COOLING STRUCTURE OF POWER STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce frequency of maintenance work by: collecting dust and the like flowing into a circulation route of air supplied to a power storage device for temperature adjustment; and curbing a reduction in cooling performance due to collected dust.SOLUTION: A cooling structure of a power storage device comprises: a blower which supplies the power storage device outputting energy used for vehicle travel with air for temperature adjustment; and a collection duct which is arranged in a circulation route of the air supplied to the power storage device at an upstream side of the power storage device and the blower. The collection duct has: a guide blade section which generates a swirl flow of air by applying centrifugal force to the air flowing into the collection duct; a duct main body section which is installed at a downstream side of the guide blade section and allows the swirl flow to pass therethrough; and a filter section that includes a collection surface which is extended in a flow direction of the swirl flow and which collects dust accumulated on an inner surface of the duct main body section by the swirl flow.
