Patent attributes
A heat dissipation device includes a first heat sink (10), a second heat sink (20) and four heat pipes (30) thermally connecting the first heat sink and second heat sink. The first heat sink comprises a plurality of first heat dissipation fins (14) and the second heat sink comprises a plurality of second heat dissipation fins (24). Each heat pipe comprises an evaporating portion (32) and a condensing portion (34). The evaporating portions of two heat pipes thermally engage in a base of the first heat sink and the condensing portions thereof connect the first and second heat dissipation fins. The evaporating portions of the other two heat pipes thermally engage in a base of the second heat sink and the condensing portions thereof connect the second and first heat dissipation fins.
