Abstract
Provided is a power supply unit which is immersed and directly cooled in a coolant filled in a cooling apparatus. The power supply unit includes a unit substrate, and a voltage step-down device mounted on the unit substrate. The unit substrate includes a voltage input terminal for supplying an external power supply voltage, and a voltage output terminal. The voltage output terminal is electrically connected to a voltage input terminal of an electronic device. The power supply unit is mounted on a bottom of a cooling tank of the cooling apparatus so that the electronic device is positioned at an upper part of the power supply unit upon electrical connection between the electronic device and the power supply unit, and cooled by the coolant flowing from the bottom, or flowing from another section of the cooling tank. The unit substrate may be disposed apart from the bottom so as to form a flow channel which allows passage of the coolant between one surface of the unit substrate and the bottom. The voltage step-down device may be configured to include a converter module which steps down the external high voltage DC voltage from 200V to 420V to the DC voltage from 24V to 52V.
