摘 要:本文通过计算流体力学数值仿真和实验,研究了花形仿生拓扑在相控阵天线液冷系统中的传热特性。相控阵天线共有1个矩形发射终端,4个L形接收终端和12个矩形接收终端,为此设计了三种不同散热能力的液冷板,并分别组成花形仿生拓扑阵面和传统的全并联拓扑阵面。研究结果表明:在相同热环境和运行条件下,花形仿生拓扑阵面传热特性全面优于传统的全并联拓扑阵面,花形仿生拓扑阵面温度均匀性更好,不仅TR组件壳温均匀性优于±3℃,所有终端之间的最大温差也下降了8%~15%,证明花形仿生拓扑阵面是一种传热效率更高的热控方案。This study investigates the application of flower-shaped bionic topology in phased array antenna liquid cooling systems through computational fluid dynamics(CFD)simulations and experimental validation.The phased array antenna comprises a rectangular transmitting module,4 L-shaped receiving modules and 12 rectangular receiving modules.All these three types of liquid cooling plates are designed to form either a flower-shaped bionic topology or a fully parallel topology.Comparative analysis reveals that the flower-shaped bionic topology offers a highly efficient thermal control solution.The temperature gradient of the antenna employing flower-shaped bionic topology is significantly smaller than that of the fully parallel topology.The temperature difference between modules is controlled to±3℃,representing an 8%~15%improvement over the fully parallel topology.
