風(fēng)扇轉(zhuǎn)速是指風(fēng)扇扇葉每分鐘旋轉(zhuǎn)的次數(shù)，單位是rpm。風(fēng)扇轉(zhuǎn)速由電機(jī)內(nèi)線(xiàn)圈的匝數(shù)、工作電壓、風(fēng)扇扇葉的數(shù)量、傾角、高度、直徑和軸承系統(tǒng)共同決定。轉(zhuǎn)速和風(fēng)扇質(zhì)量沒(méi)有必然的聯(lián)系。風(fēng)扇的轉(zhuǎn)速可以通過(guò)內(nèi)部的轉(zhuǎn)速信號(hào)進(jìn)行測(cè)量，也可以通過(guò)外部進(jìn)行測(cè)量。 </p> <p> 隨著應(yīng)用情況與環(huán)境溫度的變化，有時(shí)需要不同轉(zhuǎn)速風(fēng)扇來(lái)滿(mǎn)足需求。一些廠(chǎng)商特意設(shè)計(jì)出可調(diào)節(jié)風(fēng)扇轉(zhuǎn)速的散熱風(fēng)扇，分手動(dòng)和自動(dòng)兩種。手動(dòng)的主要是讓用戶(hù)可以在冬天使用低轉(zhuǎn)速獲得低噪音，夏天時(shí)使用高轉(zhuǎn)速獲得好的散熱效果。自動(dòng)類(lèi)調(diào)溫散熱器一般帶有一個(gè)溫控感應(yīng)器，能夠根據(jù)當(dāng)前的工作溫度自動(dòng)控制風(fēng)扇的轉(zhuǎn)速，溫度高則提高轉(zhuǎn)速，溫度低則降低轉(zhuǎn)速，以達(dá)到一個(gè)動(dòng)態(tài)的平衡，從而讓風(fēng)噪與散熱效果保持一個(gè)比較好的結(jié)合點(diǎn)。麗水電梯風(fēng)扇風(fēng)扇清理時(shí)不能用汽油或強(qiáng)堿液擦拭。</p><div

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(huì)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(lái)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(wèn)題，一般是用在近風(fēng)的阻力太大時(shí)采用，保證風(fēng)量。 </p> <p> 【主要事項(xiàng)】 </p> <p> 使用過(guò)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(huì)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(huì)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 /> </p><p> 對(duì)于散熱風(fēng)扇的關(guān)注，除了散熱效果外，大家也還會(huì)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(shí)產(chǎn)生雜音的大小，受多個(gè)因素影響。在對(duì)散熱風(fēng)扇噪聲測(cè)量時(shí)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(cè)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(lái)，一般要求風(fēng)扇的噪聲盡可能的小，且不能出現(xiàn)異音。振動(dòng)會(huì)造成風(fēng)扇的噪音上升。</p><div

噪音小:電風(fēng)扇制造噪音的主要部件是電機(jī)，在挑選電風(fēng)扇時(shí)一定要聽(tīng)一聽(tīng)電機(jī)運(yùn)轉(zhuǎn)時(shí)有無(wú)噪音，看它在運(yùn)轉(zhuǎn)時(shí)是否抖動(dòng)，是否平穩(wěn);好的電機(jī)讓你在安靜的環(huán)境中，只聽(tīng)到風(fēng)的""細(xì)語(yǔ)""，超靜音送風(fēng)的才是好風(fēng)扇。 </p> <p> 無(wú)臭氣:臭氣是電風(fēng)扇銅上的絕緣漆涂料在運(yùn)轉(zhuǎn)時(shí)產(chǎn)生的氣味，在選購(gòu)電風(fēng)扇時(shí)就得聞一聞，看這種漆是否環(huán)保，是否通過(guò)質(zhì)量檢測(cè)，讓你在清新的空氣中領(lǐng)略風(fēng)的涼爽。 </p> <p> 電氣安全:對(duì)電風(fēng)扇的安全要求，國(guó)家標(biāo)準(zhǔn)中規(guī)定得很詳細(xì)，消費(fèi)者也可以進(jìn)行簡(jiǎn)單的試驗(yàn)。合格的風(fēng)扇，一般大人的手指都不能通過(guò)網(wǎng)罩而觸及扇葉前緣，有小孩的家庭更應(yīng)選擇網(wǎng)罩密的電風(fēng)扇。風(fēng)扇用久以后，扇葉的下面很容易沾上很多灰塵。橫流風(fēng)扇</p><p
