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

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.
