Abstract
Description
- 1. Technical Field
- The present disclosure relates to a heat sink assembly.
- 2. Description of Related Art
- The amount of heat generated from electronic components of computers has risen dramatically. A heat sink is usually mounted on an electronic component to remove heat generated by the component.
- A typical heat sink assembly is equipped with a mounting apparatus to fix the heat sink assembly on the electronic component. The mounting apparatus includes a bolt defining a groove therein, a spring retained around the bolt, and a fastener secured in the groove of the bolt to fix the mounting apparatus to the heat sink assembly. However, because the bolt often needs to be replaced to accommodate different electronic components, the fastener must be damaged to be removed from the bolt.
- Therefore, a heat sink assembly which overcomes the above-described deficiency is desired.
-
FIG. 1 is an exploded, isometric view of an embodiment of a heat sink assembly; -
FIG. 2 is an assembled, isometric view of the heat sink assembly ofFIG. 1 ; and - Referring to
FIG. 1 , an embodiment of a heat sink assembly includes aheat sink 10 and amounting apparatus 16. - The
heat sink 10 includes abase 11, which has abottom surface 113 configured to contact a heat source, and atop surface 115 on which a plurality offins 13 is formed. Thebase 11 defines astepped hole 14 in atop surface 115 of thebase 11. Thestepped hole 14 includes alarge hole 143 communicating with thetop surface 115, and asmall hole 145 communicating with thebottom surface 113 and thelarge hole 143. Thelarge hole 143 has a diameter greater than a diameter of thesmall hole 145. Accordingly, astep 141 is formed in thestepped hole 14 around thesmall hole 145. Acutout 15 is defined in an edge of thebase 11 communicating with thestepped hole 14. - The
mounting apparatus 16 is configured to be mounted in thestepped hole 14. Eachmounting apparatus 16 includes abolt 17 and aspring 18. Thebolt 17 includes ahead 171 at a top portion thereof, ashaft 172 at a middle portion thereof, and a threadedportion 175 at a bottom portion thereof. Agroove 173 is defined around a portion of theshaft 172, thereby forming anengaging portion 177, which is thinner than theshaft 172. Theengaging portion 177 has awide side 178 and anarrow side 179. The width of thewide side 178 is larger than the width of thecutout 15, and smaller than the diameter of thesmall hole 145. The width of thenarrow side 179 is smaller than the width of thecutout 15. A height of thegroove 173 is greater than a height of thestep 141 allowing for vertical movement of thebolt 17 in thestepped hole 14. - Referring to
FIG. 2 , thespring 18 is retained around theshaft 172 with a top end of thespring 18 resisting against thehead 171 of thebolt 17. Anarrow side 179 of theengaging portion 177 is aligned with thecutout 15. Thespring 18 is compressed to position the bottom end of thespring 18 above thetop surface 115 of the base. Then, theengaging portion 177 of thebolt 17 is moved into thestepped hole 14 by thenarrow side 179 of theengaging portion 177 passing through thecutout 15. Simultaneously, thestep 141 is engaged in thegroove 173 of thebolt 17 to limit thebolt 17 escaping from thegroove 173 in a vertical direction. Thespring 18 is then released. The bottom end of thespring 18 is inserted into thelarge hole 143 of thestepped hole 14, and resists against thestep 141. The edge of thelarge hole 143 limits thespring 18 to retain thebolt 17 in thestepped hole 14. Thebolt 17 is rotated in thestepped hole 14 to move thenarrow sides 179 out of alignment with thecutout 15. Thus, thebolt 17 cannot be unintentionally removed from thestepped hole 14, and themounting apparatus 16 is mounted to thebase 11 of theheat sink 10. - If the
mounting apparatus 16 needs to be detached from thebase 11, thebolt 17 is rotated in thestepped hole 14 to align thenarrow side 179 of theengaging portion 177 with thecutout 15. Thespring 18 is compressed until thespring 18 is removed from thelarge hole 143 of thestepped hole 14. Then, thebolt 17 is removed from thestepped hole 14 by thenarrow side 179 of theengaging portion 177 passing through thecutout 15. - It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function 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 to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
