摘要:
为克服液体冷却在相控阵雷达功放模块热管理中设备复杂,能耗大,稳定性差,管理难度大等缺点,分析提出了热管冷却的功放模块。根据热管性质和工作条件,对热管热作用过程进行合理的假设,建立了热管热平衡状态下的传热模型。应用有限元法对功放模块的热管冷却和液体冷却进行仿真分析,对相同条件下二者相应温度场和热流密度分布进行了比较分析。仿真分析结果表明,在相同条件下,热管冷却比液体冷却具有更好的热传导性和表面均温性,验证了热管冷却技术在功放模块应用中的可行性。
Abstract:
To overcome the shortcomings such as complex devices, great energy consumption, poor stability and management difficulty in heat management of active power divider of airborne phased array radar used liquid cooling medium, the active power divider cooling used heat pipe was put forward. According to machining properties of the heat pipe and working conditions, on the basis of the theory of thermal equilibrium of heat pipe, the mathematical model was established through reasonable hypothesis. Based on finite element method, simulations were performed for the distribution of temperature and heat flux of the active power divider cooling used heat pipe and liquid cooling medium separately. The distribution of temperature and heat flux of both were analyzed and compared in the same condition. The simulation results show that heat pipe has better thermal conductivity than liquid cooling medium, confirming the feasibility of the heat pipe method in active power divider application.
