Abstract:
1. A heat dissipation device adapted for dissipating heat from a heat-generating device, comprising: a heat pipe assembly for absorbing heat from the heat-generating device, the heat pipe assembly comprising at least two pairs of bendable heat pipes each having a top face and a bottom face; and a fin set thermally engaged with the heat pipe assembly, the fin set comprising a plurality of fins and having a bottom surface; wherein the at least two pairs of heat pipes of the heat pipe assembly are juxtaposed with each other, the top faces of the at least two pairs of heat pipes are thermally attached to the bottom surface of the fin set, and the bottom faces of the at least two pairs of heat pipes are level with each other to form a contacting surface for contacting the heat generating device; wherein the at least two pairs of heat pipes are flat oval shaped in a cross section of the heat pipe assembly; wherein the at least two pairs of heat pipes are arranged on the bottom surface of the fin set symmetrically relative to a central axis of the fin set; wherein each pair of the at least two pairs of heat pipes are oriented opposite to each other, and elongated sections of the each pair of the at least two pairs of heat pipes abut against one another; and wherein the bottom surface of the fin set has two protruding strips extending downwardly, and the two protruding strips each are encircled by a corresponding pair of heat pipes.
