DXW/PZ/J 型自限式(shi)電(dian)熱帶

自限式電熱帶

型號含義：

例(li)： DXW-PZ/J表示：絕緣(yuan)材料為(wei)PTC復(fu)合性，額(e)定工作電壓為(wei)220V、20℃時每(mei)米輸出功率20W的自限工電熱帶。

工作原(yuan)理(li)：兩根(gen)銅絞線(xian)為電(dian)(dian)(dian)(dian)源母(mu)線(xian)，在母(mu)線(xian)周(zhou)圍擠(ji)塑一層有正溫(wen)(wen)(wen)系數特(te)性(xing)的(de)自限(xian)發熱(re)(re)芯料，當(dang)接(jie)(jie)通(tong)(tong)(tong)電(dian)(dian)(dian)(dian)源后，電(dian)(dian)(dian)(dian)源橫向通(tong)(tong)(tong)過芯料，形成了(le)(le)一個連續的(de)并聯加(jia)熱(re)(re)體(ti)。本(ben)電(dian)(dian)(dian)(dian)熱(re)(re)帶發熱(re)(re)芯料采(cai)用(yong)經特(te)種(zhong)工藝處理(li)的(de)溫(wen)(wen)(wen)度記憶導(dao)(dao)電(dian)(dian)(dian)(dian)分(fen)(fen)子。當(dang)電(dian)(dian)(dian)(dian)流(liu)(liu)通(tong)(tong)(tong)過網(wang)絡導(dao)(dao)電(dian)(dian)(dian)(dian)分(fen)(fen)子時(shi)，產生(sheng)熱(re)(re)量(liang)(liang)。在冷態時(shi)，電(dian)(dian)(dian)(dian)流(liu)(liu)易于通(tong)(tong)(tong)過，產生(sheng)大量(liang)(liang)熱(re)(re)能(neng)。隨著(zhu)溫(wen)(wen)(wen)度升高(gao)，基體(ti)膨(peng)脹，導(dao)(dao)電(dian)(dian)(dian)(dian)分(fen)(fen)子減(jian)(jian)低了(le)(le)網(wang)絡密度，切斷(duan)了(le)(le)大部分(fen)(fen)通(tong)(tong)(tong)路，電(dian)(dian)(dian)(dian)流(liu)(liu)減(jian)(jian)少，發熱(re)(re)量(liang)(liang)隨之(zhi)(zhi)減(jian)(jian)少，由此，達(da)到(dao)自動(dong)控制溫(wen)(wen)(wen)度目的(de)，使加(jia)熱(re)(re)基本(ben)超于熱(re)(re)平衡。當(dang)溫(wen)(wen)(wen)度下降，溫(wen)(wen)(wen)度記憶導(dao)(dao)電(dian)(dian)(dian)(dian)分(fen)(fen)子再(zai)(zai)次(ci)收縮，結(jie)果，原(yuan)先切斷(duan)的(de)電(dian)(dian)(dian)(dian)路有恢復接(jie)(jie)通(tong)(tong)(tong)，電(dian)(dian)(dian)(dian)流(liu)(liu)再(zai)(zai)次(ci)增大，熱(re)(re)量(liang)(liang)輸出增加(jia)。這種(zhong)特(te)性(xing)稱之(zhi)(zhi)謂：“溫(wen)(wen)(wen)度自限(xian)式特(te)性(xing)”，“自限(xian)式電(dian)(dian)(dian)(dian)熱(re)(re)帶”名稱由此而產生(sheng)。
