INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a heat sink, and more particularly to a heat sink having a dust removing function. [Prior Art] In recent years, with the rapid advancement of computer technology, the speed of computer operation has been continuously improved, and the power of the electronic components inside the computer mainframe has been continuously rising, in order to prevent the electronic components of the computer (4) from overheating. Causes temporary or permanent failure of electronic components, and must provide sufficient heat dissipation to the electronic components inside the computer. In general, the heat sink is mainly composed of a fan, a cooling fins and a heat pipe. The heat sink fin group is disposed at the air outlet of the fan and connected to the heat pipe to absorb waste heat conducted by the heat pipe. The heat sink fin group is composed of a plurality of metal sheets arranged in parallel, and a gap is provided between adjacent metal sheets to provide waste heat to escape into the air via convection. Therefore, when the fan is in the operating state U, the cooling airflow can flow to the heat dissipation fin group through the air outlet, and through the gap between the metal sheets, the waste heat is discharged out of the body by convection, thereby reducing the operating temperature of the internal electronic components. . It is worth noting that when the heat sink is used for a long time, the dust in the air gradually accumulates between the metal sheets of the heat sink fin group. If it is not cleaned, if too much dust accumulates on the metal sheet, it is easy for the wind blown by the fan to remove the waste heat from the heat sink fin group, resulting in a significant reduction in the heat dissipation capability of the heat sink. 200823636 IPD060578TW 22295twf.doc/006 SUMMARY OF THE INVENTION An object of the present invention is to provide a heat sink having a dust removing function for removing dust accumulated on a heat sink fin group. The present invention provides a heat sink having a dust removing function including a heat conducting component and at least one vibrator. The heat conducting component includes a plurality of isometric 'arranged metal crucibles, and the vibrating coupling reduces the conductive components to provide a source of motion to the metal sheets. The teachings suggest another heat sink with a dust removal function, which includes a second and at least a vibrator. The heat conducting component includes a plurality of two aligned metal sheets ' and the vibrations are disposed in the hot material to provide a non-contact vibration source to the metal sheets. In accordance with the present invention, the vibrator includes a piezoelectric element and the electromechanical element is deformed to generate a source of vibration. In accordance with an embodiment of the invention, the vibrator includes an eccentric motor, and the partial-horse phase-eccentricity and the component rotation cause a vibration source. According to the present invention, in the embodiment, the heat sink further includes a coupling to the actuator for controlling the vibration, and the timer may include a timer and a timing; and the time for controlling the vibration source. β. The ten-those spreader provides the handle-hand---------- One end of the heat pipe is connected to the metal piece, and the other is - so that the heat generated by the heat source is transmitted to the heat source through the heat pipe, the group, the ==:= device is further ^^^ the air outlet for providing a cooling 200823636 IPD060578TW 22295twf, d〇c/〇〇6 Airflow between these metal sheets. In this case, due to the use of a heat sink with a dust removal function, the metal sheet dusted off by the morning motion. Since the heat sink can automatically clean the dust on the metal sheet at regular or irregular days, the airflow generated by the fan can quickly remove the waste heat from the metal sheet, thereby significantly increasing the heat dissipation capability of the heat sink. The above and other objects, features and advantages of the present invention will become more apparent and understood. [Embodiment] Please refer to FIG. 1, which is a schematic diagram of a heat sink with a dust removing function according to an embodiment of the invention. The heat sink 100 mainly includes a heat conducting component 110 to = at least one vibrator 120, and the heat conducting component 110 provides a high heat generating amount of 70 pieces of heat to reduce the operation of the electronic components inside the system. The heat conduction component 11 is generally made of a highly thermally conductive metal material such as copper or aluminum, which can be disposed on an electronic component or connected to an air-cooled thermal module or a water-cooled heat dissipation module inside the system to achieve temperature reduction. purpose. In the present embodiment, the heat conducting component 110 includes a plurality of isotropically aligned metal sheets 112, and the regularly arranged metal sheets n2 are stacked one on another and spaced apart to increase the heat dissipating area of the heat conducting component. The metal sheets '112 are disposed, for example, at the air outlet 132 of the fan module 130, so that the cooling airflow generated by the fan module 30 can smoothly pass through the gap between the metal sheets ίο. Further, the heat conducting component 110 may further include a heat pipe 114 connected between the metal sheets 112 and a heat source 1 (e.g., an integrated circuit wafer). 200823636 IPD060578TW 22295twf.doc/006 The inner (four) of the heat pipe 114 is provided with a capillary structure for the cooling water to flow by the capillary phenomenon in the heat pipe 114 2 ' and can transfer the waste heat generated by the heat source ι 端 on the end of the heat pipe 114 to The metal tube ιΐ2 on the other end of the heat pipe 114 is used for the purpose of cooling. It should be noted that the vibrator 12G can generate a vibration source for lifting dust to prevent excessive accumulation of dust on the political surface of the metal sheet 112 and/or the heat pipe. As shown in Figure i, the shock can be directly placed on the hot mass assembly 11G, which can produce a morning source of contact =. Through the vibration of the brain 12 () itself, the metal piece 112 5 to = the vibration force', so that the dust on the metal piece 112 is shielded by the vibration. In the embodiment, the dust is easily accumulated between the mt i12 after a period of time. And/or between the metal piece 112 and the heat pipe 114, in particular, the portion of the fan module 13 is reduced, so that the position of the vibrator 12 is preferably close to the metal piece 112 of the fan module 13G. The result of the present embodiment is not limited to the preferred configuration points obtained by limiting the simulation or simulation of the present invention. Further, the number of the vibrators 120 may be selectively set to one or more. The outer fan module 13 () is disposed on the side of the metal piece 112, and generates a centrifugal force by π \ = (four), and the cold air outside the money passes through the air inlet (not, not 'in the same direction as the rotating shaft of the blade 134) Into, the blade 134 flows in the direction of rotation, and then flows from the air outlet 132 to the metal piece 112 aligned with the u. In the present embodiment, the normal vectors of the air inlet and the air outlet 132 are perpendicular to each other, but in another embodiment 200823636 IPD060578TW 22295twf.doc/006 t, the normal vectors of the air inlet and the air outlet 132 may be parallel to each other. of. Referring to FIG. 2, the vibrator 120 has, for example, a piezoelectric element 12A: it is configured to be assembled on the heat conducting component u of FIG. The piezoelectric element 120a is deformed by the piezoelectric effect, so that when the piezoelectric element is applied with an external input high voltage, a mechanical shock of the south frequency is generated, so that a vibration source can be generated. In addition, referring to Fig. 3, the vibrator 120 has, for example, an eccentric motor 12%. The centering motor 12Gb has an eccentric element 122, such as an eccentric cam or a biased mandrel. When the eccentric motor 12〇b inputs electric energy from the outside, by the high-speed rotation of the eccentric element I22, an eccentric vibration source can be generated so that dust accumulated on the metal piece 112 cannot be attached thereto and dropped. In addition to the specific implementation of the contact type vibration source generated by the piezoelectric element and the eccentric motor, the two agricultural vehicles can be disposed in the vicinity of the heat conduction group j cow 110 in a non-contact manner to generate a non-contact vibration source. . Referring to the figure, the flipping 11 is, for example, an ultrasonic wave generating H 12Ge, and the generated ultrasonic wave is transmitted by air to the heat conducting component 11A. By the fluctuation of the air, C, dust can no longer adhere to the surface of the metal piece 112 to generate a dust removal function. Since the frequency of the ultrasonic vibration source exceeds the frequency that can be received by the human ear, no noise is generated to the person. In addition, please refer to FIG. 1 , the vibrator 120 can cooperate with the controller 140 to generate functions such as automatic timing, starting and closing, so that the vibrator 12 is set to be automatically activated by the heat dissipation system or the electronic component. Turn on ' 2 automatically turns off when the cooling system or electronic components are off. Of course, the present invention can also set a hotkey or a built-in dust management unit in addition to the 200823636 IPD060578TW 22295twfd〇c/〇〇6 dust to inform the user, so that the user can select the dust according to the situation, the vibrator U0 can also The timer (not shown) is used to count the morning 120 & time for the morning source so that the controller 14 can set the working time of the dust removal. In summary, the present invention has been developed to provide a dust-removing heat sink that reduces the amount of dust adhering to the heat-conducting component, especially on the isotropically aligned metal sheets (heat-dissipating fin sets). The dust volume has an excellent reduction effect 'to avoid excessive dust accumulation on the outgoing metal sheet of the fan module' and affect the heat dissipation performance of the metal sheet. At the same time, the cooling airflow generated by the fan module can easily take away the waste heat on the metal sheet, so the heat dissipation capability of the radiator is relatively improved. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention to any of the ordinary skill in the art, and without departing from the spirit and scope of the invention, t may be modified and = The invention is based on the fact that the applicant has a special application.
