Description

Technical Field

[0002] As the scale of data centers continues to expand and computing loads continue to increase, energy consumption and heat dissipation issues in data centers have become particularly prominent. In order to meet these challenges, liquid-cooled CDU has gradually become a hot technology in the data center industry. Liquid-cooled CDU equipment, with its high efficiency, energy saving and stability, provides an ideal heat dissipation solution for data centers.

[0003] CDU (Cooling Distribution Unit) is a thermal management device based on liquid cooling technology. Its core task is to transfer the heat generated by the data center to the cooling medium, and then dissipate the heat from the cooling medium through the cooling system. The liquid-cooled CDU equipment transports the cooling medium to the equipment that needs to be cooled through a series of pipes and pumps. When the cooling medium flows through these equipment, it will come into direct contact with the heat source, absorb and take away the generated heat. The warm cooling medium is then transported to the heat exchanger for heat dissipation, and then returned to the cooling medium supply system through the pipe, forming a cyclic heat dissipation process.
