The construction cost ratio of general heat transmission equipment in the chemical industry and oil refining installations can reach 20% to 50%.Therefore, no matter from energy use, or from the factory investment perspective, a reasonable choice and design of heat exchanger have important significance. In all kinds of heat exchanger, as tubular heat exchanger can provide large heat exchanger area per unit volume, heat transfer effect is good, adaptability is strong, elasticity of operation is big, easy to manufacture, its cost is low, easy to maintenance and clean etc, so it is most widely used. The aim of this design is based on the design of equipment to master its equipment basic design method and procedure. The design of the equipment is ushaped tubular heat exchanger. It belongs to the tubular heat exchanger. The design and analysis of Tubular heat exchanger consists of thermal design, flow design, structural design and strength design. Thermal design is the most important. Through this design we know design content of tube exchanger mainly consists of determining design program according to heat task and relevant requirements, determining the structure and size of heat exchanger, accounting heat transfer area and fluid resistance of the heat exchanger, determining process structure of heat exchanger.
