摘　　要：针对某弹载相控阵天线的热设计难题，提出一种全新的由热管与相交材料联合进行热管理的方案，并设计了热管PCM热控装置。建立了采用该型热控装置的相控阵天线数学模型，对其热控过程进行了数值模拟，随后对热控装置的性能进行了试验测试，测得热源安装面最高温度为124．5℃。将测试结果与模拟结果进行对比，结果相吻合，两者最大偏差不超过15％，热管PCM热控装置可以解决天线的热设计难题。最后对该熟控装置进行了改进，改进后储热器内PCM温度梯度有效降低，热源安装面最高温度降低了6．7℃。研究表明，作为弹载热控领域的新方向，热管PCM联合热控的方案合理可行，可应用于实际工程问题。A fully new thermal control scheme composed of heat pipe and PCM was proposed to solve the phased array antenna＇s thermal design problem and the heat pipe/PCM composite thermal control device was designed. The numerical study was done by building the mathematic model of the antenna, and the experimental test was conducted from which the highest temperature of 124.5 ℃ on heat t source s mounting surface was obtained. The numerical results agree well with the experimental results, and the deviation between them is limited to 15%. Finally, the device was improved and the experimental test shows that the temperature gradient in PCM is effectively decreased in which the highest temperature on source＇s mounting surface is reduced by 6.7 ℃. This research shows that the heat pipe/PCM thermal control scheme is reasonable and feasible and the designed device can be applied in practical engineering applications.
