Abstract
The present heat dissipation device is provided with a fan frame and a blade structure. The fan frame includes an air inlet, an air outlet, and a curved portion. The air inlet has a non-circular indentation in the vicinity of the curved portion corresponding to the airflow passage. This indentation effectively increases the airflow amount and static pressure of the airflow expelled from the heat dissipation device.
