Therefore, the dustproof transition device 310 can be easily cleaned so that it is not allowed to be passed ^ The dust is blocked, which affects the flow of the gas A10. The heat-dissipating fan 150 is used to make the gas Mo in the notebook computer 1 be taken out of the notebook computer through the air outlet 13 after the waste heat is entrained. Details 9 201001145 Detailed description The computer 1 may include not only one fan, but each fan is preferably disposed at the most heat-prone place when the notebook computer 1 is in operation. The fan is, for example, a central processing unit adjacent to the pen computer 1 The position of the CPU or the hard disk (HD). The cooling fan 150 of the dustproof heat dissipation module 30 is disposed at the air outlet 130. The cooling fan 150 can discharge the waste heat A10 from the notebook computer 10 As for the flow of the gas A10, as shown in FIG. 1B, when the gas A10 enters the notebook computer 10, the dust filter 310 blocks the dust entrained by the gas A10 from the air inlet 110 to prevent dust from entering the notebook computer. 1 inside 'to ensure access to the notebook computer 1 is a clean gas A10. When the gas A10 flows through the dust-proof warning module 300 and the notebook computer 1 components, and entrained waste heat The heat dissipating fan 150 discharges the waste heat A10 through the air outlet 130 to the outside of the notebook computer 1 to achieve the effect of dissipating heat from the notebook computer 1. The detecting portion 330 of the dustproof warning module 300 can be disposed at the air inlet 110I. Or the air outlet 130. As shown in Fig. 1B, the detecting portion 330 of the embodiment is disposed at the air inlet 110. The detecting portion 330 is a micro electric mechanic for detecting the flow rate of the gas A10. System, MEMS). Preferably, the detecting portion 330 is a thermal inductance measuring MEMS. Please refer to FIG. 3, which is a schematic diagram of a detecting portion of a preferred embodiment of the present invention. The detecting portion 330 includes a substrate 331, a cavity 332, a conductive pad 333, an upper insulating plate 335, a lower insulating plate 336, and a thermal device 337. The cavity 332 is formed in the substrate 331. The lower insulating plate 336, the thermal insulator 337, the 201001145 upper insulating plate 335 and the conductive pad 333 are sequentially disposed on the substrate 331 corresponding to the position of the cavity 332. When the gas in the cavity 332 generates a temperature gradient (for example, when the cooling fan 150 of the embodiment operates to cause the gas A10 to flow), the thermal appliance 337 is sandwiched between the upper insulating plate 335 and the lower insulating plate 336. A voltage signal is generated by the Seebeck Effect, and the voltage signal is transmitted through the conductive pad 333. According to the above manner, the detecting unit 330 is capable of monitoring the state in which the gas A10 flows in the notebook computer 1. The notebook computer usually has more than one air inlet, and the detecting unit 330 is preferably disposed at the largest air inlet of the notebook computer 1. According to this method, the detecting unit 330 can accurately detect the change of the temperature gradient T10, so that the notebook computer 1 can operate with optimum performance. The processing unit 370 is electrically connected to the detecting unit 330 and the warning unit 35A. When the cooling fan 150 starts operating, the detecting portion 330 detects a temperature gradient T10 due to the flow of the gas A10. The detecting unit 330 generates a voltage signal νιο from the temperature gradient τιο and transmits it to the processing unit 370. The unit 370 obtains the flow rate of the gas A1〇 according to the voltage signal γ1〇, i. and compares the μ rate with the preset flow rate. When the flow rate corresponding to the voltage signal v 1 小于 is less than or equal to the preset flow rate, the processing unit 37 transmits an information Μ 10 to the warning portion 35 〇 to cause the warning portion 35 to generate a warning Wi · WiO. Alternatively, the preset flow rate may be first converted to a predetermined voltage, and the preset voltage is stored in the processing unit 37, and the processing unit 370 is, for example, a differentiator (interp〇lat 〇r). When the processing unit & 370 receives the voltage signal v1〇 from the detecting unit 330, the system compares the voltage (four) V10 with the preset voltage. When the voltage signal vl 〇 is less than or equal to the pre-command: 201001145 pressure, the processing unit 370 generates the information M10. After the processing unit 370 generates the information Μ10, the warning unit 350 issues the warning information W10 to the notebook computer 1. In this way, the notebook computer 1 is notified that the dustproof heat dissipation module 30 is in an abnormal state. When the user of the notebook computer 1 receives the warning message W10, the problem of the dust-proof heat-dissipating module 30 can be solved immediately, so that the notebook computer 1 is not subjected to more serious damage. Regarding the manner of issuing the warning information W10, as shown in Fig. 1, the notebook computer 1 may further include a speaker 15, an operating system 17, or a light emitting diode (LED) 19. Warning message W10 can be warned by using the hardware device or software program of Notebook 1. For example, the warning message W10 can be transmitted through the hardware device to cause the speaker 15 to emit a warning sound or to cause the light-emitting diode 19 to issue a warning light to remind the user that the dust-proof heat-dissipating module 13 is abnormal. The warning message W10 can also cause a warning message to be generated in the operating system 17 of the notebook computer 10 through the software program, for example, jumping out of a warning window to remind the user that the dustproof heat dissipation module 30 is abnormal. I Hereinafter, a dustproof method of the dustproof heat dissipation module 13 of the embodiment of the present invention will be described. The dust-proof method is used to detect the dust content generated by the heat-dissipating gas in the notebook computer 1. The dust-proof method mainly includes the steps of detecting the flow rate of the gas, determining whether the flow rate is lower than the preset flow rate, and issuing a warning message that the dust amount reaches the upper limit when the flow rate is lower than the preset flow rate. Please refer to FIG. 1B and FIG. 4 simultaneously. FIG. 4 is a flow chart showing a dustproof method according to a preferred embodiment of the present invention. When the notebook computer 1 is turned on and the cooling fan 150 starts to operate, 12 201001145 gas A10, for example, air, enters the notebook computer 1 through the air inlet 110 from the outside. The dust entrained in the gas A10 outside the notebook computer 1 is isolated from the notebook computer 1 by the dust filter 310 by the dust filter 310 provided at the air inlet 110. Only the clean gas A10 can enter the notebook computer 1 through the air inlet 110. The detecting portion 330 is here, for example, a MEMS of thermal inductance measured at the air inlet 110. The gas A10 is incorporated in the notebook computer 10, and a temperature gradient T10 is generated at the air inlet 110. Step S11 is to generate a voltage signal V10 by using a MEMS transmission temperature gradient T10 " measured by thermal inductance. Then, in step S13, the processing unit 370 obtains a corresponding flow rate according to the voltage signal V10 generated by the detecting unit 330. Thereby, the flow rate of the gas A10 in the notebook computer 10 is obtained. Next, in step S15, the processing unit 370 determines whether the flow rate is lower than the preset flow rate. If so, it means that the amount of dust at the air inlet 110 has reached the upper limit, and the dust filter 310 has been blocked by dust. The cooling fan 150 does not smoothly discharge the waste heat generated by the notebook computer 1 to the notebook computer 1 . If not, it indicates that the dustproof heat dissipation module 30 is operating normally. In step S15, if the result of "YES" is obtained, step S17 is performed, and if not, the flow rate of the gas crucible 10 is continuously monitored in step S15. Further, in step S17, when the flow rate is lower than the preset flow rate, the warning information W10 of the upper limit of the amount of dust is emitted. In detail, when the flow rate is lower than the preset flow rate, the processing unit 370 transmits the message Μ10 to the warning unit 350, and the warning unit 350 issues the warning information W10 to the notebook computer 10. The notebook computer 10 can be passed through. The sound is emitted from the eight-pole body 19, or the warning light is emitted through the operating system 17, for example, jumping out of the warning window in the operating system 17 to inform the user that the dust-proof heat-dissipating module 13 is abnormal. The dust-proof heat-dissipating module disclosed in the above embodiments of the present invention and the notebook computer and the dust-proof method using the same, the fan externally brings the gas outside the computer into the computer, and after the gas enters the waste heat generated by the computer, the fan passes through the fan. The air outlet is taken away from the computer to prevent the computer from overheating. In addition, the five embodiments of the present invention are provided with a dust-proof filter and a detecting portion of the micro-product system at the air inlet. The dust filter is used to isolate the dirt entrained by the external gas from the outside of the computer, the detecting portion detects the flow rate of the gas at the air inlet, and determines that the dust filter is notified when the flow rate is lower than the preset flow rate. It is dusty or dirty and can no longer be used effectively. Users can use this information to replace the new dust filter or remove the original dust filter to clean it. Therefore, in the embodiment of the present invention, the state of use of the detachable dust filter is determined by detecting the flow rate of the gas at the air inlet. The user can monitor the heat dissipation of the fan and know if it is necessary to clean the dust-proof heat sink. The dust-proof thermal module is optimally dissipated, allowing the notebook to maintain optimal performance and extend the life of the notebook. In the above, the present invention has been disclosed in the above preferred embodiments, but it is not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims. 14 201001145 [Simultaneous Description of the Drawings] Fig. 1A of the notebook computer is not intended to be in accordance with a preferred embodiment of the present invention.
