Description
- 1. Technical Field
- The present disclosure relates to a heat sink assembly.
- 2. Description of Related Art
- A traditional computer includes a heat sink assembled to a heat generating device to dissipate heat from the heat generating device. However, the heat sink is secured to the heat generating device by screws, making the installation process laborious and time-consuming.
- Many aspects of the embodiments can be better understood with references 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 embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
-
FIG. 1 is an exploded, isometric view of one embodiment of a heat sink assembly. -
FIG. 2 is the heat sink ofFIG. 1 viewed from another angle. -
FIG. 3 is an assembled view of the heat sink assembly ofFIG. 1 . -
FIG. 4 is a cross-sectional view ofFIG. 3 taken along line IV-IV. - The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. 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.”
-
FIGS. 1 and 2 show that a heat sink assembly, according to one embodiment, includes a printedcircuit board 10, a supportingframe 30, and aheat sink 50. - The printed
circuit board 10 includes aboard body 11 and aheat generating device 13 mounted to theboard body 11. Theboard body 11 defines a plurality of securingholes 15. - The supporting
frame 30 is made of metal. The supportingframe 30 includes a supportingframe body 31 and a plurality of securingportions 33, extending from the supportingframe body 31. The supportingframe body 31 defines anopening 310. The supportingframe body 31 includes asupport portion 311 and aflange 313 substantially perpendicularly extending from thesupport portion 311. Thesupport portion 311 is rectangular and is substantially parallel to theboard body 11. Thesupport portion 311 and theflange 313 surround theopening 310. The cross sections of thesupport portion 311 and theflange 313 are L-shaped taken along a plane substantially perpendicular to theboard body 11. - The
heat sink 50 includes abase 51 and a plurality offins 53 extending from thebase 51. Thefins 53 are substantially parallel to each other. Thebase 51 includes asoaking panel 511 and defines ahermetic space 513. Thesoaking panel 511 is located in thehermetic space 513. Thesoaking panel 511 includes apanel body 5111, a plurality ofprotrusions 5115 extending from thepanel body 5111, and a plurality ofmagnetic posts 5113 around the edges of thepanel body 5111 Themagnetic posts 5113 surround theprotrusions 5115. Theprotrusions 5115 prevent thepanel body 5111 from being deformed in assembly. -
FIGS. 3 and 4 show that in assembly, the securingportions 33 of the supportingframe 30 are aligned with the securingholes 15. The securingportions 33 pass through the securing holes to mount the supportingframe 30 to the printedcircuit board 10, such that theheat generating device 13 is received in theopening 310 of the supportingframe 30. Thebase 51 is placed on and magnetically adheres to thesupport portion 311 of the supportingframe 30 because of themagnetic posts 5113. This allows thepanel body 5111 to contact theheat generating device 13 and guide heat to thefins 53. Theflange 313 of the supportingframe 30 prevents theheat sink 50 from moving. - The
base 51 magnetically adheres to the supportingframe 30, easily securing theheat sink 50 to the supportingframe 30. In disassembly, theheat sink 50 is forcibly pulled to detach from the supportingframe 30. - 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 within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
