Zusammenfassung:	PROBLEM TO BE SOLVED: To uniformly cool a battery module quickly and efficiently while reducing a heat loss by utilizing the heat of vaporization of a refrigerant. SOLUTION: This power supply device for a vehicle includes: a plurality of batteries 1; a battery case 2 for housing the batteries 1; and a cooling mechanism 3 for forcibly feeding the air to the batteries 1 in the battery case 2 to cool the batteries. The cooling mechanism 3 includes: an air cooling heat exchanger 4 for cooling the air blown to the batteries 1 by heat of vaporization of the refrigerant; a refrigerating cycle 5 for supplying the refrigerant to the air cooling heat exchanger 4; and a blower 6 for passing the air for the air cooling heat exchanger 4 to blow the air to the batteries 1. The air cooling heat exchanger 4 is provided in the battery case 2 and disposed under the batteries 1. The power supply device forcibly blows the air passing under the air cooling heat exchanger 3 upward to the batteries 1 to cool the batteries 1. COPYRIGHT: (C)2006,JPO&NCIPI
