Abstract: A rack-based information handling system (IHS) includes a rack having a modular structure that supports insertion of different numbers and sizes of information technology (IT) gear to create one or more IT nodes. A fan bay module is attached to the rack and supports insertion of multiple different fan configurations in more than one fan receptacle. At least one fan is inserted within corresponding at least one fan receptacle of the fan bay module to conform to at least a first fan configuration. A block controller is configurable to control each of the different fan configurations and which, in response to detecting the first fan configuration of the at least one fan inserted within the fan bay module, activates a corresponding first control algorithm that enables the detected first fan configuration to be utilized to provide rack-level cooling for one or more of the IT nodes inserted within the rack.

Abstract: An information handling system includes: an immersion server drawer (ISD) having: an impervious enclosure which holds a volume of dielectric cooling liquid within/at the enclosure bottom. The ISD is configured with dimensions that enable insertion of liquid-cooled servers within the enclosure bottom. A plurality of liquid-cooled servers can be placed in a side-by-side configuration along one dimension of the ISD, with one or more heat dissipating components of the servers being placed below a surface layer of the cooling liquid. Submerged components of the immersion server are liquid-cooled, while the other heat generating components above the liquid surface are air cooled by rising vapor generated by boiling and vaporization of the cooling liquid. The ISD is placed in an ISD cabinet, which is configured with an upper condenser that allows for multi-phase cooling of the electronic devices placed within the immersion server drawer. The ISD cabinet can be rack-mountable.

Abstract: A method that controls pressure within an immersion cooling tank having condensation fluid flowing through a condenser, includes: a controller receiving a signal that indicates a current level of vapor pressure within the tank; determining from the signal when the current level of vapor pressure exceeds or is below a first preset threshold pressure level; and in response to the current level of vapor pressure exceeding or being below the first preset threshold pressure level, signaling a flow control mechanism that modulates a flow rate of the condensation fluid through the condenser to increase or decrease the rate of flow from a current rate of flow. The controller receives the signal by a pressure sensor within the immersion cooling tank detecting the current vapor pressure, generating the signal and forwarding the signal to the controller. The pressure sensor can be a differential pressure transducer that measures a differential pressure internal to and outside of the immersion tank.

Abstract: A system for cooling hard disk drives (HDDs) includes: an enclosure having a lower volume within which a cooling liquid is heated to a boiling point temperature to cause some of the cooling liquid to evaporate into a plume of rising vapor; a HDD cooling area with at least one HDD placed in the direct path of the rising vapor, which cools the at least one HDD during functional operation of the at least one HDD; and a heat source that dissipates heat into the lower volume of the enclosure, sufficient to heat the cooling liquid to the boiling point temperature. The system can also include a condenser located above both the HDD cooling area. A substantial portion of the rising vapor that passes through the HDD cooling area and cools the at least one HDD is condensed back into liquid phase on contact with the condenser.

Abstract: A stand-alone immersion tank datacenter (SITDC) includes: a multi-phase heat transfer immersion cooling tank having external walls surrounding a tank volume within which a dielectric liquid is maintained and heated to a boiling point temperature; a plurality of servers having one or more processing and memory components submerged within the dielectric liquid for cooling of the one or more components via heat dissipation from the one or more components into the dielectric liquid when the one or more components are connected to an electric power supply; and a condenser located vertically above the plurality of servers and in a direct path of rising dielectric vapor created when the dielectric liquid absorbs sufficient heat from the one or more components to reach a boiling point temperature of the liquid. The condenser can be a passive heat exchanger, created by providing a heat conductive material as a top lid of the tank.

Abstract: An immersion server includes: a first surface that is exposed when the server is submerged within a cooling liquid; and at least one vapor bubble deflector physically abutting the first surface and extending away from the first surface at an angle. The deflector divides the first surface into an upper segment and a lower segment when the server is upright. When the server is submerged, the cooling liquid surrounding the lower segment absorbs sufficient heat to evaporate and generate vapor bubbles rising to the liquid surface. The vapor bubble deflector deflects the rising vapor bubbles away from the surface of the upper segment. This enables superior liquid contact with heat dissipating components at the upper segment and better cooling of those components. The deflector can be a device-level deflector separating two or more components or a component-level deflector separating a lower segment from an upper segment of a single component.

Abstract: An immersion cooling tank includes: a tank comprised of a base wall, and perimeter walls, and having a lower tank volume in which a liquid can be maintained and heated to a boiling point to generate a rising plume of vapor; a rack structure within the tank volume that supports insertion of multiple, heat dissipating electronic devices in a side-by-side vertical configuration; and a condenser configured as a plurality of individually rotatable condenser sub-units, with each condenser sub-unit located above a vertical space that extends vertically from the lower tank volume and within which an electronic device can be inserted. Each individual condenser sub-unit can be opened independent of the other sub-units and each other condenser sub-unit can remain in a closed position while a first condenser sub-unit is opened to allow access to a first vertical space and any existing electrical device contained therein below the first condenser sub-unit.

Abstract: A system for heat exchange includes a first condenser that places a first working fluid vapor in proximity to a second working fluid liquid. The two working fluids have respective saturation temperatures that enable the second working fluid to absorb sufficient amounts of heat from the first working fluid vapor to vaporize, while the first working fluid vapor condenses back into a liquid. The second working fluid vapor exits the first condenser via a first conduit and enters a first heat exchanger which places the second working fluid vapor in proximity to a third working fluid. The relative saturation temperatures of the second and third working fluids enables the transfer of sufficient amounts of heat from the second working fluid vapor to cause the second working fluid vapor to condense back into liquid while at least a portion of the third working fluid liquid vaporizes into third working fluid vapor.

Abstract: A fluid level control system includes: a first immersion cooling tank having a first volume of immersion cooling liquid and an inlet/outlet pipe extending from a base wall of the tank by which immersion cooling liquid can flow into and out of the first immersion cooling tank; at least one second volume of cooling liquid held within a liquid containing unit having a corresponding inlet/outlet pipe; and a pipe distribution system that physically connects the second volume of immersion cooling liquid to the first volume of immersion cooling liquid via respective inlet/outlet pipes and which enables fluid equilibrium to be maintained between the first volume of liquid and the second volume of liquid via gravitational equilibrium and/or passive level control such that a first volume level of the first volume of immersion cooling liquid remains substantially equal to a second volume level of the second volume of immersion cooling liquid.
