AI Technical Summary

Technical Problem

Existing liquid cooling units, due to limitations in the capacity and internal layout of the mounting cabinet, can only accommodate one heat exchanger, resulting in low heat exchange capacity and an inability to meet the ever-growing heat exchange demands of data centers.

Method used

Arrange at least two heat exchangers connected in series within a limited space, and change the layout of the expansion tank, makeup water tank and circulating water pump set to arrange them compactly and reasonably in the installation cabinet, increase the number of heat exchangers, use parallel connected water pumps to increase water flow, and optimize the pipeline design through filtration devices and air vents.

Benefits of technology

Higher heat exchange capacity was achieved within a limited installation cabinet space, improving the data center's heat dissipation capacity and enhancing equipment reliability and efficiency.

Abstract

The present disclosure provides a liquid cooling unit, which comprises a mounting cabinet, a heat exchanger group, an expansion tank, a water supplement tank and a circulating water pump group. The heat exchanger group is arranged in the mounting cabinet and comprises at least two heat exchangers connected in series, which are arranged side by side along a first direction. The heat exchanger group is provided with a first liquid inlet end, a first liquid outlet end, a second liquid inlet end and a second liquid outlet end. The first liquid inlet end and the first liquid outlet end are connected to a cold supply device. The second liquid inlet end and the second liquid outlet end are connected to a device to be cooled. The expansion tank, the water supplement tank and the circulating water pump group are arranged in the mounting cabinet and connected between the second liquid inlet end and the second liquid outlet end. In a second direction, the expansion tank and the water supplement tank are located on one side of the heat exchanger group, and the circulating water pump group is located on the other side of the heat exchanger group. The first direction is perpendicular to the second direction. In this way, better heat exchange effect can be achieved in a limited space.
