The coil portion is disposed between the hollow portion and the housing portion. The heatsinks are respectively disposed on different sidewalls. The heat-dissipation device comprises a wind-guiding cover and a first fan. The wind-guiding cover comprises a wind-guiding main board and wind-guiding lateral boards. The wind-guiding main board is disposed adjacent to the second surface. The wind-guiding lateral boards are vertically extended from different lateral edges of the wind-guiding main board towards the same direction. Each wind-guiding lateral board is disposed corresponding to one of the heatsinks, and at least one of the wind-guiding lateral boards has a hole. The first fan is received by the hole.
