1. A heat dissipation system suitable for a portable electronic device, wherein the portable electronic device has two heat sources, and the heat dissipation system comprises:
a centrifugal fan, having a main outlet and a sub outlet;
two heat dissipation fin sets disposed respectively at the main outlet and the sub outlet;
a gate disposed at the sub outlet;
a first heat pipe thermally contacting the two heat sources, and thermally contacting the heat dissipation fin set located at the main outlet;
a second heat pipe thermally contacting one of the two heat sources, and thermally contacting the two heat dissipation fin sets; and
a control unit electrically connected to the gate, wherein the control unit drives the gate to open or close the sub outlet according to a load of the two heat sources.
