Immersion liquid cooling system for green data center

Abstract

The invention provides an immersion liquid cooling system for a green data center. The immersion liquid cooling system comprises external cooling units, chilled water distribution units (CDUs) and liquid cooling cabinet TANK units, wherein each liquid cooling cabinet TANK unit is provided with at least one path of independent external cooling unit and chilled water distribution unit (CDU) for cooling, the external cooling unit is connected with the chilled water distribution unit (CDU) through a pipeline, and the chilled water distribution unit (CDU) is connected with the liquid cooling cabinet TANK unit through a pipeline. According to the invention, cold supply can be guaranteed to the maximum extent; by adopting a constant-temperature and constant-voltage control strategy, the medium temperature is prevented from being too low, electric energy can be saved under low heat load, and the PUE value of a machine room is increased; when the thermal load is low, the flow of the cooling capacity is reduced, so that electric energy is saved; and when the thermal load is small, the rotating speed of P2 is reduced, so that electric energy is saved, and the availability of equipment is improved by switching a main use mode and a filtering mode through V5 and V6.

Description

technical field [0001] The invention relates to the technical field of liquid cooling systems, in particular to a green data center immersion liquid cooling system. Background technique [0002] In recent years, with the rapid development and application of new-generation information and communication technologies such as the Internet, cloud computing, big data, and artificial intelligence, the digital economy, which consists of two aspects of digital industrialization and industrial digitalization, has flourished and its total volume has accounted for More than one-third of my country's GDP also generates massive data that needs to be processed. As the main storage and calculation processing entity of massive data, the scale of the data center is also expanding accordingly, and the resulting energy consumption problem has also received extensive attention. [0003] Traditional data centers usually use air cooling for heat dissipation. Although the application of inter-row a...
