Patent ID: 8749975

Claim:
A computer system, comprising: an enclosure comprising a bottom plate, a mounting panel and a separating plate each extending from the bottom plate; a printed circuit board mounted on the bottom plate and substantially parallel to the bottom plate, the printed circuit board comprising a first heat generating element and a second heat generating element; and an airflow guiding duct comprising a top wall, a first sidewall, a second sidewall, a first mounting wall extending from the first sidewall, and a second mounting wall extending from the second sidewall, wherein the first sidewall, the second sidewall, the first mounting wall, and the second mounting wall are connected to the top wall; an input opening is surrounded by the top wall, the first sidewall, and the second sidewall; a first output opening is defined by the top wall, the first mounting wall, and the second mounting wall, the first output opening corresponds to the first heat generating element; the first heat generating element is located between the first mounting wall and the second mounting wall; a second output opening is defined in the second sidewall corresponding to the second heat generating element; an obtuse angle is defined between the second sidewall and the second mounting wall, wherein the airflow guiding duct is removeably coupled to each of the bottom plate, the mounting panel, and the separating plate.
