Intake blower, notably for a motor vehicle heating, ventilation and/or air conditioning device, the blower comprising: • a turbine configured to be driven in rotation about an axis and having at least a first part termed "upper part" and a second part termed "lower part", • a blower housing surrounding the turbine and having a blower housing outlet extending along an axis, and - an air inlet housing comprising: - at least two distinct air inlets (24, 26) extending over a width of the air inlet housing 21, and - air guiding members (27, 28, 30) configured to direct at least one airflow intended to be admitted into the air inlet housing, the air guiding members comprising at least three flaps (27, 28, 30), these being a central flap and two lateral flaps (28, 30) arranged on either side of the central flap, said flaps (27, 28, 30) being arranged between said two distinct air inlets (24, 26) of the air inlet housing, such as to be able to move about a single pivot axle, the central flap extending over a portion of said width of the air inlet housing that is greater than the portion (d28, d30) of the width over which the two lateral flaps (28, 30) extend, the blower further comprising a dividing partition extending at least in part into the turbine, so as to separate a first airflow intended to pass through the first axial part of the turbine and a second airflow intended to pass through the second axial part of the turbine, characterized in that the pivot axle of the flaps (27, 28, 30) is parallel to the axis of extension of the blower housing outlet, and the dividing partition viewed in profile with a cross section in the direction of flow of the airflow exhibits at least two inflections, or changes in direction of the dividing partition, that is to say two bends each greater than 30°. • a turbine configured to be driven in rotation about an axis and having at least a first part termed "upper part" and a second part termed "lower part", • a blower housing surrounding the turbine and having a blower housing outlet extending along an axis, and - an air inlet housing - an air inlet housing - at least two distinct air inlets (24, 26) extending over a width of the air inlet housing 21, and - air guiding members (27, 28, 30) configured to direct at least one airflow intended to be admitted into the air inlet housing, the air guiding members comprising at least three flaps (27, 28, 30), these being a central flap and two lateral flaps (28, 30) arranged on either side of the central flap, said flaps (27, 28, 30) being arranged between said two distinct air inlets (24, 26) of the air inlet housing, such as to be able to move about a single pivot axle, the central flap extending over a portion of said width of the air inlet housing that is greater than the portion (d28, d30) of the width over which the two lateral flaps (28, 30) extend, the blower further comprising a dividing partition extending at least in part into the turbine, so as to separate a first airflow intended to pass through the first axial part of the turbine and a second airflow intended to pass through the second axial part of the turbine, characterized in that the pivot axle of the flaps (27, 28, 30) is parallel to the axis of extension of the blower housing outlet, and the dividing partition viewed in profile with a cross section in the direction of flow of the airflow exhibits at least two inflections, or changes in direction of the dividing partition, that is to say two bends each greater than 30°.
