ON-VEHICLE COOLING DEVICE OF ELECTRIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an on-vehicle cooling device for cooling an electric apparatus capable of avoiding a problem of NV (Noise & Vibration) while maintaining the high cooling performance.

SOLUTION: In a traveling battery 220, air in a cabin is sucked in an inlet part 2200 (the direction of an arrow A) of a battery pack cover 2100 by a battery cooling electric-driven fan 2110. The sucked air flows from an inlet side chamber to an outlet side chamber provided in the battery pack cover 2100, and is discharged from an outlet part 2210. The outlet part 2210 is connected to an intake duct 2220 of the battery cooling electric-driven fan 2110 (which is also an exhaust duct from the battery pack cover 2100). The intake duct 2220 has a shape bent in the direction inseparable from the traveling battery 220.
