微型汽车散热器百叶窗翅片高度的优化设计

摘要

In order to get more reasonable structure of radiator shutters fin in micro car , the software Fluent is introduced to perform numerical analysis for the radiator fins. By modifying the key size (fin height), it is successfully to get resistance factor f and the heat factor j for the radiator fins with different heights, and the overall performance is evaluated by introduction of non-dimensional parameter jlf1/3. The optimized result shows that when the fin height is 8.94 mm, the overall performance will be the best.%为了得到更合理的微型汽车散热器的百叶窗翅片结构,采用Fluent软件,对散热器翅片进行了数值分析.通过修改其关键尺寸(翅片高度),得到了不同高度下散热器翅片的阻力因子f和散热因子j,并引入无量纲参数j/f1/3来评价其综合性能.优化结果是当翅片高度为8.94mm时,综合性能最佳.
