<p><P>PROBLEM TO BE SOLVED: To provide a battery cooling structure which can effectively cool batteries so as to make uniform the battery temperature of a battery pack even if a width of a cooling air passage is changed by expansion of the batteries constituting the battery pack. <P>SOLUTION: A battery cooling structure is configured such that a battery pack 1, which is made up of flat-plate like batteries 2, 2 aligned at predetermined intervals in a laminated manner, is housed in a battery case 6, and that the batteries are cooled by cooling air supplied to flow through gaps between the batteries. A flow control plate 5 is arranged upstream or downstream of the battery pack 1 so as to block a passage of the cooling air. The flow control plate 5 is provided with slits 51, 51 each extending in a direction along the gap between the batteries. The cooling air is made to flow through the slits 51 from upstream to downstream of the flow control plate so that the slits 51 and the gaps between the batteries serve as a plurality of flow channels individually arranged in parallel. When viewed along a flow direction of the cooling air between the batteries, a width S of each slit is made equal to or smaller than a gap d between batteries (S≤d). <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
