Description
Technical Field
The utility model belongs to the technical field of liquid cooling energy conservation, and particularly relates to a movable cold source for an immersed liquid cooling data center.
Background
In order to cope with the urgent needs of high-performance AI data centers, such as high density, high energy consumption, low PUE, low WUE, and low CUE, and the needs of high-performance computing and the increase of density, the data centers need a great deal of energy consumption to cope with the power needs of IT equipment, power supply and refrigeration equipment, so as to solve the heat dissipation problem of the server. Traditional forced air cooling heat dissipation has been difficult to succeed, utilizes insulating coolant liquid to with the advantage of immersion liquid cooling and waste heat utilization, promotes the power center to adopt the immersion liquid cooling scheme, and future powerful times, immersion liquid cooling data center will become market mainstream.
At present, a chilled water air conditioning system (central air conditioner) is mainly selected for a medium-sized and large-sized data center, and a cold accumulation energy storage technology is generally selected as a cold source backup for realizing continuous cold supply. A direct expansion air conditioning system (split air conditioner) is mainly selected as the miniature data center, and a single-phase immersed data center adopting insulating cooling liquid is free to refrigerate by adopting a natural cold source, so that no continuous cooling technology and no continuous cooling product are guaranteed at present.
An emergency refrigerating system of a large-scale data center is a refrigerating system for controlling the temperature of the data center in an emergency situation. When the main air conditioning system is stopped temporarily due to faults, the emergency refrigerating system can immediately relay refrigerating work, so that the emergency refrigerating system is also known as the 'insurance' of the data center. For a data center with high power and high heat flux, the emergency refrigerating system can be further improved in running reliability. In addition, the AI calculation data center has high power density, the value of a single server is high, and once redundant auxiliary machine components are damaged, an online maintenance function is required to reduce the influence on the whole system so as not to influence the normal operation of the service.
Generally, emergency refrigeration systems can be divided into two main types, namely, a double-cold-source air-conditioning system and a cold-storage refrigeration system according to different cold sources. Accordingly, there is a need in the art to develop a compound refrigeration system.
