<p><P>PROBLEM TO BE SOLVED: To provide a battery pack allowing for improving the cooling efficiency of secondary cells. <P>SOLUTION: The battery pack is equipped with 8 sets of battery stacks 30a to 30h, with each being constituted of 10 stacked secondary cells; heat sinks 20 between which the secondary cells 10a to 10j are interposed; a case 40, in which the battery stacks 30a to 30h are disposed on the same plane and housed in an internal space 41 thereof; an inlet duct 50, communicating the exterior of the battery pack and the internal space 41 of the case 40; an outlet duct 60, communicating the internal space 41 of the case 40 and the exterior of the battery pack; and a fan 70 disposed in the outlet duct 60, wherein the cooling wind taken into the internal space 41 of the case 40 via the inlet duct 50 by negative pressure produced by the rotating drive of the fan 70 enters each passage formed in the heat sinks 20 and indirectly cools the secondary cells, and enters each flow channel formed between each battery stacks 30a to 30h and directly cools the secondary cells. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
