Compared with the prior art, the above-mentioned heat dissipation fins are integrally connected to each other via a buckle provided in the middle of the heat dissipation body, and the connection is stable, and the fastening mechanism is prevented from being disposed on the upper and lower sides of the heat sink in the prior art. The end affects the heat dissipation efficiency and the heat dissipation effect is good. In addition, the buckle of the invention is located in the middle of the body, and can be integrally formed by stamping, which saves the edge material and reduces the cost. [Embodiment] Please refer to FIG. 1 to FIG. 3' together. The heat sink includes a heat sink 1 , two heat pipes 70 , a heat dissipation fan 90 , and two fan fixing members 8 . The heat sink ίο includes a bottom plate 12 and a heat dissipation fin group 14. The heat dissipation fin group 14 is disposed above the bottom plate 12, and the plurality of heat dissipation fins 14 are buckled with each other to form a circular semicircular groove 146. Two semi-circular receiving slots 122 are defined in the two recesses 146 above the bottom plate 12, and the two recesses 146 and the two receiving slots 122 are combined to form two circular slots. Each heat pipe 7〇 includes a condensation section and an evaporation section, and the condensation section is disposed in the heat dissipation fin set 14 , the evaporation section is received in the two circular slots, and the fan fixing member 80 is fixed to the heat dissipation 8 201008473 fin On the chip set 14, the heat dissipation fan 90 is screwed onto the fan fixture 80. Each of the heat dissipation fins 140 constituting the heat dissipation fin group 14 includes a body '142 and a plurality of fastening pieces 144. A vertical slot 1422 is formed in the center of the body 142. The body 142 is divided into two symmetrical portions. The body 142 defines a through hole 1423 on each side of the slot 1422. The through holes 1423 of all the heat dissipation fins 140 are corresponding to each other. The condensation section of the heat supply pipe 70 is inserted. The slot 1422 does not extend up and down through the two ends of the body 142. The center of the bottom of the body 142 is provided with two arc-shaped holes. After the heat dissipating fins 140 are combined, all the arcuate holes jointly form the two grooves 146. The upper end of the main body 142 extends perpendicularly to the right and left sides to form a flange 1421. The flanges 1421 of all the heat dissipation fins 140 are combined to form a horizontal contact plane to set the fan fixing member 80°. 3 and 4, the plurality of buckles 144 extend from the middle of the body 142' toward the adjacent one of the front heat dissipation fins 140, and two of the left and right sides of the slot 1422 are respectively located at the left and right sides of the slot 1422. The vicinity of the through hole 1423 is described. Each of the cleats 144 is inclined from the top to the bottom of the slot 1422 and the two cleats 144 on the same side of the slot 1422 are parallel to each other. The body 142 defines an opening 1425 corresponding to each of the buckles 144. The opening 1425 is square. The two fastening pieces 144 on the same side of the slot 1422 are respectively located on the side opposite to the two openings 1425, that is, in the opening 1425. On the side of the hole 1423. The cleat 144 and the opening 1425 can be integrally formed at the same time by punching the heat dissipating fins 140. Each of the cleats 144 includes a joint portion 1441 connected to the main body 142, a fastening portion 1443 at a free end of the cleat 144, and an abutting portion 1442 between the joint portion 1441 and the engaging portion 1443. The length of 1441 is substantially equal to the length of the fastening portion 1443. The joint portion 9 201008473 portion 1441 is a rectangular sheet body extending perpendicularly outward from the body 142. The center of the joint portion 1441 is provided with a square button hole 1445. The button hole 1445 is stamped to prevent the buckle piece 144 from being deformed by completely punching. A three-sided punching and cutting method is adopted, so that a corresponding elastic piece 1447 is formed on the other side of the corresponding fastening hole 1445. The elastic piece 1447 is connected to the front end of the engaging portion 1441 near the abutting portion 1442, and opens toward the body 142. The outer side of the 1425 extends obliquely. The abutting portion 1442 is formed to extend from a distal end of the engaging portion 1441 toward a side of the opening 1425 perpendicular to the engaging portion 1441. The engaging portion 1442 is also a rectangular ◎-shaped sheet body. The end of the abutting portion 1442 extends from the end of the abutting portion 1442 toward the adjacent front heat radiating fin 140 in a direction perpendicular to the abutting portion 1442. The engaging portion 1443 and the engaging portion 1441 are formed. They are substantially parallel and have a certain height difference, which is the height of the abutting portion 1442. A fastening hook 1448 is disposed on the fastening portion 1443. The top end of the fastening hook 1448 is adjacent to the end of the fastening portion 1443, and the bottom end thereof is formed to extend obliquely toward the outer side of the opening 1425 toward the abutting portion 1442. The hook 1448 is identical in structure to the shrapnel 1447 and is parallel. The fastening portion 1443 has a receiving hole 1446 corresponding to the other side of the fastening hook 1448. The hook 1144 and the receiving hole 1446 can be integrally formed by pressing, and the hook 1448 can be avoided in the receiving hole 1446 when being pressed and deformed. After the external force is removed, the buckle 1448 is restored and the deformation is outwardly convex. The hooks 1448 are hooked on the heat dissipation fins 140 and hooked into the fastening holes 1445 of the corresponding fastening pieces 144 of the previous heat dissipation fins 140. Referring to FIG. 5 and FIG. 6 together, in the assembly, the heat dissipation fins 140 are arranged in parallel, because the joint portion 1441 and the fastening portion 1443 have a height difference, and the fastening portion 1443 of the rear heat dissipation fin 140 is placed in the previous one. The outer side of the inner end 1440 of the joint portion 1441 of the heat dissipation fin 140 is biased by the rear heat dissipation fin 140 to move forward, and the end of the fastening portion 1443 of the rear heat dissipation fin 140 201008473 ♦ •, 1449 passes through the opening When the 1425 slides over the outer side of the inner end 1440 of the joint portion 1441 of the front fin, the hook 1448 comes into contact with the outer side of the inner end 1440 of the joint portion 1441, and the hook 1448 is elastically deformed to be inwardly retracted by the squeeze. In the receiving hole 1446, the entire engaging portion 1443 forms a flat plate and moves forward along the outer side of the engaging portion 1441. When the clasp 1448 slides to the engaging hole 1445 of the engaging portion 1441, the clasp 1448 is deformed and inserted into the buckle. In the hole 1445, the fastening portion 1443 of the rear heat dissipation fin 140 is superposed on the outer side of the joint portion 1441 of the front heat dissipation fin 140. Since the buckle 1448 is parallel to the elastic piece 1447, the rear heat dissipation fin 140 The clasp 1448 is stacked on the elastic piece 1447 of the previous heat sink fin 140The end 1449 of the engaging portion 1443 of the rear heat radiating fin 14 is abutted against the outer side of the abutting portion 1442 of the preceding heat radiating fin 14A. Therefore, the backward movement of the front heat dissipation fin 140 is restricted, and the hook 1448 hooked in the buckle hole 1445 limits the forward movement of the front heat dissipation fin 14 从而 to limit the front and rear of the first heat dissipation fin 14 The movement of the direction. Moreover, the four fastening pieces 144 of the rear heat dissipation fins 140 are respectively disposed on both sides of the main body 142 and are disposed in the opening 1425, thereby restricting the movement of the front heat dissipation fins 14 in the up, down, left, and right directions. 14〇 The movement in all directions is limited, so that all the fins 14〇 are firmly assembled into one. In this way, the assembly is convenient, and the heat sink 1〇 is firmly connected, and the prior art is prevented from disposing the fastening mechanism on the upper and lower ends of the heat sink, which affects the smoothness of the bottom end of the heat sink and affects the heat dissipation efficiency, and the heat dissipation effect is good. Moreover, since the clip 144 is located at the center of the body 142, the material is reduced in material cost compared to the prior art fastening mechanism at the edge of the heat sink. In addition, because the fan 90 is directly below the center of the rotor, that is, the rotor wheel is more likely to generate hot thirst, so that the heat is not easily dissipated, and the heat sink fin 14 accommodates the heat pipe% condensation 11 201008473 . The nearby temperature is higher, so that the two cleats 144 located near each perforation period are inclined from top to bottom toward the slot 1422 - facilitating the introduction of strong wind below the outer circumference of the fan 90 hub to the center of the body 142. At the high temperature position, the airflow is guided from the two sides of the heat dissipation fin 14 to the middle of the heat dissipation tab 140, thereby enhancing convection and accelerating heat dissipation. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. Equivalent modifications or variations made by persons skilled in the art and in the spirit of the present invention are intended to be included within the scope of the following claims.
