<P>PROBLEM TO BE SOLVED: To provide a cooling structure of an on-vehicle electric system wherein an inverter and electrical apparatuses, such as an alternating-current generator- motor, controlled by the inverter can be cooled through a structure of small scale. <P>SOLUTION: The inverter 54 and a three-phase alternating-current generator- motor 50 are placed with an air-cooling heat sink 52 in-between. Further, measures are taken so that cooling air Y1 flowing through the air-cooling heat sink 52 is turned back through a duct 56 for cooling air and flows to a rotor 58 through a cooling fan 62. Furthermore, a heat insulator 51 for thermal insulation is placed between the three-phase alternating-current generator-motor 50 and the air-cooling heat sink 52. <P>COPYRIGHT: (C)2003,JPO |
