摘　　要：介绍了一套双蒸发器低温回路热管样机的运行特性,包括次蒸发器辅助热管的降温启动性能和系统的传热能力。样机以乙烷作为工质,能够在次蒸发器上施加一定加热功率的情况下更快、更顺利地进入稳定工作状态。实验结果表明,该样机最高能够传递16 W的热量,最低传热热阻为1.3 K/W。Working characteristics of a prototype double-evaporator cryogenic loop heat pipe （DeCLHP） are introduced in- cluding the cool-down and start-up process with the help of secondary evaporator and the heat transfer capacity. Using eth- ane as the working fluid, DeCLHP can achieve steady-state working status faster and smoother by implementing a heating power on the secondary evaporator. The experimental results show that the maximum heat transfer capability of DeCLHP is 16W with the minimum thermal resistance of 1.3 K/W.
