| 摘要 |
The present invention relates to a heat sink plate of an alternator for a vehicle which is capable of implementing an inherent operation of a heat sink by forming a hole in a plate and inserting a diode, forming a protrusion for stably fixing to a rear bracket for thereby implementing an inherent operation of a heat sink, enhancing a performance of a fan, simplifying an assembling work and implementing a stable installation of a regulator and other elements. In the heat sink plate of an alternator for a vehicle, the heat sink includes a circular plate formed based on a die casting method, a hole is formed at a certain portion of the circular plate, and a protrusion is inserted into a heat sink protrusion mounting groove which communicates with a circular plate mounting portion of a rear bracket in a certain circumferential surface of the circular plate and is engaged with a rear bracket in a heat sink of an alternator for a vehicle which includes a diode for changing an alternating current to a direct current for thereby radiating a heat.
