Embodiments of the present invention will be described below.
First, the structure of the housing of the electric device storage box will be described. As shown in FIGS. 1 and 2, the casing has a frame structure, and a frame body is formed from four vertical vertical frames 1, four depth frames 2, and four horizontal frames 3. Has been. A mounting angle 4 for mounting a device such as a device unit 7 to be described later is erected vertically at a position slightly inside the vertical frame 1. As in the conventional case, the opening of the frame body is covered with a door, a side plate 5 and a ceiling plate 6. However, the door is omitted in all the drawings of the present application.

  Reference numeral 7 denotes a device unit for releasing heat, such as a server, and has a cold air inlet 8 and a warm air outlet 9 on the left and right side surfaces as shown in FIG. The device unit 7 of the present embodiment is the right side intake and the left side exhaust of FIG. 4 and is arranged at equal intervals in the vertical direction. However, it is of course possible to use left side intake and right side exhaust. The space between the device units 7 and 7 is covered with a blank panel (not shown). Note that the device unit 7 may be any device that has the cold air inlet 8 or the warm air outlet 9 on at least one of the left and right side surfaces.

  As shown in FIG. 1, in the present embodiment, the cold air is sucked from the front surface of the housing, enters the cold air inlet 8 of the equipment unit 7 through the air supply duct 10 of the present invention described below, and It passes through the inside and is exhausted from the warm air discharge port 9 to the back side of the housing 1. It is also possible to supply cool air from the back surface of the casing and to discharge it from the front surface. In this case, the front-rear relationship of this embodiment may be changed.

  As shown in FIG. 4, the space between the left and right mount angles 4 and the side plates 5 in front of the housing is sealed by a shield plate 11 that blocks ventilation between the front and rear of the housing. The shape of the shield plate 11 is as shown in FIG. 6, and includes a surface 11A extending in the front-rear direction and a surface 11B having its end bent at a right angle. As shown in FIG. 3, a plurality of openings 12 are formed on the surface 11 </ b> B of the shield plate 11. These openings 12 have a structure that can be shielded by a detachable shielding member 13. The shield plate 11 is symmetrical.

  In this embodiment, as shown in FIG. 3 and FIG. 4, the shielding member 13 is removed on the right side of the casing where the cool air inlet 8 of the device unit 7 is located so that the cool air can be sucked from the front of the casing. It has become. However, on the left side of the casing where the warm air discharge port 9 of the device unit 7 is located, the opening 12 is shielded by the shielding member 13 so that the warm air does not flow out to the front side of the casing.

  In this embodiment, a top shield plate 14 as shown in FIG. 6 is attached to fill a gap generated between the ceiling plate 6 and the mount angle 4. The top shield plate 14 is screwed to the left and right shield plates 11.

  The device unit 7 is attached to the front or rear mount angle 4. In this embodiment, in order to support the load of the device unit 7, as shown in FIG. 5, the device unit support member 15 is disposed so as to cross between the front and rear mount angles 4, 4, and the left and right ends of the device unit 7 are supported. ing. The equipment unit support member 15 has an L-shaped cross section. Therefore, the device unit support member 15 can support the device unit 7 regardless of the shape of the device unit 7 in the front-rear direction, that is, the depth size. Furthermore, since the load of the equipment unit 7 can be supported, when the equipment unit 7 is attached only to the mount angle 4, the load of the equipment unit concentrates on the attachment part of the mount angle 4 when an earthquake or the like occurs. Although the mount angle 4 may be deformed, the load of the device unit 7 can be supported by the device unit support member 15, so that the seismic performance can be improved. The device unit support member 15 is provided with an attachment position changing portion 22 in which a later-described sealing plate 19 is attached to the back side of the device unit 7 and a plurality of attachment holes are formed so that the attachment position can be changed before and after. ing. When the device unit support member 15 is attached to the mount angle 4, a space is generated between the mount angle 4 and the device unit support member 15. Therefore, a shield member 15a having an L-shaped cross section is formed at both ends of the device unit support member 15 to prevent cold air from leaking.

  Next, the air supply duct 10 of the present invention will be described. The air supply duct 10 is formed by a guide angle 18, a sealing plate 19, and the side plate 5. The guide angle 18 includes the above-described device unit support member 15 and an L angle 20 fixed thereto. The L angle 20 is closer to the side plate of the housing than the mount angle 4 as shown in FIG. , And the tip thereof is in contact with or close to the side plate 5. The L angle 20 extends in the front-rear direction of the housing so as to abut or approach the front and rear mount angles 4, 4. Further, the L angle 20 is provided as a pair on the upper and lower surfaces of the device unit 7. For this reason, the L angle 20 projects horizontally from the upper and lower surfaces of the device unit 7 and constitutes the upper and lower surfaces of the air supply duct 10 inside the side plate 5.

  However, since the rear end of the air supply duct 10 remains open only by this, as shown in FIG. 8, the sealing plate extends across a pair of upper and lower guide angles 18, 18 formed on the back surface of the equipment unit 7. 19 is attached and the rear end is sealed. As a result, an air supply duct 10 is formed between the side plate 5 and the device unit 7, with the upper and lower surfaces closed by the L angle 20 of the guide angle 18 and the rear end closed by the sealing plate 19. This air supply duct 10 is formed only on the right side of the casing where the cool air inlet 8 of the device unit 7 is located, and cool air supplied from the front surface of the casing as shown in FIG. Intake and supply air to the cold air inlet 8 of the device unit 7. The warm air passing through the inside of the device unit 7 and discharged from the warm air discharge port 9 flows inside the side plate 5 as shown in FIG. 4, and is discharged from the back side of the device unit 7 to the outside of the casing. The sealing plate 19 may be directly attached to the device unit 7.

  Thus, the air supply duct 10 of the present invention is not formed in advance as in the prior art, but the L angle 20 is arranged at the upper and lower positions of the device unit 7, and the sealing plate 19 is provided on the back of the device unit 7. It is formed inside the side plate 5 simply by being attached. Moreover, since it can form irrespective of the length of the equipment unit 7, it is not necessary to form an air supply duct according to the size of the equipment unit 7 unlike the past. In addition, even if the device unit 7 or other communication device is previously mounted in the mount angle 4 or the housing, the air supply duct 10 can be easily formed.

  Since the L angle 20 is fixed to the device unit support member 15, a space is generated between the shield plate 11 and the end of the L angle 20. Therefore, the shielding member 21 shown in FIG. 9 is fixed to the L angle 20 to prevent the leakage of cold air as shown in FIG. The shielding member 21 may be formed integrally with the L angle 20.

  In the above embodiment, the sealing plate 19 is attached between the pair of upper and lower guide angles 18, 18 formed on the back surface of the device unit 7. However, by separately forming the sealing plate 19, Even when the direction shape and depth size change, it can be easily changed. Further, as shown in FIG. 11, the fixing portion of the sealing plate 19 is set as a long hole-like attachment position changing portion 22, and the sealing plate 19 is slid in the front-rear direction in accordance with the size of the device unit 7. It is also possible to fix at a position corresponding to the size.

  In the above embodiment, the sealing plate 19 is formed on the back surface of the device unit 7 so as to form a cold air flow path toward the cold air inlet 8 of the device unit 7 through the opening 12 on the front side. However, as shown in FIG. 12, the device unit 7 may be attached to the mount angle 4 on the back side of the housing, and the left and right ends on the front side of the device unit 7 may be supported by a pair of upper and lower guide angles 18. In this embodiment, the sealing plate 19 is formed so as to form a warm air flow path from the warm air discharge port 9 of the device unit 7 toward the back surface of the housing. By forming the sealing plate 19 on the front surface of the equipment unit 7 at the warm air discharge port 9, it is possible to prevent cold air and warm air from being mixed and to easily form an air supply duct. A shield plate 11 is provided on the rear surface of the housing so that the opening 12 on the cold air inlet 8 side is covered with the shielding member 13, and warm air from the warm air outlet 9 is transferred to the rear surface of the housing through the opening 12. It is what is discharged.

  As described above, according to the present invention, it is possible to provide an air supply duct that has a simple structure, can be installed after the equipment unit 7 is attached, and is not affected by the size of the equipment unit 7. .
