Patent ID: 8270166

Claim:
A heat dissipation device for cooling a first electronic component and a second electronic component simultaneously wherein the first electronic component generates more heat than the second electronic component during operation, the heat dissipation device comprising: a centrifugal fan defining a first air outlet and a second air outlet in lateral sides thereof; a first fin assembly disposed at the first outlet of the centrifugal fan; a second fin assembly disposed at the second outlet of the centrifugal fan and thermally contacting the second electronic component, the first fin assembly and the second fin assembly being made of different thermally conductive materials, and the thermal conductivity of the first fin assembly being greater than that of the second fin assembly; and a heat pipe comprising an evaporating section at a middle thereof, and a first condensing section and a second condensing section located at two opposite ends of the evaporating section, the evaporating section thermally contacting the first electronic component, the first condensing section being thermally attached to the second fin assembly, and the second condensing section being thermally attached to the first fin assembly.
