The upper _heater fastening device can be used to reduce the manufacturing cost, and the timing can be reduced. In the timing of the dispensing device, only the handle is needed, the age is convenient and labor-saving, and the installation is located on both sides of the radiator. It is small, does not affect the heat dissipation area of the existing radiator, and also maintains the proper fastening force. [Embodiment] The first to second embodiments of the present invention are disclosed as an embodiment of the heat sink fastening device of the present invention, which comprises - a pair of fasteners 2G 'Lin-heating n 1G fixed to - heat-emitting electronic components (Fig. For example, the heat dissipation of the central processing unit (CPU) of the system is made of a metal having good thermal properties such as copper, metal, etc., which includes a plurality of heat dissipation fins 12; 20 includes a handle 22 and a buckle 24. In this embodiment, the heat sink 10 is fixed to the heat-generating electronic component by a fixing module 3, and the opposite sides of the fixing module 30 are formed with a bump 32, and the heat sink 1 includes a center. a column 14 which may be a solid structure or a hollow heat pipe structure to rapidly transfer heat by phase change of a working fluid (such as water). The heat sink fins 12 of the heat sink 10 The radiation is disposed outwardly from the cylinder 14. The heat-dissipating film 12 is integrally formed with the pillar 14 or is specifically bonded to the periphery of the cylinder 14 by giuing or welding 7 1271271. The heat dissipation fins 12 include a first heat dissipation fin 121 and a second heat dissipation fin 123, and the first heat dissipation fins 121 are located near the middle position and extend beyond the second heat dissipation fins 123 (ie, than the second heat dissipation fins) The fins 123 extend outwardly, and the first fins 121 are provided with perforations 1211 through the fin walls. In this embodiment, the handle 22 of each clip 20 includes a positioning end 221 and an operating end 223. The positioning end 221 is provided with a first rotating shaft 225; the handle 22 Comprising a top wall 227 and side walls 227 of the two opposite sides of the top wall 229 is formed extending, perpendicular to the side walls 229 and 227 of the top wall. In the embodiment, the buckles 24 of each of the fasteners 20 are in the form of a sheet, and the bottom edge of the fastening module 30 is provided with a buttonhole 242, and the top edge is connected to the handle 22. The connecting end of the locking leg 24 and the handle 22 is offset from the position of the rotating shaft 225. The fastening leg 24 includes a substrate 244 and two side plates 246 extending from opposite sides of the substrate 244. The 246 is perpendicular to the substrate 244. The fastening hole 242 is disposed on the substrate 244 of the fastening pin 24. The two side plates 246 further extend away from the fastening hole 242 and are bent into a c-shaped elastic portion 247. The elastic portion 247 is formed. The free end is connected to the positioning end 221 of the handle 22 by the second rotating shaft 248. The second rotating shaft 248 is located below the first rotating shaft 225. In addition, the bottom ends of the two side plates 246 further extend outwardly to form the lugs 249. . In operation, the heat sink 10 is placed on the fixed module 3, and the bumps 32 of the fixed module 30 are respectively located on opposite sides of the heat sink 10, and correspond to the first heat dissipation 121 of the heat sink 1 The handle 22 of each of the fasteners 20 is disposed on the portion of the first heat dissipation tab 121 that protrudes outside the second heat dissipation tab 123 by the first rotation shaft, and the rotation shaft 225 is worn through the first shaft. The first fins 121 are sandwiched by the two side walls 229 of the heat sink fins 121. The handles 2 are rotatable relative to the heat sink 1 around the first rotating shaft 225. The bumps of the group 3 are slid through the buttonholes 242 of the buckles 24, and the bumps 32 are loosely disposed on the buttonholes 242 when they are in the unfastened positions as shown in the third and fourth figures. . 1271271 When the operation end 223 of the handle 22 is pressed downward to rotate the handle n around the first rotating shaft 225, the second rotating shaft (ie, the connection point of the buckle 24 and the handle 22) also rotates around the first rotating shaft 225. At the same time, the buckle 24 is moved upward; as the handle 22 continues to rotate, the second shaft 248 rises above the first shaft 225. Since the bottom edge of the buckle 24 is fastened to the fixed module 30, the buckle 24 The c-shaped elastic portion 247 is elastically deformed by stretching to generate a fastening force; when the handle a is rotated to pass the "dead position" (ie, the force of the first-rotating shaft 225 and the second rotating shaft (10) against the handle a is in the same line When the position is as shown in the fifth and sixth figures, the handle 22 is received in the receiving space formed by the substrate of the buckle 24 and the side plate 246, and the handle 22 no longer has a tendency to rotate, that is, enters the fastening state. The bump 32 of the fixing module 30 and the buttonhole 242 of the buckle 24 are firmly fastened, and the heat sink 1 〇 is relatively stably buckled; in addition, the handle 22 is also at the fastening position. The lug 249 of the buckle 24 is fixed by a pin to prevent interference from external forces (ratio Button vibration or the like) caused by loose rebound off problems, has good retaining effect. So far, the embodiment has been described in detail with reference to the accompanying drawings, the heat sink fastening device has a simple structure, and the manufacturing cost can be effectively reduced; when the heat sink is fixed, only the handle needs to be rotated, and the operation is convenient and labor-saving; The fastening device is located on both sides of the radiator, which occupies less installation space during installation. The existing radiator does not need to vacate the installation space, and the heat dissipation area is set. The fastening device can also maintain the proper buckle. Together, and has a good anti-off effect. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application 4 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 spirit of the invention are intended to be included within the scope of the following claims.
