Abstract
An air guiding duct and casing providing easy access for fan maintenance and electronic devices using the air guiding duct are disclosed. The air guiding duct includes a first guiding plate and a second guiding plate. The first guiding plate includes a first pivoting portion and first extension panels. The second guiding plate includes a second pivoting portion and second extension panels. The first guiding plate is rotatably connected to the second guiding plate, and can be in a first position to align with the second guiding plate and join each first extension panel with a second extension panel, to define air guiding channels for heat dissipation, and a second position, where the first guiding plate is tilted with a predetermined angle relative to the second guiding plate.
