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. In addition, depending on the installation conditions, there may be a structure such as a pillar, or there may be an uninstalled part such as a device housing rack, and the interval may be 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, depending on the behavior of the equipment accommodation rack at the time of an earthquake, an excessive load will be applied to this shielding plate. 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 addition, when the earthquake has stopped, it takes time to restore the shield that has been displaced to the initial position and repair / replace the damaged part, which reduces the cooling efficiency during that time. There was a problem that.

  In view of the above circumstances, the present invention can reliably close the gap between the equipment accommodation racks or the gap between the equipment accommodation rack and the structure, and also provide the equipment accommodation rack and structure in the event of an earthquake. It is an object of the present invention to provide an inter-rack shielding structure and a computer room air conditioning system that can prevent damage due to behavior and can automatically return to close the gap again at the end of an earthquake.

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 devices arranged side by side on both sides of a passage having an internal space below 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. In a computer room air conditioning system in which cooling air cools a device housed in the device housing rack and then flows through a space above the device housing rack and is sucked back into the air conditioner. An inter-rack shielding structure that closes a gap formed between the opposing side surfaces of the matching equipment accommodating racks or between the opposing side surfaces of the equipment accommodating rack and the structure, Of extending over the vertical direction, are a stretchable in the opposite direction of the side, includes a first shielding plate arranged on one of the side surface side, and a second shielding plate arranged on the other of the side surface The first shielding plate and the second shielding plate are connected to each other so as to be relatively movable in the opposing direction of the side surfaces, and at least a part of the second shielding plate is accommodated in the first shielding plate, The first shielding plate is fixed to one of the side surfaces, and has an urging member that urges the second shielding plate toward the other side surface inside the first shielding plate, The second shielding plate is divided into a plurality of parts in the vertical direction .

  According to the shielding structure between racks having such a feature, the shielding structure closes a gap formed between the side surfaces of adjacent equipment housing racks or between the side surfaces of the equipment housing rack and the structure. The hot air exhausted from the equipment 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 to improve equipment cooling efficiency. Can be made.

Further, when the width of the gap changes due to the vibration or swinging of the equipment-accommodating rack or structure when an earthquake occurs, the shielding structure expands and contracts according to the size of the width. That is, since the shielding structure expands and contracts following the behavior of the equipment housing rack or structure, 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 housing rack, and the structure from being deformed or damaged, and it is possible to maintain high cooling efficiency.
Furthermore, the gap formed between the pair of side surfaces can be reliably closed by the first shielding plate and the second shielding plate. In addition, when the equipment housing rack or structure vibrates or swings due to an earthquake or the like, the first shielding plate and the second shielding plate move relative to each other in the opposite direction of the side surface. The damage which arises when a 2nd shielding board applies a load mutually can be prevented.
Further, since the shielding structure is a nesting type in which the second shielding plate is accommodated in the first shielding plate, the first shielding plate and the second shielding plate are securely closed while ensuring the sealing of the passage. The two shielding plates can be easily moved relative to each other in the opposing direction of the side surfaces. As a result, it is possible to more reliably prevent the shielding structure, the equipment-accommodating rack, and the structure from being deformed or damaged, and maintain the cooling efficiency.
Furthermore, the gap between the side surfaces can be reliably closed by urging the second shielding plate toward the other side surface from the inside of the first shielding plate. When the width of the gap changes during an earthquake, the second shielding plate protrudes according to the urging force of the urging member, or moves back into the first shielding plate against the urging force. As a result, the shielding structure can be flexibly expanded and contracted in accordance with the behavior of the equipment housing rack or the structure, so that it is possible to prevent damage from occurring while closing the gap even during an earthquake. Further, when the earthquake is settled, the second shielding plate closes the gap again by the urging force of the urging member, so that the automatic return can be achieved.
In addition, since the lower part of the equipment storage rack or structure is placed or fixed on the floor, the equipment storage rack and structure behave in a tilted manner during an earthquake. It shows a behavior in which the amount of displacement in the horizontal direction increases as it goes to. In this regard, in the present invention, since the second shielding plate is divided in the vertical direction, the second shielding plate is divided in accordance with the amount of horizontal displacement at each height position of the equipment housing rack and the structure. Each second shielding plate protrudes and retracts. This makes it possible to reliably close the gap in a flexible manner corresponding to the difference in the width of the gap in the vertical direction.

By fixing the first shielding plate and the second shielding plate to the side surfaces facing each other, the shielding structure can be made robust .

  The computer room air conditioning system according to the present invention includes any one of the above-described shielding structures between racks.

  According to the computer room air conditioning system of the present invention, since the shielding structure can be expanded and contracted in the opposite direction of the side surface, the gap between the equipment accommodation racks or the gap between the equipment accommodation rack and the structure is provided. Can be reliably closed. In addition, it is possible to prevent damage due to the behavior of equipment housing racks and structures during an earthquake.

Hereinafter, a shielding structure between racks and 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 gap W and the outside of the passage 4 in the computer room 101 are formed by the gap W. The side is in communication.
A shielding structure (inter-rack shielding structure) 20 for closing the gap W over the entire upper and lower sides is provided in the gap W. 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 present embodiment will be described. The shielding structure 20 has a role of closing a gap W formed between the racks 3A and 3B, and includes a first shielding plate 21 and a second shielding plate 22 as shown in FIG. .

  The first shielding plate 21 is a rectangular plate-like member extending over the entire vertical direction of the gap W, and the base end portion 21a is attached to the side surface 3c (one side surface 3c) of the rack 3B via the first fixing plate 23. It has been. Accordingly, the first shielding plate 21 is integrally fixed to the side surface 3c of the rack 3B so as to protrude toward the rack 3A. The inside of the first shielding plate 21 is hollow, and an opening extending in the entire vertical direction is formed at the end on the rack 3A side, that is, the tip 21b of the first shielding plate 21. Yes.

  The second shielding plate 22 is a rectangular plate-like member that extends over the entire vertical direction of the gap W and is slightly smaller than the first shielding plate 22, and has a base end portion 22 a that is a second fixed plate 24. Is attached to the side surface 3c (the other side surface 3c) of the rack 3A. Thus, the second shielding plate 22 is integrally fixed to the side surface 3c of the rack 3A so as to protrude toward the rack 3B. The end of the second shielding plate 22 on the rack 3B side, that is, the front end 22b of the second shielding plate 22 is inserted from the opening of the first shielding plate 21 and is inserted into the first shielding plate 21. It is stored.

  As a result, the first shielding plate 21 and the second shielding plate 22 fixed so as to face the side surfaces 3c of the racks 3A and 3B are connected to each other so as to be relatively movable in the facing direction of the side surfaces 3c. That is, the shielding structure 20 of the present embodiment is a nested type in which a part of the second shielding plate 22 is accommodated in the first shielding plate 21.

  For example, as shown in FIG. 5, the upper corner portion 22 c of the distal end portion 22 b of the second shielding plate 22 housed in the first shielding plate 21 has an upper end portion 22 b and an upper end portion 22 d of the second shielding plate 22. It is preferable that it is made into the R shape which connects smoothly.

  In the shielding structure 20 having such a configuration, the first shielding plate 21 and the second shielding plate 22 are connected by accommodating the tip 22b of the second shielding plate 22 in the first shielding plate 21. As a result, the gap W is closed over the entire vertical direction. 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 first shielding plate 21 and the second shielding plate 22 correspond to the side surface 3c according to the size of the width. Move in the opposite direction. Thereby, it can avoid that the 1st shielding board 21 and the 2nd shielding board 22 exert a load mutually, and shielding structure 20 itself can be expanded-contracted according to the behavior of rack 3A, 3B. 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.

Further, in the present embodiment, since the first shielding plate 21 and the second shielding plate 22 are fixed to the side surfaces 3c facing each other, the shielding structure 20 can be made robust and the gap W is closed. The state can be ensured.
Further, since the corner 22c of the tip 22b of the second shielding plate 22 housed inside the first shielding plate 21 has an R shape, the first when the racks 3A and 3B vibrate and swing. The shielding plate 21 and the second shielding plate 22 can be smoothly moved relative to each other. Thereby, the deformation | transformation and damage of the shielding structure 20 and rack 3A, 3B can be prevented more reliably.

  In the shielding structure 20 of the first embodiment, both the first shielding plate 21 and the second shielding plate 22 are fixed to the side surface 3c, but only one of them is fixed to the side surface 3c. There may be. Even in this case, since the tip 22b of the second shielding plate 22 is inserted into the first shielding plate 21, the gap W can be reliably closed without releasing the connection state between the two. Can do.

  Further, instead of firmly fixing the first fixing plate 23 and the first shielding plate 21 or the second fixing plate 24 and the second shielding plate 22, for example, by pin fixing, the first shielding plate 21 and the second shielding plate 21. By enabling the shielding plate 22 to move in the depth direction, it not only follows the vibrations and swings in the opposite direction of the side surface 3c when an earthquake occurs, but also follows the displacement when it vibrates and swings in the horizontal direction. It can be made. At this time, the cross-sectional shape of the base end portion 21a of the first shielding plate 21 and the base end portion 22a of the second shielding plate 22 may be a substantially semicircular shape so that displacement as a pin fulcrum is possible. . Alternatively, a flexible material such as rubber may be laid on the base end portion 21 a of the first shielding plate 21 and the base end portion 22 a of the second shielding plate 22.

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 20 that closes the gap W.

  As shown in FIG. 6, the shielding structure 20 of the second embodiment includes a slide box (first shielding plate) 31, a slide part (second shielding plate) 32, and a spring member (biasing member) 33. ing.

  The slide box 31 is a rectangular plate-like member extending across the entire vertical direction of the gap W, and the base end portion 31a is attached to the side surface 3c (one side surface 3c) of the rack 3B via the fixed plate 34. Thereby, the slide box 31 is integrally fixed to the side surface 3c of the rack 3B so as to protrude toward the rack 3A.

  In addition, a plurality of rectangular holes 31 c are formed at the end of the slide box 31 on the rack 3 </ b> A side, that is, at the tip 31 b of the slide box 31. The rectangular hole portion 31c is a concave portion that is recessed in a substantially rectangular shape from the distal end portion 31b, and a plurality of rectangular hole portions 31c are formed so as to be arranged in parallel in the vertical direction of the distal end portion 31b.

  The slide part 32 is a plate-like member extending in the vertical direction, and a plurality of slide parts 32 are provided so as to be accommodated in the respective rectangular hole portions 31 c of the slide box 31. The slide part 32 has an external shape that can be slidably inserted into the rectangular hole 31c. The surface facing the rack 3A side, that is, the entire front end surface 32a of the slide part 32 is, for example, rubber or resin. The elastic material 35 which consists of is provided.

  The spring member 33 is disposed in the rectangular hole portion 31 c of the slide box 31, and connects the wall surface in the rectangular hole portion 31 c and the rear end surface 32 b of the slide part 32. Thereby, the slide part 32 is urged | biased by the said spring member 33 in the direction protruded from the rectangular hole part 31c, ie, the rack 3A side.

  As a result, the shielding structure 20 of the present embodiment is relative to the distal end portion 31b of the slide box 31 so that the slide part 32 arranged so as to be divided into a plurality of parts vertically projects toward the rack 3A side. It is configured to move.

  In the shielding structure 20 having such a configuration, the front end surfaces 32a of the plurality of slide parts 32 protruding from the slide box 31 come into contact with the side surface 3c of the rack 3A, thereby closing the gap W over the entire vertical direction. it can. As a result, it is possible to avoid that the air blown out from the rack 3 is recirculated into the passage and sucked into the rack 3 again, and this air can be reliably sent to the air conditioner 6 to improve the cooling efficiency of the equipment. It can be secured sufficiently.

  Further, when the racks 3A and 3B vibrate and swing when the earthquake occurs and the width of the gap W changes, the slide part 32 protrudes according to the bias of the spring member 33, or moves backward against the bias. To do. As a result, the shielding structure 20 itself expands and contracts following the behavior of the racks 3A and 3B. Therefore, as in the first embodiment, deformation and breakage of the shielding structure 20 and the racks 3A and 3B can be prevented, and cooling efficiency is improved. Can be maintained. Furthermore, when the earthquake stops, the slide part 32 automatically returns to the initial state by the urging of the spring member 33, so that automatic recovery can be achieved.

  Further, in the present embodiment, the plurality of slide parts 32 provided independently in the vertical direction are movable relative to the slide box 31, so that the horizontal displacement of each height position of the racks 3 </ b> A and 3 </ b> B is achieved. The slide parts 32 can be displaced in the opposing direction of the side surface 3c according to the amount. As a result, the gap can be reliably closed by flexibly responding to the difference in the width of the gap in the vertical direction due to the inclination of the racks 3A and 3B.

  Further, according to the difference in displacement in the height direction, the depth of relative movement between the slide box 31 and the slide part 32 is increased at the upper portion where displacement is large, and the depth of relative movement is decreased at the lower portion where displacement is small. May be.

Next, a third embodiment of the present invention will be described.
In the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The third embodiment is different from the first embodiment in the configuration of the shielding structure 20 that closes the gap W.

  As shown in FIG. 7, the shielding structure 20 of the third embodiment includes a nesting type first shielding plate 21 and a second shielding plate 22 as in the first embodiment. A pair of support portions 25 for supporting the plate 21 and the second shielding plate 22 are provided.

  That is, the support part 25 is the first shielding plate 21 or the second standing state at the front end of the support plate 25a disposed on the floor surface extending in the horizontal direction along the side surfaces 3c of the racks 3A and 3B. The lower end of the shielding plate 22 is fixed. Also, the lower end of the support bar 25b extending toward the passage 4 as it goes upward is fixed to the rear end side of the support plate 25b, and the front end of the support bar 25b is fixed to the first shield plate 21 or the second shield. It is fixed to the back surface of the plate 22. By the support portion 25, the standing state of the first shielding plate 21 and the second shielding plate 22 is maintained.

  In the shielding structure 20 having such a configuration, as in the first embodiment, since the gap W is closed by the first shielding plate 21 and the second shielding plate 22 which are nested, the rack 3A, When 3B vibrates and swings, the first shielding plate 21 and the second shielding plate 22 move relative to each other in the facing direction of the side surface 3c. That is, since the shielding structure 20 is extended and contracted, it can be installed according to the size of the gap W, and damage to the shielding structure 20 and the racks 3A and 3B can be avoided.

  In addition, while the relative movement can be easily performed in this way, the standing state of the first shielding plate 21 and the second shielding plate 22 is surely held by the support portion 25, so that the shielding structure 20 itself is robust. Can be. Thereby, even if the width of the gap W is wide, damage can be avoided by relative movement of the first shielding plate 21 and the second shielding plate 22 during an earthquake while reliably closing the gap.

  In addition, you may fix the 1st shielding board 21 and the 2nd shielding board 22 so that relative movement is impossible, for example using a screw | thread. In this case, it is impossible to expand and contract in accordance with the change in the width of the gap W, but the shielding structure 20 itself can be made more robust and integrated with an adjacent rack. It is possible to prevent falling down during an earthquake.

Next, a fourth embodiment of the present invention will be described.
In the fourth embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The fourth embodiment is different from the first embodiment in the configuration of the shielding structure 20 that closes the gap W.

  As shown in FIG. 8, the shielding structure 20 of the fourth embodiment includes a cylindrical body 26 made of an elastic material such as rubber or resin. The cylindrical body 26 has a hollow cylindrical shape and is disposed on the side surface 3c of the rack 3B so as to extend in the vertical direction. The horizontal cross-sectional shape of the cylindrical body 26 is a substantially semicircular shape.

More specifically, the cylindrical body 26 includes a flat portion 26a that is linear in a horizontal cross-sectional shape, and a semicircular portion 26b that is connected to both ends of the flat portion 26a and has an arc shape. A plate-like support plate 28 extending in the vertical direction is fixed to the outer surface of the flat portion 26a, and the support plate 28 is attached to the side surface 3c of the rack 3B via the fixed plate 27. Is integrally fixed to the side surface 3c. Thereby, the semicircular portion 26b is arranged so as to protrude toward the rack 3A, and the top portion of the semicircular portion 26b comes into close contact with the side surface 3c of the rack 3A.
In place of the support plate 28, for example, grooves that can directly fix the fixing plate 27 are provided at both ends of the outer surface of the flat portion 26a, whereby the cylindrical body 26 is attached to the side surface 3c of the rack 3B by the fixing plate 27. It may be a configured.

  In the shielding structure 20 having such a configuration, the top of the cylindrical body 26 is in close contact with the side surface 3c of the rack 3A, so that the gap W formed between the racks 3A and 3B can be closed with a high degree of sealing. In addition, when the racks 3A and 3B vibrate and swing during an earthquake, the hollow cylindrical body 26 easily expands and contracts in the opposite direction of the side surface 3c, while ensuring the closed state of the gap W, The racks 3A and 3B can avoid interference and prevent the racks 3A and 3B from being deformed or damaged.

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 to this. For example, as shown in FIG. 9, when there is a structure 15 such as a pillar between the racks 3 and 3 of the rack group 9, the space between the side surface 3 c of the rack 3 and the side surface 15 a of the structure 15 facing each other. A configuration may be employed in which a gap W is formed in the gap and a shielding structure 20 is provided to close the gap.

  That is, the structure 15 such as a column is different from the rack 3 in the behavior 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.

  For example, as shown in FIG. 10, a rack type air conditioner 16 is provided between racks 3 and 3 of the rack group 9, and a side surface 16 a of the rack type air conditioner 16 and a side surface 3 c of the rack 3 that face each other. A configuration in which a gap W is formed therebetween and a shielding structure 20 is provided to close the gap may be employed.

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

  Furthermore, in the first to third embodiments, various functions may be added to the shielding structure 20 as shown in FIG. That is, in the shielding structure shown in FIG. 12, a temperature sensor 42 for detecting the temperature in the passage 4 is provided on the front surface, and a multipoint sensor that extends vertically and can detect temperature, humidity, and pressure at each height position. 46 etc. may be provided.

  For example, as shown in FIG. 13, when there is an overhead 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 overhead rack 17 and the rack 3 The gap W between the side surface 3 c and the gap W between the racks 3 and 3 formed above the elevated rack 17 may be closed using the shielding structure 20. In this case, the shielding structure 20 is installed separately into a plurality of parts according to the size of each gap W. Also by this, the cooling efficiency can be improved as described above. Further in this case, as shown in FIG. 14, various devices such as a multipoint sensor 46 capable of detecting temperature, humidity, and pressure may be provided in the shielding structure 20.
