<p><P>PROBLEM TO BE SOLVED: To provide a battery pack attaining uniform cooling of respective battery modules while suppressing an increase in flow resistance of a refrigerant. <P>SOLUTION: A supply passage 5 is branched almost at right angles into cooling passages 9(A)-9(F) and the battery modules 2 in respective lines are cooled with air through the cooling passages 9(A)-9(F). The cooling passage 9(A) which is disposed on the upstream side of the supply passage 5 and into which air hardly flows, is faced with a part on the battery module 2, which is higher in cooling efficiency than the cooling passage 9(F) which is disposed on the downstream side and into which air flows readily. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
