[0002] This is a PCT application of U.S. Patent Application No. 17 / 238,384 filed on April 23, 2021. The disclosure of this application is incorporated herein by reference in its entirety for all purposes. Technical Field

[0003] At least one embodiment is directed to cooling systems, including systems and methods for operating such cooling systems. In at least one embodiment, such a cooling system may be utilized in a data center containing one or more racks or computing servers. Background Art

[0004] Data center cooling systems use fans to circulate air through server components. Some supercomputers or other high-capacity computers may use water or other cooling systems instead of air cooling systems to draw heat from server components or racks in the data center to areas outside the data center. The cooling system may include chillers within the data center area (which may include areas outside the data center itself). In addition, the area outside the data center may include a cooling tower or other external heat exchanger that receives heated coolant from the data center and dissipates heat to the environment (or external cooling medium) through forced air or other means. The cooled coolant is recirculated back into the data center. The chillers and cooling towers together form a cooling facility. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In at least one embodiment, the following can be used: Figure 1An exemplary data center 100 is shown, which has a cooling system that is subjected to the improvements described herein. In at least one embodiment, many specific details are set forth to provide a thorough understanding, but the concepts herein can be practiced without one or more of these specific details. In at least one embodiment, a data center cooling system can respond to sudden high thermal demands caused by changing computing loads in today's computing components. In at least one embodiment, since these requirements experience changes from minimum to maximum values ​​of different cooling requirements or tend to change from minimum to maximum values, appropriate cooling systems must be used to meet these requirements in an economical manner. In at least one embodiment, a liquid cooling system can be used for medium to high cooling requirements. In at least one embodiment, high cooling requirements are economically met by local immersion cooling. In at least one embodiment, these different cooling requirements also reflect different thermal characteristics of the data center. In at least one embodiment, the heat generated from these components, servers, and racks is cumulatively referred to as thermal characteristics or cooling requirements because the cooling requirements must fully address the thermal characteristics.

[0054] In at least one embodiment, a data center liquid cooling system is disclosed. In at least one embodiment, the data center cooling system addresses thermal features in associated computing or data center equipment, such as in a graphics processing unit (GPU), in a switch, in a dual in-line memory module (DIMM), or in a central processing unit (CPU). In at least one embodiment, these components may be referred to herein as high thermal density computing components. In addition, in at least one embodiment, the associated computing or data center equipment may be a processing card having one or more GPUs, switches, or CPUs thereon. In at least one embodiment, each of the GPUs, switches, and CPUs may be a heat generating feature of the computing device. In at least one embodiment, the GPU, CPU, or switch may have one or more cores, and each core may be a heat generating feature.

[0055] In at least one embodiment, an intelligent in-rack pump or compressor unit may be associated with a rear door heat exchanger for a data center cooling system. In at least one embodiment, such a pump (which may be a refrigerant pump) or compressor unit may be included within a server tray or box form factor of a rack. In at least one embodiment, such a pump or compressor unit may be enabled to compress or pump a two-phase fluid for the purpose of circulation between a cold plate (such as a two-phase cold plate or a dual-cooled cold plate) and a rear door heat exchanger of the rack. In at least one embodiment, heat from an associated computing device is exchanged out of the rear door heat exchanger to a hot aisle of the data center.

[0056] In at least one embodiment, this implementation addresses limitations in cold plates that are primarily capable of supporting coolants as a fluid, such that refrigerant-based systems require external pumps, compressors, and condensing units that have limited applications. In at least one embodiment, this implementation that addresses the previous limitations uses an in-rack pump or compressor unit and uses a cold plate that is adapted for two-phase fluids. In at least one embodiment, such a system can extract heat from at least one computing device and can release such heat to a hot aisle, which enables refrigerant-based systems to be used with cold plates.

[0057] In at least one embodiment, the smart in-rack pump or compressor unit uses a two-phase refrigerant or engineered fluid, such as 7000, or Some of the engineered fluids are combined with a cold plate and a pump or compressor unit for removing heat from at least one computing device. In at least one embodiment, an intelligent in-rack pump or compressor unit using a two-phase refrigerant or engineered fluid can address the cooling needs of 100kW of heat generated. In at least one embodiment, the intelligent in-rack pump or compressor unit allows the two-phase fluid to flow directly to a two-phase cold plate having at least one evaporator therein. In at least one embodiment, an expansion valve associated with at least one cold plate or heat exchanger enables the two-phase fluid to pass through the cold plate to cause a phase change of the two-phase fluid and cause heat to be absorbed from at least one computing device. In at least one embodiment, heat from at least one computing device is absorbed into the two-phase fluid, which is then transferred to a condensing unit by a low pressure or low capacity pump or by a compressor unit. In at least one embodiment, a heat exchanger associated with the condensing unit can release at least a portion of the absorbed heat into a hot channel within the data center. In at least one embodiment, sensors such as temperature, flow, humidity, leakage, pressure, and fluid or coolant chemistry allow intelligent operation of the intelligent in-rack pump or compressor unit in the event of any problems in the auxiliary or primary cooling circuit.

[0058] In at least one embodiment, a smart in-rack pump or compressor unit can address the issues of refrigerant-based systems that require an external condensing unit. In at least one embodiment, the smart in-rack pump or compressor unit is positioned within a rack and utilizes a cold plate that is adapted for two-phase fluids, such as having microchannels for coolant flow that are different from microchannels for two-phase fluids. Thus, in at least one embodiment, no external access is required relative to the data center for cooling needs using the smart in-rack pump or compressor unit. In at least one embodiment, the smart in-rack pump or compressor unit can support the absorption of heat from at least one computing device and can cause at least a portion of the absorbed heat to be released to a hot channel, which enables the utilization of a refrigerant-based system with a cold plate.

[0059] In at least one embodiment, a smart in-rack pump or compressor unit refers to a system having at least one associated cold plate and a pump or compressor adapted to support a two-phase fluid that transitions from vapor to liquid and vice versa at different stages of operation. In at least one embodiment, a smart in-rack pump or compressor unit is capable of addressing liquid cooling of data center servers and switches with heat exchangers that have application limitations due to limited capacity to remove heat from high heat density computing components (such as GPUs / CPUs / switches). In at least one embodiment, a single-phase fluid (e.g., coolant) includes water and water with additives (including PG25 coolant), which may include such application limitations. In at least one embodiment, the thermal density of data center racks continues to increase, and innovative methods for removing heat are constantly needed while being limited to the place of existing air cooled data centers.

[0060] In at least one embodiment, the intelligent in-rack pump or compressor unit includes an associated adaptive and intelligent heat exchanger using a two-phase fluid. In at least one embodiment, the two-phase fluid may include Or other similar working two-phase fluids. In at least one embodiment, the two-phase fluid can be used for heat removal using a direct-sliced ​​two-phase cold plate with an evaporator portion. In at least one embodiment, such a cold plate can be attached to a GPU, CPU, or switch in a rack. In at least one embodiment, an associated pump (or compressor unit) of a heat exchanger utilizes a pump (or compressor) and a condensing unit to release at least a portion of the heat collected from one or more server components. In at least one embodiment, such a pump or compressor unit is placed in a rack in a form factor suitable for being located within one or more server trays and can be associated with one or more of a row of server racks. In at least one embodiment, such a pump or compressor unit can cause heat within a data center to be dissipated from a two-phase fluid flowing through a heat exchanger.

[0061] In at least one embodiment, the two-phase fluid is in a liquid-to-gas phase transition within the evaporator portion of the cold plate. In at least one embodiment, the two-phase fluid is in a gas phase when entering the compressor, but is in a fluid state of the pump. In at least one embodiment, the compressor produces high-pressure and high-temperature vapor. In at least one embodiment, the pump or compressor unit can use an associated heat exchanger to cool the vapor (or fluid) and can use a condensing unit to perform a phase change, wherein at least the vapor phase is condensed into a liquid phase or a fluid phase in the condensing unit. In at least one embodiment, this enabling feature can be by transferring the two-phase fluid to the heat exchanger of the condensing unit and providing sufficient cooling (such as forced air and surface area for heat transfer). In at least one embodiment, such a pump can be rated between 20-30 pounds per square inch (psi), and therefore the associated pipeline (including pipelines and flow controllers) can be rated five times this value (150psi). In at least one embodiment, the compressor can be rated between 150 and 200psi, and therefore the associated piping system can be rated at 1000psi. In at least one embodiment, this is done to avoid leaks in data center cooling systems with pumps or compressors within the server tray form factor of a rack. In at least one embodiment, such ductwork can be metal rather than plastic, which can be found in systems using a single-phase fluid (e.g., coolant).

[0062] In at least one embodiment, the two-phase fluid is in liquid phase when there is a pump or compressor unit and before entering the cold plate. In at least one embodiment, the two-phase fluid is transformed into a gas phase in a low pressure environment and is able to absorb heat in the evaporator portion of the cold plate. In at least one embodiment, the two-phase fluid is transformed into a vapor when it absorbs heat and is sent to a compressor or pump to circulate back to a liquid after applying pressure and releasing heat at least at a heat exchanger. In at least one embodiment, the condensing unit has a heat exchanger and a fan. In at least one embodiment, the medium (e.g., two-phase fluid) entering the heat exchanger can leave in a colder state while maintaining its phase. In at least one embodiment, such a medium entering the condensing unit can also have a phase change at its exit point. In at least one embodiment, forced air applied to a sufficient surface area of ​​the heat exchanger can achieve this phase change and support the condensing function of the heat exchanger. In at least one embodiment, similarly, the heat exchanger can be adapted to be used as a condensing unit by the exposed surface area and appropriate cooling applied thereto.

[0063] In at least one embodiment, the following can be used: Figure 1An exemplary data center 100 is shown, which has a cooling system that is subject to the improvements described herein. In at least one embodiment, the data center 100 can be one or more rooms 102 with racks 110 and auxiliary equipment to accommodate one or more servers on one or more server trays. In at least one embodiment, the data center 100 is supported by a cooling tower 104 located outside the data center 100. In at least one embodiment, the cooling tower 104 removes heat from within the data center 100 by acting on the main cooling loop 106. In at least one embodiment, a cooling distribution unit (CDU) 112 is used between the main cooling loop 106 and the second or auxiliary cooling loop 108 to enable heat to be absorbed from the second or auxiliary cooling loop 108 to the main cooling loop 106. In at least one embodiment, in one aspect, the auxiliary cooling loop 108 can access different pipes entering the server trays as needed. In at least one embodiment, the rings 106, 108 are shown as line diagrams, but ordinary technicians will recognize that one or more pipe connection features can be used. In at least one embodiment, flexible polyvinyl chloride (PVC) tubing may be used with associated piping to move fluid along each provided loop 106; 108. In at least one embodiment, one or more coolant pumps may be used to maintain a pressure differential within the coolant loops 106, 108 to enable coolant to move in accordance with temperature sensors in various locations, including in the room, in one or more racks 110, and / or in server boxes or server trays within one or more racks 110.

[0064] In at least one embodiment, the coolant in the primary cooling loop 106 and the auxiliary cooling loop 108 may be at least water and an additive. In at least one embodiment, the additive may be ethylene glycol or propylene glycol. In operation, in at least one embodiment, each of the primary cooling loop and the auxiliary cooling loop may have its own coolant. In at least one embodiment, the coolant in the auxiliary cooling loop may be dedicated to the requirements of the components in the server tray or the associated rack 110. In at least one embodiment, the CDU 112 is capable of complex control of the coolant in the provided coolant loops 106, 108 independently or simultaneously. In at least one embodiment, the CDU may be adapted to control the flow rate of the coolant so that the coolant is appropriately distributed to absorb the heat generated in the associated rack 110. In at least one embodiment, a more flexible conduit 114 is provided from the auxiliary cooling loop 108 to enter each server tray to provide coolant to the electrical and / or computing components therein.

[0065] In at least one embodiment, the ducts 118 forming part of the auxiliary cooling loop 108 may be referred to as room manifolds. Separately, in at least one embodiment, additional ducts 116 may extend from the row manifold ducts 118 and may also be part of the auxiliary cooling loop 108, but may be referred to as row manifolds. In at least one embodiment, the coolant ducts 114 enter the racks as part of the auxiliary cooling loop 108, but may be referred to as rack cooling manifolds within one or more racks. In at least one embodiment, the row manifolds 116 extend along the rows in the data center 100 to all racks. In at least one embodiment, the ducts of the auxiliary cooling loop 108, including the coolant manifolds 118, 116, and 114, may be improved by at least one embodiment herein. In at least one embodiment, a chiller 120 may be provided in the main cooling loop within the data center 102 to support cooling before the cooling tower. In at least one embodiment, for the present disclosure, additional cooling loops that may be present in the main control loop and provide cooling outside the racks and outside the auxiliary cooling loop may be together with the main cooling loop and distinct from the auxiliary cooling loop.

[0066] In at least one embodiment, in operation, heat generated within the server trays of the provided racks 110 can be transferred to coolant exiting one or more racks 110 via the flexible ducting of the row manifold 114 of the secondary cooling loop 108. In at least one embodiment, the secondary coolant (in the secondary cooling loop 108) from the CDU 112 for cooling the provided racks 110 moves toward the one or more racks 110 via the provided ducting. In at least one embodiment, the secondary coolant from the CDU 112 is transferred from one side of the room manifold with ducting 118 to one side of the racks 110 via the row manifold 116 and passes through one side of the server trays via different ducting 114. In at least one embodiment, the spent or returned secondary coolant (or secondary coolant exiting the heat carrying from the computing components) exits the other side of the server trays (such as entering the left side of the rack and exiting the right side of the rack for the server trays after circulating through the server trays or through the components on the server trays). In at least one embodiment, the spent second coolant exiting the server tray or rack 110 comes out of a different side (such as an exit side) of the duct 114 and moves to a parallel but also exiting side of the row manifold 116. In at least one embodiment, the spent second coolant moves from the row manifold 116 in a parallel portion of the room manifold 118 and travels toward the CDU 112 in an opposite direction from the incoming second coolant (which may also be refreshed second coolant).

[0067] In at least one embodiment, the spent second coolant exchanges its heat with the primary coolant in the primary cooling loop 106 through the CDU 112. In at least one embodiment, the spent second coolant may be refreshed (such as relatively cooler when compared to the temperature of the spent second coolant stage) and ready to be circulated back to one or more computing components through the secondary cooling loop 108. In at least one embodiment, various flow and temperature control features in the CDU 112 can control the heat exchanged from the spent second coolant or the flow of the second coolant into and out of the CDU 112. In at least one embodiment, the CDU 112 can also control the flow of the primary coolant in the primary cooling loop 106.

[0068] In at least one embodiment, Figure 2 The server-level features 200 shown in FIG. 1 can be associated with an intelligent in-rack pump or compressor unit of a data center cooling system. In at least one embodiment, the server-level features 200 include a server tray or box 202. In at least one embodiment, the server tray or box 202 includes a server manifold 204 intermediately coupled between provided cold plates 210A-D of the server tray or box 202 and a rack manifold of a rack hosting the server tray or box 202. In at least one embodiment, the server tray or box 202 includes one or more cold plates 210A-D associated with one or more computing or data center components or devices 220A-D.

[0069] In at least one embodiment, unlike the server-level features 200 for substantially all servers in a rack, at least one server tray or box (e.g., Figure 3 The bottom-most server tray or box 362 in the rack 302 of FIG. 360 may be designated as a control system or unit having an intelligent in-rack pump or compressor unit such that such a system may be isolated from the auxiliary cooling loop if a two-phase fluid is used. In at least one embodiment, the control system or unit in the server tray or box may include safety features (such as sensors for providing sensor data or appropriate functionality), communication features (for communicating with at least one flow controller for active mode and for communicating with an external monitor), power features (and related features thereof) for powering one or more flow controllers and at least one processor, and control features provided by at least one processor that may be associated with at least one flow controller.

[0070] In at least one embodiment, such a control unit is in the form factor of one or more server trays or boxes. In at least one embodiment, such a control unit has a pump or compressor unit to circulate a two-phase fluid through a cold plate associated with at least one computing device. In at least one embodiment, such a pump or compressor unit can circulate a two-phase fluid through a heat exchanger associated with a rear door of the rack. In at least one embodiment, the control unit within the rack is self-contained so that heat from at least one computing device is dissipated through a heat exchanger associated with the rack, which then eliminates the need for an auxiliary cooling loop.

[0071] In at least one embodiment, one or more server-level cooling loops 214A, B may be provided between the server manifold 204 and one or more cold plates 210A-D. In at least one embodiment, each server-level cooling loop 214A, 214B includes an inlet line 210 and an outlet line 212. In at least one embodiment, when there are cold plates 210A, 210B configured in series, an intermediate line 216 may be provided. In at least one embodiment, one or more cold plates 210A-D may support different ports and channels for auxiliary coolant or different fluids (such as two-phase fluids) for auxiliary cooling loops circulated from pre-loaded in-rack pumps or compressor units. In at least one embodiment, auxiliary coolant for cooling associated computing devices may be provided to the server manifold 204 via the provided inlets and outlets 206A, 206B. In at least one embodiment, a two-phase fluid for cooling may be provided to the server manifold 204 via the provided inlets and outlets 208A, 208B.

[0072] In at least one embodiment, the server tray 202 is an immersion cooled server tray that can be flooded with a fluid. In at least one embodiment, the fluid for the immersion cooled server tray can be a dielectrically designed fluid that can be used in an immersion cooled server. In at least one embodiment, an auxiliary coolant or a two-phase fluid can be used to cool the engineered fluid. In at least one embodiment, a two-phase fluid can be used to cool the engineered fluid when a primary cooling circuit associated with an auxiliary cooling circuit that circulates an auxiliary coolant fails or fails. In at least one embodiment, at least one cold plate thus has ports for an auxiliary cooling circuit and for a two-phase fluid cooling circuit, and can support a two-phase fluid cooling circuit that is activated in the event of a failure of the primary cooling circuit. In at least one embodiment, an intelligent in-rack pump or compressor unit can be used without an auxiliary cooling circuit.

[0073] In at least one embodiment, at least one dual-cooled cold plate 210B; 250 can be configured to work alongside conventional cold plates 210A, C, D. In at least one embodiment, a three-dimensional (3D) exploded view (cold plate 250) provides internal details of at least some of the features that may be included in the dual-cooled cold plate 210B. In at least one embodiment, a tear-away of a first section 250B of the cold plate 250 with microchannels 270 (also 270A) shows a different second section 250A with different microchannels 264. In at least one embodiment, a regular cold plate may have one set of microchannels 264; 270 instead of the two sets shown. In at least one embodiment, the dual-cooled cold plate 250 has different paths 264, 270 (each path also referred to as a microchannel) for an auxiliary coolant of an auxiliary cooling loop and a two-phase fluid for a two-phase fluid cooling loop. In at least one embodiment, the nature of the auxiliary coolant or the two-phase fluid may not be a dielectric. In at least one embodiment, in the use case of an immersion-cooled server, the two-phase fluid, which may be a dielectric engineered fluid, may be suitable for both cold plate applications and immersion-cooled server tray applications.

[0074] In at least one embodiment, some of the microchannels 270 are paths provided by fins 270A or other such aspects that are raised internally and perpendicular to the base of the cold plate portion 250B so that there are gaps between them for fluid or coolant flow. In at least one embodiment, some of the microchannels 264 are fluid passages in different cold plate portions 250A of the cold plate 250. In at least one embodiment, some of the microchannels 264 for two-phase fluids represent an evaporation (or evaporator) portion for the cold plate 250. In at least one embodiment, a flow controller 280 located on the inlet side of the cold plate 250 can act as an expansion valve; and this enables the two-phase fluid to enter the cold plate 250 and expand at a lower pressure, and to change phases before leaving the cold plate 250 during the absorption of heat from at least one computing device. In at least one embodiment, reference to a cold plate and its dual cooling feature may imply reference to a cold plate that can support at least two types of cooling circuits, unless otherwise stated. In at least one embodiment, both types of cold plates receive two-phase fluids for cooling, but one type can support an auxiliary cooling circuit and a two-phase fluid cooling circuit. In at least one embodiment, a standard coolant, such as facility water, may be used in the auxiliary cooling loop.

[0075] In at least one embodiment, the two-phase fluid may only support cold plate use and may not be used for immersion cooling. In at least one embodiment, each type of cold plate receives a different two-phase fluid and auxiliary coolant from a corresponding two-phase fluid cooling circuit, or an auxiliary cooling circuit or other cooling circuit that interfaces with the main cooling circuit. In at least one embodiment, where different fluids (e.g., coolants) are used with different coolant distribution units (CDUs) of different auxiliary circuits, different cooling circuits may be used with two-phase fluid cooling circuits for dual cooling cold plates, so that different channels can be used for each of the two-phase fluids and for different auxiliary coolants. In at least one embodiment, any cold plate mentioned herein is capable of operating above a dew point to prevent moisture formation, such as above 20 degrees Fahrenheit, or above a determined ambient dew point.

[0076] In at least one embodiment, the dual cooling cold plate 250 is adapted to receive two types of fluids (such as auxiliary coolant and two-phase fluid) and keep the two types of fluids different from each other via its different ports 252, 272; 268, 262 and their different paths 264, 270 (e.g., through different sections separated by gaskets and plates (e.g., in a gasket-type cold plate)). In at least one embodiment, each different path is a fluid path. In at least one embodiment, a fluid (e.g., a two-phase fluid) and an auxiliary coolant from a two-phase fluid source can be provided simultaneously to address additional cooling needs.

[0077] In at least one embodiment, the dual-cooled cold plate 250 includes ports 252, 272 to receive two-phase fluid into the cold plate 250 and to allow the two-phase fluid to flow out of the cold plate 250. In at least one embodiment, the dual-cooled cold plate 250 includes ports 268, 262 to receive auxiliary coolant into the cold plate 250 and to pass auxiliary coolant out of the cold plate 250. In at least one embodiment, the ports 252, 272 can have valve covers 254, 260 (or features of expansion valves) that can be directional and pressure controlled to enable the two-phase fluid to expand through the cold plate 250. In at least one embodiment, the valve covers can be associated with all provided ports, but the expansion valve can be dedicated to the two-phase fluid inlet. In at least one embodiment, the valve covers 254, 260 provided are mechanical features of an associated flow controller, and the mechanical features of the associated flow controller also have corresponding electronic features (e.g., at least one processor to execute instructions stored in an associated memory and control the mechanical features for the associated flow controller).

[0078] In at least one embodiment, each valve can be actuated by an electronic feature of an associated flow controller.
