Abstract
An exemplary fan duct includes a top plate, two sidewalls and a baffle. The sidewalls extend from opposite ends of the top plate. The baffle engages with the top plate and is located between the two sidewalls. The baffle includes a first end and a second end opposite to the first end, the first end pivotably engages with the top plate, and the baffle rotates about the first end to make the second end engage with the top plate or one of the sidewalls.
Claims20
A fan duct comprising:
- a top plate;
- two sidewalls depending from opposite sides of the top plate;
- and
- a baffle between the two sidewalls, the baffle pivotally engaged with the top plate;
- wherein the baffle comprises a first end and a second end opposite to the first end, the first end is pivotally engaged with the top plate, and the baffle is rotatable about the first end to make the second end selectively engage with the top plate or either one of the sidewalls;
- an extending plate extends from the top plate and is located between the two sidewalls, and opposite sides of the first end of the baffle pivotally engage with the top plate and the extending plate, respectively;
- and
- a tube protrudes from the extending plate, two first pins are formed on opposite ends of the first end of the baffle, one of the first pins extends through the top plate and the other first pin is received in the tube, and the baffle rotates about the two first pins.

An electronic device comprising:
- a casing;
- a printed circuit board (PCB) enclosed by the casing;
- and
- a fan duct mounted on the PCB, the fan duct comprising:
- a top plate;
- two sidewalls depending from opposite sides of the top plate;
- and
- a baffle located between the two sidewalls, the baffle comprising a first end and a second end opposite to the first end, the first end pivotally engaging with the top plate;
- wherein when two electronic components are mounted on the PCB and are located in line between the sidewalls of the fan duct, the second end of the baffle is engaged with the top plate to position the baffle between the two electronic components with the baffle being aligned along a direction of airflow, such that air flowing through the fan duct is not baffled by the baffle and passes over the two electronic components;
- and
- when only one of the two electronic components is mounted on the PCB, the second end of the baffle is engaged with the sidewall away from the electronic component, such that the baffle baffles air flowing through the fan duct at the location of the missing electronic component and directs at least part of such air to flow toward the electronic component mounted on the PCB.

A fan duct comprising:
- a top plate;
- first and second sidewalls depending from opposite sides of the top plate;
- a flexible baffle between the two sidewalls, the baffle pivotably engaged with the top plate;
- and
- an extending plate extending from the top plate and located between the first sidewall and the second sidewall;
- wherein the baffle comprises opposite first and second ends, the first end is pivotably engaged with the top plate, and the baffle is pivotable about the first end to cause the second end to be selectably engaged with any one of the top plate, the first sidewall, and the second sidewall;
- an air channel is defined between the first sidewall and the extending plate, another air channel is defined between the second sidewall and the extending plate, and the two air channels are located side by side and aligned with each other along a transverse direction of the top plate;
- when the second end of the baffle engages with the top plate, the baffle is aligned with the extending plate along a longitudinal direction of the top plate to allow air to flow through the two air channels of the fan duct and not be baffled by the baffle;
- and
- when the second end of the baffle engages with the first sidewall or the second sidewall, the baffle is angled with respect to the extending plate to baffle air flowing in one of the air channels and direct at least some of the baffled airflow toward the other air channel.
