Heat transfer path design and heat flow analysis of satellite phased array antenna

  • 摘要:

    为满足星载相控阵天线多热源、高功耗、大功率密度散热问题,设计了由外敷热管和预埋热管组成的十字交叉热管网络,将点热源转化为面热源,同时借助U型热管耦合+Z板与±Y板,强化蜂窝板间换热,通过有限元模型对整星进行热流分析,并进行试验验证。仿真结果表明:U型热管传导了32.9%的相控阵天线热耗,其中66.6%传导至处于阴影区的+Y板,33.4%传导至处于阳照区的−Y板。试验结果表明:整星在长时峰值工作模式下,热管自身温差小于1 ℃,相控阵天线温度满足接口要求。热管网络满足整星长时峰值工作散热能力需求,多次十字交叉热管网络得到验证,U型热管耦合+Z板和±Y板,解决了单个蜂窝板散热能力不足问题。
