Description

IP Australia N 1 9 OCT 2006 00 o\ tt TITLE: HEATSINK DEVICE HAVING FIBER-LIKE FINS SBACKGROUND OF THE INVENTION Technical Field of the Invention SThe present invention generally relates to heatsink devices for IC chips, and more particularly to a heatsink device having a large number of fiber-like fins.

Description of the Prior Art IC chips are the most important components in computers and various electronic appliances, and they are producing more heat than before as they are driven by faster clocks and more functionality is integrated. This heat, without proper dissipation, would reduce the operation life of the chip if the chip is not damaged in the first place. The neighboring electronic components are often affected by the heat as well. Most of the IC chips are therefore used along with heatsink devices usually manufactured by aluminum extrusion. The conventional aluminum-made heatsink device is bulky and provides limited heat dissipation capability so that an auxiliary fan is usually required to drive cool air through the heatsink device, therefore taking up even more space. For today's electronic appliances and computers which are driven by market demands for even smaller form factors and more appealing outlook, the inflexibility of conventional heatsink devices has become a major 0 02 It and serious obstacle to overcome.

IND

0O 0 It SUMMARY OF THE INVENTION o The primary purpose of the present invention is to provide a heatsink Sdevice, which mainly contains a large number of fins made of highly thermal Sconducting material into fiber-like linear segments. The fiber-like fins have one of their ends inserted into tubular holders which are fused or welded together to form a planar base, or into the holes on the top surface of a planar base. The fiber-like fins therefore extend upward with appropriate spacing among them.

The present invention offers a number of advantages. First, the fiber-like fins significantly increase the heatsink device's contact area with air for superior heat dissipation efficiency. Secondly, the fiber-like fins can be easily manipulated and woven into webs to fit limited or irregular interior space of various electronic appliances without sacrificing the heat dissipation efficiency The foregoing object and summnary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference

06 0 It DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 00 The following descriptions are of exemplary embodiments only, and are \0 not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention.

Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

As illustrated in FIGS. 1 to 3, the heatsink device according to an embodiment of the present invention has a very large number of fins 1, each made by a highly thermal conducting material into a very thin fiber-like linear segment of 0.05-0.2 mm in diameter. Every 3 to 5 fiber-like fins are supported together as a bundle by having one of their ends inserted into a tubular holder 2. All tubular holders 2 are welded or fused side by side to one another to form a planar base fi-om which the fiber-like fins 1 extend vertically upward with appropriate spacing among the bundles.

The heatsink device of FIG 3 can be directly installed on top of an IC chip and the heat fiom the IC chip is directly conducted to the fiber-like fins 1.

As the fiber-like fins 1 have dramatically larger contact area with air than the conventional heatsink device, the heat is quickly dissipated. For IC chip

I)

0 7 n producing significant amount of heat, the heatsink device can be configured 00 O inside a frame 3 where a fan 5 is provided on a side to enhance the cooling i, effect of the heatsink device. As shown in FIG 4, another embodiment of the present invention has a planar base 2A with a large number of holes (not numbered) into which the fiber-like fins are inserted. As such, the fiber-like fins 1 extend vertically upward with appropriate spacing among them.

When the heatsink device of the present invention has to be housed inside appliances having very limited or irregular interior space, as shown in FIG the fiber-like fins 1 can be bended and woven into webs to fit the special space limitation while maintaining superior heat dissipation efficiency.

It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the ailrt without departing in any way from the spirit of the present invention.
