It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not necessarily restrictive of the invention as claimed. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention, and, together with the general description, serve to explain the principles of the invention.
The numerous advantages of the disclosure may be better understood by those skilled in the art by reference to the accompanying figures.
Reference will now be made in detail to the subject matter disclosed, which is illustrated in the accompanying drawings.
Power skids, in general, include a floor constructed to support equipment, such as electrical power distribution and/or back-up power equipment for data centers. Power skids may be modular and installed in the whitespace of a data center, such as in raised floor whitespace using Raised Floor Power Skids (RFPSs).
Conventional power skids have either a minimal floor structure where the floor of the power skid is placed directly on the ground or a raised floor power skid structure with an open design without side-walls, having a supporting structural frame that allows air movement both under the power skid and up through the power skid to cool equipment.
Installing a power skid in an existing or newly constructed data center that has a raised floor has a unique set of challenges. It is contemplated herein that these challenges may include how to cool the equipment mounted on the power skid, how to cable the equipment, and how to place equipment in a serviceability line-up that maintains National Electrical Code (NEC) required work clearances.
Accordingly, the present disclosure is directed to a raised floor power skid with an enclosed design that addresses at least some of these challenges. For example, the power skid may be configured to enclose (e.g., at least partially enclose) a volume with side walls so that cool air travelling below a raised floor whitespace is blocked from entering below the power skid floor and is deflected upward to efficiently cool the equipment above the power skid. Moreover, the present disclosure is directed to a RFPS that simplifies and improves how equipment is cooled, installed, and serviced. In some embodiments, the present disclosure fills a desire for power skids configured to be installed in specific, existing whitespace. Such existing whitespace may require particular design constraints and requirements. Benefits of such a power skid may include lower installation costs and longer-term operational efficiencies.
The enclosing elements 106 may, as shown, be disposed along a boundary 108 (e.g., rectangular boundary) and coupled to the support structure (e.g., support structure 306 of
The power skid 102 includes a floor 104 on top of the support structure 306 (see
As noted, the power skid may include one or more enclosing elements 106 (e.g., side enclosures, side walls, and the like). For example, the side walls 106 may be multiple flat sheets of a material. For instance, the side walls 106 may be 1/16 inch thick and may be steel sheets. The side walls 106 may at least partially enclose a volume of air which can be a space for equipment cables. The side walls 106 may line up with vertical supports for ease of coupling (e.g., coupling via mechanical fasteners and/or welding).
The power skid 102 may be configured to allow for clear, unobstructed access under the power skid floor 104 (i.e., access to components in the volume 310 shown in
It is noted that the specific thicknesses, relative sizes, materials, and the like shown in
In embodiments, the power skid 102 may be configured such that at least some of the equipment 202 is facing outwards. For example, the equipment 202 may be conveniently accessible by a user standing just outside the power skid 102. Such a configuration may allow for efficient cooling by cool air being directed to the equipment 202 that is facing outwards.
The power skid 102 includes support structure 306, such as metal cross links and the like in a raised floor configuration such that the floor 104 is configured to be used in a raised floor environment.
In some embodiments, the power skid 102 includes cable openings 308, such as holes cut into the floor 104. The cable openings 308 allow for cables 304 to be coupled (e.g., electrically and physically coupled) to the equipment 202. For example, the cable openings 308 may be aligned to be inside a footprint of the equipment 202.
Benefits of the present disclosure may include a power skid 102 configured to integrate with existing (e.g., specific) raised floor configurations and a corresponding cooling methodology of those raised floor configurations—while helping to mitigate a variety of challenges in doing so.
For example, the power skid 102 may be configured to integrate with an existing raised floor cooling configuration, such as via openings and/or ducts configured to direct air that is below the raised floor above the raised floor and towards the equipment 202. The power skid 102 may simplify power skid deployment (e.g., whitespace power skid installation) by being compatible with existing cooling configurations of a data center. For instance, users may be able to apply cooling to a power skid 102 and mounted equipment 202 on the power skid 102 due to integration with an existing cooling configuration, thereby reducing cost, speeding up design/installation, improving efficiency, and/or improving cooling performance. The power skid 102 may prevent the cooled air from inefficiently cooling the cables 304 and portions (e.g., trays 302) of the power skid 102 adjacent to the cables 304.
The power skid 102 may allow for improved overall air management and may perform and function like an air deflector (e.g., directing air to the equipment 202 on the power skid 102 and treating the equipment 202 as a zone to be directly cooled). For example, the one or more enclosing elements 106 and the floor 104 may help direct cooled air to the equipment 202 The enclosing elements 106 and the floor 104 may prevent cool air from inefficiently flowing under the power skid floor 104, providing energy efficiency savings.
Due to less extreme temperatures, the power skid 102 may allow for use of standard type electrical power cables in lieu of plenum rated cables. For example, the power skid 102 may allow for standard Diesel Locomotive Cables (DLO) and not require thicker and better temperature-rated electrical power cables (e.g., plenum rated or Metal Clad (MC) cables) that are typically required in conventional power skids. This may save material costs, and also simplify installation as higher rated cables may not have a bend radius that accommodates the same footprint as standard type electrical power cables. Thus, labor may be significantly reduced in routing and forming the power cables between the equipment lineups on the power skid 102.
In some typical whitespace cooling configuration data centers, cool air may flow under the raised floors 404. In embodiments of the present disclosure, the addition of the enclosing elements 106 prevents the cool air 406 from inefficiently cooling the underside of the power skid floor 104. For example, the opening 402 may allow/direct the cool air 406 to raise above the floor 104 to cool equipment 202 as shown in
The opening 402 may be any opening (e.g., one or more openings 402 along one or more sides of the power skid such as along all four boundaries 108). The cool air 406 may be directed to the equipment 202 through any method or element. For example, the opening 402 may be proximate to the edge of the power skid 102 and defined by the adjacent raised floor 404 of the whitespace and/or defined by the power skid 102. For example, the opening 402 may be built into the adjacent floor 404 and/or built into (e.g., designed) as part of the power skid 102. The opening 402 may be any shape (e.g., large opening, slots, holes/perforations, and the like). The opening 402 may include deflecting surfaces (not shown) to direct the cool air 406 towards the equipment 202 (e.g., at an angle relative to the floor 104). The deflecting surfaces may be located above and/or below the floor 104. For instance, the deflecting surfaces may be enclosed ducts or surfaces of individual vents openings 402. By way of another example, enclosed ducts (e.g., air hoses, solid ducts, and the like) may be run from the opening 402 to the equipment 202 directly (e.g., to an equipment opening near the top of the equipment 202) to efficiently direct the air 406 to the equipment 202. The opening 402 may include (or be configured to work with) one or more active air flow regulators (not shown) (e.g., to regulate the amount of air 406). The air flow regulators (e.g., pump, fan, and the like) may actively force/push air 406 through the opening 402 and/or actively/passively constrain the amount of air 406 pushed through the opening (e.g., using dynamically adjustable vents, flaps, valves, and the like) and be located proximate to or far from the opening 402.
It is contemplated that such an opening 402 may allow for unobstructed corridor space (e.g., corridor space 804 of
The power skid 102 may include tray support elements 408 configured to support the trays 302 that are supporting the cables 304.
In embodiments, the tray support elements 408 are any elements configured to support the trays 302, such as, but not necessarily limited to, threaded rods and channels coupled to cross beams and the like, which are vertically aligned and are also coupled to the trays 302.
For example, cable openings (e.g., holes) in the floor 104 of the power skid 102 may be located in a configuration such that equipment 202 installed will be facing outwards.
The power skid 102 may include shared corridor space 804 for switchgear equipment requirements on a single skid, which may also improve servicing of the equipment 202.
Referring back to
The power skid 102 and equipment 202 may be pre-wired (e.g., at the factory, before installation, and the like), which may save installation costs and shorten onsite installation time.
The power skid 102 may be configured to be installed (e.g., via field installation in a data center) so as to not impede nor obstruct underfloor circuits such as utility cables, generator cables, output circuits to the batteries, PDUs, power circuits, control cabling and/or the like. For example, the power skid may be configured to be placed as such (e.g., by design), such as outer size dimensions providing needed clearance.
The power skid 102 may be configured to be fabricated (welded, mechanically fastened, and the like) from metal, such as steel.
In a general sense, those skilled in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary.
The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.
