Structural Design and Finite Element Analysis of High-Pressure Hydrogen Pre-Cooled Printed Circuit Heat Exchanger
摘要
Abstract
In this paper,the plate channels of printed circuit heat exchanger(PCHE)core is designed by analytical method,and the core plate structure is optimized.Then PCHE model is established based on the plate size parameters.The finite element method is used to numerically simulate the force condition of the PCHE.Finally,stress analysis and strength check are performed on the dangerous parts.To verify the strength of diffusion welded core,a PCHE prototype is designed and manufactured for burst test;the result of the burst test is compared with the value predicted by numerical simulation,and the prediction deviation is only 2.6%.The reliability of PCHE design method and numerical simulation is demonstrated.关键词
