蓄冷箱在疫苗冷链中的研究进展

Research Progress of Cold Storage Insulation Box in Vaccine Cold Chains

每年疫苗产品损耗的主要因素之一是冷链运输的失效,在运输过程中使用最为普遍的设备是蓄冷箱。影响蓄冷箱保温性能的因素主要包括保温箱体的绝热性能、蓄冷材料的蓄冷能力及保温包装方式的设计。本文综述了蓄冷箱在疫苗冷链中的研究进展,分析了疫苗蓄冷箱常用保温材料及相变蓄冷材料的选择和应用,并讨论了箱体热阻的计算及蓄冷箱温度的监控。在此基础上指出整体包装和开发相变蓄冷材料的研究方向。

One of the major factors in the annual loss of vaccine products is the failure of cold-chain transportation,where the most common piece of equipment used during transport is the cold storage box.The main factors that influence the performance of a cold storage box include the heat-insulating property of the thermal insulation material,the cooling capacity of the storage material,and the design of the thermal insulation packaging.This study reviews the research progress on cold storage boxes in the vaccine cold chain.The selection and application of common insulation materials and phase-change cold storage materials for vaccines were analyzed,and calculations related to the thermal resistance of the box and the monitoring of the temperature were studied.The research direction for integrated packing and development of phase-change cold storage materials were also proposed.
