<p><P>PROBLEM TO BE SOLVED: To provide the cooling structure of a secondary battery capable of sufficiently decreasing noise. <P>SOLUTION: The cooling structure of the secondary battery has a suction passage 39 extending from suction ports 21m and 21n toward the secondary battery; and a cooling fan 36 positioned between the suction ports 21m and 21n and the secondary battery and installed in the suction passage 39. The suction passage 39 has an inner wall 24 extending from the position surrounding the suction ports 21m and 21n and guiding cooling air in almost the vertical direction. The suction passage 39 is bent at least once between the suction ports 21m and 21n and the cooling fan 36, and extended. The cooling structure of the secondary battery has a blocking plate 31 projecting from the inner wall 24 in the position separated from the suction ports 21m and 21n, opening the suction passage 39 in the position relatively far from the cooling fan 36, and blocking the suction passage 39 in the position relatively near from the cooling fan 36. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
