u型管式换热器结构紧凑，体形小，节省站房用地面积和建筑高度(占地面积为一般管壳式换热器的1／2 左右，高度可降30~40%）。节省建筑投资，便于设计布置，同时运行操作方便。换热性能好，热媒出口温度低，热能利用率高，节能效果好。传热系数高，节省换热面积(tqn、tqk)汽水换热器的传热系数(k值)比板式汽水换热器的实际使用传热系数大一倍左右，换热面积可减少40-60％。水力特性好，热媒和被加热水的流动阻力小，节能效果好。 u型管汽水换热器排出的凝结水温度低(tqk)系列在65℃以下，(tqn)系列在80℃ 以下，既无漏汽损失，也不需要装疏水器，管道系统简单，散热损失小。
u型管汽水换热器的管间间距比一般管壳式换热器的管间间距大，每个换热单元的尺寸和重量较小，便于维护清洗。
u tube heat exchanger structure is compact, small size, saving station building land area and the height of the building (which covers an area of over generally about half of the tube and shell heat exchanger, the height is 30 ~ 40%). save construction investment, facilitate design layout, convenient for operating at the same time. good heat transfer performance, low outlet temperature of the heat medium, high heat energy utilization, energy saving effect is good. heat transfer coefficient is high, can save heat exchange area (tqn, tqk) soft drinks heat exchanger heat transfer coefficient (k value) larger than the actual use of board type soda heat exchanger heat transfer coefficient times the left and right sides, so the heat exchange area can reduce 40-60%. good hydraulic characteristics, heat transfer and the heated water flow resistance is small, energy-saving effect is good. soda u-shaped tube heat exchanger of the condensate temperature low (tqk) series under 65 ℃, (tqn) series under 80 ℃, no steam leakage loss, also do not need to install hydrophobic, pipeline system is simple, small heat loss.
u tube spacing between soft drinks heat exchanger tube than the average of tube and shell heat exchanger tube spacing between big, smaller size and weight of each heat exchange unit, easy to maintain clean.
