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，舟山橫流風(fēng)扇。此方式是不能解決散熱問題，舟山橫流風(fēng)扇，一般是用在近風(fēng)的阻力太大時(shí)采用，舟山橫流風(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(dòng)阻力會引起空氣的流動(dòng)噪音產(chǎn)生。 </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

alt="舟山橫流風(fēng)扇,風(fēng)扇" src="https://tyunfile.71360.com/UploadFile/18867638280/637273868800322265/2992686.png"></div><p> 風(fēng)扇冷散熱器的工作噪音主要有三個(gè)來源:軸承的摩擦與振動(dòng)、扇葉的振動(dòng)、風(fēng)噪。 </p> <p> 1.風(fēng)扇軸承的摩擦與振動(dòng):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(dòng):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(dòng)空氣過程中因受力發(fā)生振動(dòng),但幅度一般較小。另一種較為嚴(yán)重的振動(dòng)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(dòng)風(fēng)扇甚至散熱器整體發(fā)生振動(dòng),進(jìn)而波及整個(gè)機(jī)箱。如果發(fā)生此類現(xiàn)象,則應(yīng)懷疑風(fēng)扇品質(zhì)與工作狀態(tài)。 </p> <p> 3.風(fēng)扇風(fēng)噪:流動(dòng)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(dòng)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(shí),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)速是風(fēng)扇重要的性能指標(biāo)之一,與重要的兩項(xiàng)性能指標(biāo)之一風(fēng)量關(guān)系密切。 </p> <p> 風(fēng)速即風(fēng)扇出風(fēng)口或進(jìn)風(fēng)口的空氣流動(dòng)速度,單位一般為m/s;*是某一位置的速度數(shù)值,不能完全體現(xiàn)風(fēng)扇的性能。風(fēng)速在不同位置數(shù)值可能有較大差異,且平均值難以計(jì)算,一般不用來表示風(fēng)扇的性能。 </p> <p> 風(fēng)速的高低主要取決于扇葉的形狀、面積、高度以及轉(zhuǎn)速。扇葉形狀設(shè)計(jì)、面積、高度的影響較為復(fù)雜;風(fēng)扇轉(zhuǎn)速越快,風(fēng)速越快,則是顯而易見的常識。 </p> <p> <br /> </p><p> 衡量一款風(fēng)扇的品質(zhì),重要的兩個(gè)方面為性能與壽命,其次便是越來越受到關(guān)注的工作噪音;此外,關(guān)系到能否正常使用,還必須注意風(fēng)扇的規(guī)格與功率。 </p> <p> 與底面尺寸息息相關(guān)的數(shù)據(jù)為過風(fēng)面積(風(fēng)扇底面積減去外框與電機(jī)占據(jù)部分所占面積的結(jié)果),進(jìn)一步則影響到風(fēng)扇的重要性能指標(biāo)“風(fēng)量”。擁有更大的底面尺寸,一般就可以獲得更大的過風(fēng)面積,在風(fēng)速相當(dāng)?shù)那闆r下,將獲得更大的風(fēng)量;反過來考慮,就可以降低風(fēng)速卻不減少風(fēng)量,采用“大口徑”風(fēng)扇也是目前風(fēng)冷散熱器發(fā)展的大趨勢之一。 </p> <p> 增加風(fēng)扇的高度有利于增大風(fēng)扇功率、加大扇葉面積,都可以增強(qiáng)風(fēng)扇的性能;有些風(fēng)扇也會利用增加的高度在外框上添加導(dǎo)流片或改變扇葉旋轉(zhuǎn)面方向(即非軸流風(fēng)扇)等。 </p> <p> <br /> 風(fēng)扇的電源線不能接觸有害氣體。</p><div
