冷(leng)(leng)凝(ning)器(qi)(qi)(qi)(qi),是(shi)將熱流體(ti)(ti)的部分熱量(liang)傳遞給冷(leng)(leng)流體(ti)(ti)的設備,又稱熱交換器(qi)(qi)(qi)(qi)。冷(leng)(leng)凝(ning)器(qi)(qi)(qi)(qi)在化(hua)工(gong)(gong)、石油、動力(li)、食(shi)品及其它許(xu)多工(gong)(gong)業生(sheng)產(chan)中占有重要地位,其在化(hua)工(gong)(gong)生(sheng)產(chan)中冷(leng)(leng)凝(ning)器(qi)(qi)(qi)(qi)可作(zuo)為加(jia)熱器(qi)(qi)(qi)(qi)、冷(leng)(leng)凝(ning)器(qi)(qi)(qi)(qi)、蒸(zheng)發器(qi)(qi)(qi)(qi)和再沸器(qi)(qi)(qi)(qi)等,應(ying)用廣泛(fan)。

冷凝器是一種(zhong)(zhong)在(zai)不(bu)同溫度(du)(du)的(de)(de)(de)兩種(zhong)(zhong)或兩種(zhong)(zhong)體間實現物(wu)料(liao)之間熱(re)量傳遞的(de)(de)(de)節能設備(bei),是使熱(re)量由溫度(du)(du)較高的(de)(de)(de)流體傳遞給溫度(du)(du)較低(di)的(de)(de)(de)流體,使流體溫度(du)(du)達到流程規定的(de)(de)(de)指標,以滿足工(gong)藝條(tiao)件(jian)的(de)(de)(de)需要(yao),同時也是提高能源(yuan)利用率的(de)(de)(de)主要(yao)設備(bei)之一。冷凝器行(xing)業涉及暖通、壓力容器、中水處(chu)理設備(bei),化(hua)工(gong),石油(you)等近30多種(zhong)(zhong)產業,相(xiang)互形成產業鏈條(tiao)。
