The first part of design is the technology calculation process. Mainly, the process of technology calculate is according 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 second 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 exchanger’s 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 six maps to display.
