COOLING DEVICE FOR MOTOR

PROBLEM TO BE SOLVED: To provide a cooling device for a motor provided with a cooling jacket with which an inner surface has at least one cooling groove by using liquid cooling. SOLUTION: The cooling device for a motor is provided with a cooling duct formed between the cooling jacket and the surface of individual component members. The surface of individual component members can demarcate at least one part of wall part of the cooling duct. The cooling duct directs a coolant object along to at least one part of the surface of the individual component member, in order that heat may be dissipated from the motor. An inlet port can carry out fluid with the cooling duct. This inlet port may be so constituted that the coolant object may be received and the coolant object may be introduced into the cooling duct. An outlet port can also carry out the fluid communication with a cooling duct. COPYRIGHT: (C)2005,JPO&NCIPI
