摘　　要：建立了冷藏柜的物理数学模型,并用SIMPLE方法计算冷藏柜内空气的自然对流,得到柜内空气相应点的温度变化情况;同时对相应点的温度变化过程进行了实验研究。实验结果与理论计算结果能较好的吻合,模拟温度与实验温度的差值在1℃以内,从而验证了数学模型的正确性和计算程序的可靠性。The numerical model of the refrigerated counter was established, the natural convenient of the air in the refrigerated counter was calculated with SIMPLE algorithm and the changer of temperature in the counter was got. With the error between simulation and experiment temperature was less than 1 ℃, the experiment result agreed well with the theory and indicated the rightness of the numerical model and the reliability of the program..
