Zusammenfassung:The power supply apparatus has a plurality of power modules, a holder-case housing a parallel arrangement of power modules in a plurality of rows and columns, and a fan. The interior of the holder-case is divided into a plurality of partitions by walls. Wall surfaces follow the contours of power module surfaces to establish cooling ducts of uniform width. The holder-case has flow inlets opened through the first surface plate and exhaust outlets opened through the second surface plate. The power supply apparatus uses the fan to divide and induce air flow through flow inlets into a plurality of partitions, and expels air which has passed through cooling ducts out the exhaust outlets thereby cooling power modules disposed inside the partitions.
