With the rapid development of cloud computing and big data technology, data centers have become important facilities for enterprises and organizations to manage and store information. However, with the continuous expansion of the scale of data centers, problems such as energy consumption and heat dissipation have become increasingly prominent, becoming one of the bottlenecks restricting the development of data centers. This requires the use of an efficient and reliable heat dissipation system to ensure the normal operation of the server. One of the effective cooling methods is liquid cooling technology, and the water pump is its core component. This article will introduce the knowledge of data center server liquid cooling technology and the skills of selecting liquid cooling water pumps.

Data center server liquid cooling solution

When the servers in the data center are running, they consume a lot of electricity and generate a lot of heat. Generally speaking, the temperature in the server room should not be lower than 50°F or higher than 82°F (10°C–27.7°C), while the optimal temperature range is 68° to 71°F (20°C–21.6°C C). To ensure reliable operation and the longest possible service life of the components, the heat generated must be dissipated in good time.

Traditional data center cooling systems usually use air cooling devices or water cooling devices, but these devices are not only expensive, but also consume a lot of energy, are bulky, difficult to install and maintain, and are difficult to adapt to the high requirements of modern data centers for cooling solutions. In addition, traditional cooling systems also face the problem of densely arranged data centers and insufficient space utilization.

Compared with the traditional air cooling method, liquid cooling technology has higher cooling efficiency, can effectively reduce the temperature of the server, and reduce energy consumption and carbon emissions, thereby improving the energy efficiency ratio of the server. In addition, liquid cooling technology can also reduce noise and vibration, improving the reliability and safety of the data center.

Micropumps are used in data center server liquid cooling system

At present, more and more data center servers adopt liquid cooling technology for heat dissipation. In the application of liquid cooling technology, the water pump is a key component.

Usually, the liquid-cooled water pump equipment is installed in the host room of the liquid-cooled system of the data center, and the water is delivered to the cooling equipment in the server rack through the water pipe. In the server rack, the liquid-cooled water pump is usually connected to the radiator to circulate hot water back to the main room of the liquid-cooled system to complete the functions of heat transfer and heat dissipation.

In the server liquid cooling system, the importance of the liquid cooling water pump is self-evident. The heat dissipation effect and stability of the liquid cooling system are directly related to the performance of the water pump. If the performance of the liquid-cooled water pump is not good, it may lead to poor heat dissipation, and even affect the normal operation of the server. At the same time, the stability of the liquid-cooled water pump is also very important. Once the water pump fails, it may have a serious impact on the normal operation of the data center.

Aspects that should be paid attention to when choosing a server liquid cooling water pump

A high-quality liquid-cooled water pump, using advanced brushless DC motor technology and sophisticated fluid mechanics design, can meet the various needs of the data center cooling system, and can be applied to a cooling tower circulation system, heat exchanger circulation system, water tank cooling system and many other aspects.

When choosing a server liquid cooling water pump, it is recommended to focus on the following four aspects:

•Efficiency

The efficiency of the liquid-cooled water pump determines the heat transfer efficiency of the cooling system, which affects the operating efficiency and stability of the server. Therefore, it is necessary to choose a water pump with high efficiency.

• Reliability

The liquid cooling water pump is one of the core components of the liquid cooling system. Once it fails, it may have a serious impact on the normal operation of the data center. Therefore, it is necessary to choose a water pump with high reliability.

• Running sound

The operation of the liquid-cooled water pump will generate noise, which will affect the working environment of the data center and the user experience. Generally, technologies such as low-noise motors and shock-absorbing materials are considered to reduce the noise of the water pump.

• Installation and maintenance

The installation and maintenance of the liquid cooling water pump are very important for the normal operation of the liquid cooling system.

To sum up, when selecting a liquid-cooled water pump, data centers need to comprehensively consider efficiency, reliability, noise, installation, maintenance, etc., and choose a water pump that suits them to ensure the efficient and stable operation of the liquid-cooled system.
