Intel and Submer’s robust technological collaboration aimed at establishing a formidable foundation for single-phase immersion technology has achieved a groundbreaking advancement in the form of the Forced Convection Heat Sink (FCHS) package. Set to revolutionize datacenter cooling, the FCHS reduces the quantity and cost of components required for comprehensive heat capture and the dissipation of chips with Thermal Design Power (TDP) exceeding 1000W.
“Many have challenged the technological runway of single-phase immersion cooling. The Forced Convection Heat Sink is the undeniable proof that immersion is here to compete head-on with other liquid cooling technologies, including Direct Liquid Cooled water-based cold plates.”Daniel Pope, Co-Founder and CEO of Submer
Enabling the Cooling of CPUs for Generations to Come
Marking the first milestone in the journey towards the 1kW+ chip, Submer and Intel’s immersion cooling 800W+ Xeon processor with Forced Convection Heat Sink (FCHS™) technology delivers an array of key highlights for the datacenter industry.
The FCHS package combines the efficiency of forced convection with passive cooling, enabling the cooling of high TDP CPUs and GPUs in single-phase immersion systems. Its fail-proof design also enables natural convection in the event of propeller failure.
The FCHS is not only highly efficient but also cost-effective. Its components are cheap to manufacture and even present the possibility of being 3D printed.
Designed for easy retrofitting into any existing server and immersion tank setups, the FCHS empowers datacenters to swiftly handle high-density compute workloads.
Competitive Thermal Performance
The FCHS delivers thermal resistances that rival those of Direct Liquid Cooling (DLC), making it a formidable competitor in the liquid cooling landscape. If desired, the package returns thermal management to the server by enabling BIOS PWM control.
This technological breakthrough paves the way for even higher TDPs and future collaborations, solidifying single-phase immersion as a leading cooling solution.
“An immersion heat sink utilizing forced convection is a key innovation in taking single-phase immersion cooling beyond the current barriers allowing single-phase immersion not only to be a solution of today but also a solution of the future!”Mohan J Kumar, Intel Fellow
The FCHS is undoubtedly a momentous event in the world of cooling, providing a simple, cost-effective solution for cooling chips up to the 1000W range in single-phase immersion systems. The FCHS package will be officially debuted on the 17th-19th of October 2023 at the OCP Global Summit with live demonstrations showing results in real-time. All the details of this technology can be found in Intel and Submer’s case study.
Founded in 2015, Submer provides best-in-class technology, enabling datacenters around the world to leverage the power of immersion cooling for HPC, hyperscale, datacenters, Edge, AI, DL, and blockchain applications. Submer is headquartered in Barcelona, Spain, and operates a Gigafactory in Houston, Texas. For more information, visit submer.com.
