Definitions

  • the present disclosure relates to a fan module, and particularly to a fan module of a server or a computer.
  • 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.
  • 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.
  • FIG. 1 is an exploded, isometric view of a fan module in accordance with an embodiment.
  • FIG. 2 is similar to FIG. 1 , but viewed from a different aspect.
  • FIG. 3 is an enlarged view of a circled portion III of FIG. 2 .
  • FIG. 4 is an assembled, isometric view of the fan module of FIG. 1 .
  • FIG. 5 is an assembled, isometric view of the fan module of FIG. 2 .
  • FIG. 6 is a cross-sectional view of the fan module of FIG. 5 , taken along a line VI-VI of FIG. 5 .
  • FIGS. 1-3 show a fan module in accordance with an embodiment including a fan body 10 and a cover 20 .
  • 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 .
  • 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 .
  • 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 .
  • 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 .
  • FIG. 3 and FIG. 4 show the cover 20 , in assembly, is moved to align the hooks 25 with the mounting holes 1131 .
  • the cover 20 is pressed to the top plate 113 so that the hooks 25 are elastically deformed outwards by inner edges of the mounting holes 1131 so that the hooks 25 may insert into the mounting holes 1131 .
  • the sliding planes 2533 abut inner surfaces of the mounting holes 1131 , the latching portions 253 extend out of the mounting holes 1131 , and the hooks 25 rebound to engage with bottom edges of the mounting holes 1131 .
  • each latching plane 2531 abuts a bottom surface of the top plate 113 and is located between the top plate 113 and the bottom plate 115 , and each resisting portion 255 abuts the inner surface of the corresponding mounting hole 1131 .
  • the cover 20 is mounted to the top plate 113 .
  • the latching portion 253 is pulled outwards to elastically deform the hooks 25 until the hooks 25 disengage from the mounting holes 1131 .
  • the cover 20 is removed from the corresponding mounting hole 1131 .
