Abstract: A heat dissipation device includes a fin set, first and second base plates and first and second heat pipes. The first base plate has a face for contacting to a heat generating electronic device. The first heat pipe includes first and second sections sandwiching the fin set therebetween and thermally engaging with the fin set. The first and second base plates sandwich the first heat pipe and the fin set therebetween and thermally engaging with the first heat pipe and the fin set. The second heat pipe includes first and second sections sandwiching the first heat pipe, the fin set, the first and second base plates therebetween and thermally engaging with the first and second base plates.

Abstract: A heat dissipation device includes a heat sink (10) and a heat pipe (20). The heat sink includes a base (12), a fins group (16) extending from the base, and a cover (14) contacting with the fins group. The heat pipe surrounds top and bottom and two opposite sides of the fins group and thermally connects with the base and the cover.

Abstract: A heat dissipation device includes a heat sink (10) and at least a serpent heat pipe (22). The heat sink (10) comprises a base (12) contacting with an electrical component, a heat dissipation fins group (14) secured to the base (12) and a cover (16) attached to a top of the heat dissipation fins group (14). The heat dissipating fins group (14) defines a notch (148) at one side thereof. Two end portions of the heat pipe (22) are respectively connected to the base (12) and the cover (16), and a middle portion of the heat pipe (22) is accommodated in the notch (148).

Abstract: A heat dissipating device incorporating heat pipes includes a heat sink (10), a first heat pipe (50) and a second heat pipe (70). The heat sink has a first base (11), a second base (21) and a plurality of fins sandwiched between the first and second bases. Each of the heat pipes has a heat-absorption end (51, 71) and a heat-dissipation end (52, 72). The heat-absorption ends of the first and second heat pipes contact the first base of the heat sink. The heat-dissipation end of the first heat pipe is inserted in the substantial middle portion of the fins, and the heat-dissipation end of the second heat pipe is inserted between the second base and the fins.
