铲削成形多孔翅片强化散热有限元分析与测试
Analysis and Experimental Study of Enhanced Heat Dissipation of Perforated Fin Radiator Formed in Planning Process

对铲削成形多孔翅片散热器结构进行了湍流和固体传热耦合分析。从铲削工艺的特性出发，研究了翅片间距、厚度、开孔密度、孔径等参数对其散热效果的影响。利用自主研发的铲削工艺加工出铝基材料多孔翅片，进行了实际散热效果测试，验证了分析结果的正确性。
In order to investigate the influences of the structural parameters (such as fin spacing distance, fin thickness, hole density, hole diameters, etc.) on the heat dissipation performance of perforated fin radiator formed in the planning process, multi-physics simulation coupling turbulent fluid flow and solid heat transfer were carried out. The simulated results showed that the heat dissipation efficiency could be enhanced with the increasing of the fin spacing distance, hole density, hole diameter, and with the decreasing of the fin thickness
