Abstract
An alternator includes a housing body, and an electronics chassis electrically in common with output voltage (B+) of the alternator, conductively isolated from heat of the housing body, and having cooling fins. An air router intermediate the housing body and the chassis directs cooling air from air intake openings to the cooling fins. An electric machine includes a housing with air intake openings, an electronics chassis having rectifier electronics mounted thereon and having axially-extending cooling fins, and an air router secured intermediate the housing body and the electronics chassis, for routing the cooling air from the air intake openings directly to the cooling fins. An alternator includes a housing, an electronics chassis electrically in common with (B+), air intake openings, and an air router secured intermediate the housing body and the electronics chassis, the air router structured for routing air from the air intake openings directly to the electronics chassis.
