電(dian)(dian)伴(ban)(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)和電(dian)(dian)加(jia)熱(re)(re)(re)(re)的區(qu)別是什么呢？電(dian)(dian)伴(ban)(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)是利用(yong)絕緣電(dian)(dian)阻(zu)導電(dian)(dian)塑(su)料或者(zhe)是電(dian)(dian)阻(zu)發熱(re)(re)(re)(re)絲(si)，其主(zhu)要(yao)代表(biao)有(you)自限溫(wen)(wen)(wen)伴(ban)(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)帶和恒(heng)功率(lv)伴(ban)(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)帶，是在伴(ban)(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)領域使用(yong)頻繁的兩種產(chan)品(pin)。它們的功率(lv)都不太(tai)大，初因其主(zhu)要(yao)的作用(yong)是為(wei)了滿(man)足工藝(yi)設(she)計(ji)的要(yao)求(qiu)來給(gei)管(guan)道伴(ban)(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)，慢慢地延伸到更多設(she)備(bei)方面的伴(ban)(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)。選(xuan)好(hao)溫(wen)(wen)(wen)度型號合適的自限溫(wen)(wen)(wen)產(chan)品(pin)以(yi)后(hou)，可以(yi)不需要(yao)配備(bei)溫(wen)(wen)(wen)控(kong)器，而恒(heng)功率(lv)是通過電(dian)(dian)阻(zu)絲(si)來進行發熱(re)(re)(re)(re)，因而使用(yong)溫(wen)(wen)(wen)控(kong)器來限制溫(wen)(wen)(wen)度，一般后(hou)者(zhe)也可以(yi)被叫(jiao)做高(gao)溫(wen)(wen)(wen)電(dian)(dian)伴(ban)(ban)(ban)(ban)(ban)熱(re)(re)(re)(re)產(chan)品(pin)，其高(gao)維(wei)持溫(wen)(wen)(wen)度可達到150度左(zuo)右，高(gao)表(biao)面耐(nai)溫(wen)(wen)(wen)為(wei)205度。

電(dian)加(jia)熱(re)(re)(re)，從(cong)字面上理(li)解也(ye)是(shi)一(yi)種利用電(dian)能轉化為熱(re)(re)(re)能的(de)(de)(de)(de)設備，其(qi)(qi)工(gong)作原(yuan)理(li)是(shi)高(gao)頻的(de)(de)(de)(de)高(gao)頻大電(dian)流(liu)(liu)流(liu)(liu)向被繞制成環狀(zhuang)或其(qi)(qi)它形狀(zhuang)的(de)(de)(de)(de)加(jia)熱(re)(re)(re)線(xian)圈(quan)，在線(xian)圈(quan)內放入金屬等被加(jia)熱(re)(re)(re)的(de)(de)(de)(de)物體，被磁束(shu)貫(guan)穿產生渦電(dian)流(liu)(liu)從(cong)而使(shi)得物體溫度(du)迅(xun)速(su)上升。由此(ci)可見，這(zhe)是(shi)一(yi)種為物體加(jia)熱(re)(re)(re)的(de)(de)(de)(de)設備，不同(tong)于電(dian)伴熱(re)(re)(re)的(de)(de)(de)(de)就(jiu)(jiu)是(shi)其(qi)(qi)功(gong)率一(yi)定很大才(cai)能瞬間將(jiang)物體加(jia)熱(re)(re)(re)到(dao)(dao)所需的(de)(de)(de)(de)要(yao)求。常用的(de)(de)(de)(de)電(dian)加(jia)熱(re)(re)(re)，小(xiao)編(bian)很快(kuai)就(jiu)(jiu)想到(dao)(dao)了“熱(re)(re)(re)得快(kuai)”，一(yi)般電(dian)加(jia)熱(re)(re)(re)器(qi)使(shi)用方式也(ye)如此(ci)，將(jiang)其(qi)(qi)插入被加(jia)熱(re)(re)(re)的(de)(de)(de)(de)物體中(zhong)，在短的(de)(de)(de)(de)時間迅(xun)速(su)加(jia)熱(re)(re)(re)到(dao)(dao)所需的(de)(de)(de)(de)溫度(du)。
