The invention provides an outer rotor liquid cooling motor and an aircraft. The outer rotor liquid cooling motor comprises a power module, a first heat dissipation module and a second heat dissipation module. The outer rotor liquid cooling motor is provided with a first channel and a second channel, the suction pump is used for sucking cooling liquid, the cooling liquid flows to the stator and the first channel through the liquid guide pipe, and the cooling liquid is used for absorbing heat of the stator; the air outlet communicates with the second channel and is used for forming cooling airflow, and the cooling airflow sequentially flows through the converter, the second channel and the air outlet and is used for cooling the cooling liquid. The first heat dissipation module and the second heat dissipation module are arranged in the outer rotor liquid cooling motor, a cooling liquid circulation system and a cooling gas circulation system are formed, the stator is cooled through cooling liquid, the cooling liquid is cooled through cooling air flow, meanwhile, the cooling air flow can further penetrate through the interior of the outer rotor liquid cooling motor, and the cooling effect is improved. Heat energy in the outer rotor liquid cooling motor is taken away, and the heat dissipation efficiency of the outer rotor liquid cooling motor is improved.
