DETAILED DESCRIPTION

(11) The examples and conditional language recited herein are principally intended to aid the reader in understanding the principles of the present technology and not to limit its scope to such specifically recited examples and conditions. It will be appreciated that those skilled in the art may devise various arrangements that, although not explicitly described or shown herein, nonetheless embody the principles of the present technology.

(12) Furthermore, as an aid to understanding, the following description may describe relatively simplified implementations of the present technology. As persons skilled in the art would understand, various implementations of the present technology may be of a greater complexity.

(13) In some cases, what are believed to be helpful examples of modifications to the present technology may also be set forth. This is done merely as an aid to understanding, and, again, not to define the scope or set forth the bounds of the present technology. These modifications are not an exhaustive list, and a person skilled in the art may make other modifications while nonetheless remaining within the scope of the present technology. Further, where no examples of modifications have been set forth, it should not be interpreted that no modifications are possible and/or that what is described is the sole manner of implementing that element of the present technology.

(14) Moreover, all statements herein reciting principles, aspects, and implementations of the present technology, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof, whether they are currently known or developed in the future. Thus, for example, it will be appreciated by those skilled in the art that any block diagrams herein represent conceptual views of illustrative systems embodying the principles of the present technology.

(15) With these fundamentals in place, we will now consider some non-limiting examples to illustrate various implementations of aspects of the present disclosure.

(16) FIG. 1 shows an example of an electronic device, such as a server, which may be cooled in an immersion cooling system. As shown in FIG. 1, the server 100 includes the one or more processors 102, a memory 110, a storage interface 120, and a network interface 140. These system components are interconnected via a bus 150, which may include one or more internal and/or external buses (not shown) to which the various hardware components are electronically coupled.

(17) The memory 110, which may be a random-access memory or any other type of memory, may contain data 112, an operating system 114, and one or more programs 116. The data 112 may be any data that serves as input to or output from any program on the server 100. The operating system 114 is an operating system such as MICROSOFT WINDOWS or LINUX. The programs 116 may be any programs or sets of programs that include programmed instructions that may be executed by the processors to control actions taken by the server 100.

(18) The storage interface 120 is used to connect storage devices, such as the storage device 125, to the server 100. One type of storage device 125 is a solid-state drive, which may use an integrated circuit assembly to store data persistently. Such solid-state drives are commonly used in servers, such as the server 100 as local storage, though other types of storage may also be used. The server 100 may also access storage that is physically located on a different electronic device, e.g., over a network.

(19) In some implementations, the server 100 may use well-known virtual memory techniques that allow the programs of the server 100 to behave as if they have access to a large, contiguous address space instead of access to multiple, smaller storage spaces, such as the memory 110 and the storage device 125. Therefore, while the data 112, the operating system 114, and the programs 116 are shown to reside in the memory 110, those skilled in the art will recognize that these items are not necessarily wholly contained in the memory 110 at the same time.

(20) The processors 102 may include one or more microprocessors and/or other integrated circuits, such as graphics processing units (GPUs), tensor processing units (TPUs), neural processing units (NPUs), application-specific integrated circuits (ASICs), or other special-purpose processing devices. The processors 102 execute program instructions stored in the memory 110 and/or in other memory devices (not shown) connected to or integrated with particular processors 102.

(21) The network interface 140 is used to connect the server 100 to other systems or networked devices (not shown) via a network 160. The network interface 140 may include a combination of hardware and software that allows communicating on the network 160. The software in the network interface 140 may include software that uses one or more network protocols to communicate over the network 160. For example, the network protocols may include TCP/IP (Transmission Control Protocol/Internet Protocol).

(22) It will be understood that the server 100 is merely a simplified example of such a server, and many other configurations of servers could be immersion-cooled. Further, it will be recognized that the server 100 is only one type of electronic device that could be immersion-cooled, and that many other types or configurations of electronic devices could also benefit from immersion cooling in a data center environment.

(23) FIG. 2 shows a casing 200 for use in an immersive cooling container (not shown) according to an implementation of the disclosed technology, with the direction of the immersive cooling container indicated by the arrow labeled up. The casing 200 generally has an electronic device (not shown), such as the server 100, as described with reference to FIG. 1, mounted within the casing 200. The casing 200 is mechanically configured to facilitate placement of the casing 200 (including the enclosed electronic device) into the immersive cooling container. In accordance with the disclosed technology, the casing 200 includes a casing connector 202 that is configured to couple the casing to a corresponding reservoir connector (not shown) in the immersive cooling container to provide an inlet to the casing, such that the interior of the casing 200 is in fluid communication with a reservoir (not shown) in the immersive cooling container. In some implementations, the casing 200 also includes an outlet (not shown), configured to permit the flow of heated dielectric immersion cooling liquid from the casing. In some implementations, such as the implementation shown in FIG. 2, the casing connector 202 is disposed on a bottom portion of the casing 200.

(24) Although shown in FIG. 2 as generally rectangular in shape, in some implementations, the casing connector 202 may have different shapes or forms, such as a T shape, or another shape or form having perpendicular or angled cross portions, or other shapes to accommodate fluid connections and/or stability. In some implementations, the casing connector 202 may include two or more separate connector portions, which may connect to a single reservoir or to two or more separate reservoirs. The two or more separate connector portions may also connect to a single interior portion of the casing 200 or to two or more separate interior portions of the casing 200. In some implementations, the casing connector 202 may be disposed on a different portion of the casing 200. In some implementations, the outlet may be a separate casing connector, and/or there may be two or more casing connectors disposed on portions of the casing 200.

(25) FIGS. 3 and 4 show an immersive cooling container 300 according to an implementation of the disclosed technology. FIG. 3 shows a perspective view of the immersive cooling container 300 containing no casings with electronic devices, with the direction of the immersive cooling container indicated by the arrow labeled up. The immersive cooling container 300 includes a first reservoir 302 and a second reservoir 304. In the implementation shown in FIGS. 3 and 4, a pump 306 is configured to pump heated dielectric immersion cooling liquid from the second reservoir 304 through a heat exchanger (not shown), and to pump the cooled dielectric immersion cooling liquid into the first reservoir 302. The heat exchanger may be, for example, a dry cooler or a liquid-to-liquid heat exchanger.

(26) A set of slots 308 (in FIG. 3, seven such slots 308 a shown) are configured to receive casings (not shown) containing electronic devices to be cooled. A reservoir connector 310 (e.g. a joint) is disposed at a bottom end of each of the slots 308 or on a top surface of the first reservoir 302. The reservoir connectors 310 are configured to be coupled to casing connectors (not shown) on the casings, to permit fluid communication between the first reservoir 302 and an interior of the casings. The reservoir connectors 310 may be selectively and independently open or closed. In the open configuration, a reservoir connected 310 fluidly connects the first reservoir 302 to a corresponding casing. In one embodiment, the reservoirs connectors 310 may detect a presence of a casing in their corresponding slot 308. More specifically, in said embodiment, the reservoirs connectors 310 may be communicably connected to a controller and transmit information about a presence of a casing in their corresponding slot 308. In response to a casing being detected (e.g. a casing connector being coupled to the reservoir connector 310), the controller may open the corresponding reservoir connector 310.

(27) FIG. 4 shows a front elevation view of the immersive cooling container 300, including the first reservoir 302, the second reservoir 304, the pump 306, the slots 308 (only one of which is labeled in FIG. 4, for clarity), and the reservoir connectors 310. As discussed above, the pump 306 circulates dielectric immersion cooling liquid through a heat exchanger.

(28) In FIG. 4, the immersive cooling container 300 contains casings 320 disposed in all but one of the slots 308 (i.e., six such casings have been placed in the immersive cooling container 300), and one illustrative casing 320 outside of the immersive cooling container 300. Each casing 320 houses one or more heat-generating electronic devices (not shown) to be cooled. Each casing 320 includes a casing connector (not shown), such as is shown in FIG. 2. The reservoir connectors 310 are coupled to the casing connectors of the casings in the slots 308, such that the first reservoir 302 is in fluid communication with an interior of each of the casings 320.

(29) In the implementation shown in FIG. 4, a size (i.e. length and width) of the casing connectors is smaller than a size of the corresponding reservoir connectors 310, such that the casing connectors fit within the corresponding reservoir connectors 310. A weight of the casing 320 may be used to assist the fluid connection between the interior of the casing 320 and the first reservoir 302 (e.g., such that no dielectric immersion cooling liquid flows on an exterior side of the casing 10). As shown in FIG. 4, a given immersive cooling container 300 having seven reservoir connectors 310 may provide cooling to heat-generating components disposed in seven or fewer casings 320. Reservoir connectors that are not attached to a casing may be blocked, using metal plates, self-closing mechanisms, or other means of closing or sealing a fluid connection. It will be understood that in some implementations, the size of the casing connectors may be larger than the size of the reservoir connectors, such that the reservoir connectors 310 fit within the corresponding casing connectors.

(30) In use, heat-generating electronic devices are disposed within the casings 320, each casing 320 having a fluid connection to the first reservoir 302 through a reservoir connector 310 and a casing connector (not shown). Cold dielectric immersion cooling liquid flows from the first reservoir 302 into the casings 320 and collects thermal energy from the electronic devices disposed therein. Each casing 320 defines an outlet (not shown) for outputting heated dielectric immersion cooling liquid into the second reservoir 304. The pump 306 then causes a flow of the heated dielectric immersion cooling liquid from the second reservoir 304, to the first reservoir 302. The pump 306 may be fluidly connected to a heat exchanger (e.g. a dry cooler or a liquid-to-liquid heat exchanger) to cool to dielectric immersion cooling liquid before it enters the first reservoir 302.

(31) It should therefore be understood that the casings 320 are, in use, inserted through the second reservoir 304 and in a corresponding slot 308. As such, a plurality of immersive cooling containers 300 may be stacked horizontally in a datacenter.

(32) In a system such as is shown in FIGS. 3 and 4, the fluid flows into the casings 320 through casing connectors in the bottom portions of the casings 320, and out of the casings 320 through outlets in the top portions of the casing 320. Because the heated dielectric immersion cooling liquid will rise as it collects thermal energy from the electronic devices, this corresponds to a natural flow of the dielectric immersion cooling liquid in the casings 320. The cooled dielectric immersion cooling liquid from the first reservoir 302 may rise into the casings 320, for example, due to convection, fluid pressure as heated dielectric immersion cooling liquid rises, and/or use of pumps within the casings 320.

(33) In some embodiments, the second reservoir 304 comprises a sealing chamber 350 on a lower portion thereof. The sealing chamber 350 comprises openings (not shown) aligned with the slots 308. The openings are by default in a closed configuration when no casing 320 is inserted the corresponding slot 308. As such, no dielectric immersion cooling liquid may flow in a given slot 308 if no casing 320 is inserted therein. In other words, when there are no casings 320 in the immersion cooling container 300, no dielectric immersion cooling liquid flow from the first reservoir 302 to the second reservoir 304 through the slots 308. The openings in the sealing chamber 350 enable vertical insertion of the casings 320 through the sealing chamber 350 and within the slots 308. Once the casing 320 is fluidly connected to the first reservoir 302 via a reservoir connector 310 corresponding to the slot 308 where the casing is inserted, the dielectric immersion cooling liquid may flow from the first reservoir 302 to the second reservoir 304 through said casing 320. The immersive cooling container 300 may comprise a sensor for counting a number of casings 320 in the immersive cooling container 300, the sensor being communicably connected to a controller configured to control a rotation speed of the pump 306 based on said number of casings 320. As an example, the rotation speed of the pump 306 is null in response to no casing 320 being detected. The rotation speed of the pump 306 may be increased by a pre-determined value upon an additional connected casing 320 being detected.

(34) It is contemplated that the flow of the dielectric fluid may be orentied in an opposite direction in alternative embodiments. Indeed, in another type of immersion cooling system, such as is shown in FIG. 5, the immersion cooling liquid flows over the electronic devices due to gravity. As seen in FIG. 5, which shows a cut-away schematic view of one of the casings 520 inserted into an immersive cooling container 500. The immersive cooling container 500 includes a first reservoir 502 and a second reservoir 504. The first reservoir 502 is disposed above the casing 520, and is fluidly connected to the casing 520 through a first reservoir connector 506, which configured to facilitate the flow of cooled dielectric immersion cooling liquid 530 into an inlet 522 of the casing 520. The inlet 522 may be an open top of the casing 520, or may be a connector that couples with the first reservoir connector 506, as is shown in FIG. 5. It will be understood that although the view shown in FIG. 5 shows only a single casing containing an electronic device, the immersive cooling container 500 includes numerous slots (not shown), and may contain numerous casings.

(35) A heat-generating electronic device 524 is contained within the casing 520, and a bottom portion of the casing 520 includes an outlet 526, which is configured to facilitate the flow of the dielectric immersion cooling liquid out of the casing 520, and into the second reservoir 504. In some implementations, the outlet 526 may be an opening, and the second reservoir 504 may have an open top, permitting the dielectric immersion cooling liquid to flow directly from the outlet 526 into the second reservoir 504. In some implementations, such as shown in FIG. 5, the outlet 526 may be a connector that couples with a second reservoir connector 508 to facilitate the flow of the heated dielectric immersion cooling liquid into the second reservoir 504. A pump 510 is configured to pump heated dielectric immersion cooling liquid from the second reservoir 304 through a heat exchanger (not shown), and to pump the cooled dielectric immersion cooling liquid into the first reservoir 302. The heat exchanger may be, for example, a dry cooler or a liquid-to-liquid heat exchanger.

(36) In use, either the first reservoir connector 506 or (as shown in the implementation of FIG. 5) the inlet 522 includes openings 528, through which the dielectric immersion cooling liquid 530 pours or drips onto the electronic device 524. The dielectric immersion cooling liquid 530 flows over the electronic device 524, and through the outlet 526 into the second reservoir 504. As the dielectric immersion cooling liquid 530 flows over the electronic device 524, it absorbs heat from various heat-generating components of the electronic device 524 and conveys the heat away from those components. Heated dielectric immersion cooling liquid 530 is pumped by the pump 510 from the the second reservoir 504 to the first reservoir 502. In some implementations, the pump 510 may be fluidly connected to a heat exchanger, the operation of which will generally be familiar to those of skill in the art. The heat exchanger cools the immersion cooling liquid 530 before it is pumped into the first reservoir 502.

(37) It will be understood that the first reservoir 502 may provide dielectric immersion cooling liquid to numerous casings 520, and that the second reservoir 504 may collect heated dielectric immersion cooling liquid from numerous casings 520. As in the implementations described above with reference to FIGS. 3 and 4, unused openings or connectors in the first reservoir and/or second reservoir may be covered with metal plates, blocked with a self-closing mechanism, or or blocked or closed by any other means for closing and/or sealing a fluid connection.

(38) Additionally, in some implementations, the openings 528 of the first reservoir connector 506 or the inlet 522 may include nozzles (not shown), which may be adjustable to control the flow of the dielectric immersion cooling liquid 530 from the first reservoir 502. Such nozzles may also be configured to spray or mist the dielectric immersion cooling liquid 530 onto the electronic device rather than pouring or dripping the dielectric immersion cooling liquid 530 onto the electronic device. Pressure to accommodate such spraying of the dielectric immersion cooling liquid 530 onto the electronic device may be arranged, for example, by filling the first reservoir 502 to increase the hydrostatic pressure or by pumping the dielectric immersion cooling liquid 530 through the first reservoir 502 to provide hydraulic pressure.

(39) FIGS. 6 and 7 illustrate an inmmersion cooling system in accordance with other embodiments of the present technology. More specifically, there is illustrated an immersive cooling container 600 including a first reservoir 602 and a second reservoir 604. The first reservoir 602 is disposed above lateral slots 650 (only one of which being depicted for clarity). The lateral slots 650 are formed in the immersive cooling container 600 from a lateral surface 630 thereof. In use, each lateral slot 650 may receive a casing 620 (see FIG. 7) including an electronic device to be cooled, each casing 620 being inserted through the lateral surface 630.

(40) It should be thus noted that the first reservoir 602 is sealed on an upper surface of the immersive cooling container 600. Therefore, a plurality of immersive cooling containers 600 may be vertically stacked one on top of another.

(41) As best shown on FIG. 7, each casing 620 comprises an upper casing connector 622 and a lower casing connector 626 configured to couple the casing 620 to corresponding upper and lower reservoir connectors 606, 608 respectively in the immersive cooling container 600. The upper and lower casing connectors 622, 624 may be similar to the casing connector 202 or have similar characteristics. In this embodiment, the upper and lower casing connectors 622, 624 are in a closed configuration by default (e.g. using self-closing mechanisms) such that the casing 620 may be sealed. The upper and lower casing connectors 622, 624 are actuated from the closed configuration to an open configuration in response to the casing 620 being inserted in the lateral slot 650. As an example and without limitation, the upper and lower casing connectors 622, 624 and the upper and lower reservoir connectors 606, 608 may be blind mate connectors.

(42) More specifically, the upper casing connector 622 is defined at an upper surface of the casing 620. The lower casing connector 626 is defined at a lower surface of the casing 620. As such, upon insertion of a casing 620 in a corresponding lateral slot 650, fluid connection between the casing 620 and the first reservoir is enabled by coupling of the upper casing connector 622 and the upper reservoir connector 606. Similarly, fluid connection between the casing 620 and the second reservoir is enabled by coupling of the lower casing connector 626 and the lower reservoir connector 608. For example, the upper and lower casing connectors 622, 624 may be quick-connect technology-based connectors that automatically open upon engaging the upper and lower reservoir connector 606, 608. It should therefore be understood that no dielectric fluid is present in a given slot 650 when no casing 620 is present in said given slot 650. Fluid communications between the casing 620 and the upper and lower reservoirs 602, 604 occurs in response to the casing 620 being inserted in a given slot 650. In other words, the upper casing connector 622 provides an inlet to the casing 620, such that an interior of the casing 620 is in fluid communication with the first reservoir 602. Similarly, the casing 620 also lower casing connector 626 provides an outlet configured to permit the flow of heated dielectric immersion cooling liquid from the casing 620 to the second reservoir 604.

(43) A pump 610 is configured to pump heated dielectric immersion cooling liquid from the second reservoir 604 through a heat exchanger (not shown), and to pump the cooled dielectric immersion cooling liquid into the first reservoir 602. The heat exchanger may be, for example, a dry cooler or a liquid-to-liquid heat exchanger. A nozzle 640 may spay the cooled dielectric immersion cooling liquid in the first reservoir 602. In alternative embodiments, the pump 610 may pump the dielectric immersion cooling fluid from the first reservoir 602 through said heat exchanger and into the second reservoir 604. In other words, a direction of a flow of the dielectric immersion cooling fluid in said alternative embodiments is opposed to the direction of the flow of the dielectric immersion cooling fluid as depicted in FIGS. 6 and 7.

(44) In at least one embodiment, the upper and lower reservoir connectors 606, 608 may be communicably connected with a controller, such as controller 800 (see FIG. 8), that receives information about a presence of a casing 620 in a slot 650 corresponding to said upper and lower reservoir connectors 606, 608. The upper and lower reservoir connectors 310 may be selectively and independently open or closed by said controller. In response to receiving from both of the upper and lower reservoir connectors 606, 608 information indicative of a presence of the casing 620 in the corresponding slot 650, the controller may actuate the upper and lower reservoir connectors 606, 608 to be open and thus let the cooled dielectric immersion cooling liquid flow from the first reservoir 602 to the second reservoir 604 through the casing 620. In parallel to opening the cooled dielectric immersion cooling liquid, the controller may adjust a rotation speed of the pump 610 such that a flow of the dielectric immersion cooling liquid is adapted to a number of casing 620 present in the immersive cooling container 600. For instance, if a new casing 620 is detected in a given slot 605, the controller may cause the rotation speed of the pump 610 to increase.

(45) Moreover, in response to receiving from both of the upper and lower reservoir connectors 606, 608 information indicative of an absence of casing 620 in the corresponding slot 650, the controller may actuate the upper and lower reservoir connectors 606, 608 to be closed. In parallel to closing the upper and lower reservoir connectors 606, 608, the controller may cause the rotation speed of the pump 610 to decrease. As an example, a rotation speed of the pump 610 when no casing 620 is present in the immersive cooling container 600 is null.

(46) FIG. 8 is a schematic block diagram of a controller 800 of immersive cooling containers disclosed herein according to an embodiment of the present technology. The controller 800 comprises a processor or a plurality of cooperating processors (represented as a processor 810 for simplicity), a memory device or a plurality of memory devices (represented as a memory device 830 for simplicity), and an input/output interface 820 allowing the controller 800 to communicate with components of the immersive cooling containers. The processor 810 is operatively connected to the memory device 830 and to the input/output interface 820. The memory device 830 includes a storage for storing parameters 832, including for example and without limitation pre-determined rotation speeds of a pump of the immersive cooling container according to a number of casings present in the immersive cooling container. The memory device 830 may comprise a non-transitory computer-readable medium for storing code instructions 834 that are executable by the processor 810 to allow the controller 800 to perform the various tasks allocated to the controller 800.

(47) The controller 800, upon being implemented to control operations of the immersive cooling container 600, is operatively connected, via the input/output interface 820, to the pump 610, the upper reservoir connectors 606 and lower reservoir connectors 608. The controller 800 executes the instructions 834 stored in the memory device 830 to implement the various above-described functions that may be present in an embodiment. FIG. 8 as illustrated represents a non-limiting embodiment of the controller 800. This particular embodiment is not meant to limit the present disclosure and is provided for illustration purposes.

(48) It will be understood that, although the embodiments and/or implementations presented herein have been described with reference to specific features and structures, various modifications and combinations may be made without departing from the disclosure. For example, it is contemplated that in some implementations, the features described above may be used in different arrangements, or in other combinations. The specification and drawings are, accordingly, to be regarded simply as an illustration of the discussed implementations or embodiments and their principles as defined by the appended claims, and are contemplated to cover any and all modifications, variations, combinations or equivalents that fall within the scope of the present disclosure.
