Abstract
An airflow-guiding device for guiding airflow to heat generating components includes an airflow-guiding shield and at least one airflow-guiding piece rotatable in the airflow-guiding shield. The airflow-guiding piece includes a guiding surface guiding airflow, and a blocking surface blocking airflow. An airflow-guiding position where the guiding surface faces the heat generating components guides airflow thereto, and an airflow-blocking position where the blocking surface faces the airflow blocks the airflow. The airflow-guiding piece rotates between the airflow-guiding position and the airflow-blocking position.
