In order to produce, e.g., an improved heat sink, there is disclosed, in the most comprehensive aspect of the invention, a method of joining together a pair of members each having a high thermal conductivity, which method comprises the steps of: forming a first of the two thermally high conductivity members (1,2), at a joining surface thereof, with either of a plurality of projecting portions and a plurality of projecting and recessed portions; forming a second of the said two members, at a joining surface thereof, with either of a plurality of recessed portions each of which corresponds to a selected one of the said projecting portions and a plurality of projecting portions each of which corresponds to a selected one of the recessed portions of the said projecting and recessed portions of the said first member; and inserting under pressure each of the said projecting portions of one of the said two members (1,2) into each of the said recessed portions that corresponds thereto, of another of the said two thermally high conductivity members, with a tolerance that is sufficient to induce a plastic deformation in each of the said members. A variety of improved heat sinks prepared using the method described are also disclosed. <IMAGE> |
