A heat sink assembly includes a fixing plate, a heat sink, a number of first fasteners, and a second fastener. The fixing plate includes a number of first poles and a second pole extending from a top of the fixing plate. A first threaded hole is defined in a top of each first pole, and a first threaded portion is formed on a top of the second pole. The heat sink includes a base. The first and second fasteners are extended through the base. A second threaded portion is formed on a bottom of each first fastener, and engages in a corresponding one of the first threaded holes. A second threaded hole is defined in a bottom of the second fastener, and engages with the first threaded portion. The second pole and the second fastener can limit the heat sink fixed to the fixing plate to only one angle.
Description
- 1. Technical Field
- The present disclosure relates to a heat sink assembly.
- 2. Description of Related Art
- To fasten a heat sink having a number of through holes to a motherboard, a fixing plate defining a number of threaded holes is first mounted to the motherboard. Then, a number of screws are respectively extended through the through holes and are engaged in threaded holes, to fix the heat sink to the fixing plate. The heat sink always needs to be fixed to the fixing plate at a predetermined angle. However, the through holes are always symmetrically arranged on the heat sink around a center of the heat sink, and the heat sink can be fixed to the fixing plate in multiple angles. If there is no mistake-proof design, the heat sink may be easily fixed to the fixing plate at an error angle.
- 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 drawing, 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 sink assembly. -
FIG. 2 is similar toFIG. 1 , but viewed from another perspective. -
FIG. 3 is an assembled, isometric view ofFIG. 2 . - 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.
-
FIGS. 1 and 2 , are exemplary embodiments of a heat sink assembly including afixing plate 10, threefirst fasteners 20, asecond fastener 30, foursprings 40, four substantially C-shaped tabs 50, and aheat sink 60. - The
heat sink 60 includes asquare base 61, and a plurality offins 63 extending up from thebase 61. Four through holes (not shown) are defined in thebase 61, respectively adjacent to four corners of thebase 61. The through holes are symmetrically arranged around a center of thebase 61. - The
fixing plate 10 is square shaped. Threefirst poles 12 perpendicularly extend up from thefixing plate 10, respectively adjacent to three corners of thefixing plate 10. Asecond pole 14 perpendicularly extends up from thefixing plate 10, adjacent to the last corner of thefixing plate 10. Thefirst poles 12 and thesecond pole 14 are symmetrically arranged around a center of thefixing plate 10. A first threadedhole 121 is defined in the top of eachfirst pole 12. Thesecond pole 14 includes apost 141 and a first threadedportion 143 extending up from the top of thepost 141. Thefixing plate 10 is mounted to a motherboard (not shown) at a predetermined angle. - Each
first fastener 20 includes ahead 21, apost 23 perpendicularly extending down from the bottom of thehead 21, and a second threadedportion 25 extending down from the bottom of thepost 23. Acircular slot 231 is defined in a circumference of thepost 23 adjacent to the second threadedportion 25. Threesprings 40 are respectively placed around theposts 23. The second threadedportions 25 and lower sections of theposts 23 respectively extend through three predetermined through holes of thebase 61, to allow threetabs 50 to engage in theslots 231 under thebase 61. Thesprings 40 are respectively sandwiched between thebase 61 and thecorresponding heads 21. Thetabs 50 engage with the bottom of thebase 61. - The
second fastener 30 includes ahead 31, and apost 33 perpendicularly extending down from the bottom of thehead 31. A second threadedhole 331 is defined in the bottom of thepost 33. Acircular slot 333 is defined in a circumference of thepost 33 adjacent to the bottom of thepost 33. Thelast spring 40 is placed around thepost 33. A lower section of thepost 33 is extended through the last through hole of thebase 61, to allow thelast tab 50 to engage in theslot 333 under thebase 61. Thelast spring 40 is sandwiched between thebase 61 and thehead 31. Thelast tab 50 engages with the bottom of thebase 61. -
FIG. 3 , in assembly, theheat sink 60 is placed above thefixing plate 10, to allow thesecond fastener 30 to align with thesecond pole 14, and to allow thefirst fasteners 20 to respectively align with thefirst poles 12. The first andsecond fasteners portions 25 to respectively engage in the first threadedholes 121, and to allow the first threadedportion 143 to engage in the second threadedhole 331. Thereby, theheat sink 60 is fastened to thefixing plate 10 at a right angle. In the embodiment, thesecond pole 14 and thesecond fastener 30 can limit theheat sink 60 fastening to thefixing plate 10 at only one angle, which can prevent angle mistake in assembly of theheat sink 60. - Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and the functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
