Title
(EN) ALTERNATOR WITH DUAL AXIAL AIRFLOW
(FR) ALTERNATEUR À DOUBLE FLUX D'AIR AXIAL
Abstract
(EN) A vehicle alternator comprises a rotor and a stator positioned within a housing. The housing includes a front face, a rear face, and a outer wall extending between the front face and the rear face. The front face includes a plurality of air inlet holes, and the rear face including a plurality of air outlet holes. The outer wall is void of air holes that extend through the outer wall. The rotor is positioned within the housing and configured to rotate about an axis. The stator is positioned within the housing between the rotor and the outer wall of the housing. The stator includes a core with an outer surface, a front end and a rear end. A plurality of substantially axial air passages are positioned between the outer wall of the housing and the outer surface of the stator core.
(FR) L'invention porte sur un alternateur pour véhicule. L'alternateur selon l'invention comprend un rotor et un stator positionnés dans une carcasse. La carcasse comprend une face avant, une face arrière et une paroi extérieure qui s'étend entre la face avant et la face arrière. La face avant comprend une pluralité de trous d'entrée d'air et la face arrière comprend une pluralité de trous de sortie d'air. La paroi extérieure est exempte de trous d'air s'étendant à travers la paroi extérieure. Le rotor est positionné dans la carcasse et conçu pour tourner autour d'un axe. Le stator est positionné à l'intérieur de la carcasse, entre le rotor et la paroi extérieure de la carcasse. Le stator comprend un noyau ayant une surface extérieure, une extrémité avant et une extrémité arrière. Une pluralité de passages d'air sensiblement axiaux sont positionnés entre la paroi extérieure de la carcasse et la surface extérieure du noyau de stator.
