In a controller for a fluid conditioning unit, a fluid conditioning system including a plurality of fluid conditioning units, and a method of conditioning a fluid, each fluid conditioning unit includes a unit controller configured to operate the fluid conditioning unit. One unit controller of the plurality of the unit controllers may function as a master control module and provide at least one operational set point to each of the unit controllers. The controller may include instructions stored therein that cause the controller (i) to operate as a unit controller controlling the fluid conditioning unit and (ii) to operate as a master controller. The method may include selecting a new unit controller to function as the master control module from the unit controllers of the plurality of fluid conditioning units when the previous unit controller operating as a master control module for the fluid conditioning system goes offline.

Systems and methods for cooling a datacenter are disclosed. In at least one embodiment, a chemical property monitoring subsystem (CPMS) is associated with one or more flow controllers to determine a change in chemistry associated with a primary coolant or a secondary coolant, so that one or more flow controllers can cause a change in coolant state of a secondary coolant or a primary coolant based in part on a change in their chemistry.

An environmental control system is provided. The environmental control system can include a cooling device and a heating device. The cooling device can lower the temperature of fluid contained within a cold reservoir and the heating device can raise the temperature of fluid contained within a hot reservoir.

Embodiments of the invention provide a system and method for housing electrical components of a high-density liquid cooling unit to liquid cool electrical components. The system includes a first electrical cabinet housing at least one electrical switch and a controller. The first electrical cabinet is swingable outward to open, and the first electrical cabinet opens while the high density liquid cooling system continues to operate to liquid cool electrical components. The system includes a second electrical cabinet housing a first motor drive and a second motor drive. The second electrical cabinet is accessible when the first electrical cabinet swings outward. One of the first motor drive and the second motor drive are replaceable while the high density liquid cooling unit continues to operate.

Embodiments are disclosed of a cooling device. The cooling device includes a housing enclosing an internal volume, the housing having at least a heat transfer contact surface adapted to be thermally coupled to a heat-generating electronic component. A partition is positioned in the internal volume; the partition divides the internal volume into a liquid compartment and a vapor compartment, and the partition has a gap therein to allow fluid movement between the liquid compartment and the vapor compartment. A liquid inlet is fluidly coupled to the liquid compartment; a liquid outlet is fluidly coupled to the vapor compartment; and a vapor outlet is fluidly coupled to with the vapor compartment. Embodiments of cooling systems including design and operation using the cooling device are also disclosed.

Embodiment of the present invention generally relate to the field of thermal capacity management within data centers, and more specifically, to methods and systems which provide feedback based on thermal information associated with parts of a data center. In an embodiment, the present invention is a method comprising the steps of using temperature measurements and power meter readings to provide real-time capacity usage information in a given data center and to use that information to perform moves/adds/changes with a particular level of confidence.

A data center and an expansion method are provided to avoid a phenomenon of dense cables during data center expansion. In the data center, a first power device is connected to a computing device by using a bus, and a plug-in node and an idle electrical connection end are pre-disposed on the bus. In this way, when expansion is required, a second power device for expansion is directly added to the idle electrical connection end, and the bus is disconnected by using the plug-in node. In this way, the first power device and the second power device for expansion respectively supply power to the computing device by using two parts of the disconnected bus. According to this mode, no additional cable is required during the data center expansion, but an existing cable is directly disconnected to support power supply of a power device for expansion.

This disclosure describes systems for arranging racks within a data center for a smaller and/or more flexible footprint, more efficient and/or resilient cooling, and/or easier installation. In some examples, this disclosure describes a data center rack system that includes an aisle and a plurality of rack stations adjacent to the aisle. The aisle includes an aisle guidance track defining an aisle axis. Each rack station of the plurality of rack stations includes a station guidance track defining a station axis. The station guidance track is configured to receive a rack from the aisle guidance track and position the rack in the respective rack station at a rack angle formed between the aisle axis and the station axis that is less than 90 degrees.

Systems and methods to provide a prefabricated module design for heterogeneous data centers are described. An apparatus to provide cooling for an electronic rack of a data center comprises a plurality of lines. A main chassis is coupled to the plurality of lines. The main chassis is configured to be integrated on the electronic rack. An extension chassis is coupled to the main chassis. The extension chassis is configured to move relative to the main chassis. A plurality of connection ports are coupled to the extension chassis to provide connections between the electronic rack and one or more external sources. The plurality of connection ports are configured to move relative to the plurality of lines that are at fixed locations on the electronic rack.

In one example, a shell includes walls that collectively define an interior space of the shell, the interior space sized and configured to receive heat generating equipment. An internal heat exchanger disposed within the interior space is arranged for thermal communication with heat generating equipment when heat generating equipment is located in the interior space. Additionally, an external heat exchanger is located outside of the shell and arranged for fluid communication with the internal heat exchanger. Finally, a prime mover is provided that is in fluid communication with the internal heat exchanger and the external heat exchanger, and the prime mover is operable to circulate a flow of coolant through the internal heat exchanger and the external heat exchanger.
