•
•
•
•

Fans are a Problem
Fans Waste Energy
• 15% of total datacenter energy is used to move air
• Additionally fans in the chassis can use up to 20% of IT 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
Structure borne vibration frets electrical contacts
Fans expose electronics to air
• Oxidation/corrosion of electrical contacts
• Exposure to electrostatic discharge events
• Sensitivity to ambient particulate, humidity and temperature conditions

Benefits from Eliminating Fans
Cool High Power Electronics
- Lower operating temperatures result in lower leakage current
- All internal components are kept within normal operating temperature ranges
Save Energy
- For LCS, device power-to-cool can be reduced by up to 98% vs. air-cooled devices
- For LCS, the “true” cooling PUE is ~1.03
- Waste heat easily can be recovered for other uses
Save Space
-
Higher rack density because there is no need for hot aisles or to circulate air in the racks
For LCS, 64 IT devices in a 42U rack or 72 devices in a 48U rack
Increase Reliability
- Sealed fluid circuits prevent failures from corrosion and contamination
- Liquid submersion reduces thermal fatigue of solder joints
Operate Silently - Fan noise is eliminated

Clustered Systems
• Clustered Systems circulates a refrigerant through an external cold plate
mounted on top of each server in the rack.
• Mechanical pressure is used to create contact between the cold plate
and the top of the server.
• Heat is transferred to from the server to the refrigerant by conduction.
• The system requires a refrigerant temperature less than 30oC.

Green Revolution Cooling
• Green Revolution Cooling’s CarnotJetTM system circulates a mineral oil
based dielectric fluid through a tank containing submerged IT devices.
• The system resembles a rack tipped over on its back, with modified
servers inserted vertically into slots in the tank.
• Each 42U tank is filled with roughly 250 gallons of the mineral oil.
• Maintenance access is through the top of the tank

7
Iceotope
• Iceotope mounts off-the-shelf motherboards
inside sealed hot-swappable cartridges that
are flooded with a dielectric fluid, 3M Novec.
• Novec, which remains a liquid, moves heat to
a hot plate mounted on the side of the
cartridge.
• Water circulates in a secondary circuit through
the hot plate, and heat is transferred from
Novec to water in the hot plate by conduction.
• Aster Capital, an investment group backed by
Alstom, Schneider Electric and Solvay,
recently invested $10 million in Iceotope
• Along with the investment Schneider
announced that it intends to commercialize
Iceotope technology

SGI
• SGI uses a two-phase (evaporative) immersion cooled system.
• Electronic components are submerged into a bath of Novec, an expensive
dielectric refrigerant.
• Boiling occurs on the surface of the heat generating devices and vapor passively
rises to the top of the enclosure, where it condenses on water-cooled coils and
falls back into the tank.

LiquidCool Solutions
Patented Directed-Flow Technology
• No fans or other moving parts in the chassis
• Total liquid submersion in a eco-friendly dielectric fluid
• Rack-mounted devices are easy to maintain
• Within a device “cool” liquid is circulated directly to the components with the
highest power density
• The remaining components are cooled by bulk flow as the dielectric fluid is drawn
through the unit to a return manifold
• Electronics are decoupled from the environment
How it Works

10
Heat Dissipation
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 45°C for most applications
© LCS 2014 - Proprietary and Confidential
11
Reliability
LCS technology decouples electronics from the room, eliminating
the root causes of failure:
• Dramatic reduction in thermal fluctuations, which drive solder joint failures
• Much lower operating temperatures for the board and components
(typically 20-30 C cooler device temps than with air)
• No oxidation/corrosion of electrical contacts
• No fretting corrosion of electrical contacts induced by structural vibration
• No moving parts within the device enclosure
(fan failures are one of the highest service triggers for electronics)
• No exposure to electrostatic discharge events
• No sensitivity to ambient particulate, humidity, or temperature conditions
When maintenance is required to upgrade components:
• The swap out procedure takes less than 2 minutes with no measurable loss of fluid
• An IT device can be removed from a rack, drained, opened, serviced, reassembled,
refilled, and reinstalled within a 15 minute turnaround window
