Structural Design and Finite Element Analysis of High-Pressure Hydrogen Pre-Cooled Printed Circuit Heat Exchanger
本文采用解析法设计印刷电路换热器(PCHE)芯体板片通道,并对芯体板片结构进行优化,然后根据板片尺寸参数建立 PCHE模型,采用有限元法对 PCHE受力情况进行了数值模拟,最后对危险部位进行了应力评定和强度校核.为验证扩散焊芯体的强度,设计制造了一台 PCHE样机用于爆破实验,将爆破实验结果与数值模拟预测值进行对比,预测误差仅为 2.6%,证明了 PCHE设计方法和数值模拟的可靠性.
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.
