摘要
随着机载机箱内部的热密度越来越高以及安装空间的有限性,对机箱的散热性能和外形尺寸也提出了更高的要求。首先分析了强迫风冷的散热方式,其次运用Flotherm软件对液冷机箱的散热性能进行了仿真验证,结果表明液冷机箱能更好地满足高热流密度的散热要求和结构外形要求。
With heat density inside the airborne cabinet rapidly improves higher and higher, and considering the limited instal-lation space, we propose higher request to the heat dissipation and the boundary dimension of cabinet. In this paper, we firstly introduce the heat dissipation pattern of forced-air cooling, and then use the software FLOTHERM to conduct simulation veri-fication on the heat dissipation performance of the liquid-cooled chassis. The results show that liquid-cooled chassis can bet-ter satisfies requirements on aspects of the heat dissipation and the structure appearance of high heating flux density.
