Abstract
A heat dissipation device includes a base (14) for absorbing heat from an electronic device and a plurality of fins (20) arranged on the base. A heat pipe (32) thermally contacts the fins and the base for transferring heat from the base to the fins. The heat pipe includes a U-shaped section thermally mounted below the base for absorbing the heat from the electronic device, two straight sections thermally engaging with the fins, and two arced sections interconnecting the U-shaped section and corresponding straight sections. The heat pipe is integrally formed by bending a straight heat pipe and functions as two U-shaped, individual heat pipes.

A heat dissipation device for removing heat from a heat generating electronic device, the heat dissipation device comprising:
- a base for absorbing heat from the electronic device;
- a plurality of fins arranged on a top face of the base;
- and
- a heat pipe thermally contacting the fins and the base for transferring heat from the heat generating electronic device to the fins, the heat pipe comprising two parallel evaporating sections connecting with each other and contacting thermally with a bottom face of the base, two parallel condensing sections located above the evaporating sections and extending through the fins, and two adiabatic portions interconnecting the evaporating sections and corresponding condensing sections.
A heat dissipation device comprising:
- a heat absorbing plate for thermally engaging with a heat generating electronic device;
- a base thermally attached on a top face of heat absorbing plate;
- a plurality of fins arranged on a top face of the base;
- and
- a heat pipe having two straight sections extending through the fins, a substantially U-shaped section thermally sandwiched between the base and the heat absorbing plate, and two arced sections interconnecting two ends of the U-shaped section with the straight sections.
