<p><P>PROBLEM TO BE SOLVED: To uniformly cool each battery module, while reducing the manufacturing cost, using a very simple structure. <P>SOLUTION: A power source device has a plurality of modules 1 housed in a case 2 in a parallel shape on the same plane. The case 2 has a cooling air suction duct 3 installed between one surface plate 2A and a battery group 10, and a cooling air exhaust duct 4 installed between the other surface plate 2A and the battery group 10; a counter plate 13 in which a plurality of lines of groovy recessed parts 14 are installed is arranged in the exhaust duct 14; and a cooling air passage 15 is installed between the battery module 1 and the counter plate 13. A through hole 16, permeating the cooling air passed through the air passage 15, is made in the bottom of the groovy recessed part. The air flow rate, passing through the through hole 16, is prescribed so that the flow rate in the through hole 16 installed in the groovy recessed part 14 on the exhaust side is higher than the flow rate of the through hole 16 installed in the groovy recessed part 14 on the inflow side. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
