1. A power supply apparatus comprising:
- an air path extending longitudinally;
a first wall in which an opening facing the air path is formed;
a fan that blows air, through the opening, into the air path in a direction intersecting a longitudinal direction of the air path;
a heat sink facing the air path; and
a plurality of electronic components attached directly to the heat sink and arranged in the longitudinal direction,wherein the heat sink is spaced apart from the first wall in the direction intersecting the longitudinal direction of the air path.

Abstract
A power supply apparatus includes an air path extending longitudinally, a fan that blows air into the air path in a direction intersecting a longitudinal direction of the air path, and a plurality of electronic components arranged in the longitudinal direction. Each of the electronic components is cooled by air passing through the air path. With this configuration, it is possible to efficiently cool the electronic components without compromising the flexibility of arrangement of the various electronic components. Also, a dust removal operation can be readily performed without the possibility of damaging the fan.

8. A power supply apparatus comprising:
-
an air path; a first wall in which an opening facing the air path is formed; a fan that includes a suction port and a discharge port and that blows air, through the opening, into the air path from the discharge port; a plurality of electronic components that are cooled directly or indirectly by air passing through the air path; and a plurality of walls additional to the first wall, wherein the plurality of walls define a space adjacent to the air path with the first wall intervening between the space and the air path, the plurality of walls include a fan-opposed wall opposed to the suction port via the space, the fan-opposed wall is formed with an intake port portion for guiding air outside the space into the space, and the intake port portion is spaced apart, in an in-plane direction of the fan-opposed wall, from an area of the fan-opposed wall that is in front of the suction port. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A power supply apparatus comprising:
-
a first air path; a first fan that blows air into the first air path; a second air path separated from the first air path; a second fan that blows air into the second air path; a plurality of electronic components that are each cooled by air passing through the first air path or air passing through the second air path; a parting plate interposed between the first air path and the second air path; a first wall in which a first opening facing the first air path is formed; a second wall opposed to the first wall in a first direction that is orthogonal to the longitudinal direction; a third wall in which a second opening facing the second air path is formed; and a fourth wall opposed to the third wall in the first direction; wherein the first air path extends longitudinally, and the second air path extends longitudinally in a longitudinal direction of the first air path, and wherein two ends of both the first air path and the second air path in the longitudinal direction each serve as an exit for air draft, the first fan is located in an intermediate portion of the first air path in the longitudinal direction and blows air into the first air path through the first opening, and the second fan is located in an intermediate portion of the second air path in the longitudinal direction and blows air into the second air path through the second opening. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
