Title: Heat dissipation device with parallel and perpendicular fins

Abstract: A heat dissipation device includes a heat pipe, a first fin unit, a second fin unit, and a centrifugal fan arranged on the first fin unit for drawing air from the first fin unit to the second fin unit. The heat pipe includes an evaporation section, a first condensing section and a second condensing section. The first fin unit includes a plurality of stacked first fins with a first channel defined between adjacent first fins. A notch is defined in the first fin unit receiving the evaporation section, and a canal is defined in the first fin unit receiving the first condensing section of the heat pipe. The second channel includes a plurality of stacked second fins. A second channel is defined between adjacent second fins perpendicular to the first channels. A passage is defined in the second fin unit receiving the second condensing section of the heat pipe.
