1. A heat sink, comprising
a heat sink body having a plurality of stacked fins; and
a mounting base including a first heat dissipation plate, a first surface of the first heat dissipation plate connected to a bottom of the heat sink body, and a second heat dissipation plate, discrete from the first heat dissipation plate, mounted on a second surface of the first heat dissipation plate opposite to the first surface, a length of the second heat dissipation plate in a longitudinal direction of the heat sink body is less than a length of the first heat dissipation plate in the longitudinal direction and a width of the second heat dissipation plate is less than a width of the first heat dissipation plate, the heat sink body including the plurality of stacked fins having a length in the longitudinal direction greater than the length of the first heat dissipation plate in the longitudinal direction, each fin of the plurality of stacked fins extending perpendicularly from a top of the first heat dissipation plate, a lower edge of each of the stacked fins having at least one tab extending downwardly therefrom, the tabs of the fins arranged in a row and forming a protrusion extending in a lateral direction and fixed to the first heat dissipation plate.
