Liquid Thermal Management

 

 

The RFM-304883-LC is the perfect infrastructure solution for retrofitting into existing Data Centers or new builds. Created in response to escalating processor speeds and high thermal density created by clustered blade computing, The RFM-304883-LC helps maximize space utilization while minimizing operating costs in high density applications.

The RFM-304883-LC uses a closed-loop, liquid cooling, system to route cool air from the base of the enclosure through a built-in plenum duct, delivering an exhaust free, measured stream of cooling air to all servers mounted inside the enclosure. Sealed from external temperatures and cooled by an integrated thermal-management system, the RFM-304883-LC becomes a Virtual Data Center in a Cabinet.

Factory equipped with strategic security features, such as an automatic door-opening system and variable-speed fans for optimum system performance and economy, the RFM-304883-LC can also be equipped with a range of optional security accessories.

RFM-304883-LC with Standard Cooling solutions



The RFM-304883-LC is a Rack Mount Unit, 19” EIA enclosure system, with an integral Closed Loop Cooling System that relies on a supply of low pressure Chilled Water channeled through a high efficiency Heat Exchanger mounted in the base of the enclosure to absorb heat energy generated by Servers and other related rack mounted equipment.

The 3 system Fans, utilized for removal of warmed air from the servers, are variable speed and are operated by independent temperature controls allowing for greater economy of operation when the RFM-304883-LC is not operating under a full load. To facilitate up-time operation, a fan can be replaced while the system is running.

Front and Rear doors are equipped with Thermostatically Controlled Automatic Release Systems designed to open in the event of a cabinet reaching a user preset temperature condition.

Why use water rather than air to remove heat from ‘high density’ thermal loads?
• Physics: Water is 3650 times more efficient at heat removal than air
• Availability: chiller plants supplying water to CRAH’s is the norm in 80% ~ 90% of existing sites
• Real Estate: (5 x) RFM-304883-LC cabinets, operating at nominal 20kW per rack, can replace (10 x) medium density racks at 10kW or (20 x) low density racks at 5kW

When is it time to seriously consider RFM-304883-LC closed loop water cooling solution?
• The practical limitation per enclosure, in terms of energy load, is between 5kW and 14kW. At values in excess of this level, overall efficiency of displacement of Data processing equipment to allow for additional HVAC systems and support gear, goes into decline

Specifications:
• Total Rack Height: 45U
• Usable Height: 37U

Cooling Components:
• 3 EC Backed Curved Impellers (Fans)
• Operating point: 0% at 20deg. C., 100% at 40deg. C
• 230VAC (200-270VAC) Nominal voltage, 2.9A current draw
• Individual fan thermal speed control
• The RFM-304883-LC is typically set to a temperature
above the dew point so the risk of condensation is eliminated
