【摘 要】风冷冰箱,在现阶段的社会生产、生活过程中占据着十分重要的地位,能够有效便利人们的生活。风冷冰箱主要承担制冷保鲜的任务,针对其本身的各项结构情况进行全面细致地分析,全面研究其运行原理,能够为充分发挥风冷冰箱的作用提供良好的前提条件。基于内流场分析的风冷冰箱结构优化设计,从实际情况出发,结合Fluent软件,全面分析和寻找到风冷冰箱中需要改进的地方。论文主要从Fluent的分析计算工作入手,针对基于内流场分析的风冷冰箱结构优化设计情况进行全面细致地分析和研究。
【Abstract】Air-cooled refrigerators, occupies a very important position in social production and people′s living process at this stage, can effectively facilitate people's lives. Air-cooled refrigerator is mainly responsible for the refrigeration and refreshment tasks, for comprehensive and detailed analysis of the structure of its own, a comprehensive study of its operation principle, can provide good conditions to give full play to the role of air-cooled refrigerator. Based on the analysis of internal flow field, the structure optimization design of air cooled refrigerator is carried out. From the actual situation, combined with the Fluent software, a comprehensive analysis and search of the need to improve the air-cooled refrigerator. In this paper, from the analysis and calculation of Fluent, the optimum design of air-cooled refrigerator based on internal flow field analysis is analyzed comprehensively and carefully.

1 引言
在风冷冰箱中,能够有效发挥制冷保险作用的关键性结构较多,其中的制冷保鲜功能能够起到良好效果的关键在于储藏室内的气流循环和箱内温差。从内流场分析情况入手,针对风冷冰箱结构方面进行全面有效的优化和改进,这为充分发挥风冷冰箱的优势和作用提供了良好的前提条件。
2 Fluent的分析计算工作
针对风冷冰箱进行全面分析,构建物理模型的過程中,需要从具体的风冷冰箱实际情况出发,比如说某风冷冰箱除却相应的外壳、隔板等部分,本身的体积并不是很大,大约是0.3m3,同时针对其风道结构进行全面观察,能够发现其表现为对称式的结构形式。
2.1 合理构建风冷冰箱的物理模型
从风冷冰箱的常见情况出发,积极构建起相应的物理模型,针对其进行全面细致地分析和研究。……
