Description
- 1. Field of the Invention
- The present invention relates to a heat dissipation device for removing heat from a heat-generating device, and more particularly to a heat dissipation device having heat pipes and improved fin structure incorporated therein.
- 2. Description of Related Art
- As computer technology continues to advance, electronic components such as central processing units (CPUs) of computers are being made to provide faster operational speeds and greater functional capabilities. When a CPU operates at high speed in a computer enclosure, its temperature usually increases enormously. It is therefore desirable to dissipate the generated heat of the CPU quickly before damage is caused.
- A conventional heat dissipation device for this purpose generally includes a plurality of parallel fins and a heat pipe inserted in the fins. The heat pipe is in thermal engagement with a CPU; thus, heat originating from the CPU is spread through the fins via the heat pipe, and is then dissipated to ambient air.
- The fins and the heat pipe are generally made of heat conductive material. In practice, the fins are usually made of aluminum while the heat pipe is usually made of copper when the weight and the cost of the heat dissipation device are taken into consideration. The fins are generally bonded to an outer surface of the heat pipe via soldering. However, aluminum is difficult to solder, and a coat of nickel or cooper is often applied to the fins via plating to ease soldering of the fins. This complicates the manufacturing process of the fins; as a result, production cycle time and the cost of the heat dissipation device are unduly increased.
- What is needed, therefore, is a heat dissipation device, which can overcome the above-described disadvantages.
- A heat dissipation device comprises a fin assembly comprising a plurality of fins and a heat conductive member. Each individual fin comprises a main body with one through hole and a sleeve installed in the through hole of the main body. The sleeve has a hole defined therethrough. The heat conductive member has higher heat conductivity than the fin, and is installed into the through hole of the main body via insertion through the hole in the sleeve. The main body and the sleeve of the each individual fin are made of different materials so that the sleeve serves as a transition component for facilitating mounting of each individual fin on the heat conductive member. The sleeve is made of a metal having a heat conductivity higher than that of a metal for forming the main body. Furthermore, the metal for forming the sleeve can be easily soldered to the heat conductive member, which is a heat pipe.
- Other advantages and novel features will become more apparent from the following detailed description of preferred embodiments when taken in conjunction with the accompanying drawings, in which:
- Many aspects of the present embodiments can be better understood with reference to the following drawings.

FIG. 3 is an exploded view of the fin inFIG. 2 ; -
FIG. 4 is a cross-sectional view of the fin inFIG. 2 taken from a line III-III inFIG. 2 ; and -
FIG. 5 is similar toFIG. 4 , showing that a sleeve inFIG. 4 further comprising a flange. - Referring to
FIG. 1 , a heat dissipation device in accordance with a preferred embodiment of the present invention is illustrated. The heat dissipation device generally comprises afin assembly 10 and two heatconductive members 20, such as two heat pipes inserted into thefin assembly 10. The heatconductive members 20 have higher heat conductivity than thefin assembly 10, and are in thermal engagement with a heat-generating component, such as a CPU (not shown) so as to transfer heat originating from the CPU to thefin assembly 10 to be dissipated to ambient air. - The
fin assembly 10 comprises a plurality ofindividual fins 100 arranged one by one, one of which is shown inFIGS. 2-4 . Thefin 100 comprises amain body 120 and twosleeves 140 pre-assembled in themain body 120. - The
main body 120 generally has a rectangular shape, and comprises aflange 122 perpendicularly extending from a bottom thereof. Themain body 120 further comprises two spaced throughholes 124 for receiving the heatconductive members 20. Anannular wall 126 protrudes from an edge of each throughhole 124, and is located at a front side, or a first side of themain body 120. The presence of theannular walls 126 will increase the contacting area between themain body 120 and the heatconductive members 20, thus more effectively transferring heat from the heatconductive members 20 to eachindividual fin 100. Additionally, the increase of the contacting area between the heatconductive members 20 and thefins 100 will produce greater structural stability. Eachmain body 120 is made of heat conductive material, such as metal, more particularly aluminum when the cost and the weight of the heat dissipation device are taken into consideration. Since the aluminum solders poorly, the twosleeves 140 made of material, which can be soldered easily and has higher heat conductivity than aluminum, such as copper or silver, are used to improve the bonding strength and heat conduction between thefins 100 and the heatconductive members 20. In other words, thesleeves 140 overlap an inner surface of the throughholes 124 of themain body 120 to separate the heatconductive members 20 from themain body 120; as a result, the heatconductive members 20 are in indirect thermal engagement with thefin 100. The detailed structure of thesleeves 140 will be described in the following text. - Each
sleeve 140 is generally cylindrical in shape, although it should be understood that the cross-section of thesleeve 140 may be square, rectangular, elliptical or other cross-section as may be selected according to the shapes of the heatconductive members 20 and the throughholes 124 of thefins 100. Thesleeve 140 generally comprises ahollow body 142 and anannular lip 144 formed at a rear end of thehollow body 142. Ahole 146 is defined through theentire sleeve 140 and coaxial with an axis of thehollow body 142. Thehole 146 of thesleeve 140 has an inner diameter larger than an outer diameter of the heatconductive member 20, while thehollow body 142 has an outer diameter slightly larger than an inner diameter of thethrough hole 124 of themain body 120. Thelip 144 of thesleeve 140 has a diameter larger than the inner diameter of the throughhole 124 of themain body 120 so that thelip 144 serves as a stop or shoulder for limiting the insertion of thesleeve 140 into thethrough hole 124 of themain body 120. - When the two
sleeves 140 are assembled with themain body 120, thehollow bodies 142 of thesleeves 140 are press-fitted into the throughholes 124 of themain body 120 with theannular walls 126 tightly surrounding the outer surfaces of thehollow bodies 142 of thesleeves 140. At the same time, thelips 144 of thesleeves 140 are positioned at a rear side, or a second side of themain body 120, overlapping an area in close proximity of the throughholes 124 of themain body 120. Thelips 144 may be connected to themain body 120 via riveting, punching and other methods. Therefore, thesleeves 140 are firmly installed in themain body 120. - In this embodiment, the
lips 144 not only increase the contacting area between thefin 100 and thesleeves 140, but also ensure that thesleeves 140 are firmly installed in themain body 120. For another embodiment, thelips 144 may be only used to increase the contact area between themain body 120 and thesleeves 140. - As described above, the
sleeves 140 may be installed in themain body 120 via interference fit, riveting, punching, and so on. Moreover, thesleeves 140 can be firmly installed in the throughholes 124 of themain body 120 as a result of a process of synchronous fabrication of the throughholes 124 of themain body 120 and thesleeves 140 via punching or piercing. This process comprises following steps: - step (1) providing a first planar plate made of aluminum, which is used for manufacturing the
main body 120; - step (2) providing two second planar plates made of copper or silver, which are used for manufacturing the
sleeves 140; each second planar plate has a size smaller than that of the first planar plate; - step (3) placing the second planar plates on a predetermined place of the first planar plate, where the through
holes 124 of themain body 120 are to be formed; - step (4) piercing the second planar plates and the first planar plate along a direction perpendicular to the first planar plate to create the through
holes 124 with theannular walls 126 and thehollow bodies 142 of thesleeves 140, which are in an interference fit with theannular walls 126, meanwhile, parts of the second planar plates that are unchanged form thelips 144. - Therefore, the
sleeves 140 are firmly installed in the throughholes 124 of themain body 120 at the same time that the throughholes 124 with theannular walls 126 and thesleeve 140 are synchronously fabricated. - For further ensuring that
sleeves 140 are firmly installed in the throughholes 124 of themain body 120, a front end of eachsleeve 140 may be shaped so as to create aflange 148 as shown inFIG. 5 . Theflange 148 is bent outwardly from the front end of thehollow body 142 to abut against a front end of theannular wall 126, thus preventing thesleeve 140 from escaping from the throughhole 124 of themain body 120. As a result, theannular wall 126 of themain body 120 is held between theflange 148 and thelip 144 of thesleeve 140. - After the
sleeves 140 are assembled into the throughholes 124 of themain body 120, thefins 100 are arranged one by one to form thefin assembly 10 with theholes 146 of thesleeves 140 fixed in onefin 100 aligning with the associatedholes 146 of thesleeves 140 fixed in theadjacent fins 100. As a result, two passages are defined transversely extending through thefin assembly 10. The heatconductive members 20 are inserted into the associated passages of thefin assembly 10. Finally, the heatconductive members 20 are soldered into the passages by soldering the heatconductive members 20 and thehollow bodies 142 of thesleeves 140 together. - Since the
sleeves 140 are positioned between the heatconductive members 20 and the throughholes 124 of themain body 120 and serve as transition components, thefins 100 can be firmly bonded to the outer surface of the heatconductive members 20 without being nickel-plated first, and themain body 120 and the heatconductive members 20 may be made of different material. Thus, production cycle time and cost of the heat dissipation device are reduced. - It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
