Abstract:
1. A heat-dispersing module of an electronic device, comprising: a housing having a top surface, a bottom surface, a first side surface and a second side surface, wherein said first side surface is opposite to said second side surface; a heat-dispersing fan mounted on said first side surface of said housing; a first vent area disposed on said second side surface of said housing; a second vent area disposed on said top surface of said housing; and a printed circuit board positioned in said housing, thereby a first airflow channel is formed between said top surface of said housing and said printed circuit board, and a second airflow channel is formed between said bottom surface of said housing and said printed circuit board, wherein said printed circuit board produces a relatively higher heat at said second airflow channel than said first airflow channel and a distance of said second airflow channel from said printed circuit board to said bottom surface is relatively larger than that of said first airflow channel from said printed circuit board to said top surface, wherein said second airflow channel has a first airflow passing through said first vent area, said first airflow channel has a second airflow passing through said second vent area, and said first airflow and said second airflow are separated by said printed circuit board so that the first airflow is not influenced by the second airflow.
