摘　　要：针对现有液体喷射冲击冷却研究存在的不足,设计了一种新型阵列喷射冲击间接液体冷却冷板,并对冷板进行了一系列实验。实验结果表明,冷板总热阻随着喷射速度增大而减小,但减小的趋势逐渐变缓,冷板进出口压差随着喷射速度的增大而升高,升高的速度逐渐加快;冷板总热阻随着喷射孔径的增大而增大,进出口压差随着喷射孔径的增大而减小,相对较优的喷射孔径为Φ0.5mm和Φ0.6mm。实验结果还显示喷射冷板的热阻明显小于普通冷板,这说明喷射冷板的冷却性能要优于普通冷板。There are some shortcomings in the research on liquid jet impingement cooling, so it designed a a new type of indirect liquid cooling cold plate with array jet impingement and did a series of experiments on the cold plate. Experimental results show that the total thermal resistance of cold plate decreases with the increase of jet speed, but the decreasing trend gradually slows down. The pressure drop of cold plate increases with the increase of the jet speed, and the increased speed gradually accelerates. The total thermal resistance of cold plate increases with the increase of jet aperture, and the pressure drop decreases with increase of jet aperture. The relatively better jet apertures are φ5mm and φ6mm. Experimental results also show that the total thermal resistance of the jet cold plate is much smaller than that of the general cold plate. It shows that the jet cold plate has higher cooling pe^ormance than the general cold plate.
