<P>PROBLEM TO BE SOLVED: To efficiently and homogeneously cool a battery housed in a case while protecting it from humidity, dusts, and/or salts. <P>SOLUTION: A power supply device houses a plurality of element batteries 1 having a convex electrode 6 at one end in a case 3. The power supply device arranges and installs a heat exchange fin 13 in the case 3. This heat exchange fin 13 installs a battery holding part 14 to couple the end part of the element batteries 1 in a thermally coupled state at both faces. The battery holding part 14 of the heat exchange fin 13 couples the end part which is one end part of the element batteries 1 and in which the convex electrode 6 is installed with the bottom part of the opposite side, and cools the element batteries 1 coupled with the battery holding part 14 from the bottom part by the heat exchange fin 13. <P>COPYRIGHT: (C)2007,JPO&INPIT |
