| 摘要 |
The present invention relates to an alternator for a vehicle which is capable of enhancing a performance of a fan by forming a hole in a flat plate with respect to a heat sink in the (-) direction between two heat sinks, inserting a diode therein for thereby obtaining an inherent heat sink operation and forming a certain surface at one side thereof opposite to the fan and supporting a brush holder and an alternator. In the present invention, there is provided an alternator for a vehicle in which a heat sink is formed by a circular die casting method, a hole in which a diode is installed is formed at a certain portion, and protrusion is formed in a certain portion of the circumferential surface for thereby enhancing a performance of a fan and supporting a brush holder and rectifier in an alternator for a vehicle in which a diode capable of converting an alternating current into a direct current is installed in a heat sink for thereby radiating heat.
