US 2003/0156350 A1 · Disc drive housing with air guide

Abstract

The present invention relates to an air guide for use in a disc drive such that air flow can be redirected to improve the efficiency of a filter located within the disc drive. Embodiments of the present invention provide for an air guide having air guide surfaces that, in conjunction with sides of the disc drive housing, are configured to channel air flow off a spinning disc, through a filter, and back into the mainstream air flow. The air guide may be formed as an integral unit with either the inner major surface of the cover or of the baseplate, or both, such that the air guide may extend over part of the disc surface and provide an effective channel for air flow without the need for additional assembly processes during manufacture.
