摘　　要：微小通道液冷技术作为一种新型高效热控技术,利用流动与传热的微尺度效应,可以极大地提高内部流动的对流换热能力。采用冷板流道内嵌矩形微小型肋片群形成微小通道液冷流道结构,针对不同肋片参数的微小通道液冷冷板散热性能进行分析,并针对流道结构进行优化分析,分析表明,微小通道液冷冷板极限散热能力随着肋片尺寸的下降而提高,典型微小通道冷板散热能力达到常规蛇形通道冷板的4倍以上,并成功应用于某型数字阵列模块冷却,效果良好。As a new effective thermal control technology,the micro/mini-channel liquid cooling technol-ogy can significantly improve the convective heat transfer capacity because of the micro-size effects of flow and heat transfer.A micro/mini-channel liquid cooling plate is made by adding rectangular fins to the flow channel of a cooling plate in this paper.The analysis and optimization of the cooling performance of the mi-cro/mini-channel cooling plate with different fin parameters and flow channels are made.The results show that the maximum heat transportation capacity of the micro/mini-channel cooling plate increases as the de-crease of the size of fins and it is 300% higher than that of the conventional snake-shaped channel cooling plate.The micro/mini-channel cooling plate has been used to cool a digital array module successfully.
