Abstract:
1. A heat sink apparatus for dissipating heat generated from a heat generating component attached to a top surface of a circuit board, the heat sink apparatus comprising: a first heat dissipating assembly attached to the heat generating component; a second heat dissipating assembly attached to a bottom surface of the circuit board; and a connecting device thermally connecting the first heat dissipating assembly to the second heat dissipating assembly, thereby forming a continuous heat dissipation passage between the first heat dissipating assembly and the second heat dissipating assembly; wherein the connecting device comprises a first connecting panel connected to the first heat dissipating assembly and a second connecting panel connected to the second heat dissipating assembly, the first connecting panel and the second connecting panel are attached to opposite sides of the circuit board and thermally connected to each other.
