Therefore, the cooling efficiency provided by the heat sink 20 of the existing central processing unit 10 is obviously limited. The heat dissipation efficiency of 20 is obviously not enough to meet the demand.

Utility model content

In order to overcome the shortcomings of the existing central processor radiators, which have limited heat dissipation area in contact with the air, low heat dissipation efficiency, and cannot meet the increasingly fast information processing speed of the central processor, the utility model provides a radiator for the central processor, which It can greatly increase the heat dissipation area and have more air circulation paths, thereby improving the heat dissipation efficiency of the central processing unit.

The technical scheme that the utility model solves its technical problem adopts is:

A heat sink for a central processing unit, comprising a flat base attached to the upper surface of the central processing unit, and several cooling fins standing upright on the flat base, characterized in that each cooling fin has several a plurality of first protruding portions arranged at approximately trapezoidal intervals, the first protruding portions protrude on one side of the center line of the side surface of the heat sink, and several trapezoidal oppositely disposed on two adjacent first protruding portions The second protruding part between, make the second protruding part be located on the other side of the centerline of the side of the heat sink, the first protruding part and the second protruding part are connected to each other to form a generally wavy plate, thereby improving Heat dissipation area; the side wall where the first protruding part is connected with the second protruding part has several third protruding parts protruding at intervals, so that the third protruding part is located at the first protruding part or the second protruding part On one side of the central line of the protruding part, several fourth protruding parts are provided in opposite directions between two adjacent third protruding parts, so that the fourth protruding part is located at the center of the first protruding part or the second protruding part On the other side of the line, a hole is formed between the third protruding part and the two sides of the fourth protruding part and the first protruding part and the second protruding part, thereby providing more directional air circulation paths , thereby improving the heat dissipation efficiency of the radiator.

The beneficial effect of the utility model is that it can greatly increase the heat dissipation area, have more air circulation paths, and further improve the heat dissipation efficiency of the central processing unit.

Detailed ways

As shown in Figure 3, the heat sink 40 of the central processing unit 30 of the present invention includes a flat base 41 that can be attached and contacted on the upper surface of the central processing unit 30, and several cooling fins 42 standing upright on the flat base 41 , characterized by:

Please also refer to FIG. 4 to FIG. 8 , each heat sink 42 has a plurality of first protruding portions 421 arranged at approximately trapezoidal intervals, and the first protruding portions 421 are protruded on the sides of the heat sink 42 On one side of the center line L1 (as shown in FIG. 5 ), there are several second protrusions 422 arranged oppositely between two adjacent first protrusions 421 in a trapezoidal shape, so that the second protrusions 422 are located at On the other side of the side center line L1, the first protruding portion 421 and the second protruding portion 422 are connected to each other to form a generally wavy plate, thereby increasing the heat dissipation area; at the same time, between the first protruding portion 421 and the There are several third protrusions 423 protruding at intervals on the side walls connected to the second protrusions 422, so that the third protrusions 423 are located on the center line of the first protrusions 421 or the second protrusions 422 One side of L2 (as shown in FIG. 6 ), and several fourth protruding parts 424 that are oppositely protruded between two adjacent third protruding parts 423, and make the fourth protruding part 424 be located on the first protruding part 424. The other side of the central line L2 of the protruding part 421 or the second protruding part 422, and make the third protruding part 423, the two sides of the fourth protruding part 424 and the first protruding part 421, the second protruding part respectively. A hole 425 (as shown in FIG. 7 ) is formed between the 422 , thereby providing more directional air circulation paths, thereby improving the heat dissipation efficiency of the radiator 40 .

Please refer to shown in Fig. 8 again, when the utility model is in use, it can also be the same as the current general radiator, and a heat dissipation fan 60 can be assembled on the top of the radiator 40 by means of a fixing seat 50, which can further improve the heat dissipation efficiency; The space between the heat sink 42 and the heat sink 42 in the central position of the heat sink 40 is pierced with a fixed piece 70, and the two ends of the fixed piece 70 are locked on the substrate, so that the flat base 41 of the heat sink 40 can be closely attached contact with the upper surface of the CPU 30 .
