摘要
该文为解决相控阵天线阵面的温度不均,设计了S型微通道、类树形分叉横向微通道和T型纵向微通道3种拓扑结构。以多热源温度均匀性为设计指标,利用数值仿真分析了3种微通道拓扑结构的性能,结果表明T型纵向微通道冷板的热源温度均匀性最优。通过实验验证了T型纵向微通道结构的优越性,并且得出了多热源温度均匀性随着热源总功率的提高而降低,随入口流量的增加而提高的规律,为多热源相控阵天线的热设计提供了依据。
In order to solve the temperature non-uniformity on phased array antenna,three topology structures are designed,including:microchannel based on S type,horizontal micro-channel based on similar tree bifurcation,and longitudinal microchannel based on T type.Numerical simulation is carried on to study the temperature uniformity of three microchannel heat sinks with multiple sources.The results show that longitudinal microchannel based on T type has the best uniformity of temperature which is verified by the experiment,and the temperature uniformity is reduced as the total power goes up,yet improved with the increase of inlet flow rate.The study provides a useful reference for the thermal design of phased array antenna with multiple sources.
