<p><P>PROBLEM TO BE SOLVED: To provide a battery-cooling structure capable of uniformly cooling the temperature of batteries that form a battery pack. <P>SOLUTION: In the battery-cooling structure wherein the battery pack made from a plurality of battery modules 2 is stored in a battery case 1 and cooling air is introduced into the battery case from a cooling air inlet 11 arranged on the battery case and the battery modules are cooled by the cooling air, and the cooling air is discharged outside the battery case from a cooling-air outlet 12 arranged on the battery case; an air-permeating porous member 13 for partitioning the inside of the battery case on a downstream side and an upstream side is arranged at a zone which is upstream rather than the battery pack in the battery case 1; and the air-permeating porous member 13 is formed by a pleated air-permeating porous material so as to make a flow of the cooling air on a downstream side of the air-permeating porous member set at an irregular flow. It is preferable that a pleated direction of the air-permeating porous member 13 be arranged, in parallel with the longitudinal direction of the battery modules 2. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
