摘要: 风冷冰箱风道结构特性直接影响整机风量与间室风量分配,对冰箱的性能影响较大。利用CFD方法,对某型号三门变温冰箱进行风道系统整机仿真。通过对内流场分析,优化风道结构,消除流场涡旋。调整风口布局,改善间室风量分配。最终使整机风量由14.8 g/s提升到17.3 g/s,变温室风量提升了36%。开展实验验证,冰箱温度分布有较大改善,可靠性实验合格。

Abstract: Air-cooled refrigerator air duct structure characteristics directly affect the whole air volume and air volume distribution between rooms, which has a large impact on the performance of the refrigerator. CFD method is used to simulate the whole air duct system for a model of three-door variable temperature refrigerator. Through the analysis of the internal flow field, the air duct structure is optimized to eliminate the flow field vortex. The air outlet layout is adjusted to improve the air volume distribution between rooms. Finally, the whole air volume was improved from 14.8 g/s to 17.3 g/s, and the air volume of the variable temperature room was improved by 36%. Carrying out experimental verification, the refrigerator temperature distribution has been greatly improved, reliability test pass.
