An electronic device includes a first housing with a first air inlet and outlet, a heat dissipation assembly, and a filter structure between the first housing and the heat dissipation assembly. The heat dissipation assembly defines a second air inlet and outlet. The first air inlet, the second air inlet, the second air outlet and the first air outlet communicate with each other. The heat dissipation assembly draws air across itself from the two air inlets, and expels the air from the two air outlets. The filter structure covers the second air inlet and defines a plurality of very small holes which function to filter dust out from the incoming air.

Electronic device

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.

An electronic device includes a casing, a fan, and a heat sink. The casing defines a plurality of through holes therein. The fan defines air outlet at one side thereof facing the through holes of the casing. The air outlet includes a first portion and a second portion. Air pressure in the first portion is larger than air pressure of the second portion. The heat sink includes a first fin set arranged on the first portion and a second fin set arranged on the second portion. A first passage is defined between each two neighboring first fins. A second passage is defined between each two neighboring second fins. A width of the second passage is less than that of the first passage.
