Finite element analysis and die design in extrusion processes of heat sinks for CPU

by Chen, Ho-Chen

Abstract (Summary)
This paper uses a finite element code¡©DEFORM 3D¡ªto simulate the plastic deformation behavior in extrusion processes of heat sink for CPU. The relationships between the loading, strain, velocity distribution, and formability of the extruded product as well as the extrusion conditions are discussed. Furthermore, this research will propose a criterion for the die design of heat sink and to prove the validity of this proposed criterion by the experiments.
