Title (EN) ROTARY ELECTRIC MACHINE FITTED WITH COOLING FINS
(FR) MACHINE ELECTRIQUE TOURNANTE MUNIE D'AILETTES DE REFROIDISSEMENT
Abstract:
(EN) The invention chiefly relates to a rotary electric machine (100) capable of operating at least in alternator mode to supply power to an automotive vehicle, said rotary electric machine including: -a power electronic circuit (15) electrically connected to the phase windings of the stator (3); -a heat sink (16) including, on the one hand, a first face on which said power electronic circuit (15) is mounted and, on the other hand, a second face opposite said first face and oriented towards said rear bearing (4); -a passage (17) for the flow of coolant between an upper face of said rear bearing (4) oriented towards said heat sink (16) and the second face of said heat sink (16), characterized in that the second face of said heat sink (16) includes cooling fins (18), and in that at least one axial end of a fin (18) extends axially at least up to the level of the upper face of said rear bearing (4).
(FR) L'invention porte principalement sur une machine électrique tournante (100) apte à fonctionner au moins en mode alternateur pour fournir une puissance à un véhicule automobile, ladite machine électrique tournante comportant: -un circuit électronique de puissance (15) connecté électriquement aux enroulements de phase du stator (3), -un dissipateur de chaleur (16) comportant d'une part une première face sur laquelle est monté ledit circuit électronique de puissance (15), et d'autre part, une seconde face, opposée à ladite première face et orientée vers ledit palier arrière (4), -un passage (17) d'écoulement de fluide de refroidissement entre une face supérieure dudit palier arrière (4) orienté vers ledit dissipateur de chaleur (16) et la seconde face dudit dissipateur de chaleur (16), caractérisée en ce que la seconde face dudit dissipateur de chaleur (16) comporte des ailettes de refroidissement (18), et en ce qu'au moins une extrémité axiale d'une ailette (18) s'étend axialement au moins jusqu'au niveau de la face supérieure dudit palier arrière (4).
