Over the past 10+ years LiquidCool has builtthe most energy efficient, cost effective and

practical approach to data center cooling

Fans are the problem

Fans Waste Energy

• 15% of total datacenter energy is used to move air

• Fans in the chassis can use up to 20% of power at the device level

• Fans are inefficient and generate heat that must be removed

Fans Waste Space

• Racks need room to breathe

• CRAC units require space around the racks

Fans Reduce Reliability

• Fans fail

• Thermal fluctuations drive solder joint failures

• Vibration frets electrical contacts

• Fans expose electronics to air • Oxidation/corrosion of electrical contacts• Sensitivity to ambient particulate, humidity

and temperature conditions

Air is an insulator, not a coolant

» Cooling with Air is Expensive

» Air Cooling Wastes Space

» Air Cooling Limits Power Density

» Air Cooling Reduces Reliability

• Fans Fail

• Air Causes Oxidation and Corrosion

• Air Enables Large Temperature Swings

» Air Cooling Wastes Energy

• Up to 15% of Total Power is used to Move Air• Up to 20% More Power is used by Rack Fans• Fans Generate Heat that must be Dissipated

LiquidCool’s Elegant Solution

Total liquid immersion in a eco-friendly dielectric fluid

• “Cool” liquid is circulated directly to hottest components first. Remaining components are cooled by bulk flow as the dielectric liquid exits the chassis.

• Directed flow is a key differentiator

• No fans or other moving parts in the chassis

• Rack-mounted devices are easy to maintain

• Off-the-Shelf Components

Up to 125°F

Up to 110°F

No Moving Parts – Flow Rate: 0.25 gal / min

No water needed

No water used for cooling when the ambient dry bulb temperature is less than 110oF

LCS Cooling System Elements

• Pump supplies “cool” dielectric liquid to multiple IT racks

• If there is no energy recycling option, “hot” fluid is circulated to an evaporative fluid cooler

• Incoming “cool” fluid can be as warm as 110oF for most applications, which completely eliminates the need to use water almost anywhere in the world

What LCS Does Not Need

• Mechanical Refrigeration

• Cooling Towers

• Air Handlers

• Humidity Control

• Blade and Rack Fans

• Mixing Dampers

• High Ceilings

• Hot Aisles

• Noise

• Water

• Very much space

Case Study: Facebook (Altoona, IA Data Center)

Facebook Data Center after LCS

LCS saves Facebook (MILLIONS)

» LCS eliminates the need for a 3 story building

» LCS uses a fraction of the floor space

» LCS eliminates 1.4 million cubic feet of air per minute

» LCS eliminates DX units for dehumidification when indoor RH exceeds 85%

» LCS eliminates evaporative cooling when outdoor temperature is over 85°F

» LCS saves not only upfront capex but also the energy to run the facility

LCS eliminates all of that!

3rd Party Validation

Lawrence Berkeley National Laboratory

• Lawrence Berkeley National Laboratory assessed LiquidCool technology for the US Navy’s Transformative Reductions in Operational Energy Consumption (TROPEC) program for continuous operation of servers and communication/network equipment in tropical environments with no mechanical cooling.

• The Coefficient of Performance for the LCS system was 49.9 at full load compared to 1.6 for current practice, 30 times better.

National Renewable Energy Laboratory• Preliminary data from the testing program, currently underway, suggest that more than 85% of

the electric energy used by LCS servers can be recycled to create hot water for building heat.

• The test program will conclude in November at which time the LCS rack and servers will be moved to NREL’s high performance computing center.

Intel Corporation• Confirmed that the LCS dielectric fluid does not have a deleterious effect on Intel processors,

and all processor cores and memory operated well within the normal operating range even at coolant temperatures of 122°F

• As a result of this study and other investigations it undertook, Intel committed to extend normal warranty terms to processors immersed in the dielectric fluid LCS employs.

Competition

Three Liquid Cooling Technologies:1. Cold Plates – Requires Fans

– Shifts heat from processors but does not save much energy– Mechanical cooling needed above 85oF– Maximum rack density is 30-kilowatts

2. In-Row Cooling – Requires Fans– Makes the room smaller – Mechanical cooling above 80oF– Maximum rack density is 35-kilowatts

3. Total Immersion in a Dielectric Fluid – No Fans; > 75kW rack densityGreen Revolution CoolingIceotope
