某相控阵雷达天线阵面的热设计与验证

为了解决某高热流密度相控阵雷达天线阵面的散热问题，文中采用强迫通风冷却的散热方式，在天线阵面热设计中使用了高效换热的风–风换热器和高导热热管，满足了天线阵面组件壳体温度要求。同时，在设计天线阵面流场时，采用了内外风道隔离、内循环风道风机并联的送风方式，满足了天线阵面组件壳体的均温性要求。最后通过数值仿真和搭建平台测试两种方法，验证了该热设计方案的可行性。

Thermal Design and Verification of Antenna Array of a Phased Array Radar

In order to solve the problem of heat dissipation of a high heat flux phased array radar antenna, forced ventilation cooling, high efficiency air to air heat exchanger and high heat conductivity heat pipes are used in the antenna thermal design, which satisfies the shell temperature requirements of the antenna array components. At the same time, when designing antenna array flow field, the internal and external airways are isolated and the inner circulating airway fans are sealed in parallel, which satisfies the shell temperature uniformity requirements of the antenna array components. Finally, the feasibility of the thermal design scheme is verified by the numerical simulation and the tower platform test.
