Abstract

A battery cooling structure which cools a battery equipped on a vehicle, the battery cooling structure including: a fan sending an air to cool the battery; and a sound insulation wall including a sound insulation material which insulates noise wherein the sound insulation wall faces an exhaust outlet of the fan.

Claims

1. A battery cooling structure which cools a battery equipped on a vehicle, the battery cooling structure comprising:

a fan sending an air to cool the battery; and

a sound insulation wall including a sound insulation material which insulates noise, wherein

the sound insulation wall faces an exhaust outlet of the fan.

2. A battery cooling structure according to claim 1, wherein

the sound insulation wall is placed outside of an interior material of a luggage compartment of the vehicle

3. A battery cooling structure according to claim 2, wherein:

an extension part, extending outside of the luggage compartment, is placed on the interior material; and

the sound insulation wall is formed on the extension part.

4. A battery cooling structure according to claim 2, wherein:

the interior material includes a pair of side wall portions on both sides of the vehicle in a vehicle-width direction, and a floor part connecting the pair of side wall portions and forming a base of the luggage compartment;

the fan is placed outside of the luggage compartment, so that the exhaust outlet faces an inside portion of the vehicle in the vehicle-width direction; and

the sound insulation wall extends downward from the floor part.
