摘要
民航飞机的设备冷却系统,用于驱散飞机上所有电子设备所发出的热量,使其在可靠的环境中工作。设备冷却系统的维护相当关键。波音767飞机的设备冷却系统可分为前设备冷却系统、后设备冷却系统和娱乐系统冷却系统。其中前设备冷却系统相对独立,各部件的工作状态随外界条件的变化而复杂多变;娱乐系统冷却系统则是依靠客舱空调系统提空冷气,为娱乐设备中心散热;后设备冷却系统与洗手间/厨房通风系统共用同一套冷却通风系统。由于三个子系统的工作原理不同,因此在日常维护中除需分清各部件所属的子系统外,弄清系统发生故障时的外界条件也尤为重要。
Civil aircraft equipment cooling system is used for all electronic equipment on the plane to disperse heat emitted. Equipment cooling system enables electronic devices to work in a secure environment. The maintenance of equipment cooling system is so critical. Boeing 767 aircraft equipment cooling system can be divided into foreword equipment cooling system, entertainment equipment cooling system and after equipment cooling system. Where the foreword equipment cooling system is relatively independent, working status of each component with complex changes in external conditions; entertainment equipment cooling system is to rely on empty air-conditioning system to mention, for the entertainment center cooling; after equipment cooling systems and toilet/kitchen ventilation systems share the same set of cooling ventilation system. Since the three subsystems works differently, so in addition to routine maintenance required to distinguish between the various components belong subsystem, the failure to understand the system of external conditions is particularly important.
