同軸套管換熱器

同軸換熱器，也叫"套管換熱器",由螺旋槽紋內(nèi)管和外套管組成，冷熱流體分別在內(nèi)管和外套管環(huán)隙中流動的換熱器。

結(jié)構(gòu)特點(diǎn)-1	結(jié)構(gòu)特點(diǎn)-2

制冷劑冷卻冷凝后，螺旋槽紋管結(jié)構(gòu)的肋結(jié)構(gòu)上的液膜，受表面張力的作用變薄，降低了傳熱熱阻。	螺旋槽紋結(jié)構(gòu)，能起到雙側(cè)強(qiáng)化換熱的作用，流體在管內(nèi)既有沿軸向的流動，也有沿著螺旋旋轉(zhuǎn)流動，產(chǎn)生局部二次流，加劇了近壁面處流體與中心流體的混合，加強(qiáng)了湍流強(qiáng)度，使傳熱系數(shù)增大

內(nèi)管材質(zhì)	外管材質(zhì)

內(nèi)管材質(zhì)可以為：紫銅，鎳白銅（BFe10-1-1），鈦，不銹鋼，并且內(nèi)管還有光管和經(jīng)過壓花工藝處理的高低效管之分。此外還有銅-銅雙壁結(jié)構(gòu)的內(nèi)管。	根據(jù)不同的使用環(huán)境，外管材質(zhì)可以為：鋼，紫銅，鎳白銅（BFe10-1-1），鈦，不銹鋼，等。

同軸套管換熱器-特點(diǎn)

抗凍性好水在低速流動時，就能在螺紋槽紋管中形成湍流，不易凍結(jié)。獨(dú)有的螺旋槽紋結(jié)構(gòu)，具有良好的伸縮性，不會凍結(jié)致裂。	自除垢、不易堵流體螺旋流動沖刷，具有自除垢能力，性能穩(wěn)定、衰減小。水側(cè)流道具有較大的截面尺寸，容許水中夾帶較大直徑的泥沙、纖維等雜質(zhì)通過，造成臟堵的可能性小。換熱管的多頭螺旋結(jié)構(gòu)使得流體在內(nèi)部流動是處于紊流狀態(tài)，自除垢防垢能力強(qiáng)，通道內(nèi)具有較高的清潔度。
焊點(diǎn)少，承壓好由于螺旋套管換熱器在工藝制造過程中，焊口連接較少，工藝處理易行，焊接質(zhì)量合格，大大降低了系統(tǒng)因長期受振動、壓力波動、冷熱交替沖擊導(dǎo)致接口處開裂發(fā)生泄漏的危險。	換熱效率高螺旋槽紋結(jié)構(gòu)，能起到雙邊強(qiáng)化換熱的作用，流體在管內(nèi)既有沿軸向的流動，也有沿著螺旋旋轉(zhuǎn)流動，加劇了近壁面處流體與中心流體的混合，加強(qiáng)了湍流強(qiáng)度，使傳熱系數(shù)大。
強(qiáng)化換熱 a.內(nèi)管外壁的網(wǎng)紋齒狀結(jié)構(gòu)，增加了流體與管壁的接觸面積； b.內(nèi)管外壁的網(wǎng)紋齒狀結(jié)構(gòu)增加了流體的湍流強(qiáng)度，增大了雷諾數(shù)；齒狀結(jié)構(gòu)能有效減薄流體的邊界層厚度。以上兩點(diǎn)能提高換熱器的換熱系數(shù)，提升換熱效果，增加單位體積的換熱量。	壽命長制冷系統(tǒng)在實(shí)際運(yùn)行中，由于受溫度波動，啟停循環(huán)，熱泵融霜，膨脹閥調(diào)節(jié)等因素的影響，內(nèi)部壓力處于頻繁交替下。在頻繁的振動和壓力變化下，螺旋套管抵抗壓力震動和壓力沖擊的能力要比板片結(jié)構(gòu)高得多，所以能適應(yīng)實(shí)際運(yùn)行工況的復(fù)雜性。

抗凍性好

水在低速流動時，就能在螺紋槽紋管中形成湍流，不易凍結(jié)。獨(dú)有的螺旋槽紋結(jié)構(gòu)，具有良好的伸縮性，不會凍結(jié)致裂。

自除垢、不易堵

流體螺旋流動沖刷，具有自除垢能力，性能穩(wěn)定、衰減小。水側(cè)流道具有較大的截面尺寸，容許水中夾帶較大直徑的泥沙、纖維等雜質(zhì)通過，造成臟堵的可能性小。換熱管的多頭螺旋結(jié)構(gòu)使得流體在內(nèi)部流動是處于紊流狀態(tài)，自除垢防垢能力強(qiáng)，通道內(nèi)具有較高的清潔度。

焊點(diǎn)少，承壓好

由于螺旋套管換熱器在工藝制造過程中，焊口連接較少，工藝處理易行，焊接質(zhì)量合格，大大降低了系統(tǒng)因長期受振動、壓力波動、冷熱交替沖擊導(dǎo)致接口處開裂發(fā)生泄漏的危險。

換熱效率高

螺旋槽紋結(jié)構(gòu)，能起到雙邊強(qiáng)化換熱的作用，流體在管內(nèi)既有沿軸向的流動，也有沿著螺旋旋轉(zhuǎn)流動，加劇了近壁面處流體與中心流體的混合，加強(qiáng)了湍流強(qiáng)度，使傳熱系數(shù)大。

強(qiáng)化換熱

a.內(nèi)管外壁的網(wǎng)紋齒狀結(jié)構(gòu)，增加了流體與管壁的接觸面積；
b.內(nèi)管外壁的網(wǎng)紋齒狀結(jié)構(gòu)增加了流體的湍流強(qiáng)度，增大了雷諾數(shù)；齒狀結(jié)構(gòu)能有效減薄流體的邊界層厚度。
以上兩點(diǎn)能提高換熱器的換熱系數(shù)，提升換熱效果，增加單位體積的換熱量。

壽命長

制冷系統(tǒng)在實(shí)際運(yùn)行中，由于受溫度波動，啟停循環(huán)，熱泵融霜，膨脹閥調(diào)節(jié)等因素的影響，內(nèi)部壓力處于頻繁交替下。在頻繁的振動和壓力變化下，螺旋套管抵抗壓力震動和壓力沖擊的能力要比板片結(jié)構(gòu)高得多，所以能適應(yīng)實(shí)際運(yùn)行工況的復(fù)雜性。
