ABSTRACT:
A heat dissipation device includes a first base plate (10), a fin group (30) arranged on the first base plate, a first heat pipe (50) attached on the first base plate and the fin group and a second heat pipe (60) attached on the first base plate and extending across the fin group. Each of the first and second heat pipes includes an absorbing section and a dissipating section. The absorbing sections of the first and second heat pipes are L-shaped and oriented in opposite directions and dissipating sections of the first and second heat pipes are oriented perpendicular to each other, whereby heat from the first base plate attached with an electronic component can take more different dissipating-paths from the first base plate to the fin group.
