CURRENT-RECTIFYING ARRANGEMENT FOR A ROTARY ELECTRIC MACHINE, IN PARTICULAR FOR AN ALTERNATOR OF AN AUTOMOBILE, AND ROTARY ELECTRIC MACHINE COMPRISING SUCH AN ARRANGEMENT

摘要

The invention relates to a current-rectifying arrangement (1) for a multiphase rotary electric machine having a bearing (16, 18) provided with a perforated plate (3) including a heat sink (9) having first current-rectifying elements (8), second current-rectifying elements (10) supported by the plate (3), and a connector (113) inserted between the heat sink (9) and the plate (3), each of the first current-rectifying elements (8) being mounted in a blind cooling cell (A, B, C) defined by a projecting peripheral wall (91, 92, 93) and laterally by two projecting transverse walls extending from the outer periphery to the inner periphery of the heat sink (9), each cell comprising at least one outer hole defined by the inner periphery of the cell, and a transverse passage being provided between two transverse walls opposite two consecutive cells. The rotary electric machine includes such an arrangement. The invention can be used for an automobile alternator.
