20100315778AIRFLOW-ADJUSTABLE ACTIVE HEAT-DISSIPATING MECHANISM AND ELECTRONIC DEVICE HAVING SAME - An active heat-dissipating mechanism includes a fan module, an airflow-guiding part and an airflow shunt part. The fan module includes an airflow inlet and an airflow outlet. The airflow-guiding part is disposed at the same side of the airflow outlet of the fan module and in communication with the fan module. An airflow channel is defined by the airflow-guiding part. An airflow inhaled by the fan module is guided to a hotspot region of the electronic device through the airflow channel so as to remove the heat generated from the hotspot region. The airflow shunt part is formed on the airflow-guiding part. The airflow shunt part defines a stopping block in the airflow channel. A portion of the airflow is hindered by the stopping block and guided into a sub-hotspot region of the electronic device so as to remove the heat generated from the sub-hotspot region.12-16-2010
