摘　　要：用Simple方法计算-65℃冷柜内空气自然对流,得到了冷柜内各个点空气的物性参数. 通过编程绘制了冷柜内空气的温度场、速度场、压力场及密度场,并且对所得场进行了分析.The air flow and heat transfer inside a -65℃ freezer is studied in the paper. A computer programme using the method of Simple is developel to compute the air convection in freezer. With the programme, the temperature and velocity fields in freezer are gained with the results which are very close to experimented ones. Furthermore based on the computed results, some suggestions to improve the homogeneity of air temperature in freezer are presented.
