ABSTRACT:
An electronic device includes a base, a motherboard having an electronic component, a fan unit, and an airflow guiding cover. The airflow cover includes a top panel and two side panels. An air channel is bounded by the top panel and the side panels. The electronic component is received in the air channel. The air channel includes opposite open ends. The fan unit aligns with one of the open ends of the air channel, to draw airflow in the air channel out. The top panel defines a plurality of through holes adjacent to the fan unit, to discharge a part of the airflow in the air channel out of the airflow guiding cover, for reducing change of the pressure gradient of the airflow, thereby reducing aerodynamic noise.
