Title: ELECTRONIC DEVICE FOR LIQUID IMMERSION COOLING, POWER SUPPLY UNIT, AND COOLING SYSTEM
Abstract:
Provided is an electronic device that is 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; and a supporting member that supports the carrier substrate. The voltage input terminal is electrically connected to a voltage output terminal in a power supply unit. 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 supporting member can include a backboard or a frame structure that have the carrier substrate fixed to one surface thereof. The backboard or frame structure can be slidably supported by a plurality of support columns vertically erected and fixed inside the cooling tank. The backboard or frame structure can include a support pin or guide pin inserted, from above, into a bracket fixed inside the cooling tank.
