Liquid-cooled power supply cabinet and data center cooling system using the same

Abstract

A liquid-cooled power supply cabinet includes a shelf, at least one liquid-cooled power supply chassis, a coolant heat exchange unit, and a coolant distribution pipe. The liquid-cooled power supply chassis is arranged on the shelf, which includes a coolant input / output unit for transmitting a first coolant to absorb a heat energy. The coolant heat exchange unit is fluidly connected to the liquid-cooled power supply chassis, so that the first coolant flows through the coolant heat exchange unit via the coolant input / output unit and returns to the liquid-cooled power supply chassis. The coolant distribution pipe is fluidly connected to the coolant heat exchange unit, and is used to transmit a second coolant, so that the second coolant flows into the coolant heat exchange unit, and the second coolant and the first coolant perform heat exchange in the coolant heat exchange unit. The first and second coolants are different media.
