Title:
AC GENERATOR FOR VEHICLE
Document Type and Number:
Japanese Patent JP3675048
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an AC generator, for a vehicle, in which the cooling efficiency of a rectifying device can be enhanced by directly cooling a rectifying element.
SOLUTION: An embossed part 57 which is formed on every heat sink 53 of a rectifier as a rectifying device has a conical trapezoid shape, and four through holes 59 which are used as ventilation ports are formed in parts of a slope as a side face. A rectifying element 55 is attached to a flat face in a recess on the backside of the embossed part 57 so as to sandwich a copper plate 61. Since each of the four through holes 59 is formed so as to pass a part of the slope at the embossed part 57, a part of a cooling wind W which is introduced via an intake window in a rear cover flows to the backside of the heat sink 53 through the through holes 59, and a part flows along the surface of the heat sink 53. The rectifying element 55 is cooled directly by the cooling wind W which flows to the backside of the heat sink 53.
