Title (EN) PROPELLER FOR FAN OF A THERMAL SYSTEM OF A MOTOR VEHICLE, FAN AND THERMAL SYSTEM COMPRISING SUCH A PROPELLER
(FR) HÉLICE POUR VENTILATEUR DE SYSTÉME THERMIQUE DE VÉHICULE AUTOMOBILE, VENTILATEUR ET SYSTÈME THERMIQUE COMPRENANT UNE TELLE HÉLICE
Abstract:
(EN) The propeller (16) for a fan (14) of a thermal system (10) of a motor vehicle comprises a receiving bowl (22) for receiving a motor (18) of the propeller (16) and at least one blade (34) linked to the receiving bowl (22), the receiving bowl (22) further comprising: - a central member (26) comprising at least one through-opening (30), - a crown (28) extending around the central member (26), the blade (34) extending radially outwards from the crown (28), and - at least one rib (36) arranged on a front face of the crown (28), with reference to a direction of flow of an air flow (F) generated by the propeller (16), extending radially outwards so as to have a curved shape oriented in the opposite direction to a direction of rotation of the propeller (16).
(FR) L'hélice (16) pour ventilateur (14) de système thermique (10) de véhicule automobile comprend un bol de réception (22) d'un moteur (18) de l'hélice (16) et au moins une pale (34) reliée au bol de réception (22), le bol de réception (22) comprenant en outre : - un organe central (26) comprenant au moins un orifice traversant (30), - une couronne (28) s'étendant autour de l'organe central (26), la pale (34) s'étendant radialement vers l'extérieur depuis la couronne (28), et - au moins une nervure (36) disposée sur une face avant de la couronne (28), en référence à un sens de circulation d'un flux d'air (F) généré par l'hélice (16), s'étendant radialement vers l'extérieur de façon à présenter une forme courbe orientée en sens inverse d'un sens de rotation de l'hélice (16).
