BACKGROUND
Field
The present invention relates generally to structures for housing data processing equipment, and, in particular, to data processing equipment structures that provide enhanced airflow solutions.
Background
Racks, frames and enclosures for mounting and storing computer and other electronic components or equipment have been well known for many years. Racks and frames are typically simple rectangular frameworks on which electronic components may be mounted, or on which other mounting members, such as shelves or brackets, may be mounted which in turn may support the electronic components. Enclosures are typically frames on which panels or doors, or both, are hung to provide aesthetic improvement, to protect the components from external influences, to provide security for the components stored inside, or for other reasons.
Racks, frames and enclosures have been built in many different sizes and with many different proportions in order to best accommodate the components which they are designed to support and store. Components stored in these enclosures may include audio and video equipment and the like, but quite frequently include computer equipment and related peripheral devices. These components typically include housings enclosing internal operative elements.
As is also well known, the electronic equipment mounted in these structures tends to generate large amounts of thermal energy that needs to be exhausted away from the equipment effectively in order to maintain the equipment in proper operating order or to prevent damage thereto. The problem can be especially significant when the components are enclosed in enclosures, because thermal energy generated thereby can concentrate within the equipment enclosure and cause the components to overheat and shut down. As equipment becomes more densely packed with electronics, the quantities of thermal energy have continued to increase in recent years, and thermal energy management has become a significant issue confronting today's rack, enclosure, frame and enclosure manufacturers, the manufacturers of the electronic equipment, and the users of such equipment.
Typically, multiple racks, frames, enclosures, and the like (sometimes collectively referred to hereinafter as “enclosures”) are housed together in a data center room. Because of the overheating problem, and particularly with multiple enclosures being placed in a single room, thermal management of the data center room is very important. A goal of data center thermal management is to maximize the performance, uptime and life expectancy of the active components being housed in the room. Toward this end, data center rooms are often arranged so as to increase efficiency and optimize performance.
One common way of organizing a data center room to meet these objectives involves arranging individual enclosures in rows, with the air intake of each enclosure facing toward one side of the row and the heated air exhaust of each enclosure facing toward the other side of the row. Rows of enclosures are arranged in back-to-back relationship so that enclosures of two separate rows exhaust heated air into a common “hot” aisle between the rows. Heated exhaust air from the hot aisle is then drawn into a cooling unit—often arranged as an in-line unit within the row of enclosures. The cooled air is then deposited back into the ambient space of the data center room to be re-used in the cooling process.
In such an arrangement, however, several drawbacks are known to exist. For instance, the establishment of a hot aisle between rows eliminates the possibility of having dedicated cooling units to manage the cooling process for each row individually. Additionally, under existing hot aisle methodology, the entire space of the data center room must be kept cool in order to provide a ready supply of cooled air available to the enclosure intakes. Due to its typically large volume, the data center room is generally incapable of being adequately pressurized.
Accordingly, a need exists for improvement in the arrangement of equipment enclosures within a data center room so as to further enhance efficiency and performance. This, and other needs, is addressed by one or more aspects of the present invention.

DETAILED DESCRIPTION
As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.
Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.
Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.
Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.
Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”
When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers,” “a picnic basket having crackers without cheese,” and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”
Referring now to the drawings, in which like numerals represent like components throughout the several views, the preferred embodiments of the present invention are next described. The following description of one or more preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
FIG. 1 is a front orthogonal view of a data processing equipment structure 10, in accordance with one or more aspects of the present invention, shown with cooling units 14 disposed at ends of a row of equipment enclosures 12. FIG. 2 is a front orthogonal view of a data processing equipment structure 10, in accordance with one or more aspects of the present invention, shown with cooling units 14 disposed at an end and intermediate of ends of a row of equipment enclosures 12. As used herein, the term “data processing equipment” refers to a wide range of electronic equipment as well as racks, frames, enclosures, and the like that are typically used to house such equipment.
As shown in FIGS. 1 and 2, the data processing equipment structure 10 generally includes sidewalls 22,24 and a ceiling panel 28. Together, the sidewalls 22,24 and ceiling panel 28 enclose a row of enclosures 12 resting on a floor surface 40 in a data center room. In a preferred embodiment, the sidewalls 22,24 and ceiling panel 28 are solid so as to prevent mixing of air from outside the structure 10 with the controlled environment within. Although not a required feature, the structure 10 may optionally include a floor panel 26 resting on or above the floor surface 40 such that the row of enclosures 12 rests on the floor panel 26. In FIGS. 1 and 2, the front sidewall 24 and ceiling panel 28 are shown as being transparent in order to illustrate the row of enclosures 12 contained within the structure 10, while the other walls are shown as being opaque. In fact, any of the panels may be transparent or opaque as desired.
As further shown in FIGS. 1 and 2, one or more in-line cooling units 14 are arranged within the row of enclosures 12. In FIG. 1, a cooling unit 14 is disposed at each of the two ends of the row of enclosures 12. However, there may also be a need to include a cooling unit 14 intermediate of the ends of a row of enclosures 12, as shown in FIG. 2. While two cooling units 14 are depicted in each of FIGS. 1 and 2, more or less cooling units 14 may be included, as might be appreciated by the Ordinary Artisan. Cooling units 14 are generally, though perhaps not always, disposed proximate to enclosures 12 that house equipment in need of cooling. Because all enclosures 12 may not be in use at all times, the location of the cooling units 14 within the row can be matched with enclosures 12 that are in use. Enclosures 12 house a wide variety of electronic equipment, including storage equipment, servers, switches and other like devices and equipment for data processing. Cooling units 14 embedded within the row may utilize a wide variety of cooling solutions, including DX cooling, chilled water cooling and other types of economized cooling solutions.
FIGS. 3 and 4 are respective front and rear orthogonal views of the data processing equipment structure 10 of FIG. 2, shown with circulation lines or arrows illustrating airflow. The front sidewall 24 and ceiling panel 28 in FIG. 3 and the rear sidewall 24 and ceiling panel 28 in FIG. 4 are shown as being transparent in order to illustrate the row of enclosures 12 contained within the structure 10. FIG. 5 is a sectional view of the data processing equipment structure of FIG. 2, taken along line 5-5. As collectively shown therein, the structure 10 is divided or compartmentalized to define a front plenum 50 at or along the front side of the row of enclosures 12 and a rear plenum 60 at or along a rear side of the row of enclosures 12. In the arrangement shown, the front plenum 50 houses the cool air supply of the structure 10 provided by the cooling units 14 and is in fluid connection with the air intakes of the various enclosures 12, while the rear plenum 60 contains heated exhaust air exhausted from equipment mounted within the enclosures 12 and is in fluid connection with the air intakes of the cooling units 14. However, it will be appreciated that this arrangement may be reversed such that the rear plenum 60 houses the cool air supply and the front plenum 50 contains the heated exhaust air.
The front plenum 50 and rear plenum 60 are separated from one another by the enclosures 12 and the cooling units 14 in combination with one or more separation panels 16,18. As perhaps best shown in FIG. 5, separation panels 16 extend from the tops of the air cooling units 14 to the ceiling panel 28, and separation panels 18 extend from the tops of the enclosures 12 to the ceiling panel 28. Separation panels 16,18 thus ensure that the cool air supply of the front plenum 50 is isolated from the heated exhaust air of the rear plenum 60.
As shown in FIG. 3, cool air (represented by arrows shown in outline form) enters the front plenum 50 via the cooling units 14 and is dispersed within the front plenum 50. Separation panels 16,18 prevent the cool air in the front plenum 50 from mixing with the heated exhaust air in the rear plenum 60. Cool air is then drawn into the air intakes of the enclosures 12 to cool equipment mounted therein. Conveniently, the cooling units 14 may be arranged within the row at locations proximate to enclosures 12 that house equipment to be cooled.
As shown in FIG. 4, heated exhaust air (represented by arrows shown in solid form) is exhausted from the rear sides of the enclosures 12 into the rear plenum 60. Heated exhaust air is contained within the rear plenum 60, separate from both the front plenum 50 and any other rows of electronic equipment within the data center room. From the rear plenum 60, heated exhaust air is drawn into the air intakes of the cooling units 14 where it is cooled before being reintroduced into the front plenum 50 as cooled air.
FIG. 6 is a front orthogonal view of a data processing equipment structure 10, in accordance with one or more aspects of the present invention, shown with an internal sidewall 30 to scale the size of the internal space for housing equipment enclosures 12. In FIG. 6, the front sidewall 24 and ceiling panel 28 are once again shown as being transparent in order to illustrate the row of enclosures 12 contained within the structure 10. As shown in FIG. 6, the structure 10 is capable of easy modification in order to suit the particular needs of a data center. More particularly, if only a few enclosures 12 are required for a particular data center, an internal sidewall 30 may be configured within the structure 10 to isolate any unneeded space (i.e., the space at the rightmost end of the structure 10 of FIG. 6) from actively used space (i.e., the space at the leftmost end of the structure 10 of FIG. 6) where electronic equipment is maintained. The internal sidewall 30 may be located in any of a number of different positions within the structure 10 so as to permit scaling the size of the structure 10 to a preferred size to accommodate more or less equipment enclosures 12. As such, the internal space of the structure 10 is capable of expansion or reduction in size to address particular needs of a data center.
In accordance with another aspect of the present invention, the structure 10 may be configured to provide additional scalability features. In particular, individual enclosures 12 within the row may be fitted with active and passive louvers (not shown) such that each individual enclosure 12 may be rendered active or inactive within the structure 10. Furthermore, it is also contemplated that individual enclosures 12 within the row may include solid caps (not shown) capable of being fitted to the front or rear of the respective enclosure 12, thereby covering the air intake or hot air exhaust of the respective enclosure 12. In this regard, individual enclosures 12 may be rendered inactive without the need of removing the enclosure from the structure 10.
As shown in FIGS. 1-6, the structure 10 provides an environment for thermal management of a row of equipment enclosures 12. Where the data center room includes multiple rows of equipment enclosures, thermal management of each individual row is possible in accordance with the present invention, as the supply of cool air in the front plenum 50 and heated exhaust air in the rear plenum 60 of a particular row can be effectively isolated from other rows. Each individual row of equipment enclosures 12 is capable of thermal management by one or more dedicated cooling units 14 within the row. As such, what is often a very complex air space within a data center room can be simplified in a manner such that each row is capable of being managed independently of other rows.
By limiting the air interaction between separate rows of electronic equipment 12, the methodology of the present invention simplifies control of the thermal management process. Cooling needs for each individual row can be ascertained, which facilitates the application of simple control algorithms to manage the process and maximize airflow and cooling efficiency of each row in the data center room. With enhanced airflow efficiency, cooling units can operate at a lower power state, thus enhancing power consumption of the structure 10 as well.
Separation of the front plenum 50 from the rear plenum 60 further enhances the energy efficiency of the structure 10 by reducing or minimizing wasted airflow arising from recirculation or bypass, which can ultimately increase the rate of heated air exhausted into the rear plenum 60 during the cooling process. Such an increase facilitates an improvement in the efficiency of cooling coils of the cooling units 14, which allows for a reduction in cooling unit fan speed. In this regard, a reduction in fan speed can reduce power consumption and thereby enhance the energy efficiency of the structure 10.
Energy efficiency of the structure 10 is also enhanced by the relatively short airflow path afforded by the structure 10. Cooling units 14 can be located within the row to be proximate to enclosures 12 that house electronic equipment. By coupling cooling units 14 with enclosures 12, the airflow path can be direct and short, thus providing a ready supply of cool air in the vicinity of the enclosure 12. Furthermore, as shown in FIGS. 1-6, the volume of the front plenum 50 is relatively small, which can facilitate a pressurized state. Such pressurization at the cool air intake of enclosures 12 can further enhance airflow through electronic equipment.
In accordance with various aspects of the present invention, power may be provided to the cooling units 14 and electronic equipment mounted within the enclosures 12 by means of a busway. Power may also be provided to the cooling units 14 and electronic equipment mounted within the enclosures 12 via conduit and junction boxes. In accordance with other aspects of the present invention, the structure 10 may be fitted with various integrated systems, such as security systems, fire suppression systems, lighting systems and general IT management operation systems. In this regard, the structure 10 of the present invention is capable of managing a multitude of functions for an individual row of enclosures 12, including thermal management, power, fire suppression and other critical functions.
It is further contemplated that multiple structures 10 can be organized within a single data center room, with each separate structure 10 being specifically configured to enhance or optimize thermal management with respect to equipment mounted therein.
FIG. 7 is an isometric view of a second embodiment of a data processing equipment structure 110 in accordance with one or more aspects of the present invention. As shown therein, the data processing equipment structure 110 generally includes a plurality of equipment enclosures 112 organized in a row and at least one cooling unit 114. Although one cooling unit 114 is shown, it is contemplated that multiple cooling units 114 may be implemented within the row. The cooling unit 114 includes or operates in conjunction with a cooling fan 117 to assist in facilitating airflow during the cooling process. The structure 110 further includes an overhead duct 115 (shown as being transparent in FIG. 7) for containing and directing air during the cooling process. The overhead duct 115 is in fluid communication with the enclosures 112 and the cooling unit 114.
In accordance with this embodiment, airflow can be directed such that cool air is drawn into the enclosures 112 from the environment in which the structure 110 is organized. Cool air is utilized to cool equipment mounted in the enclosures 112 and is then exhausted into the overhead duct 115 as heated exhaust air. From the overhead duct 115, heated exhaust air may be directed toward the in-line cooling unit 114 where the heated exhaust air is cooled before being reintroduced to the supply of cool air outside of the structure 110.
Airflow can also be directed such that cool air is drawn into enclosures 112 from the overhead duct 115. In this arrangement, cool air is utilized to cool equipment mounted in the enclosures 112 and is then exhausted into the environment outside the structure 110 as heated exhaust air. The in-line cooling unit 114 then draws heated exhaust air from the exterior environment to be cooled before being reintroduced to the supply of cool air contained within the overhead duct 115.
FIG. 8 is an isometric view of a third embodiment of a data processing equipment structure 210 in accordance with one or more aspects of the present invention. As shown therein, the data processing equipment structure 210 generally includes a pair of rows of equipment enclosures 212 that are arranged in side-to-side relationship. Together, the rows of enclosures 212 define an aisle 219 therebetween. The structure further includes a cooling unit/fan 217 above the aisle and an overhead duct 215 (shown as being transparent in FIG. 8) for containing and directing air during the cooling process. The overhead duct 215 is in fluid communication with the enclosures 212 and the cooling unit/fan 217. Although one cooling unit/fan 217 is shown, it is contemplated that multiple such units may be implemented above the aisle 219. It is further contemplated that one or more doors may be utilized to seal ends of the aisle 219 from the outside environment and provide access to the aisle 219 when necessary.
In accordance with this embodiment, airflow can be directed such that cool air is drawn into enclosures 212 from the aisle 219 between the rows. In this regard, enclosures 212 of each row may be arranged such that cool air intakes face toward the aisle 219, and the aisle 219 between the rows operates as a “cold” aisle for containing a supply of cool air. Cool air is utilized to cool equipment mounted in the enclosures 212 and is then exhausted into the overhead duct 215 as heated exhaust air. The cooling unit/fan 217 above the aisle 219 then draws heated exhaust air from the overhead duct 215 into the cooling unit/fan 217, where the heated exhaust air is cooled before being reintroduced to the supply of cool air contained within the aisle 219.
Airflow can also be directed such that cool air is drawn into the enclosures 212 from the overhead duct 215. In this arrangement, cool air is utilized to cool equipment mounted in the enclosures 212 and is then exhausted into the aisle between the rows of enclosures 212 as heated exhaust air. In this regard, enclosures 212 of each row may be arranged such that heated air is exhausted toward the aisle 219, and the aisle 219 between the rows operates as a “hot” aisle for containing heated air exhausted from the enclosures 212. From the aisle 219 between the rows, heated exhaust air may be directed toward the cooling unit/fan 217 above the aisle 219 where the heated exhaust air is cooled before being reintroduced to the supply of cool air contained within the overhead duct 215.
FIG. 9 is an isometric view of a fourth embodiment of a data processing equipment structure 310 in accordance with one or more aspects of the present invention. As shown therein, the data processing equipment structure 310 generally includes a plurality of equipment enclosures 312 organized in a row and at least one in-line cooling unit 314. Although just one cooling unit 314 is shown, it is contemplated that multiple cooling units 314 may be implemented within the row. The cooling unit 314 includes or operates in conjunction with a cooling fan 317 to assist in facilitating airflow during the cooling process. The structure 310 further includes an overhead duct 315 and a separate side duct 319 arranged at a side of the row, each being in fluid communication with the enclosures 312 and the cooling unit 314.
