Embodiment Construction

[0035] figure 1 A ventilation device 1 according to the invention is illustrated. Such a ventilation device comprises a support 2 in which an electric motor 3 is accommodated. According to an exemplary embodiment, such a motor is of the brush and commutator type, but the invention preferably relates to a brushless motor.

[0036] An electric motor 3 rotationally drives an impeller 4 comprising a disc 5 shown in dashed lines in the figure. Since the shaft of the motor is coupled to the disc 5, this disc forms the means for driving the impeller. Such a disk is, for example, solid in the sense that its walls have no openings. According to another alternative, such a disc 5 has a plurality of orifices.

[0037] On the periphery of such a disc, a plurality of vanes 6 extend in a direction parallel to the direction of extension of the motor shaft. The end of each blade is attached via a band 7 . Such an impeller 4 thus forms a squirrel-cage impeller, also known as a radial tur...

Abstract

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

Description

technical field [0001] The technical field of the invention is ventilation devices, which are intended to establish the movement of airflows within ventilation, heating, and / or air conditioning units for motor vehicles. Background technique [0002] Such ventilation, heating, and / or air-conditioning units are usually formed by housings that define channels in which the airflow moves. A heat exchanger is located inside the housing to facilitate heating and cooling of the airflow distributed into the passenger compartment of the motor vehicle. The air flow is arranged to circulate in the housing by a ventilation device controlled by the control means and comprising a support housing an electric motor driving the impeller in rotation. The support is mounted to the housing, and rotation of the impeller allows airflow to be drawn in from outside the housing and distributed within the housing. In this way, heat exchange takes place between the air flow and the heat exchanger, so...
