The ventilation port 23 provided in the door body 22 is arranged so as to be oblique to the direction of the exhaust port 41 of the air conditioning equipment 4. Therefore, it is possible to provide a structure capable of introducing cooling air into the electric / electronic equipment storage box 2 on the air conditioning equipment 4 side on the upstream side.

The server room 1 of the embodiment is provided in one room of the building. Inside the server room 1, a plurality of boxes 2 for storing electrical and electronic devices are arranged in a row. The electrical / electronic device storage box 2 includes a housing body 21 on which electrical / electronic devices such as a server and a power supply unit are mounted, and a door body 22 that covers the opening thereof. An air conditioner 4 is provided inside the server room 1.

Inside the server room 1, a separator 18 provides a hot aisle 11 for discharging air from a box 2 for storing electrical and electronic equipment such as a rack, and a cold aisle 11 serves as a cooling space for cooling air emitted from the air conditioning equipment 4. It is divided into 12 parts, and the heat of the hot aisle 11 is discharged to the outside of the server room 1 from the exhaust port 41 and the exhaust equipment provided in the server room 1. The door body 22 located on the front side of the electric / electronic device storage box 2 is arranged in the cold door aisle 12. In the embodiment, each of the electric / electronic device storage boxes 2 arranged in a row is connected to the adjacent electric / electronic device storage boxes 2 by using a connecting member (not shown).

The surface of the door body 22 provided on the front side and the door body 24 provided on the back side of the electric / electronic device storage box 2 is provided with a vent 23 provided by using punching metal or the like. Air can enter and exit the electronic device storage box 2. Here, the vent 23 of the door body 22 facing the cold aisle 12 is on the intake side, and the vent 23 of the door body 24 facing the hot aisle 11 is on the exhaust side. In the examples shown in FIGS. 1 and 2, the directions in which the electrical and electronic equipment storage boxes 2 are lined up and the exhaust direction of the cooling air protruding from the exhaust port 41 of the air conditioning equipment 4 are parallel in a plan view, but in a row. In all of the electrical and electronic equipment storage boxes 2 lined up in the above, when the door body 22 is closed, the door body 22 is diagonally fixed to the housing body 21. Each of the door bodies 22 is non-parallel to the exhaust direction of the cooling air protruding from the exhaust port 41 of the air conditioning equipment 4, so that the cooling air easily enters the ventilation port 23 provided in the door body 22.

In the examples shown in FIGS. 1 and 2, cooling air is discharged from the exhaust port 41 of the air conditioner 4 between the two rows in which the electrical and electronic equipment storage boxes 2 are arranged. The door body 22 of each electric / electronic device storage box 2 is directed toward the cooling air path on the downstream side of the flow of the cooling air discharged from the exhaust port 41 of the air conditioning equipment 4 than on the upstream side. It is configured to protrude. Therefore, the electrical and electronic equipment storage boxes 2 arranged on both ends of the cooling path discharged from the air conditioner 4 are formed so as to be symmetrical when viewed from above. The row of such electric / electronic equipment storage boxes 2 may be one row.

As the door body 22 of the electric / electronic device storage box 2, an existing door body 22 having a flat plate-shaped surface formed parallel to the opening of the housing body 21 can be used. In this case, it is preferable to attach the side covering portion 51 to the side of the housing main body 21 away from the air conditioning equipment 4. Further, it is preferable that the handle 29 of the door body 22 and the lock bar interlocking with the handle 29 can be locked to the tip of the side covering portion 51.

In this way, the electrical and electronic equipment storage boxes 2 arranged so that the direction of the ventilation port 23 provided in the door body 22 is oblique to the direction of the exhaust port 41 of the air conditioning equipment 4 are shown in FIGS. 1 to 3. As can be understood from the above, at a position downstream of the door body 22, the side covering portion 51 extending in the vertical direction is configured to cover the space between the surface of the door body 22 and the housing body 21. It is preferable to do so. By providing the side covering portion 51, the cooling air introduced from the vent 23 of the door body 22 can be easily taken into the inside of the electric / electronic device storage box 2, and the cooling of the housing body 21 side is efficient. Can be.

Further, the electric / electronic device storage box 2 arranged so that the direction of the ventilation port 23 provided in the door body 22 is oblique to the direction of the exhaust port 41 of the air conditioning equipment 4 is understood from that shown in FIG. As described above, the covering portion 61 extending in the left-right direction is configured to cover the space between the upper surface of the door body 22 and the housing body 21, and the space between the lower surface of the door body 22 and the housing body 21. Is preferable. By eliminating the gap between the door body 22 and the housing body 21 for human hands to enter, it is possible to prevent the cooling air taken in from the vent 23 of the door body 22 from being discharged to the outside of the housing body 21. , Security performance can be improved. In the example shown in FIG. 3, a covering portion 61 that covers the space between the upper part of the door body 22 and the housing body 21, a covering portion 61 that covers the space between the lower part of the door body 22 and the housing body 21, and a side coating. The portion 51 is fixed to the housing body 21.

As can be understood from FIG. 4, the door body 22 has a form in which the thickness differs between the rotation shaft side and the handle 29 side, and the surface of the door body 22 is in the width direction of the housing body 21. It may be configured to be inclined diagonally with respect to the relative. By doing so, it is not necessary to separately provide a member constituting the side covering portion 51.

By the way, on the downstream side of the flow of the cooling air discharged from the air conditioning equipment 4, the speed of the cooling air passing in front of the electric / electronic device storage box 2 is lower than that on the upstream side. Therefore, with respect to the electric / electronic device storage box 2 arranged on the downstream side, cooling air can be drawn in by a fan or the like provided in the electric / electronic device inside the electric / electronic device storage box 2. Therefore, as shown in FIG. 5, with respect to the electric / electronic device storage box 2 arranged on the downstream side, the inclination angle of the surface of the door body 22 is small, or the surface of the door body 22 is provided on the housing body 21. It may be parallel to the opening. In this way, the inclination angle of the surface of the door body 22 of the electric / electronic equipment storage box 2 located on the upstream side is larger than the inclination angle of the surface of the door body 22 of the electric / electronic equipment storage box 2 located on the downstream side. It may be made larger. By doing so, it is possible to prevent the electric / electronic device storage box 2 from becoming large on the downstream side. In the present embodiment, the inclination angle of the door body 22 on the downstream side of the flow of the cooling air discharged from the air conditioning equipment 4 is reduced, but only the temperature of the electric / electronic device storage box 2 on the way is high. In this case, the inclination angle of the door body 22 may be set at random, such as increasing the inclination angle of the door body 22 of the corresponding electric / electronic device storage box 2.

By the way, when the side covering portion 51 is detachable from the housing body 21 or the door body 22, the side covering portions 51 having a desired angle and different lengths are prepared from a plurality of side covering portions 51. If 51 and 71 are used, a desired angle can be set. Further, the side covering portion 51 may be rotatably held. In the case of such a configuration, by supporting the door body 22 by the side covering portion 51, the housing body 21 and the door body 22 form an angle, and the housing body 21 and the door body 22 do not form an angle. You can choose no normal form.

By the way, the server room system 100 of the present invention does not need to be limited to the above-described form. For example, as can be understood from FIG. 6, the exhaust port 41 may be left in the server room 1 while all or most of the air conditioning equipment 4 may be installed outside the server room 1. Further, as can be understood from FIG. 7, the air-conditioning equipment 4 is formed in the air-conditioning chamber 200, the exhaust port 41 of the server room 1 is not connected, and the cooling air is blown out into the server room 1. A chamber method may be adopted. The exhaust port 41 of the server room 1 and the air outlet of the air conditioning equipment 4 may be connected by a duct.

Further, as can be understood from FIG. 8, the electric / electronic device storage boxes 2 may be arranged so as to be obliquely oriented with respect to the direction in which the electric / electronic device storage boxes 2 are arranged. However, since the housing body 21 can be easily arranged and connected, and the separator 18 can be easily arranged, the housing body 21 is arranged so that the depth direction is perpendicular to the direction of the exhaust port 41 of the air conditioning equipment 4. It is preferable that the surface orientation of the door body 22 is oblique to the orientation of the exhaust port 41 of the air conditioning equipment 4.

As another embodiment, the server room system 100 as shown in FIGS. 9 and 10 can be used. The direction of the ventilation port 23 provided in the door body 22 is the direction of the exhaust port of the air conditioning equipment 4 so that the cooling air emitted from the exhaust port 41 of the air conditioning equipment 4 is introduced into the ventilation port 23 with the door body 22 closed. The structure is the same as that arranged so as to be oblique to the direction of 41, but the vent 52 is formed in the side covering portion 51. When the vent 52 is formed, a part of the cooling air taken into the housing body 21 can flow to the adjacent electric / electronic equipment storage box 2, so that the adjacent electric / electronic equipment storage box 2 is an air conditioning equipment. The temperature rise can be suppressed by the cooling air from 4 and the cooling air discharged from the electric / electronic device storage box 2. Further, in FIG. 9, it has been described that the vent 52 is formed in the side covering portion 51 formed separately from the door body 22, but as shown in FIG. 4, the thickness on the rotation shaft side and the handle 29 side is thick. A vent 52 may be formed in the door body 22 having a different shape.

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 in various modes.
