Abstract:
1. A heat sink for use with a heat generating device, comprising: a base member; a fixed set of at least three adjacent heat dissipating surfaces formed in said base member for causing said heat sink to have a predetermined low power dissipation level that is a function of the number of heat dissipating surfaces in said fixed set, each said heat dissipating surface being perpendicular to said base member; at least one groove formed in said base member between each two adjacent heat dissipating surfaces in said fixed set for enabling an additional individual heat dissipating surface to be securedly attached perpendicular to said base member in each said groove for enabling said heat sink to have a plurality of power dissipation levels that are in excess of said predetermined low power dissipation level as a function of the number of additional individual heat dissipating surfaces attached to said base member; and at least one additional individual heat dissipating surface attached perpendicular to said base member in one said groove for causing said heat sink to have a plurality of power dissipation levels that are in excess of said predetermined low power dissipation level as a function of the number of additional individual heat dissipating surfaces attached to said base member.
