| 摘 要： | 微通道液冷板在高功率密度元器件散热上广泛使用,对板面温度均匀性提出了更加严格的要求。本文以提升液冷板板面温度均匀性为目的,设计了一个同侧单进口、出口的全铝材质的微通道液冷板,在热流密度为300 W的情况下,测试其使用单相水和相变工质冷却的板面温度最大温差分别为2℃以内和2.6℃(R236fa)。为了进一步提升温度均匀性,在初步流道设计方案的基础上提出单进口多出口的流道优化设计方案,并从仿真和实验两方面验证了优化方案的有效性,实现了使用R236fa工质相变冷却后板面温度最大温差可以控制在2℃以内。

| Abstract: | Fluid cooling plates are widely used in the heat dissipation of high-density components,which imposes stricter requirements for the temperature uniformity of the plate surface.In this study,to improve the temperature uniformity of the liquid-cooled plate,a liquid-cooled plate with a single inlet and single outlet was designed.Under a load of 300 W,the maximum temperature difference of the plate cooled by a single-phase water and multiple-phase-change working medium were evaluated to be within 2℃and 2.6℃(R236fa),respectively.To further improve the temperature uniformity,a scheme of a single inlet and multiple outlets for optimizing the flow channel was proposed on the basis of the preliminary flow channel design scheme.The effectiveness of the optimization scheme was verified by a simulation and experiment.The maximum temperature difference of the plate surface cooling with the R236fa working medium can be controlled to be within 2℃after the optimization. |
