摘要
为了在高发热功率条件下得到更好的相控阵雷达发射/接收(Transmitter/Receiver,T/R)组件温度一致性,设计了一种反向并行流道液冷冷板。基于Icepak热仿真分析软件对反向并行流道冷板与S型、分支型流道冷板进行了散热效能仿真,然后以阵面温度和温度分布标准差为指标对三种冷板进行了对比。结果表明:反向并行流道冷板换热降温效果好,且温度一致性最佳。为相控阵雷达冷板的均温性设计提供了参考。
In order to get better temperature uniformity for phased array radar transmitter/receiver(T/R)module with high calorific power,a liquid cooling plate with opposite-parallel flow channel is designed.Thermal simulation for S-channel,tree-channel and opposite-parallel channel cooling plate is carried out based on Icepak software.The antenna array temperature and standard deviation of temperature distribution among three types of cooling plate is compared.The results show that the opposite-parallel flow channel cooling plate has best performance of cooling and temperature uniformity.It provides guidance for the temperature uniformity design of liquid cooling plate flow channel for phased array radar.
