It may be configured.
Alternatively, a single rack row may be arranged facing the wall of the server room, an independent space may be formed between the racks, and the air from the air conditioner may be sucked into the space.

  The doors 300 and 400 are front doors and rear doors attached to front and rear entrance portions of the space 800 between the rack rows 100 and 200.

These doors 300 and 400 are physical doors that enter and leave the space 800 and are used for maintenance of equipment such as servers mounted on the rack. However, if they have similar functions, they are air curtains. There may be.
Further, the door may be any one of the front door 300 and the rear door 400, and the structure is not particularly limited. For example, the doors 300 and 400 are provided with windows 301 and 401 made of a transparent member so that the inside can be seen through. The windows 301 and 401 may be made of, for example, polycarbonate resin that also functions as a seal.

  The closing device 500 closes the upper part (ceiling opening) of the hot aisle space 800 formed between the rack rows 100 and 200, and is located on the upper side (ceiling side) of the space. A ceiling closing member 510 for closing the ceiling opening), a ceiling closing member support frame 520 for supporting the member, the ceiling closing member 510 / the ceiling closing member support frame 520, the doors 300 and 400, and the upper portions of the rack rows 100 and 200 And an upper gap closing member 530 (see FIG. 5) and a rack upper gap closing member 530 ′ (see FIG. 6).

  The ceiling closing member 510 is composed of, for example, a plurality of polycarbonate resin plate-like bodies 5101 (see FIG. 4), and constitutes a ceiling member that closes the upper portion (ceiling opening) of the space 800. The polycarbonate resin plate-like body 5101 is preferably made of a transparent material so that the inside of the space 800 can be seen from the outside. Further, the polycarbonate resin plate-like body 5101 may be constituted by a plurality of sheets having a width approximately equal to the rack width, for example. Thereby, attachment and detachment to the ceiling closing member support frame 520 is easy.

Further, as shown in FIG. 1, the ceiling closing member 510 is disposed so as to be positioned on the inner ends of the rack rows 100 and 200 and the upper frame portions of the front door 300 and the rear door 400, and the ceiling closing member 510 is arranged. Thus, it arrange | positions so that the upper part (ceiling opening part) of space 800 may be covered.

  Thus, by arranging so as to cover the upper part (ceiling opening) of the space, the space can be easily closed (shielded).

  The ceiling closing member support frame 520 that supports the ceiling closing member 510 includes, for example, a plurality of connecting square pipes 5201 and a frame fixing pipe 5202 (see FIG. 6).

As shown in FIG. 6, the plurality of connecting square pipes 5201 and the frame fixing pipe 5202 are connected by a frame fixing hardware 5204 and a frame fixing hardware screw 5205, and are integrally configured.
A ceiling closing member 510 is attached to the plurality of connecting square pipes 5201 with fixing screws 5203 or the like (see FIG. 6).

  The upper gap closing member 530 (see FIGS. 5 and 7) closes the upper gap generated between the ceiling closing member 510 (a plurality of polycarbonate resin plate-like bodies) and the doors 300 and 400. It consists of L-shaped or crank-shaped hardware attached to the closing member support frame 520 with screws 5301 or the like. The closing member may not be a hardware as long as confidentiality can be maintained.

  The rack upper gap closing member 530 ′ (see FIG. 6) blocks the rack upper gap generated between the ceiling closing member 510 (plurality of polycarbonate resin plates) and the upper portions of the rack rows 100 and 200. For example, it is made of an L-shaped or crank-shaped hardware attached to the support member 520 with screws 5301 or the like. The closing member may not be a hardware as long as confidentiality can be maintained.

  Normally, the rack upper closing member 530 ′ is configured to close the gap between the rack rows 100 and 200 and the ceiling closing member support frame 520. However, a part of the rack is replaced with a rack having a different height. In such a case, it is effective to use a closing member attached to the ceiling closing member support frame 520. A method for closing the gap between racks due to rack replacement and rack replacement will be described later.

  The suspension device 600 suspends the ceiling closing member 510, and includes a plurality of first long screws 610, a plurality of turnbuckles 620 (see FIG. 2), a plurality of ceiling suspension bolt connection pipes 630, It has a plurality of second long screws 640 and a mounting bracket 650 (see FIG. 5). In terms of reinforcement of the suspension device 600, it is preferable to provide a reinforcing long screw 611 indicated by a one-dot chain line in FIG.

One of the first long screws 610 is attached to the ceiling 910 (see FIG. 2). Further, the other of the long screws 610 is attached to a ceiling suspension bolt connecting pipe 630 with a nut 6301 or the like as shown in FIG. And it is comprised so that the distance of the ceiling 650 and the ceiling suspension bolt connection pipe 630 can be adjusted by rotating the turnbuckle 620.

One end of the second long screw 640 is attached to the ceiling suspension bolt connecting pipe 630 as shown in FIG.
Further, the other of the long screws 640 is attached to the frame fixing pipe 5202 of the ceiling closing member support frame 520 via the mounting bracket 650. Then, the mounting nut 6302 is configured so that the distance between the ceiling suspension bolt connecting pipe 630 and the support frame 520 can be adjusted.

  Here, the ceiling suspension bolt connecting pipe 630 and the ceiling closing member support frame 520 effectively act to close the upper portion (space opening) of the space by the ceiling closing member 510. That is, the ceiling closing member support 520 prevents the ceiling closing member 510 from bending due to its own weight, and the ceiling suspension bolt connection pipe 630 prevents the ceiling closing member 510 and the ceiling closing member support frame 520 from bending due to their own weight.

  As described above, the upper portion (ceiling opening) of the space between the rack rows is closed by the ceiling closing member, and the front and rear portions of the space are closed by the doors, etc., for example, the rack rows arranged in two rows Improving the cooling efficiency of the air-conditioning equipment (air-conditioning system) in the space by sending cold air into the area space between the rack rows from the outside (intake air) and exhausting the hot air in the spaces (area) between the rack rows from below the floor Is possible.

  The free access floor 700 has a discharge port (not shown) for discharging hot air. Note that intake and exhaust may be performed in the reverse flow.

Next, a case where a part of the racks 100 and 200 is replaced will be described. The rack replacement operation is performed as follows, for example.

  For example, when the size of the rack to be replaced is larger than that of the other racks, that is, when replacing a short rack with a tall rack, the turnbuckle 620 attached to the long screw 610 is rotated to support the sealing member 510. Lift 520 upward and lift.

  Accordingly, the ceiling closing member 510 is lifted upward in the rack rows 100 and 200, and the ceiling closing member 510 (support frame 520) is lifted away from the upper end portions of the rack rows 100 and 200. That is, each rack of the rack rows 100 and 200 can be freely moved without being restricted by the ceiling closing member 510, the ceiling closing member support frame 520, and the like.

  That is, the ceiling closing member 510 and the ceiling closing member support frame 520 are lifted and lifted upward using the long screws 610 and the turnbuckle 620 of the suspension device 600 to such an extent that the rack replacement such as removal and installation of the rack is not hindered. .

  By lifting the ceiling closing member support frame, it is possible to take out the rack to be replaced, install a new rack at the taken-out portion, and freely replace the rack. After the replacement, the ceiling closing member 510 and the ceiling closing member support member 520 are suspended downward so as to return to their original positions.

  Further, when the rack to be replaced is smaller in size than the other racks, that is, when a tall rack is replaced with a short rack, the same operation is performed.

  Thus, racks can be easily replaced by suspending the ceiling closing member (polycarbonate resin plate-like body) 510.

  The ceiling closing member 510 may be directly suspended, but the ceiling closing member 510 may be bent due to the weight of the ceiling closing member 510, resulting in a decrease in the closing effect. Therefore, the ceiling closing member 510 is desirably performed via the support frame 520.

  Further, unlike the prior art, the work of removing the fixtures and rail members attached to the rack from the rack is not required at the time of rack replacement work.

  At this time, there is no particular problem when replacing racks of the same size, but when replacing racks of different sizes as described above, the top surface of the rack and the ceiling closing member (polycarbonate resin) are replaced after replacement. A large gap is formed between the (plate-like body) 510 and the ceiling closing member support frame 520. This gap reduces the cooling efficiency.

  Therefore, in such a case, it is generally considered that the upper gap is closed with a filling or the like in the gap, but the operation is not easy.

  According to the present invention, since a rack upper gap closing member 530 ′ is provided on the ceiling closing member support frame 520, a gap is generated between the rack and the ceiling closing member after the rack is replaced. Even so, the upper closing member 530 ′ can close the gap generated between the ceiling closing member and the rack row by simply suspending the suspended ceiling closing member support frame 520, and the gap is easily sealed. be able to.

If the rack upper gap closing member 530 ′ is insufficient, for example, as shown in FIG. 8, the rack replacement portion is covered with, for example, an L-shaped or crank-shaped hardware having the same dimensions as the rack width. By attaching the member 5302 to the ceiling closing member support frame 520 with a fixture 5303 such as a screw, the gap between the racks can be easily closed.

  FIG. 8 shows a case where the rack 107 in the rack row 100 is replaced with a rack 107 ′ that is shorter than the rack. In this case, a large gap is generated between the rack 106 and the rack 108 and between the ceiling closing member support frame 520, but by attaching the closing member 5302 to the ceiling closing member support frame 520 as illustrated, The gap can be easily closed.

  In other words, the capping system can be easily constructed without depending on the size of the rack, and the degree of freedom of rack rearrangement can be increased.

  Further, the vertical movement adjustment of the ceiling closing member 510 may be performed by the following method.

  That is, with the long screw 640, the support frame 520 is adjusted to move upward so that the space between the ceiling suspension bolt connecting pipe 630 and the support frame 520 is narrowed. Thereby, replacement of a tall rack can be easily performed with a degree of freedom.

  In the above embodiment, the two server rack rows 100 and 200 are arranged so as to face each other, and a space is formed between the rack rows. However, one server rack row is opposed to a wall or an alternative. And an independent space with the wall, that is, a space that allows the equipment in and out of the rack to be taken in and out, and the upper part of the space (ceiling opening) is sealed with a ceiling closing device. You may comprise so that a ceiling closing apparatus may be suspended with a suspension apparatus.

  Moreover, even if the ceiling-holding member (plurality of polycarbonate resin plate-like bodies) is configured to hold the ceiling-closing member (plurality of polycarbonate resin plate-like bodies) directly, The structure which hold | maintains indirectly via the ceiling closing member support frame which hold | maintains (resin plate-shaped body) may be sufficient.

  In addition, this invention is not limited to the Example mentioned above, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
