Electrically driven vehicle
First Claim
1. An electrically driven vehicle comprising:
- a first electric motor configured to generate motive power to operate a first driving wheel;
a second electric motor configured to generate motive power to operate a second driving wheel;
a first power drive device corresponding to the first electric motor and extending in a first direction;
a second power drive device corresponding to the second electric motor and extending in the first direction;
a first heat sink which has a plurality of first cooling fins extending in a second direction orthogonal to the first direction and which is attached to a first lateral surface of the first power drive device;
a second heat sink which has a plurality of second cooling fins extending in the second direction and which is attached to a second lateral surface of the second power drive device, the second lateral surface being provided to face the first lateral surface;
a baffle member including a first partition wall which is provided integrally with the baffle member and which is arranged between the first heat sink and the second heat sink, the baffle member closing a space defined between the first power drive device and the second power drive device at a first end and a second end of the space, the first end being opposite to the second end in the first direction;
a first air guide passage which houses the first heat sink and in which cooling air is to flow in the second direction, the first air guide passage being provided between the first partition wall and the first power drive device; and
a second air guide passage which houses the second heat sink and in which cooling air is to flow in the second direction, the second air guide passage being provided between the first partition wall and the second power drive device,wherein the first cooling fins and the second cooling fins are disposed within the first air guide passage and the second air guide passage, respectively, so as to face each other.

Abstract
An electrically driven vehicle includes a first electric motor, a second electric motor, a first power drive device, a second power drive device, a first heat sink, a second heat sink, a baffle member, a first air guide passage, and a second air guide passage. The baffle member closes a space defined between the first power drive device and the second power drive device at a first end and a second end of the space. The first air guide passage houses the first heat sink. The first air guide passage is provided between a first partition wall and the first power drive device. The second air guide passage houses the second heat sink. The second air guide passage is provided between the first partition wall and the second power drive device.
