style="text-indent:25px">由于電源模塊越趨于小型化，功率密度相應(yīng)越來越高，大功率電源模塊有關(guān)熱設(shè)計方面的問題尤其突出。特別是對使用有電解電容的電源模塊，高溫會使電解電容的電解液加速消耗，有效減少電解電容的壽命。高溫會使元器件材料加速老化，例如使得變壓器漆包線的絕緣特性降低，內(nèi)蒙古大功率電源模塊費用，內(nèi)蒙古大功率電源模塊費用，導(dǎo)致絕緣耐壓不良甚至造成匝間短路。因此好的熱設(shè)計不僅可延長大功率電源模塊和其周圍元器件的使用壽命，還可使整個產(chǎn)品發(fā)熱均勻，減少故障的發(fā)生。所以除了基本性能參數(shù)測試，內(nèi)蒙古大功率電源模塊費用，多方面的高低溫測試，電應(yīng)力和熱應(yīng)力測試，保證足夠的降額設(shè)計要求，并通過長時間的老化測試，才可以判斷大功率電源模塊是否安全可靠。負(fù)載電流的大小是決定功率的關(guān)鍵。內(nèi)蒙古大功率電源模塊費用</p><div

style="text-indent:25px">散熱器翅片厚度的選擇也同樣會影響大功率電源模塊的散熱性能。在正常運行的情況下，由于導(dǎo)熱主要是沿著電源模塊的散熱器翅片縱向方向傳遞，因而翅片的厚度對于散熱器熱性能沒有太大的影響，翅片厚度的增加并沒有使熱源結(jié)溫降低很多，反而增加了散熱器的重量。為了保證散熱器翅片的硬度且易于加工，翅片硬度不能太薄，工程上一般會將散熱器翅片的厚度規(guī)定在≥1mm左右。散熱器翅片個數(shù)也同樣會影響到模塊電源的散熱性能。在模塊正常工作的前提下，隨著翅片數(shù)目的增多，熱源結(jié)溫會有所降低。但是超過某一數(shù)值之后，隨著翅片的增多，器件結(jié)溫不但沒有明顯變化反而散熱器的重量會明顯增加。同時，翅片數(shù)目增加有時還要考慮器件安裝的問題，有的器件安裝在散熱器兩翅片之間，如果翅片數(shù)太多，器件是不容易安裝在散熱器上的，因而工程師千萬不能盲目增加翅片的數(shù)目。</p><p
