LIQUID-COOLED MOTOR DEVICE

摘要

A liquid-cooled motor device includes a motor casing, a motor, a coolant casing and an impeller. The motor casing receives the motor, and defines a cooling space surrounding the retaining space, a coolant intake hole, and a coolant draining hole. The coolant casing defines a drawing space, a coolant inlet and a coolant outlet. The impeller is disposed in the drawing space and connected to an output shaft of the motor, and is rotated by the output shaft to draw a coolant into the drawing space via the coolant inlet, and to force the coolant into the cooling space via the coolant outlet and the coolant intake hole, such that the coolant removes heat generated by the motor, and is expelled from the cooling space via the coolant draining hole.

1. A liquid-cooled motor device comprising:
a motor casing defining a retaining space, a cooling space that surrounds said retaining space, a coolant intake hole that is in fluid communication with said cooling space, and a coolant draining hole that is in fluid communication with said cooling space; a motor disposed in said retaining space and having a rotatable output shaft; a coolant casing mounted to an outer surface of said motor casing, and defining a drawing space, a coolant inlet that is in fluid communication with said drawing space, vend a coolant outlet that is in fluid communication with said drawing space and said coolant intake hole; and an impeller co-rotatably connected to an end of said output shaft of said motor and disposed in said drawing space of said coolant casing, said impeller being rotated by said output shaft to draw a coolant into said drawing space via said coolant inlet, and to force the coolant to flow into said cooling space via said coolant outlet and said coolant intake hole, such that the coolant removes heat generated by said motor, and is expelled from said cooling space via said coolant draining hole.
