摘　　要：针对相控阵雷达发射/接收组件冷却存在的问题,基于k-ε方程建立了热管换热的物理模型,采用有限容积法对发射/接收组件进行了热管冷却的数值仿真研究,通过实验测试了热管导热系数和热管对组件的冷却效果,研究了热管导热系数的变化规律及其对发射/接收组件冷却的影响,仿真与实验结果表明组件功率为63.8 W时热管可以将壳温控制在70℃左右,实验测试对仿真进行了验证,其最大相对误差为8.72%,研究表明热管应用于某型舰船雷达发射/接收组件冷却是有效的.According to the cooling problem of Radar T/R subassembly, a physics model of heat pipe heatexchanger is established based on K-ε equation. The simulation for T/R subassembly cooling using heat pipe is researched adopting of limited capacity method. The variety rule of heat pipe＇s heat-exchange rate and its influence to T/R subassembly cooling are experienced. The result indicates that the temperature of binding layer will be controlled at 70 ℃ or so by heat pipe cooling when the power of T/R subassembly is 63.8 W. The result of simulation is verificated by the experiment, which relative tolerance is 8.72 %. Research results show that cooling system of heat pipe is available to cool Radar T/R subassembly .
