ABSTRACT:
A rectifying apparatus for a.c. dynamo for vehicle is disclosed. The rectifying apparatus of the present invention comprises: rectifier elements for rectifying a.c. current; through holes for fixing the rectifier elements; and a radiator plate for radiating heat generated by the rectifier elements. The rectifier elements are disposed at a part of the through holes, while the blocking members are disposed at the rest of the through holes. The open through holes at which the rectifier elements are not disposed are blocked by the blocking elements, thereby preventing the cooling wind from passing through the through holes, prohibiting the concentrated leakage of the cooling wind and thus obtaining a cooling effect as designed.
