Patent ID: 8192180

Claim:
A heat dissipating fan comprising: a housing including an air inlet and an air outlet spaced from the air inlet in an axial direction, with an air passageway formed between the air inlet and the air outlet, with a fixed seat provided in the air passageway, with the fixed seat interconnected by a plurality of connecting members to the housing, with the fixed seat including a plurality of first positioning holes extending in the axial direction, with the fixed seat further including a through-hole extending in the axial direction; a first casing made of magnetically conductive material, with the first casing including a first outer wall having first and second ends, with a first annular lip extending outward from the first end of the first outer wall in a radial direction perpendicular to the axial direction, with the first annular lip including a plurality of second positioning holes aligned with the plurality of first positioning holes, with a plurality of fasteners extending through the plurality of first positioning holes and the plurality of second positioning holes with a first support located on the second end of the first outer wall; a second casing including a second outer wall having first and second ends, with a second annular lip extending outward from the first end of the second outer wall in the radial direction, with the second annular lip including a plurality of third positioning holes aligned with the plurality of first positioning holes and the plurality of second positioning holes, with the plurality of fasteners extending through the plurality of third positioning holes, with a second support located on the second end of the second outer wall, with the first annular lip of the first casing and the second annular lip of the second casing located on a same side of the fixed seat in the axial direction; and a motor mounted in the first and second casings, with the motor including a rotor, a stator, and a circuit board, with the rotor including a shaft and a magnetic element, with the shaft rotatably supported by the first and second supports, with an impeller coupled to the shaft, with the magnetic element aligned with the stator, with the circuit board electrically connected to the stator.
