The invention discloses an eVTOL aircraft lift electric drive cooling system which comprises a motor arm, the front end of the motor arm is connected with a motor arm front fairing, the lower portion of the motor arm front fairing is connected with a heat dissipation water tank, the rear end of the heat dissipation water tank is connected with a controller and a lift motor through a liquid cooling assembly, and the lift motor and the controller are installed in the motor arm. The appearance of the heat dissipation water tank and the motor arm are of a conformal structure, and the outer surface of the heat dissipation water tank is of a curved surface structure. The system adopts the radiator integrated with the motor arm structure, the radiator does not need to be arranged outside the aircraft structure, a cooling air duct does not need to be formed either, and the resistance of the aircraft is reduced. And the integrated heat dissipation water tank is cooled by external incoming flow, so that the cooling requirement of the aircraft is met at an acceptable cost.
