ABSTRACT:
An enclosure (12) for electrical equipment (14) includes a fan mounted on an interior surface of the enclosure (12) and adapted to blow air outwardly from the enclosure (12) through a grille (24). The grille (24) includes a plurality of sets (90-96) of short, wide elongated slots, each set (90-96) having its slots disposed perpendicular to a radial direction of the fan hub (44) passing through the slots. The enclosure material between the slot sets (e.g. 90, 92) overlies struts (50) forming part of the support for the hub (44) carrying the fan blades. The construction provides low noise from air blown through the slots, while maintaining robust grille construction.
