Louvered rack

A method for cooling at least one electronic component housed in a rack, said method comprising:

• receiving a sensed temperature of the at least one electronic component;
• determining whether the sensed temperature is within a predetermined range;
• determining whether the sensed temperature is above a predetermined maximum set point temperature;
• manipulating a movable louver to increase delivery of a cooling fluid to the at least one electronic component in response to the sensed temperature being above the predetermined maximum set point temperature;
• and
• manipulating a movable louver to decrease delivery of a cooling fluid to the at least one electronic component in response to the sensed temperature being below the predetermined maximum set point temperature.

A system for cooling one or more electronic components in a rack, said system comprising:

• means for sensing the temperature of the one or more electronic components;
• means for determining whether the sensed temperature is within a predetermined range;
• and
• means for manipulating the airflow through the rack in response to the sensed temperature of the one or more electronic components being outside of the predetermined range to thereby vary the flow of cooling fluid delivery to the one or more electronic components.

A data center comprising:

• a plurality of racks, each of said plurality of racks, having one or more movable louvers positioned on at least one of an inlet and an outlet of each of the plurality of racks;
• a cooling system operable to supply said plurality of racks with cooling fluid to thereby cool electronic components located within the plurality of racks;
• and
• a plurality of louver controllers configured to operate the one or more movable louvers to vary the supply of cooling fluid into the plurality of racks, said louver controllers being configured to operate the movable louvers to reduce re-circulation of the cooling fluid with air heated in the plurality of racks.

A data center comprising:

• a rack having one or more movable louvers positioned on at least one of an inlet and an outlet of the rack;
• a cooling system operable to supply said rack with cooling fluid to thereby cool electronic components located within the rack, wherein said cooling system comprises a vent having a vent controller configured to determine airflow through said vent, said cooling system further comprising a pressure sensor configured to measure the pressure within a plenum positioned to supply cooling fluid to said vent;
• and
• a louver controller configured to operate the one at more movable louvers to vary the supply of cooling fluid from the plenum into the rack.

A method of reducing re-circulation of air in a data center having at least one rack and at least one vent for supplying cooling fluid to the at least one rack, said at least one rack having one or more movable louvers, said method comprising:

• determining the mass flow rate of airflow through the at least one rack;
• determining the muss flow rate of airflow through the at least one vent;
• computing the mass flow rate of airflow through the at least one rack and the at least one vent;
• and
• manipulating the one or more movable louvers in response to the comparison of the mass flow rates through the at least one rack and the at least one vent to reduce re-circulation of air in the data center.
