Description

Flywheel Energy Storage Fan

本創作有關於一種飛輪儲能風扇，尤指一種可達到節能省電的飛輪儲能風扇。This creation is about a flywheel energy storage fan, especially a flywheel energy storage fan that can achieve energy saving and power saving.

現今的資訊通訊設備為了進行有效節能，多會控制尖峰與離峰時段內部散熱風扇有不同的轉速來因應不同期間的散熱需求。習知散熱風扇主要是透過主機板的一處理器直接做電壓輸出控制或利用脈波寬度調變(PWM)來調控風扇的加速或減速。而現有習知的散熱風扇內部的馬達為電動機設計，電動機主要是受通電後直接將電能轉換成風扇的機械能，以驅動散熱風扇旋轉產生氣流對發熱元件強制散熱。但卻延伸另一問題，習知散熱風扇只能單方向的把電能轉換為機械能，使得散熱風扇在降速過程的能量是無法有效再利用的，以導致能量直接白白損失而造成浪費，進而無法達到節能省電的效果。In order to effectively save energy, today's information and communication equipment often controls the internal cooling fans at different peak and off-peak periods to have different rotation speeds to meet the cooling requirements of different periods. The conventional cooling fan mainly uses a processor of the motherboard to directly perform voltage output control or use pulse width modulation (PWM) to regulate the acceleration or deceleration of the fan. The motor inside the existing conventional cooling fan is designed as a motor. The motor is mainly used to directly convert electrical energy into the mechanical energy of the fan after being energized, so as to drive the cooling fan to generate airflow to forcibly dissipate the heating element. However, it extends another problem. It is known that the cooling fan can only convert electrical energy into mechanical energy in one direction, so that the energy of the cooling fan during the speed-down process cannot be effectively reused, resulting in direct energy loss and waste. Can not achieve the effect of energy saving.

該扇輪2041內設有一收容孔20413，該收容孔20413用以收容一第一轉子軸承2051，該第一、二轉子軸承2051、2052與第一、二軸承3021、3022是在同一旋轉軸2044線上，以與對應該旋轉軸2044相樞設，令該第一、二轉子軸承2051、2052與第一、二軸承3021、3022用以支撐該風扇轉子204。並該扇輪2041更具有複數葉片20411及一輪轂20412，該等葉片20411環設在該輪轂20412的外周側上，該磁性件2043(如磁鐵或永久磁鐵)設於該輪轂20412之內側，且面對於該中柱部105上的風扇定子201。該飛輪能量儲存裝置30係與風扇轉子204是位於同一旋轉軸2044上，該飛輪能量儲存裝置30設有一飛輪旋轉體301，該飛輪旋轉體301於本實施例表示為一金屬材質(如何金剛材質、鐵材質、鈦合金材質或其他金屬材質)，但並不侷限於此，於具體實施時，該飛輪旋轉體301可選擇為一複合材質(如碳纖維與樹脂複合材質)、塑膠材質或陶瓷材質。其中該飛輪能量儲存裝置30的尺寸大小可大於、等於或小於該風扇電機20的尺寸大小。
該飛輪旋轉體301設於該真空腔室103內的旋轉軸2044上，且該飛輪旋轉體301於本實施例表示大致呈一圓盤狀，該飛輪旋轉體301係用以在風扇電機20為電動機驅動下使該飛輪旋轉體301加速在高速旋轉下，將能量以旋轉動能 (或稱機械能)儲存，或是在該風扇電機20為發電機運行下利用該飛輪旋轉體301釋放能量帶動發電機旋轉且逐漸降速的同時，可將動能轉化為電能提供給該風扇電機20為電動機繼續使用，藉以使能量有效利用提升最大效益。在一實施例，該飛輪旋轉體301為大致呈一薄輪環或一中空圓盤狀或其他形狀(如帶輪轂20412平圓盤狀)。在另一實施例，該飛輪旋轉體可透過一軸承(如機械軸承或磁浮軸承)樞設在該旋轉軸上。

因此，透過本創作此飛輪儲能風扇1的設計，使得有效達到節能省電及能量可有利用的效果。 The above-mentioned purpose of this creation and its structural and functional characteristics will be explained according to the preferred embodiments of the drawings.
