Description

Technical Field

[0001] The present invention relates to the technical field of data centers, and in particular to a liquid cooling system for a data center. Background Art

[0002] Traditional data center computer rooms generally use room-level air conditioning and under-floor air supply cooling. This method has low construction cost and high computer room utilization rate, and can be used to solve the heating of 3-5kW single cabinets. However, with the large-scale application of rack-mounted and blade servers in computer rooms, the number of devices in a single cabinet, power density, and heat density have increased significantly. Traditional computer room-level air conditioning can no longer solve the heat dissipation problem of IT equipment, and row-level air conditioning and backboard air conditioning have emerged. This new type of air conditioning terminal is closer to the heat source, which can solve the problems of local hot spots and high heat density. Through close-range cold transmission, it reduces the power consumption of the fan and achieves energy saving. Whether it is room-level air conditioning, row-level air conditioning, or backboard air conditioning, it first cools the air and then cools it down by heat exchange between the cold air and the server's CPU. Due to the low heat exchange efficiency and heat flux density of air, air-cooled servers have problems such as high cooling energy consumption, high noise, and low equipment density. In order to solve the heat dissipation problem of ultra-high power density IT equipment, data centers have begun to adopt liquid cooling technology, using working fluid as the medium for intermediate heat transmission to transfer heat from the heat zone to a distant place for cooling. The cooling efficiency of liquid cooling technology is significantly higher than that of air cooling, which can effectively solve the heat dissipation problem of high-density servers, reduce the energy consumption of the cooling system and reduce noise.

[0003] However, the existing data center liquid cooling system can generally only use cooling liquid as a cooling method. In most parts of my country, the winter is cold, and liquid cooling is not as good as directly using air cooling sources for cooling. If the cold sources in the environment can be fully utilized, it will further reduce the cooling energy consumption of the data center.

[0004] Therefore, there is an urgent need for a data center liquid cooling system that can solve the above problems. Summary of the invention
