Abstract

Described herein is an integrated data center that provides for efficient cooling, as well as efficient wire routing.

Claims

1. A facility with an internal area and an external area in an external environment for maintaining electronic equipment disposed in a plurality of cabinets, the cabinets formed in cabinet clusters in the internal area at a cool temperature, the facility comprising:

a building that includes an exterior load wall separating the internal area and the external area;

a plurality of exterior wall openings in the exterior load wall;

a floor within the internal area of the building on which the plurality of cabinet clusters are disposed;

a plurality of cabinets forming a first row of cabinets and a second row of cabinets forming a cabinet cluster for holding the electronic equipment therein, the plurality of cabinets positioned with a back of the first row of cabinets facing a back of a second row of cabinets so that the electronic equipment disposed within the plurality of cabinets receive cool air from a cold aisle at a cabinet front side and emit heated air from a back side of each row of cabinets toward a hot air aisle located between the first row and the second row;

a plurality of support brackets associated with a cabinet cluster, disposed along the first row and the second row, the support brackets extending upward from the floor and above the cabinets to support wiring and conduits;

a thermal shield supported by at least some of the plurality of support brackets, the thermal shield located above the cabinet clusters to form a contiguous wall around the hot air aisle to form a hot air containment chamber that is above the hot air aisle to contain heated air and cause substantially all the heated air within the hot air aisle to rise up from the hot air aisle to the hot air containment chamber;

a warm air escape gap within the building disposed above the hot air containment chamber, the warm air escape gap providing a passage for the heated air to the plurality of exterior wall openings in the exterior load wall;

a plurality of air conditioning units disposed external to the building such that the air conditioning units are configured to receive heated air from the warm air escape gap through the exterior wall openings and emit cooled air; and

cool air ducts coupled to the air conditioning units to receive the cooled air, the cool air ducts located within the building and extending from the air conditioning units to the cold aisles, the cool air ducts being disposed below warm air escape gap.

2. The facility according to claim 1 further including:

a plurality of backup electric generators operable upon a gas fuel and which provide a gaseous exhaust, the backup electric generators providing backup electricity in case of a power-down condition to power the electrical equipment; and

a spring-loaded mechanical closing lever associated with each of the plurality of air conditioning units, the spring-loaded mechanical closing lever causing automatic closure of the outside air damper upon a disruption in electrical power.

3. The facility according to claim 1 wherein there are a plurality of cabinet clusters arranged in an array, so that the cold aisle provides cool air to a plurality of cabinet clusters.

4. The facility according to claim 1 wherein the wiring provides redundant power to each of a plurality of power units associated with each cabinet cluster.

5. The facility according to claim 1 further including a plurality of distribution power units that supply power to the cabinets via power distribution wiring such that all of the power distribution wiring is located above the plurality of cabinets.

6. The facility according to claim 1 wherein the plurality of support brackets each include:

a plurality of tiered ladder rack supports having ladder racks thereover to establish a plurality of different tiers in the cold aisle along the thermal shield, such that each of the different tiers is adapted to hold the electronic equipment power wires and conduits and the communication wiring, and

a plurality of conduit holders disposed above the plurality of tiered ladder rack supports, each of the conduit holders in each of the plurality of support brackets aligned with corresponding ones of conduit holders in the other plurality of support brackets.

7. The facility according to claim 1 further including physical fencing and a lockable door around a periphery of the cabinet cluster.

8. The facility according to claim 1 wherein the plurality of air conditioning units further receive outside air.

9. A facility with an internal area and an external area for maintaining electronic equipment disposed in a plurality of cabinets, the cabinets formed in cabinet clusters in the internal area, the facility comprising:

a building that includes an exterior load wall separating the internal area and the external area;

a plurality of exterior wall openings in the exterior load wall;

a floor within the internal area of the building on which the plurality of cabinet clusters are disposed;

a plurality of cabinets forming a first row of cabinets and a second row of cabinets forming a cabinet cluster for holding the electronic equipment therein, the plurality of cabinets positioned with a back of the first row of cabinets facing a back of a second row of cabinets so that the electronic equipment disposed within the plurality of cabinets receive cool air from a cold aisle at a cabinet front side and emit heated air from a back side of each row of cabinets toward a hot air aisle located between the first row and the second row;

a plurality of support brackets associated with a cabinet cluster, disposed along the first row and the second row, the support brackets extending upward from the floor and above the cabinets;

a thermal shield supported by at least some of the plurality of support brackets, the thermal shield located above the cabinet clusters to form a contiguous wall above the hot air aisle to form a hot air containment chamber located above the hot air aisle to contain heated air and cause substantially all the heated air within the hot air aisle to rise up from the hot air aisle to the hot air containment chamber;

a warm air escape gap within the building disposed above the hot air containment chamber, the warm air escape gap providing a passage, for the heated air, to the plurality of exterior wall openings in the exterior load wall;

air conditioning units disposed external to the building such that the air conditioning units are configured to receive heated air through the exterior wall openings, from the warm air escape gap, and emit cooled air; and

cool air ducts, coupled to the air conditioning units, to receive the cooled air, the cool air ducts extending from the air conditioning units to the cold aisles and located below the warm air escape gap.
