Two Examples of CPI Passive Cooling® Cabinet Configurations

September 10, 2015

CPI Passive Cooling® Solutions allow you to manage the flow of air throughout your data center without the need for added cooling system units, in-row air conditioners or liquid cooling solutions. From small applications with heat loads of 2 kW per cabinet, to large data centers with high heat densities up to 32 kW, CPI Passive Cooling Solutions offer smart, proven technology to reduce your data center cooling cost. 

How CPI Passive Cooling Works

  • Controls Airflow – CPI Passive Cooling Solutions control airflow through the cabinet using a specific combination of thermal management accessories. Solutions are available for traditional hot aisle/cold aisle environments and containment.
  • Eliminates Recirculation – CPI Passive Cooling Solutions create a one-way airflow pathway through the cabinet that eliminates the mixing of hot and cold air. The high-density solution, which includes a Vertical Exhaust Duct to isolate hot air from the room, guarantees heat transfer directly from equipment to the cooling unit.
  • Increases Cabinet Density – With a Vertical Exhaust Duct, there is no hot aisle, so cabinet heat loads are not limited by the amount of air that can be delivered through the access floor tiles positioned directly in front of the cabinet.
  • Uses Existing Standard Cooling Equipment – If the cooling capacity of your existing chilled water computer room air conditioners (CRACs) or air handlers (CRAHs) exceeds your heat load, there is no need to add expensive supplemental in-row cooling.
Below are two possible GF-Series GlobalFrame® Gen 2 Cabinet configurations for both low and high heat densities. The F-Series TeraFrame® Gen 3 Cabinet and the N-Series TeraFrame Gen 3 Network Cabinet (for switches) also efficiently manage high density applications.

 

 Example 1: Low Heat Density Application

Combine:

  • GF-Series GlobalFrame Gen 2 with:
    • Perforated Front Door
    • Perforated Rear Door
    • Solid Side Panels
    • Solid Top Panel
     
  • Bottom Panel
  • Air Dam
  • Equipment Rail Grommet Kit
  • Snap-In Filler Panels
  • KoldLok®  Raised Floor Grommet


Example 2: High Heat Density Application

Combine:

GF-Series GlobalFrame Gen 2 with:

  • Perforated Front Door
    • Solid Rear Door
    • Solid Side Panels
    • Solid Top Panel and Vertical Exhaust Duct
    • Bottom Panel
    • Rear Door Sealing Kit 
     
  • Air Dam
  • Equipment Rail Grommet Kit
  • Snap-In Filler Panels
  • KoldLok Raised Floor Grommet
The advantages of this level of air isolation include lower operating costs, an increase of "free cooling" hours, elimination of hot spots, and many more. Take a look at the companies who have benefited from CPI Passive Cooling Solutions.
