Abstract
A heat dissipation system suitable for a portable electronic device with two heat sources includes a centrifugal fan, two heat dissipation fin sets, a gate, a first heat pipe, a second heat pipe, and a control unit. The centrifugal fan has a main outlet and a sub outlet. The heat dissipation fin sets are disposed respectively at the main outlet and the sub outlet, and the gate is disposed at the sub outlet. The first heat pipe thermally contacts the heat sources and the heat dissipation fin set located at the main outlet. The second heat pipe thermally contacts one of the heat sources and the two heat dissipation fin sets. The control unit is electrically connected to the gate to drive the gate to open or close the sub outlet based on a load of the two heat sources.
