Drive unit |
摘要 |
<p>In a drive unit which uses an electric motor as a driving source and which has an integrated inverter, the electric motor and the inverter are efficiently cooled. The drive unit comprises a drive unit case, an electric motor, and an inverter fixed to a drive unit case, and is provided with a coolant flow passage for them between the drive unit case and the inverter. The inverter is fixed to the drive unit case through a partition wall, and chambers, forming a two-layered coolant flow passage are formed between the partition wall and the drive unit case. As a result, the coolant which flows through the coolant flow passage acts as a two-step shielding means against the heat transmitted from the electric motor to the inverter. <IMAGE></p> |
