摘要

拓扑优化肋片能够有效强化相变储热单元的传热与储热性能。通过建立管壳式相变储热单元二维数学模型，对比研究了不同储、放热时间下的最优肋片，开发了适用于不同储、放热循环的多工况肋片，并采用计盒维数、单位长度表面积对肋片结构定量表征。结果表明：增加储热时间使肋片分支更简单且呈非均匀分布；放热时间超过600 s后，肋片向储热单元中部延长以增大表面积。3 000 s储热-放热循环肋片相比于单工况肋片，传热面积增大80%，单位质量放热量提高37.6%；300 s放热-储热循环肋片的分支末端得到了延展，单位质量储热量提高7.7%。

Abstract

Topological fins can significantly improve heat transfer in latent heat storage units. In this study

a two-dimensional topology optimization model for a shell-and-tube latent heat storage unit was developed and experimentally validated. The optimal fin for different operating conditions and charge-discharge cycles was investigated. Box-counting dimensions and fin surface areas per unit length were used to characterize the topological fins. The results showed that increasing the charging time simplified the fin structures

whereas discharging times of more than 600 s extended the fin tips. For the 3 000 s charge-discharge cycle

the optimal fin increased the surface area per unit length by 80% and the discharge energy density by 37.6% compared to the fin for the 3 000 s charging process. The topological fin for a 300 s discharge-charge cycle with an extended branch resulted in a 7.7% increase in heat storage density.
