Heat dissipation device with high efficiency |
摘要 |
The heat dissipation device includes a frame and an impeller. The frame has an inlet and an outlet, in which the inlet has a noncircular shape. The inlet can be provided with a blocking board so as to be noncircular. The blocking board suppresses airflow dissipated from a high pressure region of the airflow path in order to enhance outgoing airflow.
