Abstract:
1. A computer system comprising: a chassis comprising a chassis bottom wall, a chassis front wall and a chassis rear wall; the chassis front wall defining a first ventilation hole, and the chassis rear wall defining a second ventilation hole; a motherboard secured to the chassis bottom wall between the chassis front wall and the chassis rear wall; a memory card secured to the motherboard; a power supply bracket secured to the rear wall; and a locking component located in the chassis and perpendicular to the chassis bottom wall, and a locking hole defined in the locking component; and an airflow guiding duct secured in the chassis, the airflow guiding duct comprising an entrance portion and a duct sidewall connected to the entrance portion; a retaining portion connected to the duct sidewall, being engaged in the locking hole; the entrance portion covering a portion of the memory card, and the duct sidewall substantially covering a space between the locking component and the power supply bracket, so as to guide airflow; wherein the airflow is configured to flow in the chassis via the first ventilation hole, over the memory card, and then out of the chassis via the second ventilation hole; wherein the power supply bracket is in communication with an outside of the chassis via the second ventilation hole, to enable the airflow to flow out of the chassis; a drive bracket is configured for receiving disk drives and secured on the chassis front wall, the locking component is perpendicularly connected to a wall of the drive bracket; and the airflow guiding duct, and the drive bracket and the power supply bracket together define a space for the airflow flowing from the memory card to the second ventilation hole.
