一、換熱器按傳熱原理分類

1、表面式換熱器 表面式換熱器是溫度不同的兩種流體在被壁面分開的空間里流動,通過壁面的導熱和流體在壁表面對流,兩種流體之間進行換熱。表面式換熱器有管殼式、套管式、板式和其他型式的換熱器。

2、蓄熱式換熱器 蓄熱式換熱器通過固體物質構成的蓄熱體,把熱量從高溫流體傳遞給低溫流體,熱介質先通過加熱固體物質達到一定溫度后,通豪熱能把冷介質再通過固體物質被加熱,使之達到熱量傳遞的目的。蓄熱式換熱器有旋轉式、閥門切換式等。

3、流體連接間接式換熱器 流體連接間接式換熱器,是把兩個表面式換熱器由在其中循環的熱載體連接起來的換熱器,熱載體在高溫流體換熱器和低溫流體之間循環,通豪熱能在高溫流體接受熱量,在低溫流體換熱器把熱量釋放給低溫流體。

4、直接接觸式換熱器 直接接觸式換熱器是兩種流體直接接觸進行換熱的設備,例如,冷水塔、氣體冷凝器等。

二、換熱器按用途分類

1、加熱器 加熱器是把流體加熱到必要的溫度,但加熱流體沒有發生相的變化。

2、預熱器 預熱器預先加熱流體,為工序操作提供標準的工藝參數。

3、過熱器 過熱器用于把流體(工藝氣或蒸汽)加熱到過熱狀態。

4、蒸發器 蒸發器用于加熱流體,達到沸點以上溫度,使其流體蒸發,一般有相的變化。

三、按換熱器的結構分類 可分為:浮頭式換熱器、固定管板式換熱器、U形管板換熱器、板式換熱器等。
