Problems solved by technology

[0006] However, depending on the use of the motorized fan unit, the cooling provided by this configuration of the prior art results in a pressure drop in the primary airflow and, at a constant flow rate, an increase in the noise intensity, which can then compromise the performance of the motorized fan unit. performance

Embodiment Construction

[0028] The subject of the invention is a motorized fan unit for a motor vehicle, referenced 1 in the accompanying drawings.

[0029] The motorized fan unit preferably forms part of a heating, ventilation and / or air conditioning arrangement of the motor vehicle.

[0030] Such as figure 1 and figure 2 As can be seen in , the motorized fan unit 1 includes a motor 2 , a fan 3 and a control module 4 for controlling the motor 2 .

[0031] The fan 3 is controlled by the motor 2 and moves the airflow F. exist figure 1 and figure 2 Among them, the fan 3 is in the form of an impeller.

[0032] The control module 4 comprises an electronic board equipped with electronic components which must be cooled in order to avoid any failure of the motorized fan unit.

[0033] Such as figure 1 and figure 2 As shown, the motorized fan unit 1 delimits two air circulation ducts: a first duct, referred to as the main duct, referenced 5 , and a second duct, referred to as the cooling duct, ref...

Abstract

The invention relates to a motorized fan unit for a motor vehicle, comprising a motor (2), a fan (3) for moving an air flow (F) that is configured to be controlled by the motor (2), and a control module (4) for controlling said motor (2), the control module (4) comprising an electronic card, the motorized fan unit delimiting a main air-flow circulation duct (5) and a cooling duct (6) configured to cool said electronic card of the control module, the duct (6) comprising an inlet (7) provided with a deflector (8) for diverting a portion of the air flow into the duct (6), the deflector (8) being mounted movably according to an air flow rate in the main duct for the purpose of increasing an air flow rate in the cooling duct (6) with the speed of the air flow in the main duct (5).

Description

technical field [0001] The subject of the invention is a motorized fan unit for a motor vehicle. Background technique [0002] Preferably, such a motorized fan unit forms part of a heating, ventilation and / or air-conditioning arrangement of a motor vehicle which regulates the temperature of an airflow intended to be provided for the vehicle interior. [0003] The motorized fan unit, for its part, is used to circulate an airflow into and through the heating, ventilation and / or air conditioning unit until the air enters an outlet opening inside the vehicle. [0004] A motorized fan unit in a known manner comprises an electric motor, for example with brushes, on which an impeller is mounted to cause the air to move, and means for controlling the electric motor, the electric motor control means comprising an electronic board. [0005] In general, motorized fan units are equipped with ducts for cooling the motor. The electronic board is cooled in the main flow, thereby avoiding...
