ABSTRACT:
A heat dissipation device includes a heat sink (10) and a first heat pipe (20) enclosing a bottom edge of the heat sink. The heat sink includes a base (12) defining a first passage (120) extending therethrough. The first heat pipe includes a first transferring section (22) extending in the first passage and totally embedded in the base and a pair of first dissipating sections (24) extending from the first transferring section. The first dissipating sections of the first heat pipe are attached on an outer periphery of the base. The first transferring section of the first heat pipe absorbs heat in the middle of the base and transfers it to the first dissipating sections to evenly distribute the heat throughout the whole base.
