Abstract
Systems and methods for Venturi fan-assisted cooling of electrical equipment are provided. In one embodiment, a cooling unit for an enclosure housing electronics is provided. The cooling unit comprises: a fan shroud having at least one electrical fan; and a Venturi chamber having a first inlet for receiving a heated airflow from a heatsink, a second inlet for receiving an airflow from a surrounding environment, and an outlet coupled to the fan shroud, the fan drawing air from the Venturi chamber via the outlet when the fan is on. The Venturi chamber comprises a wall for directing the airflow air from the surrounding environment in from the second inlet and across the heated airflow from the heatsink in a manner to as to draw the heated airflow through the heatsink using a Venturi effect, when the fan is on.
