金字塔型梯形截面通道对印刷电路板式换热器传热性能的影响
Effect of Pyramid-Type Trapezoidal Cross-Section Channels on the Heat Transfer Performance of PCHE
摘要: 本文深入研究并分析了金字塔结构的高度对通道内流动与传热特性以及平均特性等参数的影响，明确了结构高度增加会加剧流动非均匀性并提升阻力损失，且换热强化存在边际效应；得到了综合性能的雷诺数依赖性特征，即Re < 10,000时，hp = 0.14 mm性能最优，而Re > 10,000时，hp = 0.16 mm更具优势，为PCHE的结构参数优化提供了定量指导依据。
Abstract: This paper presents an in-depth analysis of the effects of pyramid structure height on flow and heat transfer characteristics, as well as average performance parameters. It clarifies that increasing the structural height intensifies flow non-uniformity and increases flow resistance loss, while the enhancement in heat transfer exhibits a marginal effect. Furthermore, the study reveals the Reynolds number dependence of the comprehensive performance: the structure with hp = 0.14 mm is optimal when Re < 10,000, whereas hp = 0.16mm demonstrates superior performance when Re > 10,000. These findings provide a quantitative basis for the structural parameter optimization of PCHE.
