    Description

    FIELD OF THE TECHNOLOGY



    [0001] The present invention relates to the field of communication technology, and more particularly to a container-type data center.

    BACKGROUND OF THE INVENTION



    [0002] Being a mini-type data center solution having a low cost, high integration level, high efficiency, high flexibility, and quick deployment, a movable container-type data center is increasingly adopted by various manufacturers. In order to solve a layout problem of the container-type data center under requests of high density and small maintenance space, different manufacturers propose different layout or maintenance solutions.

    [0003] A container-type data center 10 of the prior art is as shown in FIG. 1. The container-type data center 10 includes a container, and the container includes two side walls 11, and a top wall 12 and a bottom plate 13 connected to the two side walls 11. The container has two rows of cabinets 18 disposed therein, and the cabinets of each row are respectively close to the two side walls 11 and are spaced by a certain distance. The cabinets 18 are face-to-face disposed, and each cabinet 18 is arranged perpendicular to the side wall 11 of the container. The container-type data center 10 further includes a refrigerating unit 15, disposed on the top wall 12 of the container. An air outlet channel 17 is formed between two rows of the cabinets and the side wall 11 of the container. A maintenance channel is formed between the two rows of the cabinets, so as to form an air inlet channel 19. A flowing direction 16 of an air flow in the entire container is as shown in FIG. 1. Hot air generated by devices in the cabinets 18 is exhausted to the air outlet channel 17, cooled by the refrigerating unit 15 disposed on the top wall 12, and then supplied back to the air inlet channel 19 through a fan.

    [0004] During the procedure of implementing the present invention, the inventors find that the prior art at least has the following problems.

    [0005] In the prior art, the container is a standard container with a fixed width size. Due to the arrangement of the two rows of the cabinets, the width of the cabinet placed in the container is limited to the width of the container, that is, only the cabinet with certain width size can be placed, such that when the width size of the container is fixed, a cabinet with a large size cannot be integrated, so the integration level of the data center is not high.

    [0006] WO 2007/082351 A1 relates to an apparatus for providing data processing capabilities.

    [0007] US 2009/241578 A1 relates to a data center cooling system which includes a floor structure defining a below-floor warm-air plenum and an above-floor cool air plenum, a plurality of above-floor computer assemblies arranged to exhaust warmed air into the warm-air plenum.

    [0008] EP 2101017 A2 relates to a portable modular data center cluster according to the preamble of claim 1 and comprising one or more modular containers forming a modular containment structure which provides practical and efficient mobility as the data center can be quickly deployed at a remote site or location.

    [0009] WO 2007/054578 A1 relates to a cooling system for a room containing electronic data processing equipment which comprises a raised floor construction dividing the room into a plenum space underneath the raised floor and a usable space above the raised floor and an air conditioning device for feeding cooled air to the plenum space and a cooling module.

    [0010] US 2007/0135032 A1 relates to a data center with hardware cabinets arranged in multiple rows between cold-air aisles and hot-air aisles. Cold air is supplied into the cold-air aisles by HVAC units through perorated tiles in a raised floor.

    [0011] US 2008/0285232 A1 relates to a cooling system. A data center is arranged in a hot isle/cold isle configuration, wherein computer equipment racks are positioned to draw cooling air from cold isles, and to discharge heated air into hot isles.

    SUMMARY OF THE INVENTION



    [0012] The present invention is directed to a container-type data center cluster, capable of improving an integration level of the data center.

    DETAILED DESCRIPTION OF THE EMBODIMENTS



    [0017] In order to make the objectives, technical solutions, and advantages of the present invention more comprehensible, a detailed description of the present invention is given below by reference to the embodiments and the accompanying drawings. It should be understood that the embodiments are only intended to explain the present invention instead of limiting the scope of the present invention.

    [0018] The embodiment of the present invention provides a cluster of container-type data centers each including a container, at least three rows of cabinets, and data processing devices. The data processing devices are disposed in the cabinets. The at least three rows of the cabinets are disposed in parallel and perpendicular to a long edge of the container. Two neighboring rows of the cabinets of the at least three rows of the cabinets are back-against-back disposed or disposed at intervals, in which when the two neighboring rows of the cabinets are disposed at intervals, a maintenance channel is formed from the space between the two neighboring rows of the cabinets.

    [0019] In the embodiment of the present invention, as the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, each row of the cabinets is not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.

    [0020] FIG. 2(a) is a schematic top structural view of an example of a container-type data center 20. The container-type data center includes at least three rows of the cabinets, but FIG. 2(a) only shows three rows of the cabinets for ease of illustration. The container-type data center 20 includes a container and at least three rows of the cabinets. The at least three rows of the cabinets are disposed in parallel and perpendicular to a long edge 21 of the container, that is, two long side walls of the container. As the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge 21 of the container, the cabinets of two neighboring rows of the at least three rows of the cabinets are back-against-back disposed or disposed at intervals, in which when the cabinets of the two neighboring rows are disposed at intervals, a maintenance channel is formed from the space between the two neighboring rows of the cabinets. The cabinets of the two neighboring rows of the at least three rows of the cabinets may be partially back-against-back disposed, partially disposed at intervals, or are all disposed at intervals. The manner that the two neighboring rows of the cabinets are disposed at intervals includes back-to-back or face-to-face disposition, an air inlet channel is formed from the space between the two neighboring rows of the cabinets being face-to-face disposed, and an air outlet channel is formed from the space between the two neighboring rows of the cabinets being back-to-back disposed. The two neighboring rows of the cabinets being back-against-back disposed are front maintenance cabinets.

    [0021] If only three rows of the cabinets are taken as an example for illustration, as shown in FIG. 2(a), the three rows of the cabinets are respectively a first row of the cabinets 201, a second row of the cabinets 202, and a third row of the cabinets 203. The cabinets of the three rows are disposed at intervals, specifically, the first row of the cabinets 201 and the second row of the cabinets 202 are back-to-back disposed, and the third row of the cabinets 203 and the second row of the cabinets 202 are face-to-face disposed. An air outlet channel 25 is formed from the space between the first row of the cabinets 201 and the second row of the cabinets 202, an air inlet channel is formed from the space between the third row of the cabinets 203 and the second row of the cabinets 202, the air inlet channel is isolated from the air outlet channel in the container, and a maintenance channel 24 is formed from the space among the three rows of the cabinets. In the example, the three rows of the cabinets are all disposed near a long edge of the container, that is, the three rows of the cabinets are disposed along a straight line.

    [0022] It may be known from FIG. 2(a) that in addition to forming the air outlet channel 25 at intervals between the first row of the cabinets 201 and the second row of the cabinets 202, an air outlet channel is formed between the third row of the cabinets 203 and a container end door 28 near the third row of the cabinets 203; and in addition to forming the air inlet channel at intervals between the third row of the cabinets 203 and the second row of the cabinets 202, an air inlet channel is formed between the first row of the cabinets 201 and a container end door 28 near the first row of the cabinets 201. The cabinet air passage is down-in and up-out, front-in and front-out, or down-in and down-out.

    [0023] The data center further includes a refrigerating unit (not shown). The refrigerating unit includes an exchanger and a fan, and may be disposed on a top portion, a side portion, or a lower portion of each row of the cabinets, or may be disposed at intervals between the two neighboring rows of the cabinets. Taking the first row of the cabinets 201 as an example, if the refrigerating unit is disposed on the top portion of the first row of the cabinets 201, hot air (the air flow is indicated by a numeral 29 in FIG. 2) generated by devices in the first row of the cabinets 201 is exhausted to the air outlet channel 25 formed from the space between the first row of the cabinets 201 and the second row of the cabinets 202, cooled by the exchanger in the refrigerating unit, and then supplied to the air inlet channel of the first row of the cabinets 201 through the fan.

    [0024] A partition door configured to isolate the channel from the outside is disposed on an end portion of the air outlet channel and/or the air inlet channel. As shown in FIG. 2(a), a first partition door 205 is disposed between the first row of the cabinets 201 and the second row of the cabinets 202, so as to isolate the air outlet channel 25 from the outside, where the air outlet channel 25 is formed from the space between the first row of the cabinets 201 and the second row of the cabinets 202; and a second partition door 206 is disposed between the third row of the cabinets 203 and the container end door 28 near the third row of the cabinets 203, so as to isolate the air outlet channel from the outside, where the air outlet channel is formed from the space between the third row of the cabinets 203 and the container end door near the third row of the cabinets 203. Through the first partition door 205 and the second partition door 206, the air outlet channels formed in the container, that is, the air outlet channel between the first row of the cabinets 201 and the second row of the cabinets 202 and the air outlet channel between the third row of the cabinets 203 and the container end door 28 near the third row of the cabinets 203, are isolated from the air inlet channels formed in the container, that is, the air inlet channel formed from the space between the third row of the cabinets 203 and the second row of the cabinets 202 and the air inlet channel between the first row of the cabinets 201 and the container end door 28 near the first row of the cabinets 201.

    [0025] In the example, as the three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, each row of the cabinets is not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.

    [0026] A maintenance channel 24 is formed between the other long edge of the container and the three rows of the cabinets, for allowing a maintainer to perform device maintenance. The container further includes two container end doors 28, and it can be understood that one or two of the container end doors 28 may be opened, and the maintainer may enter the container to perform device maintenance after opening the container end door 28.

    [0027] All of the cabinets as shown in FIG. 2(a) are disposed at intervals, or the two neighboring rows of the cabinets are partially back-against-back disposed, and partially disposed at intervals. As shown in FIG. 2(b), the first row of the cabinets 201 and the second row of the cabinets 202 are back-against-back disposed, and the third row of the cabinets 203 and the second row of the cabinets 202 are face-to-face disposed.

    [0028] FIG. 3 is a schematic top structural view of an example of container-type data center according to a second embodiment of the present invention. The structure of this embodiment is similar to the structure of the first embodiment of the present invention, except that the first row of the cabinets 201 and the second row of the cabinets 202 are disposed near one long edge of the container, and the third row of the cabinets 203 is disposed near the other long edge of the container. Through the disposition, the three rows of the cabinets are prevented from being gathered on one side of the container. If the three rows of the cabinets are gathered on one side of the container, the center of gravity of the container is unstable, causing inconvenience during the transportation process. In addition, during the use of the data center, if all the cabinets are gathered on one side of the container, a bottom plate of the container or the foundation may be damaged, thereby reducing the service life of the container.

    [0029] FIG. 4 is a schematic top structural view of an example of a container-type data center according to a third embodiment of the present invention. The structure of this embodiment is similar to the structure of the first embodiment of the present invention, except that the air outlet channels in the container are isolated from the air inlet channels of the outside through the first partition door 205 and the second partition door, and the air inlet channels in the container are isolated from the air outlet channels of the outside through the partition door. Specifically, as shown in FIG. 4, in the example, a third partition door 210 is disposed between the first row of the cabinets 201 and the container end door 28 near the first row of the cabinets 201, so as to isolate the air inlet channel from the outside, where the air inlet channel is formed from the space between the first row of the cabinets 201 and the container end door 28 near the first row of the cabinets 201; and a fourth partition door 212 is disposed between the second row of the cabinets 202 and the third row of the cabinets 203, so as to isolate the air inlet channel from the outside, where the air inlet channel is formed from the space between the second row of the cabinets 202 and the third row of the cabinets 203. In the example, as the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, the cabinets of each row are not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.

    [0030] FIG. 5 is a schematic top structural view of an example of a container-type data center. The structure of this example is similar to the structure of the first example, except that in addition to disposing a first partition door 205 between the first row of the cabinets 201 and the second row of the cabinets 202, and disposing a second partition door 206 between the third row of the cabinets 203 and the container end door 28 near the third row of the cabinets 203, a third partition door 210 is disposed between the first row of the cabinets 201 and the container end door 28 near the first row of the cabinets 201, and a fourth partition door 212 is disposed between the second row of the cabinets 202 and the third row of the cabinets 203, such that the air inlet channels are isolated from the air outlet channels in the container. In the example, as the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, the cabinets of each row are not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.

    [0031] FIG. 6 is a schematic top structural view of an example of a container-type data center. The structure of this example is similar to the structure of the first example, except that the container-type data center further includes a fourth row of the cabinets 204, which are back-to-back disposed with the third row of the cabinets 203. Thus, an air outlet channel is formed from the space between the third row of the cabinets 203 and the fourth row of the cabinets 204, and an air outlet channel is formed from the space between the first row of the cabinets 201 and the second row of the cabinets 202, such that the container only has two air outlet channels. In the container, an air inlet channel is formed from the space between the second row of the cabinets 202 and the third row of the cabinets 203, an air inlet channel is formed from the space between the first row of the cabinets 201 and the container end door 28, and an air inlet channel is formed from the space between the fourth row of the cabinets 204 and the container end door 28. In the example, a first partition door 205 is disposed between the first row of the cabinets 201 and the second row of the cabinets 202, and a second partition door 206 is disposed between the third row of the cabinets 203 and the fourth row of the cabinets 204, so that the air inlet channels are isolated from the air outlet channels in the container. In the example, as the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, the cabinets of each row are not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.

    [0032] FIG. 7 is a schematic top structural view of an example of a container-type data center. The structure of this example is similar to the structure of the second embodiment of the present invention (FIG. 3), except that the container-type data center further includes a fourth row of the cabinets 204, which are back-to-back disposed with the third row of the cabinets 203. Thus, an air outlet channel is formed from the space between the third row of the cabinets 203 and the fourth row of the cabinets 204. The first row of the cabinets 201 and the second row of the cabinets 202 are disposed near one long edge of the container, and the third row of the cabinets 203 and the fourth row of the cabinets 204 are disposed near the other long edge of the container.

    [0033] In the example, a first partition door 205 is disposed between the first row of the cabinets 201 and the second row of the cabinets 202, and a second partition door 206 is disposed between the third row of the cabinets 203 and the fourth row of the cabinets 204, such that the air inlet channels are isolated from the air outlet channels in the container. In the example, as the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, the cabinets of each row are not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.

    [0034] In addition, the third row of the cabinets 203 and the fourth row of the cabinets 204 are staggered from the first row of the cabinets 201 and the second row of the cabinets 202 so as to prevent the four rows of the cabinets from being gathered on one side of the container. If the four rows of the cabinets are gathered on one side of the container, the center of gravity of the container is unstable, causing inconvenience during the transportation process. In addition, during the use of the data center, if all the cabinets are gathered on one side of the container, a bottom plate of the container or the foundation may be damaged, thereby reducing the service life of the container.

    [0035] FIG. 8 is a schematic top structural view of an example of a container-type data center. The structure of this example is similar to the structure of the first example, except that the container-type data center further includes a fourth row of the cabinets 204, which are face-to-face disposed with the first row of the cabinets 201. Thus, an air inlet channel is formed from the space between the first row of the cabinets 201 and the fourth row of the cabinets 204, and an air inlet channel is formed from the space between the second row of the cabinets 202 and the third row of the cabinets 203, so that the container only has two air inlet channels. In the container, an air outlet channel is formed from the space between the first row of the cabinets 201 and the second row of the cabinets 202, an air outlet channel is formed from the space between the third row of the cabinets 203 and the container end door 28, and an air outlet channel is formed from the space between the fourth row of the cabinets 204 and the container end door 28. In the example, a first partition door 214 is disposed between the first row of the cabinets 201 and the fourth row of the cabinets 204, and a second partition door 216 is disposed between the second row of the cabinets 202 and the third row of the cabinets 203, so that the air inlet channels are isolated from the air outlet channels in the container. In the example, as the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, the cabinets of each row are not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container. It can be understood that the first partition door may also be disposed between the first row of the cabinets 201 and the second row of the cabinets 202, and the second partition doors are respectively disposed between the third row of the cabinets 203 and the container end door 28 and between the fourth row of the cabinets 204 and the container end door 28, so as to seal the air outlet channels, such that the air inlet channels are isolated from the air outlet channels in the container through a simple structure.

    [0036] FIG. 9 is a schematic top structural view of a container-type data center used in an embodiment of the present invention. The container-type data center includes a container and at least three rows of cabinets. The at least three rows of the cabinets are disposed in parallel and perpendicular to a long edge 21 of the container, that is, two long side walls of the container. The at least three rows of the cabinets include a first row of the cabinets 201, a second row of the cabinets 202, and a third row of the cabinets 203. The first row of the cabinets 201 and the second row of the cabinets 202 are back-to-back disposed, and the third row of the cabinets 203 and the second row of the cabinets 202 are face-to-face disposed. An air outlet channel 25 is formed from the space between the first row of the cabinets 201 and the second row of the cabinets 202, an air inlet channel is formed from the space between the third row of the cabinets 203 and the second row of the cabinets 202, and the air inlet channel is isolated from the air outlet channel in the container. The at least three rows of the cabinets are arranged from one long edge of the container to the other long edge, that is, the structure of this embodiment is different from the structure of the container-type data center according to the fifth example (FIG. 6) in that, the cabinets are also disposed on the maintenance channel 24, such that the space of the container is fully utilized, the number of the arranged cabinets is increased, and during expansion, it is not necessary to add the containers or occupy additional sites, thereby saving the construction cost of the data center.

    [0037] In an embodiment, a closed space is formed between the first row of the cabinets 201 and the second row of the cabinets 202 and between the two long side walls of the container, so as to isolate the air outlet channel 25 from the outside, where the air outlet channel 25 is formed from the space between the first row of the cabinets 201 and the second row of the cabinets 202; and a closed spaced is formed between the third row of the cabinets 203 and the container end door 28 near the third row of the cabinets 203, so as to isolate the air outlet channel from the outside, where the air outlet channel is formed from the space between the third row of the cabinets 203 and the container end door 28 near the third row of the cabinets 203, so that the air inlet channel is isolated from the air outlet channel in the container. In the embodiment of the present invention, as the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, the cabinets of each row are not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.

    [0038] Two ends of the maintenance channel are the long edge of the container, and an openable and/or removable partition door is disposed on the long edge of one end or two ends. Specifically, an openable first partition door is opened on a long edge 21 between the first row of the cabinets 201 and the second row of the cabinets 202, and an openable second partition door is opened on the long edge 21 between the third row of the cabinets 203 and the container end door 28 near the third row of the cabinets 203. The maintainer may enter the air outlet channel to perform device maintenance through the first partition door and the second partition door.

    [0039] In another embodiment, the container-type data center further includes a fourth row of the cabinets 204. As shown in FIG. 9, the fourth row of the cabinets 204 and the third row of the cabinets 203 are back-to-back disposed, and side walls of two ends of the fourth row of the cabinets 204 are near the two long edges of the container. A closed space is formed between the first row of the cabinets 201 and the second row of the cabinets 202 and between the two long side walls of the container, so as to isolate the air outlet channel 25 from the outside, where the air outlet channel 25 is formed from the space between the first row of the cabinets 201 and the second row of the cabinets 202; and a closed spaced is formed between the third row of the cabinets 203 and the fourth row of the cabinets 204, so as to isolate the air outlet channel from the outside, where the air outlet channel is formed from the space between the third row of the cabinets 203 and the fourth row of the cabinets 204, so that the air inlet channel is isolated from the air outlet channel in the container. In the embodiment, as the at least three rows of the cabinets are disposed in parallel and perpendicular to the long edge of the container, the cabinets of each row are not limited to a width of the container in a width direction, and a cabinet with a large size can be integrated, thereby improving an integration level of the container.

    [0040] In addition, an openable first partition door 205 is opened on a long edge 21 between the first row of the cabinets 201 and the second row of the cabinets 202, an openable second partition door 206 is opened on a long edge 21 between the third row of the cabinets 203 and the fourth row of the cabinets 204, and an openable third partition door 207 is opened on a long edge 21 between the second row of the cabinets 202 and the third row of the cabinets 203, so that the maintainer may enter the air outlet channel and the air inlet channel to perform device maintenance through the first partition door 205, the second partition door 206, and the third partition door 207. As shown in FIG. 9, dashed lines denote states that the partition doors (205, 206, and 207) are opened, and solid lines denote states that the partition doors (205, 206, and 207) are closed.

    [0041] FIG. 10 is a schematic top structural view of a container-type data center cluster according to an embodiment of the present invention. The container-type data center cluster is assembled by a plurality of container-type data centers 20 as shown in FIG. 9. The maintenance channels of the container-type data centers are butt-jointed, or the air outlet channels of the container-type data centers are butt-jointed, and the air inlet channels of the container-type data centers are butt-jointed. Only two container-type data centers 20 are shown, which may be used when a large-scale data center is constructed. The container-type data center 20 in the embodiment of the present invention is similar to the structure of the example of FIG. 9, except that in each container-type data center 20, an openable first partition door 205 is opened on two long edges 21 between the first row of the cabinets 201 and the second row of the cabinets 202, an openable second partition door 206 is opened on the two long edges 21 between the third row of the cabinets 203 and the fourth row of the cabinets 204, and an openable third partition door 207 is disposed on a long edge 21 between the second row of the cabinets 202 and the third row of the cabinets 203, so that the maintainer may enter the air outlet channel to perform device maintenance through the partition doors (205, 206, and 207).

    [0042] In practice, the partition doors on the outside long edge of the container may be closed, and the partition doors between the two container-type data centers 20 are opened or closed, so that the air inlet channels are isolated from the air outlet channels in the container through a simple structure.

    [0043] It can be understood that the partition doors between the two container-type data centers 20 may be removable. After the partition door on the outside long edge of the container is closed, a through channel exists between the two container-type data centers 20, so that the air inlet channels are isolated from the air outlet channels in the container.

    [0044] FIG. 11 is a schematic top structural view of a container-type data center used in another embodiment of the present invention. The container-type data center includes a container, data processing modules, and at least three rows of cabinets. The data processing modules are disposed in the cabinets, the at least three rows of the cabinets are disposed in parallel and perpendicular to a long edge 51 of the container, and two rows of the at least three rows of the cabinets are back-to-back disposed or face-to-face disposed. Side walls at two end portions of each row of the cabinets in the at least three rows of the cabinets are near two long edges of the container, an air inlet channel or an air outlet channel isolated from the air inlet channel is formed from the space between each two rows of the cabinets or between a row of the cabinets and one long edge of the containers; and an openable/removable partition door is disposed on one or two long edges of the container that form each air inlet channel or air outlet channel. As shown in FIG. 11, the at least three rows of the cabinets include a first row of the cabinets 501, a second row of the cabinets 502, and a third row of the cabinets 503. The first row of the cabinets 501 and the second row of the cabinets 502 are back-to-back disposed, and the third row of the cabinets 503 and the second row of the cabinets 502 are face-to-face disposed. An air outlet channel is formed from the space between the first row of the cabinets 501 and the second row of the cabinets 502, an air inlet channel is formed from the space between the third row of the cabinets 503 and the second row of the cabinets 502, and the air outlet channel or the air inlet channel is formed from similar space between the other two cabinets. The air inlet channels are isolated from the air outlet channels in the container.

    [0045] Specifically, the air inlet channels are isolated from the air outlet channels in the container by disposing the openable partition door between each row of the cabinets that form each air inlet channel or air outlet channel, for example, a first partition door 506 is disposed between the first row of the cabinets 501 and the second row of the cabinets 502, so as to isolate the air outlet channel from the outside, where the air outlet channel is formed from the space between the first row of the cabinets 501 and the second row of the cabinets 502; and a second partition door 507 is disposed between the second row of the cabinets 502 and the third row of the cabinets 503, so as to isolate the air inlet channel from the outside, where the air inlet channel is formed from the space between the second row of the cabinets 502 and the third row of the cabinets 503. Similarly, the air outlet channel or the air inlet channel is isolated from the outside by disposing the partition door between each row of the cabinets that form each air outlet channel or air inlet channel, in which the partition door is disposed on one or two long edges of the container.

    [0046] The container-type data center in the embodiment of the present invention can be moved through the movable container, and in another embodiment, the container-type data center can be moved through other movable cases. The cabinet in the embodiment of the present invention is a rack with a standard size of 19 inch. It can be understood that in other embodiments, racks with other standard sizes may also be adopted.
