微/小通道冷板在某型相控阵天线上的对比分析

微通道换热是近年来电子机械工程抗恶劣环境研究的热点之一。由于其具有良好的换热特性,现在逐渐被应用于高热流密度电子设备的冷却散热系统设计之中。相控阵天线具有热源集中、热流密度极高等特点。文中将新型微通道冷板与某型相控阵天线进行有机结合,提出了一种新的相控阵天线冷却方式。同时,通过基于有限体积法的仿真分析表明,微通道冷板相较于小通道冷板更有利于控制天线中T/R模块的温度。

Comparison Analysis of Micro/Mini-Channel Cold Plate on a Phased Array Antenna

Heat convection in micro-channel is one of the focused research points in the field of anti-adverse environment in electro-mechanical engineering. Micro-channel heat convection is gradually applied to cooling systems of high heat flux electronic equipment because of its good heat transfer property. Phased array antenna has the characteristics of concentrated heat source and extremely high heat flux. A new type of micro-channel cold plate and a type of phased array antenna are organically integrated, and a new cooling method for phased array antenna is presented. Meanwhile, according to the numerical simulation based on finite volume method （FVM）, micro-channel cold plates are more advantageous than mini-channel cold plates for controlling the temperature of T/R modules in antenna.
