Patent ID: 7779897

Claim:
A heat dissipation device adapted for dissipating heat from a heat-generating device, comprising: a heat-absorbing plate for absorbing heat from the heat-generating device; a U-shaped heat pipe assembly thermally attached on the heat-absorbing plate, the U-shaped heat pipe assembly comprising a plurality of bent heat pipes each having an evaporating section and a condensing section extending from an end of the evaporating section; and a fin set thermally defining a contacting surface attached to the heat pipe assembly; wherein the evaporating sections of the U-shaped heat pipe assembly are covered by the heat-absorbing plate and the condensing sections of the U-shaped heat pipe assembly are exposed outside of the heat-absorbing plate the U-shaped heat pipe assembly and the heat absorbing plate, each being arranged on a same plane parallel to each other, and wherein the evaporating sections of the heat pipe directly contact the heat-absorbing plate, whereby the heat absorbed by the heat pipes from the heat-absorbing plate is directly transferred to the fin set.
