Immersion-indirect contact combined liquid cooling system for data center

Abstract

The invention provides an immersion-indirect contact combined liquid cooling system for a data center. According to the invention, an immersed liquid cooling technology and a contact liquid cooling technology are combined, and the problems that the loss of a pump is large, the greenization degree of a data center is reduced and the like in traditional single-phase direct immersed liquid cooling are solved. The liquid cooling system of the invention comprises a liquid cooling cabinet, a cooling capacity distribution unit, a water chilling unit, heat removal equipment, a liquid storage tank, a refrigerant pump and the like. The liquid cooling cabinet comprises a liquid cooling box body, a server and layer-mounted cold plates, wherein a single-phase refrigerant is contained in the box body, the server is immersed in the single-phase refrigerant, and the layer-mounted cold plates are fixed in the box body in a non-uniform mode from bottom to top. According to the invention, the pump can beprevented from driving a high-viscosity single-phase refrigerant and the single-phase refrigerant can be prevented from circularly flowing outside the box body, the system can complete replace a compressor to operate throughout the year, the refrigeration of the data center by utilizing a natural cold source is truly realized, the PUE value of the data center is improved, and the cooling effect of the data center is ensured while energy is saved.

Description

technical field [0001] The invention relates to the technical field of data center cooling devices, in particular to a data center liquid cooling system combining immersion and indirect contact. Background technique [0002] The data center is a large power consumer. The electronic information equipment and refrigeration units that operate continuously throughout the year consume a lot of power. Effective heat dissipation methods for the data center to reduce the power consumption of the refrigeration unit are conducive to the energy saving of the entire data center. The arrival of the 5G era will further increase the power consumption and heat dissipation of the data center, bringing new challenges to the existing heat dissipation technology of the data center. [0003] Immersion liquid cooling is a new heat dissipation technology that has attracted the attention of the industry in recent years. Immersion liquid cooling has clear advantages. First, in the immersion liquid...
