Abstract

Abstract

A triangular-inside tube accumulator was proposed to solve the problem of low heat transfer rates of traditional phase change accumulators. Based on the topology optimization, the fins were designed for the purpose of enhancing heat transfer, and the topological results were reconstructed, with the topological characteristics extracted to redesign the fin configuration, and the heat transfer capacities of different fin configurations analyzed. The results show that, the triangular-inside tube accumulators have significant advantages of heat storage and release performances over the traditional circular tube accumulators; the accumulators with topologically reconstructed fins can shorten the heat storage and release time and improve the heat transfer efficiency; in the heat storage process, the bifurcated topology characteristics can improve the natural convection; during the heat release process, the accumulators with topologically reconstructed fins are less entransy dissipative, more reversible and more efficient.
