Hereinafter, embodiments of the present invention will be described.
First, the structure of the housing of the electrical device storage box will be described. As shown in FIGS. 1 and 2, the casing has a frame structure, and a frame is formed by four vertical vertical frames 1, four depth frames 2, and four horizontal frames 3. It is done. A mounting angle 4 for mounting a device such as a device unit 7 described later is provided vertically at a position slightly inward of the vertical frame 1. As in the prior art, the opening of the frame body is covered with the door, the side plate 5 and the ceiling plate 6. However, the door is omitted in the drawings of the present application.

  Reference numeral 7 denotes an equipment unit for releasing heat such as a server, and as shown in FIG. 4, has cold air inlets 8 and warm air outlets 9 on the left and right sides. The equipment unit 7 of this embodiment is the right intake and the left exhaust in FIG. 4 and is disposed at equal intervals in the vertical direction. However, it is of course possible to use left intake and right exhaust. The device units 7 are covered with a blank panel or the like (not shown). The device unit 7 may be any device having the cold air intake port 8 or the warm air exhaust port 9 on at least one of the left and right side surfaces.

  As shown in FIG. 1, in the present embodiment, cold air is drawn from the front of the casing and enters the cold air intake port 8 of the device unit 7 through the air supply duct 10 of the present invention described below. It passes through the inside and is exhausted to the back side of the housing 1 from the warm air discharge port 9. In addition, it is also possible to supply cold air from the back of a housing | casing and to discharge | emit from a front, and in this case, it is sufficient to replace the context of this embodiment.

  As shown in FIG. 4, the space between the left and right mount angles 4 on the front side of the housing and the side plate 5 is sealed by a shield plate 11 that blocks ventilation in the front and back 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 obtained by bending the end of the shield plate 11 at a right angle. Although a plurality of openings 12 are formed on the surface 11B of the shield plate 11 as shown in FIG. 3, these openings 12 can be shielded by the removable shielding member 13. The shield plate 11 is symmetrical.

  In the present embodiment, as shown in FIG. 3 and FIG. 4, the shielding member 13 is removed on the right side of the housing where the cold air intake port 8 of the device unit 7 is provided, so that cold air can be sucked from the front of the housing It has become. However, on the left side of the case 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 to the front side of the case.

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

  The instrument 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 the front and rear mount angles 4 and 4 to support the left and right end portions of the device unit 7. ing. The equipment unit support member 15 is L-shaped in 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 device unit 7 can be supported, when the earthquake or the like occurs when the sensor unit 7 is attached only to the mount angle 4, the load of the device unit concentrates on the mounting portion of the mount angle 4 Although the mount angle 4 may be deformed, the load on the device unit 7 can be supported by the device unit support member 15, so that the earthquake resistance can be improved. In addition, a sealing plate 19 to be described later is attached to the back side of the device unit 7 in the device unit support member 15, and a mounting position changing portion 22 is formed in which a plurality of mounting holes are formed to change the mounting position back and forth. 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 the cold air from leaking.

  Next, the air supply duct 10 of the present invention will be described. The air supply duct 10 is formed of a guide angle 18, a sealing plate 19, and a side plate 5.

And its tip end 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-angles 20 are provided in pairs 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 is provided so as to extend between the pair of upper and lower guide angles 18 formed on the back of the equipment unit 7. Attach 19 and seal the rear end. 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. The air supply duct 10 is formed only on the right side of the case where the cold air intake port 8 of the device unit 7 is located, and as shown in FIG. Intake and supply 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 housing. The sealing plate 19 may be directly attached to the device unit 7.

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 conventionally. In addition, the air supply duct 10 can be easily formed even if the device unit 7 or other communication device is attached to the mount angle 4 or the housing first.

  Since the L angle 20 described above 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 cold air from leaking 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 formed on the back of the device unit 7, but by forming the sealing plate 19 separately, the front and rear of the device unit 7 can be Even if the shape of the direction and the 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 according to the size of the device unit 7. It can also be fixed at a position according to the size of the.

  In the above embodiment, the sealing plate 19 is formed on the back surface of the device unit 7 so as to form a flow path of cold air toward the cold air intake port 8 of the device unit 7 through the opening 12 on the front side. Although there is a case, 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 end portions 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 flow path of warm air from the warm air discharge port 9 of the device unit 7 to the back of the housing. Since the sealing plate 19 is formed on the front surface of the device unit 7 of the warm air discharge port 9, it is possible to prevent cold air and warm air from being mixed and to form an air supply duct easily. A shield plate 11 is provided on the back of the housing so that the opening 12 on the cold air intake 8 side is covered with the shielding member 13 and warm air from the warm air discharge port 9 is transferred to the back of the housing through the opening 12.
