摘　　要：高品质酒柜的开发,需要能够保证酒柜内温度场均匀性的设计方法。本文对均匀输送冷量、避免冷气下沉、降低门体漏热、增强空气湍流等四个改进均温性的方向,提出风口布置、隔板布置、顶部风幕布置、风口方向设计这四种初步的方案;通过计算机仿真探讨各方案的效果及各方案优化组合的可能性。计算表明:优化组合四种方案可达到最佳均温性能。将该优化方案应用于某品牌389 L酒柜进行均温设计,样机测试结果显示:在环境温度为32℃,柜内设置温度为8℃的工作条件下,酒柜内最大温差由12.6℃降低至2.0℃,说明该优化方案可有效地提高酒柜的温度分布均匀性。The development of a high-quality wine cabinet requires a method to make the temperature distribution in the cabinet as uniform as possible. In this study,basic ideas for achieving a uniform temperature in a wine cabinet are presented,including a uniform transport of cold air,avoiding the sinking of cold air,reducing door heat leakage,and enhancing the air turbulence. In addition,preliminary schemes are illustrated accordingly,including the arrangement of the air outlet,the division of space,the air curtain on top of the cabinet,and the transverse direction of the air outlet. An optimized scheme was obtained through a comparison and analysis of the simulation performance of each scheme. The results show that the combination of four preliminary schemes can achieve the best temperature uniformity in a wine cabinet. A performance test of a 389 L wine cabinet under a set temperature of 8 ℃ shows that the maximum temperature difference can be reduced from 12. 6 ℃ to 2. 0 ℃ through the optimized scheme at an ambient temperature of 32 ℃. It was verified that the optimized scheme is able to improve the temperature uniformity in a wine cabinet effectively.
