管殼式換熱器(shell and tube heat exchanger)又稱列管式換熱器。管殼式換熱器是以封閉在殼體中管束的壁面作為傳熱面的間壁式換熱器。這種換熱器結構較簡單，操作可靠，熱交換器廠家可用各種結構材料（主要是金屬材料）制造，能在高溫、高壓下使用，是目前應用廣的類型。管殼式換熱器是怎樣運行的管殼式換熱器由殼體、傳熱管束、管板、折流板（擋板）和管箱等部件組成。殼體多為圓筒形，內部裝有管束，管束兩端固定在管板上。進行換熱的冷熱兩種流體，一種在管內流動，稱為管程流體；另一種在管外流動，稱為殼程流體。連云港熱交換器廠家為提高管(guan)外流體(ti)(ti)的(de)傳熱分系數，通常在殼體(ti)(ti)內安裝若干(gan)擋(dang)板。擋(dang)板可提高殼程流體(ti)(ti)速(su)度(du)，迫使流體(ti)(ti)按規定路程多次橫向通過管(guan)束(shu)，增強流體(ti)(ti)湍(tuan)流程度(du)。換熱管(guan)在管(guan)板上(shang)可按等邊三角形(xing)(xing)或正方(fang)形(xing)(xing)排(pai)(pai)列。等邊三角形(xing)(xing)排(pai)(pai)列較緊湊，管(guan)外流體(ti)(ti)湍(tuan)動程度(du)高，傳熱分系數大；正方(fang)形(xing)(xing)排(pai)(pai)列則管(guan)外清洗方(fang)便(bian)，適用于(yu)易結垢的(de)流體(ti)(ti)。
