Technical Field

The present disclosure relates generally to rack-mounted liquid cooled electronic equipment, and in particular, to management of cables and flexible tubing for rack-mounted liquid cooled electronic equipment.

Background

Large computing facilities strive to keep up with the market demand for increased processing resources. Thus, such facilities may implement a large number of rack systems configured to support thousands or even tens of thousands of electronic processing components to accommodate market demand.

It should be appreciated that so many rack-mounted electronic processing assemblies consume a significant amount of power and, in turn, generate a significant amount of heat that needs to be controlled to ensure proper processing performance. Various heat dissipation measures, such as, for example, liquid cooling techniques, have been implemented to cool rack-mounted electronic processing assemblies to acceptable ambient temperature levels.

Thus, in addition to power and communication cables, rack systems must also house associated flexible liquid cooling tubing that run to and from each of the rack-mounted electronic processing assemblies. During racking and destacking maintenance operations, the combined cable and conduit bundles for each of the repaired racking electronic processing assemblies often become difficult to operate and manage. Therefore, there is interest in managing bundles of cables/pipes for rack-mounted liquid cooled electronic assemblies.

With these basic principles in place, non-limiting embodiments have heretofore been presented that illustrate various aspects and implementations of the present disclosure.

In particular, fig. 1A and 1B depict a cross-sectional view and a perspective view, respectively, of a rack-mounted submersible housing in a racking position for use with an articulating scissor cable/duct management structure in accordance with an embodiment of the present disclosure. The racking position of the submerged housing 104 is applied during installation and real-time operation.

For ease of illustration and understanding only, the figures depict a single rack-mounted immersion housing 104 within the rack system 100. This description should not be construed as limiting, as the inventive concepts presented herein encompass and contemplate the use of multiple immersion shells 104 accommodated by the rack system 100.

As shown, rack system 100 includes a rack frame 102, rack frame 102 housing a rack-mounted liquid cooled housing 104 that includes at least one electronic component 106. As described in detail below, liquid cooling techniques for reducing the temperature of at least one electronic assembly 106 or electronic components thereof may include using an immersed dielectric cooling fluid, using directed circulated cooling of water and water blocks disposed directly on the electronic components, or some combination of the two techniques. For maneuverability purposes, the specification refers to the rack-mounted liquid cooled housing as an immersed housing 104, but it should be understood that this term is not limiting in any way.

As depicted, the submerged housing 104 presents a generally "book-like" rectangular shape, with the submerged housing 104 slidably inserted and mounted within the rack frame 102 of the rack system 100 in the racking position. The immersion housing 104 may be configured to include at least one immersion electronic assembly 106 completely immersed in a dielectric cooling fluid, wherein the at least one immersion electronic assembly includes various heat-treating components 108.

In some implementations, the submerged housing 104 may be configured to include a serpentine convective coil 110 immersed in a dielectric fluid. The serpentine convective coil 110 is configured to cool the ambient temperature of the dielectric cooling fluid caused by the heat-generating processing component 108 by thermal convection.

In some implementations, the submerged housing 104 may be configured to include a closed loop cooling water distribution device configured to circulate cooled, directed water via a flexible piping network, through the serpentine convective coil 110, and through liquid cooling blocks that are directly thermally coupled to the processing component 108.

The cables providing power and communication facilities to the immersion electronic processing assembly 106 and the flexible tubing leading to the cooled water are combined together to form a bundle 114 of cables/tubing for use with the respective immersion housing 104. The path (routing) of the bundles 114 of cables/conduits to the respective immersible shells 104 is accommodated via an opening in the rack frame 102.

As shown, the back plate 104B of the immersion housing 104 includes contact points 116 of the immersion housing and the back plate 102B of the rack frame 102 includes contact points 118 of the rack frame. As discussed in detail below, these contact points 116, 118 operate to engage complementary elements of the articulating scissor cable/conduit arrangement 112 that manage the bundle 114 of cables/conduits. As such, the contact point portion 116 of the immersion housing and the contact point portion 118 of the rack frame may include protrusions, bumps, rods, apertures, or the like to detachably mate with complementary elements of the articulating scissor cable/duct structure 112.

As shown, when the submerged housing 104 is in the racking position, there is a fixed lateral distance separation between the back plate 104B of the submerged housing 104 and the back plate 102B of the rack frame 102. This fixed lateral distance spacing defines a racking space. The drop booth is configured to house the outer shell of the bundle 114 of cables/pipes of the respective submerged housing 104 when the submerged housing 104 is in the racking position. To manage the bundles 114 of cables/pipes of the respective submerged housings 104, an articulated scissor type cable/pipe structure 112 is proposed. The articulating scissor type cable/duct structure 112 is configured to support and guide the bundles 114 of cables/ducts into the overhead room and maintain orderly control of the bundles 114 of cables/ducts.

Fig. 3A depicts a perspective view of features of one of the arms of the articulating scissor cable/conduit structure 112, in accordance with an embodiment of the present disclosure. For simplicity, only the first arm 112A is depicted. It should be appreciated that the structural features of the first arm 112A are also joined by the second arm 112B in a complementary mirror image manner for the construction of the scissor cable/duct structure 112.

As shown in fig. 3A, the first arm 112A includes a flat surface portion 112A-1 configured to receive and house the bundle 114 of cables/conduits and a retaining sidewall portion 112A-2 configured to limit the bundle 114 of cables/conduits from protruding laterally. The first arm 112A further includes an engagement portion 112C, which engagement portion 112C is configured to hingedly mate with an engagement portion of the second arm 112B of the scissor cable/conduit structure 112 via the central axle 112D. The engagement portion 112C may also include a flexible spring structure (not shown) to bias the arms 112A, 112B toward each other or to bias the arms 112A, 112B away from each other. The first arm 112A also includes a fastener 112A-3 disposed at a top thereof, and the first arm 112A is configured to be detachably connected to the back plate 104B (i.e., the contact point portion 116) of the immersion housing.

The articulating scissor type cable/conduit structure 112 may be made of metal, plastic, rubber, or any other suitable material. Further, the articulating scissor type cable/conduit structure 112 may be configured as a unitary component that is shaped, pressed, or molded. Alternatively, the articulating scissor type cable/conduit structure 112 may be configured as a combined assembly of individual components.

Fig. 3B depicts a side view of the articulating scissor cable/conduit structure 112 for the submerged housing 104 in a partially destacked position in accordance with embodiments of the present disclosure. As shown, the articulating scissor cable/conduit structure 112 includes a first arm 112A, a second arm 112B, and an engagement portion 112C that includes a central shaft 112D. By providing a central pivot point, the engagement portion 112C is configured to couple the first and second arms 112A, 112B together while enabling the arms 112A, 112B to rotatably move relative to one another in a vertically hinged manner as the submerged housing 104 moves between the racking position and the destacking position. As will be discussed in further detail below, the engagement portion 112C is also configured to controllably direct the bundle of cables/conduits 114 about a pivot point during movement of the destacking and racking operations to maintain at least a desired flow rate of the directed cooled fluid flowing through the conduits in the bundle of cables/conduits 114.

The articulating scissor cable/conduit structure 112 is designed to operate in a "scissor" fashion, wherein the arms 112A, 112B are configured to extend laterally outwardly away from each other and articulate the engagement portion 112C in a vertically upward direction during a destacking operation. Correspondingly, during a racking operation, the arms 112A, 112B are also configured to retract laterally inward toward each other and hinge the engagement portion 112C in a vertically downward direction.

As shown in fig. 3B, the first arm 112A includes a fastener 112A-3 disposed at a top thereof and is configured to be removably connected to or mate with the back plate 104B of the immersion housing (i.e., the contact point portion 116). The second arm 112B includes a fastener 112B-3 disposed at a top thereof and is configured to be removably connected to or mate with the back plate 102B of the rack frame (i.e., the contact point portion 118). The fasteners 112A-3, 112B-3 may include hooks, snaps, clasps, latches, clamps, grommets, snaps, or other suitable components that may be easily attached to and detached from the respective contact points 116, 118 of the back plate of the immersion housing and the back plate of the rack frame.

Returning to fig. 1A, 1B, when the submerged housing 104 is in the racking position, the hinged scissor type cable/duct structure 112 supports the bundles 114 of cables/ducts and guides the bundles 114 of cables/ducts into a fixed racking space. Specifically, during a racking operation, a first arm 112A of the articulating scissor cable/duct structure 112 that engages a contact point 116 of the back plate of the immersive housing via the fastener 112A-3 is urged toward a second arm 112B that engages a contact point 118 of the back plate of the rack frame via the fastener 12B-3. As a result, the engagement portions 112C hinge in a vertically downward direction to contract the lateral distance between the back plate 102B of the respective immersion housing 104 and the back plate 104B of the rack frame 102, thereby supporting the bundles 114 of cables/pipes and guiding the bundles 114 of cables/pipes orderly into the fixed racking space.

Fig. 2A and 2B depict a cross-sectional view and a perspective view, respectively, of a rack-mounted submersible housing in an destacking position for use with an articulating scissor cable/conduit management structure in accordance with an embodiment of the present disclosure. The destacked position of the submerged housing 104 is used during, for example, maintenance, repair, testing, etc. Since fig. 2A, 2B show the same structural features as fig. 1A, 1B, the same reference numerals are used and the previous description of these features and attributes is omitted for the sake of brevity.

As shown in fig. 2A, 2B, in the destacking position, the submerged housing 104 is slidably removed from the rack frame 102. In the destacking position, the lateral distance separation between the back plate 104B of the immersion housing and the back plate 102B of the rack frame defines an adjustable destacking space that is greater than the destacking space. That is, the variability of the lateral distance spacing of the destacking space is directly related to the extent to which the submerged housing is slidably removed from the rack frame 102.

As described above, the articulating scissor cable/conduit structure 112 is designed to operate in a "scissor" fashion. Thus, for the destacking operation, the first arm 112A of the articulating scissor cable/duct structure 112 that engages the contact point 116 of the back plate of the immersive housing via the fastener 112A-3 is pulled separately away from the second arm 112B that correspondingly engages the contact point 118 of the back plate of the rack frame via the fastener 112B-3. As a result, the engagement portions 112C are hinged in a vertically upward direction to lengthen the lateral distance separation between the back plate 104B of the respective immersible shell 104 and the back plate 102B of the rack frame 102, thereby supporting the bundles 114 of cables/conduits and sequentially guiding the bundles 114 of cables/conduits through the adjustable racking space.

In the event that the immersion housing 104 must be completely removed from the rack frame 102 due to, for example, equipment failure/malfunction, upgrade replacement, etc., the hinged scissor type cable/tube structure 112 can be easily separated from the back plate of the respective immersion housing 104 or from the back plate 102B of the rack frame 102 by the detachable fasteners 112A-3, 112B-3.

As described above, the engagement portion 112C is also configured to guide the bundle 114 of cables/pipes in a controlled manner about the engagement portion 112C pivot point during movement of the destacking and racking operations. To this end, fig. 4-6 illustrate an engagement portion 112C pivot point control configuration of a bundle 114 of cables/conduits according to various embodiments of the present disclosure. For clarity and ease of handling, some features of the engagement portion 112C and the bundle of cables/conduits 114 have been omitted from the figures and the description will be focused on the conduits in the bundle of cables/conduits that provide a directed circulated fluid through the conduits, it being understood that such description applies equally to the cables in the bundle of cables/conduits 114.

Thus, fig. 4 depicts a configuration of an embodiment of the engagement portion 112C, the engagement portion 112C guiding the bundle 114 of cables/pipes in a controlled manner about the engagement portion 112C pivot point. As shown, the engagement portion 112C provides the following arrangement: this arrangement enables the bundles 114 of cables/conduits to be orderly wrapped and wound around the central shaft 112D.

In this arrangement, the loop of cable/conduit bundles 114 wrapped around the central axis 112D is arranged with sufficient space and flexibility to enable various movements of the submerged housing 104 during the cable/conduit bundles destacking and racking operations. This arrangement also prevents any undesired bending or curling to maintain the desired flow rate of the directed circulated cooling fluid flowing through the tubes in bundle 114 during the movements of the destacking and racking operations.

Fig. 5 depicts an embodiment of a control configuration of the further engagement portion 112C of the bundle 114 of cables/conduits, the further engagement portion 112C being controllably directed around the engagement portion 112C pivot point to the bundle of cables/conduits. As shown, the engagement portion 112C controls the configuration to include a pair 504 of rotatable coupling elements for use with the bundle 114 of cables/pipes about the 112C pivot point to facilitate movement of the destacking and racking operations.

Specifically, the engagement portion 112C controls a configuration including a pair 504 of rotatable coupling elements disposed proximate the central shaft 112D. Each of the rotatable coupling elements 502 of the pair 504 presents an elbow or "L-shaped" profile having a first end and a vertically oriented second end, wherein each of the first and second ends includes a sealed, rotatable, press-fit connection, such as, for example, a hydraulic fitting, a pneumatic fitting, or any similar coupling fitting.

As shown, each pair 504 of rotatable coupling elements is arranged for use with a single tube in the bundle 114 of cables/tubes. In this arrangement, a first end of the first coupling element 502 in the pair 504 is matingly connected to a conduit extending from the back plate 102B of the rack frame. The rotatable second end of the first coupling element 502 is configured to interact with the rotatable second end of the second coupling element 502 of the corresponding pair 504. Further, the first end of the second coupling element 502 is matingly connected to a conduit extending toward the back plate 104B of the immersive housing.

In an implementation, portions of the coupling element 502 may be attached to respective arms 112A, 112B of the scissor cable/duct structure 112, or portions of the coupling element 502 may be rotatably attached to the central shaft 112D.

With this arrangement, each pair 504 of rotatable coupling elements for use with the tubes in the bundle 114 of cables/tubes facilitates movement during the destacking and racking operations by employing coupling elements 502, the coupling elements 502 allowing rotation in a controlled manner in response to various movements caused by the destacking and racking operations. In this way, this arrangement prevents any undesired bending or curling to maintain a desired flow rate of the directed circulated cooling fluid flowing through the tubes in bundle 114 during the destacking and racking operations movements.

Fig. 6 depicts an embodiment of a control configuration of another engagement portion 112C of a bundle 114 of cables/conduits. As shown, the engagement portion 112C controls the configuration to include a pair of flexible restraint fittings 602 for use with the cable/tube bundle 114 about the 112C pivot point to facilitate movement of the destacking and racking operations.

Specifically, the engagement portion 112C controls the configuration to include a pair of flexible strain relief fittings 602 disposed proximate the central shaft 112D. Each of the respective flexible strain relief fittings 602 presents an elbow or "L-shaped" profile having a first end and a vertically oriented second end. The flexible strain relief fitting 602 comprises a flexible material capable of accommodating the contraction, extension, and torsion motions provided by the fitting 602 of one or more conduits.

As shown, each flexible strain relief fitting 602 is arranged for use with one or more conduits in the bundle 114 of cables/conduits. In this arrangement, a first end of the first flexible strain relief fitting 602 is configured to receive one or more conduits of the bundle 114 of cables/conduits extending from the back plate 102B of the rack frame. The second end of the first fitting 602 is configured to orient one or more conduits vertically to guide the one or more conduits to a complementary second end of the second flexible strain relief fitting 602. Further, the second end of the second flexible strain relief fitting 602 is configured to receive one or more conduits and vertically redirect the received one or more conduits for extension toward the immersive housing backplate 104B.

In implementations, the strain relief fitting 602 may be attached to the respective arms 112A, 112B of the scissor cable/duct structure 112, the strain relief fitting 602 may be rotatably attached to the central shaft 112D, and/or the strain relief fitting 602 may be wrapped around the central shaft 112D.

With this arrangement, each of the flexible strain relief fittings 602 for one or more of the bundles 114 of cables/conduits facilitates various movements during the destacking and racking operations by employing a pliable flexible member that controllably allows for various contraction, extension, and torsion movements of the one or more conduits during the destacking and racking operations. In this way, this arrangement prevents any undesired bending or curling to maintain a desired flow rate of the directed circulated cooling fluid flowing through the tubes in bundle 114 during the destacking and racking operations.

As described above, it should be understood that although the embodiments described herein have been described with reference to particular features and structures, various modifications and combinations can be made without departing from the basic concepts and principles taught by these disclosures. The description and drawings should therefore be regarded as providing heuristic guidance regarding the basic concepts and principles presented by the implementations and embodiments.

Therefore, the scope of coverage of the basic concepts and principles presented by the disclosed implementations and embodiments is defined by the appended claims and is contemplated to cover any and all modifications, variations, combinations, or equivalents that fall within the scope of the disclosure.
