- 2. Description of Related Art
- Generally, a heat dissipation device is provided to cool an electronic component of an electronic device. The heat dissipation device typically includes a heat sink attached to an outer surface of the electronic component, and a clip fastening the heat sink to the electronic device tightly.
- The clip includes a body spanning over and pressing the heat sink, and two clasps integrally formed at opposite ends of the body. When the heat sink is disposed onto the electronic device, one clasp engages with a hook of the electronic device firstly; then the other clasp is pushed downwardly by a tool until the other clasp is engaged with another hook of the electronic device. Thus, the heat sink is mounted on the electronic device. However, there are usually a plurality of electronic components arranged in the electronic device, and a space between adjacent electronic components is narrow. Therefore, operating the tool is inconvenient. Further, the tool and the clasp of the clip are prone to scrape the surrounding electronic components.
- What is needed, therefore, is a heat dissipation device having a clip to assemble the heat dissipation device to an electronic device easily and safely.

heat sink 10 is formed by extrusion of aluminum, and includes a solid, cubicalheat absorbing portion 11, fourelongated branches 13 extending outwardly from four upright edges of theheat absorbing portion 11, and a plurality offins 15. Theheat absorbing portion 11 thermally contacts theelectronic component 211 when theheat sink 10 is mounted on the PCB 200. A top end of theheat absorbing portion 11 defines two parallel and spacedgrooves 113 to receive theclip 30. A height of eachbranch 13 is equal to that of theheat absorbing portion 11. Top ends and bottom ends of thebranches 13 are coplanar with a top surface and a bottom surface of theheat absorbing portion 11, respectively. The outmost end of eachbranch 13 forms anelongated groove 133 extending along a longitudinal direction. Angles between each two adjoining twobranches 13 are equal. Thefins 15 extend outwardly from theheat absorbing portion 11 and thebranches 13. Thebranches 13 divide thefins 15 into four equal parts. Thefins 15 of each part are spaced and parallel to each other. Thefins 15 of any two opposite parts are parallel to each other. Thefins 15 of two adjoining parts are perpendicular to each other. Top portions of some of thefins 15 which are aligned with thegrooves 113 of theheat absorbing portion 11 are cut away, to avoidsuch fins 15 interfering with theclip 30. - Referring also to
FIGS. 4-6 , theclip 30 is made of a metallic sheet or a plastic sheet. Theclip 30 includes abody 31, a firstengaging member 33, a secondengaging member 35 and anoperating member 37. The first and secondengaging members 33, are located at opposite ends of thebody 31. Theoperating member 37 pivotally engages with the secondengaging member 35 and thebody 31. - The
body 31 has a generally V-shaped configuration, and includes two spaced, parallel, generally V-shaped arms 312, a first connectingplate 313 and a second connectingplate 314. The first and second connectingplates body 31, and are much shorter than thearms 312. The first and second connectingplates arms 312, respectively. Therefore, an opening 311 is defined between middle portions of thearms 312. Aslit 3141 is defined in a central portion of the second connectingplate 314, for engagingly receiving the secondengaging member 35. Afirst baffling portion 315 and asecond baffling portion 316 extend downwardly from front and rear edges of the second connectingplate 314. The secondengaging member 35 is located between, and perpendicular to, thefirst baffling portion 315 and thesecond baffling portion 316. Twoelongated mounting plates 317 extend upwardly from opposite lateral edges of the second connectingplate 314, respectively, to pivotally engage with theoperating member 37. A central portion of themounting plate 317 defines a throughhole 3171 therein. - The first
engaging member 33 is a rectangular sheet, and extends downwardly from an outer end of the first connectingplate 313. A top portion of the firstengaging member 33 is smaller than a bottom portion of the firstengaging member 33. Ahole 331 is defined in the bottom portion of the firstengaging member 33, for engagingly receiving one of theclasps 305 of thechassis 300. - The second engaging
member 35 includes atop portion 353 and abottom portion 351. Thebottom portion 351 is elongated and defines a rectangular throughhole 3513 therein. A width of thebottom portion 351 is larger than that of theslit 3141 of the second connectingplate 314. Thetop portion 353 extends upwardly from a right side of a top end of thebottom portion 351. Thetop portion 353 is narrower than theslit 3141 of the second connectingplate 314. A throughhole 3531 is defined at a middle of thetop portion 353. - The operating
member 37 includes a cam-shaped connectingportion 370, and ahandle 374 extending from an end of the connectingportion 370. Aslot 371 extends inwards from the connectingportion 370 to a middle of thehandle 374 along a longitudinal direction of the operatingmember 37, to receive thetop portion 353 of the second engagingmember 35 therein. Twoshafts 373 extend outwardly from a bottom end of two lateral sides of the connectingportion 370, corresponding to the throughholes 3171 of the mountingplates 317 of thebody 31. Two throughholes 375 are defined at a top end of the lateral sides of the connectingportion 370. - When the
clip 30 is assembled, the connectingportion 370 of the operatingmember 37 is sandwiched between the mountingplates 317 of thebody 31, with theshafts 373 respectively engaging in the throughholes 3171 of the mountingplates 317. Thus, the operatingmember 37 is assembled to thebody 31. Theshafts 373 are rotatable relative to the mountingplates 317. Thetop portion 353 of the second engagingmember 35 extends through theslit 3141 of the second connectingplate 314 of thebody 31 and theslot 371 of the operatingmember 37 from bottom to top. Abolt 38 extends through one of the throughholes 375, the throughhole 3531 of thetop portion 353 of the second engagingmember 35, and the other throughhole 375 of the operatingmember 37 in that order, to assemble the second engagingmember 35 to thebody 31. Thus, theclip 30 is assembled completely. Thetop portion 353 of the second engagingmember 35 protrudes up beyond the operatingmember 37. A bore diameter of the throughhole 3531 is larger than a diameter of thebolt 38. A width of each of theslot 371 and theslit 3141 is larger than a thickness of thetop portion 353 of the second engagingmember 35. Thus, the second engagingmember 53 may be slidable along thebolt 38 when thetop portion 353 is operated. - The
fan 50 includes aframe 51, and animpeller 53 received in theframe 51. An aperture is defined in each corner of theframe 51, for assembling thefan 50 to theheat sink 10. When assembled, thefan 50 is arranged on theheat sink 10, such that the apertures are aligned with theelongated grooves 133 of theheat sink 10, respectively. Thenbolts 55 are extended through the apertures to engage in theelongated grooves 133 and thereby fix thefan 50 on theheat sink 10. - When the
heat dissipation 100 is assembled, theheat sink 10 is arranged on thechassis 300 and contacts theelectronic component 211. Thebody 31 of theclip 30 spans over theheat sink 10, with the first and second connectingplates heat sink 10. The middle portions of thearms 312 of thebody 31 are received in thegrooves 113 of theheat absorbing portion 11 of theheat sink 10. The operatingmember 37 is raised to make the first engagingmember 33 move to acorresponding clasp 305 of thechassis 300 until theclasp 305 enters thehole 331 of the first engagingmember 33. Then, the operatingmember 37 is released and thetop portion 353 of the second engagingmember 35 is pressed to make the second engagingmember 35 move downwardly and outwardly until the throughhole 3513 of thebottom portion 351 is aligned with another correspondingclasp 305 of thechassis 300. Then, thetop portion 353 is pushed to make thebottom portion 351 move horizontally towards thechassis 300 until thebottom portion 351 clasps theclasp 305. The operatingmember 37 is then rotated relative to theheat sink 10 to drive the second engagingmember 35 to move upwardly until the operatingmember 37 is locked. In this state, a top end of thebottom portion 351 of the second engagingmember 35 abuts against a bottom surface of the second connectingplate 314. Then, thefan 50 is mounted on the top end of theheat sink 10. Thus, theheat dissipation 100 is assembled to theelectronic component 211 tightly. - In this embodiment, the
top portion 353 of the second engagingmember 35 is operated to make thebottom portion 353 of the second engagingmember 35 clasp theclasp 305 or to disengage from theclasp 305. Therefore, a tool is not needed for assembly or disassembly of the heat dissipation device. Accordingly, the risk of scraping of other components (not shown) on thePCB 200 is reduced or even eliminated altogether. - It is to be understood, however, that even though numerous characteristics and advantages of various 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.
