Claim Text:
1. A heat dissipating device comprising: a heat dissipating fin module made of a first heat conducting material, the heat dissipating fin module comprising a first base and a plurality of first heat dissipating fins, the first heat dissipating fins extending from a side of the first base; a second base made of the first heat conducting material, a recess being formed on the second base; a third base made of a second heat conducting material, the third base being disposed in the recess, a surface of the third base being exposed, a thermal conductivity of the second heat conducting material being greater than a thermal conductivity of the first heat conducting material; a heat pipe comprising a heat dissipating segment, a heat absorbing segment and a connecting segment, the connecting segment connecting the heat dissipating segment and the heat absorbing segment, the heat dissipating segment being disposed in the first base, the heat absorbing segment being disposed in the second base and the third base, the heat absorbing segment contacting the third base directly; a first sleeve made of the first heat conducting material, the first sleeve at least covering the connecting segment; and a fourth base formed by the first heat conducting material, which is melted, in a die casting process and covering peripheries of the first and second bases and the first sleeve.
