Abstract
Description
- 1. Technical Field
- The present disclosure relates to heat dissipation devices, and particularly to a heat dissipation device for cooling an electronic component of a circuit board.
- 2. Description of Related Art
- Heat dissipation devices are popularly used in electronic devices, such as computers or servers. Usually, a bridge chip in a computer or a server uses a heat dissipation device for increased heat conduction. If the performance of the heat dissipation device is not good, the bridge chip may be overheated and damaged. Therefore, good heat dissipation is critical for the electronic device.
- However, different bridge chips usually require different heat dissipation devices for increasing heat conduction. Locations, space, and heat dissipation requirements of the heat dissipation devices for different bridge chips are different. As a result, application of different heat dissipation devices for different bridge chips is costly and time-consuming.
-
FIG. 1 is an exploded, isometric view of a heat dissipation device in accordance with an embodiment. -
FIG. 2 is a partially assembled view ofFIG. 1 . -
FIG. 3 is an assembled view ofFIG. 1 . - Referring to
FIG. 1 , an exemplary embodiment of a heat dissipation device includes asquare plate 10 to be located on a top of an electronic element, such as a bridge chip of a circuit board. Four heat sinks 20 mounted on theplate 10 to absorb heat from the electronic element. Aclip 40 made of resilient material to fix theplate 10 on the circuit board, and fourfasteners 50, such as four screws, to mount theheat sinks 20 to theplate 10. - Each
heat sink 20 includes abase 21 and a plurality ofparallel fins 23 extending perpendicular from thebase 21. Afixing hole 212 is defined in a center of thebase 21. In one embodiment, thebases 21 of theheat sinks 20 are the same, while heights of the plurality offins 23 of eachheat sink 20 differ. Size of thebase 21 and height of the plurality offins 23 of eachheat sink 20 can be predetermined according to need. The number of theheat sinks 20 can be selected according to heat dissipation requirement of the electronic element. - A
cross-shaped protrusion 12 protrudes from a center of a top of theplate 10, to divide the top of theplate 10 into fourmounting areas 14, each for asingle heat sink 20. Sizes of themounting areas 14 are the same. Alocking hole 142 is defined in a center of eachmounting area 14, corresponding to thefixing hole 212 of acorresponding heat sink 20. Two pairs oftabs 144 extend perpendicular from theprotrusion 12. Two of each pair oftabs 144 are opposite to each other. Alatching portion 122 is formed between the tabs of each pair oftabs 144. In other embodiments, theplate 10 may be divided into three mounting areas by theprotrusion 12 of another shape. - The
clip 40 includes apositioning portion 42, two resistingportions 44 extending in opposite directions from opposite ends of thepositioning portion 42, and twoclasping portions 46 extending from distal ends of the resistingportions 44 respectively, away from thepositioning portion 42. The resistingportions 44 are fixed in thelatching portions 122, to resist theprotrusion 12 of theplate 10. - Referring to
FIGS. 2 and 3 , in use, when power for the electronic element is low, a few heat sinks 20, such as aheat sink 20 can be mounted on acorresponding mounting area 14 of theplate 10. Afastener 50 passes through thefixing hole 212 of theheat sink 20 to engage thelocking hole 142 of themounting area 14 to fix theheat sink 20 to theplate 10. When power for the electronic element is high, an increased number of theheat sinks 20, such as four, can be mounted on themounting areas 14 of theplate 10, respectively. Fourfasteners 50 pass through thecorresponding fixing holes 212 of theheat sinks 20 to engage thecorresponding locking holes 142 of themounting areas 14 to fix the fourheat sinks 20 to theplate 10. The claspingportions 46 of theclip 40 engage the circuit board to fix the heat dissipation device to the circuit board. - The
heat sinks 20 can be selectively mounted on theplate 10, and the number and shapes of theheat sinks 20 can be selected according to heat dissipation requirement for different chips. Theplate 10 is divided into a plurality of mounting areas by theprotrusion 12, for fixing a plurality of theheat sinks 20 on theplate 10. The heat dissipation device can satisfy different heat dissipation requirements for different chips of the circuit board. Therefore, the heat dissipation device is cost and time saving. - The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others skilled in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated. Alternately embodiments will become apparent to those skilled in the art to which the present disclosure pertains without departing from its spirit and scope. Accordingly, the scope of the present disclosure is defined by the appended claims rather than the foregoing description and the exemplary embodiments described therein.
