在低溫流體換熱器把熱量釋放給低溫流體。4、直接接觸式換熱器又被稱(chēng)為混合式換熱器，這種換熱器是兩種流體直接接觸，彼此混合進(jìn)行換熱的設(shè)備，例如，冷水塔、氣體冷凝器等。5、復(fù)式換熱器兼有汽水面式間接換熱及水水直接混流換熱兩種換熱方式的設(shè)備。同汽水面式間接換熱相比，具有更高的換熱效率；同汽水直接混合換熱相比具有較高的穩(wěn)定性及較低的機(jī)組噪音。二、按用途分類(lèi)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(méi)有發(fā)生相的變化。2、預(yù)熱器預(yù)熱器預(yù)先加熱流體，為工序操作提供標(biāo)準(zhǔn)的工藝參數(shù)。換熱器3、過(guò)熱器過(guò)熱器用于把流體（工藝氣或蒸汽）加熱到過(guò)熱狀態(tài)。4、蒸發(fā)器蒸發(fā)器用于加熱流體，達(dá)到沸點(diǎn)以上溫度，使其流體蒸發(fā)，一般有相的變化。三、按結(jié)構(gòu)分類(lèi)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。折疊編輯本段行業(yè)狀況折疊概述換熱器在石油、化工、輕工、制藥、能源等工業(yè)生產(chǎn)中，常常用作把低溫流體加熱或者把高溫流體冷卻，把液體汽化成蒸汽或者把蒸汽冷凝成液體。換熱器既可是一種單元設(shè)備，如加熱器，福建換熱器聯(lián)系方式、冷卻器和凝汽器等；也可是某一工藝設(shè)備的組成部分，福建換熱器聯(lián)系方式，如氨合成塔內(nèi)的換熱器，福建換熱器聯(lián)系方式。換熱器是化工生產(chǎn)中重要的單元設(shè)備。上海板換機(jī)械設(shè)備有限公司提供多種類(lèi)型的板式換熱器。福建換熱器聯(lián)系方式</p><div
