摘　　要：T/R组件内功率器件的散热对有源相控阵雷达的性能和可靠性有重要影响。本文针对T/R组件体积小、内部热流密度大的特点,采用强迫液冷的冷却方式,设计了液冷式冷板,并采用热仿真软件Icepak对其进行了热仿真。通过优化设计,可以将主要功率器件的壳温降至90℃以下,满足其可靠工作的温度要求。Heat dissipation of power device in T/R module has important effect on performance and reliability of active phased array radar. Aiming at characteristics like small volume and massive internal heat flux density of T/R modules,liquid cooling cold plate is designed by using forced liquid cooling; and its thermal simulation is performed by using thermal simulation software. The shell temperature of main power devices can be reduced to below90℃ by optimizing design,and this can meet temperature requirement for reliable operation.
