[0010] Each embodiment will be described below with reference to the drawings. In all drawings, identical or equivalent components are denoted by the same reference numerals, and common descriptions are omitted.

[0011] <First Embodiment> Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The equipment housing facility 1 according to this embodiment mainly consists of an equipment housing rack 2, a liquid cooling facility 3, and an equipment housing rack 4, as shown in Figure 1.

[0012] The unit U of the equipment housing facility 1 is composed of one equipment housing rack 2 and one equipment housing rack 4 stacked vertically as indicated by arrow Z. Multiple units U are placed adjacent to each other in the horizontal direction as indicated by arrow X (X1-X2) to form a predetermined length. The direction of arrow Y (Y1-Y2), which is perpendicular to arrow X (X1-X2), indicates the front-to-back direction of the equipment housing facility 1. Furthermore, the frames 5 and 7 of the equipment housing rack 2 and the liquid cooling equipment 3 (see Figure 5) are constructed to have seismic resistance corresponding to the vertical and horizontal accelerations of past earthquakes in order to house the information equipment G, which is important equipment.

[0013] As shown in Figure 5, the equipment housing rack 2 houses multiple information devices G inside a frame 5 made of L-shaped angles 5A arranged in a grid pattern. Multiple boards 6 are installed around the frame 5. The information devices G include image processing devices such as GPUs (Graphics Processing Units) as shown in Figure 4, and are installed in the IT equipment area E within the equipment housing rack 2.

[0014] As shown in Figure 5, the equipment housing rack 4 has a frame 7 made up of L-shaped angles 7A arranged in a grid pattern. This frame 7 of the equipment housing rack 4 is surrounded by multiple plate materials 8 (described later). The equipment housing rack 2 and the equipment housing rack 4 may be formed as a single unit by using common frames 5 and 7, or they may be formed separately and joined together on site. The plate materials 6 and 8 are fixed to the frames 5 and 7 with fasteners 9 such as bolts (see Figure 1), and the layout of the internal space can be freely changed by attaching and detaching them.

[0015] The liquid cooling system 3 has piping 10 through which brine, which serves as cooling water for cooling the information equipment G, can flow. As shown in Figures 1 to 5, the piping 10 includes a first pipe 11 through which brine cooled by a cooling device (not shown) flows, and a second pipe 12 that recovers heat generated in the IT equipment area E within the equipment housing rack 2 and then returns the brine to a heat sink (not shown).

[0016] As shown in Figures 4 and 5, the first piping 11 has a plurality of small pipes 13. These small pipes 13 are connected to a cooling water distributor 14 installed in the upper equipment housing rack 2 for each unit U. The cooling water distributor 14 is provided to distribute the brine supplied from the small pipes 13 to branch pipes 15 that reach the vicinity of the information equipment G in the equipment housing rack 2. In addition, branch pipes 16 that are connected to the branch pipes 15 and have passed through the information equipment G reach the cooling water distributor 14. Furthermore, a small pipe 17 is installed between the cooling water distributor 14 and the second piping 12 to supply the brine, after heat has been recovered, to the second piping 12. That is, the brine, after cooling the information equipment G, is supplied to the second piping 12 via the branch pipes 16, the cooling water distributor 14, and the small pipes 17. Multiple small pipes 17 are installed to return the brine that has passed through the information equipment G in each unit U to the second piping 12.

[0017] Furthermore, the piping 10, including the first pipe 11 and the second pipe 12, is supported by a pipe support section 20, as shown in Figures 1 and 2. The pipe support section 20, as shown in Figures 1, 2, and 5, is composed of a ladder or tray having a grid structure and supports the first pipe 11 and the second pipe 12 along the direction of arrow X in the internal space 4A of the equipment housing rack 4. In Figure 4, reference numeral 18 indicates a flange for connecting pipes, and reference numeral 19 indicates a valve for opening and closing the flow path inside the pipe.

[0018] Meanwhile, various types of wiring 21 are connected to multiple information devices G located within the equipment housing rack 2, as shown in Figure 5. The wiring 21 includes power supply wiring 22 connected to the information devices G and communication wiring 23 connected to the information devices G. The wiring 21 is routed from the information devices G to the upper part of the equipment housing rack 2 in the figure, and then placed on a wiring support section 24 installed on the upper surface of the equipment housing rack 2. The wiring support section 24 is composed of a cable ladder or tray having a grid structure, as shown in Figure 5, and is positioned along the direction of arrow X at the upper part of the equipment housing rack 2.

[0019] Next, a tray structure 30 provided on the equipment housing rack 4 to receive leaked water from the piping 10, etc., will be described. As shown in Figure 5, the tray structure 30 consists of a plurality of plate materials 8 installed on the frame 7 of the equipment housing rack 4, and a plurality of sealing members 31 that fill the gaps between these plate materials 8.

[0020] The plate material 8 is positioned to cover the sides and bottom of the frame 7 of the equipment housing rack 4, and as a whole, it forms a concave space 32 inside. The inside of the plate material 8 is also treated to be water-resistant. The sealing member 31 seals the spaces between adjacent L-shaped angles 7A of the frame 7 and between the L-shaped angles 7A and the plate material 8, allowing leaks from the piping 10, etc. (for example, conductive, corrosive brine) to be stored in the concave space 32 formed inside the plate material 8.

[0021] Furthermore, the concave space 32 formed by the plate material 8 and the sealing member 31 allows for changes in storage capacity according to the amount of water leakage from the piping 10, etc., simply by changing the layout of the plate material 8 installed on the frame 7. In addition, the tray structure 30 is designed so that the plate material 8, which acts as a partition wall, can be removed from the frame 7, making maintenance easier. Moreover, brushes, packings, etc., are used on the first piping 11 and the second piping 12 leading to the information equipment G compartment to prevent brine from inside the equipment housing rack 4 from reaching the information equipment G area.

[0022] Furthermore, the concave space 32 of the receiving tray structure 30 is designed to have a capacity that prevents leakage to the outside even if the entire amount of brine from the cooling system leaks, and is structured so that even in the event of leakage, it does not penetrate the surrounding area and slab and affect the information equipment G on the floor below. In addition, the concave space 32 of the receiving tray structure 30 is installed to penetrate multiple equipment housing racks 4 arranged along the direction of arrow X, and a single receiving tray is formed by a watertight structure via a sealing member 31, so that it can contain a predetermined amount of leaked water.

[0023] Furthermore, the plate material 8 located on the side of the equipment housing rack 4, indicated by arrows X1 and Y1, Y2, is positioned further out than the plate material 6 located on the same side of the equipment housing rack 2, as shown in Figures 5 and 7. This ensures that the tray structure 30 of the equipment housing rack 4 can reliably store any leaked water adhering to the plate material 6 of the equipment housing rack 2 within the concave space 32.

[0024] In particular, the plate material 8 located on the Y2 side of the equipment housing rack 4 is located outside the plate material 6 which forms part of the back door of the equipment housing rack 2, as shown in Figure 7. Therefore, any leaked water that falls when the back door is opened or closed can be reliably stored in the concave space 32 of the tray structure 30. In the equipment housing rack 4, some of the plate materials 8 are open to the outside, so even if the internal volume changes due to temperature changes, cracking of the plate materials 6 and 8 can be prevented.

[0025] Furthermore, as shown in Figure 5, an equipment housing box 40 is installed in the IT equipment area E within the equipment housing rack 2. The equipment housing box 40 is located on the side of the information equipment G, and a distribution board 41 for supplying power to each of the information equipment G is installed inside it. The equipment housing boxes 40 are arranged to be stacked in the direction of arrow Z along the vertical direction, and a storage wall 42 that allows air to pass through is formed on one side along the direction of arrow Z.

[0026] A passage 43 is formed between the storage wall 42 and the side panel 6, along the direction of arrow Z. An air intake hole 44 is formed in the panel 6 of the equipment housing rack 2 located above the passage 43. The air intake hole 44 is a hole that takes in air from a cooling air source 45 for cooling the information equipment G and the distribution board 41.

[0027] On the other hand, an exhaust vent 46 is formed in the plate material 6 located on the lower side of the equipment housing rack 2. The exhaust vent 46 is located on the opposite side of the storage wall 42 from the intake vent 44, as indicated by arrow a inside the equipment housing rack 2, in order to allow the air taken in from the intake vent 44 to pass through the distribution board 41 and the information equipment G. Here, the storage wall 42 also serves to separate the pre-cooling air region 42A where the air taken in from the intake vent 44 accumulates from the post-cooling air region 42B that passes through the information equipment G, and this airflow management can improve the efficiency of the air conditioning. The air supplied from the cooling air source 45 passes through the intake vent 44, the passage 43, the storage wall 42 of the equipment housing box 40, the distribution board 41, and the information equipment G, and after absorbing exhaust heat as it passes through the distribution board 41 and the information equipment G, it is discharged outside the equipment housing rack 2 through the exhaust vent 46.

[0028] In recent years, information equipment G has tended to be high-load, so the aforementioned distribution board 41 is installed on the frame 5 of the equipment housing rack 2. Furthermore, in case the heat generated by the distribution board 41 cannot be removed by the brine supplied from the first pipe 11, the removal of the heat is shared by cooling air supplied from the cooling air source 45.

[0029] On the other hand, the bottom of the equipment housing rack 4 is provided with a unit fixing means 50 for fixing the unit U of the equipment housing facility 1. As shown in Figures 5 to 7, the unit fixing means 50 consists of a floor fixing part 52 fixed to the bottom of the frame 7 in the equipment housing rack 4 and having an elongated anchor fixing hole 51 in the center, and an anchor 53 inserted through the anchor fixing hole 51 of the floor fixing part 52.

[0030] The anchor fixing holes 51 of the floor fixing portion 52 allow the fastening position of the anchor 53 to the concrete slab floor 60, or the fixing position of the equipment housing rack 4 to the anchor 53, to be changed in the direction of arrow D, thereby preventing the anchor 53 from interfering with the reinforcing bars 61 inside the concrete slab floor 60. After passing through the anchor fixing holes 51 of the floor fixing portion 52, the anchor 53 is driven into the casting holes 62 in the concrete slab floor 60, thereby fixing the equipment housing rack 4 and the equipment housing rack 2 installed on its upper part to the concrete slab floor 60.

[0031] Although not shown in the figure, a waterproof packing is interposed between the anchor 53 and the floor fixing part 52 to prevent water leakage from reaching the concrete slab floor 60. The anchor fixing hole 51 has an anisotropic shape that extends in one direction along the upper surface of the concrete slab floor 60. For example, it may be oriented in a specific direction for each unit U depending on the installation situation of the reinforcing bars 61 inside the concrete slab floor 60.

[0032] Furthermore, in the equipment housing facility 1 described above, multiple equipment housing racks 4 for housing liquid cooling equipment 3 are arranged below multiple equipment housing racks 2, and piping 10 is arranged to extend across these equipment housing racks 4. As a result, the equipment housing facility 1 has the effect of making the information equipment G located in the upper equipment housing racks 2 less susceptible to the effects of liquid leakage. Therefore, the equipment housing facility 1 can suppress the effects of liquid leakage on the information equipment G located in the upper equipment racks.

[0033] Furthermore, in the above-mentioned equipment housing facility 1, since multiple equipment housing racks 4 have a receiving tray structure 30, all leaked water can be stored in the receiving tray structure 30, and it is also possible to prevent other information equipment G from being affected by the leaked water.

[0034] Furthermore, the equipment housing facility 1 has a tray structure 30 which includes multiple plate materials 8 and multiple sealing members 31 that fill the gaps between the multiple plate materials 8. This allows water leakage to be contained inside the equipment housing rack 4 and prevented from leaking to the outside, thereby minimizing the impact on other information equipment G.

[0035] Furthermore, in the above-mentioned equipment housing facility 1, a portion of the sealing member 31 of the tray structure 30 is installed between adjacent (adjacent in the direction of arrow X) L-shaped angles 7A that constitute the frame 7 of the equipment housing rack 4. As a result, in the above-mentioned equipment housing facility 1, the sealing member 31 can adjust the gap between the equipment housing rack 2 and the equipment housing rack 4 between the units U, while also preventing water leakage from between the units U.

[0036] Furthermore, in the above-mentioned equipment housing facility 1, storage walls 42 for equipment housing boxes 40 capable of housing a distribution board 41 that supplies power to each of the multiple information devices G are formed within the equipment housing rack 2 in each unit U. As a result, in the above-mentioned equipment housing facility 1, the distribution board 41 is less susceptible to the effects of liquid leakage, and the flow of cooling air can be managed by utilizing the storage walls 42 of the multiple equipment housing boxes 40.

[0037] Furthermore, the equipment housing facility 1 is further equipped with a cooling air source 45 capable of supplying air from above the multiple storage walls 42 toward the multiple equipment housing racks 2. The multiple storage walls 42 separate the air before cooling the multiple information equipment G from the air after cooling the multiple information equipment G. In other words, these multiple storage walls 42 also serve to separate the pre-cooling air region 42A where air taken in from the intake holes 44 accumulates from the post-cooling air region 42B that passes through the information equipment G, thereby improving air conditioning efficiency through such containment airflow management.

[0038] Furthermore, the equipment housing facility 1 is further equipped with a wiring support section 24 on the storage wall 42 that supports power supply wiring 22 connected to multiple information devices G and communication wiring 23 connected to multiple information devices G, so that the power supply wiring 22 and communication wiring 23 are less susceptible to water leakage. As a result, the equipment housing facility 1 can suppress the effects of water leakage on the power supply wiring 22 and communication wiring 23 located in the upper section. Moreover, even if the equipment housing facility 1 is installed in a simple building where it is not possible to suspend cable ladders, baskets, etc. from the ceiling for wiring power and communication, the wiring route can be secured by the wiring support section 24 installed on the equipment housing rack 2. As a result, the equipment housing facility 1 can realize an inexpensive packaged installation structure for information devices G by configuring the unit U described above.

[0039] Furthermore, in the equipment housing facility 1, a floor fixing section 52 is provided on the frame 7 of the equipment housing rack 4, which has at least one anchor fixing hole 51 into which an anchor 53 can be driven, avoiding multiple reinforcing bars 61 located within the concrete slab floor 60. This allows the equipment housing rack 4 to be easily fixed to the concrete slab floor 60 via the floor fixing section 52 in the equipment housing facility 1.

[0040] Furthermore, in the equipment housing facility 1 described above, at least one anchor fixing hole 51 provided in the floor fixing portion 52 is arranged so as to be aligned in one direction along the upper surface of the concrete slab floor 60 (in this example, arranged in the direction of arrow D shown in Figure 6). As a result, in the equipment housing facility 1 described above, the equipment housing rack 4 can be easily moved along the anchor fixing hole 51 according to the installation status of the reinforcing bars 61 in the concrete slab floor 60, and a predetermined level of seismic resistance can be maintained.

[0041] Furthermore, in the equipment housing facility 1, at least one anchor fixing hole 51 has an anisotropic shape that extends in one direction along the upper surface of the concrete slab floor 60, which facilitates the installation of the equipment housing rack 4 on the concrete slab floor 60.

[0042] (Modification Example 1) In the above embodiment, in order to prevent the leaked brine from the pipe 10 or the like from flowing out to the outside within the concave space 32 of the tray structure 30, a liquid absorbent 70 as shown in FIG. 7 may be installed. At that time, the liquid absorbent 70 may cover the entire bottom surface of the concave space 32 or a part of the bottom surface according to the assumed amount of brine.

[0043] (Modification Example 2) The seal member 31 of the tray structure 30 shown in the above embodiment may appropriately change its thickness for the clearance adjustment of the equipment storage rack 4 of the unit U.

[0044] (Modification Example 3) In the above embodiment, four floor fixing parts 52 are provided at the bottom of the frame 7, and anchor fixing holes 51 are provided in each of the floor fixing parts 52. However, at least one anchor fixing hole 51 is sufficient, and it is not limited to providing a plurality of them. Further, the anchor fixing holes 51 may be provided at three locations forming a planar shape in order to avoid contact between the anchor 53 and the reinforcing bar 61 in the concrete slab floor 60 and to keep the fixing strength of the anchor 53 at a predetermined value or more.

[0045] (Modification Example 4) In the above embodiment, the long-hole-shaped anchor fixing holes 51 are arranged in one direction along the arrow D direction, but their directions and shapes can be variously changed according to the installation state of the reinforcing bar 61.

[0046] (Modification Example 5) In the above embodiment, the equipment storage rack 4 is in direct contact with the concrete slab floor 60, but it is not limited to this, and it may be provided with casters in consideration of future movement, and a leveling bolt as indicated by reference numeral 71 in FIG. 4 may be interposed for horizontal adjustment.

[0047] <Second Embodiment> Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 8, the equipment storage facility 100 shown in the present disclosure includes a plurality of equipment storage racks 101, a liquid cooling facility 102, and a plurality of equipment storage racks 103.

[0048] A plurality of equipment storage racks 101 are configured to accommodate a plurality of information devices.

[0049] And, in the equipment storage facility 100 as described above, a plurality of equipment storage racks 103 for accommodating the liquid cooling equipment 102 are arranged below the plurality of equipment storage racks 101, and the pipe 104 is arranged so as to extend across these equipment storage racks 103. Thus, according to the equipment storage facility 100, the influence of liquid leakage can be suppressed for the information devices located in the upper stage.

[0050] <Third Embodiment> Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 9, an equipment storage facility 200 shown in the present disclosure includes a plurality of equipment storage racks 201, a liquid cooling equipment 202, and a plurality of equipment storage racks 203.

[0051] A plurality of equipment storage racks 201 are configured to accommodate a plurality of information devices.

The plurality of equipment storage racks 203 are located below the plurality of equipment storage racks 201 and are configured to accommodate the liquid cooling equipment 202. Further, the equipment storage rack 203 is configured to have a tray structure 205.

[0052] And, in the equipment storage facility 200 as described above, since the plurality of equipment storage racks 203 have the tray structure 205, the tray structure 205 can store the leaked water. Thus, according to the equipment storage facility 200, the influence of liquid leakage can be suppressed for other information devices.
