Abstract:
1. A cooling device, comprising: a chassis that partitions a first space, a second space, and a third space sandwiched between the first space and the second space; a printed circuit board accommodated in the chassis that extends from the first space to the second space while traversing the third space; a fan occupying the third space outside a predetermined space that produces an air flow from the first space toward the second space by rotation of a rotor blade, wherein the predetermined space is ensured between the printed circuit board and the fan in the third space; and an air duct member that occupies the predetermined space to form a flow passage of the air flow from an intake port to an exhaust port on the printed circuit board, wherein the intake port is opened to the second space and the exhaust port is opened to the first space.
