基于主动式两相回路的相变蓄热复合热控性能研究
|
摘要
本文针对短时或周期脉冲式工作设备,提出并搭建了一种以主动式两相回路与相变蓄热复合系统,并对其进行试验研究和分析。结果表明,优选R32作为主动式两相回路的流体工质,蓄热过程中,相变材料可有效地缓解模拟热源温升,而主动式两相回路的加入,能有效延长系统运行时间,在热流密度为53.8 W/cm~2时,复合系统可以将模拟热源温度维持在100℃内运行500 s;释热过程中,该复合系统可高效快速的恢复相变材料状态。
In order to protect short-term or impulse working equipment,a hybrid system combining phase change heat storage and active two phase cooling system was proposed.The results show that R32 is selected as the optimal working medium for the active two phase loop.The hybrid system can effectively extend the operation time of heat sink,and the heat sink temperature can be controlled within 100℃and operated 100s when the heat flux is 53.8 W/cm~2.The hybrid system can also rapidly recover the phase change material in the heat release process.
