Abstract

A compact dual redundant cooling fan assembly has an outboard cooling fan, a turbulent to laminar flow modification element, and an inboard cooling fan mounted in a series configuration. A connecting sleeve directs the combined output into a cabinet containing components to be cooled. A sliding drawer within the connecting sleeve detachably holds said outboard cooling fan, said flow modification element, and said inboard cooling fan, allowing for the hot swappable replacement of defective components. A controller is in communication with a power source, said outboard fan, said inboard fan, and at least one sensor monitoring the status of each of said outboard cooling fan and said inboard cooling fan. Said controller is configured to maintain said combined output above a minimum control level at all times, regardless of the failure of said outboard fan or said inboard fan.
