換熱器是一種比較常見的工業設備，河北熱水機組能夠將熱流體設備的一部分熱量傳送到溫度相對較低的設備中。根據不同標準分類，可以將換熱器分成不同類別，不同類別的換熱器之間是存在差異的，有各自的優缺點，適用的場合也不盡相同。以下就是關于不同換熱器的優缺點的總結。不同換熱器的優點和缺點被加熱水通過罐體阻力損失小。結構簡單、管理方便，可承受水壓，噪音低。換熱面積大，換熱量高。熱水機組供(gong)水水壓、水溫(wen)穩(wen)定、安全、節水、用(yong)水舒適。使用(yong)壽命長。缺點(dian)：外(wai)形(xing)體積較大(da)、換(huan)(huan)熱(re)(re)(re)效(xiao)率(lv)相(xiang)對較低。殼(ke)程(cheng)清(qing)洗不方便。殼(ke)體與管子之(zhi)間無溫(wen)差補償元(yuan)件時會產生較大(da)的溫(wen)差應(ying)力， 即(ji)溫(wen)差較大(da)是需要采(cai)用(yong)膨脹節或(huo)波紋管等補償元(yuan)件減小溫(wen)差應(ying)力。板(ban)式(shi)換(huan)(huan)熱(re)(re)(re)器優點(dian)：傳熱(re)(re)(re)效(xiao)率(lv)高，對數溫(wen)差大(da)，重量(liang)輕、占地面(mian)積小，清(qing)洗方便，而且(qie)容易改變換(huan)(huan) 熱(re)(re)(re)面(mian)積或(huo)流(liu)程(cheng)組合，適用(yong)于(yu)多重介質換(huan)(huan)熱(re)(re)(re)。
