Abstract
A charger may include: a casing including an air inlet and an air outlet; an inner wall extending from an inner surface of the casing and defining an accommodating space between the inner surface of the casing and the inner wall; and a centrifugal fan including an air feed port and disposed in the accommodating space. The air outlet may be disposed to face the air feed port. The air inlet may be disposed closer to the centrifugal fan than the inner wall is. In a direction of a rotation axis of the centrifugal fan, a width between the inner wall and the centrifugal fan may be less than or equal to 150% of a width of the centrifugal fan.
