Research And Optimization For The Heat Exchanger Flange By ANSYS Re-develop Technology

With the constant development of the human civilization, the demands for electricity power are becoming increasingly larger in modern society. The more prominent problem is China's energy utilization efficiency is much lower than the developed countries. Therefore, we urgently need to develop new types of energy-saving equipment. So, it is very meaningful to develop the energy-efficient heat transfer equipment. Commissioned in accordance with Hubei Dengfeng Heat Exchanger Company, this paper analysis the design of KLQ-type heat exchanger flange from the following aspects:First of all, from the basic theory of heat exchangers, I established the theoretical model of KLQ-type heat exchanger flange with the classical plate theory and the water Methods which is commonly used in the design of flange. I obtained the formula for calculating the flange stress, at the same time, I established the equivalent flange model by using the finite element software ANSYS through the drawing provided by factory.Secondly, according to the basic principles of ANSYS re-develop technology, I parametric the KLQ-type flange model to meet the use requirements of the re-develop technology. After careful consideration, I proposed two different re-develop programs and the specific use based on different re-develop ideas. At the same time, two options were explored; pointing out the strengths and weaknesses of each, and in accordance with the requirements of the topic, select the appropriate analysis program.Then, I considered the impact on the flange in different working conditions. According to different working conditions, I use different boundary conditions and imposed loads. I get the analysis results of the steady-state temperature field based on the basic principles of thermal analysis. According to the coupling feature of ANSYS thermal-structure, I selected the representative paths to analysis the stress and linearization in different working conditions, and give the Safety Assessment of linear results on the paths to determine their safety and on this basis find the major factor which is impacted the flange performance.Finally, in accordance with the above analysis of the most dangerous working conditions, 1 gave the optimized design which is more economical by many times iterative and gave the safety assessment. The results showed that the design comply with the requirements of the program. It provided a further heat exchanger design ideas.In this paper, I calculated the heat exchanger flange at different boundary conditions and different material parameters. The results of the analysis of the design have certain significance to the manufacture of equipment.
