電源模塊被應(yīng)用在生活的方方面面，所一我們就要選擇好的電源模塊，盡管用機(jī)殼升溫來考量電源模塊的優(yōu)劣并不是精確，可是電源模塊就好像一個發(fā)熱原，對電控系統(tǒng)和其他元器件有挺大的危害。當(dāng)電源模塊機(jī)殼升溫超過125℃時，內(nèi)部升溫較好是把控在150℃內(nèi)，可是這一標(biāo)準(zhǔn)對現(xiàn)階段而言是有難度系數(shù)的。電源越熱時散發(fā)出去的熱量也就越多，能夠更強(qiáng)的推動排熱，降低升溫。機(jī)殼升溫是和商品內(nèi)部元器件升溫息息相關(guān)，決定著電源模塊的使用壽命和穩(wěn)定性。高溫會加快元器件脆化，把控升溫范疇，能夠增加使用期和降低常見故障的產(chǎn)生。電源模塊在不一樣的應(yīng)用場所和工作溫度，選用排熱的方法都是不同。當(dāng)在三四十度工作溫度下應(yīng)用，機(jī)殼升溫超過七八十度，這算作一切正常應(yīng)用，不在封閉式的室內(nèi)空間能夠選用自然散熱、加電扇、加散熱器等對策。電源模塊的操作溫度就是指在一切正常工作中那時候的升溫，升溫就是指從常溫下升高到操作溫度的差值。AC/DC變換是將交流變換為直流。</p><div
