　　如今我們(men)(men)在很多地方都需(xu)要使用到一種叫做管(guan)殼(ke)式(shi)(shi)(shi)(shi)換熱(re)器的產品，我們(men)(men)在選購管(guan)殼(ke)式(shi)(shi)(shi)(shi)換熱(re)器的時候，除了要注(zhu)意管(guan)殼(ke)式(shi)(shi)(shi)(shi)換熱(re)器的種類之外，還要注(zhu)意管(guan)殼(ke)式(shi)(shi)(shi)(shi)換熱(re)器結構。那么管(guan)殼(ke)式(shi)(shi)(shi)(shi)換熱(re)器結構主要有哪些呢？

　　螺旋折(zhe)流(liu)(liu)(liu)(liu)板(ban)螺旋折(zhe)流(liu)(liu)(liu)(liu)板(ban)是將(jiang)傳統的(de)垂直弓形板(ban)換成螺旋狀或近(jin)似螺旋狀的(de)折(zhe)流(liu)(liu)(liu)(liu)板(ban)，折(zhe)流(liu)(liu)(liu)(liu)板(ban)與管殼式(shi)換熱器殼體橫斷(duan)面有一個傾斜角(jiao)度，使得流(liu)(liu)(liu)(liu)體在(zai)殼程沿(yan)螺旋通道流(liu)(liu)(liu)(liu)動(dong)。按流(liu)(liu)(liu)(liu)道多(duo)少螺旋折(zhe)流(liu)(liu)(liu)(liu)可分為單頭(tou)或雙頭(tou)。

　　管(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱器(qi)結構(gou)圖—弓形(xing)折流(liu)板(ban)加(jia)平(ping)行分(fen)(fen)隔(ge)板(ban)管(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱器(qi)的(de)弓形(xing)折流(liu)板(ban)加(jia)平(ping)行分(fen)(fen)隔(ge)板(ban)在單弓折流(liu)隔(ge)板(ban)管(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱器(qi)的(de)兩折流(liu)隔(ge)板(ban)間(jian)平(ping)行插入了一塊或(huo)數塊平(ping)行流(liu)分(fen)(fen)隔(ge)板(ban)，可(ke)將(jiang)原通道(dao)改為(wei)多股平(ping)行通道(dao)，將(jiang)原單股流(liu)分(fen)(fen)為(wei)多股平(ping)行流(liu)。這樣(yang)，管(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱器(qi)就能有效控制板(ban)間(jian)回流(liu)死(si)區的(de)渦尺度，使板(ban)間(jian)流(liu)場得以均化及管(guan)(guan)間(jian)流(liu)阻得以減少。

　　管(guan)(guan)(guan)(guan)(guan)(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱(re)(re)器(qi)(qi)結(jie)(jie)構圖—整(zheng)(zheng)(zheng)圓形(xing)(xing)(xing)折(zhe)流(liu)(liu)(liu)(liu)板(ban)(ban)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱(re)(re)器(qi)(qi)的(de)(de)(de)(de)(de)整(zheng)(zheng)(zheng)圓形(xing)(xing)(xing)折(zhe)流(liu)(liu)(liu)(liu)板(ban)(ban)為(wei)了(le)盡可能(neng)地改變(bian)弓形(xing)(xing)(xing)折(zhe)流(liu)(liu)(liu)(liu)板(ban)(ban)支承(cheng)(cheng)的(de)(de)(de)(de)(de)橫向流(liu)(liu)(liu)(liu)動為(wei)平行(xing)于(yu)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)子的(de)(de)(de)(de)(de)縱向流(liu)(liu)(liu)(liu)動，滯留(liu)死區，提高流(liu)(liu)(liu)(liu)體(ti)在管(guan)(guan)(guan)(guan)(guan)(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱(re)(re)器(qi)(qi)殼(ke)程的(de)(de)(de)(de)(de)流(liu)(liu)(liu)(liu)速，在電站和石油化(hua)工(gong)中，出現了(le)整(zheng)(zheng)(zheng)圓形(xing)(xing)(xing)折(zhe)流(liu)(liu)(liu)(liu)板(ban)(ban)。管(guan)(guan)(guan)(guan)(guan)(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱(re)(re)器(qi)(qi)中出現的(de)(de)(de)(de)(de)整(zheng)(zheng)(zheng)圓形(xing)(xing)(xing)折(zhe)流(liu)(liu)(liu)(liu)板(ban)(ban)在板(ban)(ban)上鉆大圓孔(kong)(kong)，既讓管(guan)(guan)(guan)(guan)(guan)(guan)(guan)子通(tong)(tong)過(guo)，又有足夠的(de)(de)(de)(de)(de)間(jian)(jian)隙讓流(liu)(liu)(liu)(liu)體(ti)通(tong)(tong)過(guo)。管(guan)(guan)(guan)(guan)(guan)(guan)(guan)內外流(liu)(liu)(liu)(liu)體(ti)總體(ti)呈縱向流(liu)(liu)(liu)(liu)動，傳熱(re)(re)溫差(cha)推動力大，并(bing)且由于(yu)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)壁(bi)與孔(kong)(kong)板(ban)(ban)之(zhi)間(jian)(jian)的(de)(de)(de)(de)(de)圓環間(jian)(jian)隙通(tong)(tong)道對(dui)流(liu)(liu)(liu)(liu)體(ti)可產生射(she)流(liu)(liu)(liu)(liu)作用，使(shi)(shi)(shi)流(liu)(liu)(liu)(liu)體(ti)離開空口很(hen)快(kuai)就(jiu)形(xing)(xing)(xing)成湍(tuan)流(liu)(liu)(liu)(liu)，使(shi)(shi)(shi)壁(bi)面不易結(jie)(jie)垢，管(guan)(guan)(guan)(guan)(guan)(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱(re)(re)器(qi)(qi)的(de)(de)(de)(de)(de)殼(ke)程傳熱(re)(re)得到強化(hua)。但整(zheng)(zheng)(zheng)圓形(xing)(xing)(xing)折(zhe)流(liu)(liu)(liu)(liu)板(ban)(ban)增大了(le)換(huan)熱(re)(re)器(qi)(qi)殼(ke)體(ti)的(de)(de)(de)(de)(de)直徑，并(bing)且由于(yu)缺乏管(guan)(guan)(guan)(guan)(guan)(guan)(guan)子支承(cheng)(cheng)結(jie)(jie)構，這種管(guan)(guan)(guan)(guan)(guan)(guan)(guan)殼(ke)式(shi)(shi)換(huan)熱(re)(re)器(qi)(qi)的(de)(de)(de)(de)(de)管(guan)(guan)(guan)(guan)(guan)(guan)(guan)束(shu)抗振性(xing)能(neng)也很(hen)差(cha)。為(wei)改進大管(guan)(guan)(guan)(guan)(guan)(guan)(guan)孔(kong)(kong)整(zheng)(zheng)(zheng)圓形(xing)(xing)(xing)折(zhe)流(liu)(liu)(liu)(liu)板(ban)(ban)的(de)(de)(de)(de)(de)不足，在管(guan)(guan)(guan)(guan)(guan)(guan)(guan)孔(kong)(kong)之(zhi)間(jian)(jian)開小(xiao)孔(kong)(kong)，使(shi)(shi)(shi)傳熱(re)(re)介質由小(xiao)孔(kong)(kong)通(tong)(tong)過(guo)折(zhe)流(liu)(liu)(liu)(liu)板(ban)(ban)，這樣就(jiu)不用增大殼(ke)體(ti)的(de)(de)(de)(de)(de)直徑了(le)。
