1. An electronic device, comprising:
a body, comprising a through opening, and an outer surface and an inner surface opposite to each other, wherein the through opening passes through the outer surface and the inner surface;
a fan, disposed on the outer surface of the body, the fan having an air outlet;
a heat sink assembly, disposed at the air outlet and corresponding to the through opening, wherein:
the heat sink assembly comprises a plurality of cooling fins, an upper plate, and a lower plate,
each of the plurality of cooling fins has a first side, a second side, a third side, and a fourth side,
the first side and the second side are parallel and opposite to each other,
the third side and the fourth side are parallel and opposite to each other,
the third side and the fourth side are respectively connected between the first side and the second side,
the first side is adjacent to the fan,
the upper plate is perpendicular to the plurality of cooling fins and is disposed on the third side,
the lower plate is perpendicular to the plurality of cooling fins and is disposed on the fourth side,
the fourth side comprises a first section, a second section, and a third section,
the first section is perpendicularly connected to the first side,
the third section is perpendicularly connected to the second side,
the second section is perpendicularly connected to the first section and the third section, and
a position of the first section corresponds to a position of the through opening;
a first thermal tube, having one end thereof assembled on the heat sink assembly, and located on a side of the outer surface;
a first heat source, disposed at a position corresponding to a second end of the first thermal tube;
a thermal plate, disposed in the body and corresponding to the through opening, one side of the thermal plate abutting against the heat sink assembly and the inner surface;
a second thermal tube, having one end thereof connected to a second side of the thermal plate such that the first thermal tube is separated from the second thermal tube by the heat sink assembly and the thermal plate that are disposed between the first thermal tube and the second thermal tube; and
a second heat source, disposed at a position corresponding to a second end of the second thermal tube.
