Electronic device with heat dissipation structure

摘要

An electronic device includes a computer, a circuit board, a supporting base attached to a top surface of the circuit board, and a backboard attached to a bottom surface of the circuit board. The case includes a bottom plate. The circuit board defines a through hole. A CPU is located on the supporting base. The backboard defines a retaining hole. The supporting base defines a fixing hole. A heat sink is attached to the supporting base and contacted the CPU. A fixing member is engaged with the retaining hole, the fixing hole and the through hole, to engage the backboard and the supporting base to the circuit board.
