Description
- 1. Technical Field
- The present disclosure relates to a heat dissipation device.
- 2. Description of Related Art
- It is well known that a large amount of heat is often generated by an electronic component such as a central processing unit (CPU) of a computer. The heat must be quickly removed from the CPU to prevent unstable operation of or damage to the CPU. A heat sink is typically attached to the CPU to absorb the heat from the CPU. The heat absorbed by the heat sink is then dissipated to the air through a fan mounted to the heat sink. Typically, the fan is mounted to the heat sink through a plurality of fasteners extending through the fan and into the heat sink. It is cumbersome and inefficient to manipulate the fasteners when attaching or detaching the fan to or from the heat sink, and damage may occur to the fins of the heat sink.
- 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.

FIG. 1 is an exploded, isometric view of an exemplary embodiment of a heat dissipation device. -
FIG. 2 is a partially assembled, isometric view of the heat dissipation device ofFIG. 1 . -
FIG. 3 is an assembled, isometric view of the heat dissipation device ofFIG. 1 . - The disclosure, including the accompanying drawings, is illustrated by way of example 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

Thetop surface 322,bottom surface 324 andend walls 326 extend in the same direction. - The
top surface 322 includes two spaced extendingpieces 360. Aprotrusion 332 protrudes up from a distal end (opposite to the sidewall 320) of one of the extendingpieces 360. Afixing portion 334 defining a throughhole 336 therein extends from a distal end of the other extendingpiece 360. Eachend wall 326 includes aconnection piece 327 extending from thesidewall 320 and twofixing pieces 328 extending from opposite ends of theconnection piece 327. Twofixing holes 330 in alignment with each other are respectively defined in thefixing pieces 328 of eachend wall 326. Afixing portion 338 extends from a distal end of one of thefixing pieces 328 adjacent to thebottom surface 324 of aframe 32, and apin 350 extends from an inner side of thefixing portion 338. Acorresponding fixing piece 328 of theother end wall 326 adjacent to thebottom surface 324 of theframe 32 defines a throughhole 352 in the distal end of thefixing piece 328 for receiving thepin 350 of theother frame 32. - Each
fixing member 34 is made of elastic material, and includes a disc-shaped base 340, ashaft 344 extending from a side of thebase 340, and atapered blocking portion 342 formed on the circumference of theshaft 344 adjacent to thebase 340. - In assembling the
heat sink 20 to themotherboard 40, twofasteners 50 respectively extend through the through holes of theheat sink 20, and are received in the threaded holes of thecorresponding posts 42 of themotherboard 40, to fix theheat sink 20 to themotherboard 40. - In assembling the
rack 30 to theheat sink 20, fourfixing members 34 respectively extend through thefixing holes 330 of a first end of theframes 32 from an inner side of theframes 32, with the blockingportions 342 of thefixing members 34 extending out throughcorresponding fixing holes 330. Theframes 32 are then attached to theheat sink 20 from opposite sides of theheat sink 20, with thebottom surfaces 324 abutting the bottom of thebaseboard 22 of theheat sink 20 and theend walls 326 abutting opposite ends of theheat sink 20. Thepin 350 of oneframe 32 engages in the corresponding throughhole 352 of theother frame 32. Thetop surfaces 322 abut the top of theheat sink 20, with theprotrusion 332 of oneframe 32 received in thecorresponding slot 336 of theother frame 32. - Referring to
