Title (EN) ROTATING ELECTRICAL MACHINE PROVIDED WITH AT LEAST ONE VENTILATION OPENING IN A HEAT SINK
(FR) MACHINE ELECTRIQUE TOURNANTE MUNIE D'AU MOINS UNE OUVERTURE D'AERATION DANS UN DISSIPATEUR DE CHALEUR
Abstract:
(EN) The invention relates mainly to a rotating electrical machine (100) capable of operating at least in alternator mode in order to supply power to a motor vehicle, said rotating electrical machine including: a heat sink (16) including a first surface, on which said electronic power circuit (15) is mounted, as well as a second surface, opposite said first surface and oriented towards said rear bearing (4); a protective cover (11) comprising at least one axial opening (11b), characterised in that said heat sink (16) comprises at least one main opening (16a), allowing the passage of said rotation shaft (2), and at least one ventilation opening, allowing the coolant to pass through said axial opening (11b) of said cover (11).
(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 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 capot de protection (11) comprenant au moins une ouverture axiale (11b), caractérisée en ce que ledit dissipateur de chaleur (16) comprend au moins une ouverture principale (16a) pour le passage dudit arbre de rotation (2) et au moins une ouverture d'aération (16b) permettant au fluide de refroidissement de passer de ladite ouverture axiale (11b) dudit capot (11)
