The two water diversion plates are of symmetrical structures about the horizontal plane, and the two water diversion plates are provided with zigzag water diversion structures, so that the water separation efficiency of the water separation structures can reach more than 90%, the gas after water separation enters the cold side inlet cavity 15 of the heat regenerator and then enters the heat regenerator core 5 for heat exchange, the heat exchange is carried out, the gas after heat exchange passes through the cold side sealing head 3 of the heat regenerator and then is discharged from the cold side outlet 4 of the heat regenerator and then returns to the turbine for expansion and cooling, the cooled gas enters the cold side inlet 9 of the condenser and then enters the condenser core 8 for heat exchange with the hot side gas of the condenser, and finally is discharged from the cold side outlet 13 of the condenser to provide cool air for an aircraft, and therefore, the air refrigeration cycle is realized after water removal without separate addition of the water separator.
