COOLING STRUCTURE FOR BATTERY PACK

摘要

PROBLEM TO BE SOLVED: To restrain damage caused by heat generation of an electric device even though a space for storing the electric device is limited.

SOLUTION: A cooling structure includes a passage formed such that intake air absorbed from the outside of the battery pack 10 penetrates through the inside of a battery module assembly 110 arranged at an upstream side, the air is circulated along the outer periphery of a compartment for storing a DC-DC converter 152 arranged at a downstream side, the air is discharged to the outside of a battery pack, and a cooling fan for circulating a cooling medium to the passage. An opening for connecting between a space in the compartment and passage 106 is formed on a wall surface of the passage 106 adjacent to the compartment for storing the DC-DC converter 152.
