Abstract
An enclosure for electronic equipment is disclosed having a series of vents arranged for ventilating the enclosure while minimizing flowing of spilled liquid into the enclosure through the vents. A series of vent pockets is formed in a side wall of the enclosure, extending downward from a top surface of the enclosure so that spilled liquid flows downward into the vent pockets. The vent pockets have a generally u-shaped configuration with an aperture extending through one of the side walls for ventilation. The apertures thus are formed in a plane substantially orthogonal to the top surface and the side wall of the enclosure. A liquid flow path through the vent pocket diverts the spilled liquid away from the aperture, so as to minimize flow of the liquid through the aperture into the enclosure. Another aspect of the invention is a low-cost method of making the enclosure by injection molding.
