    • The invention relates to an electrical machine, preferably an alternator (10) for motor vehicles, comprising a rectifier assembly (11a) that is fixed to an end shield (23) of the machine. Said rectifier assembly is cooled by a fan (27) that operates in the end shield (23), the diodes being positioned on a negative connecting plate (15) and a positive connecting plate (17) of the rectifier assembly (11). The aim of the invention is to evacuate the dissipated heat from the rectifier assembly (11a) in an advantageous manner. To achieve this, the rectifier assembly is located in an opening in the front face (32) of the end shield (23) and is connected in an electrically and thermally conductive manner by one of its two connecting plates (15 and 17) to a cooling body (33), which is connected to the exterior of the end shield (23) and covers the opening (32). The cooling air that is thus taken in by the fan (27) first flows from the exterior across the cooling body (33) in a radial manner towards the interior, entering the machine in the vicinity of the shaft through orifices (30) in the end shield (23) and from here, having reached the fan (27), subsequently flows past the other connecting plate (15 and 17) in a radial manner towards the exterior.
    • 电机中,优选用于机动车辆的三相发电机(10),安装有一个在机器整流器单元的支承板(23)(IIa)中,一个轴承罩(23)风扇(27)的运行进行冷却,其特征在于,在所述二极管 负端子板(15)和所述整流器单元(11)的正极端子板(17)坐。 这在轴承板(23)的端面开口(32)被布置成实现从整流器单元的热损失(11a)和在其两个端板中的一个(15和17)与冷却体低耗散(33)的电流和 导热地,在外部固定在支承板(23)和覆盖所述开口(32)。 由风扇表征(27)吸入的冷却空气可最初从外部经由冷却体(33)通过在所述支承板中的开口(30)流径向向内的区域中的轴附近(23)到达入机器和从那里到所述风扇(27)沿径向 向外的另一连接板(15或17)流过。
