Immersion Cooling – Past and PresentMore Efficient Than Air, Water or Oil PAST - Has been around since the era of the Cray-2 supercomputer, PAST - Has been considered too advanced and costly for non-military applications until recently. PRESENT - At this day and age, this assumption is simply not true any longer and we cannot afford to

ignore this elegant solution to the high density cooling challenge. PRESENT - Traditional cooling systems that use air, water or oil are complex and costly. Open bath immersion cooling offers:

― A simpler, true alternative solution, saving large amounts of energy, greenhouse emissions and space.

― resolves a number of today’s engineering bottlenecks, allows manufacturers to build better hardware without heat transfer constraints, while also being much cheaper and less complex to build.

It's an open and future proof platform and it will play an important role in solving the energy crises we see in datacenters today.



Immersion Cooling In a two-phase (evaporative) immersion cooled system,

electronic components are submerged into a bath of dielectric heat transfer liquids, which are much better heat conductors than air, water or oil. With their low boiling points (ie. 49°C vs. 100°C in

water), they boil on the surface of the heat generating devices and rising vapor passively takes care of heat transfer. No fans or pumps are required for this process. No need for conventional cooling hardware with better

cooling efficiency. Compared to traditional air or water cooling, this passive

process results in the use of much less energy.



2-Phase Liquid Immersion CoolingOperating Principle

Servers are placed side-by-side in a lidded bath of dielectric fluid.

Devices cause fluid to boil. Rising vapor condenses on a condenser cooled

by facility water. Servers plug into an immersed backplane. Power and IO enter/exit through a conduit that terminates below the liquid level. Servers can be hot-swapped and leave the bath dry. The bath is “semi-open” as it is at atmospheric pressure. Bath breathes through a trap (not shown).

Immersion CoolingHigher Density Without the restrictions and overhead of traditional cooling

methods offers a much higher density, improved performance and the possibility for applications that would otherwise be impractical.

With a smaller package, lower power consumption and much less supporting infrastructure (ie. no chillers or air conditions), the choice of facilities becomes much less restrictive.

Eliminates the Heat Transfer Overhead for Product Designers

Our passive immersion cooled systems free the designer from all the overhead of a heat transfer system.

For developers, time to market can be greatly improved, Engineers focus on building the application instead of finding

ways to get the heat out.

Future-Proof (future hardware works without any changes) In an immersion cooled system, new hardware does not require any

resources for the heat transfer process. In other words, your immersion cooling enclosure will work with all your future hardware too. Out with the old, in with the new.

Non-proprietary - Universal Design Immersion cooling systems don't lock customers in to one

technology. What goes in enclosures and what connects to them is completely up to the end-user.

This holds true for server level hardware (inside the tank) and for facility level infrastructure.



Immersion CoolingImproved Performance and Reliability Hardware benefits from lower junction temperatures

and improved performance, no temperature swings or hot spots, and generally runs more reliable.

No unnecessary parts to build or service since the cooling system is passive and not attached to the hardware

Extremely Clean2-phase immersion cooling system has positive side effects on both, the device and facility level: Massive air flow, dust and noise are eliminated from the

facility. Having no fans, bulky heatsinks or air channels on the

hardware level results in a very clean and elegant design.

Board removal (swap) will come out dry, due to low temperature evaporation.

Zero Ozone Depletion Potential & Inherent Fire Protection

3M™ Novec™ Engineered Fluids have an excellent environmental, health and safety profile.

Novec fluid does not deplete ozone (zero ozone depletion potential) and has a very low global warming potential.

It is non-toxic and non-flammable. Because of its low global warming potential, Novec is used in

gas fire extinguishing systems by companies such as IBM in data centers worldwide.

technology. What goes in enclosures and what connects to them is completely up to the end-user.

This holds true for server level hardware (inside the tank) and for facility level infrastructure.



Immersion CoolingAdvantages of Immersion Cooling: Higher efficiency and energy savings (>90% electricity savings) Reduced capital and operational expenses Improved performance Higher density Improved hardware reliability Faster time to market Fits any form, size or shape of electronics components and boards Non-flammable, inherent fire protection Works in confined spaces and extreme environments (hot & humid etc). Reduced environmental impact



Power used for cooling <1% of IT power *

Immersion-2Real cost of ownership data are being generated during the building and start-up of Immersion-2. Built by Allied Control for a client in hot humid Hong Kong, the 500kW system started up with a PUE<1.01.

Conceptual Drawing of Immersion-2

Traditional Air Cooled DC• 4 kW/rack • 35 racks = 140 kW• 1 SQM per kW

Immersion-2•24 kW/rack

Immersion-2•75 kW/rack

When compared with a conventional air cooled data center, the space saving achievable with the Immersion-2 racks is dramatic, particularly if the racks are populated at their 75kW capability. Potential savings in real estate costs and annual

electricity expenditure for 10MW facility in Singapore
