摘要

两相热虹吸回路由于其较高的散热性能在高功率电子设备冷却领域有较好应用前景。为了解决四通道数字阵列模块的冷却问题，本文设计了一个两相闭式热虹吸回路冷却系统样机并对系统启动特性、充液量和工作倾角对系统散热性能的影响进行了实验研究。研究结果表明，样机系统结构及散热性能满足指标要求，启动性能和工作性能良好。此外，该系统对热耗1600 W、局部热流密度接近100 W/cm2的组件的冷却效果良好。

Abstract

Two phase thermosyphon loop has a good potential of application in cooling of electronic equipment with high power source because of its relatively high efficiency of heat dissipation performance. To solve the cooling problem of a DAM with four channels

this paper designs a prototype of two phase closed thermosyphon cooling system. The starting characteristic of the system

the influence of the refrigerant charge and working inclination angle on its heat dissipation performance are investigated experimentally in this paper. The results show that the structure and heat dissipation performance of the system match the requirement. It also can be found that the starting characteristic and the working performance of the system are very good. In addition

a 1600W module with local heat flux near 100W/cm2 is cooled very well by the system in this paper.
