Abstract
An exemplary electronic device includes a cover, a motherboard and a driving module both disposed at an inner side of the cover, an electronic component fixed on the motherboard, and a fan duct mounted on the motherboard and covering the electronic component. The driving module has a rotating shaft for supportively driving an optical disk rotating. The fan duct guides hot air therein toward the driving module.
Claims20
An electronic device comprising:
- a motherboard;
- a driving module comprising a rotating shaft adapted for supportively driving an optical disk to rotate;
- an electronic component mounted on the motherboard and generating heat during operation;
- and
- a fan duct mounted on the motherboard and covering the electronic component, the fan duct guiding hot air therein toward the driving module.

5 more elements
An electronic device comprising:
- a bottom cover defining a plurality of ventilation holes therein;
- a motherboard and a driving module both positioned in an inner side of the bottom cover, the driving module having a rotating shaft adapted for driving an optical disk to rotate;
- a top cover covering the bottom cover, the motherboard and the driving module, a circular concave portion adapted for receiving the optical disk being inwardly formed from the top cover, a plurality of through holes being defined in the circular concave portion, and an airflow pipe being defined in the top cover to communicate with an outer side of the top cover and the through holes of the circular concave portion;
- an electronic component fixed on the motherboard and generating heat during operation;
- and
- a fan duct mounted on the motherboard and covering the electronic component, one end of the fan duct communicating with the through holes of the circular concave portion, and another end of the fan duct communicating with the ventilation holes of the bottom cover;
- wherein air heated by the electronic component in the fan duct can flow out of the top cover via the through holes and the airflow pipe, and rotation of the optical disk facilitates such airflow.
