自60年代開始，為了適應(yīng)高溫和高壓條件下的換熱和節(jié)能的需要，典型的管殼式換熱器也得到了進(jìn)一步的發(fā)展。70年代中期，為了強(qiáng)化傳熱，在研究和發(fā)展熱管的基礎(chǔ)上又創(chuàng)制出熱管式換熱器。換熱器中流體的相對(duì)流向一般有順流和逆流兩種。順流時(shí)，入口處兩流體的溫差比較大，并沿傳熱表面逐漸減小，至出口處溫差為**小。逆流時(shí)，沿傳熱表面兩流體的溫差分布較均勻。在冷、熱流體的進(jìn)出口溫度一定的條件下，新疆傳熱系數(shù)高換熱器哪家便宜，當(dāng)兩種流體都無相變時(shí)，以逆流的平均溫差比較大順流**小。在完成同樣傳熱量的條件下，采用逆流可使平均溫差增大，換熱器的傳熱面積減小；若傳熱面積不變，采用逆流時(shí)可使加熱或冷卻流體的消耗量降低。前者可節(jié)省設(shè)備費(fèi)，后者可節(jié)省操作費(fèi)，故在設(shè)計(jì)或生產(chǎn)使用中應(yīng)盡量采用逆流換熱，新疆傳熱系數(shù)高換熱器哪家便宜。當(dāng)冷、熱流體兩者或其中一種有物相變化(沸騰或冷凝)時(shí)，由于相變時(shí)只放出或吸收汽化潛熱，流體本身的溫度并無變化，新疆傳熱系數(shù)高換熱器哪家便宜，因此流體的進(jìn)出口溫度相等，這時(shí)兩流體的溫差就與流體的流向選擇無關(guān)了。除順流和逆流這兩種流向外，還有錯(cuò)流和折流等流向。在傳熱過程中，降低間壁式換熱器中的熱阻，以提高傳熱系數(shù)是一個(gè)重要的問題。熱阻主要來源于間壁兩側(cè)粘滯于傳熱面上的流體薄層(稱為邊界層)。上海板換機(jī)械設(shè)備有限公司專業(yè)為您提供板式換熱器。新疆傳熱系數(shù)高換熱器哪家便宜</p><div

2）、地下土壤越深，地下水越豐富。有些地區(qū)還存在著地下水流動(dòng)情況，這樣就產(chǎn)生了對(duì)流換熱，促使熱量擴(kuò)散。深度越深，循環(huán)水所走的路徑越長(zhǎng)，水力損失越大。圖1-7所示，40mC井與60mB井的壓力損失相同是因?yàn)镃井比B井多走了20m的水平管?；旧厦棵坠苈返膲毫p失為75Pa。不同深度鉆孔，循環(huán)水在管路內(nèi)所走的長(zhǎng)度不同，換熱程度也不同，從而進(jìn)出口的溫差也不同。從圖1-8可知，20m深的鉆井溫差很小，很容易受到室外環(huán)境的影響。40m深鉆孔的溫差勉強(qiáng)符合機(jī)組的運(yùn)行狀態(tài)點(diǎn)。鉆井深在60m~100m之間，進(jìn)出口溫差在℃～5℃之間，正處在機(jī)組運(yùn)行參數(shù)范圍之內(nèi)。進(jìn)出口溫差以直線的軌跡隨鉆孔深度的增加而遞增。遞增直線方程為：Y=。當(dāng)鉆井深度為200m時(shí)，進(jìn)出口溫差就上升到℃。此時(shí)溫差嚴(yán)重偏離機(jī)組運(yùn)行狀態(tài)點(diǎn)。若減小溫差，有效的辦法就是提高循環(huán)水的流速。但進(jìn)一步加大管路的水利損失，會(huì)造成能量的浪費(fèi)。從而，根據(jù)實(shí)際工程情況，推薦鉆孔深在60m~100m之間。圖1-9是通過比較實(shí)驗(yàn)測(cè)試熱阻與理論模型計(jì)算熱阻，反應(yīng)深度對(duì)土壤導(dǎo)熱系數(shù)測(cè)試結(jié)果的影響程度。各鉆孔的實(shí)驗(yàn)與理論熱阻誤差非常小，在圖1-9上兩者基本上是重合的。</p><p>
