Liquid immersion type directional cooling motor

The invention discloses a liquid immersion type directional cooling motor. A spacer bush is arranged between a stator and a rotor of the motor to separate the stator and the rotor to form an independent cavity; cooling liquid flows into the spiral liquid channel of the inner cavity of the base through the liquid inlet nozzle and exchanges heat with the outer circle of the stator iron core to take away heat of the outer circle of the iron core. Cooling liquid entering the motor enters the winding end portion on one side in the motor through the liquid inlet to be soaked and cooled, then flows into the winding end portion on the other side of the motor through the stator notch to be soaked and cooled, and finally flows out through the four liquid outlet nozzles until liquid path circulation cooling in the motor is finished. According to the scheme, the motor performance index is effectively improved through efficient directional heat dissipation of the heat source stator part of the motor. 本发明公开了一种液浸式定向冷却电机，电机定
