HEAT DISSIPATION APPARATUS FOR EXPANSION BASE

摘要

A heat dissipation apparatus includes an expansion base, a fan, an air duct, and a portable device. A number of air inlet slots and an inserting slot are defined in the expansion base. The air duct and the portable device are inserted in the inserting slot. A first air inlet opening and a first air outlet opening are defined in the air duct. An airflow passage is defined between the air inlet slot, the fan, the first air inlet opening, the air duct, the first air outlet opening, and the portable device. The fan is adapted to generate airflow through the portable device in such a manner that airflow flows from the expansion base outside is sucked into and blown out of the portable device via the airflow passage.
