蓄冷保温箱的研究进展

Research progress of cold storage type incubator

随着相变储能技术的发展,未来蓄冷保温箱将会更加环保、节能、耐用,并会对食品冷链运输产生积极的影响。文章综述了蓄冷保温箱所用的有机、无机和复合相变三类蓄冷剂,以及近年来国内外开发的微胶囊蓄冷剂、纳米蓄冷剂等新型蓄冷剂;从保温材料和温度场均匀性两方面阐述了蓄冷保温箱设计优化的进展,提出新型保温材料结构的可行性以及箱内温度场的影响因素。研发高效环保的蓄冷剂,优化的保温结构以及温度场均匀性是今后蓄冷箱研究的重点。

With the development of phase change coolants and insulation technologies,it is expected that the cold storage incubators will be more economical,environmentally friendly,and durable,and have a positive impact on cold chain logistics and people’s lives.Firstly,three types of organic,inorganic,and composite phase-change coolants used in cold storage incubators,as well as new cold storage agents such as microcapsule cold storage agents and nano-coolant developed in recent years were reviewed.Then,from thermal insulation materials and temperature fields,in terms of uniformity,the progress of design optimization of cold storage incubator were expounded,and the feasibility ofthe new thermal insulation material structure and the influencing factors of the temperature field inside the tank were proposed.The development of efficient and environmentally friendly coolants,optimized insulation structure and temperature field uniformity are the focus of future research on cold storage tanks.
