Mineral Oil-Based Direct Liquid Cooling System

SESSION: Emerging Technologies Exhibits

EVENT TYPE: Emerging Technologies

EVENT TAG(S): SoC for HPC

SESSION CHAIR(S): Simon McIntosh-Smith, Sadaf R. Alam

ROOM:14

ABSTRACT:

Direct liquid cooling is one of the promising cooling solutions for data center servers. It reduces operating expenses and energy consumption. Moreover, it minimizes floor spaces for servers. Metal plates are attached to server components and the coolant, typically water, flows through the plates. The goal of this project is to develop a new direct liquid cooling solution that uses electrically non-conductive mineral oil instead of water. To overcome the low thermal conductivity of mineral oil, we designed special cooling plates for CPUs and GPUs that maximizes the liquid-contacting area and circulation systems that maximize the flow rate. As a result, our system keeps the temperature of CPUs and GPUs below 70ºC at full load. This is the first mineral-oil-based direct liquid cooling solution that is safe, cheap, high density, and easy to maintain. ManyCoreSoft Co., Ltd. has released the MCS-4240 cluster system that uses our liquid cooling solution.
