Abstract
Description
- 1. Technical Field
- The disclosure generally relates to heat dissipating devices, especially to a heat sink cover and a heat dissipating device using the heat sink cover.
- 2. Description of Related Art
- Electronic devices in computers, such as central processing units (CPUs), generate a lot of heat during normal operation, which can deteriorate their operational stability, and damage associated electronic devices. Thus, the heat must be removed quickly to ensure normal operation of the CPU. Some heat dissipating devices include a heat sink mounted on a CPU to remove heat. Some heat sinks include a plurality of fins each having a corner projection. The corner projections may be hazardous during installation.
- Therefore there is a need for improvement in the art.
- 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 a heat dissipating device of an embodiment, the heat dissipating device including a heat sink and a heat sink cover. -
FIG. 2 is a partial enlarged, isometric view of the heat sink ofFIG. 1 , showing section II. -
FIG. 3 is a cross section view of the heat sink cover ofFIG. 1 , taken along line III-III. -

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
FIG. 1 , aheat dissipating device 10 includes aheat sink 30, aheat sink cover 40, and afan 50. - The
heat sink 30 includes abase 31, a plurality offins 32 extending radially from thebase 31, and foursecuring portions 33 extending from thebase 31. Each securingportion 33 includes afirst mounting portion 331 and asecond mounting portion 332. Thefirst mounting portion 331 includes afastener 3311 capable of securing theheat sink 30 to the motherboard. Thesecond mounting portion 332 defines a securinghole 3321. Eachfin 32 is generally rectangle-shaped. As shown inFIG. 2 , eachfin 32 includes afirst edge 321 and asecond edge 322 perpendicular to thefirst edge 321. Acorner projection 323 is corporately defined by thefirst edge 321 and thesecond edge 322. - The

Areceiving space 43 is corporately defined by the first wall and thesecond portion 42. The cross section of theheat sink cover 40 is L-shaped. Thefirst wall 41 includes fourmounting portions 411. Eachmounting portion 411 defines a throughhole 412 corresponding to thesecuring hole 3321 of theheat sink 30 and anopening 413 corresponding to thefastener 3311. Thesecond wall 42 has four receivingportions 422 for receiving thesecond mounting portions 332 respectively. Theheat sink cover 40 is circular and surrounds thecorner projections 323 of theheat sink 30. - Referring to
FIGS. 1 to 4 , in assembly of theheat dissipating device 10, theheat sink cover 40 is disposed on theheat sink 30 to cover thecorner projection 323 of theheat sink 30. The receivingportions 422 of theheat sink cover 40 receive thesecond mounting portions 332 of theheat sink 30 respectively. Theopenings 413 of theheat sink cover 40 align with thefirst mounting portions 331 of theheat sink 30 respectively. Thefirst wall 41 of the heat sink cover 40 contacts thefirst edge 321 of theheat sink 30 and thesecond wall 42 of the heat sink cover 40 contacts thesecond edges 322 of theheat sink 30. Thereceiving space 43 receives thecorner projections 323 of thefins 32. The securingholes 511 of thefan 50 are aligned with the throughholes 412 of theheat sink cover 40 respectively. Fourfasteners 60 are respectively extended through the securingholes 511 of thefan 50, the throughholes 412 of theheat sink cover 40, and then screwed into the securingholes 3321 of theheat sink 30 to secure thefan 50, theheat sink cover 40, and the heat sink 30 together. - Referring to
FIGS. 4 and 5 , a printedcircuit board 80 is placed in anenclosure 70. The printedcircuit board 80 includes aheat generating element 90 mounted thereon. The printedcircuit board 80 defines fourmounting holes 810 corresponding to thefasteners 3311 respectively. In assembly of theheat dissipating device 10 to theenclosure 70, thefasteners 3311 of theheat dissipating device 10 are aligned with and screwed into themounting holes 810 respectively to secure theheat dissipating device 10 in theenclosure 70. - It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of preferred embodiments, together with details of the structures and functions of the preferred 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.
