Description
Technical Field
The invention relates to the technical field of data centers, in particular to a liquid hydrogen energy supply and cooling-based data center.
Background
Data centers are production centers, processing centers and storage centers for information and internet services, and with the rapid development of communication and network technologies, the scale and power density of data centers are increasing. Most of the electronic components of the data center are driven by a low-voltage direct-current power supply to operate. The power consumption cost accounts for more than 20% of all the cost, and is the main cost of the data center. In the traditional data center, nearly 40% of energy is consumed in heat dissipation and refrigeration, and the energy utilization efficiency is very low; therefore, the heat dissipation problem is solved, and a large part of expenses can be saved.
In the past, under a small-scale state of a data center, the operation cost of energy consumption accounts for a small part of the whole operation cost, so most customers can pay more attention to the construction of the data center and ignore the operation cost of the energy consumption, after the climax of the construction of the data center for many years, the scale of the data center is continuously developed, the operation cost is continuously increased, the energy consumption is already the main expenditure in the operation cost, the proportion of the energy consumption cost even reaches 60-70% of the operation and maintenance cost of the data center, and the huge energy consumption cost which cannot be ignored is realized, so that people pay more and more attention to how to reduce the operation cost of the data center by saving the energy consumption.
The continuous development and evolution of modern data centers has led to the continuous increase of energy consumption requirements, which in turn requires better cooling technologies and solutions, mainly wind cooling technology and water cooling technology. Wherein, the air cooling technique includes natural wind refrigeration and single refrigeration through air conditioner or fan, promptly: the temperature difference between the external air temperature and the equipment server is used for cooling the equipment server, but the natural wind refrigeration has the defect of being limited by regions and is not favorable for popularization; the air conditioner or the fan has the defects of high power consumption and high cost.
Compared with the air cooling technology, the water cooling technology has relatively low use cost, and the water cooling technology saves energy by 30 percent compared with the air cooling technology. The water cooling technology mainly adopts a liquid cooling box for loading refrigerating fluid, the server is placed in the liquid cooling box and completely immersed in the refrigerating fluid of the liquid cooling box, during use, the refrigerating fluid in the liquid cooling box can absorb heat generated during the working of the server, and heat exchange is carried out with air through the rethread so as to release the absorbed heat to the air, so that the heat dissipation of the server is realized. However, when the heat absorbed refrigerating fluid exchanges heat with air, if the ambient temperature is high, the absorbed heat is not easily released into the air by the heat absorbed refrigerating fluid, so that the temperature of the refrigerating fluid is rapidly increased and the heat cannot be continuously absorbed, and the server cannot dissipate heat in time and cannot operate safely.
