oscillation was intensified for the LHP with composite capillary evaporator during the start-up process at the small input heat load.
