摘　　要：目的研究板式-导热油热沉中,导热油入口流速、热沉夹层厚度以及板材焊点矩阵间距对热沉温度均匀性和进出口压损的影响。方法通过理论计算、借助CAE仿真软件,设计单因素仿真试验,对热沉表面温度均匀性以及进出口压损进行分析,根据单因素仿真试验结果确认最优参数。结果在寻求热沉表面温差不大于1.55 K,且压损尽量小的过程中,能够达到该热沉最优性能的参数组合为导热油入口流速2 m/s、夹层厚度8mm、板材焊点矩阵间距60mm。根据仿真结果制作实物热沉并测试,测试显示热沉表面温差为1.28K,仿真值与其之间的误差为4.13%;压力损失为22943.7Pa,仿真值与其之间的误差为4.05%。结论该模型仿真结果与实测之间的误差在5%以内,说明仿真模型可靠,可以作为板式-导热油热沉的设计依据。The work aims to study the effects of inlet flow rate of heat transfer oil,thickness of heat sink interlayer and matrix spacing of plate solder joints on temperature uniformity and pressure loss of heat sink.Through theoretical calculation and CAE simulation software,a single factor simulation test was designed to analyze the temperature uniformity of the heat sink surface and the pressure loss of the inlet and outlet.The optimal parameters were confirmed according to the results of the single factor simulation test.In the process of seeking the surface temperature difference of a heat sink not more than 1.55 K and a pressure loss as small as possible,the parameter combination that could achieve the optimal performance of the heat sink was:the inlet flow rate of the heat transfer oil was 2 m/s,the thickness of the interlayer was 8 mm,and the spacing of the plate solder joint matrix was 60 mm.According to the simulation results,the physical heat sink was made and tested.The test showed that the surface temperature difference of the heat sink was 1.28 K,and its error with the simulation value was 4.13%.The pressure loss was 22943.7 Pa,and its error with the simulation value was 4.05%.The error between the simulation results and the measured results is less than 5%,which indicates that the simulation model is reliable and can be used as a design basis of plate-heat transfer oil heat sink.
