Description
- 1. Technical Field
- The present disclosure generally relates to heat dissipation devices, and particularly to a heat dissipation device for dissipating heat of an electronic component.
- 2. Description of Related Art
- With the continuing development of electronics technology, electronic components, such as CPUs (central processing units) and others, generate more heat in operation than previously. The heat is required to be dissipated immediately. Conventionally, metallic heat sinks are mounted on electronic components to dissipate heat therefrom.
- A typical heat sink includes a base, and a plurality of heat dissipation fins extending upward from the base. A heat dissipation efficiency of the heat sink depends on the size of the heat sink. A heat sink with a large size generally has a high heat dissipation efficiency. However, when a large heat sink is mounted on the electronic component, it may interfere with the nearby components. This situation occurs more often in small sized electronic devices, such as in a server rack unit of a server system, or a notebook computer. A heat sink with a small size may not interfere with other components, but the heat dissipation efficiency may not properly satisfy the heat dissipation requirements of the electronic component.
- For at least these reasons, a heat dissipation device which can overcome the described limitations is desired.
- Many aspects of the 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 placed upon clearly illustrating the principles of the present disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

FIG. 1 is an isometric, assembled view of a heat dissipation device according to a first embodiment of the present disclosure. -
FIG. 2 is an exploded view of the heat dissipation device ofFIG. 1 . -
FIG. 3 is a side view of an example of an application of the heat dissipation device ofFIG. 1 . -
FIG. 4 is a side view of a heat dissipation device according to a second embodiment of the present disclosure, shown in an exemplary application. - Referring to
FIGS. 1 and 2 , aheat dissipation device 100 according to a first embodiment of the present disclosure is shown. Theheat dissipation device 100 includes afirst heat sink 10, and asecond heat sink 20 detachably mounted to a lateral side of thefirst heat sink 10 with twodetachable fasteners 30. - The
first heat sink 10 and thesecond heat sink 20 are made of heat conductive material, such as aluminum or aluminum alloy. Thefirst heat sink 10 and thesecond heat sink 20 can be manufactured through aluminum extrusion or through fin soldering. In this embodiment, thefirst heat sink 10 and thesecond heat sink 20 are manufactured through aluminum extrusion. Thefasteners 30 can be any kind of detachable fasteners, such as bolts with nuts, threaded screws, etc. In the illustrated embodiment, thefasteners 30 are threaded screws threadedly engaged in thefirst heat sink 10. - The
first heat sink 10 includes afirst base plate 11, and a number of firstheat dissipation fins 12 formed on thefirst base plate 11. Thefirst base plate 11 includes a firstfin disposition section 112, and a first connectingsection 111 beside the firstfin disposition section 112. The first heat dissipation fins 12 extend upward from the firstfin disposition section 112 of thefirst base plate 11, and are all parallel to one another. The first connectingsection 111 is without fins formed thereon, and defines two throughholes 1111 therein. A bottom surface of thefirst base plate 11 is configured for attaching with an electronic component 40 (seeFIG. 3 ). - The
second heat sink 20 has a size smaller than that of thefirst heat sink 10. Thesecond heat sink 20 includes asecond base plate 21, and a number of secondheat dissipation fins 22 formed on thesecond base plate 21. Thesecond base plate 21 includes a secondfin disposition section 212, and a second connectingsection 211 beside the secondfin disposition section 212. The second heat dissipation fins 22 extend upward from the secondfin disposition section 212 of thesecond base plate 21, and are all parallel to one another. The second connectingsection 211 is bare without fins, and defines twomounting holes 2111 therein corresponding to the throughholes 1111 of thefirst heat sink 10. Each of the first andsecond base plates second base plate 21 is equal to that of thefirst base plate 11. A width of thesecond base plate 21 is less than that of thefirst base plate 11. A height of the second heat dissipation fins 22 extending above the secondfin disposition section 212 is less than that of the first heat dissipation fins 12 extending above the firstfin disposition section 112. A length of each secondheat dissipation fin 22 is equal to that of each firstheat dissipation fin 12. - When the
second heat sink 20 is assembled on thefirst heat sink 10, the second connectingsection 211 of thesecond heat sink 20 is superposed on the first connectingsection 112 of thefirst heat sink 10, with themounting holes 2111 of the second connectingsection 211 respectively aligned with the throughholes 1111 of the first connectingsection 111. Twofasteners 30 are extended through themounting holes 2111 and the throughholes 1111, and thereby thesecond heat sink 20 is mounted to thefirst heat sink 10. In the illustrated embodiment, the first heat dissipation fins 12 are parallel to the second heat dissipation fins 22. The firstheat dissipation fins 12 define a first top face (not labeled), the second heat dissipation fins 22 define a second top face (not labeled), and the second top face is lower than the first top face. To achieve a close contact between the second connectingsection 211 of thesecond heat sink 20 and the first connectingsection 111 of thefirst heat sink 10, a layer of thermal interface material, such as heat conductive silicon grease, can be disposed between the second connectingsection 211 of thesecond heat sink 20 and the first connectingsection 111 of thefirst heat sink 10. - Referring to
FIG. 3 , when theheat dissipation device 100 is used to dissipate heat of theelectronic component 40 on acircuit board 50, thefirst base plate 11 of thefirst heat sink 10 of theheat dissipation device 100 is attached on theelectronic component 40. The heat generated by theelectronic component 40 is transferred to thefirst heat sink 10. A portion of the heat is directly dissipated through thefirst heat sink 10, and another portion of the heat is transferred to thesecond heat sink 20 through the first and second connectingsections second heat sink 20. - Since the
second heat sink 20 has a smaller size than thefirst heat sink 10 and can be detachably connected to the lateral side of thefirst heat sink 10, thesecond heat sink 20 is available to be mounted to thefirst heat sink 10 in certain environments in which theheat dissipation device 100 may be applied. In the example illustrated inFIG. 3 , a heat sink wider than thefirst heat sink 10 cannot be used, because it would interfere with thecomponents electronic component 40. Yet thesecond heat sink 20 is able to be accommodated in the limited free space available nearby thecomponents second heat sink 20 can be utilized to supplement the heat dissipation capability of thefirst heat sink 10. In this kind of application, theheat dissipation device 100 has high heat dissipation efficiency, yet with little or no risk of interfering with thecomponents electronic component 40. Furthermore, the low profile of thefirst heat sink 10 is not exceeded by thesecond heat sink 20. - In addition, the
heat dissipation device 100 can also resolve a heat sink redesign problem that may be caused by an upgrading of theelectronic component 40. For example, originally, a heat dissipation efficiency of thefirst heat sink 10 is designed to satisfy a heat dissipation requirement of theelectronic component 40, and thefirst heat sink 10 alone is mounted on theelectronic component 40 to dissipate the heat of theelectronic component 40. When theelectronic component 40 is upgraded to have a higher power, a redesign or upgrade of thefirst heat sink 10 may not be necessary. This is because thesecond heat sink 20 can be attached to thefirst heat sink 10 to satisfy the added heat dissipation requirement of the upgradedelectronic component 40. Furthermore, thesecond heat sink 20 can be manufactured through a simple procedure, such as aluminum extrusion, thus minimizing a cost of theheat dissipation device 100. - To further promote the heat dissipation efficiency of the
heat dissipation device 100, two or moresecond heat sinks 20 can be mounted to thefirst heat sink 10.FIG. 4 shows aheat dissipation device 100 a according to a second embodiment of the present disclosure. Theheat dissipation device 100 a includes afirst heat sink 10 a, and twosecond heat sinks 20 detachably mounted at two opposite lateral sides of thefirst heat sink 10, respectively. - It is to be understood that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structures and functions 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 invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
