Abstract: A motorized ventilation device for a motor vehicle, comprising an impeller (1) free to rotate about an axis (X) and formed by a cup (2), on which blades (3) are disposed, a bell cap (6) of an electric motor partly housed inside the cup (2), a centrifugal device (8) disposed between the cup (2) and the bell cap (6) and configured to guide and to accelerate an air flow (F2). The cup (2) comprises at least one opening (20, 27) for the passage of the air flow (F2) and the bell cap (6) comprises at least one orifice (65, 66, 67) for the passage of the air flow (F2).

Abstract: The invention relates to a thermal control system (100) for a vehicle, the thermal control system (100) comprising at least one first heat exchanger (110) and at least one second heat exchanger (120) that are arranged in series, the first heat exchanger (110) extending mainly on a first plane (P1) intersecting a second plane (P2) on which the second heat exchanger (120) mainly extends such that the first heat exchanger (110) is closer to the second heat exchanger (120) at respective first ends (111, 121) of the two heat exchangers (110, 120) and the first heat exchanger (110) is farther away from the second heat exchanger (120) at respective second ends (112, 122) of these two heat exchangers (110, 120).

Abstract: The fan impeller (10) comprises a hub (14) and blades (12) extending radially outward from the hub, the blades having a flattened airfoil profile cross section with a leading edge (24) and a trailing edge (26) between which a chord is defined. The blade (12) has a relative thickness that reached its maximum value (Emax) in the first quarter of the length of the chord measured from the leading edge (24), the relative thickness being defined by the ratio between the thickness of the blade and the length of the chord. The invention finds an application particularly in motor vehicle engine cooling fan impellers.
