1872年，一個叫約瑟夫的法國人又研制出一種靠發(fā)條渦輪啟動，用齒輪鏈條裝置傳動的機械風(fēng)扇，這個風(fēng)扇比拜倫發(fā)明的機械風(fēng)扇精致多了，使用也方便一些。 </p> <p> 結(jié)構(gòu)： </p> <p> 轉(zhuǎn)子:由磁鐵、扇葉及軸組成;定子:有硅鋼片、線圈及軸承組成;控制電路:由 IC 感應(yīng)磁鐵 N .

風(fēng)扇轉(zhuǎn)運主要的部件就是軸承，時間長了缺乏潤滑油，這樣高速轉(zhuǎn)動時就會產(chǎn)生噪聲。因此，我們只需要在風(fēng)扇軸承上滴幾滴潤滑油，如果沒有使用縫紉機代替也可以。但是注意千萬不要使用食用油來替代，因為其顆粒比較大，容易對軸承產(chǎn)生傷害。 </p> <p> 折疊二、固定扇葉 </p> <p> 震動噪音亦是風(fēng)扇噪音的一個重要組成部分，因為葉片在軸承上的松動以及軸承磨損導(dǎo)致間隙變大等，因此只需要拆下分扇，把螺絲鈕緊，這樣牢牢固定之后，就不會再震動。 </p> <p> 折疊三、打磨扇葉 </p> <p> 另外使用質(zhì)量較差的散熱風(fēng)扇，在制作這類風(fēng)扇時由于工藝上的缺點，扇葉的重心可能沒有處在軸心上，形成""偏心""，使用時間一長，風(fēng)扇的""偏心""現(xiàn)象會變得越來越嚴(yán)重，這不僅會產(chǎn)生噪音，嚴(yán)重的還可能損壞CPU。對此，可以將共拆下來，然后用細(xì)線吊在其中心位置，待其靜止后看其向哪一方向下沉，把下沉的一端在砂輪上輕磨幾下，再進行測試，一直待風(fēng)扇能夠處在水平位置之后再將其安裝上去即可。 </p> <p> <br /> </p><p> 看運轉(zhuǎn)及調(diào)速性能:通電后將搖頭開關(guān)往復(fù)轉(zhuǎn)動數(shù)次，檢查是否失靈或裝配過緊，在這一過程中，風(fēng)扇機械傳動部分不應(yīng)該有異常噪聲。電風(fēng)扇在微、中、強風(fēng)運轉(zhuǎn)時，電機和扇葉都應(yīng)平穩(wěn)、震動小、噪聲較低。風(fēng)扇搖頭、停擺應(yīng)敏捷，無間歇、停滯和抖動現(xiàn)象，各擋轉(zhuǎn)速差別應(yīng)明顯，送風(fēng)角度越大越好。在風(fēng)扇停轉(zhuǎn)時，轉(zhuǎn)軸軸向間隙不超過0.5厘米，間隙過大，運轉(zhuǎn)時會引起軸向竄動并有撞擊聲。 </p> <p> 看是否漏電:電風(fēng)扇通電后，如果手觸碰有強烈麻電感，用試電筆測試，試電筆也會發(fā)光顯示，可判定外殼漏電，不可選用。電梯風(fēng)扇是放在哪個位置的？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

常見的風(fēng)扇扇葉截面曲線,一般基于Joukowski(茹科夫斯基,俄國有名的空氣動力學(xué)家,當(dāng)代航空科學(xué)的開拓者,提出了茹科夫斯基函數(shù),奠定了機翼空氣動力計算的理論基礎(chǔ))機翼截面曲線設(shè)計,再按照設(shè)計需要,根據(jù)葉片根部及端部與旋轉(zhuǎn)軸之夾角、根部及端部寬度等數(shù)據(jù)進行旋轉(zhuǎn)堆疊,形成三維扇葉曲面,并進行曲線擬合,終完成整個扇葉模型設(shè)計。 </p> <p> 扇葉的性能受到眾多參數(shù)的影響,如層疊高度、葉片曲率、葉片傾角、葉片間距、葉片厚度、葉片數(shù)目、葉片沖角、葉端間隙、葉片寬度、主軸直徑等等,且各參數(shù)間互相制約,關(guān)系復(fù)雜。不斷的調(diào)整各項參數(shù),尋找適合目標(biāo)工作要求的組合,便是進行扇葉設(shè)計的研究人員所從事的工作。若要將這些參數(shù)全部解釋清楚并加以分析,足以寫出幾篇博士論文了,但本文只是淺要分析風(fēng)冷散熱器的相關(guān)技術(shù),實無此必要,筆者也尚無此能力。

轉(zhuǎn)速是風(fēng)扇各項性能指標(biāo)的根本決定因素之一。 </p> <p> 轉(zhuǎn)速即風(fēng)扇扇葉在單位時間內(nèi)旋轉(zhuǎn)的周數(shù),單位一般為rpm,即rounds per minute-轉(zhuǎn)每分。轉(zhuǎn)速是風(fēng)扇容易測量的參數(shù),高轉(zhuǎn)速是各種風(fēng)扇力量的源泉,也是大噪音的根源。 </p> <p> 轉(zhuǎn)速基本上取決于風(fēng)扇采用的電機性能。 </p> <p> 只要確定了風(fēng)扇的物理規(guī)格、結(jié)構(gòu),各種性能就全部由轉(zhuǎn)速決定。轉(zhuǎn)速可以影響到風(fēng)速、風(fēng)量、風(fēng)壓、噪音、功率,甚至使用壽命。轉(zhuǎn)速越高,風(fēng)扇性能越強,即風(fēng)速越快,風(fēng)量越大,風(fēng)壓越大;同時,轉(zhuǎn)速高,摩擦、振動就多、噪音就大,軸承等損耗設(shè)備的壽命就短;轉(zhuǎn)速提高,電機消耗功率增大也是必然結(jié)果。
