摘　　要：计算机的核心部分是CPU,CPU的工作温度密切关系到计算机的使用寿命。在应用ANSYS有限元软件分析的前提下,分析CPU散热片的电磁场和热场分布,并将电磁场和热场作为分析结果来作为热生成率载荷,从而得到CPU散热片内部温度场和热场的分布。用此方法可以很好地减少CPU散热片的制作成本,也可以用来对已运行的机器进行电磁场和热场分布的分析。CPU is the core part of the computer. Its working temperature has close relationship with the service life of the com- puter. Under the premise of analysis using the finite element software ANSYS, the electromagnetic field and thermal field distri- bution of CPU heat sink are analyzed, and the electromagnetic field and thermal field are taken as the analysis result, and as heat generation rate loading, so as to obtain the distribution of temperature field and thermal field inside CPU heat sink. This method can be very good at reducing the CPU heat sink production cost, and can also be used in running machine for analysis of electromagnetic field and thermal field distribution.
