<p><P>PROBLEM TO BE SOLVED: To provide a battery cooling structure capable of more uniformly cooling batteries constituting a battery pack. <P>SOLUTION: In the battery cooling structure guiding cooling wind into a battery case 1 from a cooling wind guide port 11 fitted to the battery case, cooling a battery module 2 with cooling wind, and exhausting cooling wind outside the battery case from a cooling wind guide-out port 12 fitted to the battery case, such a flow control board 13 as to zone an inside of the battery case into a downstream side and an upstream side is provided at a region to be at a further upstream side than the battery pack in the battery case, and a plurality of slits 132 are provided substantially in parallel at the flow control board 13 so that a flow of the cooling wind at the downstream side of the flow control board 13 is to be an unsteady flow. Preferably, the slits 132 are set substantially in parallel to a longitudinal direction of the battery module 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
