Evaporative phase change cooling server system and control method

Abstract

The invention relates to an evaporative phase change cooling server system and a control method. The system comprises a server cabinet tank, a refrigerant external circulation device and a centralizedmanagement device. The refrigerant nozzle of the server cabinet tank is connected with the refrigerant external circulation device, and is used to spray a liquid refrigerant from the refrigerant nozzle to the key hot spot of the server. After the refrigerant vaporizes and absorbs heat, the gaseous refrigerant is forcedly discharged through a circulation fan in a server cell and liquefied througha cooling coil. The liquid refrigerant is collected through a liquid collecting tank and discharged through a refrigerant external circulation module connected with the liquid collecting tank. The refrigerant external circulation device comprises a refrigerant circulation pump, a refrigerant liquid storage tank and a refrigerant pipe, and is used for completing refrigerant circulation. The centralized management device controls the refrigerant circulation pump and the circulation fan to control the evaporative phase change cooling server. The server cooling system based on the evaporative phase change cooling server has the advantages of low arrangement cost, high compatibility, energy saving and easy maintenance.

Description

technical field [0001] The present disclosure relates to the field of refrigeration, and in particular, to an evaporative phase-change cooling server system and a control method. Background technique [0002] With the rapid development of the new generation of information technology industries such as 5G, Internet of Things, and cloud computing, the demand for data centers is increasing. The power density is also gradually rising, and the power consumption is increasing. At present, the power consumption of China's data centers has increased at a rate of more than 12% for eight consecutive years. It is expected that the total power consumption will reach 296.2 billion kilowatts in 2020. According to the "National Green Data Center Pilot Work Plan", the number of data centers in my country is There are more than 400,000 units, and the annual power consumption exceeds 1.5% of the total electricity consumption of the whole society. Most of the data center PUE is still generally...

Problems solved by technology

However, there are also many problems in the actual operation of this scheme.

[0005] The most typical is that the system uses refrigerant to immerse the server. In a flat server tank, the refrigerant needs to completely fill the entire tank in order to completely submerge the server. In this way, the amount of refrigerant used is too much, and the cost is extremely expensive. During the entire life cycle, The total cost of ownership (TCO) remains high, and there is no commercial value for the application at all

In addition, during operation and maintenance, the system has high requirements on the sealing process, and the refrigerant has a large amount of evaporation and dissipation, which is not suitable for frequent operation, and the operating cost is also very high
