  By the way, although the size of the electronic device, for example, the server is standardized, there are several types of large and small. As a rack for storing electronic devices such as servers, it is necessary to have a flexible storage capacity so that any size electronic device can be stored. Instead, it is desirable that the electronic device accommodated as described above can be appropriately and effectively cooled regardless of the size of the electronic device accommodated.

  However, in Patent Document 1, the rack cabinet columns need to be arranged according to the outer dimensions of the information processing apparatus, and therefore the rack cabinet needs to be designed and manufactured for each size of the information processing apparatus. Only an information processing device of a specific size can be stored and cooled, and there is no expandability that can be applied to information processing devices of various sizes, and the cooling action is also limited to a specific size stored in such a rack. The structure can only be secured for the information processing apparatus.

  Further, even in Patent Document 2, although the electronic devices adjacent to each other can be horizontally shifted and fixed to the rails to which the electronic devices are attached, these rails are all formed with equal lengths, and have four corners. In short, the frame that supports the electronic device is arranged at a constant interval by adding the dimensions for shifting the position of the electronic device to the external dimensions of the electronic device. In the end, it is merely configured with a margin for shifting the electronic device of a specific size in the horizontal direction, and even in Patent Document 2, the electronic device of the specific size can only be accommodated and cooled.

The storage portion 6b and the rack body 6a are separately manufactured separately, and the storage portion 6b is formed in a hollow box shape so that the partition plate 8 serves as a top plate, while the rack body 6a is formed in the shape of a hollow cylinder having an open bottom, and the rack main body 6a is mounted on the storage portion 6b and bolted to the rack body 6a by the partition plate 8 which is the top plate of the storage portion 6b. The storage part 6b is partitioned.

  The front plate 3 which is the front surface of the rack body 6a is provided with a front opening for accommodating the electronic device 9 (see FIGS. 6 and 7) in the rack body 6a, and the front opening is opened and closed. The front door 10 is attached through a hinge so as to be opened and closed. In addition, a rear opening is formed in the rear plate 4 serving as the rear surface of the rack body 6a to connect the electronic device 9, and a rear door 11 for opening and closing the rear opening can be opened and closed via a hinge. It is attached. Shield fingers (not shown) sandwiched between the front door 10 and the rear door 11 are attached to the periphery of the front door 10 and the rear door 11 so that electromagnetic waves can enter from around the front door 10 and the rear door 11. And leakage are prevented.

  As shown in FIGS. 1-3, the shift guide 12 is attached to the inner surface of the pair of left and right side plates 5 of the rack body 6a, and the side channel 13 is attached to the rear. The side channels 13 are formed of a channel material, and are attached to the upper and lower portions of each side plate 5 in a pair of upper and lower sides. The pair of upper and lower side channels 13 are bolted to the upper and lower portions of a support member 14 formed of channel material and arranged vertically. The support member 14 is spanned between the side channels 13 in the vertical direction. Then, the rear column 15 formed of the channel material is attached by bolt fastening.

Many are formed at a constant pitch in the direction. Thus, the plurality of electronic devices 9 are supported between the rear columns 15 in an arrangement in which the electronic devices 9 are stacked in multiple stages in the vertical direction.

  On the other hand, the shift guide 12 includes a flat portion 12a formed with a considerable width in the front-rear direction of the rack body 6a, and leg portions that protrude outwardly in an L-shape from both edges in the front-rear direction of the flat portion 12a. 12b, and is formed of a channel material having a length reaching the top plate 1 from the partition plate 8, and the leg portions 12b are spot-welded to the side plate 5 so as to be mounted vertically in the rack body 6a. And on the flat part 12a of these left-right pair of shift guides 12, while supporting the front-end part of the some electronic device 9 accommodated in the rack main body 6a, between these electronic devices 9 and the side plate 5 of the rack main body 6a A pair of left and right support frames are provided to seal the gap between them, specifically, the gap between the front end portion of the electronic device 9 and the flat portion 12a of the shift guide 12 (see FIG. 7).

  The support frame is formed in the rack main body 6a with a length that reaches the top plate 1 from the partition plate 8, and is disposed vertically along the shift guide 12, and a sealing plate 16 having an L-shaped cross section, and a shift It is comprised from the front column 17 formed with the channel material arrange | positioned along the guide 12 and the sealing plate 16 vertically. The sealing plate 16 folded in an L shape has one surface as a mounting base portion 16a and the other surface as a sealing surface portion 16b. The mounting base portion 16a is overlapped with the flat portion 12a of the shift guide 12 to be bolted. In addition to being fastened, the sealing surface portion 16b protrudes inward in the left-right direction of the rack body 6a.

  The front column 17 is superposed on the sealing surface portion 16b of the sealing plate 16 from behind and attached by bolt fastening. The front column 17 is formed in the same manner as the rear column 15. Specifically, the front column 17 has mounting holes b for fastening the front end portions of the plurality of electronic devices 9 respectively in a vertical direction. A large number of pitches are formed, so that the front column 17 supports the front end portions of the plurality of electronic devices 9 arranged in multiple stages in the vertical direction. The plurality of electronic devices 9 having both ends of the front end supported between the pair of left and right front columns 17 are sandwiched between these and the shift guide 12 by the sealing surface portion 16b of the sealing plate 16, and thus the side plate. The space between the 5 inner surfaces is sealed.

  Therefore, inside the rack body 6a, the plurality of electronic devices 9 are supported in a stacked state in the vertical direction, with the front surface portion 9b facing the front door 10 and the rear surface portion 9c facing the rear door 11. The gap between the electronic device 9 and the side plate 5 is sealed with a support frame made up of a sealing plate 16 and a front column 17, and an air supply chamber S is defined in front of the front surface portion 9b, and behind the rear surface portion 9c. The exhaust chamber E is partitioned so that the conditioned air Su and the exhaust Ex are not easily mixed so that the chambers S and E are formed separately from each other (FIGS. 6 and 7). reference). Thus, the conditioned air Su is caused to flow from the air supply chamber S to the electronic device 9 in which an air supply through hole is generally formed in the front surface portion 9b and an exhaust air through hole is formed in the rear surface portion 9c. The exhaust Ex can flow out to the chamber E.

  Some electronic devices 9 have air supply holes formed in the side surface 9a. In this embodiment, the sealing surface portion 16b of the sealing plate 16 positioned between the electronic device 9 and the side plate 5 is penetrated rearward, that is, from the supply chamber S to the exhaust chamber E. Thus, a plurality of openable and closable communication holes 18 through which the conditioned air Su flows from the air supply chamber S to the side surface portion 9a of the electronic device 9 are formed at intervals in the vertical direction (see FIGS. 2 and 7). Each of the communication holes 18 is provided with a cover 19 for opening and closing. Then, by removing the cover 19 as necessary, the conditioned air Su in the air supply chamber S can be guided to the side surface portion 9a of the electronic device 9 and flow into the electronic device 9. .

  In the illustrated example, a case is shown in which the electronic device 9 is not disposed directly below the top plate 1. The electronic device 9 is spanned between the pair of left and right sealing plates 16 in the left-right direction of the rack body 6 a, and A top plate 20 that seals the gap between the electronic device 9 and the top plate 1 and separates the air supply chamber S and the exhaust chamber E is fastened with bolts.

  In particular, the flat portion 12a of the shift guide 12 is attached by bolting the sealing plate 16 so that the sealing plate 16 can be shifted in the front-rear direction so that the volume of the air supply chamber S can be adjusted. A large number of holes c are formed laterally at a constant pitch. In the present embodiment, the side channel 13 is also provided so that the rear column 15 can be moved in accordance with the volume change of the air supply chamber S and also in accordance with the size of the electronic device 9. A large number of mounting holes d for bolting the support member 14 to the support member 14 are formed laterally at a constant pitch. An attachment hole d is formed in the side channel 13 in a wider range than the flat portion 12a, and the rear end portion of the electronic device 9 can be supported by the rear column 15 at various positions.

  On the other hand, the rack main body 6a in which the air supply chamber S and the exhaust chamber E are formed has an air supply portion for introducing the conditioned air Su to the rack main body 6a and an exhaust Ex for discharging the exhaust Ex from the rack main body 6a. And an exhaust part. As long as the air supply unit can introduce the conditioned air Su to the rack body 6a, the air supply section may be provided at any position of the rack body 6a. In the present embodiment, as shown in FIG. The storage unit 6b is configured as an air supply unit. The floor surface 7 on which the storage unit 6b is installed is a floor-blowing air-conditioning type double floor, and an air supply port 21 that communicates with the bottom of the double floor is formed on the bottom plate 2 that is directly installed on the floor surface 7. Thus, the floor-blown conditioned air Su is introduced into the storage portion 6b.

  Further, the exhaust part may be provided at any position of the rack body 6a as long as the exhaust Ex can be discharged from the rack body 6a. In this embodiment, as shown in FIGS. 1 and an exhaust fan 23 which is attached to the top plate 1 and forcibly exhausts the exhaust Ex from the exhaust chamber E toward the exhaust port 22. The exhaust port 22 and the air supply port 21 are provided with an electromagnetic wave shielding member made of a honeycomb shield or a copper net. Of course, an air supply fan may be provided at the air supply port 21.

  On the other hand, an extendable duct 25 for guiding the conditioned air Su introduced from the air supply port 21 to the air supply chamber S is provided between the partition plate 8 of the storage unit 6b and the sealing plate 16 of the support frame. It is done. Furthermore, as shown in FIGS. 1, 3, and 5, the partition plate 8 communicates with the supply chamber S through the duct 25 at the installation position of the duct 25 and supplies air from the supply port 21. The introduction opening 24 through which the conditioned air Su to be circulated is formed. In particular, the introduction opening 24 is formed with a constant size of a considerable size with respect to the shift direction of the support frame including the sealing plate 16.

  As shown in FIGS. 1 to 3, the duct 25 includes three duct pieces 25 a to 25 c that are attached on the partition plate 8 and cover the introduction opening 24 from the exhaust chamber E. That is, a rear duct that is L-shaped in cross-section to seal the rear of the introduction opening 24 and is formed by sealing both left and right ends, is positioned at the rear edge of the introduction opening 24 and is fastened by bolting to the partition plate 8. A piece 25a is formed in a gate shape that rises from both left and right ends, is placed on the front end edge of the rear duct piece 25a so as to protrude forward, and is fixed to the partition plate 8 by bolting and fixing. Similarly to the duct piece 25b, it is formed in a gate shape, and is provided so as to be slidable in the front-rear direction above the center duct piece 25b, and the front end is bolted to the sealing plate 16 and fixed thereto. Composed.

  The length of the duct 25 as a whole can be expanded and contracted by a slidable front duct piece 25c. When the sealing plate 16 is shifted in the front-rear direction, the length of the duct 25 is expanded and contracted accordingly. .

  The duct 25 covers the introduction opening 24 from the exhaust chamber E, while guiding the conditioned air Su flowing into the introduction opening 24 from the rear duct piece 25a to the front duct piece 25c toward the supply chamber S. It is supposed to be. Regardless of the position where the sealing plate 16 or the like is shifted by the duct 25, the conditioned air Su introduced from the double floor under the air supply port 21 is appropriately supplied only to the air supply chamber S. A sufficient amount can be introduced.

  Further, regarding the introduction opening 24, in order to allow all the conditioned air Su to flow into the supply chamber S from the introduction opening 24 having a certain size, the introduction opening 24 has the sealing plate 16 and the like positioned at the foremost position. Sometimes, it is necessary to form it at a location that communicates only with the air supply chamber S, but this reduces the diameter, and when the volume of the air supply chamber S is maximized, a sufficient amount can be obtained smoothly. The conditioned air Su cannot be supplied. On the other hand, if the introduction opening 24 is formed with a large diameter, depending on the shift position of the sealing plate 16 or the like, not all of the conditioned air Su can flow into the air supply chamber S, and a part thereof is directly exhausted from the exhaust chamber E. Can flow into.

  Therefore, in order to always allow a sufficient amount of conditioned air Su to flow into the air supply chamber S, the introduction opening 24 is formed with a large diameter irrespective of the sealing plate 16 to be shifted, and the like. The opening 24 is communicated with the air supply chamber S using the duct 25. In the illustrated example, the introduction opening 24 is also provided with an electromagnetic wave shielding member made of a honeycomb shield 26 or a copper net.

  As shown in FIGS. 1, 3, and 5, a wiring opening 27 is formed in the partition plate 8, and a power supply unit for the electronic device 9 is directly above the wiring opening 27. 28 is mounted, and the power supply section 28 is connected to a power supply line inserted into the storage section 6b from the outside via an electromagnetic shield.

  Next, the operation of the electronic device storage rack 6 will be described. As shown in FIG. 1, FIG. 6 (a) showing a side view of the electronic device 9, and FIG. 6 (b) showing a schematic side cross-section of the electronic device storage rack 6, a plurality of electronic devices are included in the rack body 6a. The apparatus 9 is supported in the rear column 15 and the front column 17 of the support frame with the front side portion 9b facing the front door 10 and the rear side portion 9c facing the rear door 11 in a stacked state in the vertical direction. Stored. The electronic device 9 is usually provided with a fan that exhausts air toward the rear surface portion 9c. By storing the electronic device 9 in the rack body 6a as described above, the supply chamber S and the exhaust chamber are used in the rack body 6a by using the sealing plate 16 and the top plate 20 of the support frame. E is formed separately.

  In particular, when the position of the front column 17 is adjusted in order to change the volume of the air supply chamber S or match the size of the electronic device 9, the sealing plate 16 is moved in the front-rear direction with respect to the shift guide 12. Is shifted to an appropriate position, and bolts are fastened to the mounting holes c of the shift guide 12 at that position. At this time, the top plate 20 attached to the sealing plate 16 also moves, and the front duct piece 25c of the duct 25 also moves at the same time. As a result, the introduction opening 24 is located in front of the sealing plate 16 and the front door 10. An air supply chamber S having an arbitrary volume can be defined in a state where the air supply chamber S is always in communication with the air supply chamber S. Moreover, also about the rear column 15, the rear-end part of the electronic device 9 of various sizes can be supported in arbitrary positions by adjusting the position of the support member 14 with respect to the side channel 13.

  Regarding the cooling of the electronic device 9, the conditioned air Su supplied from under the double floor of the floor blowing air conditioning system reaches the introduction opening 24 from the air supply port 21 through the storage portion 6 b and is further guided to the duct 25 to be supplied. It flows into the gas chamber S. The conditioned air Su that has flowed into the air supply chamber S increases the internal pressure of the air supply chamber S and flows into the electronic device 9 from the air supply through hole of the electronic device front surface portion 9b, thereby exhibiting a cooling action. At the same time, the exhaust Ex from the electronic device 9 flows out to the exhaust chamber E. The exhaust Ex in the exhaust chamber E is discharged from the exhaust port 22. Further, as shown in FIG. 7A showing a plan view of the electronic device 9 and FIG. 7B showing a schematic plane cross section of the electronic device storage rack 6, an electronic device having an air supply through hole in the side surface portion 9a. When the device 9 is accommodated, the conditioned air Su in the air supply chamber S is circulated to the side surface portion 9 a of the electronic device 9 by removing the cover 19 and opening the communication hole 18 of the sealing plate 16. Thus, the cooling action of the electronic device 9 can be ensured.

  Particularly in the electronic device storage rack 6 according to the present embodiment, the inside of the rack body 6a is separated into two chambers S and E for supply and exhaust by the sealing plate 16 and the like. The conditioned air Su can be caused to flow only from the air supply chamber S into the front surface portion 9b of the electronic device 9, and the exhaust Ex can be discharged only from the rear surface portion 9c of the electronic device 9 to the exhaust chamber E. Thus, mixing of the conditioned air Su and the exhaust Ex can be prevented, and the electronic device 9 can be appropriately and effectively cooled.

  In particular, since the rack body 6a is formed with airtightness capable of increasing its internal pressure, the internal pressure of the air supply chamber S can be increased, and the inflow efficiency of the conditioned air Su to the electronic device 9 can be increased. It can be increased and a high cooling effect can be secured. Further, the formation of the rack body 6a with considerable airtightness means that the ventilation holes are not formed in the rack body 6a by punching or the like, thereby improving the rigidity of the rack body 6a and improving the electromagnetic shielding performance. Can be improved.

  Further, by shifting the sealing plate 16 and the like by the shift guide 12, the distance between the electronic device front surface portion 9b supported by the front column 17 and the front door 10 facing this, that is, the volume of the air supply chamber S is increased. When the capacity of the air supply chamber S is desired to be increased, such as when the heat generation amount of the electronic device 9 is large, or when the size of the electronic device 9 is small, the air is supplied in a large volume in the rack body 6a. When the chamber S can be secured, the air supply chamber S having a necessary volume can be appropriately secured while balancing the volume of the exhaust chamber E.

  In other words, the electronic devices 9 of various sizes can be stored, and the flexibility of storage is high, and the rack is supported by the support frame including the sealing plate 16 regardless of the size of the electronic device 9 that is stored. With the air supply chamber S that can be arbitrarily defined in the main body 6a, a sufficient amount of the conditioned air Su can be supplied to the electronic device 9, and high cooling performance can be ensured.

  In addition, the duct 25 allows the air supply port 21 to communicate with only the air supply chamber S regardless of the position of the sealing plate 16 or the like for adjusting the volume of the air supply chamber S. The conditioned air Su can be appropriately supplied to the air supply chamber S.

  In addition, the introduction opening 24 is formed in the partition plate 8 of the storage portion 6b serving as the air supply portion, and the introduction opening 24 and the air supply chamber S are communicated using the duct 25. The introduction opening 24 can be formed with a large constant dimension irrespective of the shift amount of the sealing plate 16 and the like, and hence the volume of the supply chamber S, and the supply chamber S for a sufficient amount of conditioned air Su. Supply to can be guaranteed.

  Further, the rack body 6 is formed of an electromagnetic shielding member, and electromagnetic shielding members such as a honeycomb shield and a shielding finger are provided around the air supply port 21, the exhaust port 22, the introduction opening 24, and the front door 10 and the rear door 11. Therefore, the electronic device 9 can be appropriately protected from harmful electromagnetic waves from the outside.

  Further, since the conditioned air Su is circulated to the side surface portion 9a of the electronic device 9 using the openable / closable communication hole 18, the supply chamber S is made to be the exhaust chamber E if the communication hole 18 is closed. On the other hand, it is possible to reliably cool even the electronic device 9 in which the air supply through hole is formed in the side surface portion 9a by opening it.

  Further, if an air supply fan is provided at the air supply port 21, the conditioned air Su can be forcibly supplied, the internal pressure of the air supply chamber S can be reliably increased, and the electronic device 9 can be reliably and securely operated. It can be cooled efficiently.

  Further, since the exhaust fan 23 is provided at the exhaust port 22, the exhaust Ex can be forcibly exhausted, and the necessary flow of the conditioned air Su can be appropriately generated by the suction action of the conditioned air Su associated therewith, This also makes it possible to cool the electronic device 9 reliably and efficiently.

  FIG. 6B also shows a case where an air supply port 21 is provided in the rear plate 4 of the storage unit 6b, and is not limited to the blown conditioned air Su from the double floor, but the indoor air conditioner. You may make it cool the inside of the rack main body 6a using the air Su.

  Further, in FIG. 6C, which shows a schematic side cross section of the electronic device storage rack 6, an air supply port 21 is formed on the top plate 1 on the rack body 6a side, and an exhaust port 22 is formed on the storage unit 6b side. This is not limited to the case where the conditioned air Su is supplied from below and exhausted from above as in the above embodiment, but the conditioned air Su may be supplied from above and exhausted from below. . In the case of FIG. 6C, an appropriate space 30 is formed between the air supply port 21 and the introduction opening 24, but the top plate 1 is also used as the air supply port 21 and the introduction opening 24. Of course, the duct 25 may be directly attached to the top plate 1. Further, the exhaust Ex may be discharged either under the double floor through the bottom plate 2 or into the room through the rear plate 4.
