Description

  The present invention relates to a container type data center.

  Rather than creating equipment and facilities from the ground up, install equipment such as computers and storage batteries inside transport containers, install them on trucks, move general roads, and create them quickly in the field. To be done. In this way, the target device or equipment can be created in a short time on site.

  By using such a container, it is possible to move equipment via a general road, and it is possible to separate the manufacturing place and the installation place. In particular, if it is possible to move to another place after once installed in a certain place, it becomes easy to flexibly change the equipment configuration and the installation place.

  Such minimum basic functions (for example, in the following data centers, servers, racks, security devices, lighting, fire extinguishing equipment, communication lines, power supply, etc.) The idea of installing devices and equipment by preparing a system equipped with a device in a container and using them collectively is used in various technical fields.

  In a container-type data center that houses multiple server racks, it is possible to construct a data center at low cost by using ISO standard containers for transportation. In order to be able to carry trucks, the ISO standard specifies a width of about 2438 mm (inside dimension: 2352 mm), but considering the heat insulating material and walls for maintaining the environment inside the container, the inside dimension is about 2080 mm. End up. Therefore, even if the server rack is slid, it is difficult to secure a stroke length sufficient to obtain a space necessary for maintenance (see FIG. 20).

  Here, since the server rack takes in cool air from the front and discharges hot air to the back, generally the front of the server rack is a cool air space and the back is the hot air space. For this reason, since the air conditioner is attached to a wall surface or a ceiling surface in the longitudinal direction of the container, it is preferable that the server rack is arranged with the front surface of the server rack facing the container side surface.

U.S. Pat. No. 7,278,273

  However, the 19-inch server rack defined by the EIA standard is generally 700 mm wide and 1100 mm deep. When the server racks are lined up on the side of the container and facing the front of the server rack, the server rack door opens and closes. In some cases, it was not possible, or space required for maintenance could not be secured.

  In this regard, for example, in Patent Document 1, such a problem is solved by arranging the front surface of the server rack to be inclined with respect to the side surface of the container. However, when the server racks are arranged obliquely in close contact with each other, it is necessary to move the server racks in the depth direction during maintenance, and it is difficult to secure a lateral maintenance space.

  As one means that can avoid such a problem, it is conceivable to place a close server rack by turning it at a high angle (an angle exceeding 45 degrees and up to about 75 degrees). However, the space utilization efficiency in the longitudinal direction of the container deteriorates.

  In order to turn the server rack, it is common to install a caster on the server rack. However, in reality, the center axis when turning is not fixed, and it is damaged by contact with surrounding objects such as air conditioners and lighting. There is a risk of it. For this reason, a space larger than the necessary space for calculation is required.

  Further, if the server rack is moved by a caster attached to the server rack, the server rack is displaced, which is inconvenient to handle and difficult to return to the original position after maintenance.

  The present invention provides a container-type data center that can improve the efficiency of use of space in a container, secure sufficient space for maintenance, and easily return a server rack after maintenance to its original position. The purpose is to provide.

In order to solve the above problems, the present invention provides a container-type data center constituted by a container having a server rack in which electronic devices are installed.
A rotation mechanism is provided that enables the server rack to rotate about a vertical rotation axis.

  In the container type data center configured as described above, the server rack can be rotated around the vertical axis by the rotation mechanism. In such a case, the server rack can be rotated around the vertical axis without placing the server rack in a close state and obliquely, so that a space for maintenance can be secured, and the server rack can be centered on the predetermined vertical axis. According to the mechanism for rotating the server rack, the server rack after the maintenance can be easily returned to the original position, and the handling is easy. Furthermore, according to the mechanism that rotates the server rack around a predetermined vertical axis within a fixed area, there is no risk of damage due to contact with surrounding objects, and more space than necessary for calculation is required. It will never be. Therefore, the space efficiency is improved and the storage efficiency of the server rack in the container is also improved.

  The container-type data center may be one in which a server rack connection body formed by connecting N server racks (N is two or more) is integrally rotated by the rotation mechanism.

  In this case, a maintenance space necessary for maintenance of the electronic device may be secured between the adjacent server rack coupling bodies.

  In this case, the maintenance space may be secured when the server rack coupling body is rotated to a predetermined direction.

  In this case, a rotating shaft that constitutes the rotating mechanism may be attached to a rack connecting bracket that connects the server racks.

  The rotation mechanism may further include a slide mechanism that moves the server rack in a horizontal direction.

  The rotating mechanism may include a rotating bed that rotates the server rack at a lower portion of the server rack.

  The rotation mechanism may include a rotation shaft arranged on the ceiling of the container.

  A shielding plate that shields a part of the air flowing through the container may be attached to the server rack.

  Further, in a container-type data center, an indoor unit constituting an air conditioner is installed in the container, and the server rack is disposed at a position that does not interfere with the indoor unit when rotated by the rotating mechanism. Good.

  Further, in the container type data center, the indoor unit constituting the air conditioner is installed along the longitudinal direction in the container, and the rotation axis of the rotation mechanism is opposite to the indoor unit with respect to the center in the width direction of the container. The server rack may be eccentric to the side, and the front side of the server rack may be disposed on the side where the indoor unit is present.

  The container-type data center further includes a cable rack disposed at an upper portion in the container, and a cable hung on the cable rack and connected to the electronic device, and the cable extends along the rotation axis. May be wired.

  According to the present invention, it is possible to improve the utilization efficiency of the space in the container, to secure a sufficient space for maintenance, and to easily return the server rack after the maintenance to the original position.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  A container-type data center 1 according to the present invention is constituted by a container 2 including a server rack in which an electronic device 50 is installed, and includes a rotation mechanism 6. FIG. 1 is a plan view showing an example of the overall layout of the container-type data center 1, and FIG. 2 is a side view.

  The container 2 is a rectangular box-shaped housing made of, for example, steel, aluminum, fiber reinforced plastic (FRP), or the like. A container lifting hook, holes and protrusions for fixing the container feet, and walls having a structure that allows air to pass therethrough may be provided. The length, width, and height of the container 2 are not limited as long as land transportation and sea transportation are possible. In addition, a standard container defined by ISO may be used.

  In addition, the walls of the container 2 in the shape of a rectangular box (the front wall with the entrance / exit 42, the back wall on the opposite side, and the side walls on both sides), the floor, and the ceiling (six sides) are made of heat insulating materials and plates or concrete plates. It may be surrounded by. It is preferable that these six surfaces have a structure that allows easy on-site processing of through-holes for installation of an air conditioner and ventilation.

  The interior of the container 2 is divided into a front room 70 and a server room 80 by a partition (partition wall) 40 with an internal door (entrance door) 41. Although not shown in particular, the front chamber 70 is provided with doorways and doors for workers. Workers can enter the server room 80 through the doorway provided with the door and the doorway 42 provided with the internal door 41. In FIG. 1, reference numeral 12 denotes an outdoor unit, and reference numeral 14 denotes a distribution board.

  A server rack 3 is arranged in the server room 80. Although not particularly illustrated, the server rack 3 is provided with devices such as computers and storage batteries (collectively referred to as electronic devices in the present specification and indicated by reference numeral 50).

  In the present embodiment, two server racks 3 are connected to form a set of server rack connections 4 (see FIG. 1 and the like). The server rack connector 4 is normally arranged along the longitudinal direction x of the container 2 such that the front and back surfaces of the electronic device 50 and the server rack 3 face both side walls of the container 2 (see FIG. 1). In FIG. 1, the width of the server rack 3 alone is represented by a symbol w, the depth is represented by a symbol d, and the diagonal length of the server rack coupling body 4 (however, the diagonal length in the plan view) is represented by a symbol t. Represents. Moreover, the space | interval (space between connection bodies) of the adjacent server rack connection body 4 in normal arrangement | positioning is represented by the code | symbol s.

<Rotation mechanism>
The rotation mechanism 6 is a mechanism for enabling the server rack 3 to rotate around a rotation shaft 61 extending in the vertical direction. An example of a specific configuration of such a rotation mechanism 6 is shown below (see FIGS. 3 to 5). However, these are only suitable examples, and the configuration is not limited to these examples.

  The rotation mechanism 6 can be composed of, for example, a rotation shaft 61, casters 63, a mounting plate 64, and a floor mounting plate 65 (see FIG. 3A). The caster 63 is composed of a plurality of wheels for movement or rotation arranged on the bottom surface of the server rack 3 (or the server rack coupling body 4). The mounting plate 64 is mounted near the rotation center of the server rack coupling body 4 (between a set of server racks 3 as an example). The floor mounting plate 65 is mounted near the rotation center on the floor surface of the container 2. Between the mounting plate 64 and the floor mounting plate 65, a rotating shaft 61 is rotatably mounted on at least one of the mounting plate 64 and the floor mounting plate 65. With such a rotation mechanism 6, the server rack 3 (or the server rack coupling body 4) can rotate around the rotation shaft 61.

  Of the rotating mechanism 6, a portion excluding the casters 63 may be installed on the ceiling side instead of the floor side. That is, a ceiling mounting plate 66 can be adopted instead of the floor mounting plate 65, and these can be installed between the server rack 3 (or the server rack connector 4) and the ceiling of the container 2 (see FIG. 3B). ). Alternatively, both the floor-side rotation mechanism 6 and the ceiling-side rotation mechanism 6 described above may be installed (see FIG. 3C).

  The mounting plate 64 in the example shown in FIG. 3 is mounted on the server rack 3 (or the server rack coupling body 4) in a vertically leaning state. Instead, the mounting plate 64 is in a state of being laid down horizontally. May be attached to the server rack 3 (or the server rack connector 4) (see FIGS. 4A to 4C).

  Or you may form the rotating shaft 61 which comprises the rotating mechanism 6 by the one axis | shaft which continues from the ceiling of the container 2 to the floor (refer FIG. 5 (A)). Alternatively, a part of the rotating shaft 61 that continues from the ceiling to the floor is formed in a plate shape, and the plate-like portion is positioned between the server rack 3 and the server rack 3 to connect the server rack 3 to a rack connecting bracket. 67 (see FIG. 5B). In other words, in this case, the rotating shaft 61 is attached to the rack connecting bracket 67 that connects the server racks 3. According to the rotating mechanism 6 having such a function of the rack connecting bracket 67, the interval between the server rack 3 and the server rack 3 is further narrowed by fixing the upper and lower portions of the server rack 3 to one set. The rotation diameter of the server rack 3 can be reduced.

  Alternatively, the rotating mechanism 6 is supported by a turntable 62 that supports the server rack 3 (or server rack connector 4) in a rotatable state at the lower part of the server rack 3 (or server rack connector 4). You may comprise (refer FIG.5 (C)).

  In the container type data center 1 of the present embodiment, the adjacent server racks 3 (or server rack coupling bodies 4) are arranged by the rotation mechanism 6 (or a combination of the rotation mechanism 6 and a slide mechanism 7 described later) as described above. In the meantime, a common maintenance space 300 necessary for maintenance of the electronic device 50 is secured (see FIG. 1). That is, the server rack 3 (or the server rack coupling body 4) is rotated 90 degrees to a predetermined orientation, so that it is between the adjacent server rack 3 (or the server rack coupling body 4) or the inner wall of the container 2. In the meantime, a shared maintenance space 300 that can be used for either server rack 3 (or server rack connector 4) is secured. The maintenance space 300 is a space having a depth necessary for taking out and attaching the electronic device 50 and the substrate.

<Slide mechanism>
The rotating mechanism 6 may further include a slide mechanism 7 that moves the server rack 3 (or the server rack coupling body 4) in the horizontal direction (see FIGS. 6 and 7). In such a case, it is possible to combine the movement of rotating the server rack 3 (or server rack connector 4) with the movement of sliding (see FIG. 6). According to this, it becomes easy to carry in or carry out the server rack 3 installed in the back | inner side rather than the server rack 3 (or server rack coupling body 4) nearest to the entrance / exit 42.

  The specific configuration of the slide mechanism 7 is not particularly limited. As an example, there is a mechanism in which slide rails 71 are provided on the ceiling and floor of the container 2 and the rotating shaft 61 is slid along the slide rails 71 (see FIG. 7).

<Shielding plate>
The server rack 3 may be provided with a shielding plate 5 that blocks a part of the air flowing in the container 2 (see FIGS. 8 and 9). The shielding plate 5 is provided so as to shield between adjacent server racks 3 or between the server rack 3 and the inner wall of the container 2 and functions as a capping that shields a short circuit of cold air. That is, in the case where there is no such shielding plate 5, there is a possibility that cold air blown out from the air conditioner (air conditioner) 10 may pass through the server rack 3, but the container type data center provided with the shielding plate 5. In 1, since the shielding plate 5 blocks cold air, more cold air flows in the server rack 3. According to this, from the cool air space C (the space formed on the front side of the server rack 3) in the container-type data center 1 to the hot air space H (the rear surface side of the server rack 3), It is possible to prevent the air-conditioning cool air from passing through to the space where the temperature has increased, and to perform temperature adjustment (cooling) of the server rack 3 more efficiently.

  The shielding plate 5 may be formed to be foldable. For example, a folding shielding plate 5 can be provided on the side surface of the server rack 3 near the center in the depth direction of the server rack 3 (see FIG. 10A). In this case, the width of the shielding plate 5 may be equal to or less than half the depth d of the server rack 3 so that the shielding plate 5 can be tilted to one or both of the front direction and the rear direction of the server rack 3 (see FIG. 10 (B)).

  Further, the shielding plate 5 may be provided on the side surface of the server rack 3 so as to be flush with the front surface of the server rack 3 (see FIGS. 11A and 11B). In this case, the width of the shielding plate 5 may be equal to or less than the depth d of the server rack 3, and the shielding plate 5 may be tilted toward the back of the server rack 3 (see FIG. 11B).

<Relationship between air conditioner and passage>
In this embodiment in which the indoor unit 11 of the air conditioner (air conditioner) 10 is installed in the container 2 in the container type data center 1, the server rack 3 is a position that does not interfere with the indoor unit 11 when rotated by the rotating mechanism 6. (See FIG. 12). With this arrangement, when the server rack 3 is rotated during maintenance of the electronic device 50, the server rack 3 does not interfere with the indoor unit 11 (note that there is a possibility that interference may occur). Is indicated by a dashed ellipse in FIG. 12).

  When the slide mechanism 7 is provided in addition to the rotation mechanism 6, the server rack 3 is arranged so as not to interfere with the indoor unit 11 not only when rotating by the rotation mechanism 6 but also when sliding by the slide mechanism 7. Needless to say.

  Further, in the container-type data center 1, when a plurality of indoor units 11 are installed along the longitudinal direction x in the container 2 (see FIG. 8), the rotation shaft 61 of the rotation mechanism 6 is set in the width direction of the container 2. The server rack 3 can be decentered on the opposite side of the center from the indoor unit 11 and the front side of the server rack 3 faces the side where the indoor unit 11 exists (see FIGS. 8 and 12). When arranged in this way, the width of the passage 20 between the front surface of the server rack 3 and the indoor unit 11 can be ensured to be wider.

<Ceiling wiring mechanism>
The container type data center 1 may further include a cable 9 and a cable rack 8. For example, in the container-type data center shown in FIGS. 13 and 14, a cable rack 8 is disposed in the upper part in the container 2, and a cable 9 connected to the electronic device 50 is hung on the cable rack 8. The cable 9 includes various cables such as a power cable and a communication cable. The cable 9 is preferably wired along the rotary shaft 61. In this case, the extra length of the cable 9 is shorter (see FIG. 13).

  The cable rack 8 shown in FIGS. 13 and 14 is a so-called “single side wall fixed type” rack in which one side of the rack is fixed to the inner wall of the container 2. The other side of the rack is supported by being suspended from the ceiling of the container 2 with suspension bolts 25 (see FIG. 14).

  15 and 16 show a ceiling wiring mechanism having another structure. In this ceiling wiring mechanism, a cable rack 8 is suspended from the ceiling of the container 2 near the upper portion of the server rack 3, and a cable 9 connected to an electronic device 50 is hung on the cable rack 8. The cable 9 is routed along the rotation shaft 61, thereby making the extra length of the cable 9 shorter (see FIG. 15).

  As described above, in the container type data center 1 of the present embodiment, the server rack 3 is rotated or further slid around the vertical rotation shaft 61 by the rotation mechanism 6 or in combination with the slide mechanism 7. Can do. According to such a mechanism, the server rack 3 is rotated (or further slid) around the rotating shaft 61 without securing the server rack 3 obliquely in a close state, thereby ensuring the maintenance space 300. In addition, the server rack 3 can be easily returned to the original position after maintenance.

  The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the scope of the present invention. For example, in the above-described embodiment, two server racks 3 are connected to form a set of server rack connections 4, but N server units (N) (N 2 or more) server racks 3 can be connected to form a server rack connector 4.

  In the above-described embodiment, a specific example of the electronic device 50 has not been given. However, for example, all electric / electronic related devices such as a computer, a storage battery, and a power conditioner are included in the electronic device that is the subject of the present invention.

  The present inventor performed various calculations, simulations, simulations, and the like in order to confirm the effects of implementing the present invention. Hereinafter, these results will be described as examples.

(90 degree left, 90 degree left rotation required)

  In addition, it was thought that it was suitable to attach the slide mechanism 7 to the rotating shaft 61 nearest to the entrance / exit 42 of the container 2. In such a case, a passage 20 for passing the server rack 3 installed on the back side of the server rack 3 (or server rack connector 4) provided with the slide mechanism 7 is connected to the server rack 3 (or server rack connector). 4) can be ensured simply by sliding (see FIG. 6, FIG. 12, FIG. 17, etc.).
