Description of the Invention: [Technical Field] The present invention relates to a heat dissipating device for a heat dissipating device. In particular, it refers to an electronic element. [Prior Art] / It is known that central processing electronics produce large heat during operation. In order to prevent the electronic component from being heated due to the accumulation of heat, which causes its operation to be unstable, the electronic component usually needs to be installed to assist in heat dissipation. The heat sink includes a heat sink having a bottom plate for contacting the heat absorption of the electronic component and a plurality of heat radiating fins disposed on the bottom plate. In order to improve the heat dissipation capability of the heat sink, the heat sink further includes a fan that provides a strong convection "airflow" to the heat sink. The stomach fan is fixed to the heat sink through a fixing frame. The outermost fin of the heat sink is provided. The utility model has a plurality of screw holes, wherein the fixing frame is provided with a plurality of through holes corresponding to the screw holes of the fins, and the plurality of screws are screwed into the screw holes of the fins through the through holes of the fixing frame, and the fixing frame is fixed to the heat sink The fan is further fixed to the heat sink by screwing on the fixing frame. In the heat dissipating device, the fixing frame needs to be fixed to the heat sink by more screws, and the assembly between the fan and the heat sink is cumbersome. In view of the above, it is necessary to provide a heat dissipating device with a convenient assembly. A heat dissipating device includes a heat sink, a fan and a fixing frame for fixing the fan to the heat sink, the heat sink including a bottom portion from the bottom 6 • 1304468 • a plurality of extended fins that have a second positioning slot opposite the outermost heat dissipating tab, the holder including a fixed panel carrying the fan and The main body portion of the fixing plate is connected to and positioned in the positioning groove, and the main body portion is provided with a positioning portion that is engaged with the positioning groove of the heat sink. Compared with the prior art, the positioning portion of the fixing frame of the invention is directly positioned. In the positioning groove of the heat sink, the assembly of the fixing frame and the heat sink is simple and convenient. _ [Embodiment] Referring to FIG. 1 , the heat dissipation device includes a heat sink 10 , a fan 3 , and a fan The fixing bracket 2 is fixed to the heat sink 1 . The heat sink 10 is integrally formed of a metal material and includes a bottom portion 12 and a plurality of heat radiating fins 14 extending from the bottom portion 12. The bottom surface of the bottom portion 12 and the electrons An element (not shown) contacts to absorb heat. The outermost fin 14 of the heat sink 1 includes a support section 14 extending from the bottom 12 and a curved section extending upward from the top edge of the support #140. The branch section 140 is gradually reduced in thickness during its upward extension. The curved section 142 has an auricular cross section, and the outer side of the curved section 142 is provided with a slope 144 for facilitating engagement with the fixing frame 2 。. 1〇 two outermost heat dissipation The outer side of the sheet 14 is respectively provided with a positioning groove 16 , and each positioning groove 16 extends along the lateral direction of the outermost heat dissipation fin 14 . The positioning groove 16 is disposed at the junction of the support section 14 〇 and the curved section 142 . 20 includes two separate brackets 200 fixed to the top and sides of the heat sink 10. Each bracket 2 includes a main body portion 21A and a fixed panel 220 bent and extended from the side of the main body portion 210. 210 is a moment 7 • 1304468. The shape of the sheet is formed on the inner side surface thereof with a pair of positioning portions 212. The two fixing panels 220 are respectively provided with one pair of screw holes 222 for fixing the fan 30, and the two fixing © plates 220 are adjacent to each other. An arcuate recess 224 is formed between the two screw holes 222 to facilitate the passage of the airflow generated by the fan 30. The four corners of the frame 32 of the fan 30 are provided with perforations 320 corresponding to the screw holes 222 of the fixed panel 220. Referring to FIG. 2 and FIG. 3 , when the heat sink 10 is assembled with the fixing frame 20 , the bottom portion of the main body portion 210 of the bracket 200 of the fixing frame 20 is inclined to slide over the inclined surface 144 of the outermost side of the heat dissipation fin 14 and overcomes the outermost heat dissipation. The fins 14 are plastically deformed and inserted into the positioning grooves 16 on both sides of the heat sink 10. The positioning portion 212 of the main body portion 210 is caught in the positioning groove 16. Referring to FIG. 1 , the four fixing members 40 , such as screws, pass through the corresponding through holes 320 of the fan 30 and are screwed into the screw holes 222 of the two fixing panels 220 to fix the fan 30 to the fixing frame 20 , so that the fan 30 is placed thereon. The top of the heat sink 10. The fan 30 forms a φ vent (not shown) corresponding to the fixed panel 220 of the two brackets 200. The positioning portion 212 of the bracket 200 of the mounting bracket 20 is positioned in the positioning slot 16 so that the fixing bracket 20 and the heat sink 10 are disposed. Simple to fix and easy to assemble. It can be understood that the fixing frame 20 can also be integrally formed as a whole. The positioning portion 212 is disposed as a ridge in the embodiment, and can also be a positioning component for positioning functions such as a bump, a protrusion, and a positioning piece. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
