Vehicle AC generators have been required to be small, lightweight, and high output in order to improve vehicle performance and increase the density of engine compartments. For this reason, even if the cooling fins of the rectifier are downsized, it is necessary to keep the temperature rise within standard values. As disclosed in Japanese Utility Model Application No. 56-164678, this method uses a pair of roughly horse-shaped (semi-circular) cooling fins with different average radii, and a pair of cooling fins arranged in the same direction on one side of each of the cooling fins. and a plurality of diodes of different polarity, the pair of cooling fins are electrically insulated from each other, and one cooling fin is partially overlapped with the other cooling fin, A vehicle alternator having a structure in which diodes on the fins are not overlapped is known.

In order to reduce the temperature rise of the rectifier, the present invention minimizes thermal interference between rectifying elements by arranging the rectifying elements as far apart as possible.
The reason for this is that when a plurality of heat generating sources are provided on the same cooling fin, the thermal resistance between two adjacent heat generating sources changes depending on the position of each heat generating source. That is, the longer the distance between two adjacent heat generating sources, the greater the thermal resistance between the two heat generating sources. Therefore, the two heat sources can reduce the influence of heat generation on each other, thereby suppressing the temperature rise. In addition, by making the lead direction of each element the same and connecting the leads and terminals using molded terminals, it is possible to connect each part at the same time using solder, etc., and to improve work efficiency. It can be fixed with bolts to improve vibration resistance.
