Description of the Invention: [Technical Field of the Invention] The present invention relates to a heat dissipating device, which is characterized in that it is reduced. (D) in the electronic element [Prior Art] As we all know, the central processor 箄 Rayfu is a lot of heat. In order to prevent the electronic component from being determined by the heat =::r, the conventional heat sink comprises a heat sink, the heat sink == the heat sinking plate of the component and the plurality of heat sinks disposed on the wire are still the heat sink The heat dissipation capability, *'' 枇 (4) V / political heating device also includes a fan that supplies a strong convection airflow to the heat sink. The fan is fixed to the heater through the holder. The outermost piece of the heat sink is provided with a plurality of screw holes, and the screw hole of the fixed piece should be provided with a plurality of through holes, and the plurality of screws (4) are screwed into the screw holes of the n pieces through the fixed hole. And fix the mount to the heat sink. The fan is further locked to the fixing frame by a screw to dissipate heat relative to the heat dissipation device. The fixing frame needs to be fixed to the heat sink by a plurality of screws, and the assembly between the fan and the heat sink is cumbersome. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a heat dissipating device that is convenient to assemble. The heat dissipating device comprises a heat sink, a fan and a fixing frame for fixing the fan to the heat sink, the heat sink comprising a bottom portion and a plurality of heat dissipating fins extending from the bottom portion 6200813387, the heat sink is opposite The outermost fin is provided with two positioning slots, and the fixing frame includes a fixing panel that carries the fan and a main body portion that is connected to the fixing panel and is positioned in the positioning slot. The main body portion is provided with a card to the heat sink. Positioning portion in the positioning groove. Compared with the prior art, the positioning portion of the fixing frame of the present invention is directly positioned in the positioning groove of the heat sink, so that the assembly of the fixing frame and the heat sink is simple and convenient. [Embodiment] _ Referring to FIG. 1, the heat sink includes a heat sink 10, a fan 30, and a holder 20 for fixing the fan 30 to the heat sink 10. The heat sink 10 is integrally formed of a metal material and includes a bottom portion 12 and a plurality of heat dissipation fins 14 extending from the bottom portion 12. The bottom surface of the bottom portion 12 is in contact with an electronic component (not shown) to absorb heat. The outermost fin 14 of the heat sink 10 includes a support section 140 extending from the bottom portion 12 and a curved section 142 extending upward from the top edge of the support section 140. The support section _140 gradually increases in thickness during its upward extension. As shown, 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 holder 20. The outer side surfaces of the outermost fins 14 of the heat sink 10 are respectively provided with a positioning groove 16, and each positioning groove 16 extends along the lateral direction of the outermost heat radiating fins 14. The positioning groove 16 is disposed at the junction of the support section 140 and the curved section 142. The holder 20 includes two separate brackets 200 that are secured to the top and sides of the heat sink 10. Each bracket 200 includes a main body portion 210 and a fixed panel 220 that is bent and extended from the side of the main body portion 210. The main body portion 210 has a shape of a moment 200813387, and a pair of positioning portions 212 are formed on the inner side surface thereof. The two opposite sides of the fixed panel 220 are respectively provided with a pair of screw holes 222 for fixing the fan 30, and the edges of the two fixing plates 220 are adjacent to each other, and an arcuate notch 224 is formed between the two screw holes 222 to facilitate the airflow generated by the fan 30. by. 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 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 heat radiating 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 2 (10). 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. However, the above is only a preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims.
