Title:
HEAT DISSIPATION MEMBER AND MOTOR ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2019/142777
Kind Code:
A1
Abstract:
The present invention relates to a heat dissipation member and a motor assembly. A heat dissipation member (60) comprises: a heat dissipation cover (61) which can be disposed between an inverter case (21) for housing an inverter (20) and a motor casing (10) for housing a motor (8) that comprises a rotor (6) for rotating a drive shaft (5) and a stator (7), and which can connect to the inverter case (21) and the motor casing (10); and a heat dissipation plate (62) which is connected to the inner surface of the heat dissipation cover (61) and can partition an inverter space (66) where the inverter (20) is disposed and a fan space (67) where an internal fan (65) fixed to the drive shaft (5) is disposed. The heat dissipation plate (62) includes an air hole (70) where an airflow caused by the internal fan (65) can be formed between the inverter space (66) and the fan space (67).
