流程和流道的選擇流程指板式換熱器內(nèi)一種介質(zhì)同前列動方向的一組并聯(lián)流道，而流道指板式換熱器內(nèi)，相鄰兩板片組成的介質(zhì)流動通道。一般情況下，將若干個流道按并聯(lián)或串聯(lián)的方式連接起來，以形成冷、熱介質(zhì)通道的不同組合。流程組合形式應(yīng)根據(jù)換熱和流體阻力計算，在滿足工藝條件要求下確定。盡量使冷、熱水流道內(nèi)的對流換熱系數(shù)相等或接近，從而得到比較好的傳熱效果。因為在傳熱表面兩側(cè)對流換熱系數(shù)相等或接近時傳熱系數(shù)獲得較大值。雖然板式換熱器各板間流速不等，但在換熱和流體阻力計算時，仍以平均流速進行計算。由于“U”形單流程的接管都固定在壓緊板上，拆裝方便。壓降校核在板式換熱器的設(shè)計選型時，一般對壓降有一定的要求，所以應(yīng)對其進行校核。如果校核壓降超過允許壓降，需重新進行設(shè)計選型計算，直到滿足工藝要求為止。計算方法關(guān)于傳熱系數(shù)和壓降的計算，由各個廠家產(chǎn)品的性能曲線計算得到。性能曲線（準則關(guān)聯(lián)式）一般來自于產(chǎn)品的性能測試。對于缺少性能測試的板型，也可通過參考尺寸法，根據(jù)板型的特性幾何尺寸獲得板型的準則關(guān)聯(lián)式，國際上的一些通用軟件均采用這種方法。選型軟件關(guān)于板式換熱器的選型軟件。</p><div
