Online pluggable cabinet-level spraying liquid cooling system and control method

Abstract

The invention discloses an online pluggable cabinet-level spraying liquid cooling system and a control method. The system comprises a server cabinet body, a refrigerant external circulation device anda centralized management device. The server cabinet body is divided into a plurality of cabinet liquid cooling units, and refrigeration of a server is completed by making contact with key heating points through a refrigerant. The refrigerant external circulation device is used for intensively storing a liquid refrigerant into a refrigerant liquid storage tank, pressure of a refrigerant pipe is adjusted through a refrigerant circulating pump and a low-temperature refrigerant is conveyed into the server cabinet body to finish refrigerant circulation. The centralized management device is used for receiving a server working state parameter acquired by an acquisition device, calculating refrigeration requirements of the key heating points of each server through a preset algorithm, and controlling the refrigerant circulating pump and a circulating fan so as to control the system. The liquid cooling system has advantages of high adaptability and low arrangement cost.

Description

technical field [0001] The present disclosure relates to the field of refrigeration, in particular, to an online plug-in cabinet-level spray liquid cooling system and a control method. Background technique [0002] With the rapid development of new-generation information technology industries such as 5G, the Internet of Things, and cloud computing, the amount of data has surged. According to IDC statistics, the global data stock reached 16ZB in 2016, and it is expected to grow to more than 40ZB by 2020, or as high as 160ZB by 2025. The surge in data volume has led to the accelerated development of the global cloud computing industry, and the data center IDC, as the underlying IT infrastructure, directly benefits. [0003] At present, the power consumption of China's data centers has grown at a rate of more than 12% for eight consecutive years. It is estimated that the total power consumption will reach 296.2 billion kilowatts in 2020. According to the "National Green Data Ce...

Problems solved by technology

However, in the actual operation of these liquid solutions, there are many problems

[0007] The most typical is that the above-mentioned cold plate liquid cooling system or other server-level liquid cooling systems not only require in-depth customization of the server (modification of the server, installation of a precision backplane, and expensive self-sealing quick connectors), but also require the server manufacturer to completely Changing the form of existing products, producing new server products to match the existing refrigeration system, the applicability is poor, and the liquid cooling system has many movable joints (at least 2 for each server), the risk of online plugging and unplugging is high, and there are serious problems. leakage risk

[0008] There is also an immersion liquid cooling system, which requires the refrigerant to completely immerse the server. The amount of refrigerant used is too much, and the initial investment cost CAPEX is extremely high. During operation and maintenance, a large amount of refrigerant evaporates and dissipates, and the operating cost OPEX is also very high. If Frequent online plugging and unplugging operations will further increase the OPEX of the operating cost. The total cost of ownership (TCO) of this type of liquid cooling system is extremely high and has no application value

[0009] How to solve the problem of server adaptability, risk-free and low-cost online plug-in problem, and high cost of total cost of ownership (TCO) involved in the current liquid cooling system has become a problem to be solved
