Description of the Invention: [Technical Field] The present invention relates to a heat dissipating device, and more particularly to a heat dissipating device for dissipating heat from an electronic component. [Prior Art] It is well known that electronic components such as a central processing unit generate a heat amount during operation. In order to prevent the electronic component from being heated up due to the accumulation of heat, the operation of the electronic component is unstable. The electronic component usually needs to be equipped with a device to assist in heat dissipation. The heat dissipating device generally includes a heat sink having a bottom plate for contacting the electronic component to absorb heat and a plurality of heat dissipating fins disposed on the bottom plate. To increase the heat dissipation capability of the heat sink, the heat sink further includes a fan that provides a strong convective flow to the heat sink. The fan is secured to the heat sink by a mounting bracket. The outermost fin of the heat sink is provided with a plurality of screw holes, and the solid truss is provided with a plurality of through holes corresponding to the screw holes of the fin, and a plurality of screws are screwed through the through holes of the fixing frame to the screw holes of the fin Inside, fix the mount to the heat sink. The fan is further secured to the heat sink by a screw lock to the mount. In the heat dissipating device, the fixing frame needs to be fixed to the heat sink by a plurality of screws, and the assembly is cumbersome. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a heat dissipating device that is simple to assemble. 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 base, a heat conducting wing extending from the base 6 1296365 / and a plurality of extending from the wing a second (four) piece, the two sides of the heat sink are provided with two positioning grooves, and the fixing frame comprises a fan fixing panel fixed to the wing portion and a connection of the panel of the 盥兮久兴. Positioning pieces. Compared with the prior art, the positioning piece of the fixing frame is directly positioned in the positioning groove of the heat sink, and the assembly of the fixing frame and the heat sink is simple. [Embodiment] 1 Referring to FIG. 1, the heat dissipating device is used for Dissipating heat generated by an electronic component (not shown) mounted on a circuit board (not shown). The heat sink includes a heat sink 10, a fan 30, and a holder 20 for fixing the fan 3 to the heat sink 10. The heat sink 10 is integrally formed of a metal material and includes a heat conducting portion and a plurality of heat radiating fins extending from the heat conducting portion. The heat conducting portion includes a base portion 110'. The bottom surface of the base portion 110 is in contact with the electronic component. The base portion of the top surface of the base portion is obliquely outwardly and upwardly extending from the two heat conducting wings 130. The two heat conducting wings 130 constitute a "V". "Shaped structure. The two wings 13 分为 divide the fin into three regions: two first fin regions between the base 110 and the wings 130, and a first tab region between the two wings 130. The first and second die regions respectively include a plurality of first and second fins 121 and 141. The fins of each fin region are parallel to each other. The fins of the first and second fin regions are perpendicular to each other. The first fin 121 extends horizontally outward from the outer side of the wing 130 parallel to the base 110. The second fin 141 extends upwardly from the base 110 on the inner side of the wing 130. The two wings 130 are respectively provided with a screw hole 131 on the front surface 7 1296365 thereof, and the two screw holes 131 are located on the same horizontal line. The two sides of the heat sink 10 are respectively provided with a vertical positioning groove 150 near the front surface thereof, and each positioning groove 150 penetrates the outermost second fin 141 and the outermost ends of the corresponding first fins 121. The fan mount 20 includes two separate brackets 200 secured to the front sides of the front surface of the heat sink 10. Each bracket 200 includes a main body portion 210 and a fixed panel 220 and a positioning piece 230 extending perpendicularly from opposite sides of the main body portion 210. The panel 220 is generally "C" shaped and includes a tab 221 on its upper portion and an ear tab 223 located at a lower portion thereof. The tab 221 and the tab 223 surround a "C" shaped slit (not shown). The tab 221 and the tab 223 are respectively provided with a screw hole 225 for fixing the fan 30. The tab 223 is provided with a through hole 227 at a screw hole 131 corresponding to the heat sink 10 above the screw hole 225. Referring to FIG. 2, when the heat sink 10 and the fixing frame 20 are assembled, the positioning piece 230 of the bracket 20 bracket 200 is inserted into the positioning groove 150 on both sides of the heat sink 10. The panel 220 of the bracket 200 passes through the through hole 227 through the screw 250. It is locked in the screw hole 131 of the wing portion 130 of the heat repairer 10 to be fixed to the front surface of the heat sink 10. The two panels 220 of the two brackets 200 are located on two sides of the front surface of the heat sink 10, and a vent (not labeled) corresponding to the fan 30 is formed therebetween. In this embodiment, the tab 221 of the panel 220 projects upwardly from the upper end of the second fin 141 of the heat sink 10. Referring to Figures 1 and 3, the fan 30 includes a rectangular frame 310 and an impeller 330 located within the frame 310. The four corners of the frame 310 corresponding to the fixing frame 20 are provided with four through holes 311. The four fixing members 350 are fixed to the screw holes 225 of the fixing frame 20 through the corresponding through holes 311, thereby fixing the fan 30. To 8 1296365 on the holder 20. A portion of the fan 30 corresponding to the tab 221 of the holder 20 protrudes from the upper end of the second fin 141 of the heat sink 10. The locating tabs 230 of the bracket 20 are positioned in the locating slots 150 to fix the mounting bracket 20 and the heat sink 10, as compared with the conventional technology. Simple, the secure assembly of the holder 20 and the heat sink 10 can be achieved by a screw 225.
