A method of forming a high fin density heatsink from a plurality of fins each having a bottom portion of generally bell-bottom shape and a base unit of predetermined thickness having a plurality of grooves therein. The method comprises the steps of placing the plurality of fins loosely in respective ones of the grooves, and applying downward and horizontal pressure to the base unit intermediate respective ones of the fins for swaging the base unit so as to urge the fins downwardly into the respective ones of the grooves thereby creating a solid connection between the base unit and the fins with excellent thermal contact therebetween.

La présente invention fait état d'une méthode de fabrication d'un dissipateur de chaleur à densité élevée d'ailettes. Le dissipateur est formé à partir de nombreuses ailettes dont la partie inférieure est généralement évasée et d'une unité de base à épaisseur préétablie comportant un certain nombre de rainures. Il suffit de placer les ailettes, sans les serrer, dans chacune des rainures et d'appliquer une force descendante et horizontale à l'unité de base entre chacune des ailettes pour emboutir l'unité de base et faire descendre les ailettes afin qu'elles pénètrent dans chacune des rainures. Il en résulte un lient solide et une excellente conductivité thermique entre les ailettes et l'unité de base.
