Abstract

A cooling duct structure for a battery unit includes a cooling duct which is located above the battery unit, and extends toward an upper portion of an auxiliary mounting space. The cooling duct is separated into an upper duct and a lower duct in a middle portion thereof. The lower duct is fixedly connected to the battery unit, and can be mounted on the vehicle together with the battery unit. The upper duct and the lower duct, which are separated from each other, can be connected to each other when the battery unit is fixed to and mounted on the vehicle.

Claims

1. A cooling duct structure for a battery unit mounted under a floor panel of a vehicle, the cooling duct structure comprising:

an auxiliary mounting space protruding upward under the floor panel and being capable of accommodating an auxiliary device; and

a cooling duct and a cooling fan configured to take external air to cool a battery in the battery unit and then exhaust the air,

wherein the cooling duct is located above the battery unit and extends toward an upper portion of the auxiliary mounting space,

wherein the cooling duct is separated into an upper duct and a lower duct in a middle portion thereof,

wherein the lower duct is fixedly connected to the battery unit, and is configured to be mounted on the vehicle together with the battery unit, and

wherein the upper duct and the lower duct, which are separated from each other, are configured to be connected to each other when the battery unit is fixed to and mounted on the vehicle.

2. The cooling duct structure for a battery unit according to claim 1, wherein the upper duct is disposed above the auxiliary device, and is mounted on the vehicle together with the auxiliary device.

3. The cooling duct structure for a battery unit according to claim 1, wherein

a front end portion of the upper duct is formed as a case having a capacity,

the case is flat in a up-down direction, and

the case is disposed on the upper portion of the auxiliary mounting space while being arranged to be spaced upward from the auxiliary device disposed below the case.

4. The cooling duct structure for a battery unit according to claim 3, wherein

an opening facing downward is formed in an outer side wall of the case, and

a water shielding plate is disposed in the case.

5. The cooling duct structure for a battery unit according to claim 2, wherein

a front end portion of the upper duct is formed as a case having a capacity,

the case is flat in a up-down direction, and

the case is disposed on the upper portion of the auxiliary mounting space while being arranged to be spaced upward from the auxiliary device disposed below the case.

6. The cooling duct structure for a battery unit according to claim 5, wherein

an opening facing downward is formed in an outer side wall of the case, and

a water shielding plate is disposed in the case.
