列管式 相变储能换热器 由于 具有较大的 储热和换热 速率，引起了 国内外学者 及 工业界人士 的 广泛关注。但是，目前 对 列管式 相变储能换热器 设计 及 储/释过程 实验研究 还较少 且对其 强化 换热机理研究 还不够充分，无量纲化 研究 也鲜有报道。
针对以上几点，对列管式 相变储能换热器 进行 设计实验，并 数值分析了 进口工况、模型结构、相变材料(PCM)物性 及 相变材料组合 对 储热换热性能 的影响，并对 填充定型 相变材料 列管式 相变储能换热器 的研究参数 进行了 无量纲化。
Since with higher efficiency of heat exchanging and heat accumulation, tube-type phase-change energy storage heat transfer has attracted great attention from world wide scholars and people in industrial community. However, currently there are few experimental researches on the design and storage/release process of tube-type phase-change energy storage heat transfer, insufficient researches on the enhancement of its heat transfer mechanism, nor very few reports about its non-dimensionalization research. Regarding above few points, in this paper, the experiment on the tube-type phase-change energy storage heat transfer was designed; numerical analysis was conducted on the influences of inlet conditions, model structure, PCM properties, and PCM combination to the performance of heat exchanging and heat accumulation; moreover, the parameters of the shaped tube-type phase-change energy storage heat transfer were nondimensionalized. |
