摘要： This application provides a motor, a motor cooling system, and an electric vehicle. The motor includes a rotor, the rotor includes a rotor iron core, a first end cover, and a second end cover, and the first end cover and the second end cover are respectively connected to two ends of the rotor iron core. The first end cover is provided with a liquid inlet channel, the rotor iron core is provided with a liquid flow channel, and the first end cover or the second end cover is provided with a liquid outlet channel. The liquid inlet channel connects the liquid flow channel and space outside the rotor, the liquid outlet channel connects the liquid flow channel and the space outside the rotor, and an outlet of the liquid outlet channel faces a stator winding. The liquid inlet channel, the liquid flow channel, and the liquid outlet channel form a rotor channel for a coolant to flow through. Technical solutions of this application can reduce processing costs while ensuring heat dissipation reliability of the rotor of the motor.

摘要： This application provides a powertrain cooling system and method, a powertrain, and an electric vehicle, and relates to the field of electric vehicle technologies. The cooling system includes a cooling circuit and a cooling working substance. The cooling circuit includes a first cooling channel and a second cooling channel that are connected. The first cooling channel is configured to dissipate heat of an inverter of the electric vehicle. The second cooling channel is configured to dissipate heat of a motor of the electric vehicle. The cooling working substance is an insulating working substance, and the cooling working substance flows from the first cooling channel into the second cooling channel. The cooling system can improve an effect of dissipating heat of the powertrain.

摘要： The present disclosure relates to a cooling system, an electric motor and a wind-power electric generator set. The cooling system is applied to an electric motor; the electric motor includes a stator support and a rotor support; the stator support is dynamically sealingly connected to the rotor support to form a ventilation chamber arranged at an end of the electric motor in an axial direction; the cooling system includes a flow-confluence chamber, arranged in a circumferential direction of the stator support; an accommodating chamber, arranged in the circumferential direction of the stator support; in which the accommodating chamber is located at an inner side of the flow-confluence chamber in a radial direction and communicates with the flow-confluence chamber; a heat exchanger, arranged in the accommodating chamber or in the flow-confluence chamber; a circulating fan, arranged in the circumferential direction of the stator support and located at a side of the stator support in the axial direction, in which the circulating fan has an air inlet and an air outlet; the cooling air enters the ventilation chamber through the air outlet of the circulating fan, and the cooling air enters the air inlet of the circulating fan via the flow-confluence chamber, the heat exchanger and the accommodating chamber. An overall structure of the cooling system is simple and compact, and occupies smaller space.
