1. Field of the Invention
The present invention relates to cooling fin structures and heat-dissipating modules thereof, and more particularly, to a cooling fin structure capable of guiding and concentrating a heat-dissipating fluid and a heat-dissipating module thereof.
2. Description of the Prior Art
With information-related electronic products (for example, computers) becoming more popular and versatile and the development of demand-led information-related electronic industry/technology becoming faster, there is a trend toward increasingly high capacity access and increasingly fast computation of electronic information. As a result, parts and components of information-related electronic products always generate a tremendous amount of heat during high-speed operation.
Take a host computer as example, the central processing unit (CPU) installed therein accounts for most of the heat generated by the host computer. Accumulation of heat inside the host computer usually accompanies deteriorating CPU performance, causes the host computer to hang as soon as the accumulated heat goes beyond a limit, and even damage the host computer in a serious scenario. More badly, to address the issue of electromagnetic radiation, the host computer is usually enclosed by a casing in an airtight manner. Hence, an important issue facing the information-related electronic industry involves rapid removal of heat from the CPU and heat-generating components.
To facilitate heat dissipation, a conventional CPU is installed with a heat sink thereon, and the heat sink has one side equipped with some fins and the other side (not equipped with fins) in immediate contact with the CPU, so as to transfer heat to the end of each of the fins and then dissipate the heat rapidly by radiation or an additional fan capable of blowing air.

SUMMARY OF THE INVENTIONIn light of the aforesaid drawbacks of the prior art, it is a primary objective of the present invention to provide a cooling fin structure favorable for an increased heat dissipation area.
Another objective of the present invention is to provide a cooling fin structure and a heat-dissipating module thereof so as to guide a running fluid from two peripheral sides of the cooling fin structure to the center of the cooling fin structure and stop the running fluid from spreading to the two peripheral sides of the cooling fin structure.
Yet another objective of the present invention is to provide a cooling fin structure and a heat-dissipating module thereof capable of guiding a heat-dissipating fluid.
To achieve the aforesaid objectives, the present invention provides a cooling fin structure and a heat-dissipating module thereof. The cooling fin structure comprises a plate, a first guiding portion, and a second guiding portion. The first guiding portion and the second guiding portion extend from and form integrally with the plate bilaterally with a first included angle between the first guiding portion and the plate and a second included angle between the second guiding portion and the plate. The cooling fins are stacked up and coupled to a heat pipe, a base, and a fan to form a heat-dissipating module. The first guiding portion and the second guiding portion of the cooling fin structure guide a fluid generated by the fan to the plate and concentrate the fluid therein, so as to allow the fluid to flow smoothly and greatly enhance heat dissipation. Accordingly, the present invention has the following advantages:
- 1. air stream guidance and enhanced heat dissipation
- 2. large heat dissipation area and heat-dissipating space
- 3. smooth flow of a fluid in heat-dissipating space
- 4. concentrating a heat-dissipating fluid
- 5. efficient heat exchange
