Description
- 1. Technical Field
- The present disclosure relates to a heat dissipation device.
- 2. Description of Related Art
- With the continuing development of electronic technology, memories generate more heat during operation than previously. The heat should be dissipated as quickly as possible. In some cases, two metallic cooling fins are added to opposite sides of each memory to dissipate heat therefrom. However, this method makes maintenance difficult as it is inconvenient to disassemble the cooling fins.
- 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 similar toFIG. 1 , but viewed from another perspective. -
FIG. 3 is an assembled view of the heat dissipation device ofFIG. 1 . -
FIG. 4 shows a using state of the heat dissipation device ofFIG. 3 . -
FIG. 5 shows another using state of the heat dissipation device ofFIG. 3 . - The present disclosure, including the accompanying drawings, is illustrated by way of examples 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
FIGS. 1 and 2 , an exemplary embodiment of a heat dissipation device used to dissipate heat of a memory 100 (shown inFIGS. 4 and 5 ), includes aclamp 10, twofasteners 20, afirst cooling fin 30, and asecond cooling fin 40. - The
clamp 10 is substantially U-shaped, and includes a substantiallyrectangular top plate 12 and twolateral plates 14 extending down from opposite sides of thetop plate 12. Thetop plate 12 is convex in cross section, forming a shallow trough along the length thereof. A top of eachlateral plate 14 forms an arc-shaped connection portion 16 connected to the corresponding side of thetop plate 12, which is convenient to deform thelateral plates 14 relative to thetop plate 12. Two substantially L-shaped latches 140 substantially perpendicularly extend from opposite ends of a bottom of an outer surface of eachlateral plate 14. Eachlatch 140 and the correspondinglateral plate 14 bound aslot 142 along a length of thelateral plate 14. - Each
fastener 20 is made of elastic material, and includes a substantially U-shapedmain body 22 and twopivot pins 224 substantially perpendicularly extending from opposite distal ends of themain body 22. Themain body 22 includes a long resistingpole 220 and twoconnection poles 222 substantially perpendicularly extending up from opposite ends of the resistingpole 220. Eachpivot pin 224 substantially extends from a distal end of acorresponding connection pole 222 opposite to the resistingpole 220, away from theother connection pole 222. - The
first cooling fin 30 is substantially rectangular. Twofirst pivot tabs 32 substantially perpendicularly extend from opposite ends of a top side of thefirst cooling fin 30, facing thesecond cooling fin 40. Apivot pin 320 extends from an inner end of eachpivot tab 32, along a length of thefirst cooling fin 30 and toward theother pivot tab 32. Twoblocks 34 extend from an outer surface of thefirst cooling fin 30, away from thesecond cooling fin 40. Eachblock 34 defines apivot hole 340 extending along the length of thefirst cooling fin 30. - The
second cooling fin 40 is substantially rectangular. Two second pivot tabs 42 substantially perpendicularly extend from opposite ends of a top side of thesecond cooling fin 40, facing thefirst cooling fin 30. Eachsecond pivot tab 42 defines apivot hole 420 in an outer end of thesecond pivot tap 42, along a length of thesecond cooling fin 40 and opposite to the othersecond pivot tab 42. Twoblocks 44 extend from an outer surface of thesecond cooling fin 40, away from thefirst cooling fin 30. Eachblock 44 defines apivot hole 440 extending along the length of thesecond cooling fin 40. - Referring to
FIGS. 3 to 5 , in use, thefirst cooling fin 30 is attached to thesecond cooling fin 40, with thepivot pins 320 of thefirst cooling fin 30 rotatably engaged in thecorresponding pivot holes 420 of thesecond cooling fin 40, thereby pivotably mounting thefirst cooling fin 30 to thesecond cooling fin 40. Thememory 100 is positioned between thefirst cooling fin 30 and thesecond cooling fin 40, with opposite lateral surfaces of thememory 100 resisting against inner lateral surfaces of thefirst cooling fin 30 and thesecond cooling fin 40. Thelateral plates 14 of theclamp 10 are deformed away from each other by operating theconnection portions 16. The combined assembly of the first and second cooling fins 30 and 40 and thememory 100 is positioned between thelateral plates 14, with thetop plate 12 of theclamp 10 resisting against the first andsecond pivot tabs connection portions 16 are released, and thus thelateral plates 14 are restored to resist against the first and second cooling fins 30 and 40. Therefore, the combined assembly of the first and second cooling fins 30 and 40 and thememory 100 are firmly clamped by theclamp 10. Thepivot pins 224 of one of thefastener 20 correspondingly engage in thepivot holes 340 of thefirst cooling fin 30, and thepivot pins 224 of theother fastener 20 correspondingly engage in thepivot holes 440 of thesecond cooling fin 40. Thereby, thefasteners 20 are rotatably mounted to the first and second cooling fins 30 and 40, respectively. The resistingpoles 220 of thefasteners 20 resist against thelatches 140 of thelateral plates 14, by rotating thefasteners 20 to make the resistingpoles 220 latched in theslots 142 of thelatches 14, which makes theclamp 10 clamp the first andsecond fins memory 100. - In disassembly, the resisting
poles 220 of thefasteners 20 are deformed away from theslots 142 of thelateral plates 14. Theconnection portions 16 of thelateral plates 14 are deformed to move thelateral plates 14 away from each other. Therefore, theclamp 10 is readily to be removed, and then the first and second cooling fins 30 and 40 can be easily disassembled from thememory 100. - In this embodiment, the curvature of the
top plate 12 makes thetop plate 12 easily deformed and can guide thelateral plates 14 deformed along predetermined direction when thelateral plates 14 are deformed away from each other. - 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 present 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.
