<p><P>PROBLEM TO BE SOLVED: To improve the cooling efficiency of a battery pack module and a battery pack for storing its battery pack module in a casing by forming the laminated body by laminating a plurality of flat thin batteries in the vertical direction of a vehicle, and by juxtaposing the laminated body on the same plane. <P>SOLUTION: In the battery pack module 20, battery laminated bodies 23A to E for forming clearance between laminated flat batteries 21A to E and flat batteries 22A to E as a refrigerant passage are arranged in a plane shape in the flowing direction of a refrigerant. The clearance between the flat batteries and the flat batteries is formed so that the battery laminated body positioned on the downstream side in the flowing direction of the refrigerant becomes smaller, and the cross-sectional area of the refrigerant passage becomes small toward the downstream side from the upstream side of the refrigerant. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
