Description

  The present invention relates to an inter-rack shielding structure in an air conditioning system for a computer room provided with a device housing rack and an air conditioner.

  Conventionally, various air conditioning systems for adjusting the air flow and temperature in a certain space have been proposed. As one of these air conditioning systems, a computer room that adjusts the air flow and temperature around the equipment in the computer room where IT equipment and communication devices that tend to be highly integrated and heat-generating are installed. Air conditioning systems are known. The computer room air conditioning system includes a plurality of equipment storage racks arranged side by side on both sides of the passage, and an air conditioner that is disposed on the side of the equipment storage rack and is opposed to a predetermined space. There is something with.

  In the computer room air conditioning system having such a configuration, when the air conditioner blows cooling air downward, the cooling air is sent to the passage and is sucked into the equipment housing rack from the front. The cooling air is warmed by cooling the equipment housed in the equipment housing rack, and then discharged from the upper surface or the back surface of the equipment housing rack. Air thus warmed and discharged (hot air) flows through the external space of the computer room, is sucked into the air conditioner, and is cooled and blown out again. Thereby, the flow and temperature of the air in the computer room are controlled.

  However, a part of the hot air that has been heated and discharged from the equipment housing rack may be directly returned to the passage from the external space without being sent to the air conditioner. In that case, the hot air recirculated to the passage is sucked into the equipment housing rack again in a heated state. That is, there is a problem that the cooling air supplied from the air conditioner and the hot air discharged from the equipment housing rack are mixed in the passage, thereby reducing the cooling efficiency of the equipment. In order to cope with this, in Patent Document 1, for example, a shield plate such as a plate or a screen is bridged between the both ends of the passage and the upper surfaces of the equipment-accommodating racks facing each other across the passage. The flow of air from the air to the predetermined space is prevented.

  By the way, in order to efficiently cool the equipment housed in the equipment housing rack, it is preferable that adjacent equipment housing racks are brought into close contact with each other and a gap is not formed between them in order to seal the passage. . However, in consideration of construction errors and earthquake resistance, it is necessary to arrange these equipment accommodation racks with an interval of, for example, several mm to several tens mm. Further, depending on the installation conditions, there may be a structure such as a pillar or an uninstalled part such as a rack, and the interval may be about several tens to several tens of centimeters. Therefore, when the gap formed thereby is several mm, sponge rubber is used, and when the gap is relatively large such as several tens of mm or more, the gap is formed by using a shielding plate such as a steel plate processed product. It is blocked and the cooling efficiency is improved.

Japanese Patent No. 3833515

  By the way, the same equipment is not necessarily housed in the same place in the equipment housing rack, and the weight and center of gravity of the equipment housing racks differ from each other depending on the weight of the equipment and the installation location in the rack. It becomes. Also, completely different types of equipment storage racks may be adjacent to each other. In this case, vibrations or swinging behaviors of adjacent equipment housing racks at the time of the occurrence of an earthquake are different, and therefore, between these equipment housing racks, for example, about 50 to 100 mm, in order to avoid interference with each other. It is necessary to form a gap. In addition, when there is a structure such as a pillar between the equipment housing racks, a gap must be formed as described above due to the difference in behavior between the structure and the equipment housing rack when an earthquake occurs. .

  Such a gap cannot be properly closed with sponge rubber because the width of the gap is too large. Then, although the said gap | interval is obstruct | occluded using shielding plates, such as a steel plate processed material, in this case, an excessive load will be applied to this shielding plate depending on the behavior of the apparatus accommodation rack at the time of an earthquake. As a result, the shielding plate, the equipment housing rack, and the structure may be deformed or damaged, and the cooling efficiency may be reduced.

  In view of the above circumstances, the present invention provides a shielding structure between racks that can reliably close a gap between equipment housing racks and can prevent damage due to the behavior of equipment housing racks and structures during an earthquake. And it aims at providing the air conditioning system for computer rooms provided with this shielding structure between racks.

In order to solve the above problems, the present invention proposes the following means.
That is, the inter-rack shielding structure according to the present invention includes a plurality of parallel arrangements on both sides of a passage having an internal space under the floor, and supplies air (heated air) heated from the upper surface or rear surface by supplying air from the front surface. A rack for housing equipment to be discharged and an air conditioner, and the cooling air blown out from the air conditioner flows through the internal space and further from the hole provided in the passage onto the floor of the passage. The air conditioner for the computer room that flows and cools the equipment accommodated in the equipment accommodation rack, and then flows through the space above the equipment accommodation rack and is again sucked into the air conditioner. In the system, there is an inter-rack shielding structure that closes a gap formed between adjacent side surfaces of the adjacent equipment storage racks or between the opposing side surfaces of the equipment storage rack and the structure. A plurality of plate members arranged in the vertical direction in the gap and provided with projections projecting from one surface, and the device housing rack or the structure or the device housing rack and the structure fixed to the device A support member having a long hole that allows the protrusion to be inserted and allows the protrusion to move, and the plate member contacts the adjacent equipment storage rack or the equipment storage rack and the structure. An elastic member is provided in a contact portion .

  According to the inter-rack shielding structure with such a feature, a plurality of plate members arranged in the vertical direction with a plurality of gaps formed between the side surfaces of adjacent equipment housing racks or between the side surfaces of the equipment housing rack and the structure. It is blocked by. As a result, the hot air discharged from the equipment storage rack can be prevented from flowing back into the passage and sucked into the equipment storage rack, and the hot air can be reliably sent to the air conditioner. The cooling efficiency can be improved.

In addition, the plate member has a protrusion, and the protrusion is supported by the support member by being inserted into a long hole of the support rack fixed to the equipment storage rack or structure or the equipment storage rack and structure. The plate member thus made can be moved within the range of the slot size.
As a result, if the width of the gap changes due to vibration or swinging of the equipment rack or structure when an earthquake occurs, the plate member follows the behavior of the equipment rack or structure within the range of the slot. Therefore, the shielding structure and the equipment housing rack or structure do not exert a large load on each other. Therefore, it is possible to prevent the shielding structure, the equipment storage rack, and the structure from being deformed or damaged, and it is possible to maintain the cooling efficiency.
Moreover, although the displacement amount of the equipment storage rack or structure differs between the upper side and the lower side, the plurality of plate members are arranged in the vertical direction, so that each plate member is arranged in the equipment storage rack or structure. Since the individual displacement follows the behavior of the object, it is possible to cope with the displacement due to the behavior of the equipment housing rack or the structure which is different between the upper side and the lower side.
Further, in the inter-rack shielding structure having such a feature, the gap is closed by a plurality of plate members arranged in the vertical direction, so that the same standard plate members can be combined even for gaps having different heights. Can respond.

Further, the plate member is in that it comprises a resilient member and the device housing rack or equipment accommodating rack and structures adjacent to the abutting portion, the plate member and the equipment accommodating rack or structure creation and the elastic member Therefore, the passage can be more reliably sealed and the cooling efficiency can be kept high. In addition, when the equipment housing rack or structure vibrates or swings, the elastic member is elastically deformed, and damage due to applying a load to the plate member can be prevented more reliably.

Further, the inter-rack shielding structure according to the present invention is provided in parallel on both sides of a passage having an internal space under the floor, and air (hot air) heated from the upper surface or the back surface by supplying air from the front surface. A rack for housing equipment to be discharged and an air conditioner, and the cooling air blown out from the air conditioner flows through the internal space and further from the hole provided in the passage onto the floor of the passage. The air conditioner for the computer room that flows and cools the equipment accommodated in the equipment accommodation rack, and then flows through the space above the equipment accommodation rack and is again sucked into the air conditioner. In the system, there is an inter-rack shielding structure that closes a gap formed between adjacent side surfaces of the adjacent equipment storage racks or between the opposing side surfaces of the equipment storage rack and the structure. A plurality of plate members arranged in the vertical direction in the gap and provided with projections projecting from one surface, and the device housing rack or the structure or the device housing rack and the structure fixed to the device And a support member having a long hole into which the protrusion is inserted and allowing the protrusion to move, and the plate member is formed of a plurality of plate materials that overlap and extend .

  Since the plate member is formed of a plurality of plate materials, and the plurality of plate materials can be expanded and contracted by sliding on each other, a plate of any size can be obtained by sliding the plurality of plate materials even in gaps of different sizes. It can be a member. Thereby, it is possible to deal with gaps having different dimensions with the same standard plate member.

In addition, the inter-rack shielding structure according to the present invention includes a plurality of devices arranged side by side on both sides of a passage having an internal space under the floor, and supplies air from the front surface and discharges heated air from the upper surface or the rear surface. The cooling air blown out of the air conditioner flows through the internal space and further flows from the holes provided in the passage onto the floor of the passage.

Hereinafter, an air conditioning system for a computer room according to an embodiment of the present invention will be described with reference to the drawings.
A computer room air conditioning system 100 shown in FIG. 1 is used in a computer room 101 formed in a box shape. First, the computer room 101 will be described. The computer room 101 includes a double floor 2 having an internal space 5 under the floor. The double floor 2 is formed with a passage 4 extending in the longitudinal direction.

  Further, the double floor 2 is formed with a rectangular long hole 8 penetrating in the thickness direction, and a rectangular plate-like hole covering the long hole 8 is formed on the entire periphery of the edge of the long hole 8. An empty panel 7 is fitted. The perforated panel 7 is formed with a plurality of holes penetrating in the thickness direction, whereby the internal space 5 under the floor and the space of the passage 4 are in communication with each other through the plurality of holes. ing.

  Next, the computer room air conditioning system 100 used in the computer room 101 will be described. The computer room air conditioning system 100 includes a rack (equipment housing rack) 3 and a plurality of air conditioners 6 arranged in parallel on both sides of the passage 4.

  The rack 3 is formed in a substantially rectangular parallelepiped box shape and accommodates various devices such as a communication device. A plurality of these racks 3 are arranged along the longitudinal direction of the passage 4 on both sides in the short side direction of the passage 4, that is, on both sides in the passage width direction. In the present embodiment, five racks 3 are juxtaposed on both sides of the passage 4, thereby forming a rack group 9 including five racks 3 on both sides of the passage 4. The rack 3 supplies air in the space of the passage 4 from an air supply port (not shown) formed in the front surface 3b facing the passage 4, and the supplied air is discharged from the upper surface 3a or the rear surface (not shown). (Omitted) is discharged upward or backward.

  Here, the behavior of the rack 3 when the rack 3 vibrates or swings due to an earthquake will be described. In the present embodiment, the rack 3 is fixed on the double floor 2 with its longitudinal direction arranged in the vertical direction. For example, its outer dimensions are about 600 mm to 700 mm in width, 900 mm to 1200 mm in depth, and about 2000 mm in height. Is formed. In this way, the rack 3 is formed so as to extend in the vertical direction, and has a relatively high height and contains a relatively heavy communication device. As shown in FIG. 2, the horizontal displacement amount of the rack 3 increases as it goes upward. That is, the bottom surface of the rack 3 is fixed at the bottom surface fixed on the double floor 2, while the upper surface 3 a is a free end, so that the amount of displacement at the upper surface 3 a increases.

  In the rack group 9 of the present embodiment, as shown in FIG. 3, the four racks 3A on one end side in the longitudinal direction of the passage 4 (the right side in FIGS. 1 and 3) have the same equipment at the same place. By being stored, the weight and center of gravity are equal. Accordingly, these racks 3A exhibit the same behavior during an earthquake and do not interfere with each other. Therefore, the racks 3A are arranged in a state where the side surfaces 3c are in close contact with each other, and the upper surfaces 3a are connected by the fixing member 3d.

  On the other hand, one rack 3B on the other end side in the longitudinal direction of the passage 4 (the left side in FIGS. 1 and 3) is different from the rack 3A in the type and location of the equipment to be accommodated. Is different from the rack 3A. In this case, the adjacent racks 3A and 3B also have different behaviors during an earthquake. Therefore, in order to avoid interference between the racks 3A and 3B at the time of an earthquake, the rack 3B is arranged with a predetermined distance (for example, 50 to 100 mm) from the adjacent rack 3A.

As a result, a gap W extending in the vertical direction is formed between the side surface 3c of the rack 3A and the side surface 3c of the rack 3B, and the passage 4 and the outside of the computer room 101 are in communication with each other. It is said that.
The gap W is provided with a shielding structure (inter-rack shielding structure) 20 for closing the gap W in the entire vertical direction. The configuration of the shielding structure 20 will be described later.

  As shown in FIG. 1, the air conditioner 6 is formed in a substantially box shape, and is disposed on the side of the rack 3 and on one end side in the longitudinal direction of the passage 4. Then, the air conditioner 6 blows out cooling air from the outlet of the lower surface 6b, sucks air flowing in the upper space of the computer room 101 from the suction port of the upper surface 6a, cools the air, and then again It is comprised so that it may blow out from a blower outlet.

  In addition, a wall 13 that divides the space of the passage 4 and the external space is provided at one end in the longitudinal direction of the passage 4, that is, at the end on the air conditioner 6 side. The wall 13 and the air conditioner 6 are arranged with a space therebetween. The wall 13 is provided with a door 13a that can be freely opened and closed.

  By such a wall 13, the space on the passage 4 side and the space on the air conditioner 6 side are blocked, and the cooling air blown out from the perforated panel 7 is directly sucked into the suction port of the air conditioner 6. The so-called short circuit phenomenon is prevented. Therefore, a sufficient amount of cooling air can be supplied to the internal space 5, and the cooling air can be sufficiently sent to the rack 3 that is separated from the air conditioner 6, thereby improving the cooling efficiency. it can. Furthermore, by providing the door 13a, an operator can enter and exit the passage 4 through the door 13a.

  A wall body 14 having a door 14a that can be opened and closed is also provided at the other end in the longitudinal direction of the passage 4, that is, the end portion on the side away from the air conditioner 6. This prevents the hot air discharged from the rack 3 from flowing around the other end of the passage 4 and entering the passage 4. Therefore, even the equipment accommodated in the upper part of the rack 3 on the other end side can be sufficiently cooled. In addition, by providing the door 14a, an operator can enter and exit the passage 4 through the door 14a. Thus, the wall bodies 13 and 14 are arrange | positioned at the both ends of the longitudinal direction of the channel | path 4 as a pair of both-ends shielding part which shields these both ends.

  An upper shield 11 is bridged between the upper surfaces 3 a of the racks 3 arranged on both sides of the passage 4 so as to cover the entire upper side of the passage 4. As a result, the passage 4 and the space above the rack 3 are partitioned, and the hot air discharged from the upper surface 3a or the rear surface of the rack 3 is restricted from flowing into the space of the passage 4, so that the space of the passage 4 Is always filled with the cooling air from the floor of the double floor 2 to the upper shield 11.

  Next, the configuration of the shielding structure 20 in the first embodiment will be described. The shielding structure 20 has a role of closing a gap W formed between the racks 3A and 3B. As shown in FIG. 4, a plurality of plate members 21 and a support member 22 for supporting the plate members 21 are provided. It is composed of

A plurality of plate members 21 are arranged without gaps in the vertical direction of the gap W, and the plate members 21 are not fixed to each other. The plate member is formed of resin or metal.
In order to close the gap, the plate member 21 may have the ends of the plate members 21 adjacent to each other in the vertical direction overlapping each other, and the elastic member in contact with the plate member 21 adjacent to the upper or lower end of the plate member 21 in the vertical direction. May be provided.
The plate member 21 is formed with projections 23 protruding from one surface at the four corners of one surface 21a, and the other surface 21b has a handle portion 24 that can be gripped by the user from the surface 21b. Is provided.
In addition, the installation position and the number of the protrusions 23 and the presence / absence of the handle 24 can be set as appropriate.

The support member 22 is a member having an L-shaped cross section that extends in the vertical direction and is orthogonal to the extending direction. The support member 22 is made of metal, resin, or the like.
One plate member 22a constituting the L-shape is fixed to the side surface 3c of the racks 3A and 3B with screws, double-sided tape or the like, and the other plate member 22b protrudes from the side surface 3c of the rack 3. In the present embodiment, the support member 22 is fixed to the rack 3 so that the other plate member 22 b is flush with the front surface of the rack 3.

A plurality of long holes 25 into which the protrusions 23 of the plate member 21 can be inserted are formed in the other plate material 22b. The long hole 25 is a long hole in the horizontal direction, and the protrusion 23 inserted in the long hole 25 can be displaced in the horizontal direction within the range of the width of the long hole 25. Accordingly, the plate member 21 and the support member can be relatively displaced in the horizontal direction within the range of the width dimension of the long hole 25, that is, the plate member 21 and the rack 3 are horizontally aligned with each other within the range of the width dimension of the long hole 25. Relative displacement is possible in the direction.
The long holes 25 may be long holes in the vertical direction. In this case, the plate member 21 and the rack 3 can be relatively displaced in the vertical direction.
The plurality of long holes 25 formed in the support member 22 may be a mixture of long holes in the horizontal direction and long holes in the vertical direction. In this case, the displacement is not only in the horizontal direction but also in the vertical direction. It becomes possible.
The protrusion 23 may be formed in a rod shape, or may be formed in a hook shape so as not to drop off from the long hole 25 when inserted into the long hole 25.

  In the shielding structure 20 having such a configuration, the projections 23 of the plate member 21 are inserted into the long holes 25, respectively, and the plurality of plate members 21 are installed without gaps in the vertical direction, thereby closing the gap W. be able to. Therefore, it is possible to avoid that the hot air discharged from the rack 3 is recirculated into the passage and sucked into the rack 3 again, and this hot air can be reliably sent to the air conditioner 6, thereby cooling the equipment. Can be kept high.

  Further, when the racks 3A and 3B vibrate and swing when the earthquake occurs and the width of the gap W changes, the plate member 21 and the racks 3A and 3B can be relatively displaced within the width dimension of the long hole 25. Therefore, it is possible to avoid that the plate member 21 is displaced following the behavior of the racks 3A and 3B and the shielding structure 20 and the racks 3A and 3B exert a load on each other. Therefore, it is possible to prevent the shielding structure 20 and the racks 3A and 3B from being deformed or damaged, and to maintain the cooling efficiency.

  In addition, since a plurality of plate members 21 are arranged in the vertical direction in the gap W and the plate members 21 are not fixed to each other, the plate members 21 are displaced following the behavior of the racks 3A and 3B which are different on the upper side and the lower side. can do.

Next, a second embodiment of the present invention will be described.
In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The second embodiment is different from the first embodiment in the configuration of the shielding structure that closes the gap W.

As shown in FIG. 5, in the second embodiment, there is a structure 15 such as a pillar between the racks 3 and 3 of the rack group 9, and the side surface 3 c of the rack 3 and the side surface 15 a of the structure 15 that face each other. A gap W is formed between them. The shielding structure 20 according to the second embodiment shown in FIG. 6 is provided to close the gap.
The structure 15 such as a pillar has a behavior different from that of the rack 3 at the time of an earthquake. Therefore, in order to avoid interference between the rack 3 and the structure 15 due to the behavior, it is preferable to form a gap W of, for example, 50 to 100 mm between the rack 3 and the structure 15. By applying the shielding structure 20 to the gap W, it is possible to prevent the rack 3 and the structure 15 from being deformed or damaged during an earthquake while reliably closing the gap W and improving the cooling efficiency.

As shown in FIG. 6, in the shielding structure 20 of the second embodiment, a support member 32 extending in the vertical direction is fixed to the structure 15, and a plurality of plate members 31 are vertically fixed to the support member 32. Individually supported in an array.
The plate member 31 according to the present embodiment includes two plate members 33a and 33b that are partially overlapped and slidable in the width direction, and a plate-like elastic member 34 that is attached to the side.
In this embodiment, the plate member 31 is not provided with a handle, but the plate member 21 may be provided with a handle 24 as in the first embodiment shown in FIG.

Long holes 35a and 35b that are long in the width direction are formed in the two plate members 33a and 33b, and the long holes 35a and 35b partially or entirely overlap. The plate member 31 can have a predetermined width by sliding the two plate members 33a and 33b. The plate member 31 having a predetermined width is fixed by inserting a fixture 37 into the long holes 35a and 35b in which a part or all of the two plate members 33a and 33b overlap.
The elastic member 34 is formed of rubber, densely arranged horse hair, or the like, and is mounted on the side of the plate member with the surface direction being the same as the surface direction of the plate member 31.
The width of the plate member 31 composed of the two plate members 33 a and 33 b and the elastic member 34 is substantially the same as the width between the racks 3 and 3 adjacent to each other via the structure 15.

The support member 32 is a member fixed to the structure 15, and a plurality of elongated holes 36 extending in the horizontal direction are formed in the vertical direction. A fixing tool 37 is inserted into the long hole 36, thereby supporting the plate member 31.
The fixture 37 inserted into the long hole 36 of the support member 32 can be displaced within the range of the length of the long hole 36. Since the fixture 37 is fixed to the plate member 31, the plate member 31 can be displaced within the length of the long hole 36.
The distal end of the fixing tool 37 may be formed in a hook shape so that it does not easily fall out of the long hole 36.

One fixing member 37 is fixed to one plate member 31, and the plate member 31 is rotatable about the fixing member 37 as a central axis. Therefore, it is possible to prevent the plate members 31 from interfering with each other due to the displacement as described above.
The plate member 31 is always held in a direction in which the elastic member 34 is located on both sides, and the plate member 31 closes the gap W between the adjacent racks 3 and 3 via the structure 15. At this time, the elastic member 34 is in contact with the racks 3 and 3.

In the shielding structure 20 having such a configuration, the plate member 31 and the support member 32 can be displaced relative to each other within the range of the long holes, so that the rack behavior even when the width of the gap W changes at the time of the earthquake occurrence. , The gap W is closed, and the hot air discharged from the rack 3 can be prevented from being recirculated into the passage and sucked into the rack 3 again. (Refer to FIG. 1) can be reliably sent, and the cooling efficiency of the device can be sufficiently ensured.
Further, since the elastic member 34 is disposed on the side of the plate member 31, the elastic member 34 is elastically deformed even when the rack 3 and the plate member 31 collide, and the rack 3 and the plate member 31 are deformed and damaged. Can be prevented.

The embodiment of the present invention has been described above, but the present invention is not limited to this, and can be appropriately changed without departing from the technical idea of the present invention.
For example, in the embodiment, the configuration has been described in which the gap W is formed between the racks 3A and 3B having different centers of gravity and weight, and the shielding structure 20 is provided to close the gap W. However, the present invention is not limited thereto. For example, as shown in FIG. 7, a rack type air conditioner 16 is provided between racks 3 and 3 of the rack group 9, and the side surface 16a of the rack type air conditioner 16 and the side surface 3c of the rack 3 facing each other A configuration may be adopted in which a gap W is formed between them and a shielding structure 20 is provided to close the gap.

  The rack-type air conditioner 16 has a different center of gravity and weight from the rack 3 and thus has a behavior different from that of the rack 3 at the time of an earthquake. Further, vibration is constantly generated by a compressor or the like for cooling the air. Therefore, in order to avoid interference between the rack 3 and the rack-type air conditioner 16 at the time of an earthquake, and further to prevent the vibration of the rack-type air conditioner 16 from being transmitted to the rack 3 and adversely affecting the equipment. It is preferable to form a predetermined gap W between the rack 3 and the rack-type air conditioner 16. By applying the shielding structure 20 of the embodiment in order to close the gap W, it is possible to prevent damage due to an earthquake or failure due to vibration transmission while the gap W is reliably closed.

  Further, for example, as shown in FIG. 8, when there is an uninstalled portion such as a rack between the rack 3 and the rack 3 in the rack group 9, the gap W generated by the uninstalled portion is blocked using the shielding structure 20. May be. Also by this, the cooling efficiency can be improved as described above.

Furthermore, as shown in FIG. 9, various functions may be added to the shielding structure 20. An ITV camera 41 for monitoring the inside of the passage 4, a temperature sensor 42 for detecting the temperature in the passage 4, a monitor control panel 43 indicating the state of each device, An air volume adjusting port 45 for adjusting the air volume, a multipoint sensor 46 capable of detecting temperature, humidity, and pressure at each height position may be provided. Thus, space efficiency can be improved by concentrating various functions.
In addition, in FIG. 9, although the shielding structure 20 by 1st embodiment of this invention is shown, it may be set as the shielding structure by 2nd embodiment instead of the shielding structure 20 by 1st embodiment.

  Further, for example, as shown in FIG. 10, when there is a low rack 17 having a height lower than that of the rack 3 between the racks 3 and 3 of the rack group 9, the side surface 17 a of the low rack 17 and the rack 3 are arranged. The shield W may be used to close the gap W between the side surface 3 c and the gap W between the racks 3 and 3 formed above the overhead rack 17.
