Abstract
A heat dissipating apparatus includes a heat sink, a first air moving device coupled to a first end of the heat sink, and a second air moving device coupled to a second end of the heat sink. The first air moving device drives an airflow to move through the heat sink in a direction and the second air moving device drives the airflow to move through the heat sink in the direction.
Claims21
