摘　　要：为提升国产某款水冷板(liquid-cooled plate,LCP)的传热特性,降低功耗,对其建立3D模型,通过实验进行数值模拟。考虑水冷板结构特性,提出放大系数、散热柱宽度、散热柱数量、流道高度和宽度等因素组成的结构参数,确认对应的16组正交试验改进方案,并获取对应数据;基于场协同原理,利用传热协同角β和压力协同角θ筛选出传热性能好、功耗低的方案,同原始方案进行综合性能对比。数值模拟与实验数据的吻合程度较好,最大误差为6.61%;改进方案10(improvement scheme 10,IS10)的平均传热协同角和压力协同角分别下降0.97%和1.04%。综合性能方面,IS10的最大差异为0.372%;优化后,水冷板出口温度高4.62~5.93℃,速度高0.1 m/s,压力损失降低161.89 Pa。To improve the heat transfer and power consumption of an LCP,we build a 3D model and verify its numerical simulation through our experiments.With the structural parameters(amplification factor,width of cooling column,number of cooling column,height and width of flow channel),the corresponding 16 groups of orthogonal test improvement schemes are examined.Based on the field coordination principle,Improvement Scheme 10 with better heat transfer and lower power consumption is selected by heat transfer coordination angleβand pressure coordination Angleθ,and compared with the original scheme.Finally,the numerical optimized scheme is employed to verify the improvement.Results show our numerical simulation is in line with the experimental data with a biggest error of 6.61%.The averageβandθof Improvement Scheme 10 are down by 0.97%and 1.04%respectively.In the overallγ,the largest difference of the two is 0.372%.After the optimizaiton,the outlet temperature of coolant increases by 4.62~5.93℃,the speed rises by 0.1 m/s and the pressure loss reduces by 161.89 Pa.
