ABSTRACT:
A power supply device includes power semiconductor devices generating Joule's heat by themselves and circuit components generating no considerable heat by themselves but, as a group, generate a slight rise in temperature, which are included in a power supply circuit of the device. A structure is arranged to forcibly cool these semiconductor devices and circuit components by partitioning the interior of a housing of the Dower supply device to form a passage for an air flow, providing the housing with inlet and outlet openings for the air flow and providing the passage with a ventilating fan.
