Title:
COOLING STRUCTURE FOR VEHICULAR ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2020/066339
Kind Code:
A1
Abstract:
In this cooling structure for a vehicular electric motor, the following are arranged around a vehicular electric motor (30): a compressor (50) that compresses air; a vortex tube (60) that forms a straight cylinder by which compressed air supplied from the compressor (50) is separated into warm air and cold air, and said warm air and said cold air are discharged individually; and a cold air duct (70) that guides the cold air discharged from the vortex tube (60) to the vehicular electric motor (30). As a result, it is possible to efficiently cool an electric motor and further improve the power consumption rate of the electric motor.
