風(fēng)扇工作方式：1、并聯(lián)風(fēng)扇:并聯(lián)的雙風(fēng)扇風(fēng)壓不變，但是風(fēng)量會上升。風(fēng)量加大故散熱效果增加，在設(shè)計(jì)中如果出現(xiàn)散熱功率太小則可以考慮增加風(fēng)扇來解決。 </p> <p> 2、串聯(lián)風(fēng)扇:串聯(lián)風(fēng)扇的結(jié)果是風(fēng)壓增加，但是風(fēng)量不變。此方式是不能解決散熱問題，一般是用在近風(fēng)的阻力太大時采用，紹興可調(diào)式風(fēng)扇，紹興可調(diào)式風(fēng)扇，保證風(fēng)量。 </p> <p> 【主要事項(xiàng)】 </p> <p> 使用過程中為了降低低噪音必須注意以下幾點(diǎn): </p> <p> 系統(tǒng)阻抗:空氣流動阻力會引起空氣的流動噪音產(chǎn)生，紹興可調(diào)式風(fēng)扇。 </p> <p> 氣流的紊流:由于流道的設(shè)計(jì)不良造成空氣的紊流會有高頻噪音出現(xiàn)，如果流道不改善很難有質(zhì)的提高。 </p> <p> <span style="display:none;"></span> </p> <p> <br /> 風(fēng)扇的在進(jìn)行挑選時有什么技巧嗎？紹興可調(diào)式風(fēng)扇</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="紹興可調(diào)式風(fēng)扇,風(fēng)扇" src="https://tyunfile.71360.com/UploadFile/18867638280/637273869887900390/8765554.png"></div><p> 對于散熱風(fēng)扇的關(guān)注，除了散熱效果外，大家也還會關(guān)注散熱風(fēng)扇的工作噪音。 </p> <p> 由于風(fēng)扇噪音是風(fēng)扇工作時產(chǎn)生雜音的大小，受多個因素影響。在對散熱風(fēng)扇噪聲測量時要在噪聲小于17dB的消音室中進(jìn)行，切具有距離風(fēng)扇一米，并按散熱風(fēng)扇轉(zhuǎn)軸的方向?qū)?zhǔn)風(fēng)扇的進(jìn)氣口，采取A加權(quán)的方式進(jìn)行測量。另外，散熱風(fēng)扇噪聲的頻譜特性也很重要，所以需要使用頻譜儀將風(fēng)扇的噪聲頻率分布情況記錄下來，一般要求風(fēng)扇的噪聲盡可能的小，且不能出現(xiàn)異音。光亞風(fēng)扇哪家質(zhì)量好風(fēng)扇的種類有哪些呢？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="紹興可調(diào)式風(fēng)扇,風(fēng)扇"

風(fēng)扇轉(zhuǎn)運(yùn)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(jī)代替也可以。但是注意千萬不要使用食用油來替代，因?yàn)槠漕w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?yàn)槿~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(diǎn)，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(jìn)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> 風(fēng)扇基本構(gòu)造： </p> <p> 主要由四部分組成 </p> <p> 轉(zhuǎn)子:由磁鐵、扇葉及軸組成; </p> <p> 定子:由硅鋼片、線軸及軸承組成; </p> <p> 控制電路:由IC感應(yīng)磁鐵; </p> <p> S.極經(jīng)由電路控制其線圈導(dǎo)通而產(chǎn)生內(nèi)部激磁使轉(zhuǎn)子旋轉(zhuǎn)。 </p> <p> 工作原理 </p> <p> 電風(fēng)扇的主要部件是:交流電動機(jī)。其工作原理是:通電線圈在磁場中受力而轉(zhuǎn)動。能量的轉(zhuǎn)化形式是:電能主要轉(zhuǎn)化為機(jī)械能，同時由于線圈有電阻，所以不可避免的有一部分電能要轉(zhuǎn)化為熱能。 </p> <p> 電風(fēng)扇工作時(假設(shè)房間與外界沒有熱傳遞)室內(nèi)的溫度不僅沒有降低，反而會升高。讓我們一塊來分析一下溫度升高的原因:電風(fēng)扇工作時，由于有電流通過電風(fēng)扇的線圈，導(dǎo)線是有電阻的，所以會不可避免的產(chǎn)生熱量向外放熱，故溫度會升高。但人們?yōu)槭裁磿杏X到?jīng)鏊?因?yàn)槿梭w的體表有大量的汗液，當(dāng)電風(fēng)扇工作起來以后，室內(nèi)的空氣會流動起來，所以就能夠促進(jìn)汗液的急速蒸發(fā)，結(jié)合"蒸發(fā)需要吸收大量的熱量"，因此人們會感覺到?jīng)鏊?</p>

1.風(fēng)扇軸承的摩擦與振動:不但產(chǎn)生噪音,而且影響性能,縮短器件壽命,降低能源利用效率,是產(chǎn)品設(shè)計(jì)中盡量解決的關(guān)鍵技術(shù)問題。 </p> <p> 2.風(fēng)扇扇葉的振動:一般采用塑料制作的風(fēng)扇扇葉具有一定的韌性,可以承受一定程度的物理形變,同樣也會在推動空氣過程中因受力發(fā)生振動,但幅度一般較小。另一種較為嚴(yán)重的振動則是由于扇葉質(zhì)量分布不均,質(zhì)心與旋轉(zhuǎn)軸心存在偏心距所致。當(dāng)扇葉面積(質(zhì)量)或偏心距較大的情況下,可能會帶動風(fēng)扇甚至散熱器整體發(fā)生振動,進(jìn)而波及整個機(jī)箱。如果發(fā)生此類現(xiàn)象,則有可能是風(fēng)扇品質(zhì)與工作狀態(tài)。 </p> <p> 3.風(fēng)扇風(fēng)噪:流動的空氣之間互相沖擾,與周圍物體發(fā)生摩擦,葉片對氣流的分離作用,周期性送風(fēng)的脈動力等,都會產(chǎn)生噪音?？諝饬魉僭娇?湍流越多,往往風(fēng)噪也越大,而且會隨著風(fēng)速的提高呈加速度增大。普通的軸流風(fēng)扇會在扇葉與外框間的空隙處產(chǎn)生反激氣流,產(chǎn)生較大風(fēng)噪的同時,更會對風(fēng)量造成不利影響,也正因此出現(xiàn)了折緣、側(cè)進(jìn)風(fēng)等改良設(shè)計(jì)。

風(fēng)扇主軸直徑:由于電機(jī)與軸承的存在,軸流風(fēng)扇主軸所在的中心部分難免一定無氣流通過的盲區(qū),主軸直徑便決定著此盲區(qū)的大小。主軸直徑的大小則主要取決于風(fēng)扇電機(jī)的功率——大功率的電機(jī)需要更大的定子繞組線圈,必然占用更多的空間,在無法縱向擴(kuò)展(增加高度)的情況下,便只好橫向擴(kuò)展(增大面積)。 </p> <p> 風(fēng)扇葉片光滑度:這是一項(xiàng)非設(shè)計(jì)因素影響的指標(biāo),基本上取決于生產(chǎn)者的模具成形與后期處理工藝。在設(shè)計(jì)曲線之外,葉片上的不平整會在旋轉(zhuǎn)中產(chǎn)生紊流,增加摩擦,降低風(fēng)扇效率,折損風(fēng)扇性能,增大工作噪音。因此,應(yīng)對葉片表面的光滑度嚴(yán)格控制,如果所購產(chǎn)品處理不佳,則應(yīng)考率采用手工打磨等后續(xù)手段彌補(bǔ)。
