【摘要】 对穿过冷库阁楼层的柱子建立了三维稳态传热数学模型，对常用的隔热材料，模拟了柱子及其相连的楼板各表面的温度场、热流密度及总传热量、讨论了包柱高度对减少传热量的影响，从理论上给出了包柱高度的有效范围，为实际中采用的经验包柱方法提供了理论基础。更多还原

【Abstract】 Mathematics model of heat transfer in three-dimensional steady state was made for the column through attic floor of the cold storage. The thermal-insulating materials, density of heat current bud capacity of heat transfer in the column were simulated. Therefore, the effect of height of wrapping column on heat transfer, efficient length and construction methods of wrapping column are discussed in the paper.更多还原
