導熱油電加熱設備介(jie)紹電(dian)(dian)(dian)加熱(re)(re)(re)(re)(re)是將電(dian)(dian)(dian)能轉(zhuan)換為熱(re)(re)(re)(re)(re)能的(de)(de)(de)過程。自從(cong)發(fa)現電(dian)(dian)(dian)源通過導線可以發(fa)生(sheng)熱(re)(re)(re)(re)(re)效應之后，世(shi)界上就許多(duo)發(fa)明家從(cong)事(shi)于(yu)(yu)各種電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)電(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)研究與(yu)制造(zao)。電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)的(de)(de)(de)發(fa)展及普及應用(yong)也(ye)與(yu)其(qi)它(ta)行(xing)業一(yi)樣，遵循著(zhu)這樣一(yi)個規律：從(cong)先進電(dian)(dian)(dian)加熱(re)(re)(re)(re)(re)器(qi)(qi)的(de)(de)(de)國家逐步推廣到(dao)世(shi)界各國；從(cong)城市逐步發(fa)展到(dao)農村；由(you)(you)集體(ti)使(shi)用(yong)發(fa)展到(dao)家庭、再到(dao)個人；產(chan)品由(you)(you)低(di)檔(dang)發(fa)展到(dao)高檔(dang)。十九世(shi)紀處于(yu)(yu)萌芽階段的(de)(de)(de)電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)電(dian)(dian)(dian)器(qi)(qi)大都是拙(zhuo)劣(lie)的(de)(de)(de)，出現早是用(yong)于(yu)(yu)生(sheng)活的(de)(de)(de)電(dian)(dian)(dian)熱(re)(re)(re)(re)(re)電(dian)(dian)(dian)器(qi)(qi)，1893年(nian)電(dian)(dian)(dian)慰斗的(de)(de)(de)雛型在(zai)美國出現并使(shi)用(yong)，接著(zhu)到(dao)1909年(nian)出現電(dian)(dian)(dian)灶(zao)的(de)(de)(de)使(shi)用(yong)，那是在(zai)爐(lu)灶(zao)中放置電(dian)(dian)(dian)加熱(re)(re)(re)(re)(re)器(qi)(qi)，也(ye)就是說(shuo)加熱(re)(re)(re)(re)(re)從(cong)柴禾轉(zhuan)移到(dao)電(dian)(dian)(dian)氣，即從(cong)電(dian)(dian)(dian)能轉(zhuan)變為熱(re)(re)(re)(re)(re)能。
