Thermal Design Method of Missile Borne Radar Seeker

摘要:

针对雷达导引头不同使用工况,论述了雷达导引头主要的散热方式,包括被动散热和主动散热。被动散热包括结构件导热、相变材料储热以及热管导热等方式。主动散热包括风冷、液冷、压缩气体膨胀制冷、喷雾冷却等。通过综合分析,相变材料储热是目前雷达导引头散热的常用技术。未来制导舱空间越来越紧凑,热管加相变材料复合散热的应用有利于提高空间利用率。此外,喷雾冷却在高热流密度领域具有良好应用前景。

Abstract:

According to different working conditions of radar seeker, the main heatdissipation modes of radar seeker are discussed, which include passive heat dissipation andactive heat dissipation, Passive heat dissipation includes heat conduction of structuramembers, phase change materials thermal storage, heat conduction of heat pipe, etc, Activeheat dissipation includes air cooling, liquid cooling, compressed gas refrigeration, spraycooling, etc. Through comprehensive analysis, phase change materials thermal storage is acommon technology for heat dissipation of radar seeker. With the space of radar cabinbecoming more compact in the future, the application of heat pipe and phase change materiawill be conductive to improving the utilization rate of space, And spray cooling has a goodapplication prospect in the field of high heat flux.
