摘　　要：在现代生活中,冰箱扮演的角色不可替代。食物的储存质量依赖于冷藏室、冷冻室内的温度分布是否均匀,这是目前风冷冰箱设计中的一个重点。本文介绍了冷冻室结构,分析了出风口的温控区域分布,建立了风冷冰箱冷冻室模块的简化三维模型并进行CFD仿真分析;基于温控区域分布,对层内和层与层之间温度分布不均匀的地方调整该层的出风口,改善了箱室内的温度分布,提高了冷冻室的温度均匀性。In modern life,refrigerator plays an irreplaceable role.The quality of food storage depends on whether the temperature distribution in the refrigerator and freezer is even,which is a key point in the design of air-cooled refrigerator.This paper introduces the structure of the freezer,analyzes the temperature control area distribution of the air outlet,establishes a simplified three-dimensional model of the air-cooled refrigerator freezer module and carries out CFD simulation analysis;based on the temperature control area distribution,adjust the air outlet of the layer where the temperature distribution is uneven within and between layers,improve the temperature distribution in the chamber and improve the temperature uniformity of the freezer.
