ABSTRACT:
To provide an easily and essentially automatically manufactured rectifier array for an automotive alternator, two bus rails 1a, 1b, in the form of sheet metal strips, are punched for insertion of connecting studs 6 of rectifier diodes. The bus rails, with the diodes assembled thereto, are placed parallel to, and spaced from each other, and oppositely directed studs 6 from the diodes 4 are connected together by connecting strips 2a, 2b, 2c, which will function as electrical connecting elements and heat sink and heat dissipating plates to conduct off heat arising in operation of the diodes. The subassembly can then be connected into an alternator, with an air directing baffle directing axial airflow. The angled-off cooling and connecting strips which, preferably, are wider than the bus rails, permit placing the assembly to fit around the alternator shaft and associated structures, such as slip rings and the like, with airflow being directed along the major plane of the respective rails and strips, thus permitting efficient flow of cooling air past the strips, efficient cooling, and essentially automated assembly.
