Heat exchanger is a general equipment, and played an important role in manufacture, which usually used in Chemical, petroleum, power, food and many other industrial sectors, In the chemical production, it can be used as a heater, cooler, evaporator, condenser and reboiler. There are variety of heat exchangers, however, According to the thermal fluid heat, cold exchange principle and different modes, That basically can be divided into three categories: wall type, mixed type and regenerative type. The design consideration of the properties, temperature, pressure and other factors for a given medium, I select tubular heat exchanger and float head heat exchangers According to the standard of the literature GB150-1998《Steel pressure vessel》，GB151-1999《Shell and tube type heat exchanger》，《heat exchanger design handbook》, I design and check part of the structure and strength of the floating head heat exchanger, in which main components including cylinder, head, tube box, hook and loop type floating head and saddle. In this design, I carefully analyzed the stress of dangerous section wi
