Modular data centers have gained popularity in recent years due to their ability to be rapidly deployed to remote areas and provide a supplement to traditional brick-and-mortar data centers. However, cooling remains a significant challenge in these compact spaces. To address this issue, the U.S. Department of Energy’s ARPA-E launched the COOLERCHIPS program in May, funding projects aimed at developing highly efficient and reliable cooling technologies for data centers. One such project is the HoMEDUCS project, which focuses on extracting and dissipating heat from computer chips into the ambient air.
The Significance of Cooling in Modular Data Centers
Cooling is of paramount importance in modular data centers due to their tight spaces and the intense heat generated by the high-performance computer chips they house. Liquid-based immersion cooling or evaporative cooling techniques are commonly employed to ensure efficient heat dissipation and prevent overheating.
The COOLERCHIPS Program
In line with the growing demand for efficient cooling technologies in data centers, the COOLERCHIPS program aims to fund projects like HoMEDUCS that can significantly reduce energy consumption and improve the overall reliability of cooling systems.
The HoMEDUCS Project
The HoMEDUCS project focuses on the direct liquid cooling technique to extract and dissipate heat from computer chips. By utilizing a unique cold plate design and innovative heat exchangers, HoMEDUCS reduces energy requirements and eliminates the need for compressors or chillers.
Driving Heat Away from the Chip
HoMEDUCS harnesses the temperature difference between the computer chip and the ambient air to efficiently drive heat away from the chip. This approach maximizes the cooling potential while minimizing energy consumption.
Incorporating Radiative Cooling Panels
To further enhance cooling efficiency, the HoMEDUCS project incorporates radiative cooling panels on the roof of the module. These panels facilitate cooling of the liquid below ambient temperatures without the need for electricity, adding an additional layer of energy savings.
Projected Energy Consumption and Water Requirements
The cooling design of HoMEDUCS is projected to use less than 5% of a data center’s total power consumption. This significant reduction in energy consumption not only results in cost savings but also decreases the strain on energy grids. Additionally, HoMEDUCS’s cooling system does not require water, eliminating the potential environmental impact associated with traditional cooling methods.
Broader Applications and Goals
While the primary focus of the COOLERCHIPS program is data center cooling, its broader goal is to develop technologies that can be applied to other electronic systems as well. For example, the efficient cooling techniques developed through this program can also be used in power conversion systems for solar and wind turbines, further reducing energy consumption and enhancing overall system performance.
Impact on Modular Data Centers
Modular data centers stand to benefit greatly from the technologies developed through the COOLERCHIPS program. Their ability to quickly adapt and utilize efficient cooling systems will enable them to operate more efficiently and meet the growing demands of data storage and processing.
The HoMEDUCS project, funded by the ARPA-E COOLERCHIPS program, is at the forefront of developing highly efficient cooling technologies for modular data centers. By utilizing direct liquid cooling, unique cold plate designs, innovative heat exchangers, and incorporating radiative cooling panels, HoMEDUCS aims to significantly reduce energy consumption and eliminate the need for water. The technologies developed through the COOLERCHIPS program will not only benefit modular data centers but also have broader applications in other electronic systems, contributing to a more sustainable and energy-conscious future.
