摘　　要：本文采用了一种更加节能高效的新型岩心冷柜存放岩心,重点研究了不同堆码方式对新型冷柜内岩心储存因素的影响。基于冷柜实际结构,通过相似性原理进行计算,搭建冷柜模型实验台,建立冷柜中空气与岩心的流固双向耦合模型,分析不同堆码方式下冷柜内气流组织的规律,为岩心储存提供依据。在上送上回的送风方式下,本文研究了满柜以及三种半柜堆码方式下冷柜内温度分布以及气流速度分布,研究结果表明,不同的货物堆码方式对冷柜内温度分布和速度分布有较大的影响,半柜岩心储存时应首先堆码第四、五、六层,温度分布最均匀,温度最低。In this paper,a new type of more energy efficient core freezer is used to store the core,and the influence of different stacking methods on the core storage factors in the new freezer is studied.Based on the actual structure of the refrigerator,the similarity principle was used for calculation,the refrigerator model test platform was built,the fluid-solid two-way coupling model of air and core in the refrigerator was established,and the law of air distribution in the refrigerator under different stacking methods was analyzed to provide a basis for core storage.In the air supply mode of up and back,this paper studies the temperature distribution and air velocity distribution in the freezer under full and three half-tank stacking modes.The research results show that different cargo stacking modes have a great impact on the temperature distribution and velocity distribution in the freezer,and the fourth,fifth and sixth layers should be stacked first when the half-tank core is stored.The temperature distribution is the most uniform and the temperature is the lowest.
