Gehäusekomponente für eine zu belüftende Einrichtung

摘要

The invention relates to a housing component for a device to be ventilated, in particular an electrical or electronic device such as a mains piece with a planar wall section and a perforated aperture in the wall section. The aperture comprises several openings and webs between the openings. The webs are at least partly displaced relative to the surface of the wall section and preferably curved and thus elongated such that the total area of the openings defined by the webs is increased. The flow resistance of the perforated aperture, which is determined by the proportion of free surface to the base area of the aperture, is thus reduced.
