Patent ID: 8072755

Claim:
An active heat-dissipating mechanism for use in an electronic device, said heat-dissipating mechanism comprising: a fan module comprising an airflow inlet and an airflow outlet; an airflow-guiding part disposed at the same side of said airflow outlet of said fan module and in communication with said fan module, wherein an airflow channel is defined by said airflow-guiding part, and an airflow inhaled by said fan module is guided to a hotspot region of said electronic device through said airflow channel so as to remove the heat generated from said hotspot region; and an airflow shunt part formed on said airflow-guiding part, wherein said airflow shunt part defines a stopping block in said airflow channel, and a portion of said airflow is hindered by said stopping block and guided into a sub-hotspot region of said electronic device so as to remove the heat generated from said sub-hotspot region.
