摘　　要：根据电子器件的高热流密度散热需求,设计了阵列式射流与微小通道热沉相结合的闭环回路冷却系统,并进行流动及换热性能测试.通过实验探索了系统运行工况参数如流量、背压、工质除气和入口过冷度对冷却性能的影响;比较了不同结构尺寸参数(射流孔形状、射流孔直径d、射流高度H)下热沉换热及流动性能的差异.实验数据与现有文献中经验关系式的预测结果相符.A liquid cooling loop system with micro-jet arrays and micro/mini-channels was designed for high-heat-flux cooling applications. Flow boiling experiments under different operation conditions were conducted to study flow and heat transfer performance of the heat sink. The effects of micro-jet geometry such as shape, diameter and height of jet hole are analyzed. Good agreement between the experimental data and the predictions has been found.
