板(ban)(ban)式熱(re)換(huan)熱(re)器是由一(yi)(yi)組(zu)波(bo)紋金屬(shu)板(ban)(ban)組(zu)成(cheng)(cheng)，上有四個(ge)角孔，供傳熱(re)的兩種(zhong)液(ye)體(ti)通(tong)過(guo)。金屬(shu)板(ban)(ban)片(pian)(pian)安裝在(zai)(zai)(zai)一(yi)(yi)個(ge)側面有固(gu)定板(ban)(ban)和(he)活動(dong)壓緊(jin)板(ban)(ban)的框架內，并用夾緊(jin)螺栓(shuan)夾緊(jin)。板(ban)(ban)片(pian)(pian)上裝有密(mi)封墊片(pian)(pian)，將流(liu)體(ti)通(tong)道密(mi)封，并且引導(dao)(dao)流(liu)體(ti)交替地流(liu)至各自的通(tong)通(tong)內，形(xing)成(cheng)(cheng)熱(re)交換(huan)。流(liu)體(ti)的流(liu)量(liang)，物理性質，壓力降和(he)溫度(du)差決(jue)定了(le)板(ban)(ban)片(pian)(pian)的數量(liang)和(he)尺(chi)寸(cun)。板(ban)(ban)片(pian)(pian)的波(bo)紋不(bu)僅(jin)提(ti)高(gao)了(le)湍流(liu)程度(du)并且形(xing)成(cheng)(cheng)許多支(zhi)撐點，足(zu)以承受介質間的壓力差，金屬(shu)板(ban)(ban)和(he)活動(dong)壓緊(jin)板(ban)(ban)懸掛在(zai)(zai)(zai)上導(dao)(dao)桿上并由下導(dao)(dao)桿定位，而桿端則固(gu)定在(zai)(zai)(zai)支(zhi)撐柱上，但如(ru)果其(qi)中(zhong)一(yi)(yi)種(zhong)液(ye)體(ti)或(huo)兩種(zhong)液(ye)體(ti)在(zai)(zai)(zai)螺旋板(ban)(ban)換(huan)熱(re)器內不(bu)止通(tong)過(guo)一(yi)(yi)次(ci)，則接(jie)口(kou)應開(kai)在(zai)(zai)(zai)固(gu)定板(ban)(ban)和(he)活動(dong)壓緊(jin)板(ban)(ban)上，在(zai)(zai)(zai)大多數場合(he)使用單程，所有管(guan)路都連接(jie)固(gu)定壓板(ban)(ban)上，檢(jian)查(cha)拆鞋打開(kai)換(huan)熱(re)器，不(bu)必拆卸管(guan)道。

換熱(re)器先進的(de)板式結構(gou)：

與其他換熱(re)器(qi)相比，墊片可(ke)拆式換熱(re)器(qi)結構緊湊；可(ke)以(yi)在(zai)0.5-1℃的溫差下進行熱交換，設計高達30Bar，處理量可達4500m3/h；改進后的板片導流設計，有效防止板片結垢，提高傳熱系數高可達8000w/m2.k。

螺旋板換熱器可見的(de)經濟效益：

板(ban)(ban)(ban)片均次(ci)成型(xing)，采(cai)(cai)用(yong)高精度的模具。減少板(ban)(ban)(ban)片物(wu)理應力(li)和提高板(ban)(ban)(ban)片的均衡性，大大延(yan)長板(ban)(ban)(ban)片的使(shi)用(yong)壽(shou)命；板(ban)(ban)(ban)片易于接近檢查，便(bian)于手工清洗(xi)。在(zai)(zai)許多場合可以用(yong)逆流沖洗(xi)加以清洗(xi)，日常清洗(xi)不需(xu)耗費太多時間(jian)，無需(xu)專(zhuan)門(men)培訓人員；全部(bu)系(xi)列(lie)采(cai)(cai)用(yong)免粘貼形式(shi)，減少運(yun)(yun)行維護成本，方便(bian)維修。傳(chuan)熱(re)和壓力(li)可以調節，通(tong)過板(ban)(ban)(ban)片的組合在(zai)(zai)傳(chuan)熱(re)系(xi)數和壓力(li)降得調整，得到良好的傳(chuan)熱(re)系(xi)數，從(cong)而減少設(she)備投(tou)(tou)資(zi)(zi)；經濟(ji)型(xing)，由(you)于其(qi)傳(chuan)熱(re)系(xi)數高、安裝和維修簡便(bian)使(shi)得初(chu)期投(tou)(tou)資(zi)(zi)和運(yun)(yun)行維護成本大大降低。

工作原理：

板(ban)(ban)(ban)(ban)式熱(re)交換(huan)器是由(you)一(yi)組波紋金屬(shu)板(ban)(ban)(ban)(ban)組成，上(shang)有四個角孔(kong)，供傳(chuan)熱(re)的(de)(de)兩種(zhong)液體通過。金屬(shu)板(ban)(ban)(ban)(ban)片安裝(zhuang)在(zai)(zai)(zai)一(yi)個側面(mian)有固(gu)定(ding)(ding)板(ban)(ban)(ban)(ban)和(he)(he)活動(dong)壓緊(jin)板(ban)(ban)(ban)(ban)的(de)(de)框(kuang)架內，并(bing)用(yong)夾緊(jin)螺栓夾緊(jin)。板(ban)(ban)(ban)(ban)片上(shang)裝(zhuang)有密(mi)封墊(dian)片，將流體通道密(mi)封，并(bing)且(qie)引(yin)導流體交替地(di)流至(zhi)各自的(de)(de)通通內，形成熱(re)交換(huan)。流體的(de)(de)流量(liang)，物(wu)理(li)性質(zhi)，壓力(li)(li)降和(he)(he)溫(wen)度差決(jue)定(ding)(ding)了板(ban)(ban)(ban)(ban)片的(de)(de)數量(liang)和(he)(he)尺寸(cun)。板(ban)(ban)(ban)(ban)片的(de)(de)波紋不僅(jin)提高了湍流程度并(bing)且(qie)形成許多支撐點(dian)，足(zu)以承(cheng)受(shou)介(jie)質(zhi)間的(de)(de)壓力(li)(li)差，金屬(shu)板(ban)(ban)(ban)(ban)和(he)(he)活動(dong)壓緊(jin)板(ban)(ban)(ban)(ban)懸掛在(zai)(zai)(zai)上(shang)導桿上(shang)并(bing)由(you)下導桿定(ding)(ding)位，而桿端則固(gu)定(ding)(ding)在(zai)(zai)(zai)支撐柱上(shang)，但如果(guo)其中一(yi)種(zhong)液體或兩種(zhong)液體在(zai)(zai)(zai)換(huan)熱(re)器內不止(zhi)通過一(yi)次，則接口應(ying)開(kai)在(zai)(zai)(zai)固(gu)定(ding)(ding)板(ban)(ban)(ban)(ban)和(he)(he)活動(dong)壓緊(jin)板(ban)(ban)(ban)(ban)上(shang)，在(zai)(zai)(zai)大多數場合使用(yong)單程，所有管路都連接固(gu)定(ding)(ding)壓板(ban)(ban)(ban)(ban)上(shang)，檢查拆(chai)鞋(xie)打開(kai)換(huan)熱(re)器，不必(bi)拆(chai)卸管道。
