Abstract
A heat sink. The heat sink includes spaced laminas made of a thermally conductive material. Each of the laminas is integrally formed with a pair of convexo-concave spacers that each project from a first face of the lamina and define a cavity in a second face of the same lamina. Furthermore, each of the convexo-concave spacers is adapted to be partially and tightly fitted in a mating cavity of the next lamina.
Claims6
A heat sink comprising:
- a plurality of spaced laminas made of a thermally conductive material, each of said laminas being integrally formed with at least one convexo-concave spacer having a tapered configuration projecting from a first face of said lamina and defining a cavity in a second face of said lamina, and said convexo-concave spacer being adapted to be partially and tightly fitted in a mating cavity of the next lamina;
- wherein each of said laminas has an opening for receiving a heat conductor, and a vent array for additional heat dissipation;
- and
- wherein each of said laminas further comprises a collar surrounding said opening and in contact with said heat conductor.
