If it is not scheduled in time:::, ,, and summer will seriously affect the normal operation of the central processing unit. To this end, the second pass is provided with a heat dissipating device on the top surface of the central processing unit for dissipating the heat dissipating device. The heat dissipating device usually includes a heat sink with good thermal conductivity, a fan and a fan for mounting the fan on the heat sink. Fan holder. As disclosed in Chinese Patent Publication No. CN 2605598, a heat dissipating device includes a heat sink, a fan, and two fixing members for fixing the fan to the heat sink, and the fixing member is fixed to the heat sink by screws. Two. In this way, drilling is required on the heat sink. The operation is troublesome when the mounting system is installed. In addition, the forced airflow blown by the fan easily flows away from the air outlets on both sides of the top of the heat sink, and the heat dissipation in the high heat region is insufficient. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a heat sink that can both guide the air and fix the fan. The heat management device comprises a heat sink, a fan and two fan fixing members for fixing the fan to the heat sink, the heat sink comprising a base and a plurality of heat dissipating fins extending from the crucible base, each of The fan fixing member comprises a 6 1312455 for infusing the main body portion of the outer side of the far fin and the solid portion of the main body portion of the fan fixing member. The wind deflecting plate is disposed; the fan is fixed to the fan Extending outwardly, the outermost two heat dissipating fins are oppositely formed with: a locking portion of the piece, wherein the two fan fixing members are stuck to each other? The load bearing portion of the paper fan, ...: is fixed to the heat sink. Compared with the prior art, the heat dissipating device of the present invention has the following advantages: the solid part is stuck between the fins, the lock of the fan fixing member is locked, and the screw is locked, and the zinc is selected as the further improvement of the invention. Each of the '. The part is perpendicular to the dilated film, and the main body of the feather fixing member is ',,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, : Vents, which enhances the heat dissipation of the heat sink base. β 里 K speed [Embodiment] ' = i shows that the heat sink of the present invention preferably includes a heat sink 1 , a fan 50 , and a fan n for fixing the heat sink 10 on the circuit board The buckle 20 (not shown) includes a susceptor u and a top surface extending from the top of the pedestal η; ΐ ΐ: a heat sink fin 15, the base 11 is substantially rectangular, and its top surface ^The central rain is low on both sides of the ridge. The upper edge of the heat sink fin 15 of the t portion is gradually lowered toward both sides. The heat-dissipating Korean films 15 are arranged in parallel with each other, and the two heat-dissipating fins located at the outermost side of the susceptor 11 are higher than the other heat-dissipating fins to form a support of the two-clamp fan fixing members 30 and 40 and the supporting fan 5 Board 12. The two support plates 12 extend perpendicularly toward the upper end edge to extend two longitudinally long plate-shaped carrying portions 17, which are substantially parallel to the base u and whose lower surface is slightly higher than the highest point of the political fins 15. The upper surface of the carrying portion 17 is used to carry the fan 50. The heat dissipating #15 and the two supporting plates 12 are provided with two side-by-side receiving slots 14 in the longitudinal direction, and the receiving slots 14 extend downward to the surface of the base 11 for the elastic arms 22 of the clips 20 to be placed therein. The second is accommodated in the slot 14. . . Referring to FIG. 2 and FIG. 3 together, the fan fixing members 3〇 and 4〇 are placed between the heat-receiving support plates 12 and across the top of the heat-dissipating fins 15 to make the heat-dissipating fins 15 top. The surrounding space is surrounded by the support plate 12 and the fan fixing members 30, 40' to reduce the loss of the fan 5 blown airflow. > The fan m stator 30 includes a sheet-like main body portion 32. The charm body portion 32 is disposed in a rectangular plate body having a length f between the inner surfaces of the two outer plates 12; the upper edge of the main body portion 32 extends vertically. a horizontal locking portion 33, the locking upper portion [3 upper surface abuts against the bottom surface of the bearing portion 17, thereby restricting the displacement of the fan fixing member in the ugly direction, and the lower edge of the main body portion 32 extends obliquely downwardly to a wind deflector 34. . The locking portion 33 has two fastening pieces 33 两端 at the two ends, and the fastening piece 33 has a threaded hole 332 for the fan 5 to _% on the four corners; the stomach=34 is in the shape of a plate and the body portion is At a certain angle to facilitate the wind guide, the C 34 and the locking portion 33 are respectively located on both sides of the main body portion %. The wind element 40 is substantially the same as the fan fixing member 3〇 except that the fan fixing member 40 is not provided with the air guiding plate 34 in the fan fixing member 30=adjacent to the fan element 4G including the fan fixing member 3q The main body portion 42, the locking portion 43, the j port H 4 u >« the sheet 430 and the threaded hole 432 on the cleat 430. The device 20 includes an elastic arm 22, a second member 21 placed at one end of the elastic arm, a second portion 23 placed at the other end of the elastic arm 22, and a female squat above the elastic arm 22 and the second buckle. The operation of the joint 23 is connected to the 8 1312455 portion 24. When installing, firstly, the elastic arm 22 of the buckle 20 is placed in the second receiving slot ', and then the locking parts % and 43 of the fan fixing member 3 〇 and 4 置于 are respectively placed on the radiator ίο 2 support plate. Between 12, the locking portions 33, 43 are in contact with the bottom surface of the supporting portion 17 of a supporting plate 12 by the upper ends of the two ends, and the middle portion of the locking portion can be pressed at the highest point in the middle of the heat dissipating fins 15. At this time, the fan solid=4^_section 33'43 is sandwiched between the two support plates 12 and the heat-dissipating fins' main body portions 32, 42 perpendicular to the heat-dissipating fins 15 and abutting on the outside of the teachings, ',, and . Then, the fan 5 is placed on the upper surface of the uploading portion 17 of the fan fixing member 30, 4, and the perforation 52 is aligned with the threaded hole 332 on the fan member 3, 40, and then 30^40, ^^ 33^ Locked. Thus, the fan 5G is locked to the heat sink 1 (), thereby joining the 固定 fixing members 30, 4 〇 and the heat sink 1 。. : = Directly fan the fan parts 3G, 4 () on the heat sink iq, = easy to install, avoiding the cumbersome operation of the lock screw. During the work, the second support plate 12 of the radiator and the fan fixing member enclose the top of the heat-dissipating H 1G, and the direct flow from the 'Wei flow to the high-heat zone at the bottom of the heat dissipation (four) takes away the heat dissipation to avoid the airflow from dissipating heat. The top of the device 1 leaks, the risk ^ the heat dissipation performance of the entire heat sink. In addition, the fan fixing member, the air plate 34, forcing the airflow to the other electronic capacitors and resistors on the circuit board increases the heat dissipation effect on the entire circuit system.
