Abstract: A fan with improved self-cooling capability having a frame, a stator, a magnetic ring, an iron case, and a rotor blade impeller. The frame has a base for containing the stator, and the stator is provided with at least a coil. The magnetic ring is magnetically coupled to the stator, and the iron case is coupled to the magnetic ring while being provided with at least a first heat dissipation hole. The rotor blade impeller is formed on the iron case, in which at least a second heat dissipation hole aligned to the first heat dissipation hole is formed on a hub of the rotor blade impeller, and the first heat dissipation hole and the second heat dissipation hole are not formed to directly align to a position of the coil.

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.

Abstract: A fan device with increased airflow output is provided, which includes: a frame having an air inlet and an air outlet, and formed with an opening penetrating through the frame; and a rotating mechanism received in the opening of the frame and connected to a driving mechanism that drives the rotating mechanism to rotate, the rotating mechanism being composed of a hub and a plurality of blades peripherally mounted to the hub, wherein each of the blades is formed with at least an extending portion, and the extending portions are adapted to expose to the air inlet for increasing contact area between the blades and ambient air. By the above fan device with increased air intake, pressure and quantity of airflow outputted from the fan device can be desirably enhanced, so as to achieve optimal heat dissipation effect for an electronic device mounted with the fan device.

The frame has a base for containing the stator, and the stator is provided with at least a coil. The magnetic ring is coupled to the stator, and the iron case is coupled to the magnetic ring while being provided with at least a first heat dissipation hole adjacent to an outer edge of the iron case. The rotor blade impeller is formed on the iron case, in which at least a second heat dissipation hole aligned to the first heat dissipation hole is formed on a hub of the rotor blade impeller, and the first heat dissipation hole and the second heat dissipation hole are not formed directly above the end of the coil.
