Abstract
An exemplary electronic device includes a container, a fan assembly and a duct received in the container. The fan assembly includes a centrifugal fan and a fin group thermally contacting an electronic component in the container. An air passage is defined between each adjacent fins of the fin group. An inner side of the fin group is mounted on an outlet of the centrifugal fan. A bottom surface of the fin group and an inner surface of the container cooperatively define a first channel therebetween. The duct includes an inlet and a first outlet. Airflow guided by the centrifugal fan flows through the duct and the first channel to cool a bottom end of the fin group, then is absorbed into the centrifugal fan from an inlet of the centrifugal fan, and then flow through the air passages of the fin group to cool a central portion the fin group.
