摘　　要：旨在开发一种新型波纹换热翅片金属氢化物反应器,以期满足清洁能源技术领域对高效氢气释放性能的迫切需求。通过可靠的有限元数值模拟,得到了换热翅片结构参数、换热流体流动速度对反应器放氢时间的影响。结果表明:基于有限元数值模型可以准确得到反应器内部温度以及存储容量变化;翅片高度5 mm、翅片长度2.0 mm、翅片数目13为最优的反应器结构,其氢气释放时间比传统圆盘翅片反应器缩短了24%;换热流体流速对放氢速率有明显改善,当Reynolds数从1780增加到11860时,放氢饱和时间从930 s缩短到700 s。此外波纹翅片易于制造的特性,有利于其在工业领域进行大规模的制造和使用。Novel metal hydride reactors with corrugated fins were proposed for the efficient hydrogen release in the field of clean energy technology.Through reliable finite element numerical simulation,the influence of heat exchange fin structure parameters and heat exchange fluid flow rate on the reactor hydrogen release time is obtained.The results show that the desorption rate and heat transfer in reactor can be simulated accurately using the finite element model.The optimized reactor with 5 mm fin height,2 mm fin length,13 fins was obtained,and the hydrogen desorption time for 0.1%(mass)storage capacity is 24%shorter than that of the conventional circular fin reactor.When the Reynolds number of heat transfer fluid increases from 1780 to 11860,the saturation time of hydrogen discharge decreases from 930 s to 700 s.In addition,corrugated fins are easy to be manufactured and have great potential for industrial applications.
