ABSTRACT:
A heat dissipation device includes a base (10), a plurality of fins (20), first and second heat pipes (30), (40), a fan holder (50) and a fan (60) secured to the fan holder. The first heat pipe includes a heat-receiving section (32) and two heat-discharging sections (34). The second heat pipe includes an evaporating portion (42) and two condensing portions (44). The condensing portions of the second heat pipe extend into the fins and are disposed adjacent to opposite ends of each of the fins. One heat-discharging section extends in the fins and is disposed between the condensing portions, thus allowing heat absorbed from the base to be evenly distributed throughout the fins by the heat-discharging sections and the condensing portions.
