ABSTRACT:
A method of manufacturing a high fin density heat dissipator is disclosed in which the dissipator is extruded through a die in a partially cylindrical shape with the elongated fins arranged on the base and extending radially therefrom. The extruded dissipator is straightened under tensile and bumping forces in a manner such that the base assumes a planar shape and the fins become substantially parallel to each other. Apparatus for straightening the extruded dissipator and a die for extruding the same are illustrated and described.
