摘要

The invention relates to a voltage regulator device for a rotary electrical machine, notably an alternator and/or alternator-starter of a motor vehicle, said regulator device (14) comprising one or more electronic components (28) able to contribute to controlling said electric machine, a heat sink (30) having parallel heat-dissipating vanes (32), said heat sink being in a heat-exchange relationship with said component or components, and a support (34) on which said heat sink is positioned. Said support is able to be mounted on the electric machine in such a way that the vanes of the heat sink can orient an air flow towards a region of depression provided between said support and said machine. The invention also relates to a bearing of an electric machine equipped with a such a device and to an electric machine equipped with such a bearing.
