Abstract
Description
本發明係關於一種風扇。The present invention relates to a fan.
電子設備如電腦系統在系統斷電以後，內部的散熱風扇由於失去電源供應而停止轉動，此時系統內部殘餘的熱量只能透過機箱的被動散熱來釋放。在周圍環境溫度較高的情況下，這將造成系統內部溫度在關機後的一段時間內仍然較高，從而縮短電腦系統的使用壽命。After the electronic equipment such as the computer system is powered off, the internal cooling fan stops rotating due to the loss of power supply. At this time, the residual heat inside the system can only be released through the passive heat dissipation of the chassis. In the case of high ambient temperatures, this will cause the internal temperature of the system to remain high for a period of time after shutdown, thereby shortening the life of the computer system.
鑒於以上內容，有必要提供一種風扇，在系統斷電後仍然持續轉動一段時間以對電子設備進行散熱。In view of the above, it is necessary to provide a fan that continues to rotate for a period of time after the system is powered off to dissipate heat from the electronic device.

The controller includes a memory, a timer, and a control unit. The memory is configured to store a preset timing value. The timer is used to time the running time of the fan motor after the computer system is turned off. The controller is connected to the interface, the switch, the battery and the fan motor. The switch is connected to the battery, and the fan is connected to a motherboard through the interface. When the motherboard is powered normally, the control unit receives a voltage from the motherboard to the fan motor through the interface to control the fan motor to control the fan operation; when the motherboard is not working, the control unit will not Receiving a voltage from the motherboard, the control unit controls the switch to be turned on, so that the battery supplies a voltage to the fan motor through the switch and the controller to control the operation of the fan motor to control the fan operation, and The timer starts counting and when the timing reaches the preset timing value, the control unit controls the switch to be turned off to The battery stop providing voltage to the fan motor.
相較習知技術，該風扇可以在電腦系統斷電以後仍然持續轉動一段時間，對關機後機箱內殘餘的熱量進行主動散熱，從而可以延長電腦系統的使用壽命。Compared with the prior art, the fan can continue to rotate for a period of time after the computer system is powered off, and actively dissipates the residual heat in the chassis after the shutdown, thereby prolonging the service life of the computer system.
請參考圖1，本發明風扇100較佳實施方式包括一控制器10、一開關20、一蓄電池30、一風扇馬達40及一介面50。在本實施方式中，僅列出了該風扇100的部分元件，該風扇100上的其他元件與通常風扇上的其他元件相同，比如葉片等，在此不再贅述。該控制器10包括一記憶體11、一計時器12、一控制單元13及一充電單元14。該記憶體11用於存儲該蓄電池30的飽和電壓值及一預設計時值。該充電單元14用於在電腦系統工作時且該控制單元13偵測到該蓄電池30的電壓低於飽和電壓值時對該蓄電池30進行充電。該計時器12用於在電腦系統關機後對風扇馬達40的運行時間進行計時，以在計時時間到達該記憶體11中的預設計時值時使得控制單元13控制該風扇馬達40停止工作。Referring to FIG. 1 , a preferred embodiment of the fan 100 of the present invention includes a controller 10 , a switch 20 , a battery 30 , a fan motor 40 , and an interface 50 . In this embodiment, only some components of the fan 100 are listed. Other components on the fan 100 are the same as other components on the fan, such as blades, and the like, and details are not described herein. The controller 10 includes a memory 11, a timer 12, a control unit 13, and a charging unit 14. The memory 11 is configured to store a saturation voltage value of the battery 30 and a preset timing value. The charging unit 14 is configured to charge the battery 30 when the computer system is operating and the control unit 13 detects that the voltage of the battery 30 is lower than the saturation voltage value. The timer 12 is used to time the running time of the fan motor 40 after the computer system is turned off, so that the control unit 13 controls the fan motor 40 to stop working when the timing time reaches the preset timing value in the memory 11.
該控制器10連接該介面50、該開關20、該蓄電池30及該風扇馬達40。該開關20連接該蓄電池30。The controller 10 is connected to the interface 50, the switch 20, the battery 30, and the fan motor 40. The switch 20 is connected to the battery 30.
使用時，該風扇100透過其介面50連接一電腦主機板200。當該主機板200正常工作時，該控制單元13透過該介面50從該主機板200接收到電壓並輸出給該風扇馬達40，以控制風扇馬達40工作從而控制風扇100運行，同時，該控制器10偵測該蓄電池30的電壓並將其與存儲在記憶體11中的飽和電壓進行對比，若其低於飽和電壓，則該控制單元13控制該開關20導通，並通過該充電單元14為該蓄電池30進行充電，並在該蓄電池30的電壓到達飽和電壓值時控制該開關20截止，以停止對該蓄電池30充電。In use, the fan 100 is coupled to a computer motherboard 200 through its interface 50. When the motherboard 200 is working normally, the control unit 13 receives a voltage from the motherboard 200 through the interface 50 and outputs the voltage to the fan motor 40 to control the operation of the fan motor 40 to control the operation of the fan 100. Meanwhile, the controller 10 detecting the voltage of the battery 30 and comparing it with the saturation voltage stored in the memory 11, if it is lower than the saturation voltage, the control unit 13 controls the switch 20 to be turned on, and passes the charging unit 14 for the The battery 30 is charged, and the switch 20 is controlled to be turned off when the voltage of the battery 30 reaches a saturation voltage value to stop charging the battery 30.
當該主機板200不工作時，該控制器10將不會從該主機板200上接收到電壓，此時該控制單元13控制該開關20導通，從而使得該蓄電池30透過該開關20及該控制器10提供電壓給該風扇馬達40，以控制風扇馬達40工作從而控制該風扇100運行，同時該計時器12開始計時並在計時到達預設計時值時，該控制單元13控制該開關20截止，以使該蓄電池30停止提供電壓給該風扇馬達40。When the motherboard 200 is not working, the controller 10 will not receive a voltage from the motherboard 200, and the control unit 13 controls the switch 20 to be turned on, so that the battery 30 transmits the switch 20 and the control. The controller 10 supplies a voltage to the fan motor 40 to control the operation of the fan motor 40 to control the operation of the fan 100, while the timer 12 starts timing and the control unit 13 controls the switch 20 to be turned off when the timing reaches a preset timing value. The battery 30 is stopped from supplying a voltage to the fan motor 40.
該風扇100可以在電腦系統斷電以後仍然持續轉動一段時間，對關機後機箱內殘餘的熱量進行主動散熱，從而可以延長電腦系統的使用壽命。The fan 100 can continue to rotate for a period of time after the computer system is powered off, and actively dissipates the residual heat in the chassis after the shutdown, thereby prolonging the service life of the computer system.
