FIELD OF THE INVENTION
The present disclosure relates to a computer server rack and more particularly, a computer server rack system that can be used to efficiently direct air flow to electric equipment such as servers and other network devices for dissipation of heat.
BACKGROUND
Existing rack-mount server systems include a server rack and a plurality of server units received in the server rack. Typically each of the server units is mounted to the server rack with a pair of mounting brackets or rails respectively fixed to the inside surface of opposite sidewalls of a server rack. There have been numerous efforts to direct air and other fluids to electronic equipment to aid in heat dissipation.
SUMMARY
The server rack according to the invention includes a frame that includes hollow tubular support posts on the front sides and rear sides of the device. Between the front and rear posts are forward side panels and rearward side panels. The panels receive a complement of cartridges that have valve members to control the flow of air from a rear cavity though passages in the cartridges, through the rail and into servers. A plurality of side rails for receiving servers are attached to the front and rear posts. The rails have passages through the sidewalls that correspond with passages provided on the sidewalls of the servers.
In a preferred embodiment, air conditioned air is introduced to forward side panels through passages provided on the upper and lower surfaces. Next, air travels from the forward panel, though one or more passages that is provided through a cartridge member, and then, into a front section of a server through a passage that is provided on the lateral sidewall of the server. Air travels through the server from the front section of the server to a rear section and then exits through a passage in the lateral sidewall to a cartridge that is provided in a rear panel. Next the air is returned to the air conditioner unit for recirculation.
In an embodiment the sever rack is approximately 6 feet tall and designed to accommodate forty-two server units in 4.445 cm (1.75 inch) increments. Rail members are provided at each unit segment on the side panels and support a server. In embodiments further discussed below, passages through the cartridges have at least one valve member that can be individually electromechanically or manually controlled. When no server is provided in a specific rack unit, or when the temperature is otherwise adequately controlled in a particular server unit, the aperture may be closed. In embodiments, a controller automatically opens or closes valve members provide in cartridges in response to a signal from a thermometer.
As such, it should be appreciated that the valves or passages can be opened and closed variably for each server depending on the cooling needs for the server. Further, as discussed herein, the degree of air flow through the aperture can be controlled using a damper or weir arrangement. Therefore, in embodiments, a local controller is provided and can receive input information from thermometers reading the temperatures of the servers and can adjust the opening and closing valves aperture accordingly. Alternatively the dampers may be manually adjusted. In yet further embodiments a central controller receives signals from a plurality of server racks.
Each of the openings on the post is provided with a releasable seal to block flow depending on the particular configuration of servers. In embodiments, flexible manifolds extend from the posts to direct the fluid to and from access areas provided on the servers. While the preferred embodiment contemplates the use of air flow, in embodiments the frame is configured to receive a liquid and the posts and manifold direct fluid to heat exchange elements that engaged the respective servers.
In yet further embodiments the rack is configured to allow both liquid flow and air flow.
These aspects of the invention are not meant to be exclusive. Furthermore, some features may apply to certain versions of the invention, but not others. Other features, aspects, and advantages of the present invention will be readily apparent to those of ordinary skill in the art when read in conjunction with the following description, and accompanying drawings.

Upon release of the lever, the pins may be received in opposite openings provided on the side panel members to retain the cartridge members in place.
In FIG. 43A, blocking member 4330 is depicted retained within opposite grooves 4351 and 4352 provided in the interior top surface 4371 and bottom interior surface 4372 of the cartridge 2166 and engaged to allow for movement within the grooves.
FIG. 43B depicts a sectional view of rack assembly invention 1000. Void region 2159 is defined between a cartridge assembly 2166 and planar sheet member of panel section 1210 through which air flows into the rear of cartridge 2166. The cartridge includes a top sealing member 4370 that is comprised of a resilient material which is provided to assist with forming a seal with an adjacent cartridge. The air flow is interfered by member 4330 which will slide to open and close a passage 4120 that allows air flow to server 305. The rail member is depicted as two part member 307 and 308 through which is provided with a passage to allow for air flow from cartridge 2166 to server 305.
FIG. 43C depicts a further embodiment that include annular seal ring member 4398. In this embodiment an annular fabric shroud 4399 will axially extend from the annular ring 4398 provided at the junction of air passages and, in response to air flow, shroud 4399 is radially displaced to seal the junction between the components. As such when air flows, the shroud fills the gap between the cartridge 2166, rail members 307 and 308, and server 305.
FIG. 43D schematically depicts air flow from server 305 to a rear panel. Like the embodiment depicted in FIG. 43C, the embodiment includes annular seal member 3488 and shroud member 4389 that, in response to air flow is displaced to minimize the air loss through the interface between server 305, rail members 307 and 308 and cartridge 2166.
FIG. 44 depicts cartridge 2166 wherein the blocking member 4330 has been moved to close the passages 4120 and the pins 1310 are depicted in a retracted position. In embodiments, the seal is mechanically lifted by rotation of a cam member that alternatively lowers and raises a seal member such as seal member 4370. In yet alternative embodiments, the resilient seal member 4370 is spring biased and can be displaced downwardly upon assembly. In yet further embodiments, a mechanical switch is provided that lifts and mechanically locks the resilient member by lateral movement of a switch extension that is accessible through an L shaped opening.
FIG. 45 illustrates a side panel assembly 1210 including a plurality of cartridges such as cartridges 2166 that span upright member 2630 and upright member 2631. The rear surface of the cartridges define a front surface of an internal cavity of the panel. Adjacent to upright member 2630 is an upright front post member 2482 that is provided to support the servers and rails of the device.
FIG. 46 depicts a completely assembled forward panel including upright front post upright member 2482, section and cartridges such as 2166 placed between the section vertical supports 2630, 2631.
FIG. 47 depicts an alternative assembly that includes a number of cartridges 4720 that are devoid of valves and passages.
FIG. 48 depicts a further alternative assembly where the cartridges that were selected include no valves or passages. Thus FIGS. 47 and 48 illustrate alternative configurations of cartridges 2166 and blanks 4720 that may be used with the invention.
As best seen in FIG. 47, the cartridges may have different vertical dimensions to conform the vertical dimension of a server. In addition, in embodiments cartridges may have different lateral placement of the iris valves and passages to conform to the needs of differing servers and network equipment.
FIG. 49 depicts a server assembly 1000 with a full complement of single rack unit servers 305.
As shown in FIG. 50, the server rack assembly and servers are optionally enclosed in a cabinet that includes side exterior panels 5005 and 5006, top exterior panel 5025 and bottom exterior panel 5008. All of the quarter panels are attached to an intermediate frame to be fully supported. The entire rack is elevated from a support surface by legs 5020 or, alternatively, on casters. The top panel is provided with passages that allow air to flow to the forward panels 1210, 1215 and rearward panels 1211, 1216 that is contained within exterior panels. Additional passages, not pictured, may be added to exterior panels 5008 and 5025 for power, network cables, and other cabling.
Referring now to FIG. 51, an assembled rack system 1000 includes exterior side panels 5005 and 5006 that contain the side forward panels and rearward side panels. In embodiments, there are front and rear doors provided that can be used to close and lock the whole rack. In further embodiments, the panels used are insulated. Again referring to FIG. 51, the top of the device includes front top passages 5121 and 5130 that communicate with the forward lateral side panels. Next to the inlet passages 5121 and 5130 are pressure relief valves 5128 and 5131. When the pressure in the system exceeds a predetermined pressure, the valves will release air to the atmosphere and prevent damage to components of the system. Similar pressure relief valves 5138 and 5142 are located in the rear panel adjacent to rear top passages 5125, 5135. On the top of the panel is a controller 5150 that is in communication with the cartridges via wires 5140.
A top view of a building rack device system 1000 is depicted in FIG. 52 that includes an air conditioner 5204 that provides cool air to top inlet passages in forward panels through conduits 5220, 5223. Air, after it has passed through a server, flows to the rearward panels and may exit through top passages 5125, 5135. Air exiting the panels is then directed through conduits 5228 and 5229 to pump 5330 that maintains negative pressure in the exhaust system and moves the air from the forward panels, through the servers and out to the rearward panels. Air from the pump may be transferred back to the air conditioner through passages (not shown) for recirculation through the system.
As shown in FIG. 53 the bottom surface 5310 of a rack system 1000 receives cool air from air conditioner 5204 from conduits 5325. Air is vented from the system through conduits 5329. A pump 5330 is provided that creates and maintains negative pressure in the exhaust air flow system and may transfer air back through passages (not shown) to the air conditioner.
In embodiments, the system includes a controller and servo motor that can adjust the flow parameters depending on the temperature of the server or group of servers. In further embodiments, the system includes a control board that includes a small circuit board with an Ethernet communications port for communication with the servers, a valve controller, air conditioner, heat pump, and a remote central monitoring and control location.
Referring now to FIG. 54, in a further embodiment 1000 air is directed from a cartridge member 2166 to openings provided in the front panel 5412 of server 305 using flexible tubular conduit members 5122. The depiction includes panels 1210, 1211 that receive the cartridges that are described herein, FIG. 55 depicts a top view of the system described above and includes the flexible conduit tubes 5122 that are depicted extending past the front edge 5417 of the server.
In another embodiment of the invention that is depicted in FIG. 56, air is distributed from cartridge member 2166 through flexible tubular members 5122 to openings on the top of a server 305. In this embodiment, server 305 only extends one half the distance of the server rack. FIG. 57, a top view of the embodiment depicted in FIG. 56, shows conduits that extend from the lateral panel 1210 to the top of server 305. Now referring to FIG. 58, a further aspect of the invention is depicted wherein air is removed or vented from the rear of server 305 using flexible conduit hoses or tubular members to cartridge 2166 in rear panel 1211. As seen in FIG. 59, the air is directed from server 305 to the rear panel section 1211 using tubular members 5122.
FIG. 60 depicts a schematic representation of an alternative air flow arrangement in a further embodiment of the invention 1000. In this embodiment servers 305 are attached to the same vertical location that is in turn attached to the front side panel 1210 and rear side panel 1211. Also shown are servers 305 that are also attached to the front side panel opposite 1210 and rear side panel opposite 1211 using conventional rack mount hardware. Air from cartridges provided in the front panel 1210 and rear panel 1211 flows laterally into the servers 305 and exits the servers through openings such as openings 6025. The openings are on the opposite sides of the servers and passages on cartridges (not shown) provided on lateral panels (not shown) that are opposite panels 1210 and 1211 and which receive from the servers and distribute the air out of the panels.
FIG. 61 is a depiction of prior art blade server system 6100 wherein a plurality of server blades 6121, 6122, 6123, 6124, 6125, 6126, 6127 and 6128 are oriented in a vertical direction and contained in an external housing 6110. External housing 6110 is designed to be received in server rack.
FIG. 62 depicts a further alternative wherein an external housing 6120 encloses a plurality of servers such as 6221 and 6222. Blade server system 6200 includes two rows of vertically oriented servers.
FIG. 63 depicts an embodiment of the invention 1000 adapted to provide cool air to and remove air from vertically oriented blade servers. Here, conduit 5122 is connected to a cartridge according to one of the embodiments of the invention discussed above and direct air to an opening provided on the top surface of server 305. Air is removed from server 305 using hollow tubular conduit 5122 which is directed air to a cartridge provided in rearward lateral panel as described above. FIG. 63 therefore depicts a server device in which each of the servers 305 are provided with air flow to and from the server. These conduits 5122 pass through the external casing 6340 that retains the servers and then direct the air laterally.
FIG. 64 depicts a further embodiment 1000 wherein hollow tubular cooling conduits 5122 provide airflow into servers 305. Air is removed from the servers in a similar manner as described with respect to the embodiment 1000 depicted herein.
FIG. 65 depicts a blade server arrangement 1000 wherein air is distributed to servers through openings on their bottom surfaces through tubular conduits 5122. Air is removed from the servers 305 using tubular conduits 5122 and is directed laterally wherein it can be received by cartridge members as described herein provided on lateral panels.
In a further embodiment 1000 depicted in FIG. 66, a row of blade servers 305 includes multiple rows of servers oriented vertically. Air is provided to servers on a lower row using through tubular conduits such as 5122. These conduits provide air flow from lateral sides of the device 1000 and deliver the air to the bottom surface of severs. Air is removed from the servers using similar conduits and directed laterally.
In further embodiments (not shown), fans are provided in the cartridges to assist with air flow to the servers and to assist with the removal of air from the servers. In yet other embodiments the fans may be provided in connection with the intake openings and exhaust opening in the panels, or along the conduits that provide for air handling to and from the panels.
FIG. 67 is a schematic view of a data center building embodiment 2000 wherein a plurality of racks 1000 are positioned in a building structure 6701 and exterior 6702 to constitute a server facility or data center. The data center includes a central controller 6730 that may be in proximity to the data center or in remote communication. The system optionally includes an air conditioner system that includes conventional exterior components 6710 such as a compressor, condenser element and a fan and interior components 6711 that include fans, evaporator coils, and an expansion device for the coolant used in the system. The system may also include heat pump (HP) technology including interior components 6721 which may include a blower, an expansion device, and an exterior coil and conventional exterior components 6720 including a compressor, check valves, an expansion device, exterior coils and a fan.
In yet further embodiments, a variety of rails members are provided in connection with the rack systems to receive different server models, wherein the rails have different designs with different passages to complement the passages in different servers.
Turning now to FIGS. 68-71, the present invention features an embodiment of the cartridge 3100 that is peripherally mounted to the rack stand 4900. Prior versions of the present invention featured a central void that utilized hollow vertical posts 1825 to fill and accept gas therefrom. The embodiments of FIGS. 68-71 instead allow gas to enter/leave server computers without recourse to a centralized void. As shown in FIG. 68, the vertical post member 1825 includes a hollow area 2170 through which gas may be infused or withdrawn. The post 1825 includes a peripheral attachment point with an opening through which gas may enter/leave. With reference to FIG. 76, the stand of the present embodiment includes a peripheral opening 9002 which may be a simple void (e.g., lack of material) or an aperture constructed to dimensionally correspond an opening on the peripheral cartridge. The preferred peripheral cartridge may be slid into position on the member 1825 by use of a recess 9004 sized to accommodate to the body of the peripheral cartridge. Upon joinder, the cartridge/member system would be preferably exhibit a uniform entity such that the surfaces of the member and cartridge are approximately continuous.
With further reference to FIGS. 74-78, the present invention includes a cartridge 3100 capable of electrical power. The cartridge 3100 may include electrical contacts 1945 adapted to form a circuit with a power supply within, or passed through, the member 1945. The member of the present embodiment permits a user of the server rack 4900 to service computers within the rack with relatively little inconvenience.
The member opening 9002 is oriented away from the area that would be occupied by the computer 305. By oriented away, it is meant that opening faces a direction other than one parallel from the exact direction faced by the surface of the member 1825 immediately adjacent to the computer (or where it would be), i.e. the computer support surface. The preferred orientation of the opening is perpendicular to the computer surface such that the opening is accessible when the computer is attached to, or proximate to, the computer support surface. The cartridge is affixed into position to align the opening 9006 of the cartridge with the opening 9002 of the member. Alternatively, a surface of the cartridge may comprise mostly open space such that the cartridge forms the outer surface of the member upon fixation. The gas passes from the member opening 9002 to the cartridge opening 9006 and exits the cartridge via conduit 5122. The conduit 5122 may be directly affixed to the cartridge 3100 or a separate entity such that the cartridge has a second aperture immediately accessible to a user. The preferred embodiment of the cartridge includes a conduit integrated to the cartridge such that airflow passes from the member to cartridge and then into the conduit for transmission to a computer. The cartridge may include any of the features of cartridges previously discussed, including an impediment, e.g. shutter 284.
Although the present embodiment has been discussed primarily in terms of airflow ingress from a master gas source into the member and then into the computer, as with previous rack systems disclosed herein, the cartridge/rack also serves as the basis for gas egress to a heat reservoir. As shown in FIGS. 71-73, the present invention includes cartridges both to transmit gas and receive gas to/from the computer. The rack system 4900 adapted to the peripheral cartridges may be used with any accessory or feature of previously disclosed rack systems disclosed herein, including perforated railings 307 with railing apertures 315, 322 corresponding to apertures in the computer case and the conduit from the cartridge.
Turning now to FIGS. 79-92, the present invention includes an embedded distribution system 7000 (“EDS”) and process of the present invention. In the EDS, the present invention 7000 relates the objectives and function of other embodiments, with an alteration in the physical location of air distribution. The EDS allows the point of fluid distribution and collection to be located within the confines of the server rack itself. The present invention includes a disguised manifold 7200 that has the rough dimensions of a server blade adapted to fit within the server rack. By rough dimensions, it is meant that the width and length of the disguised manifold are exactly identical, or as close as is necessary for the manifold to fit into the server rack using attachment equipment similar to one or more blades within the rack. The server rack side fits cartridges 7300 that feature cartridge rack apertures 7400.
The EDS disguised manifold 7200 includes the airflow input/output apertures as other fluid direction units of the present invention. The version depicted herein includes one or more master apertures 7202 that lead into the interior of the manifold 7200, which is bifurcated such that fluid from one master aperture 7202 is not directly accessible to fluid from the other master aperture 7202. A simple median wall (not shown) placed at the midpoint of the manifold 7200 is sufficient. Within the discussed manifold is an interior manifold void bifurcated to receive fluid from said building inlet conduit via the inlet master aperture and exhaust fluid via the exhaust master aperture to said building outlet conduit. Incoming (cooled) air exits the disguised manifold on its way to a computer, sealed or unsealed, via manifold minor aperture 7206, which may be sized appropriate to regulate pressure within the system. The manifold minor apertures 7206 are present for the purposes of shunting fluid to/from the disguised manifold.
The preferred conduit of the EDS embodiment takes the form of hollow conduit posts 7825. Here, there is a blending of some structure of the present invention, however it should be noted that the hollow conduit posts are not load-bearing structures—although it certain instances they may be used as such or for other maintenance of server blade orientation. Vertical member 7630 and horizontal member 7636 serve as load bearing rack structures. The posts 7825 serve as the piping for transmission of fluid between server blades and from blade to manifold. In concert with the conduit posts 7825, the disguised manifold 7200 may be positioned at the top and bottom (and because it is sized similar to computer blades) and points therebetween. FIG. 85, for example, depicts the preferred arrangement of manifolds. Fluid urging apparatus such as fans or impellers may be positioned in one or more of the manifolds.
Cartridges 7300 may line the exterior of the rack for the interior disposition of computers and disguised manifolds. The cartridges 7300 preferably include rack/post adapters 7320 that project the physical dimensions of the present invention away from the rack structure. Accordingly the conduit posts 7825 may include apertures 7833 specially dimensioned to allow a close size or interference fit. The preferred adapters 7320 include an elastic material that deforms upon contact with an aperture to result in a tightly sealed fit between the conduit post 7825 and the cartridge 7300. Alternatively, the adapters 7320 may be positioned on the conduit posts 7825 facing inwardly for the projection of the physical dimensions of the post 7825 into the aperture 7400 of the cartridge 7300.
The conduit posts 7825 of the present invention include hollow, generally self-supporting transmission structure that can be positioned upon the sides of the rack for the transmission of air to/from computer-to-computer or computer-to-manifold (and vice versa). The preferred post is constructed of an insulated plastic and has a height approximately equivalent to the height of the rack, or at least the height of a full complement of computers within the rack. The post 7825 includes a post contact portion 7827 and a post bay 7829. The contact portion 7827 is dimensioned to form a close-fit relationship with the cartridges 7300 of the present invention, which serve to provide a uniform surface that mates with the contact portion 7827 of the conduit post 7825. Naturally, to serve as effective conduit, the conduit posts 7825 require a sealed environment and an interior that permits fluid flow. Fluid is injected into the conduit post 7825 and may traverse the interior of the conduit post until the furthest depths of the post bay 7829. The bay 7829 is the interior space of the post that allows fluid to traverse throughout the post. In the present invention, the post bay forms a single, continuous void that lacks internal wall structuring for specific routing of fluid. Fluid can be specifically routed into desired computer blades using cartridges that allow selective entry into computers. The apertures 7833 of the conduit posts 7825 preferably run the height of the post 7825 such that there is a post aperture 7833 corresponding to each cartridge adapter 7320 (if present) or cartridge aperture 7400 (if an adapter is not present). In instances where fluid flow is not desired from a computer to the conduit post, a stopper (not pictured) may be utilized that simply serves as a physical barrier and is dimensioned to elastically fit the post aperture 7833.
A post cover 7831 can be removable and positioned co-extensive with the contact surface 7827. In other embodiments the post cover 7831 is unitary with the conduit post, and still others the post cover 7831 is aggregated from individual cartridges that are sized to accept merely a single adapter 7320. Accordingly ‘blank’ post cover cartridges can be provided analogous to stand cartridges 7300 that allows the post cover 7831 to be constructed of constituent elements. The post apertures 7833 will vary in size, placement, and number with the adapters 7320 on the stand. The spacing of the post apertures can vary based on the dimensions of the post cover cartridges or spacing between adapters 7320. The advantage in a removable post cover 7831 or other removable portion of the conduit post is that it allows access to the interior of the post for cleaning and maintenance. The conduit posts in preferred embodiments exclusively handle incoming fluid and outgoing fluid respectively. Furthermore, the conduit post preferably permits the unhindered fluid flow throughout the entirety of the body thereof; and by permitting all of one type of fluid (i.e., heated computer exhaust fluid or cooled input fluid), the need for internal conduit channeling is obviated and where multiple flexible conduit segments were used, now merely a single substantially rigid conduit post may be used.
An advantage of the present invention resides in the overall aggregation of components of the server rack system 7000. Support rails 7630 and cross rails 7636 as in conventional rack systems support the weight of server blades placed within the system. One of the often unconsidered byproducts of a conventional rack and the present invention 7000 is that the members 7630 contract when exposed to the often considerable weight of a fully, or even partially, loaded rack causing the entire rack to sag by multiple millimeters. Accordingly conduit or other connections between components placed on the apex of a rack and within the rack, in order to maintain a static connection, require elasticity or slack to accommodate the displacement. In prior descriptions of the present invention, one of the preferred versions of shunting fluid into the rack and server blades includes the use of cartridges and hollow components with flexible conduit, see e.g., FIGS. 53, 54, 78A. The preferred embodiment of the present invention as depicted in FIGS. 79-90 positions the manifold 7200, or that it is to say, the part and means of the invention that distributes fluid to rack servers within the sections of the rack that participate in “rack displacement” perhaps even to the same degree, or proportionally to a similar degree, as the server blades themselves. Note that the manifold 7200 is positioned both in concert with the conduit 7002 and the blades 7305. All three of these components 7002, 7200, 7305 displace together.
In constructing the present invention, sagging is not necessarily a desired trait. It is often considered in the art that racks ought not be fully loaded, and some believe that less than a half rack complement should be considered a limit. Further reasons to avoid a ‘full complement’ of server racks includes the fact that the close-fit placement of adjacent server racks creates thermal management concerns so that adjacent server blades contribute to the thermal load of nearby other blades. One often sees blades placed within the rack in an alternating arrangement so as to ameliorate thermal problems associated with closely-spaced heated elements. However, as mentioned, sagging is more of an inevitable result than a sought result, and the present invention is constructed to minimize the effects of sagging. The support members 7630, 7636 should be constructed of high strength materials such as steel or aluminum. These components should be displaced as little as possible. However, because displacement is inevitable, the conduit 7825 should be constructed of a non-metallic material, and presently the conduit is constructed of a plastic composite. The cartridges, when used, flex with the blades as the blades are urged downward with the weight of the blades. Any manifolds, when in many versions of the present invention may be, placed upon the top and or lower extent of the rack blade stack “floats” in a position that ‘rides’ with the blades. Accordingly the materials of the manifolds may be constructed of either a metal or non-metal.
Turning now to FIGS. 93-95, the present invention may feature Temperature-Pressure (“TP”) monitoring and adjustment. Practical experimentation has shown that the TP within the server computers 305a, 305b will vary with use and server quantity, and the possibility of air gaps 305c for unused server space. Each added server 305 will alter the pressure of gas flowing within the system, and one of the more rudimentary fixes to regulate TP is to control the passage of gas through the apertures of the system. The EDS 7202 can be a first source of TP control through aperture alteration. Gates 2804 can be positioned within any of the apertures of the present invention to regulate the passage of gas. Physical monitors 7611, which can detect and transmit any physical measurement back to the system (including temperature and pressure), can provide instantaneous feedback concerning TP. Gates 2804 can be actuated to occupy any extent of the cross section of the aperture, whether in aperture 7202 (i.e., in and out of the EDS to the building conduit) or 7206 (i.e., in and out of the tributary posts). In some instances, as shown in FIG. 94, apertures 7206 can be wholly obstructed to stop the ingress/egress of gas. In other preferred embodiments, the apertures 7202 can be permanently obstructed or even omitted.
Accordingly, pursuant to a TP monitoring process 7700 of the present invention, the system can urge 7702 gas through the rack system. A physical attribute can be measured 7704, including temperature and pressure. Based on the measurement of TP, one or more of the server apertures, here to include any aperture that leads from one component to another, for example, EDS-to-post, post-to-EDS, post-to-server, server-to-post, etc., can be obstructed 7706 partially or wholly. The obstruction can occur prior to, or subsequent to, an initial fabrication of any system component. The measurement 7704 and obstruction 7706 steps can occur repeatedly until the desired TP is reached.
The conclusions drawn from this practical experimentation has shown that in the use of multiple EDS components, it may be preferred to permit one of the EDSs to be a “pass-through” entity. In other words, the EDS itself acts as a pressure-regulator that ensures that the appropriate pressure is found in the server computers therebetween or otherwise. This has mostly been shown to be beneficial in the optimal scenario wherein the EDSs engulf the server computers. The results indicate the selected, adjustable, moment-to-moment, or even permanent obstruction, of component-to-component apertures can be very advantageous to ensuring the appropriate pressure of gas to maintain appropriate temperatures within the system. Monitors 7611 can be positioned in any area of the system wherein it may be desired to understand the physical attributes of the system. As shown, the monitors are in two positions, immediately following the post-computer aperture, and immediately adjacent to the computer-post aperture. In this orientation the monitors can ascertain the TP within the computer and the effect of the gas pressure on the temperature upon entering and leaving the computer. Monitors can be placed in one or more of the computers, or in the posts or EDS systems such that temperature and pressure can be determined in an initial state and final state. For example, an unduly high temperature in the initial state may indicate an equipment failure for an air motivator while an unduly high temperature proximate to the exhaust of the EDS may indicate a lack of adequate pressure within the system based on leakage, inadequate powering, or other issue.
As shown in FIGS. 96-98, the rack system can be fabricated to lack the master apertures 7202. It has always been the case that the number of master apertures could be present in any quantity in any position suitable to perform their function, but what was unclear was the relationship between the master apertures and the internal pressure of the rack system. For the present invention, it can be advantageous for a single master aperture 7202 to serve as an inlet master aperture and a single master aperture 7202 to serve as an exhaust. Preferably, when in such an arrangement the inlet and exhaust are situated on opposite ends of the rack system, and more preferably, the computers are sandwiched therebetween. The conduit posts 7825 can be accessed as desired by the present invention such that merely a single post per side may be utilized, dual posts, or obstructed single or dual posts. Furthermore, the role of the master apertures can be reversed or altered as the circumstances may warrant. The depicted rack systems show that there is but a single master aperture per manifold EDS 7200. This embodiment may be justified when a facility shop decides that the air motivation intensity combined with the quantity and type of server computers along with their arrangement in the rack system can support a permanent aperture solution. This permanent solution may be mathematically/theoretically derived or result from the process of FIG. 95. In this sense the second, lower manifold has been termed a “linking” manifold because it emulates the ‘flowthrough’ that would be experienced in a computer. The upper manifold includes bifurcation that shunts air in multiple directions. Generally speaking, the lower manifold would be doing this as well. However, in certain versions, the linking manifold serves the purpose of allowing air to pass from conduit to conduit without (i) contacting any internal computer components, and (ii) without the loss of pressure through the accessing of master apertures. So, when one or less master apertures are present on a manifold, it would be considered a linking manifold. FIGS. 96-98 demonstrate flow pathways of the present invention along with a baseline configuration.
Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions would be readily apparent to those of ordinary skill in the art. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein.
