The performance of a heat sink is significantly influenced by the type of cooling used: passive or active (forced), the shape of the heat sink, and the material from which it is made. This paper presents a review of the literature on the influence of geometry and surface parameters on effective heat transfer in heat sinks. The results of simulation studies for three different heat sink fin geometries and cooling types are presented. Furthermore, the influence of the surface texture of the heat sink fins on the heat transfer efficiency was determined. It was shown that the best performance in terms of geometries was that of a wave fin heat sink. When the surface texture was analyzed, it was found that an increase in the amplitude values of the texture decreases the heat dissipation efficiency in the case of active cooling, while for passive cooling, an increase in these parameters has a beneficial effect and increases the effective heat transfer to the surroundings. The cooling method was found to be the most important factor affecting heat dissipation efficiency. Forced airflow results in more efficient heat transfer from the heat sink fins to the surroundings.
散热器的性能受到所采用的冷却方式（被动或主动（强制））、散热器的形状以及制造散热器的材料的显著影响。本文综述了关于几何形状和表面参数对散热器有效传热影响的文献。给出了三种不同散热器翅片几何形状和冷却方式的模拟研究结果。此外，还确定了散热器翅片表面纹理对传热效率的影响。结果表明，就几何形状而言，性能最佳的是波纹翅片散热器。在分析表面纹理时发现，对于主动冷却，纹理振幅值的增加会降低散热效率，而对于被动冷却，这些参数的增加具有有益效果，并会增加向周围环境的有效传热。冷却方式被认为是影响散热效率的最重要因素。强制气流可使从散热器翅片到周围环境的传热更高效。
