An analysis of the extrusion process of the straight-fin heat sink in a computer

Abstract

In this paper, the finite element method is used to investigate the extrusion process of the straight-fin heat sink in computers. A series of simulations on the straight-fin extrusion using the program DEFORM 2D was carried out. The influences of the process parameters such as straight-fin thickness, straight-fin clearance and friction factor between the die and workpiece on the difference of maximum and minimum extruded fin lengths are examined.
