Patent ID: 8052282

Claim:
An electronic device, comprising: a heat dissipation system comprising: a housing; a heat dissipation module received in the housing; and heat pipes extending from the heat dissipation module through the housing; and an operating system comprising: a dust-proof housing; a heat source received in the dust-proof housing and capable of generating heat; and a cooling module adhered to an outer surface of the dust-proof housing to be cooled; wherein the heat pipes are attached to the cooling module and are capable of transferring heat from the operating system into the heat dissipation module, an airflow channel is defined in the dust-proof housing, the airflow channel surrounds the heat source and configured to allow air to circulate therein to dissipate heat inside the dust-proof housing to sidewalls of the dust-proof housing, the dust-proof housing is configured to prevent the air circulating in the airflow channel from exhausting from the airflow channel, the dust-proof housing is also configured to prevent exterior air from flowing into the airflow channel.
