Flow boiling heat transfer performance in phase separation structure countercurrent microchannel under the action of pin electrodes
为研究针状电极与相分离结构强化技术组合作用下微细通道流动沸腾传热性能,该研究提出了一种平行逆流微细通道热沉,针对顺流和逆流微细通道,通过高低压切换实现气相分离.以乙醇为试验工质,改性聚偏二氟乙烯多孔疏液膜(polyvinylidene fluoride,PVDF)作为气液相分离工具,在入口过冷度为10 ℃,有效热流密度范围为48.08～87.29 kW/m2工况下开展流动沸腾试验,引入饱和沸腾传热系数传热强化因子(Fht)研究不同相分离结构孔数(…查看全部>>
The purpose of this study is to explore the boiling heat transfer performance of microchannel flow under the combination of two enhanced technologies of pin electrodes and phase separation structure.Therefore,a parallel bidirectional microchannel heat sink was proposed to realize the gas-phase separation by switching high and low pressure for the downstream and countercurrent microchannels.Ethanol was taken as an experimental working fluid,while the modified…查看全部>>
