本研究的目的是改善酒柜内的温度均匀性。首先提出了四种基本方法，即，本发明采用固体隔板将机柜分隔成多个室，并将冷空气送入每个室中;提供冷气帘，防止热量通过前玻璃门泄漏;调节冷气的流动方向，增强机柜两侧的对流;在机柜底部的不同室中增加出风口，分散回风中的热量。在定性和定量比较各种方法及其组合效果的基础上，推荐了四种方法的组合作为最优方案。优化方案在酒柜中的实际应用表明，柜内最大温差由12.1 °C降低到1.9 °C，效果令人满意。
The purpose of this study is to improve temperature uniformity in a wine cabinet. Four basic methods are proposed at first, i.e., using solid shelves to separate the cabinet into several chambers and sending cold air into each chamber; providing an cold air curtain to prevent heat leakage though front glass door; adjusting the flow direction of cold air to enhance convection in both sides of the cabinet; and adding air outlets in different chambers in the bottom of the cabinet to distract the heat in the return air. Then a combination of these four methods is recommended as the optimal scheme based on qualitatively and quantitatively comparing the effects of these methods and their combination. Practical application of the optimal scheme in a wine cabinet shows that the maximum temperature difference in the cabinet has decreased from 12.1 °C to 1.9 °C, meaning that the effect is quite satisfied.
