An optical disk drive is provided. The optical disk drive includes a housing, a chassis and an elastic dust-proof slice. The housing includes a top plate and a bottom plate. The chassis, which is deposited inside the housing, includes a lateral plate wherein the lateral plate has an airflow exit for dissipating heat. The elastic dust-proof slice is swimmingly deposited on the lateral plate for closing or opening the airflow exit. In natural situation, the elastic dust-proof slice is located on a shielding position and closes the airflow exit. When a hot airflow generated inside the optical disk drive flows to the airflow exit, the elastic dust-proof slice is pushed by the hot airflow and swung away from the outside surface of the lateral plate. As a result, the airflow exit is opened and the hot airflow flows out of the chassis via the opened airflow exit.
