摘要：

为了增强对喷射冷板散热性能影响因素的了解，通过实验研究了喷射距离对喷射冷板散热性能与阻力值的影响，并对喷射冷板散热性能的均匀性进行了分析。实验结果表明，在流量相同的情况下，现有结构喷射冷板的总热阻随喷射距离的增大先减小后增大，在喷射距离为1.5 mm时存在一个最小值；喷射冷板的阻力值随喷射距离的增大而降低，但喷射距离对喷射冷板的阻力影响较小；喷射冷板在水流方向的散热性能存在一定不均匀性，喷射冷板进水侧散热能力要略高于出水侧。

Abstract:

In order to enhance the understanding of influential factors that affect the thermal performance of the jet cold plate,the effects of the jet distance on thermal performance and resistance of the jet cooling plate are studied through experiments, and the uniformity of the thermal performance of the jet cooling plate is analyzed. Experimental results show that:(1) in the case of the same flow rate, as the jet distance increases, the total thermal resistance of the jet cooling plate in the existing structure increases too after it decreases firstly,and there is a minimum value when the jet distance is 1.5 mm;(2) the resistance value of the jet cooling plate decreases when the jet distance increases,but the effect of the jet distance is small;(3) there exists a certain unevenness of the thermal performance of the jet cooling plate in the direction of flow,and the cooling capacity in the inlet side is slightly higher than that in the outlet side.
