Abstract
A fan device includes a fan frame having an inner annular surface and a coupling groove, the inner annular surface defining a receiving space, and the coupling groove being recessed inward from the inner annular surface. The fan device also includes a fan blade assembly rotatably disposed within the fan frame and located in the receiving space. The fan device further includes a metal annular frame coupled to the coupling groove and positioned between the fan frame and the fan blade assembly. The fan frame includes a first annular engagement portion disposed in the coupling groove, and the metal annular frame includes a second annular engagement portion disposed on a side adjacent to the coupling groove. The metal annular frame surrounds the fan blade assembly and is mechanically retained within the coupling groove.

A fan device for electronic cooling systems, the fan device comprising:
- a fan frame having an inner annular surface and a coupling groove radially recessed inward from the inner annular surface towards a center of the fan device, the inner annular surface defining a receiving space;
- a fan blade assembly rotatably disposed within the fan frame and located in the receiving space;
- and
- a metal annular frame coupled to the coupling groove and positioned between the fan frame and the fan blade assembly,
- wherein:
- the fan frame includes a first annular engagement portion disposed in the coupling groove,
- the metal annular frame includes a second annular engagement portion disposed on a side adjacent to the coupling groove, and
- the metal annular frame surrounds the fan blade assembly and is mechanically retained within the coupling groove.
A method of assembling a fan device for electronic cooling systems, the method comprising:
- forming a fan frame having an inner annular surface and a coupling groove radially recessed inward from the inner annular surface towards a center of the fan device;
- forming a first annular engagement portion in the coupling groove;
- forming a fan blade assembly and rotatably mounting the fan blade assembly in a receiving space defined by the inner annular surface;
- forming a metal annular frame with a second annular engagement portion;
- and
- inserting the metal annular frame into the coupling groove such that the metal annular frame is positioned between the fan frame and the fan blade assembly,
- wherein the metal annular frame is mechanically retained within the coupling groove and surrounds the fan blade assembly.
