1. Technical Field
The disclosure relates to heat dissipation, and particularly to a fan assembly.
2. Description of Related Art
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.
Many aspects of the present embodiments can be better understood with reference to the following drawings. 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.
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.
Referring to
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.
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.
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).
Each resilient member 130 is a substantially T-shaped hollow rubber washer.

Referring to
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.
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.
