The invention combines systems and methods for heat containment and cold air isolation for managing airflow and temperature in data centers. The data center contains at least two rows of cabinets containing heat-generating equipment and arranged to form a cold aisle and a hot aisle. The data center system includes panels or doors at both ends of the cold aisle and an optional cover over the cold aisle to inhibit cooled air supplied by an air conditioning system from exiting the cold aisle and inhibit air warmed by the heat-generating components from entering the cold aisle. A chimney coupled to the top, rear, or top and rear of the cabinets is configured to exhaust the warmed air into a region above the rows of cabinets. The chimneys may be ducted to a plenum or suspended ceiling or to the intake of the air conditioning system. Baffles and/or fans may be included in the chimneys, ducts, and/or plenums to control the air pressure. The invention may also include one or more data center air conditioning units, and each air conditioning unit may be configured to service one or more rows of cabinets. Alternatively, or in addition, cool air may be supplied by the building's air conditioning system.

1. A system for use in a data center having a source of cool air, the system comprising: a first set of cabinets, each cabinet of the first set of cabinets comprising a generally rectangular vertical front face, two generally rectangular vertical side faces coupled to the front face, a generally rectangular top face coupled to the side faces and to the front face, a generally rectangular back face coupled to the side faces, and an interior that is adapted to house one or more heat-generating components, each of the cabinets adapted to intake the cool air, wherein the first set of cabinets are arranged in a first row and a second row horizontally displaced from each other such that the front faces of the cabinets in the first row are facing the front faces of the cabinets in the second row to define a cold aisle between the front faces;a first baffle proximate the front face of a first cabinet in the first row and the front face of a first cabinet in the second row, the first baffle being configured to inhibit horizontal airflow into and out of the cold aisle;a second baffle proximate the front face of a last cabinet in the first row and the front face of a last cabinet in the second row, the second baffle being configured to inhibit horizontal airflow into and out of the cold aisle;at least one chimney in communication with at least one cabinet of the first set of cabinets in the first row, the at least one chimney configured to conduct air warmed by the heat-generating components to a location above the cabinets;at least one chimney in communication with at least one cabinet of the first set of cabinets in the second row, the at least one chimney configured to conduct air warmed by the heat-generating components to a location above the cabinets;wherein the at least one chimney in communication with at least one cabinet of the first set of cabinets in the first row is carried by the top and back faces of the at least one cabinet of the first set of cabinets in the first row; andwherein the at least one chimney in communication with at least one cabinet of the first set of cabinets in the second row is carried by the top and back faces of the at least one cabinet of the first set of cabinets in the second row;a first duct in communication with the at least one chimney of the first set of cabinets in the first row, the first duct configured to conduct air warmed by the heat-generating components from the location above the cabinets to an air conditioning unit;the air conditioning unit being configured to supply the cool air to the data center;a second set of cabinets, each cabinet of the second set of cabinets comprising a generally rectangular vertical front face, two generally rectangular vertical side faces coupled to the front face, a generally rectangular top face coupled to the side faces and to the front face, a generally rectangular back face coupled to the side faces, and an interior that is adapted to house one or more heat-generating components, each cabinet of the second set of cabinets adapted to intake the cool air, the second set of cabinets are arranged in a third row horizontally displaced from the first row formed by the first set of cabinets such that the back faces of the cabinets in the third row are facing the back faces of the cabinets in the first row to define a first hot aisle between the back faces;a third set of cabinets, each cabinet of the third set of cabinets comprising a generally rectangular vertical front face, two generally rectangular vertical side faces coupled to the front face, a generally rectangular top face coupled to the side faces and to the front face, a generally rectangular back face coupled to the side faces, and an interior that is adapted to house one or more heat-generating components, each cabinet of the third set of cabinets adapted to intake the cool air, the third set of cabinets are arranged in a fourth row horizontally displaced from the second row formed by the first set of cabinets such that the back faces of the cabinets in the fourth row are facing the back faces of the cabinets in the second row to define a second hot aisle between the back faces;at least one chimney in communication with at least one cabinet of the second set of cabinets in the third row, for conducting air warmed by the heat-generating components to a location above the cabinets; andat least one chimney in communication with at least one cabinet of the third set of cabinets in the fourth row, for conducting air warmed by the heat-generating components to a location above the cabinets. 2. The system of claim 1, where the chimney defines an air passageway that is in fluid communication with the interior of the cabinet, the air passageway comprising an inlet for taking in air leaving the cabinet and an outlet for conducting the air out of the air passageway to the location above the cabinets. 3. The system of claim 1, where the top face of each cabinet defines a first opening leading to the rack interior, the first opening located at the back of the top face, proximate the back face; where the back face of each cabinet defines a second opening leading to the cabinet interior, the second opening located at the top of the back face, proximate the top face; andwhere the chimney defines an air passageway that encompasses and is in fluid communication with the first and second openings, the air passageway comprising an inlet for taking in air leaving the cabinet, and an outlet for conducting the air out of the air passageway to the location above the cabinets. 4. The system of claim 1, where the chimney includes a fan. 5. The system of claim 1, where the chimney is in communication with the top face of the cabinet. 6. The system of claim 1, where the cool air is delivered to the cold aisle through a plurality of perforations in a floor of the data center. 7. The system of claim 1, where the cool air is delivered to the data center through the bottoms of the cabinets. 8. The system of claim 1, where the cool air is delivered directly into the cold aisle through one or more ducts. 9. The system of claim 1, further comprising at least one duct in communication with the chimney, is configured to conduct air warmed by the heat-generating components to a suspended ceiling. 10. The system of claim 9, where the duct comprises a fan or baffle. 11. The system of claim 9, where the duct comprises a fan or baffle. 12. The system of claim 1, further comprising at least one duct in communication with the chimney, is configured to conduct air warmed by the heat-generating components directly to an intake of at least one of the air conditioning units. 13. The system of claim 1, where at least one of the first baffle or the second baffle comprises a door. 14. The system of claim 1, where at least one of the baffles comprises a window. 15.
