除了散熱效果之外，風(fēng)扇的工作噪音也是人們普遍關(guān)注的問題。風(fēng)扇噪音是風(fēng)扇工作時(shí)產(chǎn)生雜音的大小，受多方面因素影響，單位為分貝(dB)。測量風(fēng)扇的噪聲時(shí)需要在噪聲小于17dB的消音室中進(jìn)行，距離風(fēng)扇一米，并沿風(fēng)扇轉(zhuǎn)軸的方向?qū)?zhǔn)風(fēng)扇的進(jìn)氣口，采用A加權(quán)的方式進(jìn)行測量。風(fēng)扇噪聲的頻譜特性也很重要，因此還需要用頻譜儀記錄風(fēng)扇的噪聲頻率分布情況，一般要求風(fēng)扇的噪聲要盡量的小，而且不能存在異音。 </p> <p> 風(fēng)扇噪音與摩擦力、空氣流動(dòng)有關(guān)。風(fēng)扇轉(zhuǎn)速越高、風(fēng)量越大，造成的噪音也會(huì)越大，另外風(fēng)扇自身的震動(dòng)也是不可忽視的因素。當(dāng)然***的風(fēng)扇的自身震動(dòng)會(huì)很小，但前面兩個(gè)者卻是難以克服的。要解決這個(gè)問題，我們可以嘗試使用尺寸較大的風(fēng)扇。應(yīng)在在風(fēng)量相同的情況下，大風(fēng)扇在較低轉(zhuǎn)速時(shí)的工作噪聲要小于小風(fēng)扇在高轉(zhuǎn)速時(shí)的工作噪聲。另外一個(gè)我們?nèi)菀缀雎缘囊蛩厥秋L(fēng)扇的軸承。由于風(fēng)扇高速轉(zhuǎn)動(dòng)時(shí)轉(zhuǎn)軸和軸承之間要摩擦碰撞，所以也是風(fēng)扇噪聲的一個(gè)主要來源。

一些人在購買散熱風(fēng)扇的時(shí)候，常常以為風(fēng)量大，散熱風(fēng)扇的散熱效果就更好！其實(shí)并非是這樣的，選擇質(zhì)量好的散熱風(fēng)扇，購買之后要對(duì)風(fēng)扇的轉(zhuǎn)速進(jìn)行相應(yīng)的調(diào)試。散熱風(fēng)扇進(jìn)行運(yùn)轉(zhuǎn)的時(shí)候，它不會(huì)產(chǎn)生噪音，減少能量的一些消耗。在大多數(shù)的設(shè)計(jì)要求中，在風(fēng)扇提速運(yùn)轉(zhuǎn)數(shù)小時(shí)后空氣溫度通常比較大的設(shè)計(jì)溫值更低，所以針對(duì)于這些問題，減少對(duì)一些設(shè)備的損耗！ </p> <p> 在大多數(shù)的設(shè)計(jì)要求中，在風(fēng)扇提速運(yùn)轉(zhuǎn)數(shù)小時(shí)后空氣溫度通常比較大的設(shè)計(jì)溫值更低，所以在通常的情況之下，低速運(yùn)轉(zhuǎn)的散熱風(fēng)扇能足夠地完成它的工作。 </p></p><br /><p>文章來源地址:
