日本三菱公司開(kāi)發(fā)的這種幾乎沒(méi)有噪聲的電風(fēng)扇，裝有特制的鳥(niǎo)翅狀葉片，可產(chǎn)生一股渦動(dòng)氣流，且采用直流電機(jī)，不加防護(hù)罩，很適合有微機(jī)、文字處理機(jī)、復(fù)印機(jī)的場(chǎng)所使用。 </p> <p> 燈頭電風(fēng)扇 </p> <p> 美國(guó)發(fā)明的這種可安裝在燈泡燈頭上的電風(fēng)扇，小巧玲瓏，只要有安裝燈泡的燈頭就可使用，不*安裝簡(jiǎn)便，而且能節(jié)省能源。 </p> <p> 四季電風(fēng)扇 </p> <p> 德國(guó)生產(chǎn)出的這種四季都能用的電風(fēng)扇，配有遠(yuǎn)紅外線加熱器和負(fù)離子發(fā)生器，能夏季送涼風(fēng)、冬季送熱風(fēng)，一年四季送負(fù)離子風(fēng)，具有送涼取暖，凈化空氣，防病保健功效。 </p> <p> 火柴盒電風(fēng)扇 </p> <p> 法國(guó)開(kāi)發(fā)出的這種微型風(fēng)扇，體積只有火柴盒大小，厚度為14毫米，長(zhǎng)度為62毫米，重量*為45克，使用12至24伏的直流電，兩瓦功率，連續(xù)使用壽命可達(dá)1萬(wàn)小時(shí)。 </p><p> 風(fēng)扇轉(zhuǎn)速 </p> <p> 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)滿足需求。一些廠商特意設(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)。風(fēng)扇用久以后，扇葉的下面很容易沾上很多灰塵。</p><div
