DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The following describes an embodiment of the invention. As can be understood from FIGS. 1 to 4, the electric / electronic device storage box assembly 1 of this embodiment is connected to electric / electronic device storage boxes 2 each having an equipment unit mounting portion 21 for mounting an equipment unit 99. In this electric / electronic device storage box assembly 1, "electrical / electronic device storage boxes 2 each having a shield plate 22 located at the boundary between the first area aa and the second area ab, and a cooling device 23 capable of cooling the air introduced from the second area ab side and sending the air to the first area aa side to cool the equipment unit 99" are connected to each other so that the opposing surfaces are open and air can move to each other's first area aa. In addition, a part of the shield plate 22 is disposed so as to be located between one equipment unit mounting portion 21 provided on one electric / electronic device storage box 2 and one equipment unit mounting portion 21 provided on another electric / electronic device storage box 2 located adjacent thereto. Therefore, even if one of the cooling devices 23 stops, the temperature of the equipment unit 99 provided inside the electric / electronic device storage box 2 can be suppressed from rising.

[0016] In the electrical / electronic device storage box assembly 1 shown in Fig. 1, a plurality of racks are connected. The racks, which are electrical / electronic device storage boxes 2, are provided with vertical frames 241 extending in the up-down direction, horizontal frames 242 extending in the left-right direction, and depth frames 243 extending in the front-rear direction, which form a rectangular parallelepiped frame body 24 (see Fig. 2). In the embodiment, a side panel 41, a ceiling panel 42, a bottom surface 43, and a door 44 are attached to the frame body 24 consisting of the vertical frames 241, the horizontal frames 242, and the depth frame 243. In the embodiment, the ceiling panel 42 is provided with a wiring section 11 for introducing and guiding wiring to the rack. The wiring section 11 is also provided with a drawstring-shaped flexible member 13 to prevent cool air and exhaust heat from leaking from the wiring section 11.

[0017] Inside the rack, a mount angle is provided as an equipment unit attachment section 21 used for attaching or mounting an equipment unit 99 such as a HUB or a server.

[0018] In the example shown in Fig. 2 and Fig. 3, a partition plate 25 is provided to separate the inside of the electric / electronic device storage box 2 into upper and lower parts. The partition plate 25 is provided so that the equipment unit mounting space ba, which is a space for mounting the equipment unit 99, is located above it, and the cooling device mounting space bb, which is a space for mounting the cooling device 23, is located below it, and is provided to restrict the flow of air in and out of the equipment unit mounting space ba and the cooling device mounting space bb. In the example shown in Fig. 2 and Fig. 3, a wiring section 1211 is provided to enable wiring to be led in and out from the equipment unit mounting space ba to the cooling device mounting space bb. The wiring section 12 provided on the ceiling and the partition plate 25 is provided with a pouch-shaped flexible member 13 to prevent cold air and exhaust heat from leaking from the wiring section 12. In the example shown in Fig. 2 and Fig. 3, a mount angle used as an equipment unit mounting section 21 is provided in the equipment unit mounting space ba.

[0019] 2 and 3, the partition plate 25 is provided with an intake port 251 and an exhaust port 252, which are openings. The intake port 251 and the exhaust port 252 are used to provide air flow for the cooling device 23. In this embodiment, the intake port 251 is located on the front side of the electric / electronic device storage box 2, and the exhaust port 252 is located behind the intake port 251.

[0020] In this example, air cooled by the cooling device 23 is brought to the upper side of the partition plate 25 through an air intake 251 provided on the front side of the partition plate 25. This brings the cooled air to the front side of the equipment unit 99. In order to make it easier for the cooled air to cool the equipment unit 99, the electric / electronic device storage box 2 is provided with a shield plate 22.

[0021] 4 and 5 are a vertical shield plate 22a extending in the up-down direction and a horizontal shield plate 22b extending in the left-right direction. The vertical shield plate 22a is provided to prevent the cooled air from escaping to the space on the equipment unit 99 side of the equipment unit mounting portion 21 located on the right or left side of the equipment unit 99. This configuration prevents the equipment unit 99 from becoming difficult to cool.

[0022] In the example shown in Figures 4 and 5, the one of the two vertical shield plates 22a located on the left side is arranged so as to divide the space between the equipment unit mounting part 21 located on the left side and the side plate 41 in the front-rear direction. The vertical shield plate 22a located on the right side is arranged so as to divide the space to the right of the equipment unit mounting part 21 located on the right side in the front-rear direction. In the example shown in Figures 4 and 5, the vertical shield plate 22a is attached to the mount angle which is the equipment unit mounting part 21, but this is not limited to such an example. For example, the vertical shield plate 22a may be attached to the side plate 41.

[0023] The area located in front of the vertical shield plate 22a is the first area aa, and the area located behind the vertical shield plate 22a is the second area ab, and the vertical shield plate 22a limits the route along which the cooled air moves from the first area aa to the second area ab, making it easier to cool the equipment unit 99. In addition, the vertical shield plate 22a inhibits the air heated by the equipment unit 99 from moving from the second area ab to the first area aa.

[0024] In the example shown in Figures 4 and 5, in addition to the vertical shield plate 22a, a horizontal shield plate 22b is provided. This horizontal shield plate 22b also facilitates cooling of the equipment unit 99 when the cooled air moves from the first area aa to the second area ab. In the example shown in Figures 4 and 5, the horizontal shield plate 22b is provided to suppress the cooled air from moving along the surface of the partition plate 25 when the cooled air moves from the first area aa to the second area ab. In this example, the horizontal shield plate 22b is disposed along the partition plate 25 so as to connect the vertical shield plates 22a located on the left and right.

[0025] The horizontal shield plate 22b may be installed to suppress the movement of the cooled air along the surface of the top plate when the cooled air moves from the first area aa to the second area ab. In this case, the horizontal shield plate 22b is preferably disposed directly below the top plate along the top plate so as to connect the vertical shield plates 22a located on the left and right sides.

[0026] Although the electrical and electronic equipment storage box 2 of the embodiment has mounting angles on both the front and rear sides, the shield plate 22 is disposed adjacent only to the mounting angle located on the front side of the electrical and electronic equipment storage box 2. In other words, the shield plate 22 is not disposed adjacent to the mounting angle located on the rear side of the electrical and electronic equipment storage box 2.

[0027] 4 and 5, the vertical shield plate 22a is provided with a wiring port 22a1 for wiring, and the wiring of the equipment unit 99 can be passed through the wiring port 22a1 in the front-rear direction. Note that the wiring port 22a1 is preferably configured to include a brush, a rubber packing, or the like that can be used to prevent leakage of cool air.

[0028] Incidentally, the cooling device 23 is stored in the cooling device mounting space bb, and in the example shown in Fig. 4 and Fig. 6, the cooling device 23 can be stored in the cooling device mounting space bb by removing the panel part 26 located below the door 44. The cooling device 23 is provided with an intake part 231 and an exhaust part 232, and is configured so that when the cooling device 23 is stored in the cooling device mounting space bb, the exhaust part 232 of the cooling device 23 faces the intake port 251 of the partition plate, and the intake part 231 of the cooling device 23 faces the exhaust port 252 of the partition plate at a position adjacent thereto. Therefore, even if the cooling device 23 is moved from the cooling device mounting space bb for replacement or inspection, etc., the air path can be secured by returning the cooling device 23 to its original position.

[0029] 7 shows an example of a duct portion 91 having a through-hole-like penetration portion. This duct portion 91 is detachable from the partition plate 25, and can be attached to the partition plate 25 using a bush.

[0030] Duct section 91 is attached to intake port 251 and exhaust port 252 of partition plate 25, and when cooling device 23 is mounted in electrical / electronic device storage box 2, it can prevent air from leaking from the gap between intake port 251 of partition plate 25 and intake section 231 of cooling device 23 and the gap between exhaust port 252 of partition plate 25 and exhaust section 232 of cooling device 23. To make this possible, duct section 91 is attached so that its lower end is located below partition plate 25 (see FIG. 8).

[0031] Furthermore, if a packing 911 is provided at the lower end of the duct portion 91, air leakage can be more effectively suppressed. Furthermore, when the cooling device 23 is disposed above the partition plate 25, it is preferable to provide a packing 911 at the upper end of the duct. Note that, when the air intake port 251 or the air exhaust port 252 of the partition plate 25 are not used, a cover member 92 having a bottom portion formed thereon may be prepared in order to close them (see FIG. 9).

[0032] 9 and 10, the support bracket 27 is disposed in the cooling device mounting space bb so as to be adjacent to the depth frame 243. The support bracket 27 is formed so as to extend in the front-rear direction of the electric / electronic device storage box 2, and the cooling device 23 can be mounted and fixed on this support bracket 27. The cooling device 23 may be of any type, and examples of the type include a plate-type heat exchanger, a heat pipe-type heat exchanger, a water-cooled heat exchanger, and an air conditioner.

[0033] The cooling device 23 of the embodiment includes a heat exchanger 233 and a ventilation fan 234, and the air heated in the equipment unit 99 is heat exchanged in the heat exchanger 233 of the cooling device 23, and the air cooled by the heat exchange is sent toward the equipment unit 99 (see FIGS. 10 and 11). The ventilation fan 234 is used to discharge condensation and drain water from the cooling device 23 to the outside of the housing. The ventilation fan 234 may also be used to discharge heat from the heat exchanger 233 to the outside via the intake port 251 and exhaust port 252 of the panel portion 26 of the electric / electronic device storage box 2.

[0034] 12 to 14 show a state in which rack A, which is one of the two electrical and electronic device storage boxes 2 provided in the electrical and electronic device storage box assembly 1, and rack B, which is the other electrical and electronic device storage box 2, are connected together. No side panel is provided on the connecting surface side of each rack.

[0035] If a part of the shield plate 22 is arranged so as to be located between one equipment unit mounting portion 21 provided in one electric / electronic device storage box 2 and one equipment unit mounting portion 21 provided in another electric / electronic device storage box 2 located adjacent thereto, the cooling air is prevented from escaping between the equipment unit mounting portions 21. This effect can also be obtained by attaching the shield plate 22 to only one of the equipment units 99. In this case, it is preferable that the left-right length of the shield plate 22 is equal to or greater than the left-right length between the equipment unit mounting portions 21.

[0036] 12 to 14, a shield plate 22 is attached to both of the equipment unit mounting portions 21. In this case, the shield plates 22 are configured to be adjacent to each other. At the locations where the shield plates 22 are adjacent to each other, it is preferable that the shield plates 22 are configured to abut against each other from the left and right direction, and it is also preferable that the shield plates 22 are configured so that parts of them overlap in the front-rear direction.

[0037] As can be seen from these examples, it is preferable that a shield plate 22 attached to one equipment unit mounting portion 21 provided in one electrical / electronic device storage box 2 is adjacent to a shield plate 22 attached to one equipment unit mounting portion 21 provided in another electrical / electronic device storage box 2 located adjacent to it.

[0038] In addition, the first areas aa of the racks are formed to communicate with each other. The cooling device 23 (cooling device A) provided in one rack A not only sends cool air to the equipment unit 99 (equipment unit A) of the rack A, but can also send cool air to the equipment unit 99 (equipment unit B) of the other rack B. Therefore, even if the cooling device 23 (cooling device B) provided in the rack B breaks down, the cooling device 23 (cooling device A) provided in the rack A can send cool air to the equipment unit 99 (equipment unit B) of the other rack B, and the equipment unit 99 mounted in the rack can be prevented from becoming hot.

[0039] In the example shown in Fig. 14, a deformable shield packing 19 is provided between the vertical shield plates 22a. This makes it possible to fill the gaps between the vertical shield plates 22a. It also makes it possible to absorb size errors.

[0040] As can be seen from this example, it is preferable to have a configuration in which a shielding gasket 19 is provided between a shielding plate 22 provided on a first electrical / electronic device storage box 2, which is one of adjacent electrical / electronic device storage boxes 2, and a shielding plate 22 provided on a second electrical / electronic device storage box 2, which is the other.

[0041] Incidentally, when one cooling device 23 stops, it is preferable to increase the air volume or improve the cooling capacity of the other cooling device 23. In addition, as a method for detecting the stop of the cooling device 23, for example, a configuration in which each rack is provided with a temperature sensor 31 (see FIG. 15) can be used, and when it is detected that the temperature difference between the racks has increased or that only the temperature of the equipment unit 99 of one rack has exceeded a predetermined temperature, it can be determined that there is a problem such as the stop of the cooling device 23. When such a situation occurs, it is preferable to control the cooling device 23 that is not causing a problem to increase the air volume or cooling capacity.

[0042] Also, the cooling device 23 (cooling device A) and the cooling device 23 (cooling device B) may be made capable of communicating with each other, and when the communication signal is interrupted, it may be determined that the cooling device 23 of the other rack has stopped. To make this possible, the cooling device 23 (cooling device A) and the cooling device 23 (cooling device B) may be connected by a communication line 32. Of course, the method of detecting the stop of the cooling device 23 is not limited to the above.

[0043] When one of the cooling devices 23 stops, the air volume or cooling capacity of the cooling device 23 may be increased, and when the temperature of one of the equipment units 99 reaches or exceeds a predetermined temperature, the cooling capacity of the operating cooling device 23 may be further increased. For example, the graph shown in Fig. 16 shows an example in which the cooling device 23 is an air conditioner, and the set temperature is changed for each stage.

[0044] Specifically, the set temperature was 25 degrees, but when it was detected that the cooling device 23 had stopped, the set temperature of the cooling device 23 that was not stopped was reset to 23 degrees, and then, since it was confirmed that the temperature of the equipment unit 99 was equal to or higher than a predetermined value, the set temperature of the cooling device 23 that was not stopped was reset to 20 degrees. Of course, the set temperature is not limited to this example, and the timing at which the temperature setting is changed is not limited to this example either.

[0045] Meanwhile, protection of the equipment unit 99 can also be assisted by something other than the cooling device 23. For example, when it is determined that one of the cooling devices 23 has stopped, in addition to controlling the cooling device 23, the air volume of the ventilation fan 991 of the equipment unit 99 of the rack mounting the stopped cooling device 23 may be increased to make it easier to take in the air volume of the other cooling device 23. Also, when one of the cooling devices 23 stops, the air volume of the ventilation fan 991 of the equipment unit 99 and the air volume and cooling capacity of the other cooling device 23 may be increased.

[0046] It is also preferable to configure the equipment unit 99 so that it can be controlled by connecting the cooling device 23 and the equipment unit 99 with a communication line 33 and by connecting the temperature sensor 31 and the equipment unit 99 with a communication line 34 (see Figs. 17 and 18). Since a stop or failure of the cooling device 23 can be immediately detected, the possibility of thermal runaway of the equipment unit 99 can be reduced.

[0047] However, the cooling device 23 may stop not only due to a malfunction of the cooling device 23. The cooling device 23 may stop due to an interruption of the commercial power supply or the tripping of the main breaker of the distribution board.

[0048] Considering this, it is preferable to connect each cooling device 23 to different systems rather than connecting each cooling device 23 to one system. If the cooling devices 23 are configured to be connected to different systems, if the power supply of one system is lost but the power supply of the other systems is operating, there is a possibility that one of the cooling devices 23 will operate, so it is possible to reduce the impact on the equipment units 99 mounted thereon. Of course, in addition to that, the system of the equipment units 99 may be separated from the system of the cooling devices 23. Note that in this invention, the systems are not identified only in terms of commercial power supply and distributed power supply. Even if the same commercial power supply is used, if they are connected to different distribution boards, they are considered to be separate systems.

[0049] 19, the distribution board connected to the cooling device 23 provided in one electric / electronic device storage box 2 is different from the distribution board connected to the cooling device 23 provided in the other electric / electronic device storage box 2. In addition, the distribution board connected to the equipment unit 99 is configured to be different from the distribution boards connected to each cooling device 23.

[0050] 20 shows that electricity is sent from a plurality of distribution boards provided in a building to the electrical and electronic equipment storage box assembly 1. In this example, too, the distribution board connected to the cooling device 23 provided in one electrical and electronic equipment storage box 2 is different from the distribution board connected to the cooling device 23 provided in the other electrical and electronic equipment storage box 2.

[0051] As can be understood from these descriptions, it is preferable that the cooling devices 23 of each electrical and electronic device storage box 2 are connected to different power supply systems. It is also preferable that each electrical and electronic device storage box 2 is configured such that the equipment unit 99 and the cooling devices 23 are connected to different power supply systems. It is also preferable that the cooling devices 23 of each electrical and electronic device storage box 2 are configured such that they are connected to different distribution boards.

[0052] The possibility that the equipment units 99 cannot be cooled is reduced by providing the electrical and electronic equipment storage box assembly 1 with a plurality of electrical and electronic equipment storage boxes 2 each equipped with a cooling device 23, but the maximum number of equipment units 99 is not always mounted in the electrical and electronic equipment storage box 2. In this case, if air moves from the first area aa to the second area ab through a space where no equipment units 99 are mounted, the cooling efficiency of the equipment units 99 decreases.

[0053] In order to avoid this, if there is a space above or below the equipment unit 99 where the equipment unit 99 is not installed, it is preferable to place a blanking panel 28 on the boundary between the first area aa and the second area ab in that space (see FIG. 21). The blanking panel 28 is preferably fixed so as to span between the vertical shielding plates 22a located on the left and right sides of the electric / electronic device storage box 2.

[0054] If it is desired to add an equipment unit 99 later, the blank panel 28 can be removed and the equipment unit 99 can be attached (see FIG. 21). If there is space where an equipment unit 99 is not installed, the cooling capacity of the cooling device 23 can be reduced to reduce power consumption. It is preferable that the space where an equipment unit 99 is not installed is located above the equipment unit 99, not below it. This is because the equipment unit 99 is located near the cooling device 23 so that the air volume of the cooling device 23 formed below can be easily transmitted to the equipment unit 99.

[0055] A configuration in which the equipment unit 99 can be cooled by another cooling device 23 even when one cooling device 23 cannot be used is also effective in performing periodic inspections of the cooling devices 23. For example, even when one cooling device 23 is stopped and inspected, the other cooling device 23 can be operated to cool the equipment unit 99. Therefore, the cooling devices 23 can be inspected without stopping the equipment unit 99. In this case, it is possible to restrict the air path with a cover member 92 or other member as shown in FIG. 9, but when it is only necessary to move the cooling device 23 slightly as shown in FIG. 22, the cooling device 23 can also restrict the air path.

[0056] It is also possible to realize rotational operation of the cooling devices 23. This allows planned maintenance operation, such as staggering the replacement timing of the cooling devices 23.

[0057] 1 shows an example of an electrical / electronic device storage box assembly 1 in which only two electrical / electronic device storage boxes 2 are connected together, but an electrical / electronic device storage box assembly 1 in which three or more electrical / electronic device storage boxes 2 are connected together may also be used (see FIG. 23). In this case, the electrical / electronic device storage box 2 sandwiched between other electrical / electronic device storage boxes 2 may have no side panels attached to both sides thereof.

[0058] 1 to 3, the cooling device mounting space bb, which is the storage space for the cooling device 23, is provided on the bottom surface 43 side of the box 2 for storing electrical electronic equipment, but this is not limited to this example. For example, the cooling device mounting space bb may be provided on the ceiling side of the box 2 for storing electrical electronic equipment. However, if the cooling device mounting space bb is provided on the bottom surface 43 side, inspection of the cooling device 23 can be facilitated.

[0059] In the examples described above, the cooling device 23 is provided inside the frame body 24, which is made up of the vertical frame 241, the horizontal frame 242, and the depth frame 243. With such a configuration, the box can be made the same size as other electric / electronic device storage boxes 2, and can have an appearance that is integrated with other electric / electronic device storage boxes even when placed next to them.

[0060] On the other hand, it is also possible to provide the cooling device 23 outside the frame body 24. For example, it is possible to provide a configuration in which a base 93 is disposed below the frame body 24, and the cooling device 23 is provided inside the base 93. For example, it is possible to provide an electric / electronic device storage box 2 having a structure in which a rack and a base 93 disposed below the rack are connected to each other (see FIGS. 24 and 25).

[0061] For example, the cooling device 23 is mounted inside the base 93, and a plate material 94 adjacent to the horizontal frame 242 and the depth frame 243 located on the bottom surface 43 side of the rack serves as a partition plate. In this example, this plate material 94 may be provided with an intake port 251 and an exhaust port 252 corresponding to the cooling device 23 stored in the base 93. Note that, although one side plate 41 is configured to cover both the rack and the base 93 in Fig. 24, such a configuration is not essential.

[0062] In the above explanation, the electric / electronic device storage box assembly 1 in which the electric / electronic device storage boxes 2 are connected has been explained, but the electric / electronic device storage box 51 may have a similar configuration to the electric / electronic device storage box assembly 1. For example, a single rack may be configured to have a plurality of cooling devices 23, and the shield plate 22 is disposed between two mounting angles 71 provided on the front side of the rack and near the center of the rack when viewed from the front (see Figs. 26 to 29). Also, a part of the shield plate 22 is disposed between one mounting angle 71 provided in one equipment unit mounting area 52 and one mounting angle 71 provided in another equipment unit mounting area 52 located adjacent thereto.

[0063] In this example, two equipment unit mounting areas 52 each equipped with a mounting angle 71 are provided inside the frame body 24, but it is also possible to provide three or more equipment unit mounting areas 52. In any case, the electrical / electronic device storage box 51 has an equipment unit mounting area 52 adjacent to another equipment unit mounting area 52.

[0064] Each equipment unit mounting region 52 is provided with a cooling device 23 capable of cooling the equipment units 99. The cooling device 23 can cool the equipment units 99 by cooling the air introduced from the second area ab side and sending the air to the first area aa side. A shield plate 22 is located at the boundary between the first area aa and the second area ab, and restricts the movement path of the air before cooling the equipment units 99 and the air heated by the equipment units 99, similar to the electric / electronic equipment storage box assembly 1. Air can move between the equipment unit mounting regions 52 to each other's first areas aa.

[0065] As can be seen from this example, the box 51 for storing electrical and electronic equipment has equipment unit mounting areas 52, each equipped with a mounting angle 71 for mounting an equipment unit 99, positioned adjacent to each other, and each equipment unit mounting area 52 is equipped with a shield plate 22 positioned on the boundary between the first area aa and the second area ab, and a cooling device 23 capable of cooling the equipment unit 99 by cooling air introduced from the second area ab side and sending the air to the first area aa side, so that air can move between the first areas aa, and it is preferable that a part of the shield plate 22 is positioned between one mounting angle 71 provided in one equipment unit mounting area 52 and one mounting angle 71 provided in another equipment unit mounting area 52 positioned adjacent to it.

[0066] 26 to 29, the rack is provided with a partition plate 25 that separates the rack into upper and lower portions, and the partition plate 25 is provided with an intake port 251 and an exhaust port 252. In addition, a cooling device 23 is disposed below the partition plate 25.

[0067] In the explanation so far, the box for storing electric / electronic devices is provided with a partition plate 25 for dividing the internal space thereof, and the partition plate 25 is provided with an intake port 251 and an exhaust port 252, but such a partition plate 25 is not essential (see FIG. 30). For example, when the partition plate 25 is not provided, the exhaust port 252 of the cooling device 23 may be located in the first area aa, and the intake port 251 may be located in the second area ab. Even in this case, the cooling effect of the equipment unit 99 is enhanced by the shield plates 22, such as the vertical shield plate 22a and the horizontal shield plate 22b, located on the boundary between the first area aa and the second area ab, as has already been explained.

[0068] In this case, the vertical shield plate 22a is preferably configured to extend from the ceiling plate 42 to the bottom surface 43 of the electrical / electronic device storage box 51, and the horizontal shield plate 22b is preferably configured to be adjacent to the upper surface of the cooling device 23. It is further preferable that the horizontal shield plate 22b is configured to abut against the upper surface of the cooling device 23.

[0069] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be modified in various ways. For example, the shield plate does not have to be provided with a vertical shield plate and a horizontal shield plate separately, and the shield plate can be configured in a frame shape.
