Accordingly, the first and the second sets of fins are corresponding to each other so that the heat sink module obtains larger heat dissipation area and the function of two-side dissipation to achieve better heat dissipation efficiency.

FIELD OF THE INVENTION

The present invention relates to a heat sink module; more particularly, relates to forming two symmetrical sets of fins in the module to get larger heat dissipation area and to dissipate heat at both sides so that a better heat dissipation efficiency is achieved.

DESCRIPTION OF THE RELATED ART

The prior art of “Heat sink apparatus” as disclosed in U.S. Pat. No. 6,525,939 comprising: a fan comprising at least one attachment hole; a heat sink module mounted on the CPU, comprising a metal heat conduction column, a plurality of arc-shaped cooling fins radiating from the edge of the metal heat conduction column and a plurality of mounting holes positioned at the ends of the arc-shaped cooling fins, corresponding to the attachment holes; and a latch comprising a latch arm, a plurality of openings and at least one latch hole.

Therein, the latch arm is secured to the socket of the CPU; each of the openings correspond to the mounting holes and the attachment holes; the fan and the heat sink module are mounted onto the CPU with the latch; and the metal heat conduction column is a cylinder in direct contact with the CPU and is hollowed out as being filled with a metal having a heat conductibility that is better than the heat conductibility of the metal of the column.

Although the prior art mentioned above is able to dissipate heat by a heat sink module, the heat sink module is formed as a unity with limited dissipation area so that the heat dissipation efficiency is limited. So, the prior art can not fulfill the requirements from the user on actual use.

SUMMARY OF THE INVENTION

Therefore, the main purpose of the present invention is to form a first set of fins and a second set of fins to be symmetrical in the module to get larger heat dissipation area so that a better heat dissipation efficiency is achieved.

Another purpose of the present invention is to form the first set of fins and the second set of fins to be symmetrical in the module to dissipate heat at two sides so that a better heat dissipation efficiency is achieved.

To achieve the above purposes, the present invention is a symmetrical heat sink module with a heat pipe for spreading of heat, comprising a first and a second sets of fins symmetrically formed; a curved (U-type) heat pipe between the two sets of fins; and a base at the bottom of the curved heat pipe. The two sets of fins comprise a first heat dissipation area at the bottom of each set of fins; a second heat dissipation area on a surface of each set of fins near the first heat dissipation area; two vicinal concave parts on the opposite surface of each set of fins where the two sets of fins are combined by the two surfaces having the concave parts. The curved heat pipe is deposited in the concave parts of the two sets of fins; and the bottom of the curved heat pipe is convex out of the bottom of the two sets of fins. The base is deposited at the convex bottom of the curved heat pipe, and comprises a connection part corresponding to the bottom of the curved heat pipe. So, by the first and second sets of fins formed symmetrically, the heat sink module gains larger heat dissipation area and the ability of heat dissipation at two sides to achieve better heat dissipation.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The following descriptions of the preferred embodiments are provided to understand the features and the structures of the present invention.

Please refer toFIG. 1throughFIG. 3, which are a perspective view, an exploded view showing the structure and a side view, according to an embodiment of the present invention. As shown in the figures, the present invention is a symmetrical heat sink module with a heat pipe for spreading of heat, comprising a first set1of fins, a second set2of fins. a heat pipe3and a base4. The first and the second sets1,2of fins are made of alumni, copper, alumni alloy or copper alloy which has better heat dissipation capability.

The first set1of fins comprises a first dissipation area11at the bottom, which is extended up from the bottom toward an end. A second dissipation area12is on a surface of the first set1of fins near the first dissipation area11extended outwardly from the surface of the first set1of fins. The first and the second dissipation areas11,12comprise a plurality of fins111,121. And, the first set1of fins comprises two vicinal concave parts13on the opposite surface, a combination part14at an end, and an indentation15at the edge of the bottom.

The second set2of fins is symmetrical to the first set1of fins and comprises a first dissipation area21at the bottom which is extended up from the bottom toward an end. A second dissipation area22is on a surface of the second set2of fins near the first dissipation area21extended outwardly from the surface of the second set2of fins. The first21and the second22dissipation areas comprise a plurality of fins211,221. And, the second set2of fins comprises: two vicinal concave parts23on the opposite surface to the surface having first dissipation area21where the first1and the second2sets of fins are combined by the surfaces having concave parts13,23; a combination part24at an end, corresponding to the combination part14of the first set1of fins to combine the two sets of fins by a rivet member26; and an indentation25corresponding to the indentation15of the first set1of fins at the edge of the bottom of the second set2of fins.

The heat pipe3is deposited in the concave parts13,23of the first and the second sets1,2of fins; and an end of the heat pipe3is convex out of the corresponding concave parts at the bottom of the first1and the second2sets of fins. The heat pipe3can be a U-type heat pipe capable of capillarity with liquid inside; or can be a loop heat pipe.

The base4is deposited at the convex part of the end of the heat pipe3and is made of alumni, copper, alumni alloy or copper alloy which has better heat dissipation capability. The base4includes a connection part41which is corresponding to the convex part at the end of the heat pipe3. By the above structure, a novel symmetrical heat sink module with a heat pipe for spreading of heat is obtained.

Please refer toFIG. 4andFIG. 5, which are a view showing the status of use and a sectional view showing the status of use, according to an embodiment of the present invention. As shown in the figures, on using, the base4of the embodiment according to the present invention can be put on the heating component51which can be the CPU on the main board5. A fan6can be set at a side of the present invention to blow wind at a side. Once the heating component51on the main board5is activated, the heating component51keeps generating heat. At the time, the base4starts absorbing the heat so that a part of the heat is transmitted to the first dissipation areas11,21to be dissipated through the first and the second sets1,2of fins. And some other part of the heat generated is transmitted to the heat pipe3through the base4. And then, the heat is transmitted to the second dissipation areas12,22at a side of the first and the second sets1,2of fins so that the heat can be dissipated through the second dissipation areas12,22coordinated with a fan6. When the heat is carried out by the wind generated by the fan at a side, the wind with heat will be guided to an end of a computer case (not shown in the figures). In this way, the wind with heat can be exhausted by the fan on the computer case so that thermal cycling will not happen in the computer case by the wind with heat. By doing so, the first and the second sets of fins are corresponding to each other so that the heat sink module obtains larger heat dissipation area and the function of two-side dissipation to achieve better heat dissipation efficiency.
