2、和强度设计。设计的前半部分是工艺计算部分，主要是根据给定的设计条件估算换热面积，从而进行换热器的选型，校核传热系数，计算出实际的换热面积，最后进行压力降和壁温的计算。设计的后半部分则是关于结构和强度的设计，主要是根据已经选定的换热器型式进行设备内各零部件（如接管、折流板、定距管、钩圈、管箱等）的设计，包括：材料的选择、具体尺寸确定、确定具体位置、管板厚度的计算、浮头盖和浮头法兰厚度的计算、开孔补强计算等。最后设计结果可通过6张图表现出来。关键词 换热器 接管 折流板 定距管毕业设计说明书（论文）外文摘要Title The Design of Fixed Tube Sheet Heat Exch

3、anger and Float Head Heat Exchanger AbstractThe design manual is about heat exchanger, which included technology calculate of heat exchanger, the structure and intensity of heat exchanger.The first part of design is the technology calculation process. Mainly, the process of technology calculate is a

4、ccording to the given design conditions to estimate the heat exchanger area, and then, select a suitable heat exchanger to check heat transfer coefficient ,just for the actual heat transfer area .Meanwhile the process above still include the pressure drop and wall temperature calculation . The secon

5、d half of the design is about the structure and intensity of the design. This part is just on the selected type of heat exchanger to design the heat exchangers components and parts ,such as vesting ,baffled plates, the distance control tube, circle hook, tube boxes. This part of design mainly include：the choice of materials，identify specific size, identify specific location, the thickness calculation of tube sheet, the thickness calculation of floating head planting and floating head flange, the opening reinforcement calculation etc. In the end, the final design results through s
