北京供應半容積式換熱器管殼式換熱器(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，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。北京半容積式換熱器廠家進行換熱的冷熱兩種(zhong)流(liu)體，一種(zhong)在(zai)管(guan)內流(liu)動(dong)，稱為管(guan)程流(liu)體；另(ling)一種(zhong)在(zai)管(guan)外流(liu)動(dong)，稱為殼(ke)程流(liu)體。
