摘　　要：根据相关散热器尺寸,建立散热器锯齿型错列翅片冷流体侧微流道单元模型,采用CFD(Computational Fluid Dynamics,计算流体力学)数值仿真方法对其散热性能进行研究,分析锯齿型翅片结构参数对散热器散热性能的影响。为验证文中模型的准确性及分析方法的正确性,将一组仿真结果与文献数据进行对比,结果表明误差在可接受范围内。分析单元体内空气的温度场和压力场的分布特点,对不同结构参数的翅片进行仿真分析,得到翅片的性能变化曲线,为散热器的设计提供一定的参考依据。The analysis is carried out by construct-ing a unit model for micro current at the cold flow side according to dimensions of the radiator while using CFD numericalsimulation to study the radiator's functions and analyzing how the fin's data affects the functions before comparing simulation results of a group with the documentation data to have shown that the tolerances are acceptable. The analysis covers air temp within the unit body and distribution features in the pressure field with which to simulate and analyze fins in different configuration data to have got functioning variation curves for the fins, thus providing certain references for further radiators design.
