That is, it is applicable to a fan cluster including at least one fan inside the control electronic device on an electronic device. The electronic device is, for example, a personal computer or a terminal server. In addition, the electronic device further includes a processor.

Referring to FIG. 2, in this embodiment, the output power of the external power supply, which varies from 0 to 100, is obtained to obtain the change of the fan speed of the single fan under the output power of different external power sources. The maximum speed is up to 4420 rpm, and the rotational speed is 1535 rpm in the case where the output power of the external power source is zero.
之後,請參照圖1,於步驟S105中,確認每一風扇於電子裝置中,所個別對應的安裝位置。舉例而言,使用者可以自行設定每一風扇在電子裝置中的位置。圖3繪示為風扇位於電子裝置中的各個安裝位置示意簡圖。請參照圖3,風扇安裝位置(例如以電子裝置的主機操作面為基準)包括前方位置3a、後方位置3b、側面位置3c、上方位置3d、下方位置3e以及處理器位置3f。也就是使用者可以如上例,自行設定/指定每一風扇各自的安裝位置。Thereafter, referring to FIG. 1, in step S105, it is confirmed that each of the fans is in the electronic device, and the respective corresponding mounting positions. For example, the user can set the position of each fan in the electronic device. FIG. 3 is a schematic diagram showing various mounting positions of the fan in the electronic device. Referring to FIG. 3, the fan mounting position (for example, based on the host operating surface of the electronic device) includes a front position 3a, a rear position 3b, a side position 3c, an upper position 3d, a lower position 3e, and a processor position 3f. That is, the user can set/specify the respective installation positions of each fan by the above example.
接著,於步驟S111中,確認電子裝置的一工作模式。其中,上述工作模式包括一標準模式、一安靜模式或一風扇高效能模式。也就是使用者根據各人使用習慣,而設定電子裝置的工作模式。例如,當使用者偏好電子裝置在執行時具有較小的機器運作聲音時,則可以設定電子裝置的工作模式為安靜模式。另外,當使用者偏好電子裝置在高運轉效能下執行應用程式時,則可以設定電子裝置的工作模式為風扇高效能模式,藉由高效能運轉之風扇而達到散熱功效。Next, in step S111, an operation mode of the electronic device is confirmed. The above working mode includes a standard mode, a quiet mode or a fan high performance mode. That is, the user sets the working mode of the electronic device according to the usage habits of each person. For example, when the user prefers that the electronic device has a small machine operation sound when executed, the operating mode of the electronic device can be set to the quiet mode. In addition, when the user prefers the electronic device to execute the application under high running performance, the operating mode of the electronic device can be set to the fan high-efficiency mode, and the heat-dissipating effect can be achieved by the fan running efficiently.
之後,於步驟S115中,對於每一風扇,根據上述所獲得的風扇運轉資訊、功率輸出-風扇轉速參數、此風扇所對應的安裝位置以及所確認的電子裝置的工作模式,計算處理器的工作溫度與此風扇的風扇轉動功率之間的一溫度-功率對應參數。圖4繪示為根據本案一實施例的處理器的工作溫度與單一風扇的風扇轉動功率之間的一溫度-功率對應參數圖。請參照圖4,每一風扇所對應的溫度-功率對 應參數例如是每一風扇的風扇轉動功率對應處理器的工作溫度的一不連續參數曲線402。值得注意的是,不連續參數曲線包括至少一曲線斜率轉折點。此曲線斜率轉折點包括處理器的工作效能為50%所對應的風扇轉動功率與處理器的工作溫度(亦即圖4中的轉折點404)。Then, in step S115, for each fan, according to the obtained fan operation information, the power output-fan rotation speed parameter, the installation position corresponding to the fan, and the confirmed operation mode of the electronic device, the operation of the processor is calculated. A temperature-power corresponding parameter between the temperature and the fan's rotational power of the fan. 4 is a temperature-power corresponding parameter diagram between an operating temperature of a processor and a fan rotating power of a single fan according to an embodiment of the present invention. Please refer to Figure 4, the temperature-power pair corresponding to each fan The parameter should be, for example, a discontinuous parameter curve 402 corresponding to the operating temperature of the processor for the fan rotational power of each fan. It is worth noting that the discontinuous parameter curve includes at least one curve slope turning point. The curve inflection point of this curve includes the fan rotation power corresponding to the processor's operating efficiency of 50% and the operating temperature of the processor (ie, the turning point 404 in FIG. 4).
舉例而言,處理器的工作溫度低於處理器的工作效能為50%所對應的轉折點404時,風扇轉動功率對應處理器的工作溫度的參數曲線的斜率小於工作溫度高於轉折點404的風扇轉動功率對應處理器的工作溫度的參數曲線的斜率。也就是,在處理器工作溫度低於轉折點404時,工作溫度的變化所導致的風扇轉動功率變化量較小。亦即為應變工作溫度升高,風扇轉動功率變化量無須太高,即可達成使用者所偏好的電子裝置的工作模式所需求的散熱功效。For example, when the operating temperature of the processor is lower than the turning point 404 corresponding to the working performance of the processor being 50%, the slope of the parameter curve of the fan rotating power corresponding to the operating temperature of the processor is smaller than the fan rotation of the working temperature higher than the turning point 404. The slope of the power curve corresponding to the operating temperature of the processor. That is, when the operating temperature of the processor is lower than the turning point 404, the amount of change in the rotational power of the fan caused by the change in the operating temperature is small. That is to say, the strain working temperature is increased, and the variation of the fan rotational power does not need to be too high, so that the heat dissipation effect required by the operating mode of the electronic device preferred by the user can be achieved.
而在處理器工作溫度高於轉折點404時,工作溫度的變化所導致的風扇轉動功率變化量較大。亦即為應變工作溫度升高,風扇轉動功率變化量提高,才能達成較佳的散熱功效。更明確的說,根據每個風扇各自的操作特性(風扇運轉資訊、功率輸出-風扇轉速參數)、風扇安裝位置以及電子裝置工作模式,隨工作溫度變化而智慧型的調整電子裝置的每一個風扇的風扇轉動功率,以更適切使用者所偏好的電子裝置工作模式,達到更省電節能的效果。When the operating temperature of the processor is higher than the turning point 404, the change in the rotational power of the fan caused by the change in the operating temperature is large. That is to say, the strain working temperature is increased, and the variation of the fan rotating power is increased to achieve better heat dissipation. More specifically, according to the respective operating characteristics of each fan (fan operation information, power output - fan speed parameter), fan installation position, and electronic device operating mode, each fan of the electronic device is intelligently adjusted as the operating temperature changes. The fan rotates the power to better suit the user's preferred electronic device operating mode, achieving a more energy-saving and energy-saving effect.
繼之,於步驟S121中,根據每一風扇所對應的溫度-功率對應參數,於電子裝置的一運轉狀態下,控制每一風 扇。也就是處理器根據所接收到的溫度偵測訊息(例如是以一溫度偵測器偵測處理器的一工作溫度),並根據每個風扇所對應的溫度-功率對應參數,自動調整每一風扇的轉動功率。Then, in step S121, according to the temperature-power corresponding parameter corresponding to each fan, each wind is controlled in an operating state of the electronic device. fan. That is, the processor detects the message according to the received temperature (for example, detecting a working temperature of the processor by a temperature detector), and automatically adjusting each according to the temperature-power corresponding parameter corresponding to each fan. The rotational power of the fan.

The temperature corresponds to the temperature-power parameter of each fan. However, the invention is not limited thereto. In another embodiment, after the calibration procedure (step S101) and the confirmation of the position of the fan (step S105), the fan operation information, the power output-fan speed parameter of each fan obtained, and the corresponding The installation location initially calculates the temperature-power corresponding parameter between the operating temperature of the processor and the fan rotational power of each fan. Next, after confirming the operation mode of the electronic device (step S111), the temperature-power corresponding parameter between the operating temperature of the processor and the fan rotation power of each fan is fine-tuned according to the set operation mode of the electronic device.
此外,於上述實施例中,使用者在自行組裝電子裝置時,可藉由所述的風扇控制方法,根據個人需求與各個風扇性能,將風扇安裝於電子裝置中的各個部位,而可發揮各個風扇的最佳效果。然而,本案並不受限於此。本案亦可以應用於當使用者變更至少一風扇或是電子裝置的工作模式時,重新控制的每一風扇的運轉。In addition, in the above embodiment, when the user assembles the electronic device by himself, the fan control method can be used to install the fan in various parts of the electronic device according to individual needs and performance of each fan, thereby The best effect of the fan. However, the case is not limited to this. The present invention can also be applied to the operation of each fan that is re-controlled when the user changes the working mode of at least one of the fans or the electronic device.
