ABSTRACT:
A rectifier in an alternating current generator for automotive vehicles is disclosed, which comprises a pair of conductive radiators for positive and negative sides, each having embedded therein diode chips arranged in a juxtaposed fashion, an insulated substrate facing the radiators and equipped with a terminal board to be connected with each of lead wires from corresponding diode chips, and cooling fins provided on each of the raidators, and a cooling fan provided on a rotor core for cooling the rectifier, the rectifier being positioned in air course in which air for cooling the radiators is introduced into the inside of the generator from the outside of a case bracket of the generator through air intake ports by the action of cooling fan such that radiators are placed in the radial direction in parallel relation to each other in the air course so that the insulating substrate is placed downstream in the air course.
