随着航空工业发展飞机飞行速度不断提高,电子设备也不断增加,机上系统设备发热量剧增,飞机的环控系统也愈加被人们所重视,在环控系统Ecu制冷组件中的空气散热器冷边,只要采用冲压空气冷却的飞机在地面停机或低速飞行时,其空气散热器冷边缺乏冷却空气,使系统无法正常工作,特别炎热夏天,座舱温度就急剧上升,使乘员难以忍受。这是历年来飞机无法解决的难题。 With the continuous development of the aviation industry, the flight speed of the aircraft is continuously increasing, and the electronic equipment is also increasing. The heat of the on-board system is increasing. The air-condition control system of the aircraft is also paid more and more attention. In the air-conditioning system of the Ecu refrigeration system As long as the use of razor-cooled aircraft on the ground down or low-speed flight, the lack of cooling air radiator cold edge, the system does not work, especially hot summer, the cabin temperature rose sharply, so that the crew unbearable. This is a problem that the aircraft can not solve over the years.
