Abstract

A vehicle includes a battery, a duct through which air for cooling the battery flows, and a bumper, wherein an opening portion at an end of the duct faces an outer face of the duct inside the bumper.

First claim

What is claimed is:

1. A vehicle on which a motor for running the vehicle is mounted, comprising:
a battery that is mounted on the vehicle and stores an electric power for driving the motor; and
a duct through which a heat exchange medium exchanging heat with the battery flows and that includes a first bend portion and a second bend portion, the first and second bend portions being a one piece portion and having a hook-shaped portion,
wherein a whole area of a single opening portion of the duct faces an outer face of the duct, and the single opening portion is integrally formed with the duct at an end of the second bend portion,
the first bend portion is located above an outer face of the duct that faces the single opening portion in a horizontal direction and protrudes in a first horizontal direction away from the single opening portion,
the second bend portion that is connected to the single opening portion and protrudes in a second horizontal direction opposite to the first horizontal direction and away from the single opening portion,
a bottom face of a boundary portion between the first and second bend portions is away from an upper end of the single opening portion in a vertical direction,
wherein the duct is continuously curved from the single opening portion to the outer face of the duct that faces the single opening portion in the horizontal direction,
wherein the duct includes a bellows shaped portion that is arranged at an allowing position of the vehicle to which submergence in water is allowed; and
wherein the duct includes the bellows shaped portion and two straight portions that are connected to both ends of the bellows shaped portion, respectively.

2. The vehicle according to claim 1 , further comprising a bumper of the vehicle,
wherein the whole area of the single opening portion of the duct faces the outer face of the duct inside the bumper.

3. The vehicle according to claim 2 , wherein the whole area of the single opening portion faces the outer face of the duct in a width direction of the vehicle.

4. The vehicle according to claim 2 , wherein the bumper has a guiding opening portion in a bottom face that guides the duct into the bumper, and
a spacing is formed between the guiding opening portion and the duct.

5. The vehicle according to claim 2 , wherein the duct is an exhaust duct configured to exhaust the heat exchange medium after the heat exchange with the battery, and
the bumper is located at a back end portion of the vehicle.

6. The vehicle according claim 1 , wherein the single opening portion is provided at a level higher than the allowing position.

7. The vehicle according to claim 1 , wherein the battery is located on a lower face of a floor panel of the vehicle.
