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, 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 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 a gap between equipment housing racks, prevent damage due to the behavior of equipment housing racks and structures during an earthquake, and It is an object of the present invention to provide an inter-rack shielding structure capable of automatically returning to close the gap again at the end, and a computer room air conditioning system including the inter-rack shielding structure.

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, A rotating plate that extends in the vertical direction of the rotating plate and has a base end rotatably attached to one of the side surfaces, and the rotating plate rotates in a direction in which the rotating plate closes the gap. An urging member for urging the movement, and the rotating plate is substantially L-shaped in a plan view, and a tip portion of the rotating plate abuts the other side surface in the vertical direction. It is made possible .

  According to the inter-rack shielding structure having such a feature, the gap formed between the side surfaces of adjacent equipment storage racks or between the side surfaces of the equipment storage rack and the structure is rotated by a biasing member. The moving plate is blocked. 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, when the width of the gap changes due to vibration or swinging of the equipment rack or structure when an earthquake occurs, the rotating plate rotates against the biasing member according to the size of the width. Will move. That is, since the rotating plate is displaced 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 storage rack, and the structure from being deformed or damaged, and it is possible to maintain the cooling efficiency. Furthermore, when the earthquake is settled, the rotating plate can close the gap again by the urging force of the urging member, so that the automatic return can be achieved.
Furthermore, the gap formed between the pair of side surfaces can be reliably closed vertically by the tip of the rotating plate having a substantially L shape in plan view coming into contact with the other side surface by the biasing member. Can do.

Further, in the inter-rack shielding structure according to another aspect of the present invention, a plurality of air is provided on both sides of a passage having an internal space below the floor, and air is supplied from the front and heated from the top or the back. A rack for housing equipment 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, on the floor of the passage And the cooling air cools the equipment housed in the equipment housing rack, and then flows through the space above the equipment housing rack and is again sucked into the air conditioner. In an air conditioning system, an inter-rack shielding structure that closes a gap formed between adjacent side surfaces of adjacent equipment storage racks or between opposing side surfaces of the equipment storage rack and a structure. A rotating plate extending in the vertical direction of the gap and having a base end rotatably attached to one of the side surfaces, and a direction in which the rotating plate closes the gap, A urging member that urges the rotation of the rotating plate; and a fixed plate that protrudes from the other side surface toward the one side surface and extends in the vertical direction. Is capable of contacting the fixing plate in the vertical direction .

  The rotating plate abuts the fixed plate in the vertical direction according to the urging force of the urging member, so that the gap formed between the pair of side surfaces can be reliably closed. In addition, when an equipment rack or structure vibrates or swings due to an earthquake or the like, the rotating plate and the fixed plate exert a load on each other because the rotating plate rotates against the bias. Can prevent damage caused by. Furthermore, even when the equipment-accommodating rack or structure is tilted in the direction facing each other, the relative movement of the rotating plate and the fixed plate in this facing direction is allowed, so that the above damage is further reduced. It can be surely prevented.

  The inter-rack shielding structure preferably includes an elastic member disposed at at least one of the abutting portions of the rotating plate and the fixed plate.

  As a result, the rotating plate and the fixed plate are brought into close contact with each other via the elastic member, so that the passage is more reliably sealed and the cooling efficiency can be kept high. In addition, when the equipment housing rack or structure vibrates or swings, it is possible to more reliably prevent damage caused by the load applied to the rotating plate and the fixed plate.

  Further, in this inter-rack shielding structure, the portion that contacts the other side surface of the tip portion with respect to the axis extending in the opposing direction of the side surface passing through the base end portion is more than the axis line in plan view. It is preferable to be located on the side of the passage or on the opposite side of the passage.

  As a result, when the equipment-accommodating rack or structure vibrates or swings in the opposite direction of the side surface due to an earthquake, it is easy to give a moment in the rotational direction to the rotational plate. It can be rotated more smoothly. Therefore, the damage can be prevented more reliably.

  Further, the inter-rack shielding structure preferably includes an elastic member disposed at at least one of the portions where the tip portion of the rotating plate and the other side surface abut each other.

  As a result, the distal end portion of the rotating plate and the other side surface are in close contact with each other via the elastic member, so that the passage can be more reliably sealed. Further, it is possible to more reliably prevent damage caused by the load applied to the front end portion and the other side surface when the equipment housing rack or structure vibrates or swings.

  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 inter-rack shielding structure and the computer room air conditioning system of the present invention, the urging member urges the rotation of the rotating plate, whereby the gap between the equipment accommodating racks or the equipment accommodating rack and the structure are Can be reliably closed. Further, even when the equipment housing rack vibrates and swings due to an earthquake, the rotating plate rotates following the equipment housing rack or structure, so that the shielding structure, equipment housing rack, and structure Can be prevented from being damaged. Further, at the end of the earthquake, the rotating plate can be returned to the initial position by the urging force, and automatic return can be achieved. Therefore, it is possible to avoid a reduction in operating rate.

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 as shown in FIGS. 4 and 5, a rotating plate 21 and a spring hinge (biasing member). ) 22, sponge rubber (elastic member) 23, and a fixing plate 24.

  The rotating plate 21 is a rectangular plate-like member extending over the entire vertical direction of the gap W, and the base end portion 21a on one end side in the horizontal direction is connected to the side surface 3c (one side surface 3c) of the rack 3B via a spring hinge 22. ). Thereby, the rotation plate 21 can be rotated around the vertical axis O along the base end portion 21a. Further, the dimension from the base end portion 21a to the distal end portion 21b on the other end side in the horizontal direction of the rotating plate 21 is set to a size larger than, for example, one half of the width of the gap W.

  The spring hinge 22 is a member for fixing the rotating plate 21 to one side surface 3c so as to be rotatable around the vertical axis O. The spring hinge 22 is fixed to one side surface, and a fixed side plate 22a is connected to the fixed side plate 22a so as to be rotatable about a vertical axis O and is fixed to the rotary plate 21. Side plate 22b. Further, a biasing member such as a spring that biases the rotating side plate 22b toward the fixed side plate 22a between the fixed side plate 22a and the rotating side plate 22b of the spring hinge 22. (Not shown) is provided. Thereby, the rotation plate 21 is urged to rotate from the side of the passage 4 in the gap W toward the opposite side.

  The sponge rubber 23 is a member having cushioning properties, and is fixed over the entire region in the vertical direction of the surface facing the opposite side of the passage 4 at the tip 21b of the rotating plate 21. The rotating plate 21 contacts the fixed plate 24 through the sponge rubber 23.

  The fixed plate 24 is a plate-like member that extends over the entire vertical direction of the gap W and has an L-shape in a horizontal section view. The fixing plate 24 is attached to the side surface 3c (the other side surface 3c) of the rack 3A via, for example, a double-sided tape or a screw, and protrudes from the mounting portion 24a toward the side surface 3c of the rack 3B. And a projecting portion 24b having a rectangular plate shape. The fixed plate 24 is disposed so as to face the rotating plate 21 with a gap W therebetween. The protruding amount of the protruding portion 24b from the side surface 3c of the rack 3A toward the rack 3B is, for example, the width of the gap W. The dimension is set to be larger than one half of the above.

  In the shielding structure 20 having such a configuration, the rotating plate 21 is urged by the spring hinge 22 so that the tip 21b of the rotating plate 21 is fixed over the entire vertical direction of the gap W. It abuts against the 24 protruding portions 24b via the sponge rubber 23. As a result, the gap W is closed by the rotating plate 21 and the fixed plate 24. 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 3 </ b> A and 3 </ b> B vibrate and swing when the earthquake occurs and the width of the gap W changes, the rotating plate 21 rotates against the bias of the spring hinge 22. As a result, the rotating plate 21 is displaced following the behavior of the racks 3A and 3B, so that the rotating plate 21 and the fixed plate 24 do not exert loads on each other, and the shielding structure 20 and the rack 3A, It can also be avoided that 3B exerts 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.

  Furthermore, especially when the racks 3A and 3B are tilted in a direction facing each other, the rotating plate 21 and the fixed plate 24 are relatively moved in the facing direction. That is, since the relative movement between the rotating plate 21 and the fixed plate 24 in the direction is allowed, the deformation and breakage can be prevented more reliably.

Further, when the earthquake is stopped, the rotating plate 21 automatically returns to the initial state, that is, the state in which the rotating plate 21 is in contact with the fixed plate 24 via the sponge rubber 23 by the urging of the spring hinge 22. Thus, even when the rotating plate 21 rotates and the closed state of the gap W is released, the gap W can be automatically closed again, so that the closed state is automatically restored. It becomes possible. Therefore, for example, there is no need to perform an operation such as returning the rotating plate 21 displaced by the earthquake to the initial position, so that it is not necessary to stop the operation of the device, and a reduction in operating rate can be avoided.
Further, even when the racks 3A and 3B are tilted away from each other, there is almost no displacement in the lower part of the racks 3A and 3B as shown in FIG. There is no situation in which the gap 4 is completely rotated in the opposite direction of the passage 4 and the gap W cannot be closed thereafter.

  Furthermore, since the rotation plate 21 and the fixed plate 24 are in close contact with each other through the sponge rubber 23, the sealing performance of the passage 4 can be made more reliable and the cooling efficiency can be maintained higher. Furthermore, when the racks 3A and 3B vibrate and swing, the rotation plate 21 and the fixed plate 24 can be more reliably prevented from being damaged by applying a load to each other.

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 FIGS. 6 and 7, the shielding structure 20 of the second embodiment includes an L-shaped rotation plate (rotation plate) 31, a spring hinge (biasing member) 32, and a protective cap (elastic member). 33.

  The L-shaped rotating plate 31 is a plate-like member that extends over the entire vertical direction of the gap W, and has a structure that is bent so as to form a substantially L shape in plan view. In the L-shaped rotation plate 31, a portion on the base end portion 31a side which is fixed to the side surface 3c (one side surface 3c) of the rack 3B is a first plate portion 31c, and the first plate portion 31c. The second plate portion 31d is a portion on the distal end portion 31b side which is continuous at a predetermined angle (about 90 ° in the present embodiment). That is, the first plate portion 31c and the second plate portion 31d are connected so as to be substantially perpendicular in a plan view, and the corner portion 31e serving as a boundary between the first plate portion 31c and the second plate portion 31d is It arrange | positions so that it may protrude toward the channel | path 4 side. A closing plate 34 having a substantially triangular shape is provided at the upper end of the L-shaped rotating plate 31.

  The spring hinge 32 is a member for fixing the base end portion 31a of the L-shaped rotation plate 31 to be rotatable about the vertical axis O with respect to the one side surface 3c. The spring hinge 32 is connected to a fixed side plate 32a fixed to one side surface, and is connected to the fixed side plate 32a so as to be rotatable about a vertical axis O, and the first of the L-shaped rotating plate 31 is connected. And a rotation side plate 32b fixed to the plate portion 31c. Further, a biasing member such as a spring that biases the fixed side plate 32a between the fixed side plate 32a and the rotary side plate 32b in the direction in which the fixed side plate 32a approaches the fixed side plate 32b. (Not shown) is provided. Thus, the L-shaped rotation plate 31 is urged to rotate from the opposite side of the passage 4 in the gap W toward the passage 4 side.

  The protective cap 33 is a member having elasticity, and is provided so as to protect the distal end portion 31b of the L-shaped rotation plate 31 over the entire vertical direction. As a result, the L-shaped rotating plate 31 comes into contact with the side surface 3c (the other side surface 3c) of the rack 3A via the protective cap 33.

  Here, in the present embodiment, the distance d between the base end portion 31 a and the tip end portion 31 b of the L-shaped rotation plate 31 is set to be larger than the width of the gap W. Thereby, it arrange | positions so that the direction along the distance d may incline with respect to the opposing direction of the side surface 3c. Further, the other side surface of the distal end portion 31b of the L-shaped rotation plate 31 is based on the reference axis P passing through the base end portion 31a of the L-shaped rotation plate 31 and extending in the opposing direction of the side surface 3c. The part that abuts on 3c is located on the opposite side of the passage 4 from the reference axis P in plan view. Instead of this, for example, as shown in FIG. 8, the portion that contacts the other side surface 3 c of the tip portion 31 b of the L-shaped rotation plate 31 is located closer to the passage 4 than the reference axis P in plan view. You may do it. That is, the tip 31b of the L-shaped rotation plate 31 is in contact with the side surface 3c at a position offset from the reference axis P.

  In the shielding structure 20 having such a configuration, the L-shaped rotation plate 31 is urged to rotate by the spring hinge 32, so that the distal end portion 31 b of the L-shaped rotation plate 31 is located in the gap W. It abuts against the other side surface 3c over the entire vertical direction. As a result, it is possible to prevent the gap W from being closed by the L-shaped rotating plate 31, so that the hot air discharged from the rack 3 is recirculated into the passage and sucked into the rack 3 again. It can be reliably sent to the harmony device 6, and the cooling efficiency of the equipment can be sufficiently secured.

Further, when the racks 3A and 3B vibrate and swing when the earthquake occurs and the width of the gap W changes, the L-shaped rotating plate 31 rotates against the bias of the spring hinge 32. become. Thereby, since the L-shaped rotation plate 21 is displaced following the behavior of the racks 3A and 3B, the deformation and breakage of the shielding structure 20 and the racks 3A and 3B can be prevented and the cooling efficiency can be reduced as in the first embodiment. Can be maintained.
Further, particularly when the racks 3A and 3B are tilted in the direction facing each other, the L-shaped rotating plate 31 rotates against the bias of the spring hinge 32, so that the L-shaped rotating plate. The tip 31b of 31 can be slid in the offset direction, and the L-shaped rotating plate 21 can be prevented from being damaged. At this time, the racks 3A and 3B are allowed to approach each other up to the distance between the base end portion 31a and the corner portion 31e of the L-shaped rotating plate 21.

Even when the racks 3A and 3B are tilted away from each other, as shown in FIG. 2, there is almost no displacement at the lower part of the racks 3A and 3B. Thus, the gap W cannot be closed thereafter.
Further, when the earthquake stops, the L-shaped rotating plate 31 automatically returns to the initial state by the urging of the spring hinge 32, so that automatic recovery can be achieved.

  In addition, since the tip 31b of the L-shaped rotation plate 31 is in contact with the side surface 3c at a position offset from the reference axis P, the rack 3 vibrates and swings in the direction opposite to the side surface 3c due to an earthquake. In this case, it becomes easier to apply a moment in the rotation direction of the L-shaped rotation plate 31, and the L-shaped rotation plate 31 can be rotated more smoothly. Thereby, the said deformation | transformation and damage can be prevented more reliably. In addition, when the part which contact | abuts the other side surface 3c of the front-end | tip part 31b of the L-shaped rotation board 31 is located in the other side of the channel | path 4 rather than the reference | standard axis P in planar view, it is L-shaped rotation. The moving plate 31 is easily rotated toward the opposite side of the passage 4. On the other hand, when the portion that contacts the other side surface 3c of the tip portion 31b of the L-shaped rotation plate 31 is located on the side of the passage 4 with respect to the reference axis P in plan view, the L-shaped rotation plate It becomes easy to rotate 31 toward the channel | path 4 side.

  Furthermore, since the front end portion 31b of the L-shaped rotating plate 31 and the other side surface 3c are in close contact with each other through the protective cap 33, the sealing performance of the passage 4 can be further ensured. Further, when the rack 3 vibrates and swings, it is possible to more reliably prevent damage due to the tip 31b and the other side surface 3c exerting loads on each other.

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.

  Further, various functions may be added to the shielding structure 20 as shown in FIG. That is, the shielding structure shown in FIG. 12 has a temperature sensor 42 for detecting the temperature in the passage 4 on the front surface, and a plurality of points that extend vertically to detect temperature, humidity, and pressure at each height position. Sensor 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.
