摘　　要：由于计算机的体积不断缩小,CPU散热器的散热效果对CPU工作性能的影响越加明显,在智能计算机的有限空间散热问题值得深入讨论和研究。本文利用ANSYS软件建立了CPU散热器的三维有限元模型,对其进行热学性能分析。通过改变散热器鳍片角度得到了散热器的温度分布云图和热梯度分布云图,然后对离散数据进行线性拟合,分析了不同角度的散热器鳍片分别与最大温降、热流量、最大长度值之间的函数关系。研究表明,不同角度的鳍片对散热器的散热效果产生一定的影响,为散热器的优化设计提供了重要依据。CPU heat sink dissipation condition has increasingly influence on CPU performance due to a constantly lessening of the computer size, which is worthy of further discussion and research in the limited space of intelligent PC. In this paper, there is using the ANSYS software to set up a three-dimensional finite element model of the CPU heat sink to analyze its themial performance. Radiator temperature distribution images and thermal gradient images are calculated by changing the radiator fin angle, and then the discrete data are f it. Finally, the function relationship between the values of the maximum temperature drop, heat flow, the maximum length and the different angles’ fins are analyzed. Studies have shown that the heat sink fins at different angles have some effect on dissipation condition, which provides an important basis for the optimal design of heat sink.
