基于飞行马赫数和高度控制的逆升压电子设备冷却系统

Reverse-bootstrap Air Cooling System Control Based on Flying Altitude and Mach Number

该文介绍了国内最具有代表性的机载电子设备冷却系统的 2种形式 ,即冲压空气冷却系统和逆升压冷却系统。冲压空气冷却系统适用飞机低速飞行时的机载电子设备冷却 ,逆升压冷却系统适用飞机高速飞行时的机载电子设备冷却。当前逆升压系统温度控制采用 3点温度控制方法 ,该系统温度控制方法从冲压空气冷却方式转为逆升压冷却方式时 ,存在明显的缺陷 ,针对这一缺陷 ,该文提出了基于基于飞行速度和高度的逆升电子设备冷却系统的控制方案。

Reverse bootstrap air cooling system for electronic components has two cooling modes,the low ram air speed cooling mode and the high ram air speed cooling mode. In recent years, the control of reverse bootstrap air cooling system is mainly based on the temperature at three points, but this control system has defects.In this paper, the defects are pointed out and a new control method based on flying altitude and Mach number is also presented.
