One of the ribs includes a bottom wall (33), and first and second lateral walls (31, 32) extending from two opposite sides of the bottom wall, respectively. A receiving groove (35) is defined between the bottom wall and the lateral walls. A securing tab (40) extends from an outer end of the first lateral wall towards the second lateral wall. A securing finger (42) extends aslant from a free end of the tab towards the second lateral wall. A slot (50) is defined between the finger and the second lateral wall with a width thereof gradually decreased inwardly. The tab, the finger, the bottom wall and the first lateral wall cooperatively define a gap (45) therebetween for extension of power wires (60) of the fan.

    摘要: A heat dissipating fan includes a housing (201), a stator (21), a rotor (27) and a buffer structure. The housing defines an accommodating space (202) and includes a hollow tube (201b). The tube encloses first and second bearings (22, 23) therein. The stator is arranged in the accommodating space and around the tube. The rotor has a shaft rotatably disposed in the first and the second bearings. The buffer structure includes at least a pair of magnets (25, 26) received in the tube and located between the first and second bearings. Repellent force is generated between the magnets, thereby preventing at least one of the first and the second bearing from being damaged by an accidental force acting thereon.

    摘要: A cooling fan includes a fan housing (30) having a central tube (34) extending upwardly therefrom, a bearing (60) being received in the central tube, a stator (20) being mounted around the central tube, and a rotor (10) having a shaft (18) extending through the bearing. At least one notch (180, 184) is defined in an end of the shaft. A balance structure (62) is mounted around the shaft, and has a portion facing and surrounding an upper portion of the at least one notch of the shaft. The balance structure is made of magnetic material, which can attract the shaft downward to thereby counter the upward force generated by the rotor when it is driven to rotate. Accordingly, the noise problem incurred by the floating of the rotating rotor can be resolved by the present invention.
