Abstract
A heat dissipation apparatus includes an expansion base, an air duct, a fan, a heat sink, and a portable device. A number of air inlet slots is defined in the expansion base. A first air inlet opening and a number of diagonal air outlet slots are defined in the air duct. A third air inlet opening and a third air outlet opening are defined in the portable device. The fan generates 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 air duct via a first airflow passage. The portable device guides airflow in and out of the portable device via a second airflow passage.
Claims16
A heat dissipation apparatus, comprising:
- an expansion base comprising a base body, an air inlet slot defined at one side of the base body;
- a first inserting slot and a second inserting slot defined at a top of the base body;
- an air duct inserted in the first inserting slot, the air duct comprising a duct body, a first air inlet opening defined at a bottom of the duct body, a plurality of air outlet slots defined diagonally across a top of the duct body;
- a fan fixed in the duct body;
- and
- a portable device configured to be inserted in the second inserting slot, a third air inlet opening and a third air outlet opening defined in the portable device, a first heat dissipation element and a second heat dissipation element mounted on the portable device, and a heat sink mounted on the first heat dissipation element and the second heat dissipation element;
- wherein a first airflow passage is defined between the air inlet slot, the fan, the first air inlet opening, the air duct, and the plurality of air outlet slots;
- the fan is adapted to generate airflow through the portable device so that airflow flows from the expansion base outside is sucked into and blown out of the air duct via the first airflow passage;
- a second airflow passage is defined between the third air inlet opening, the heat sink, and the third air outlet opening;
- the portable device is configured to guide airflow in and out of the portable device via the second airflow passage.
