Method of manufacture of heat exchange unit

摘要

A heat exchange unit and the method of its manufacture including a base plate with heat dissipating protrusions extending therefrom which are formed by plastic deformation. One or more long holes extend through the base plate to receive heat pipes in conductive contact. The long hole is formed during the extrusion of billets from which the units are formed. Mandrels are placed in the long holes through the billets and the heat exchange unit is formed therefrom. The mandrel is then extracted and replaced by a heat pipe. Further deformation of the base plate around the inserted heat pipe can insure intimate contact for heat conduction between components.
