An electronic device includes a housing, a printed circuit board received in the housing, a plurality of heat-generating elements mounted on the printed circuit board and a heat dissipation device secured to an end of the housing. The heat dissipation device includes a fan module and a bracket securing the fan module onto the housing. The housing includes a first side wall and a second side wall with a passage defined therebetween. The heat-generating elements are positioned in the passage. The fan module includes first and second fans arranged side by side. The bracket defines first and second openings corresponding to the first and second fans respectively for air flow generated by the fans. An air baffle is pivotally connected to the bracket and capable of turning to close a corresponding opening corresponding to a failing fan upon failure of either the first or second fan. |
