Embodiment Construction

[0035] figure 1 The ventilation device 1 according to the invention is illustrated. Such a ventilating device includes a support 2 in which a motor 3 is placed. According to exemplary embodiments, such motors are of the brush and commutator type, but the invention preferably relates to brushless motors.

[0036] The electric motor 3 rotationally drives the impeller 4, which includes a disk 5 shown in dashed lines in this figure. Since the shaft of the electric motor is coupled to the disk 5, the disk forms a device for driving the impeller. Such a disk is, for example, solid in a certain sense, and its wall does not have openings. According to another alternative, such a disc 5 has multiple orifices.

[0037] On the periphery of such a disk, a plurality of blades 6 extend in a direction parallel to the extending direction of the motor shaft. The end of each blade is attached via a strap 7. Such an impeller 4 thus forms a squirrel-cage impeller, also called a radial turbine.

Abstract

The invention relates to a ventilation device (1) for a ventilation unit of a passenger compartment of a motor vehicle, said ventilation device comprising: an impeller (4) generating an air flow (11, 12) and which can be driven by an electric motor; and a printed circuit board ( 15) having fastened thereto at least one electronic component (19) capable of releasing heat. The printed circuit board (15) comprises at least one through hole (18) provided in a portion (21) of the printed circuit board (15). The ventilation device (1) is configured such that the airflow (11, 12) generated by the impeller (4) moves along said portion (21) of the printed circuit board (15).

Description

Technical field [0001] The technical field of the present invention is ventilation equipment, which is intended to establish the movement of airflow within a ventilation, heating, and / or air conditioning unit for a motor vehicle. Background technique [0002] Such ventilation, heating, and / or air conditioning units are usually formed by a housing, which defines a channel in which the airflow moves. The heat exchanger is located inside the housing to facilitate heating and cooling of the air flow distributed to the passenger compartment of the motor vehicle. The air flow is set to circulate in the housing by a ventilation device, which is controlled by a control device and includes a support portion accommodating an electric motor that drives the impeller to rotate. The support is installed on the housing, and the rotation of the impeller allows airflow to be sucked from outside the housing and distributed inside the housing. In this way, heat exchange occurs between the airflow...
