What is liquid cooling server rack?

liquid cooling server rack is a server system that uses liquid cooling technology to reduce server temperature. Traditional servers usually use air cooling to dissipate heat, while liquid-cooled servers use liquid media to directly contact the heat dissipation components to effectively absorb and remove the heat generated.

The working principle of liquid cooling server rack is to introduce cooling liquid (usually water or a dedicated liquid cooling medium) into the server system, flow along the surface of the heat dissipation component, and absorb the generated heat. The heat is then transferred to the coolant through the heat exchanger to external heat dissipation equipment (such as a cooling tower or cooling plate), so that it can dissipate heat and cool it down before being recycled again, keeping the server running more stable and reducing noise compared to air-cooled servers. , the noise of the liquid cooling server rack will be reduced a lot, creating a quiet and low-carbon data center.

Reasons for using liquid cooling server rack

The emergence of liquid cooling server rack has greatly reduced energy consumption and noise. Due to the continuous growth of server computing power, the heat dissipation density per unit area is getting higher and higher. The air-cooling heat dissipation solution has reached the upper limit. The cold plate liquid cooling solution using air-liquid mixed heat dissipation is adopted. Or a fully liquid-cooled immersion liquid cooling solution, which can not only effectively solve the heat dissipation problem but also reduce server energy consumption.

Compared with traditional air-cooling technology, liquid cooling has the advantages of reducing energy consumption, maintaining stable system performance, and supporting higher-power processors. It uses liquid instead of air to take away the heat generated by heating devices such as CPU and memory. In terms of efficiency, liquid cooling is at least 15% to 20% higher than air cooling. It has become a key force to further reduce PUE and has developed rapidly in recent years.

Advantages of liquid cooling server rack

1. Large heat capacity and high heat dissipation efficiency

Liquid cooling technology reduces data center temperatures by using liquid as a heat transfer medium. This relies on the liquid in direct contact with the heat source to dissipate heat. Liquid cooling removes most of the heat through the circulating medium, thereby reducing the air requirements of individual servers and the overall need for air circulation in the server room, significantly reducing local hot spots caused by backflow in the server room.

In addition, the heat transfer effect of liquid is much better than that of air, and it can absorb a large amount of heat while maintaining a stable temperature, thereby greatly improving the heat dissipation efficiency.

2. Reduce energy consumption and expenses

Data centers consume large amounts of electricity in their operations, which is associated with expensive electricity bills. With the move to liquid cooling solutions, fans and air conditioners that continuously consume power can be replaced in whole or in part, significantly reducing power consumption and costs.

3. Improve energy efficiency, protect the environment and reduce noise

Liquid cooling systems can reduce the overall energy consumption and energy efficiency of a data center to a significant degree. In addition, because the pumps and other instruments of a liquid cooling system are quieter than fans, liquid cooling systems are much less noisy than air cooling systems, thus creating a “quiet data center.”

Summarize

Our cold plate liquid-cooled servers have the advantages of low energy consumption, high heat dissipation, low noise, and low TCO. They are large servers deployed in cabinets and are equipped with liquid leakage detection functions.

With the demand for large amounts of data and large computing power, the problem of carbon emissions caused by high energy consumption in data centers has made “green data centers” receive widespread attention in recent years. Our company has created a new cold-plate liquid-cooled server. After intensive testing, it meets user needs. It not only solves the problem of high noise, but also solves the problem of low heat dissipation efficiency. If you have any needs or questions, please feel free to inquire!
