Graphene enhanced immersion cooling for data centers

Important results from the project

Yes. The primary goal established at the beginning of the project was to validate the application of GT-TIM graphene pad in the domain of immersion cooling. The work carried out within the projects have demonstrated that the liquid environment didn’t degrade the GT-TIM pad, and that its thermal performance remained comparable to that in the air-cooled conditions. The findings also suggested that GT-TIM contribute to an improved performance compared to the thermal paste and indium foil.

Expected long term effects

These results have contributed to broaden the horizon of application of Smart High Tech’s GT-TIM products. These products were developed intended for air-cooling usage, but the results have demonstrated that GT-TIM can be adapted for immersion cooling environments, which can lead to their usages in data center, high-performance computing and advanced power electronics. The compatibility of GT-TIM in immersion cooling may influence the material selection of thermal management product market.

Approach and implementation

This project was carried out according to a strict timeline with monthly meetings to monitor the process and align with goals. Chalmers and SHT collaborated closely, through frequent in-person interaction. Communication between partners was facilitated by teams and email. SHT coordinated the whole project, while SHT and Chalmers were responsible for product development and characterization respectively, RISE was responsible for performance validation in the immersion cooling environments.
