An airborne motor cooling system with liquid ammonia as a medium comprises a cooling air supply port, a liquid ammonia high-pressure storage tank, a first stop valve, a temperature adjusting valve, an expansion valve, a flow meter, a flow divider, a temperature sensor, a generator controller, a generator, a driving motor controller, a driving motor, a second stop valve, a pump and a DSC battery. Liquid ammonia with large latent heat of vaporization is used as a motor cooling medium in the takeoff stage of an aircraft, motor cooling is achieved through high-speed convection of the aircraft and air after takeoff, meanwhile, the ECU is arranged, the cooling effect is met, the ammonia consumption is reduced, second-layer protection is provided during air cooling, finally, high-temperature ammonia subjected to sufficient heat exchange is guided into a DSC battery, and the service life of the DSC battery is prolonged. And hydrogen generated by thermal decomposition of the ammonia gas participates in electrochemical reaction and generates electric energy. The working environment of the aircraft motor is greatly improved, the maximum power running time of the motor is prolonged, meanwhile, chemical energy of waste ammonia gas is recycled, and better safety, stability and economical efficiency are achieved.

    以液氨为介质的机载电机冷却系统,包括冷却空气供应口、液氨高压储罐、第一截止阀、温度调节阀、膨胀阀、流量计、分流器、温度传感器、发电机控制器、发电机、驱动电机控制器、驱动电机、第二截止阀、泵、DSC电池;在飞机起飞阶段使用汽化潜热大的液氨作为电机冷却介质,起飞后利用飞机与空气的高速对流实现电机冷却,同时设有ECU电子控制单元,满足冷却效果的同时节省氨气用量,并在风冷时提供第二层保护,最后将充分换热的高温氨气导入DSC电池,氨气热分解产生的氢气参加电化学反应并产生电能。极大改善了飞机电机的工作环境,延长电机最大功率的运转时间,同时实现了对废弃氨气的化学能再利用,达到了更好的安全性,稳定性与经济性。
