Abstract

In this study, stress concentration analyses of Printed Circuit Heat Exchanger (PCHE) channels are performed. To accurately determine the stresses at the channel tips, where stress is concentrated, a submodeling technique based on the analysis results of the entire system is employed. In the submodel, elastic and plastic analyses are performed considering the detailed geometric features of the channel tip and irreversible plastic deformation. By analyzing the stresses obtained from both elastic and plastic analyses, the influence of the fine geometric features at the channel tip on the overall stress distribution of the PCHE is examined. Additionally, the maximum von Mises stress values obtained from the elastic and plastic analyses of the submodel are compared to identify stress concentration tendencies and plastic deformation at the channel tip.

본 연구에서는 인쇄 회로 열교환기 채널에서의 응력 집중 해석을 수행하였다. 응력 집중이 발생하는 응력 집중부의 응력을 도출하기 위해 전체 시스템의 해석 결과를 활용하는 부모델링 기법을 사용하였다. 미세한 기하학적 형상과 비가역적 소성 변형을 고려한 부모델의 탄성 및 소성 해석을 수행하였다. 탄성 및 소성 해석에서 얻은 응력을 통해 미세한 기하학적 형상이 PCHE의 응력 분포에 미치는 영향을 파악하였다. 탄성 해석과 소성 해석에서의 최대 폰 미제스 응력을 비교하여 응력 집중부의 응력 집중 경향과 소성 변형을 확인하였다.
