## Background
BACKGROUND
1. Technical Field
The present disclosure relates to mounting apparatuses and, more particularly, to a mounting apparatus for securing a fan in a computer system.
2. Description of Related Art
In a typical computer system, a plurality of fans is secured by screws or the like to a chassis of the computer system and used for producing a flow of cooling air over certain electrical components within the chassis, dissipating heat generated by the electrical components so that the components operate within a desired temperature range. When the fans are installed or removed from the chassis, a cover of the chassis should be removed to expose the fans to gain access with the proper tool. The installation or removal of the screws is time consuming and troublesome. In addition, during installation or removal of the screws, the computer system should be shut down which may be inconvenient.

DETAILED DESCRIPTION
Referring to FIGS. 1 and 2, an embodiment of a mounting apparatus is provided for mounting a fan 30 to a chassis 10 of a computer system. The mounting apparatus includes a frame 20 adapted to receive the fan 30, and two cushions 40, 42, which are configured to abut against opposite sides of the fan 30.
The chassis 10 defines an exhaust opening 16 in an end wall 14 thereof, for exhausting the hot air from the chassis 10. There is at least one power socket (not shown) mounted in the chassis 10.
The fan 30 includes an outlet 31, a power line 33, and a plug 35 connected to a free end of the power line 33. The plug 35 is adapted to be plugged in the power socket of the chassis 10 for electrically driving the fan 30. A pair of protrusions 37 is disposed at an outside surface of the fan 30. Each protrusion 37 defines a positioning hole 372.
The frame 20 includes a bottom wall 21, a pair of parallel sidewalls 22 perpendicularly extending from opposite edges of the bottom wall 21, and a venting plate 23 perpendicularly extending from another edge of the bottom wall 21 and substantially perpendicular to the sidewalls 22. A pair of positioning posts 27 perpendicularly extends from the bottom wall 21, and is adapted to be received in the positioning holes 372 of the protrusions 37 of the fan 30. The venting plate 23 defines a plurality of vents. Each of the sidewalls 22 includes an L-shaped locking plate 24 extending from an end thereof near the venting plate 23. Each of the locking plates 24 includes a pressing portion 241 with an end connected to the corresponding sidewall 22, and an operating portion 242 perpendicularly extending from another end of the pressing portion 241 far away from the corresponding sidewall 22. A wedged block 243 protrudes from an outside surface of each of the pressing portions 241. Each of the blocks 243 includes a stopping end perpendicular to the pressing portions 241 and a guiding slope slantingly extending from the pressing portions 241. Each of the operating portions 242 defines a receiving hole 244 adapted to allow a user's fingers to extend therein. A fixing portion 26 perpendicularly extends from another end of one of the sidewalls 22 far away from venting plate 23.
In assembly, the two cushions 40, 42 are respectively attached to inner surfaces of the two sidewalls 22 of the frame 20. The fan 30 is retained in the frame 20 by securing the positioning posts 27 in the positioning holes 372 of the protrusions 37 of the fan 30. The outlet 31 of the fan 30 aligns with the venting plate 23 of the frame 20. The cushions 40, 42 are sandwiched between the fan 30 and the corresponding sidewalls 22 of the frame 20 for shock absorption. The plug 35 is fixed in the fixing portion 26 and extends out of the frame 20.
Referring also to FIG. 3, to mount the frame 20 with the fan 30 retained therein in the chassis 10, the frame 20 is inserted into the chassis 10 via the exhaust opening 16. When the guiding slopes of the blocks 243 abut against edges of the end wall 14 of the chassis 10 at opposite sides of the opening 16, the pressing portions 241 of the locking plates 24 are urged to be deformed and move towards each other. When the frame 20 is fully received in the chassis 10, the venting plate 23 shields the exhaust opening 16 of the chassis 10 and the plug 35 is electrically coupled to the power socket in the chassis 10. At the same time, the pressing portions 241 restore, and the stopping ends of the blocks 243 abut against an inner surface of the end wall 14 of the chassis 10 beside the exhaust opening 16, therefore, the frame 20 is prevented from sliding out of the chassis 10, and the fan 30 is secured in the chassis 10.
To detach the frame 20 from the chassis 10, since the operating portion 242 is exposed in the exhaust opening 16 of the chassis 10, fingers can extend into the receiving holes 244 of the operating portions 242 of the locking plate 24 for driving the operating portions 24 to move toward each other. The pressing portions 241 are deformed and the blocks 243 disengage from the end wall 14 of the chassis 10, therefore, the frame 20 is capable of being drawn out of the chassis 10.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
