Title:
MOTOR COOLING APPARATUS AND AUTOMOBILE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/132261
Kind Code:
A1
Abstract:
According to the present invention, a motor is insertedly installed in a motor housing having a receiving space in which the motor is received; a cooling channel through which a cooling fluid flows is formed in the motor housing; a hollow space is formed in a rotor shaft of the motor; convection passages are formed between the bottom surface of the motor housing and a rotor, between a magnetic pole portion of a motor stator and the outer wall of the stator, and between the rotor and a motor housing cover; a hollow space and upper and lower air holes are formed in the rotor shaft so as to allow upper and lower convection passages to communicate with each other; and a blade part is formed in the rotor shaft, whereby the rotation of the rotor shaft causes the blade part to forcibly blow air in the convection passages and thereby generate air convection between the upper and lower portions, so that the cooling efficiency can be improved.
