Description

  The present invention relates to a computer room air conditioning system.

Conventionally, various air conditioning systems for adjusting the air flow and temperature in a certain space have been proposed.
Among these air conditioning systems, air conditioning for computer rooms that adjusts the flow and temperature of air around the equipment in computer rooms where OA equipment and communication devices, etc. that tend to be highly integrated and heat-generating are installed. The system is known.
As an air conditioning system for a computer room, a plurality of equipment storage racks arranged opposite to each other with a predetermined space (passage) in between, and an air conditioner disposed on the side of the equipment storage rack and facing the predetermined space There is something with.

Under such a configuration, when the air conditioner discharges the cooling air downward, the cooling air is sent to a predetermined space and sucked into the equipment housing rack. Then, the cooling air is warmed by cooling the equipment housed in the equipment housing rack, and then blown out from the equipment housing rack. Then, the warmed and blown air flows through the upper space of the computer room, is sucked into the air conditioner, and is cooled and discharged again.
Thereby, the flow and temperature of the air in the computer room are controlled.

However, a part of the air that has been warmed and blown out from the equipment housing rack may be directly returned to the predetermined space from the upper space without being sent to the air conditioner. In that case, the air recirculated to the predetermined space is sucked into the equipment housing rack again in a warmed state, thereby reducing the cooling efficiency of the equipment.
Therefore, it is conceivable to prevent the flow of air from the upper space to the predetermined space by bridging a shielding plate (shielding body) over the upper surfaces of the equipment housing racks facing each other across the passage (for example, Patent Documents). 1).

Japanese Patent No. 3833515

  By the way, when a shielding plate is installed as in Patent Document 1, a bolt or the like is attached to the device housing rack so that the shielding plate does not easily fall off from the upper surface of the device housing rack. The racks for accommodating devices are fixed so that they cannot move relative to each other.

  However, when the equipment housing racks are fixed to each other using the shielding plates in this way, when these equipment housing racks vibrate or swing due to, for example, an earthquake, an excessive load is applied to the equipment housing racks or the shielding plates. There is a problem that it takes. That is, these equipment housing racks swing and swing toward the passage side or the opposite side of the passage, or tilt in a direction along the passage, and are greatly deformed by applying stress to each other via the shielding plate. It may be damaged or the shielding plate may be deformed and damaged.

  The present invention has been made in view of such circumstances, and efficiently cools a device housed in a device housing rack using a shield, and the device housing rack vibrates or shakes due to an earthquake or the like.

Therefore, the cooling efficiency of the equipment is sufficiently ensured. In addition, since the equipment housing racks on both sides of the passage sandwiching the passage are connected to each other so that they can move relative to each other, even if the equipment housing rack is displaced by vibration or swinging due to an earthquake or the like, it does not exert stress on each other. These displacements are allowed. Therefore, it is possible to prevent the equipment housing rack and the shield from being damaged.
Also, when the equipment housing rack vibrates or swings due to an earthquake or the like, if the equipment housing racks facing each other across the passage move relatively in the direction along the passage, the shielding material rotates in accordance with the relative movement. Thus, the device housing racks are prevented from exerting stress on each other.

Further, by using the elastic member, the shielding material since it is opened and closed by rotating around the elastic member, for example, by the open state of the shielding material, such as during maintenance, the above the shielding material Maintenance work etc. can be done easily.

When the equipment storage rack vibrates or swings due to an earthquake or the like, if the equipment storage racks facing each other across the passage move relatively in the direction along the passage, this The shielding member is rotated in accordance with the relative movement, so that the device housing racks are prevented from exerting stress on each other. Therefore, it is possible to prevent the equipment housing rack and the shield from being damaged.

In the computer room air conditioning system according to the present invention, a plurality of the shielding materials may be provided along the passage.
According to the computer room air conditioning system of the present invention, since a plurality of shielding members are provided along the passage, for example, during maintenance, only the necessary shielding material is opened and the shielding material is opened. Maintenance work and the like above can be performed more easily. That is, the operator only needs to open and close only the shielding material necessary for the work, and the work load is greatly reduced.

Further, in the computer room air conditioning system according to the present invention, a plurality of the equipment accommodation racks are arranged along the passage, and the heights thereof are different from each other. On the upper surface of the lower one, a plate-like partition member is erected so as to face the passage, and the partition members are arranged so that the heights of the front surfaces facing the passages of the equipment housing racks are mutually equal. It is good also as setting same .

It is a side view which shows schematic structure of a body.

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. A passage 4 extending in the longitudinal direction is formed in the double floor 2. The double floor 2 is formed with a rectangular long hole 8 penetrating in the thickness direction. A rectangular plate-shaped perforated panel 7 covering the long hole 8 is fitted over the entire circumference of the edge of the long hole 8. The perforated panel 7 has a plurality of holes penetrating in the thickness direction. Thereby, the internal space 5 under the floor and the space of the passage 4 communicate with each other through the plurality of holes.

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 accommodating rack) 3 and an air conditioner 6 that are arranged opposite to each other across 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 lateral direction of the passage 4 (hereinafter sometimes referred to as “width direction”). The rack 3 supplies air in the space of the passage 4 from an air supply port (not shown) formed on the opposing surfaces (front surface 3b) facing each other, and the supplied air is supplied from the upper surface 3a or the rear outlet. It blows out upward or backward.

Here, the allowable displacement amount of the rack 3 when the rack 3 vibrates or swings due to an earthquake or the like will be described.
As shown in FIG. 2, the rack 3 is erected on the double floor 2 with its longitudinal direction arranged in the vertical direction. For example, the outer dimensions are 600 mm to 700 mm in width × 900 mm to 1200 mm in depth × height. It is formed to about 2000 mm. In this way, the rack 3 is formed so as to extend in the vertical direction, and a relatively high and relatively heavy communication device is accommodated. The bottom surface portion is shaken with the vibration of the double floor 2, and the large stress f acts on the top surface portion and is shaken.

  In FIG. 2, when d is a distance (hereinafter referred to as “displacement amount”) in which the rack 3 tilts horizontally when the stress f from the side acts on the upper surface portion of the rack 3, the rack 3 tilts. As shown in FIG. 3, as the stress f gradually increases from 0, the displacement amount d gradually increases so as to be substantially proportional to the stress f. When a certain displacement amount da is exceeded, the displacement amount d gradually increases even if the stress f does not increase any more, and the rack 3 is damaged. That is, the displacement amount da is the maximum allowable displacement amount of the rack 3, and this displacement amount da is, for example, several centimeters.

  Moreover, as shown in FIG. 1, the air conditioning apparatus 6 is formed in the box shape. The air conditioner 6 is arranged on the side of the rack 3 and on one end (right side in FIG. 1) in the longitudinal direction of the passage 4. The air conditioner 6 blows out cooling air from the outlet on the lower surface 6b, sucks the air flowing in the upper space of the computer room 101 from the suction port on the upper surface 6a, cools it, and then blows again. It comes to blow out from.

Moreover, the code | symbol 13 shown in FIG. 1 is a wall body (both-end shielding part) which is arrange | positioned at the one end part of the longitudinal direction of the channel | path 4, and divides the space of this channel | path 4 and external space. 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 being configured in this way, the wall 13 blocks the space on the side of the passage 4 and the space on the side of the air conditioner 6, and the cold air blown out from the perforated panel 7 is directly drawn into the air inlet 6 a of the air conditioner 6. Inhalation (prevention of short circuit phenomenon). Therefore, a sufficient amount of cold air can be supplied to the internal space 5, the cold air can be sufficiently sent to the rack 3 away from the air conditioner 6, and the cooling efficiency can be improved.
Further, by providing the door 13a, an operator can enter and exit the passage 4 through the door 13a.

Further, a wall body (both-end shielding portion) 14 having an openable / closable door 14a is also provided at the other end (left side in FIG. 1) of the passage 4 in the longitudinal direction. As a result, the exhaust heat exhausted from the rack 3 is prevented 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.
As described above, the walls 13 and 14 are disposed at both ends in the longitudinal direction of the passage 4 as a pair of both-end shielding portions that shield the both ends.

A shield 11 is bridged between the upper surfaces 3a of the racks 3 arranged on both sides with the passage 4 in between.
As shown in FIG. 4, the shield 11 includes a hinge member 111 provided on the upper surface 3 a of the rack 3 arranged on one side (left side in FIG. 4) sandwiching the passage 4, and the other side sandwiching the passage 4 ( A roller (supporting member) 112 provided on the upper surface 3a of the rack 3 arranged on the right side in FIG. 4 and a shielding plate (shielding) that is rotatably supported by the hinge member 111 and can contact the roller 112. Material) 113.

  The hinge member 111 has a substantially rectangular flat plate shape or a substantially flat bar shape, the main body portion extends along the longitudinal direction of the passage 4, and the pin support portions 111 a at both ends of the main body portion are orthogonal to the main body portion. Each is folded upward. These pin support portions 111a are respectively formed with pin holes 111b penetrating in the horizontal direction. Further, the outer dimension in the extending direction of the hinge member 111 is set to be substantially the same as the outer dimension in the extending direction of the plurality of racks 3 arranged on one side of the passage 4.

  In addition, a plurality of holes 111c are formed in the main body portion of the hinge member 111 at intervals in the extending direction. Bolts 114 are inserted into the holes 111c and the top surface 3a of each rack 3 is formed. It is screwed. A hinge member 111 is fixed to the upper surface 3 a of each rack 3 by these bolts 114, and a plurality of racks 3 arranged on one side of the passage 4 are integrally connected via the hinge member 111.

  In addition, the roller 112 has a rod shape with a substantially bowl-shaped cross section, and extends along the longitudinal direction of the passage 4. The outer dimension in the extending direction of the roller 112 is set to be substantially the same as the outer dimension in the extending direction of the plurality of racks 3 arranged on the other side of the passage 4. The roller 112 has a plurality of holes 112a that are spaced apart in the extending direction. Bolts 115 are inserted into the holes 112a and screwed to the upper surface 3a of each rack 3, respectively. Yes. The rollers 112 are fixed to the upper surface 3 a of each rack 3 by these bolts 115, and a plurality of racks 3 arranged on the other side of the passage 4 are integrally connected via the rollers 112.

  The shielding plate 113 has a substantially rectangular flat plate shape, and extends in the longitudinal direction of the passage 4 so as to cover the upper portion of the passage 4. At one end of the shielding plate 113, substantially round bar-shaped pins 113a are provided extending in the longitudinal direction of the passage 4, respectively, and these pins 113a are pin holes 111b of the pin support portion 111a of the hinge member 111. It is inserted and supported in a rotatable manner. Further, the other end of the shielding plate 113 sufficiently protrudes toward the other side from the position where the roller 112 is disposed, and the lower surface of the shielding plate 113 and the upper end of the roller 112 can be brought into contact with each other. Yes. Specifically, the length L of the shielding plate 113 protruding from the upper end of the roller 112 to the other side is set to be twice or more the allowable displacement amount da of the rack 3 described above. Further, the lower surface of the shielding plate 113 and the upper end of the roller 112 are in contact with each other so as to slide relative to each other.

  With such a configuration, the shielding plate 113 can rotate about the hinge member 111 and can open and close the upper portion of the passage 4. When the lower surface of the shielding plate 113 is brought into contact with the roller 112 to be in a closed state, the opposing racks 3 are sandwiched by the shielding member 11 with the passage 4 interposed therebetween, and the passage 4 and the rack are connected to each other. 3 is partitioned.

Next, the cooling effect | action of the computer room air conditioning system 100 in this reference example is demonstrated.
In the computer room 101 shown in FIG. 1, when the communication apparatus etc. which were accommodated in the rack 3 operate | move, those each apparatus will be heated. Therefore, it is necessary to cool each operating device.
Therefore, cooling air is blown out into the internal space 5 from the outlet of the lower surface 6 b of the air conditioner 6. This cooling air is blown upward (space of the passage 4) from the plurality of holes of the perforated panel 7 through the internal space 5. Then, the cooling air sent to the space of the passage 4 is supplied from the air supply port of the front surface 3b of the rack 3, and cools each device by heat exchange action. Thereby, the supplied air is warmed and becomes hot air. The hot air is blown upward from the upper surface 3a of the rack 3 or the air outlet on the rear surface. Further, the hot air blown out flows in the upper space of the computer room 101 to one end side along the longitudinal direction of the passage 4 and is sucked and cooled from the suction port of the upper surface 6a of the air conditioner 6. Then, it blows out again from the blower outlet of the lower surface 6b.
Thereby, the flow and temperature of the air in the computer room 101 are controlled, and the favorable operation state of each apparatus is maintained.

By the way, conventionally, the hot air blown from the upper surface 3 a or the rear surface of the rack 3 is returned to the space of the passage 4 and supplied from the front surface 3 b of the rack 3 before being supplied to the air conditioner 6. There was a case.
However, in this reference example , the shield 11 is disposed between the upper surfaces 3a of the racks 3 facing each other with the passage 4 therebetween, and the upper space of the rack 3 and the space of the passage 4 are partitioned. Therefore, the hot air on the upper surface 3 a of the rack 3 is restricted from flowing into the space of the passage 4. That is, the space of the passage 4 is always filled with the cooling air from the floor of the double floor 2 to the shield 11.

Further, conventionally, the cooling air in the passage 4 may be directly sucked into the air conditioner 6 without being supplied to the rack 3.
However, in this reference example , the wall body 13 is disposed between the floor of the double floor 2 and the shield 11 so as to close one end portion in the longitudinal direction of the passage 4, and the space of the passage 4. And the installation space of the air conditioner 6 are partitioned, so that the cooling air in the passage 4 is restricted from flowing into the installation space of the air conditioner 6.
In addition, a wall body 14 is disposed between the floor of the double floor 2 and the shield 11 so as to close the other end portion in the longitudinal direction of the passage 4. Since the external space on the other end side is partitioned, the hot air blown out from the rack 3 is prevented from entering around the other end side of the passage 4 and entering the passage 4. Therefore, even the equipment accommodated in the rack 3 arranged at the other end in the longitudinal direction of the passage 4 can be sufficiently cooled.

As described above, according to the computer room air conditioning system 100 of the present reference example , the shielding plate 113 of the shielding body 11 is bridged between the upper surfaces 3a of the racks 3 arranged on both sides of the passage 4. Since the shield 4 partitions the passage 4 and the space above the rack 3, the air blown out from the rack 3 is prevented from flowing back into the passage 4 and being sucked into the rack 3. In addition, the cooling efficiency of the equipment that is reliably sent to the air conditioner 6 and accommodated in the rack 3 is ensured.

  In addition, since the shielding plates 113 of the shielding body 11 connect the racks 3 on both sides of the passage 4 so that they can move relative to each other, even if these racks 3 are displaced by vibration or swinging due to an earthquake or the like, the stress f These displacements are allowed without affecting. Therefore, the rack 3 and the shield 11 are prevented from being damaged. That is, for example, the racks 3 vibrate or swing due to an earthquake or the like as compared with the case where the racks 3 arranged on both sides of the passage 4 are fixedly connected to each other so as not to move relative to each other using the shield 11. It is possible to reliably prevent the stress f from being applied to each other and greatly deformed and damaged beyond the allowable displacement amount da or the shield 11 is deformed and damaged.

  In addition, the shield 11 includes a hinge member 111 on one side across the passage 4, a roller 112 on the other side, and a shield plate 113 that is rotatably supported by the hinge member 111 and can contact the roller 112. Since the shielding plate 113 is pivotable about the hinge member 111 and can be opened and closed, for example, when the shielding plate 113 is opened during maintenance, the shielding plate 113 can be opened above the shielding plate 113. Maintenance work etc. can be done easily.

  In addition, a plurality of racks 3 are arranged along the passage 4 on one side and the other side of the passage 4, respectively, and the racks 3 on one side are connected together using a hinge member 111, and the other side Since the racks 3 are integrally connected using the rollers 112, the racks on one side and the racks on the other side vibrate or swing in the direction along the passage 4 due to an earthquake or the like. Is suppressed. Therefore, it is possible to prevent the racks adjacent to each other along the passage 4 from oscillating or swinging to collide with each other or to be damaged by applying stress f.

  Further, the other end of the shielding plate 113 of the shielding body 11 is formed so as to sufficiently protrude from the roller 112 to the other side, and the length L protruding from the roller 112 to the other side is the allowable displacement amount of the rack 3. Since it is set to be twice or more of da, the racks facing each other across the passage 4 vibrate or swing due to an earthquake or the like, and are tilted away from each other in the short direction of the passage 4, for example, allowable displacement Even in the case of displacement by the amount da, the upper end of the roller 112 indicated by a two-dot chain line in FIG. 4 is not arranged on the other side of the end portion of the shielding plate 113. Therefore, the shield plate 113 is prevented from falling off from the upper end of the roller 112 and being damaged.

A plurality of shielding plates (shielding materials) 123 are provided. Further, these shielding plates 123 are arranged along the longitudinal direction of the passage 4 and are bridged between the upper surfaces 3 a of the racks 3 arranged on both sides of the passage 4.

  The hinge member 121 has a substantially rectangular flat plate shape or a substantially flat bar shape, and a main body portion extends along the longitudinal direction of the passage 4. In addition, a plurality of pin support portions 121a are erected so as to be orthogonal to the main body portion, and these pin support portions 121a are arranged at substantially equal intervals in the extending direction of the main body portion. These pin support portions 121a are respectively formed with pin holes 121b penetrating in the horizontal direction.

The shielding plate 123 has a substantially rectangular flat plate shape and is arranged in the longitudinal direction of the passage 4 so as to cover the upper portion of the passage 4.

The pin hole 121b of the pin support part 121a is rotatably inserted and supported.
With such a configuration, the shielding plate 123 can rotate around the hinge member 121 and can open and close the upper portion of the passage 4.

As described above, according to the computer room air conditioning system 100 of the present reference example , since a plurality of the shielding plates 123 of the shielding body 21 are provided along the passage 4, the necessary shielding is performed at the time of maintenance or the like. Maintenance work and the like above the shielding plate 123 can be performed more simply with only the plate 123 open. That is, the worker only needs to open and close only the shielding plate 123 necessary for the work, and the work load is greatly reduced.

The outer dimension in the extending direction of the runner 35 is set to be substantially the same as the outer dimension in the extending direction of the plurality of racks 33 arranged on one side of the passage 4. The runner 35 is provided with a plurality of holes (not shown) spaced in the extending direction. Bolts (not shown) are inserted into the holes, and each of the heights is high. The rack 33 is screwed to the upper surface 33a. With such a configuration, the plurality of racks 33 arranged on one side of the passage 4 are integrally connected via the runner 35.

  A bar-like roller (support member) 132 extending along the longitudinal direction of the passage 4 is provided on the upper surface 33a of the rack 33 arranged on the other side across the passage 4 (right side in FIG. 6). . The outer dimension in the extending direction of the roller 132 is set to be substantially the same as the outer dimension in the extending direction of the plurality of racks 33 arranged on the other side of the passage 4. The roller 132 has a plurality of holes (not shown) that are spaced apart in the extending direction, and bolts (not shown) are inserted into these holes and each of the heights is high. The rack 33 is screwed to the upper surface 33a. With such a configuration, the plurality of racks 33 arranged on the other side of the passage 4 are integrally connected via the rollers 132.

A shield 31 is bridged between the upper surfaces 33a of the racks 33 arranged on both sides of the passage 4.
The shield 31 includes a hinge member (not shown) provided on each upper surface 33a of the rack 33 at both ends in the longitudinal direction of the passage 4 among the racks 33 arranged on one side across the passage 4, the roller 132, And a shielding plate (shielding material) 133 that is rotatably supported by the hinge member and that can be brought into contact with the roller 132.

  The shielding plate 133 is supported at one end thereof by a substantially round bar-shaped shaft body 133a. The shaft body 133a extends along the longitudinal direction of the passage 4, and both ends in the extending direction are supported by the hinge member so as to be rotatable around the axis. Further, the other end of the shielding plate 133 protrudes sufficiently to the other side from the position where the roller 132 is disposed, and the lower surface of the shielding plate 133 and the upper end of the roller 132 can be brought into contact with each other. Yes. Further, the lower surface of the shielding plate 133 and the upper end of the roller 132 are slidable relative to each other while being in contact with each other.

With such a configuration, the shielding plate 133 can be rotated around the hinge member, and the upper portion of the passage 4 can be opened and closed. When the lower surface of the shielding plate 133 is brought into contact with the roller 132 to be closed, the opposing racks 33 with the shield 31 sandwiching the passage 4 are connected to each other so as to be relatively movable, and the passage 4 and the rack are connected. A space above 33 is defined.
As described in the second reference example , a plurality of shielding plates 133 are provided and arranged in the longitudinal direction of the passage 4 so that each shielding plate 133 can rotate about the shaft body 133a. It doesn't matter.

As described above, in the computer room air conditioning system 200 of the present reference example , the partition member 34 is arranged between the end of the upper surface 33a of the rack 33 having a low height on the side of the passage 4 and the shielding plate 133. Since the upper space of the rack 33 and the space of the passage 4 are partitioned, the hot air on the upper surface 33a of the rack 33 is restricted from flowing into the space of the passage 4. That is, since the space of the passage 4 is always filled with the cooling air from the floor of the double floor 2 to the shield 31, the cooling efficiency is ensured.

Further, according to the shielding body 31 of this reference example , the shielding plate 133 connects the racks 33 on both sides sandwiching the passage 4 so as to be relatively movable, so that these racks 33 vibrate or swing due to an earthquake or the like.

Next, a fourth embodiment of the present invention will be described.
FIG. 7 is a side view showing a schematic configuration of a shielding body of a computer room air conditioning system according to the fourth embodiment of the present invention, and FIG. 8 is a diagram of the computer room air conditioning system according to the fourth embodiment of the present invention. It is a top view which shows schematic structure of a shield. In addition, the same code | symbol is attached | subjected to the same member as the shielding bodies 11,21,31 of the above-mentioned 1st thru | or 3rd reference example , and the description is abbreviate | omitted.
This embodiment and the first to third reference examples have the same basic configuration, and different points will be mainly described here.

  As shown in FIGS. 7 and 8, the shield 41 of the fourth embodiment is provided on the upper surface 3 a of the rack 3 arranged on one side (left side in FIGS. 7 and 8) sandwiching the passage 4. The bar-shaped runner (first support member) 141 extending in the longitudinal direction of 4 and the upper surface 3a of the rack 3 arranged on the other side (right side in FIGS. 7 and 8) sandwiching the passage 4 are arranged in the longitudinal direction. And a rod-shaped roller (second support member) 142 extending in a straight line, and a plurality of substantially rectangular plate-shaped shielding plates (shielding materials) 143 spanning the runner 141 and the roller 142. Further, these shielding plates 143 are arranged along the longitudinal direction of the passage 4.

Further, a hole 143a penetrating in the vertical direction is formed at one end of each shielding plate 143.
In addition, on the upper surface of the runner 141, substantially round bar-shaped shaft portions 141a are provided at positions corresponding to the holes 143a of the respective shielding plates 143, and these shaft portions 141a extend in the vertical direction and are inserted into the holes 143a. . The outer diameter of the shaft portion 141a is set slightly smaller than the inner diameter of the hole 143a of the shielding plate 143, and the shielding plate 143 rotates around the shaft portion 141a with the shaft portion 141a inserted into the hole 143a. It is possible.

  Further, the other end portion of the shielding plate 143 sufficiently protrudes toward the other side from the position where the roller 142 is disposed, and the lower surface of the shielding plate 143 and the upper end of the roller 142 can be brought into contact with each other. Yes. Further, the lower surface of the shielding plate 143 and the upper end of the roller 142 are slidable relative to each other while being in contact with each other.

  In this way, the shields 41 connect the racks 3 facing each other with the passage 4 interposed therebetween so as to be relatively movable, and the passage 4 and the space above the rack 3 are partitioned.

  As described above, according to the shielding body 41 of the present embodiment, the shielding plate 143 can be rotated around the shaft portion 141a on the upper surface of the runner 141. When the racks 3 that face each other across the passage 4 move relative to each other along the longitudinal direction of the passage 4 when swinging, the shielding plate 143 rotates in accordance with the relative movement. Is prevented. Further, even when the racks 3 facing each other across the passage 4 are moved toward and away from each other, the shielding plate 143 is slidable on the upper surface of the roller 142 so that the racks 3 can be moved. Are prevented from stressing each other. Therefore, the rack 3 and the shield 41 are prevented from being damaged.

( Reference Example 5)
Next, a fifth reference example which is a premise of the fifth embodiment of the present invention will be described.
FIG. 9: is a side view which shows schematic structure of the shielding body of the air conditioning system for computer rooms which concerns on the 5th reference example used as the premise of the 5th Embodiment of this invention. In addition, the same code | symbol is attached | subjected to the same member as the shielding bodies 11, 21, 31, and 41 of the above-mentioned 1st thru | or 3rd reference example and 4th embodiment, The description is abbreviate | omitted.
Basic structure as the reference example and the first to third reference examples and the fourth embodiment are the same and will be described here mainly different points.

As shown in FIG. 9, the shield 51 of the fifth reference example is provided on the upper surface 3 a of the rack 3 arranged on one side (left side in FIG. 9) across the passage 4 and extends in the longitudinal direction of the passage 4. A substantially rod-like first hinge shaft (first hinge member) 151 and a substantially rod-like shape provided on the upper surface 3a of the rack 3 arranged on the other side (right side in FIG. 9) across the passage 4 and extending in the longitudinal direction. A second hinge shaft (second hinge member) 152 and a substantially rod-shaped third hinge shaft (third hinge member) disposed between the first hinge shaft 151 and the second hinge shaft 152 and extending in the longitudinal direction. 153.
The first hinge shaft 151 is fixed to the upper surface 3a of the rack 3, and the second hinge shaft 152 is detachable from the upper surface 3a.

  The shield 51 connects the first hinge shaft 151 and the third hinge shaft 153 and is supported by the first and third hinge shafts 151 and 153 so as to be rotatable. The first shielding member 154, the second hinge shaft 152 and the third hinge shaft 153 are connected to each other, and the second and third hinge shafts 152 and 153 are rotatably supported by the substantially rectangular plate-shaped second shielding plate. (Second shielding material) 155.

  With such a configuration, the first shielding plate 154 of the shield 51 can be rotated about the first hinge shaft 151, and the second shielding plate 155 can be rotated about the second hinge shaft 152, The first shielding plate 154 and the second shielding plate 155 are rotatable with respect to each other about the third hinge shaft 153.

As described above, according to the shielding body 51 of this reference example , the first shielding plate 154 can be rotated around the first hinge shaft 151, and the second shielding plate 155 is centered on the second hinge shaft 152. Since the first shielding plate 154 and the second shielding plate 155 can be rotated around the third hinge shaft 153, the rack 3 vibrates or swings due to an earthquake or the like. In addition, when the racks 3 facing each other across the passage 4 are moved closer to and away from each other and moved relative to each other, the first shielding plate 154 and the second shielding plate 155 rotate as described above. Are prevented from stressing each other. Therefore, the rack 3 and the shield 51 are prevented from being damaged.

  Further, since the second hinge shaft 152 can be attached to and detached from the upper surface 3a of the rack 3, the second hinge shaft 152 can be detached from the upper surface 3a during maintenance or the like, and the shield 51 can be opened. . Accordingly, maintenance work and the like above the shield 51 can be easily performed.

A plurality of the first and second shielding plates 154 and 155 may be provided and arranged along the passage 4. When the first shielding plate 154 can be attached to and detached from the first and third hinge shafts 151 and 153 and the second shielding plate 155 is attached to and detached from the second and third hinge shafts 152 and 153, maintenance can be performed. For example, maintenance work and the like above the first and second shielding plates 154 and 155 can be easily performed by opening only the necessary first and second shielding plates 154 and 155.
Furthermore, a plurality of first, second, and third hinge shafts 151, 152, and 153 may be provided so as to be divided in the extending direction corresponding to the first and second shielding plates 154 and 155. According to this configuration, the first and third hinge shafts 151 and 153 can be removed without removing the first and second shielding plates 154 and 155 from the first, second and third hinge shafts 151, 152 and 153. By turning to the center, each can be opened.

The present invention is not limited to the first to fifth embodiments described above, and various modifications can be made without departing from the spirit of the present invention.
For example, the shield is only required to connect the racks 3 (33) arranged with the passage 4 interposed therebetween so that the racks 3 (33) can be moved relative to each other, so that the short side of the passage 4 is connected to the upper surface 3a (33a) of the rack 3 (33). A track member such as a rail may be provided along the direction, the shield plate of the shield may be engaged with the track member, and the shield plate may be movable along the track member. With such a configuration, even if the racks 3 (33) approach and separate from each other and move relative to each other, excessive stress f is not applied to each other, and damage to the rack 3 (33) and the shield is prevented. The

Further, in the above-described reference example and embodiment, it has been described that the substantially rectangular plate-shaped shielding plates 113, 123, 133, and 143 and the first and second shielding plates 154 and 155 are used. It is not limited to the shape, and other shapes such as a sheet shape, a film shape, and a cloth shape may be used. The material of the shielding plates (first and second shielding plates) is not particularly limited, but the shielding plate (first and second shielding plates) is installed above the passage 4 by being formed of a transparent material such as glass or resin. It is more preferable because illuminance such as illumination can be sufficiently secured.

In the first to third reference examples and the fourth embodiment, the other ends of the shielding plates 113, 123, 133, and 143 are the rollers 112 of the upper surfaces 3 a and 33 a of the other racks 3 and 33. Although described as contacting the upper end of 132,142, it is not limited to this. In other words, the other end of the shielding plates 113, 123, 133, and 143 may be in direct contact with the upper surfaces 3a and 33a of the other racks 3 and 33. Moreover, it does not matter as abutting against other supporting members such as a sheet member or a protruding member other than the roller.

In the first and second reference examples , the main body portions of the hinge members 111 and 121 extend along the longitudinal direction of the passage 4, and the outer dimensions of the hinge members 111 and 121 in the extending direction are Although the outer dimensions in the extending direction of the plurality of racks 3 arranged on one side are set to be substantially the same, the present invention is not limited to this. Further, in the third reference example , the shaft body 133a extends along the longitudinal direction of the passage 4, and the upper surfaces 33a of the racks 33 at both ends among the plurality of racks 33 arranged on one side of the passage 4 are provided. The hinge member provided is supported at both ends thereof and is rotatable. However, the present invention is not limited to this.

  That is, the hinge members 111 and 121 and the shaft body 133a may be divided in the extending direction so as to correspond to the plurality of racks 3 and 33 arranged on one side of the passage 4, and a plurality of the hinge members 111 and 121 and the shaft body 133a may be provided. I do not care.

  In the fourth embodiment, instead of the shaft portion 141a, a spherical bearing member such as a ball joint may be provided on the upper surface 3a of the rack 3, and the spherical bearing member may be connected to the shielding plate 143. That is, the shielding plate 143 may be pivotally supported using a spherical bearing member. In this case, the freedom degree of the direction which opens and closes the shielding board 143 increases.

Then, in the first to fifth embodiment of the present invention, the aforementioned hinge members 111 and 121, the shaft 133a, the shaft portion 141a, first, in place of the second hinge shaft 151, a rack 3, 33 of the upper surface 3a, arranged elastically deformable elastic member 33a, the elastic member shielding plate 113,123,133,143, first, are connected to the second shield plate 154, 155. That is, by the elastic member is elastically deformed, the shielding plates 113,123,133,143, first, is configured so as to open and close the second shielding plate 154, 155. As a result , the degree of freedom of opening and closing the shielding plates 113, 123, 133, and 143, the first and second shielding plates 154 and 155 is increased, and after opening, the shielding plates 113 and 123 are elastically restored. , 133, 143, and the first and second shielding plates 154, 155 return to the original closed state. Note that the shaft portion 141a described in the fourth embodiment may not be an elastic member.

Further, in the first reference example, it has been described that the wall bodies 13 and 14 are disposed as a pair of both-end shielding portions that shield both ends of the passage 4 in the longitudinal direction. It is not limited.
10 and 11 show a modification of the both-end shielding part. As shown in FIG. 10, the both-end shielding portion 160 is formed at the end of the shielding plates 113, 123, 133, and 143 of the shielding bodies 11, 21, 31, and 41 along the longitudinal direction of the passage 4. A beam portion 161 arranged to extend in the direction, and an entrance / exit shielding member 162 that has flexibility and is attached to the beam portion 161 and shields both ends of the passage 4 so as to be openable and closable. .

  As shown in FIG. 11A, the beam portion 161 has, for example, a rectangular tube shape, extends along the width direction, and has a main body 161a having a space in which the entrance / exit shielding member 162 can be wound and housed. The winding shaft 161b is disposed in the main body 161a, has a round cylindrical shape or a round bar shape, extends along the width direction, and is rotatably attached around the axis. In addition, a slit (not shown) extending along the width direction is formed in the lower surface portion of the main body 161a, and an entrance / exit shielding member 162 is inserted through the slit. Further, an entrance / exit shielding member 162 is wound around the outer peripheral surface of the winding shaft 161b.

  The main body 161a of the beam portion 161 and the end portions of the shielding plates 113, 123, 133, and 143 are connected to each other by a mounting bracket 164 having a flat plate shape or an L-shaped cross section. Specifically, the mounting bracket 164 is fixed to the main body 161a and the end portion by screwing, welding, screwing, or the like. In this way, the beam portion 161 and the entrance / exit shielding member 162 are supported by the shielding plates 113, 123, 133, and 143.

  Further, the entrance / exit shielding member 162 has a substantially rectangular shape and is made of a flexible sheet-like or screen-like member, and can be stored in a state of being wound inside the main body 161a of the beam portion 161. In addition, as the entrance / exit shielding member 162, it is preferable to use a material that does not allow gas to pass through, that is, a material having a certain level of airtightness.

  Further, the entrance / exit shielding member 162 is supported by the beam portion 161 at the upper portion in the vertical direction, and the lower end edge portion 162a is exposed to the lower side of the main body 161a. Specifically, the end edge portion 162a has a round bar shape extending in the width direction, and an outer diameter thereof is set to be equal to or larger than the width of the slit of the main body 161a. With such a configuration, the end edge 162a cannot be inserted into the slit, and always protrudes to the lower side of the main body 161a.

  Further, the entrance / exit shielding member 162 accommodated in the main body 161a can shield the end portion of the passage 4 by vertically pulling out the end edge portion 162a protruding from the slit, and the end edge portion 162a up and down. It can be opened and closed by moving it.

  Further, the both-end shielding portion 160 includes a pair of guide rails (guide members) 163 disposed on the racks 3 and 33 corresponding to the edge portions in the width direction of the entrance / exit shielding member 162. These guide rails 163 can accommodate the end edge portions of the entrance / exit shielding member 162, respectively, and restrict the movement of the end edge portions as will be described later. The guide rails 163 are respectively arranged on the side surfaces of the racks 3 and 33 facing each other at the end of the passage 4 and are provided so as to extend in the vertical direction. The guide rail 163 is formed in, for example, a C-shaped cross section or a U-shaped cross section, and the end edge portion is accommodated in the recessed portion. Further, as shown in FIG. 11A, a slight gap is formed between the upper end portion of the guide rail 163 and the main body 161a of the beam portion 161.

  Although not shown, an engagement portion is provided at an end edge in the width direction of the entrance / exit shielding member 162, and the engagement portion is engaged with the guide rail 163 in the recess of each guide rail 163. Has been. Specifically, in the guide rail 163, the end edge portion in the width direction of the entrance / exit shielding member 162 is allowed to move in the vertical direction with respect to the guide rail 163, but is restricted from moving in the direction other than the vertical direction. Thus, the guide rails 163 are engaged with each other and are not easily separated from each other.

  When such a configuration is used, since the pair of both end shielding portions 160 that shield both ends of the passage 4 are provided, the space in the passage 4 and the external space of the passage 4 are reliably partitioned. Therefore, it is possible to prevent the heated air (hot air) after cooling the racks 3 and 33 from flowing into the passage 4 without flowing toward the air conditioner 6. Further, since the space in the passage 4 and the installation space of the air conditioner 6 are also reliably partitioned, the cooling air in the passage 4 is air conditioned without cooling the equipment in the racks 3 and 33. Recirculation to the device 6 is prevented.

  In other words, the cooling air in the passage 4 can be reliably sent into the racks 3 and 33, and the hot air discharged from the racks 3 and 33 flows reliably toward the air conditioner 6. Therefore, since the amount of cool air from the air conditioner 6 can be minimized, the cooling efficiency of the air conditioner 6 is improved.

  Further, since the entrance / exit shielding member 162 shields both ends of the passage 4 so as to be openable and closable, when the maintenance is performed on the racks 3 and 33 and the internal devices in the passage 4, the entrance / exit shielding member 162 is opened and closed. Thus, it is possible to easily enter and exit the passage 4.

  In addition, since the end edge portion in the width direction of the entrance / exit shielding member 162 is engaged with the guide rail 163 while being accommodated in the guide rail 163, it is used for cooling in the passage 4 in the vicinity of the end edge portion. Air is prevented from leaking into the external space of the passage 4. Therefore, the airtightness of the space in the passage 4 with respect to the external space is sufficiently ensured. Further, when the doorway opening / closing member 162 is opened and closed, the end edge portion is not separated from the guide rail 163, and excessive leakage of cooling air in the passage 4 is suppressed. Further, even if the internal pressure of the passage 4 changes due to the operation of the air conditioner 6, the end edge portion is not easily separated from the guide rail 163, and the sealed state of the passage 4 is suitably maintained.

  Further, the beam portions 161 of the both-end shielding portions 160 are disposed at the end portions of the shielding plates 113, 123, 133, and 143 of the shielding bodies 11, 21, 31, and 41 so as to extend in the width direction of the passage 4. Therefore, even if the racks 3 and 33 facing each other across the passage 4 due to an earthquake or the like are displaced in different directions, the relative movement between the beam 161 and the racks 3 and 33 is allowed, and the beam 161 and the rack 3 are allowed to move. 33 are prevented from being damaged.

Moreover, since the entrance / exit shielding member 162 of the both-end shielding portion 160 has flexibility, it can be deformed with respect to the displacement as described above, and the entrance / exit shielding member 162 is prevented from being damaged.
Further, during the displacement of the racks 3 and 33, the edge portion in the width direction of the entrance / exit shielding member 162 is locked to the guide rail 163, so that the flap of the entrance / exit shielding member 162 is suppressed, and the entrance / exit shielding member 162 A gap is hardly generated between the racks 3 and 33.

  In addition, since a gap is provided between the upper end portion of the guide rail 163 and the main body 161a of the beam portion 161, for example, as shown in FIG. 11B, the shielding plates 113, 123, 133, and 143 are provided. Even when a displacement that moves along the longitudinal direction of the passage 4 occurs with respect to the racks 3 and 33, damage to the beam portion 161, the entrance / exit shielding member 162, and the guide rail 163 is prevented. Specifically, since the beam portion 161 and the guide rail 163 are separated from each other, no stress is exerted, and as shown in the portion A in the figure, the entrance / exit shielding member 162 corresponds to the aforementioned displacement. Has become deformed.

  The guide rail 163 can be attached to and detached from the side surface so that the guide rail 163 is detached from the side surfaces of the racks 3 and 33 when the displacement increases to such an extent that stress is applied to the racks 3 and 33 and the beam portion 161. It is good also as arranging. Examples of such attachment means include a hook-and-loop fastener and a double-sided tape.

Further, as the entrance / exit shielding member 162, a flexible curtain-like member such as cloth may be used, and the entrance / exit shielding member 162 may be opened and closed in the width direction. In this case, a curtain rail or the like can be used as the beam portion 161. In addition, such a configuration can be used relatively easily in the above-described fifth reference example . That is, the beam portions 161 having lengths corresponding to these end portions are arranged at the end portions of the first and second shielding plates 154 and 155 of the shield 51 so as to correspond to these beam portions 161, respectively. By providing the entrance / exit shielding member 162, the both-end shielding part 160 can be configured relatively simply.

  When a curtain-like member is used as the entrance / exit shielding member 162, the width direction dimension of the entrance / exit shielding member 162 is set to be relatively large, and the edge portion of the entrance / exit shielding member 162 in the width direction is By sufficiently covering the side surfaces of the racks 3 and 33, a more sealed space is secured. That is, the airtightness of the space in the passage 4 with respect to the external space is surely increased, and excessive leakage of cooling air is suppressed, which is more preferable. Moreover, when using the some entrance / exit shielding member 162, it is preferable to arrange | position so that the said edge parts which these entrance / exit shielding members 162 adjoin may mutually cover.
