ABSTRACT:
A vehicle's AC generator is provided with a rotor magnetic pole core assembly fixedly mounted on a rotary shaft and excited through an exciting coil, stator-coil-mounted stator cores surrounding the magnetic pole core assembly, first and second brackets supporting the stator cores and rotatably supporting the rotary shaft through bearings, a pair of fans provided on both ends of the rotor magnetic pole core assembly, to allow cooling air to flow in the space defined by the first and second brackets, a rectifier, and a voltage regulator. In addition, a cooling solution circulating structure, made of a material high in thermal conductivity, is provided on the side of one of the first and second brackets. The cooling solution circulating structure, which has an upper frame and a lower frame, has a flow path inside to which a cooling solution is supplied from outside. The rectifier and the voltage regulator are mounted on the other surface of the cooling the generator with high efficiency and preventing the temperature increase of the generator.
