摘要: | 離子風扇設計中,所使用的高壓端電極形狀均為單根金屬針狀電極,相對應的接地端為金屬環或金屬網,本研究探討在以多根金屬針狀電極為高壓端的離子風扇,並且以環狀排列取代原本單根針狀電極至於中央的排列。另外驅動離子風扇所必備的高壓電供應器使用倍壓整流電路製成。此高壓電供應器以50個電解電容與二極體組成。實驗結果顯示在使用多種容值的電解電容組成高壓電供應器的電路時,可有效減低使用單種容值所造成的電壓降,確保電壓降情形不存在才能使高壓電供應器正常運作。而電極製作的部分,實驗結果顯示多根針狀電極環狀排列時,在測試電壓10.5kV的情況下,三根電極產生的風速為1.21m/s,大於六根電極產生的風速0.85m/s,而略少於單根電極至於中央的風速為1.23m/s。 A ion fan is consisted of a pair of electrodes between which generated ions with applied high voltages can drive the air flow. Most study use pin-to-plate or pin-to-ring as its electrodes to generate ion wind, which the pin is at high potential. However, it has been studied that if one put a ring near the high potential pin can increase the velocity of ion wind. This study investigate the high potential electrode’s shape by using multi-pin circle arrangement instead of single pin in the middle. Additionally, a high voltage power supply (HVPS) is necessary of the ion fan, this study use voltage multiplier circuit as the HVPS which consist of 50 electrolytic capacitors and diodes. The experiment showing that using different capacitance of electrolytic capacitors can decrease the voltage drop which appears in using single capacitance of electrolytic capacitors. Finally, the multi-pin circle arrangement using 3 pins has a velocity of 1.21 m/s which is larger than 0.85 m/s when using 6 pins and is slightly smaller than single pin in the middle which is 1.23 m/s while the supplying voltage was in 10.5kV. |
