Cooling fan assembly for electronic apparatus

摘要

A cooling fan assembly for an electronic apparatus includes a casing and first and second centrifugal fans for creating airflow through the casing to dissipate heat associated generated by the electronic apparatus. The casing has at least first and second air inlets and an air outlet. The first centrifugal fan is received in the casing and positioned proximate the air outlet, and the second centrifugal fan juxtaposed with the first centrifugal fan is also received in the casing and positioned proximate the air outlet and indirect fluid communication therewith. The first and second centrifugal fans and the casing further are configured such that the airflow is effectively induced to form a high-pressure volute tongue in a region bounded by the first and second centrifugal fans and the air outlet.
