摘　　要：对CPU散热器冷却端空气(以后简称空气夹层)和散热肋片建立了三维计算模型,通过对空气夹层与散热肋片之间的耦合计算,不仅分析散热肋片内温度场的分布规律,而且分析空气夹层的流场和温度场的分布规律,还研究了散热肋片材料对其传热性能的影响,并指出了此种散热器设计上的不足,为CPU散热肋片的设计提供必要的理论依据.Three-dimensional calculation model is set up for air and fin of radiator of CPU. The couple heat transfer between air and fin is calculated. The temperature and velocity distribution of air and fin is not only computed, but also the influence ofmatefial of the radiator to heat transfer of fin is investigated. The defect area of heat transfer in the radiator of CPU is found, the result are useful for the design of the heat sink with efficient performance and further research.
