With the booming digital economy, the pace of new construction and expansion of data center is gradually accelerating, traditional air-cooling technology has been difficult to meet the requirements of data center for low energy consumption. Liquid-cooling technology not only can meet the needs of data center with high density and low energy consumption, but also can greatly improve the stability, efficiency and service life of servers. Furthermore, it can increase the density of single cabinet by more than 10 times compared to air-cooling, and save more than 70% energy, which is well recognized in the data center industry.

As a leading data center service provider in the industry, Kehua has been actively promoting the development of data center liquid-cooling technology industry, increasing R&D investment and continuous innovation, solving the problems of high energy consumption and low efficiency of traditional cooling methods, and meet the demand for liquid cooling deployment in various data center scenarios.

l Urgent needs: high performance and low energy consumption

The Tan Kan Kee Innovation Laboratory, which lies in Xiamen University, one of China’s most prestigious university, plays a significant role in gathering innovative resource and contributing to the innovative strategy in the field of energy materials.

With the high growth in demand for scientific computing in the fields of energy, materials, and semiconductors, the lab is in urgent need of building a high-performance, low-energy data center. 

After preliminary analysis, the floating point arithmetic power of the Supercomputing Center needs to reach at least 1150 trillion times/second to meet future R&D and application requirements. This means that the arithmetic power is increased and the heat dissipation capability must also meet higher requirements.

To face up with the challenge, Kehua provides WiseMDC Series Intelligent Liquid-cooling Data Center Solution for the Tan Kan Kee Innovation Laboratory, injecting new vigor into it.

l Intelligent application: cold-plate liquid cooling technology brings new vigor

To meet the demand of high computing power, the solution breaks through the use of cold-plate liquid cooling technology, air-liquid synergistic cooling to meet the demand of high-density heat dissipation. The single cabinet power density can be up to 50kW, and the PUE can be less than 1.2.

The power components of the cooling system are all controlled by frequency conversion, which can achieve maximum energy-saving operation according to the load and outdoor environment.

The solution adopts the design concept of dual redundancy at product level + device level, and adopts Kehua 400kW liquid-cooled CDU. Dual CDU and dual pumps monitor multi-dimensional parameters such as temperature, pressure to achieve precise control and healthy management, ensuring high safety and reliability of system operation.

In order to reduce the reliance on manual operation and maintenance in the Smart Computing Center, in this solution, the whole chain of liquid cooling system can be dynamically adjusted to achieve precise control on demand. At the same time, the system can be remotely and centrally monitored, with real-time dynamic monitoring display and fault warning.

l Future expectation: Preparing for expansion to help industrialization development

At present, the Jiageng Lab has been put into use, and the performance of the system in terms of computational density and o&m has far exceeded the project's expectations. In this program, the Smart Computing Center is highly extensible, leaving operational space for future expansion.

This solution is an important exploration and practice of Kehua in the liquid-cooling data center. In the future, Kehua will make continuous innovation and breakthroughs in the field of liquid-cooling technology, create more efficient and energy-saving liquid-cooling products, accelerate the data center into a new era of liquid-cooling, and explore a green and low-carbon data center innovation development path.
