Abstract
A cooling structure for an electricity storage device includes: a secondary battery generating heat; a DC-DC converter generating heat in a quantity different from that of secondary battery; an exhaust path for passing air after cooling secondary battery generating heat in a relatively small quantity, and led to the outside of a vehicle; an exhaust path for passing air after cooling DC-DC converter generating heat in a relatively large quantity, and joining exhaust path; and a circulation path connected to exhaust path upstream of an air flow beyond a position at which exhaust path joins, and led to the inside of a vehicle compartment. With this configuration, there is provided a cooling structure for an electricity storage device in which the suppression of both increase in temperature and decrease in inner pressure inside the vehicle compartment can be effectively achieved at the same time.
