Abstract
A fan duct assembly (10) includes a fan duct (20) and a fan (30). The fan duct is connected between a heat sink (50) and a computer casing (40). The heat sink is mounted on a heat-generating electronic device (60) accommodated in the computer casing. The fan duct is made of hard plastic material, and can therefore maintain its shape. The fan duct includes first and second flues (22, 24) oriented substantially perpendicular to each other. The fan is secured in the duct at a junction of the first and second flues. Thus, the fan duct assembly provides a passageway for air to travel between the heat sink and an exterior of the computer casing.
