Power supply apparatus including fan for air cooling

摘要

A power supply apparatus includes an air path (109) extending longitudinally, a fan (108) that blows air into the air path (109) in a direction intersecting a longitudinal direction of the air path (109), and a plurality of electronic components (103) arranged in the longitudinal direction. Each of the electronic components (103) is cooled by air passing through the air path (109). With this configuration, it is possible to efficiently cool the electronic components (103) without compromising the flexibility of arrangement of the various electronic components (103). Also, a dust removal operation can be readily performed without the possibility of damaging the fan (108).
