排式热管群构造CPU散热器的仿真分析

Thermal Simulating Analysis on the CPU Heat Sink With Heat Pipe Groups

为了验证研制出的CPU散热器的散热效果,利用有限元分析软件ANSYS对该CPU散热器进行了散热分析．研究了在室温和自然对流条件下,同等尺寸的普通CPU散热器和热管式散热器的温度场分布．研究结果表明,所建议的热管式CPU散热器能有效地降低CPU的温度．

In order to test and verify the heat radiation of the CPU heat sink, the authors have conducted a thermal simulating analysis on the basis of ANSYS program of FEM. Temperature distributions of a normal CPU heat sink and the CPU heat sink with heat pipe in the conditions of room temperature and natural convention have been acquired. The results show that the surface temperature of CPU can be reduced efficiently with a heat pipe heat sink.
