Description of the Invention: [Technical Field] [0001] The present invention relates to a heat sink. [Prior Art] [0002] Conventionally, a fan frame can usually only be equipped with a fan of a corresponding size, and a fan of a different size and a different number cannot be installed to meet the heat dissipation requirement. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a heat dissipating device capable of fixing a plurality of fans. 0004 [0004] A heat dissipating device includes a fixing frame and a plurality of fans mounted on the fixing frame, the fixing frame includes a base and a plurality of posts extending in the same direction from the middle of the base, the bases are respectively opened at the four corners a perforation, each of the cylinders is recessed with an annular groove at the adjacent end, each fan includes two end walls, and the two end walls respectively define a perforation at corresponding positions of the four corners, and the posts correspond to a corner of the fan The perforations on the wall of the two ends, a ring buckle is inserted into the annular groove of the post, and the plurality of screws can pass through the Q hole at the four corners of the base and lock into the corresponding perforations of the fans. [0005] Compared with the prior art, the heat dissipating device protrudes from the middle of the base by a plurality of posts that can pass through the perforations of the fan, so as to conveniently fix the plurality of fans. Embodiments [0006] Referring to FIG. 1, a heat dissipating device of the present invention includes a mounting bracket 20 and four fans 10 mounted on the mounting bracket 20. The holder 20 includes a base 22 and a buckle 30. [0008] The base 22 is a quadrilateral frame, and a perforation 100106576 is formed at the four corners, form number A0101, page 3/10 pages, 1002011223-0 201235825 220, and a spoke having a "ten" shape is arranged in the middle. Ventilation part 260 of 260. A square support 262 is provided at the center of the spokes 206 (i.e., at the intersection). The four corners of the support table 262 respectively extend to form a post 24. Each of the posts 24 has an annular groove 240 recessed adjacent the end. A support piece 264 is disposed on each of the four ends of the spoke 260 adjacent to the base 22, and two spacer posts 266 are protruded from each of the support pieces 264. [002] The buckle 30 has a frame with an opening 300 on one side, and the buckle 30 has an operation portion 30 2 protruding outward from one side of the opening 300. [0010] Each of the fans 10 includes two opposite end walls 12, and the end walls 12 define a perforation 14 at a corresponding position of the four corners. [0011] Please refer to FIG. 2, when assembling, the two through holes 14 of each fan 10 are facing the one of the posts 24, so that the post 24 passes through the two through holes 14, and the annular groove 240 of the post 24 extends. A perforation 14 is provided away from the base 22. The two perforations 14 of the fan 10 adjacent to the end wall 12 of the base 22 are correspondingly locked to the two locking posts 2 66 of the base 22, and the other perforations 14 are perforated 220 to one of the bases 22. The two sides of the opening 300 of the buckle 30 are elastically deformed and sleeved at the ends of the posts 24, and the buckle 30 is released, so that the buckle 30 is deformed and locked. The annular groove 240 of the post 24 prevents the fans 10 from coming off the holder 20. Referring to FIG. 3, the plurality of screws 40 are correspondingly disposed through the perforations in a chassis 50, the through holes 220 of the base 22, and the corresponding through holes 14 of the fans 10, and the heat dissipating device is mounted on the chassis 50. [0013] When the fans 10 are disassembled, the screws 40 are released, and the operating portion 302 of the buckle 30 is operated to open the buckle 30 elastically, and the buckle 100106576 is removed. Form No. A0101 No. 4 Page 10 of 1002011223-0 201235825 30, these fans 10 can be removed. [0014] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed 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 in light of the present invention are intended to be included within the scope of the following claims.
