September 2006 - CPI Passive Cooling™ Solutions, Achieving Innovative Thermal Management

CPI Passive Cooling SolutionsWESTLAKE VILLAGE, Calif., September 2006—Chatsworth Products, Inc. (CPI), a leading manufacturer of systems designed to organize, store and secure IT infrastructure equipment offers new CPI Passive Cooling™ Solutions to solve thermal management challenges.

Passive cooling is an innovative technique that allows you to control the flow of air through cabinet spaces. CPI Passive Cooling™ Solutions provide 2-20+ kW of cooling without the use of uncertain supplemental liquid or active cooling systems. This safe solution allows customers to reclaim control over airflow so that cool air can be directed where it is needed, eliminating bypass and re-circulation of hot exhaust air and the formation of hot spots.

CPI Passive Cooling Solutions provide flexibility, scalability, Tier IV capabilities and the ability to minimize total cost of ownership. These solutions allow uncomplicated moves, adds and changes while also permitting customers to configure a solution designed to meet their specific needs. Adaptable for increasing density requirements, CPI Passive Cooling Solutions accomplish high heat density cooling while achieving advanced thermal control with zero points of failure. In addition, CPI Passive Cooling Solutions maximize CRAC effectiveness, decrease ongoing maintenance costs and reduce the risks and costs associated with supplemental liquid or active cooling systems.

To maximize effective cooling capacity, it is important to manage airflow through, over and around equipment cabinets. CPI Passive Cooling Solutions, available with the TeraFrame™ Cabinet System help achieve the ultimate thermal management solution by reclaiming airflow control and improving cooling effectiveness in the data center with low, medium or high heat density CPI Passive Cooling Solutions.

CPI's low heat density solution achieves 2-4 kW of cooling by eliminating hot air recycling through the cabinet. Begin by blocking airflow through open rack spaces with CPI's Snap-In Filler Panels, diminishing hot air re-circulation to the font of the cabinet. Close off space where air can go around the sides, top and bottom of equipment mounting spaces with the Air Dam Kit. Effectively this will create a front-to-rear barrier to airflow and will lower the temperature of air entering the top half of the cabinet because hot air is not re-circulated through the cabinet. Air still re-circulates over the cabinet, but now travels in a one-way direction through equipment.

Increasing the amount of cold air entering the cabinet will help to attain 4-7 kW of cooling, therefore providing a medium heat density solution. To increase the amount of cold air available to each cabinet, seal cable holes with the KoldLok® Raised Floor Grommet and block airflow through open rack spaces with Snap-In Filler Panels. Use CPI's patent pending Internal Air Duct instead of the Air Dam Kit to deliver additional cold air to the top half of the cabinet. This cold air will lower the temperature of air directed to the upper portion of the cabinet, thereby reducing the negative effects of hot air traveling over the cabinet into the cold aisle.

Overcome a high heat density solution by isolating hot air from the room to accomplish 7-20+ kW of cooling. Use CPI's patent pending Vertical Exhaust Duct System (includes; Vertical Exhaust Duct, Server Top Panel, Airflow Director and Rear Door Sealing Kit) with the Air Dam Kit, KoldLok Raised Floor Grommet and Snap-In Filler Panels to create a ducted exhaust cabinet. Hot air will be isolated from the room and returned to the primary cooling system through the drop ceiling plenum or ducted return positioned high above the cabinet. Because hot air is isolated in the duct, you can place vented access floor tiles in the hot aisle to deliver additional cold air to equipment. The resulting lower room temperature eliminates the need for supplemental liquid or active cooling systems.

Use CPI's Product Configurator at to customize your TeraFrame Cabinet System with CPI Passive Cooling Solutions and achieve the ultimate data center thermal solution. Once you have configured your solution receive a BOM, rendered drawings and a selection of global distributors.
