Title:
ELECTRONIC DEVICE FOR LIQUID IMMERSION COOLING, POWER SUPPLY UNIT, AND COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/087903
Kind Code:
A1
Abstract:
Provided are an electronic device and a power supply unit that are immersed in a coolant inside a cooling device and directly cooled. The electronic device includes: a carrier substrate comprising a voltage input terminal that supplies DC voltage for the electronic device; a plurality of module connectors arranged on one surface of the carrier substrate; a plurality of module substrates; a plurality of supporting plates that hold both ends of the plurality of module substrates; and a supporting member that supports the carrier substrate. The voltage input terminal is electrically connected to a voltage output terminal in the power supply unit. Each of the plurality of module substrates has a module connector plug electrically coupled to each of the plurality of module connectors. The supporting member supports the carrier substrate so as to be positioned in an upper section of the power supply unit arranged in the bottom section of a cooling tank provided in the cooling device, when the electronic device is electrically connected to the power supply unit. The power supply unit has: a unit substrate; a voltage step-down device mounted on the unit substrate; and a stage having the unit substrate fixed thereto.
