摘要
冰箱冷藏室内搁物架的结构形式及其放置位置对冷藏室内温度场和流场的分布有较大的影响。以FLUENT前处理软件GAMBIT为建模工具，对冰箱冷藏室建立了三维计算模型，划分网格后，用计算流体力学软件FLUENT对网状和平板状搁物架的冰箱冷藏室内的温度场和流场分别进行了仿真，对比仿真结果发现：采用平板式搁物架，并使其与蒸发器所在后壁面之间保持2～3cm间距的结构形式，既能减小各层内部的温度差又能增强换热，是一种比较合理的结构。
The structure of shelf greatly influences the temperature field and flow field distribution inside refrigerator. A three-dimensional computation model is founded with GAMBIT. The fluid dynamics computation software FLUENT is used to simulate the temperature field and flow field inside the refrigerator with reticulate-shelf and plate-shelf structure. The simulation result indicates that adopting the structure of plate-shelf, which keeps a distance of 2-3cm from the back wall where the evaporator locates, is preferable. It can decrease the temperature difference on each layer and at the same time enhance the heat exchange.
