摘要
金属氢化物(MH)储氢系统的热管理是保障MH系统吸放氢性能的关键因素之一。MH材料的低有效导热系数为热量传输带来了极大的挑战。迄今为止,在理论和实验工作中已经研究了各种热管理技术以提高吸放氢速率和容量。从床体导热系数增强设计、传热面积增强设计、热交换器设计和热量供给策略等角度全面总结和回顾了近年来报道的MH储氢热管理方案,重点关注传热性能和吸放氢性能的变化,考察不同热管理方案的优势和劣势。最后,对未来的MH储氢系统设计提供了一些建议。
The thermal management of metal hydrides(MH)hydrogen storage systems is one of the key factors to ensure the hydrogen absorption and desorption performance of MH systems at desired levels.However,the low effective thermal conductivity(ETC)of MH beds brought a great challenge for heat transfer.Up to now,various thermal management techniques have been investigated theoretically and experimentally to improve the rate and capacity of hydrogen adsorption desorption.This paper summarized and reviewed the reported MH hydrogen storage thermal management schemes in recent years from the aspects of heat conduction enhancement design,heat exchanger area enhancement design,exchanger design and heat supply strategy,etc.,and focused on the heat transfer performance and hydrogen absorption desorption performance of the changes,the advantages and disadvantages of different thermal management systems.Finally,some suggestions for the future MH hydrogen storage system designs were provided.
