</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(xiàng)參數(shù),尋找適合目標(biāo)工作要求的組合，紹興上海永大專(zhuān)配風(fēng)扇,便是進(jìn)行扇葉設(shè)計(jì)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，紹興上海永大專(zhuān)配風(fēng)扇,足以寫(xiě)出幾篇博士論文了，紹興上海永大專(zhuān)配風(fēng)扇,但本文只是淺要分析風(fēng)冷散熱器的相關(guān)技術(shù),實(shí)無(wú)此必要,筆者也尚無(wú)此能力。

風(fēng)扇冷散熱器的工作噪音主要有三個(gè)來(lái)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(wèn)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(huì)在推動(dòng)空氣過(guò)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(huì)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(lèi)現(xiàn)象,則應(yīng)懷疑風(fēng)扇品質(zhì)與工作狀態(tài)。

3.風(fēng)扇風(fēng)噪:流動(dòng)的空氣之間互相沖擾,與周?chē)矬w發(fā)生摩擦,葉片對(duì)氣流的分離作用,周期性送風(fēng)的脈動(dòng)力等,都會(huì)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(huì)隨著風(fēng)速的提高呈加速度增大。普通的軸流風(fēng)扇會(huì)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(huì)對(duì)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)。

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(lái)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>

</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(huì)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 /> </p><p> 散熱風(fēng)扇是不同行業(yè)設(shè)備的輔助工具，它的主要工作就是進(jìn)行散熱，為的就是保障設(shè)備在長(zhǎng)時(shí)間的工作下面，也不會(huì)因自身所產(chǎn)生的熱量而燒壞本身。所以對(duì)于大多數(shù)設(shè)備來(lái)說(shuō)，只要散熱風(fēng)扇出現(xiàn)故障，那么必然會(huì)影響到自己本身使用壽命的。 </p> <p> 當(dāng)你在選擇散熱風(fēng)扇的時(shí)候，需要選擇符合自己設(shè)備參數(shù)的散熱風(fēng)扇，如果遠(yuǎn)離設(shè)計(jì)值的話，那么往往會(huì)使機(jī)器機(jī)器在運(yùn)行中保持超轉(zhuǎn)速、超負(fù)荷運(yùn)行，或者低轉(zhuǎn)速、低負(fù)荷運(yùn)轉(zhuǎn)，不能達(dá)到風(fēng)扇的工作性能，容易出現(xiàn)故障，所以建議大家選購(gòu)的時(shí)候，根據(jù)符合設(shè)備參數(shù)來(lái)進(jìn)行選擇散熱風(fēng)扇哦！比較好使用橡膠來(lái)固定風(fēng)扇，而不是金屬螺絲，這樣可以避免振動(dòng)。</p><div
