1. Technical Field
The present disclosure relates to a fan module, and particularly to a fan module of a server or a computer.
2. Description of Related Art
Fan modules may be used for cooling electronic devices, such as computers. Many fan modules include a fan body and a cover or grill guards to prevent users from accidentally touching rotating fan blades and getting injured. However, the cover is secured to the fan body by screws, which are laborious and inconvenient to install. Therefore, an improved fan module is desired within the art.
Many aspects of the embodiments can be better understood with reference to the drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
The fan body 10 includes a cage 11 and a plurality of fan blades 13. The cage 11 includes a top plate 113 and a bottom plate 115 opposite to the top plate 113. The top plate 113 defines a receiving opening 112. The receiving opening 112 extends to the bottom plate 115 for receiving the plurality of fan blades 13. The top plate 113 defines four mounting holes 1131 in four corners of the top plate 113. In one embodiment, the top plate 113 and the bottom plate 115 are rectangular, and each of the four mounting holes 1131 is round.
The cover 20 includes four spokes 21 and a plurality of guards 23 connected to the four spokes 21. Each adjacent two of the four spokes 21 are substantially perpendicular to each other. Each of the four spokes 21 has an equal length. A hook 25 perpendicularly extends from an end of each of the four spokes 21. Each hook 25 includes a connecting portion 251, a latching portion 253, and a resisting portion 255. In one embodiment, a cross section of the connecting portion 251 is triangular. The latching portion 253 includes a latching plane 2531 and a sliding plane 2533 connected to the latching portion 253. The latching plane 2531 is connected to the sliding plane 2533 and located between a corresponding one of the spokes 21 and the sliding plane 2533. The resisting portion 255 is located between the corresponding spoke 21 and the latching plane 2531 and connected to the connecting portion 251. In one embodiment, the sliding planes 2533 are curved, and the resisting portions 255 have an arc-shaped profile, and each of the guards 23 is circular. The hooks 25 can be engaged in the mounting holes 1131.
In disassembly, the latching portion 253 is pulled outwards to elastically deform the hooks 25 until the hooks 25 disengage from the mounting holes 1131. Thus, the cover 20 is removed from the corresponding mounting hole 1131.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
