摘　　要：冰温库对温度的均匀性和稳定性有较高要求,本文对实际使用的冰温库温度进行了模拟分析和实际测量。在冷风机分别为两个和四个出风口时,利用流体力学软件模拟了冰温库在不同出风口形式下的温度分布,同时测量了两种出风口形式下不同截面测点的温度,并与模拟温度进行了对比。结果表明:四个出风口时冰温库的温度分布更均匀。The temperature uniformity and stability of the ice temperature storage must satisfy the demand. The temperature field of ice temperature storage in the actual use was simulated and measured. When the air cooler had two or four air outlet respectively, the fluid dynamics software was used to simulate the temperature field distribution of the ice temperature storage in different air outlet modes. The temperature of different cross section measuring points was measured and it would be compared with the simulated temperature. The results show that the temperature distribution is more Uniform in the four air outlets.
