A container of a cloud computing system includes a housing defining a chamber, an airflow inlet and an airflow outlet, a fan fixed in the airflow inlet, and a dust gauze covering the airflow inlet. The airflow inlet and the airflow outlet both communicate with the chamber. The fan is capable of rotating clockwise or counter-clockwise by a controlling device. During the fan rotates clockwise, the fan draws exterior air into the chamber through the airflow inlet, and then air vents out of the chamber via the airflow outlet. During the fan rotates counter-clockwise, the fan draws the air in the chamber blow to the dust gauze via the airflow inlet to clear dust on the dust gauze.
