Detailed Description

To further explain the features and technical contents of the present invention, please refer to the following detailed description and accompanying drawings of the present invention, which are provided for reference and illustration purposes only and are not intended to limit the present invention.

Please refer to fig. 1 and fig. 2, which are an exploded view and an assembled view of the present invention. The utility model provides a heat dissipation device, which comprises a heat dissipation unit 1, a drainage structure 2 and a fan 3; wherein:

the heat dissipation unit 1 includes a base 10 and a fin set 11 disposed on the base 10, wherein the fin set 11 is formed by arranging a plurality of fins at intervals, so that external air can circulate in the fin set 11. Referring to fig. 3 and 4, a heat conducting plate 100 may be embedded in the bottom surface of the base 10, the exposed surface of the heat conducting plate 100 is used to contact with an electronic heating component (not shown) such as a CPU, and a plurality of protruding contact portions 100a may be disposed on the exposed surface of the heat conducting plate 100, and each contact portion 100a may be arranged in a matrix and fully distributed on the exposed surface of the heat conducting plate 100, thereby increasing a filling space for a heat conducting medium (not shown) such as a heat conducting paste and preventing the generation of a contact gap.

The flow guiding structure 2 includes a fan housing 20 and a connecting frame 21 disposed at one end of the fan housing 20, the fan housing 20 may be formed by punching or bending a plate made of a metal material to form a covering space 200 therein, and the covering space 200 has an opening 200a at each of two ends of the fan housing 20, so that the fan housing 20 can cover the fin group 11 through the covering space 200, i.e., the fin group 11 is located in the covering space 200, and the fan housing 20 can be locked with the base 10 through a screw or other component to be combined.

As mentioned above, the connecting frame 21 is selectively disposed outside any one of the openings 200a of the fan housing 20, and is formed by a top edge 210 and two side edges 211 respectively located at two sides of the top edge 210 being retracted inward, and then two side edges 211 respectively extending inward a short edge 212 and being opposite to each other, and a lug 213 is respectively disposed at an inner corner of four corners of the connecting frame 21 for locking and fixing the fan 3. In addition, for the convenience of assembling and aligning the fan 3, an upper limiting plate 210a may be protruded from an inner edge of the top edge 210, and a side limiting plate 211a may be protruded from an inner edge of the two sides 211, respectively, so that the fan 3 may be aligned according to a space enclosed by the upper limiting plate 210a and the two side limiting plates 211a, and then locked and combined.

In addition, the periphery of the base 10 may be provided with a plurality of fixing elements 12, and the fin set 11 may also be provided with

vacant spaces

110, 111 in cooperation with the arrangement of each fixing element 12, and the top surface of the fan housing 20 is also provided with an opening 201 and a vacant edge 202 in cooperation with each

vacant space

110, 111. In the embodiment of the present invention, the open space 110 located at an opening 200a of the fan housing 20 corresponds to the opening 201; the gap space 111 at the other opening 200a of the hood 20 corresponds to the gap 202. The design may be determined according to the requirement, and if the fin assembly 11 is not exposed outside the fan housing 20, the opening 201 may be disposed; if the fin assembly 11 is partially exposed out of the fan housing 20, the above-mentioned default 202 may be adopted.

Therefore, the heat dissipation device of the present invention can be obtained by the above structure.

Accordingly, as shown in fig. 5, the present invention makes the fan 3 better and effectively concentrate the airflow or cold air provided by the fan 3 into the fan housing 20 through the design of the connecting frame 21 of the flow guiding structure 2, so as to provide the fin group 11 located in the fan housing 20, thereby obtaining good cooling and heat dissipation effects; in this embodiment, the fan 3 is implemented at an opening 200a of the fan housing 20. As shown in fig. 6, the fan 3 is disposed at another opening 200a of the fan housing 20; by changing the arrangement position and direction of the fan housing 20 and the heat dissipation unit 1, the fan 3 can be adjusted in position according to the situation, thereby reducing the usage limitation and increasing the flexibility in usage.

The above is only the preferred practical embodiment of the present invention, and not therefore the scope of the present invention is limited, so that all the equivalent structural changes made by the descriptions and drawings of the present invention are equally contained in the scope of the present invention, and it is well known.
