- 摘要：文中针对换热器非对称管束结构，采用有限元方法进行建模与力学响应分析。为确保模型的准确性和计算效率，通过合理的简化与假设构建某煤化工装置在用换热器几何模型，并采用 ANSYS软件对换热器进行稳态热分析和静力学分析，获取了关键部位的温度分布和应力分布。研究发现，非对称布管结构导致换热器在热载荷与机械载荷作用下呈现复杂的响应特性，特别是在管板与换热管连接处出现显著的局部应力集中现象。该研究成果可为非对称布管换热器的结构优化设计和安全评估提供理论依据和工程指导。
Abstract: This article focuses on the asymmetric tube bundle structure of heat exchangers and uses finite element method formodeling and mechanical response analysis. To ensure the accuracy and computational efficiency of the model, a geometric model ofthe heat exchanger in use in a coal chemical plant was constructed through reasonable simplification and assumptions. And ANSYSsoftware was used for steady-state thermal analysis and static analysis of the heat exchanger, obtaining the temperature distributionand stress distribution of key parts. Research has found that asymmetric tube structures result in complex response characteristics ofheat exchangers under thermal and mechanical loads, especially significant local stress concentration phenomena at the connectionbetween the tube plate and the heat exchange tube. The research results of this article can provide theoretical basis and engineeringguidance for the structural optimization design and safety evaluation of asymmetric tube heat exchangers.
