Description
- 1. Technical Field
- The disclosure relates to a heat dissipation device and, more particularly, to a heat dissipation device having a fan holder for securing a fan onto a heat sink of the heat dissipation device, wherein the fan holder can be easily assembled to and disassembled from the heat sink to mount/dismount the fan to/from the heat sink.
- 2. Description of Related Art
- It is well known that during operation computer electronic devices such as central processing units (CPUs) can generate large amounts of heat. The heat must be quickly removed from the electronic device to prevent it from becoming unstable or being damaged. Typically, a heat sink is attached to an outer surface of the electronic device to absorb heat from the electronic device, and the heat absorbed by the heat sink is then dissipated to ambient air.
- Generally, in order to improve heat dissipation efficiency of a heat sink, a fan is desired to direct airflow onto the heat sink. It is generally to fix the fan onto the heat sink with screws. Furthermore, it is necessary to disassemble the fan from the heat sink when dust particles accumulate in the fan and the heat sink, whereby the fan and the heat sink can be cleaned. Otherwise, heat dissipation efficiency of the heat sink will be decreased and a lifespan of the fan will be shortened. After cleaning of the fan and heat sink, it is required to assemble the fan to the heat sink again. Both the disassembling and assembling require rotating the screws by using a screwdriver. Such an unscrewing and screwing operation is laborious and time consuming. In addition, it is possible that the screws or screwdriver may drop to cause damages to computer components in the process of assembling and disassembling.
- What is needed, therefore, is a heat dissipation device which has a fan holder for mounting a fan onto a heat sink wherein the fan can be easily assembled to and disassembled from the fan holder without any tool.
- Many aspects of the disclosure 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 disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

In this embodiment, theheat sink 30 is made of aluminum and formed by extrusion. Theheat sink 30 comprises abase 31, a plurality offirst fins 34 andsecond fins 35 integrally extending upwardly from a top face of thebase 31. Thefirst fins 34 are parallel to each other to define a plurality of lengthwise channels therebetween. Thesecond fins 35 are located at two opposite sides of thefirst fins 34. Thesecond fins 35 define a plurality oftransversal channels 351. A pair offixture blocks 355 extend from top edges of middles of two outmostsecond fins 35, respectively. Thefixture blocks 355 are used to engage with thefan holder 40 for securing thefan 80 on theheat sink 30. - The
fan holder 40 is made of metal wires, and comprises afan guard 50, two locatingmembers 55 mounted at two opposite sides of thefan guard 50, afirst wire clip 70 and asecond wire clip 90 pivotably attached to other two opposite sides of thefan guard 50. The locatingmembers 55 engage two opposite sides of thefan 80 to connect thefan holder 40 and thefan 80 together. The first andsecond clips fixture blocks 355 of theheat sink 30 to securely mount thefan 80 on theheat sink 30. The locatingmembers 55 and the first andsecond clips fan 80 from movement in the lengthwise and transversal directions. - The
fan guard 50 has a grill-like construction. Thefan guard 50 has a plurality of substantiallycircular ribs 51 concentrically spaced from each other, and two V-shaped supporters 52 interconnecting thecircular ribs 51 as a whole. A second one of theribs 51 counted inwardly from an outside of thefan guard 50 has two portions thereof, located corresponding to theclips second protrusions first clip 70 and thesecond clip 90 respectively. Each of theprotrusions first protrusion 59 is narrower and taller than thesecond protrusion 58. Each of the locatingmembers 55 is integrally made from a unitary metal wire, comprising amounting portion 56 soldered on theribs 51 of thefan guard 50 and a locatingportion 57 downwardly extending from themounting portion 56. - The
first clip 70 comprises an actuatingmember 71 pivotably coupled to theprotrusion 59 of thefan guard 50 and abuckling member 75 pivotably coupled to the actuatingmember 71. The actuatingmember 71 is integrally made from a unitary metal wire, and has a substantially U-shaped configuration. Twofree ends 72 of two parallel arms (not labeled) of the actuatingmember 71 are bent to be circular to pivotably connect to thefirst protrusion 59 of thefan guard 50. Middle portions of the two parallel arms of the actuatingmember 71 each are bent around 360 degrees to form a circularpivotal portion 73 which defines a pivoting hole therein. A transversal arm (not labeled) of the actuatingmember 71 between the parallel arms thereof functions as a handle for a user to grip the actuatingmember 71 to rotate the actuatingmember 71 about theprotrusion 59. Thebuckling member 75 comprises aclasp 77 and two connectingportions 78 perpendicularly extending from two free ends of theclasp 77. Theclasp 77 has a U-shaped configuration and abar 79 in middle portion for strengthening theclasp 77. The connectingportions 78 inwardly extend two pivots at two free ends thereof. The pivots of theclasp 77 are pivotably inserted into the pivoting holes of thepivotal portion 73 of the actuatingmember 71. - Similar to the
buckling member 75 of thefirst clip 70, thesecond clip 90 comprises aclasp 91 and two connectingportions 92 perpendicularly extending from top ends of theclasp 91. Theclasp 91 has a U-shaped configuration for engaging thefixture block 355 of theheat sink 30. The connectingportions 92 each are bent to be circular to pivotably connect to thesecond protrusion 58 of thefan guard 50. - Referring to
FIG. 2 , thefan 80 is placed on theheat sink 30 and theclasp 91 of thesecond clip 90 clasps onefixture block 355 of theheat sink 30. At this time, thefan holder 40 is located at an unlocked position. Referring toFIGS. 3-4 , in operation, thefan holder 40 is rotated relative to thesecond clip 90, with thefan guard 50 abutting against top of thefan 80, and the locatingmembers 55 engaging the two opposite sides of thefan 80. The actuatingmember 71 is then pushed outwardly to rotate clockwise around thefree ends 72 of the actuatingmember 71 and theprotrusion 59 for about 180 degrees, to thus lower thebuckling member 75 to reach a position in which a bottom horizontal arm (not labeled) of thebuckling member 75 is located below theother fixture block 355. Then, the actuatingmember 71 is pushed reversely and inwardly to rotate anticlockwise around thefree ends 72 and theprotrusion 59 for about 180 degrees until the actuatingmember 71 returns to the position ofFIG. 1 in which the actuatingmember 71 abuts thefan guard 50 and the bottom horizontal arm of thebuckling member 75 securely engages with a bottom of theother fixture block 355. Thebuckling member 75 is driven by the actuatingmember 71 to produce a deformation to make theclasp 77 firmly engage with theother fixture block 355 ofheat sink 30. At this moment, thefirst clip 70 is located in the locked position and thefan guard 50 firmly presses thefan 80 on theheat sink 30. Therefore, thefan 80 is pushed downwardly and firmly mounted on theheat sink 30 by thefan holder 40. - In this embodiment, the actuating
member 71 which pivotably connects thefirst protrusion 59 of thefan guard 50, and the bucklingmember 75 which clasps the other fixture block 355 of theheat sink 30 together form a connection mechanism. When thefirst clip 70 is at the locked position, thepivotal portions 73 of the actuatingmember 71 are rotated beyond a dead point of the connection mechanism; thus, the actuatingmember 71 is self-locked at the locked position and not easily to be loosed. Furthermore, when thefirst clip 70 is at the locked position, thefirst protrusion 59 of thefan guard 50 is higher than thepivotal portions 73 of the actuatingmember 71, and thefirst clip 70 is thereby firmly held at the locked position. - To unlock the
fan holder 40, the actuatingmember 71 of thefirst clip 70 is turned from the locked position to the unlocked position along the clockwise direction, at which clasp 77 is disengaged from theother fixture block 355. Then, thefan 80 can be easily removed from theheat sink 30. - As the pivotal connection between the actuating
member 71 and the bucklingmember 75 is located between the handle of the actuatingmember 71 and the pivotal connection between actuatingmember 71 and theprotrusion 59, when a user or operator exerts a relative smaller force on the actuatingmember 71, the bucklingmember 75 can be driven to move so that thefirst clip 70 firmly secures thefan 80 onto theheat sink 30. Therefore, thefan holder 40 is user-friendly. Furthermore, when the actuatingmember 71 of thefirst clip 70 is at the locked position, the actuatingmember 71 is located on thefan guard 50; accordingly, the space needed for accommodating the actuatingmember 71 of thefirst clip 70 is reduced. - Alternatively, the
second clip 90 can be replaced by thefirst clip 70; in other words, thefan holder 40 can have twofirst clips 70 at the two opposite sides of thefan guard 50. - It is to be understood, however, that even though numerous characteristics and advantages of the present 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
