<P>PROBLEM TO BE SOLVED: To provide a cooling device capable of suppressing that the temperature distribution of batteries becomes uneven, and a power supply device having the same. <P>SOLUTION: The cooling device is used which comprises a first case 2 to house batteries 1, a second case 3 to house the first case 2, a first cooling fan 4 for circulating a first coolant 12 in the first case 2, and a second cooling fan 6 for circulating a second coolant 13 in the second case 3. The batteries 1 are housed in the first case 2 so that a gap 2a to become a passage of the first coolant 12 may be formed between the inner face of the first case 2 and the outer face of the batteries 1. The first case 2 is housed in the second case 3 so that a gap 3a to become a passage of the second coolant 13 may be formed between the inner face of the second case 3 and the outer face of the first case 2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
