We are pleased to share that our recent article titled “Effective energy use and passive cooling in data centers using heat pipes and PCM-integrated TEG systems” has been published in the Journal of Energy Storage.
Led by Dr. Murat Emre Demir, the study introduces a novel passive cooling system that combines thermoelectric generators (TEGs), phase change materials (PCMs), and heat pipes to improve energy use in data centers. Applied to a 25 kW server rack, the conceptual system generates 125 W of power, delivers 67.8 °C hot water, and achieves 80% energy and 33% exergy efficiency with minimal reliance on active cooling systems such as CRAC units. The study also introduces a new performance metric—the Exergy Reuse Factor (ExRF)—to evaluate the quality of recovered heat.
