Abstract
A heat dissipation assembly is configured in an enclosure of a network device. The enclosure defines an air flue. The heat dissipating assembly includes a fan module received in the air flue, and a damper module secured in one end of the air flue adjacent to the inside of the enclosure. The fan module includes a first bracket and a plurality of fans fixed with the first bracket. The damper module includes a frame and a plurality of vanes located in the frame. When a direction of airflow of the plurality of fans changes, the plurality of fans in the air flue is reversed, and the first bracket supports the plurality of vanes of the damper module to keep the air flue open.
Claims19
A heat dissipation assembly configured in an enclosure of a network device, the enclosure defining an air flue running through an inside of the enclosure and an outside of the enclosure, the heat dissipating assembly comprising:
- a fan module received in the air flue, and comprising a first bracket and a plurality of fans fixed with the first bracket;
- and
- a damper module secured in a first end of the air flue facing the inside of the enclosure, and the damper module comprising a frame and a plurality of vanes located in the frame;
- wherein when airflow of the plurality of fans flows from the outside of the enclosure to the inside of the enclosure, the plurality of vanes of the damper module are lifted by a force of the airflow, and when an airflow of the plurality of fans flows from the inside of the enclosure to the outside of the enclosure, the plurality of fans in the air flue are in a reversed position;
- the first bracket supporting the plurality of vanes of the damper module to keep the air flue open.
A network device comprising an enclosure and a plurality of heat dissipation assemblies, the enclosure defining a plurality of air flues running through an inside of the enclosure and an outside of the enclosure, each of the plurality of heat dissipation assemblies corresponding to one of the plurality of the air flues, each heat dissipation assembly comprising:
- a fan module received in the corresponding air flue, and comprising a first bracket and a plurality of fans fixed with the first bracket;
- and
- a damper module secured in a first end of the corresponding air flue adjacent to the inside of the enclosure, and the damper module comprising a frame and a plurality of vanes located in the frame;
- wherein when airflow of the plurality of fans flows from the outside of the enclosure to the inside of the enclosure, the plurality of vanes of the damper module are lifted by a force of the airflow, when the airflow of the plurality of fans flows from the inside of the enclosure to the outside of the enclosure, the plurality of fans in the air flue are in reversed position with the first bracket supporting the plurality of vanes of the damper module to keep the air flue open.
