防爆電加熱器概述
防爆電加(jia)(jia)熱(re)器(qi)是一種(zhong)國(guo)際流行的(de)高品質(zhi)(zhi)(zhi)長壽命電加(jia)(jia)熱(re)設備。用(yong)于(yu)對流動(dong)的(de)液(ye)態(tai)、氣態(tai)介(jie)質(zhi)(zhi)(zhi)的(de)升溫(wen)、保溫(wen)、加(jia)(jia)熱(re)。當加(jia)(jia)熱(re)介(jie)質(zhi)(zhi)(zhi)在壓力作用(yong)下通過電加(jia)(jia)熱(re)器(qi)加(jia)(jia)熱(re)腔,采用(yong)流體熱(re)力學(xue)原理均勻地(di)帶走電熱(re)元件工作中所(suo)產生的(de)巨大(da)熱(re)量,使被(bei)加(jia)(jia)熱(re)介(jie)質(zhi)(zhi)(zhi)溫(wen)度達到用(yong)戶工藝要求。
