摘要

以热管和环路式热管为主要形式的两相流冷却技术凭借其良好的冷却能力和较低能耗的特点在空间冷却中已经有了多年的实验研究和太空飞行记录。随着热源发热量增加、热流密度的增大以及散热回路日趋复杂，用机械泵为驱动力的两相冷却系统逐渐引起各国热控科研人员的重视。通过对机械泵驱动的两相流冷却技术同毛细力驱动的环路式热管及机械泵驱动单相冷却技术的工作原理和主要的性能进行分析比较，可以看出该系统切实可行，并且在启动，散热能力和结构设计上有明显优势。以CO2为循环工质对该新型系统的散热特性进行试验研究，结果证明机械泵驱动的环路式热管系统具有低能耗、高控温精度和结构紧凑的特点。

Abstract

A brief review of two-phase cooling applications was presented.The differences between MPLHP(Mechanical Pumped Loop Heat Pipe) and LHP/CPL(Loop Heat Pipe /Capillary Pumped Loop)or Mechanical Pumped Single-phase Cooling Loop were discussed according to working mechanism and heat transfer characters.The characters of MPLHP system using CO2 as a working fluid were investigated theoretically and experimentally.The results show that the loop heat pipe driven by a mechanical pump has obvious advantages

such as lower power consumption

higher control accuracy

and compactness.
