探索减小航空设备柜散热系统通道压降的方法

摘要

The biomimetic drag-reducing surface is proposed to be applied in the ventilation system of avionics equipment cabinet, according to the actual situation, the size of micro-grooved surface is designed, and numerical simulation of fluid field is carried out thoroughly and comprehensively in Fluent software, the results show that the pressure loss of ventilation system can be reduced by more than 8%. The application of biomimetic drag-reducing technology in avionics equipment cabinet has opened up new roads which has the important significance.%　　将仿生减阻技术应用到航空设备柜的散热系统中，根据实际工作状态对仿生减阻表面进行设计，并在Fluent 软件中进行仿真分析，结果表明采用沟槽减阻表面后散热系统的压力损失可以降低8%以上。仿生减阻技术为航空设备柜散热系统的设计提供了新的思路和途径，具有重要的意义。
