摘要： A space-saving, high-density modular data pod system and an energy-efficient cooling system are disclosed. The modular data pod system includes a central free-cooling system and a plurality of modular data pods, each of which includes a heat exchange assembly coupled to the central free-cooling system, and a distributed mechanical cooling system coupled to the heat exchange assembly. The modular data pods include a data enclosure having at least five walls arranged in the shape of a polygon, a plurality of computer racks arranged in a circular or U-shaped pattern, and a cover to create hot and cold aisles, and an air circulator configured to continuously circulate air between the hot and cold aisles. Each modular data pod also includes an auxiliary enclosure containing a common fluid and electrical circuit section that is configured to connect to adjacent common fluid and electrical circuit sections to form a common fluid and electrical circuit that connects to the central free-cooling system. The auxiliary enclosure contains at least a portion of the distributed mechanical cooling system, which is configured to trim the cooling performed by the central free-cooling system.

摘要： A cooling system includes a heat exchanger having one or more rows of multiple flat tubes, louvered fins disposed between pairs of flat tubes, and special header tube connections to form a counter flow heat exchanger. Heat exchangers having multiple rows may be placed near or close to the server racks and may be in fluid communication with an outdoor heat exchanger having one or more rows. A single-phase fluid is pumped through a fluid circuit or loop, which includes the heat exchangers at the server racks and the outdoor heat exchanger. The single-phase fluid circuit including the heat exchangers at the IT racks may alternatively be in thermal communication with a water circuit that includes an outdoor fluid cooler. The flat tubes can be formed tubes with one or more channels, or extruded tubes with multiple channels. The heat exchangers include header tubes/connections, which facilitate easy fabrication and connection between rows and inlet/outlet, and lower the pressure drop.

摘要： The cooling systems of the present disclosure include a first refrigerant circuit in thermal communication with a heat load and in fluid communication with a main condenser, a free cooling circuit in fluid communication with the main condenser and a free-cooled water source, a chilled water circuit in fluid communication with the main condenser and an evaporator, and a second refrigerant circuit in fluid communication with the evaporator and a secondary condenser. The free cooling circuit is in thermal communication with the first refrigerant circuit via the main condenser, the chilled water circuit is in thermal communication with the first refrigerant circuit via the main condenser, and the second refrigeration circuit is in thermal communication with the chilled water circuit and the free cooling circuit. The second refrigeration circuit cools a fluid flowing in the chilled water circuit. Methods of operating a cooling system are also disclosed.

摘要： An air flow distribution system for cooling server racks includes at least one server rack partially defining a hot aisle and a cold aisle, a first air foil disposed above the server rack, and a second air foil disposed above the first air foil. The first air foil and the second air foil are configured to receive air from the hot aisle, and to form turbulent wake patterns in the cold aisle partially defined by the server rack. The air flow distribution system may include a convex ceiling member above the second air foil. A corresponding method includes causing air to be directed between a first air foil disposed above a server rack and a second air foil disposed above the first air foil to form turbulent wake patterns in the cold aisle. An electrical enclosure assembly includes a receptacle and a cover member configured as an air foil.

摘要： Electrical systems for providing uninterruptible power to a critical load. One electrical system includes a ring bus, multiple power blocks including one or more generators electrically coupled to the ring bus, and uninterruptible power supplies (UPSs) electrically coupled to the ring bus. In some aspects, the electrical system includes a UPS switchgear electrically coupled between the ring bus and the UPSs. In other aspects, the UPSs are electrically coupled together in parallel. Another electrical system includes a utility switchgear, UPS blocks electrically coupled together in parallel and electrically coupled to the utility switchgear via transformers, low voltage (LV) power blocks electrically coupled to the UPS blocks, and medium voltage (MV) switchgear electrically coupled to the UPS blocks via transformers. Each of the LV power blocks include one or more generators.

摘要： Systems and methods for supplying power (both active and reactive) at a medium voltage from a DCSTATCOM to an IT load without using a transformer are disclosed. The DCSTATCOM includes an energy storage device, a two-stage DC-DC converter, and a multi-level inverter, each of which are electrically coupled to a common negative bus. The DC-DC converter may include two stages in a bidirectional configuration. One stage of the DC-DC converter uses a flying capacitor topology. The voltages across the capacitors of the flying capacitor topology are balanced and switching losses are minimized by fixed duty cycle operation. The DC-DC converter generates a high DC voltage from a low or high voltage energy storage device such as batteries and/or ultra-capacitors. The multi-level, neutral point, diode-clamped inverter converts the high DC voltage into a medium AC voltage using a space vector pulse width modulation (SVPWM) technique.

摘要： A power supply system includes an energy storage device electrically connected to a power grid, a power distribution assembly electrically connected to a load, and a power generation device electrically connected to the power distribution assembly. The energy storage device and the power grid are configured to supply electric power having a first voltage range to the power distribution assembly, which in turn, is configured to supply electric power having a second voltage range less than the first voltage range to the load. The energy storage device and the power generation device each are configured to at least temporarily supply a flow of electric power to the power distribution assembly when electric power from the power grid is interrupted such that a substantially uninterrupted flow of electric power is supplied to the load.
