COOLING STRUCTURE FOR VEHICULAR BATTERY

摘要

PROBLEM TO BE SOLVED: To cool a plurality of batteries.SOLUTION: A cooling structure for vehicular battery is characterized in that a plurality of battery boxes 11 which accommodate batteries and each have an air suction port 11a for sucking cooling air and an air exhaust port 11b for discharging hot air 22 after cooling are mounted on a roof panel 10a of a vehicle 10, and a battery cover 13 which covers the plurality of battery boxes 11 is provided for the roof panel 10a. A partition 16 is provided which partitions a space surrounded with the roof panel 10a and battery cover 13 and accommodating the plurality of battery boxes 11 into air suction chambers 17 on both width-directional sides of the vehicle 10 and an air exhaust chamber 18 sandwiched between the air suction chambers 17 and extending to the front and rear. The plurality of battery boxes 11 are arrayed in two columns separately in the width direction of the vehicle 10 so as to have air suction ports 11a opened to the air suction chambers 17 and air exhaust ports 11b opened to the air exhaust chamber 18. Suction and exhaust ports 13g which communicate with the air exhaust chamber 18 are formed in the front and rear of the battery cover 13.
