摘要

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).
