產品介紹

大(da)型風道(dao)加(jia)(jia)熱(re)器(qi)是主要對氣體流(liu)(liu)進行加(jia)(jia)熱(re)的(de)電(dian)加(jia)(jia)熱(re)設備。風道(dao)加(jia)(jia)熱(re)器(qi)的(de)發(fa)熱(re)元件(jian)為不(bu)銹鋼(gang)電(dian)加(jia)(jia)熱(re)管(guan)(guan)，加(jia)(jia)熱(re)器(qi)內(nei)腔設有多個折流(liu)(liu)板（導(dao)流(liu)(liu)板），引導(dao)氣體流(liu)(liu)向(xiang)，延長氣體在內(nei)腔的(de)滯留(liu)時間，從而使氣體充分加(jia)(jia)熱(re)，使氣體加(jia)(jia)熱(re)均勻，提高熱(re)交換(huan)效率。風道(dao)加(jia)(jia)熱(re)器(qi)的(de)加(jia)(jia)熱(re)元件(jian)不(bu)銹鋼(gang)加(jia)(jia)熱(re)管(guan)(guan)，是在無縫(feng)鋼(gang)管(guan)(guan)內(nei)裝入電(dian)熱(re)絲，空隙部分填滿(man)有良好導(dao)熱(re)性和絕緣性的(de)氧化鎂(mei)(mei)粉(fen)后縮管(guan)(guan)而成的(de)。當電(dian)流(liu)(liu)通(tong)過高溫電(dian)阻絲的(de)時候，產生(sheng)的(de)熱(re)通(tong)過結(jie)晶氧化鎂(mei)(mei)粉(fen)向(xiang)加(jia)(jia)熱(re)管(guan)(guan)表(biao)面(mian)擴散，再傳(chuan)遞到(dao)被加(jia)(jia)熱(re)氣體中去，以達(da)到(dao)加(jia)(jia)熱(re)的(de)目(mu)的(de)。

產品結構

技(ji)術特(te)點

1、能使氣體(ti)加熱到很高(gao)的(de)的(de)溫(wen)度，可達(da)800℃，殼體(ti)溫(wen)度只有50℃左右。

2、風道(dao)加熱(re)器效率高。

3、升溫(wen)(wen)和降溫(wen)(wen)速率快，可達10℃/S，調節快而穩定。不會出現所控(kong)(kong)氣體溫(wen)(wen)度超(chao)前和滯后現象(xiang)而使溫(wen)(wen)度控(kong)(kong)制(zhi)漂移不定，很適合(he)自動控(kong)(kong)制(zhi)。

4、機械性(xing)能(neng)好：因為(wei)它的發(fa)熱(re)體為(wei)特制合金材料，所以在高壓氣體流的沖(chong)擊下(xia)，它比任何發(fa)熱(re)體的機械性(xing)能(neng)和(he)強(qiang)度都好，這對(dui)于需要長時間連續不斷對(dui)氣體加溫(wen)的系統和(he)附件試驗更具有優越性(xing)。

5、在不違反使用規程(cheng)時，經久耐用，使用壽命長(chang)達幾十年。

6、氣體潔凈，體積小。
