鈦翅(chi)片管(guan)相比不(bu)銹鋼(gang)翅(chi)片管(guan)和碳鋼(gang)翅(chi)片管(guan)來說在*內應(ying)用(yong)還不(bu)是那(nei)么廣泛。鈦翅(chi)片管(guan)*次被日新興(xing)業公司用(yong)于漁船用(yong)制(zhi)(zhi)(zhi)冷(leng)機(ji)的熱(re)(re)交(jiao)(jiao)換器(qi)(qi)是在2018年12月。鈦翅(chi)片管(guan)傳熱(re)(re)面積約為普通(tong)管(guan)的2-3倍。增(zeng)大(da)傳熱(re)(re)面積有(you)助于增(zeng)加熱(re)(re)交(jiao)(jiao)換器(qi)(qi)的熱(re)(re)交(jiao)(jiao)換(制(zhi)(zhi)(zhi)冷(leng))能力并節省空間，同時由于鈦具有(you)出色的耐蝕(shi)性，使(shi)其適用(yong)于使(shi)用(yong)腐蝕(shi)性制(zhi)(zhi)(zhi)冷(leng)劑(ji)(如海水和氨)的船用(yong)制(zhi)(zhi)(zhi)冷(leng)機(ji)熱(re)(re)交(jiao)(jiao)換器(qi)(qi)和空調(diao)設備。

　　鈦螺(luo)紋(wen)(wen)管(guan)(guan)(guan)(guan)(又稱(cheng)為(wei)鈦翅(chi)片(pian)管(guan)(guan)(guan)(guan))、翅(chi)片(pian)管(guan)(guan)(guan)(guan)(相(xiang)對地可稱(cheng)為(wei)高翅(chi)片(pian)管(guan)(guan)(guan)(guan))、螺(luo)旋槽(cao)紋(wen)(wen)管(guan)(guan)(guan)(guan)、橫槽(cao)紋(wen)(wen)管(guan)(guan)(guan)(guan)，螺(luo)旋扁(bian)管(guan)(guan)(guan)(guan)、縮放管(guan)(guan)(guan)(guan)及(ji)鋸齒形(xing)(xing)(或(huo)T形(xing)(xing))翅(chi)片(pian)管(guan)(guan)(guan)(guan)、波(bo)節管(guan)(guan)(guan)(guan)以及(ji)在螺(luo)紋(wen)(wen)管(guan)(guan)(guan)(guan)內設置內插物等。在換熱及(ji)海(hai)水淡化等工業應用效果明顯(xian)，性能優異。

　　1、鈦(tai)螺(luo)紋管(guan)結(jie)構特點

　　鈦螺(luo)紋(wen)管(guan)(guan)(guan)是鈦管(guan)(guan)(guan)軋(ya)制而(er)成的整體低(di)翅片(pian)管(guan)(guan)(guan)，螺(luo)紋(wen)換熱(re)管(guan)(guan)(guan)和光管(guan)(guan)(guan)換熱(re)管(guan)(guan)(guan)通過工藝計算可(ke)知，螺(luo)紋(wen)管(guan)(guan)(guan)的管(guan)(guan)(guan)外(wai)表面(mian)積較之(zhi)光管(guan)(guan)(guan)增加 1.5 倍(bei)～3倍(bei)，因而(er)強化(hua)了管(guan)(guan)(guan)外(wai)傳熱(re)。

　　2、鈦螺紋管傳熱性能

　　鈦螺紋管(guan)(guan)是由管(guan)(guan)子本身經整體軋制(zhi)而成的(de)，其(qi)螺紋狀的(de)低翅片與管(guan)(guan)子構(gou)成*體，無接觸熱(re)阻，強度高，耐熱(re)震(zhen)和機械振動，因而具有較好的(de)力學傳熱(re)和熱(re)膨脹(zhang)等性能(neng)。

　　3、鈦(tai)螺紋管應用(yong)

　　⑴螺紋(wen)管用(yong)(yong)(yong)來強化有(you)相(xiang)變液體的傳(chuan)熱，如(ru)在臥式冷凝(ning)器中可以(yi)用(yong)(yong)(yong)來冷凝(ning)氟利昂及(ji)輕質(zhi)油等有(you)機蒸氣，其優點是：①節(jie)(jie)(jie)省設備費用(yong)(yong)(yong)。當管內冷卻水流速v>1m/ s時(shi)，冷凝(ning)傳(chuan)熱系數比光管提高 1 倍以(yi)上。按(an)公稱直徑計算，其傳(chuan)熱面(mian)積只需光管的 1/ 2～1/2.5。②清(qing)洗方便，節(jie)(jie)(jie)約操作(zuo)費用(yong)(yong)(yong)，做到(dao)節(jie)(jie)(jie)能(neng)增效。

　　⑵海(hai)(hai)水是近(jin)海(hai)(hai)的(de)石油化(hua)工裝置取(qu)之(zhi)不竭的(de)冷(leng)卻水源。在選(xuan)擇換熱器材質時,鈦(tai)制管材耐腐(fu)性能(neng)(neng)明顯(xian)。在海(hai)(hai)水作(zuo)用下(xia),銅鎳合金(jin)管或碳鋼管會逐(zhu)步(bu)被腐(fu)蝕,鈦(tai)管則具有高強度、優良耐腐(fu)蝕性和(he)chi久的(de)耐海(hai)(hai)水侵蝕的(de)du特性能(neng)(neng)。
