摘　　要：与传统液冷系统相比,两相流冷却系统在冷板流道多余物控制上,除了不能有金属切屑、油污等杂质外,还增加了除水要求,防止低温环境下水结冰堵塞流道。冷板流道布局复杂且存在盲区,除水难度极大。文中针对两相流冷板除水烘干工艺进行了重点研究,采用加热升温与抽真空相结合的工艺措施使冷板流道内的残留水持续沸腾汽化以达到除水目的,并通过理论研究与试验分析将工艺参数固化。试验结果表明,该工艺方法可行,且能有效提高产品两相流冷却系统的整体可靠性。Compared with traditional liquid cooling systems,two-phaseflow cooling systems not only prevent metal chips,oil stains and other impurities from remaining in the cold plateflow channel,but also add water removal requirements to prevent water from freezing and blocking theflow channel in low-temperature environments.The cold plateflow channel has complex layout and blind area,making it extremely difficult to remove water.In-depth research on the techniques of water removal is conducted in this paper.The residual water in the cold plateflow channel is continuously boiled and vaporized by heating and vacuumizing to reach the goal of water removal.The proper process parameters are determined by theoretical research and experimental analysis.Experiment results show that the techniques are feasible and can improve the overall reliability of the product cooling system effectively.
