Abstract: In today's society, saving resource is a very important issue. Heat exchangers arewidely used in various industries, energy saving and heat transfer enhancement has been paidmore and more attention.This paper is mainly based on the different cooling capacity, importand outlet sea water temperature. According to the structure of copper tube and titanium screwpipe heat exchanger, to calculate the water flow, velocity of flow, heat medium and refrigerantheat transfer coefficient, light tube resistance,threaded pipe length and resistance.By using VBto design titanium threaded pipe heat exchanger instead of copper tube heat exchanger.Thissubject can also compare different refrigerants, thread pitch, thread depth, rib thickness andthread angle to optimize the design of titanium screw pipe heat exchanger.According to theresearch, the same length of the threaded tube heat transfer effect is 1-2 times of light pipe. Inthis way, the heat exchanger can be enhanced to a large extent, the volume of the heatexchanger is reduced and the energy is saved.

1 绪论当今社会，换热器已经应用于多个行业多个领域之中，包括石油、化工、养殖等。在不断的开发研究中，人们重心逐步放在能源节约、环境保护等上面，因此对换热器的要求也越来越高，强化传热不断被重视，高效换热器成为新宠，国内外先后推出了一系列的新型高效换热器[1]。钛炮换热器是一种由优质钛管制成的换热设备，它将热流体的部分热量传递给冷流体。由于钛的抗腐蚀能力强，所以换热器的使用寿命长、并且在使用中维护费用也少。钛材料加上螺纹螺旋制成的换热器，不仅体积小，而且换热能力比较强，在海水养殖中大大提高了换热效果。1.1 钛炮简介钛炮又名纯钛蒸发器，它广泛应用于海水养殖换热、食品、化工、医疗等领域。钛对海水、氯碱、醋酸等有较好的抗腐蚀能力，表面不易产生氧化层，不污染介质，环保无毒，适用于热水、油、酸、碱等溶液与蒸汽、冷热水的换热。与之类型相同的产品还有钛管蒸发器、钛加热管、钛壳管换热器、钛盘管等。
