Description:
BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The disclosure relates to heat dissipation, and particularly to a fan assembly. 
         [0003]    2. Description of Related Art 
         [0004]    Fans are often mounted in electronic devices with screws to dissipate heat. However, when servicing or replace the fans, the screws are inconvenient to unscrew.

The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present embodiments. Moreover, in the drawings, all the views are schematic, and like reference numerals designate corresponding parts throughout the several views. 
           [0006]      FIG. 1  is an isometric, exploded view of an embodiment of a fan assembly. 
           [0007]      FIG. 2  and  FIG. 3  are isometric, assembled views of the fan assembly of  FIG. 1 , showing different use states. 
       
    
    
     DETAILED DESCRIPTION 
       [0008]    The disclosure, including the accompanying drawings, is illustrated by way of examples and not by way of limitation. 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. 
         [0009]    Referring to  FIG. 1 , a fan assembly includes a fan holder  100 , and a fan  200  received in the fan holder  100 . 
         [0010]    The fan  200  includes a substantially rectangular first plate  210 , and a substantially rectangular second plate  220  opposite and substantially parallel to the first plate  210 . A first mounting hole  212  is defined in each corner of the first plate  210 . A second mounting hole  222  is defined in each corner of the second plate  220 . 
         [0011]    The holder  100  includes a first mounting member  110 , a second mounting member  120 , and a plurality of resilient members  130 . The first mounting member  110  is substantially L-shaped and includes a rectangular base wall  111  and a sidewall  112  substantially perpendicularly extending from a first side of the base wall  111 . A plurality of vents (not labeled in the figures) is defined in a center of the base wall  111 . A post  1112  extends from each corner of the base wall  111 . The base wall  111  includes a first flange  1113  extending from a second side of the base wall  111  opposite to the sidewall  112 , and two parallel second flanges  1114  respectively extending from a third and a fourth sides of the base wall  111  connected between the first and second sides. A first hook  1115  extends from a middle of the first flange  1113 . A substantially wedge-shaped protrusion  1116  protrudes from a distal of the first hook  1115 . Two substantially L-shaped second hooks  1117  extend from the first flange  1113 , at opposite sides of the first hook  1115 . Two locking slots  1118  are defined in base wall  111  adjacent to each second flange  1114 . A block  1119  protrudes from an inner surface bounding each locking slot  1118 . A through hole  1121  is defined in the sidewall  112  for mounting a cable connector for the fan  200 . Two poles  1122  extend from opposite sides of an upper portion of the sidewall  112 . 
         [0012]    The second mounting member  120  includes a base plate  121 . The base plate  121  includes a first end, a second end opposite to the first end, and two parallel sides. An end plate  122  extends from the second end of the base plate  121 . Two parallel side plates  124  extend from the parallel sides of the base plate  121 . A plurality of vents (not labeled) is defined in a center of the base plate  121 . Each corner of the base plate  121  defines a substantially U-shaped slot to form a tongue shaped resilient tab  1212 . A post  1214  extends from a distal end of each tab  1212 . The end plate  122  defines a first locking hole  1222  in a middle of the end plate  122 , and two second locking holes  1224  at opposite sides of the first locking hole  1222  respectively. Two spaced locking portions  1242  are formed on a side of each side plate  124  opposite to the base plate  121 . A pivot hole  1244  is defined in each side plate  124  adjacent to the first end of the base plate  121 . A holding portion  126  is formed at two opposite corners where the end plate  122  and the side plates  124  meet, for conveniently holding the fan holder  100 . A blocking portion  128  extends from each side plate  124  adjacent to each holding portion  126 , for fastening the fan holder  100  in an enclosure (not shown in the figures). 
         [0013]    Each resilient member  130  is a substantially T-shaped hollow rubber washer. 
         [0014]    Referring to  FIG. 2 , in assembly, the poles  1122  of the sidewalls  112  of the first mounting member  110  are respectively engaged in the pivot holes  1244  of the second mounting member  120 . The resilient members  130  are respectively set around the posts  1112  of the base wall  111 . 
         [0015]    Referring to  FIG. 3 , in use, the first plate  210  of the fan  200  is aligned with the first mounting member  110  of the fan holder  100 , the posts  1112  of the base wall  111  are engaged in the corresponding first mounting holes  212  of the fan  200 , with the resilient members  130  arranged between the first mounting holes  212  and the posts  1112 . 
         [0016]    The second mounting member  120  is pivoted to cover the first mounting member  110 . The posts  1214  of the second mounting member  120  engage in the corresponding second mounting holes  222  of the second plate  220  of the fan  200 . The protrusion  116  of the first hook  1115  of the first mounting member  110  is locked to the first locking hole  1222  of the second mounting member  120 . The second hooks  1117  of the first mounting member  110  are locked to the second locking holes  1224  of the second mounting member  120  respectively. The locking portions  1242  of the second mounting member  120  are engaged in the corresponding locking slots  1118  of the first mounting member  110  respectively, to be locked to the blocks  1119 . 
         [0017]    It is to be understood, however, that even though numerous characteristics and advantages of certain embodiments have been set forth in the foregoing description, 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 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.
