Cooling structure of oil-cooled motor, oil-cooled motor and vehicle

The invention relates to the technical field of motors, in particular to a cooling structure of an oil-cooled motor, the oil-cooled motor and a vehicle. The cooling structure of the oil-cooled motor comprises a shell; the stator iron core is arranged in the shell, an open slot is formed in the stator iron core, and the open slot is communicated with a stator slot in the stator iron core; the winding is arranged in the stator slot and is far away from one end of the open slot; the packaging device wraps the winding, the packaging device is used for blocking the stator groove, and the inner surface of the packaging device, the open groove and the stator groove jointly form a cooling flow channel; and the oil return groove is communicated with the cooling flow channel. According to the cooling structure of the oil-cooled motor, the inner surface of the packaging device, the open slots and the stator slots jointly form a cooling flow channel, cooling oil can fully, comprehensively and uniformly flow through the w
