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.
