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，半容積式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。江西半容積式熱交換器廠家為提(ti)高管(guan)(guan)(guan)外(wai)流(liu)(liu)(liu)體的傳熱分(fen)系數，通(tong)常在(zai)殼(ke)體內安裝若干擋板。擋板可(ke)提(ti)高殼(ke)程(cheng)流(liu)(liu)(liu)體速度，迫使流(liu)(liu)(liu)體按(an)(an)規(gui)定路程(cheng)多次橫向通(tong)過管(guan)(guan)(guan)束，增強流(liu)(liu)(liu)體湍流(liu)(liu)(liu)程(cheng)度。換熱管(guan)(guan)(guan)在(zai)管(guan)(guan)(guan)板上可(ke)按(an)(an)等邊(bian)三角形或正(zheng)方形排列(lie)。等邊(bian)三角形排列(lie)較緊(jin)湊(cou)，管(guan)(guan)(guan)外(wai)流(liu)(liu)(liu)體湍動程(cheng)度高，傳熱分(fen)系數大；正(zheng)方形排列(lie)則管(guan)(guan)(guan)外(wai)清洗方便，適(shi)用(yong)于易結垢(gou)的流(liu)(liu)(liu)體。
