| 摘 要： | 利用环路热管换热技术对光子吸收器进行换热可以提高光子吸收器的换热效率、减小其结构尺寸，而且运行时无振动，是未来高性能加速器中设计光子吸收器的重要技术储备。分析环路热管在光子吸收器上应用时的传热性能，发现目前环路热管的换热能力完全满足光子吸收器的换热需求，但热沉的结构、特别是导热距离需要严格优化。利用航天五院C18型号环路热管，优化设计了一台环路热管式光子吸收器样机，数值模拟其运行时的温度分布，并实验测试了光子吸收器样机的总体换热能力。

| Abstract: | Loop heat pipe can be used on the photon absorber to improve its heat exchange efficiency and reduce its structural size, and for vibration-free operation, so it is an important technical reserve for the future design of photon absorbers in high-performance accelerators. The heat transfer performance is analyzed when the loop heat pipe is applied to the photon absorber, the results show that the current heat transfer capacity of the loop heat pipe fully suffice the requirements of the photon absorber, but the structure of the heat sink, especially the heat transfer distance, needs to be strictly optimized. Then, using the type “C18” loop heat pipe made by China Academy of Space Technology, a prototype of the photon absorber heat extracted by loop heat pipe was designed and optimized, the temperature distribution is simulated numerically, and the heat transfer capacity was tested experimentally. |
