Patent ID: 8294340

Claim:
A heat dissipation device comprising: a heat absorption board adapted for contacting a light source to absorb heat therefrom; a fin assembly located over the heat absorption board; two spaced heat pipes each comprising an evaporator section and two condenser sections extending from two opposite ends of the evaporator section, the condenser sections extending through the fin assembly; and a heat sink located between the heat absorption board and the fin assembly, the evaporator sections of the heat pipes being sandwiched between the heat sink and the heat absorption board, the heat sink comprising a pair of first heat dissipating branches and a pair of second heat dissipating branches extending outwardly from a central portion thereof, the first heat dissipating branches and the second heat dissipating branches being alternate with each other, the first heat dissipating branches contacting the evaporator sections of the heat pipes, the second heat dissipating branches being located between the heat pipes.
