Vehicle and cooling structure for power source apparatus mounted on vehicle

A vehicle on which a power source apparatus is mounted, comprising:

• the power source apparatus disposed in an in-car space of the vehicle;
• a cooling apparatus supplying air within the in-car space to the power source apparatus;
• a cooling duct which the air discharged from the power source apparatus flows;
• and
• a first cooling flow path connected to the cooling duct and formed by a pillar of the vehicle;
• a second cooling flow path connected to the cooling duct and formed by a vehicle frame formed on each side of a lower portion of the pillar and a stepped portion provided for the vehicle frame;
• and
• a third cooling flow path connected to the cooling duct and formed by the vehicle frame and a scuff plate portion provided for the vehicle frame,
• wherein the first cooling flow path, the second cooling flow path, and the third cooling flow path are coupled to each other through the pillar, and the pillar is directly connected to the cooling duct disposed under a seat mounted in the in-car space between the power source apparatus and the pillar, and
• wherein the first cooling flow path extends from the lower portion of the pillar to a roof portion of the vehicle, and the air is discharged from the roof portion to the in-car space after the air flows through the first cooling flow path.
