Abstract
A fan frame for use with a fan is provided, which includes: a frame body having a top side and a bottom side opposed to the top side; an opening formed through the top and bottom sides of the frame body, allowing a plurality of blades of the fan to be received in the opening; and at least a recessed portion formed on the frame body at a position outside the opening and connected to the opening. By rotation of the blades of the fan, air is adapted to enter via the top side of the frame body into the opening directly and also through the recessed portion into the opening, so as to facilitate air intake and wind output for the fan as well as to improve heat dissipation efficiency as the fan is mounted to an electronic device.
