Abstract
Description
- 1. Technical Field
- The present invention relates generally to heat dissipation devices, and more particularly to a clip assembly which can conveniently mount a heat sink to an electronic component.
- 2. Description of Related Art
- It is widely acknowledged that heat is produced during operations of electronic components such as processors of computers. Therefore, a heat dissipation device such as a heat sink is needed for heat dissipation of the electronic component. In order to keep the heat sink into an intimate contact with the electronic component, a clip such as a retainer or a fastener is generally required. However, the conventional clip needs a special tool during mounting or dismounting of the heat sink, which is not appreciated by users or operators.
- Therefore, it is desirable to provide a clip assembly to overcome the above-mentioned shortcoming.
- 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, like reference numerals designate corresponding parts throughout the several views.

FIG. 1 is an isometric view of a heat dissipation device to be mounted on a printed circuit board according to a first embodiment of the present invention. -
FIG. 2 is a cross-sectional view of the heat dissipation device ofFIG. 1 , taken along line II-II thereof. -
FIG. 3 is a cross-sectional view of the heat dissipation device ofFIG. 1 , taken along line III-III thereof. -
FIG. 4 is an isometric view of a positioning member of a clip assembly of the heat dissipation device ofFIG. 1 . - Referring to
FIG. 1 , aheat dissipation device 1 according to an exemplary embodiment of the present invention includes aheat sink 11 and aclip assembly 10. Theheat sink 11 is mounted on anelectronic component 30 which is mounted on a printedcircuit board 20 by theclip assembly 10. Theheat sink 11 includes abase 111 and a plurality of pin-shaped fins 112 extending upwardly and perpendicularly from thebase 111. The plurality offins 112 are arranged on thebase 111 in rows and columns, thereby defining a plurality oflateral air channels 118 between two adjacent rows offins 112 and a plurality oflongitudinal air channels 119 between two adjacent columns offins 112, wherein the plurality oflongitudinal air channels 119 are perpendicular to the plurality oflateral air channels 118. - Referring to
FIGS. 2-3 , two adjacent columns of thefins 112 are located at a center of thebase 111 and oppositely disposed at two lateral sides of thelongitudinal air channel 119 a in a center of thebase 111. Twocentral fins 112 a, 112 b at the two adjacent columns of thefins 112 form two opposite triangle-shaped hooks 115, respectively, and thehooks 115 are located above and adjacent to thebase 111. The twocentral fins 112 a, 112 b have a larger width than each of theother fins 112. Thehook 115 extends from a lateral surface of thefin 112 a (112 b) into thelongitudinal air channel 119 a. Each of the twohooks 115 includes a sloping guiding surface 116 extending downwardly and inwardly from thefin 112 a (112 b) and a step 117 formed at a bottom of thehook 115. Thehooks 115 extend from thefins 112 a, 112 b toward each other. - The
clip assembly 10 includes a Z-shaped wire clip 12 and a W-shaped positioning member 13. Thewire clip 12 is made of a resilient material such that when it is twisted it produces a torsional spring-bias force tending to return to an original shape. Thewire clip 12 is a bent wire and includes a longitudinal resistingportion 121, afirst clipping arm 122 and asecond clipping arm 123. Thefirst clipping arm 122 and thesecond clipping arm 123 are perpendicular to the resistingportion 121 and extend from two opposite ends of the resistingportion 121 in opposing directions. The resistingportion 121 forms aprotrusion 124 by bending a center of the resistingportion 121. A lateral width of thepositioning member 13 in a natural state is larger than a width of a gap 130 between thehooks 115. Each of thefirst clipping arm 122 and thesecond clipping arm 123 forms acatch 125 at a free end thereof. - Referring to
FIG. 4 , thepositioning member 13 includes asemi-circular seat 131 and two positioningarms 132 symmetrically disposed at two opposite lateral sides of theseat 131. Asemi-circular receiving groove 134 is defined under theseat 131 for receiving the resistingportion 121 of thewire clip 12 therein. Apositioning slot 135 is defined through a central portion of theseat 131 corresponding to theprotrusion 124 of thewire clip 12. Thus, theseat 131 has a C-shapedfront tab 136 and a C-shapedrear tab 137 formed at two longitudinal ends of thepositioning slot 135 for abutting on the resistingportion 121 of thewire clip 12. The two positioningarms 132 extend upwardly and outwardly from the two lateral sides of theseat 131. Twofingers 138 extend laterally and outwardly from two longitudinal sides of a top of each of the two positioningarms 132, respectively. - When the
heat dissipation device 1 is pre-assembled, the resistingportion 121 of thewire clip 12 is received in the receivinggroove 134 and theprotrusion 124 of thewire clip 12 is inserted into thepositioning slot 135 of thepositioning member 13. Thepositioning member 13 is placed in thelongitudinal air channel 119 a and the resistingportion 121 is oriented substantially parallel to thelongitudinal air channel 119 a. Then, the positioningmember 13 is pushed downwardly together with thewire clip 12 to cause the positioningarms 132 to move downwardly. The guiding surfaces 116 of thehooks 115 guide the positioningarms 132 of thepositioning member 13 to slide downwardly. The positioningarms 132 are brought into interaction with the guiding surfaces 116 to cause the positioningarms 132 to contract inwardly toward each other. - Once the positioning
arms 132 have passed through the gap 130 between the twohooks 115, the positioningarms 132 elastically restore back to their original state. The two positioningarms 132 laterally resist on the twofins 112 a, 112 b, respectively, whereby thepositioning member 13 is laterally sandwiched between the twofins 112 a, 112 b. Each of the two positioningarms 132 is vertically sandwiched between thebase 111 and acorresponding hook 115 of one of the twofins 112 a, 112 b whereby thepositioning member 13 is vertically sandwiched between thehooks 115 and thebase 111. Thefin 112 a (112 b) is longitudinally sandwiched between the twofingers 138 of acorresponding positioning arm 132. The resistingportion 121 of thewire clip 12 rests on theheat sink 11 and is received in thereceiving groove 134 of theseat 131 whereby thewire clip 12 is vertically sandwiched between theseat 131 and thebase 111. A blockage of theprotrusion 124 by thefront tab 136 and therear tab 137 prevents thewire clip 12 from moving along a longitudinal direction of the resistingportion 121 of thewire clip 12. - In assembly of the
heat dissipation device 1 onto the printed circuit board 20 (PCB) having theelectronic component 30 thereon, thebase 111 of theheat sink 11 is placed on theelectronic component 30. Then, thefirst clipping arm 122 is clockwise rotated and thesecond clipping arm 123 is anti-clockwise rotated whereby thecatches 125 of thefirst clipping arm 122 and thesecond clipping arm 123 are engaged with afirst tab 21 and a second tab 22 of thePCB 20, respectively. A resilient deformation of thewire clip 12 causes the resistingportion 121 of thewire clip 12 to press downwardly thebase 111 of theheat sink 11. Therefore, theheat dissipation device 1 is easily and firmly fixed on theelectronic component 30 of thePCB 20. Thus, heat generated by theelectronic component 30 can be effectively transferred to theheat sink 11. - It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
