Patent ID: 7295437

Claim:
A heat dissipation device comprising: a first heat sink adapted for receiving heat from a first heat-generating electronic component, comprising a plurality of first heat dissipation fins; a second heat sink adapted for receiving heat from a second heat-generating electronic component, comprising a plurality of second heat dissipation fins; and at least two heat pipes, each heat pipe comprising an evaporating portion and a condensing portion; wherein the evaporating portion of one of the at least two heat pipes contacts with a first base of the first heat sink, the condensing portion of the one of the at least two heat pipes connecting the first heat sink and the second heat sink, and the evaporating portion of the other of the at least two heat pipes contacts with a second base of the second heat sink, the condensing portion of the other of the at least two heat pipes connecting the second heat sink and the first heat sink; wherein each of the at least two heat pipes further comprises a connecting portion between the evaporating portion and the condensing portion and the connecting portions of the at last two heat pipes are located at two opposite outer sides of the first and second heat sinks; wherein the evaporating portion and the condensing portion of each of the at least two heat pipes are located at two opposite ends of each of the at least two heat pipes and the condensing portion of each of the at least two heat pipes extends through the first and second heat sinks; and wherein the at least two heat pipes are substantially J-shaped and each of them comprises a first horizontal portion and a second horizontal portion, the first horizontal portions respectively connecting with the first and second bases, the second horizontal portions extending through the first and second heat dissipation fins.
