style="text-indent:25px">變聲速增壓熱交換器即兩相流噴射式熱交換器，普遍適用于汽—水換熱的各個(gè)領(lǐng)域。它以蒸汽為動(dòng)力，通過(guò)汽水壓縮混合，使水溫瞬時(shí)升高，利用壓力激波技術(shù)達(dá)到無(wú)外力增壓的效果，明顯的節(jié)能和增壓特點(diǎn)較大降低了用戶使用成本，可取代傳統(tǒng)的熱交換器。變聲速增壓熱交換器是一種混合型汽—水換熱設(shè)備，蒸汽經(jīng)過(guò)絕熱膨脹技術(shù)處理以射流態(tài)引入混合腔與經(jīng)過(guò)膜化處理的被加熱水在蒸汽沖擊力作用下均勻混合，形成具有一定計(jì)算容積比的汽水壓縮混合物，當(dāng)其瞬間壓縮密度達(dá)到一定值時(shí)便形成了兩相流體場(chǎng)現(xiàn)象。在場(chǎng)態(tài)的激化下，該混合物的聲速值出現(xiàn)突破聲障臨界的過(guò)渡性轉(zhuǎn)變，同時(shí)爆發(fā)大量壓力激波，壓力激波單向傳導(dǎo)特性使瞬間達(dá)到設(shè)計(jì)溫度的熱水在不變截面管道中出現(xiàn)壓力升高卻不回流現(xiàn)象。換熱器改進(jìn)了傳熱，減少了結(jié)垢，真正的逆流，降低了成本，無(wú)振動(dòng)。</p><div
