Electronic device with air guiding apparatus
An electronic device includes a chassis and an air guiding apparatus. The chassis includes a bottom wall, a first sidewall, a second sidewall, a first end wall, a second end wall, a circuit board mounted on the bottom wall, and a fan. The air guiding apparatus includes a flexible air guiding piece. The first and second end walls each define a number of vents. A chip is mounted on the circuit board. The fan is installed in the chassis adjacent to the vents of the second end wall. The air guiding apparatus is fixed to the first end wall. A first end of the air guiding piece is stretchable to be fixed to the second end wall. The air guiding piece, the first sidewall, the first end wall, and the second end wall cooperatively bound an airflow channel for receiving the fan and the chip.
