摘要： 毛细抽吸两相流体回路(CPL,CapillaryPumpedLoop)在运行过程中可能会发生蒸发器失效的现象,严重影响了其可靠性。文章对CPL在变工况过程中可能引起蒸发器失效的一些因素进行了分析,并通过实验研究了一个多回路耦合CPL系统在某些热边界条件发生骤变时,系统的瞬态响应以及部分蒸发器失效的过程。

Abstract: Evaporator maybe deprimes when a Capillary Pumped Loop (CPL) is operating, which affects its reliability greatly. Deprime of evaporator may result from many factors which are analyzed in this paper. Moreover, a multiple loop coupling CPL experiment system is developed and tests are conducted to observe transient responses and deprime procedures of the system when some thermal boundary conditions change.
