Advanced Single-phase Passive Immersion Cooling Solution with Natural Convection for Outdoor Edge Servers

To meet the increasing demand for AI (artificial intelligence), especially workloads requiring shorter response time like autonomous driving, out-door cloud edge server has drawn more attention and will become widely adopted and deployed in the future. The edge servers deployed in out-door environment need to operate in a wide temperature range ( -40°C to 55 °C) and humidity range (10% to 90%). In order to meet such hash requirements for out-door environment while delivering competitive computing power and density, immersion cooling is one of the efficient solutions. In this topic, a single-phase passive immersion cooling reference solution including system architecture as well as engineering design BKM (Best Known Methods) of both natural convection and force air cooling is presented, which is also purposed to sparkle ecosystem partners of innovation collaboration for more advanced system and thermal solutions for the emerging higher computing demand applications of data center and edge environments.
