Description

BACKGROUND

1. Technical Field
The present disclosure relates to a mounting apparatus for a fan.
2. Description of Related Art
With the continuing development of electronic technology, electronic devices, such as computers, generate more heat during operation than previously. The heat needs to be dissipated as quickly as possible. A common method for dissipating the heat is to use a fan to generate airflow to dissipate heat for a computer. Usually, the fan is mounded in a mounting apparatus to form a fan module to be mounted in the computer. However, different thicknesses of the fans need different mounting apparatuses, while there is no universal mounting apparatus.

The main wall 32 defines a vent portion (not labeled) in a center of the main wall 32. The main wall 32 defines two first locking holes 323 adjacent to the first sidewall 34 and two second locking holes 325 adjacent to the second sidewall 36. Each first locking hole 323 includes a wide portion 3232 extending to the first sidewall 34, and a narrow portion 3234 communicating with the wide portion 3232 and facing the second sidewall 36. Each second locking hole 325 includes a wide portion 3252 facing the first sidewall 34, and a narrow portion 3254 communicating with the wide portion 3252 and facing the second sidewall 36. The first sidewall 34 defines two spaced through holes 342. Two substantially L-shaped retaining portions 344 extend down from a distal end of the first sidewall 34, opposite to the first sidewall 34.
The locking member 40 includes two locking portions 42 and a wavy resilient portion 44 connected between the locking portions 42. Each locking portion 42 defines a substantially U-shaped through slot to form a resilient tongue portion 46. A limiting portion 462 protrudes on a distal end of each tongue portion 46. An operation portion 48 extends from each locking portion 42 adjacent to the resilient portion 44.
Referring to FIG. 3, in assembling the first fan 100, the fan 100 is received in the first mounting member 10, with two opposite lateral surfaces of the first fan 100 sandwiched between the side plates 14. The mounting posts 123 of the first mounting member 10 engage in the mounting holes 102 of one side of the first fan 100. The second mounting member 20 is attached to the other side of the first fan 100, with the other two opposite lateral surfaces of the first fan 100 sandwiched between the sidewalls 24 of the second mounting member 20. The blocks 144 of the side plates 14 of the first mounting member 10 engage in the cutouts 227 of the second mounting member 20 respectively. The hooks 142 of the side plates 14 of the first mounting member 10 are locked to the second sides 225 of the second mounting member 20. The mounting posts 223 of the second mounting member 20 engage in the mounting holes 102 of the other side of the first fan 100. Therefore the first fan 100 is fixed and sandwiched between the first and second mounting members 10 and 20.
When mounting the first mounting member 10 together with the first fan 100 to the bracket 30, the first latching portions 125 of the first mounting member 10 enter the wide portions 3232 of the first locking holes 323, and the second latching portions 127 of the first mounting member 10 enter the wide portions 3252 of the second locking holes 325. The first mounting member 10 is then moved down relative to the bracket 30, the first latching portions 125 engage in the narrow portions 3234 of the first locking holes 323, and the second latching portions 127 engage in the narrow portions 3254 of the second locking holes 325.
