摘　　要：引入了CFD软件对两款常见的恒温箱(上出风型和下出风型)做了气流组织模拟并进行了实验验证。模拟值与实验值能较好地吻合,最大绝对误差不超过0.04 m/s。结果显示:上出风型恒温箱由于其扰流强度较大,能很快地使待测品达到预定温度,而下出风型恒温箱的气流均匀性较上出风型好。In order to know the air distribution of the two sizes of thermostat（ outlet on the top, outlet down below）, the CFD was used to simulate. The computing results matched with the experimental results. The maximal absolute error was below 0.04 m/s. The results showed that one outlet on the top can make need checking sample to get target temperature quickly because of its strong flow perturbation . On the other hand, the airflow distribution uniformity of the one outlet down below is better than outlet on the top.
