摘要
针对相控阵雷达子阵系统不同的结构方案,应用热设计仿真软件建立了系列热仿真模型。依据冷板类型、冷板安装位置、功能层类型,将系列模型分为3组,并给出了3组模型的温度剖视图和温度全图。通过对热仿真结果的对比分析,选择了能较好满足子阵热设计总体要求的结构方案。分析总结了带液冷冷板子阵系统的散热规律,为今后高功率密度和大功率器件的散热提供参考。
In view of the different structure schemes on the array radar substructure , it establishes a series of sim-ulation models similar to the schemes in the application of the thermal simulation software CFD .On the basis of cold plate type , cold plate installation position and function layer type , it divides the series models into three groups , then obtains the simulation images of the three groups respectively .Through the comparison and analysis of thermal simulation results , it shows the structure scheme which better meets the general requirements of ther-mal design on substructure .It analyzes and summarizes the heat dissipation of substructure with cold plate , pro-vides the guidelines for the heat dissipation of high power density and high power devices .
