                Abstract
                 
                Tube shell type heat exchanger as fixed tube plate heat exchanger, a structure with a representative, is the more extensive application of a heat exchanger. This heat exchanger has many characteristics: simple structure, compact, wide range of application, high safety factor, a wide range of materials, low cost, heat exchanger surface cleaning is very convenient. Due to the fixed tube plate heat exchanger can withstand higher operating temperatures and pressures, so this kind of heat exchanger occupies a great advantage in all kinds of high temperature and high pressure anlarge heat exchanger.
                Heat exchanger is a simple with different temperatures of two or more fluid between heat transfer equipment. In industrial production process, different kinds of heat exchange process, its main function is the heat transfer by the high temperature of the fluid to fluid temperature is low, the fluid temperature to process indicators, to meet the needs of the production process. In addition, heat exchanger and recovery of waste heat, waste heat, especially an effective device for low grade heat energy.
                Fixed tube sheet heat exchanger composed of a tube box, shell, tube sheet, pipe and other parts, the structure is compact, discharge tube is more, in the same diameter area is larger, the manufacture is simple.
                Fixed tube is the structural characteristics of plate heat exchanger tube bundle is arranged in the shell, welding or expansion joint method for both ends of the pipe bundle fixing pipes on the tube plate, at both ends of the tube plate directly and shell welded together, the import and export of the shell pipe is directly welded on the shell, plate outer circumference and sealing flange with bolts, the import and export of the tube side of the tube and head directly welded together, in the tube bundle according to the length of the heat exchange tube is set a plurality of folded plate. The heat exchanger tube side can be used in any way is divided into several partitions.
                For the pros and cons of heat exchanger design ultimately depends on whether the application, economic, security, reliable and flexible operation, maintenance is convenient to clean, and so on. A heat transfer efficiency high, compact, low cost, safe and reliable for heat exchanger produced, requirements in design carefully consider all kinds of problems. Accurate thermal design and calculation, but also for strength check and conform to the requirements of manufacturing process levels.
                In order to in accordance with the requirements of the design of fixed tube plate heat exchanger, mechanical structure design and drawing of access to GB151-1999< tube shell heat exchanger heat exchanger > and GB150-2011< steel pressure container > and GB and JB standard.
                Standard parts of the selection of the main steps, design of connecting structure between the parts, parts and materials selection and calculation of thickness. Including the head, cylinder, the calculation of tank wall thickness and tube plate tube, stability check and pipe rato force, support, pressure vessel flange, took over the flange, took over the selection and the tube plate and the shell is connected between the structure design, heat exchangers and pipe plate is connected between the structure design, baffled, opening reinforcement design.
                With the rapid development of economy, convenience of our life because of the existing achievement of science and technology has been a qualitative leap, for heat exchanger design technology is also in constantly upgrading, the future prospects of design and application prospects will be brighter.
                Short . rod meet the change  ( to consider . income on the basis of the  Cheng, Cheng Cheng, pipe, tube, Cheng, as known condition: the design pressure for tube side  shell  working temperature range  shell  design temperature range  shell  tube medium  water shell medium water vapor. The given conditions the heat transfer area of the medium characteristic factors, the diameter of 25 x 2.5 x 3000 materials) seamless steel tube, the design of the heat pipes heat. Set number is 7, the calculated cylinder diameter of the pressure drop calculation, strength calculation, opening reinforcement, tube box wall thickness calculation. In the strength design, according to  cylinder head strength of Design and verification, according to the flow of inlet pipe, outlet nozzle and orifice diameter selection, based on area method of reinforcement of ringent strength calculation. The tubesheet extended as flange concurrently, according to the  elastic support hypothesis of tube sheet design and verification, the tube plate and the heat exchange tube and the connection mode of welding, the pull rod and the tube plate is threaded connection structure.
                The design of full use of materials, for more occasions.410 root tube shows that the heat transfer efficiency of heat exchange. In the same for heat exchanger in the heat exchanger is very cheap. Security. Therefore, the change heat exchanger in the factory occupies an important position.
