3. Features of the rack according to the present embodiment The rack 3 according to the present embodiment includes a ventilation duct 33 protruding into the storage space 31A from a ventilation port 32A provided in the door portion 32. Thus, in the rack 3, the mixture of the intake air and the exhaust gas is suppressed by the ventilation duct 33.

  And since the ventilation duct 33 is provided in the door part 32, when the door part 32 is opened and the working opening 31F is opened, the ventilation duct 33 will be in a state of disappearing from the working opening 31F. Therefore, even in a configuration in which the ventilation duct 33 protruding toward the ICT device is provided, it is possible to suppress a decrease in the maintainability of the ICT device.

  The door portion 32 has a frame-shaped door body 32B provided with an opening 32C larger than the vent 32A, and blank panels 32D to 32G that form the vent 32A in the door 32 by closing a part of the opening 32C. Is configured.

  This allows the builder to easily change the position or size of the vent 32A according to the size of the ICT device 1 or the mounting position of the ICT device 1. In other words, the builder can obtain the ventilation holes 32A adapted to various ICT devices by changing the position or size of the blank panels 32D to 32G to be closed according to the ICT devices.

  The door main body 32B is provided with mounting portions 32H and 32J to which the first blank panels 32D and 32E can be removably mounted. Thereby, the installer can easily attach the first blank panels 32D and 32E to the door 32.

  Since the door portion 32 of the present embodiment is closed by the blank panels 32D to 32G at portions other than the ventilation holes 32A, the risk of stick-like foreign matter being thrust into the ICT device 1 from outside the rack 3 is reduced. obtain.

  The ICT device 1 is fixed in the rack 3 with the cold air passage (cold aisle) 3A side as a reference plane. Therefore, if the ventilation duct 33 is arranged on the front side of the storage space 31A, the following advantages can be obtained.

  (1) It is desirable that the number of the ventilation ducts 33 and the number of the ventilation holes 32A be the same as the number of the ICT devices 1. When a plurality of ICT devices 1 are mounted in the rack 3, the distance from the inner wall surface of the closed door portion 32 to each ICT device 1 is substantially the same.

  Therefore, when the ventilation duct 33 is arranged on the front side of the storage space 31A, the protrusion dimensions of the plurality of ventilation ducts 33 are substantially the same. Therefore, the workability of the installer is improved.

  Note that it is desirable that the gap dimension generated between the tip of the ventilation duct 33 and the ICT device 1 be as small as possible. Therefore, a configuration in which an elastically deformable member such as sponge or rubber is disposed between the tip of the ventilation duct 33 and the ICT device 1 may be used.

  (2) Since each ICT device 1 is fixed with reference to the reference surface side, the distance from the vent 32A to (the suction surface of) the ICT device 1 is short. Therefore, since the projecting dimension of the ventilation duct 33 is reduced, it is possible to prevent the ventilation duct 33 from becoming an obstacle and reducing the workability when the working opening 31F is opened.

(2nd Embodiment)
The door 32 and the working opening 31F according to the above-described embodiment were configured to be provided on the front side of the rack 3 (storage space 31A). On the other hand, the rack 3 according to the present embodiment has a configuration in which a door 35 is provided in a work opening 31G provided on the back surface of the rack 3 as shown in FIG.

  The configuration of the door 35 is the same as that of the door 32. That is, the door portion 35 is provided with the ventilation port 35A and the ventilation duct 33. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals as in the above-described embodiment. For this reason, in the present embodiment, duplicate description is omitted.

  Therefore, the ventilation duct 33 according to the present embodiment guides the hot air discharged from the ICT device 1 to the ventilation port 35A. Thereby, the mixture of the exhaust and the intake is suppressed by the ventilation duct 33.

  Note that it is desirable that the gap dimension generated between the tip of the ventilation duct 33 and the ICT device 1 be as small as possible. Therefore, a configuration in which an elastically deformable member such as sponge or rubber is disposed between the tip of the ventilation duct 33 and the ICT device 1 may be used.

  Incidentally, the allowable range of the gap dimension generated between the tip of the ventilation duct 33 and the ICT device 1 in the present embodiment is the gap dimension generated between the tip of the ventilation duct 33 and the ICT device 1 in the first embodiment. Is larger than the allowable range.

  Incidentally, the ICT device 1 is usually mounted in the storage space 31A such that the exhaust surface of the ICT device 1 is located on the back side. Then, usually, the exhaust gas is blown from the ICT device 1 in a jet state. For this reason, if the ventilation duct 33 is arranged on the back side of the storage space 31A, the following advantages can be obtained.

(1) The position of the exhaust port of the ICT device 1 is easily specified, and the installer can easily understand the installation position and the required size of the ventilation duct 33.
(2) Since the exhaust is in the form of a jet, recirculation of the exhaust is unlikely to occur in the rack 3 even if the ventilation duct 33 is not closely attached to the exhaust port of the ICT device 1.

  (3) Since the flow velocity of the exhaust jet is relatively large, even when the opening area of the ventilation duct 33 is larger than the exhaust port, the exhaust gas generally passes through the ventilation duct 33 and exits the rack 3 from the ventilation port 32A. Is discharged.

  (4) Since the exhaust gas discharged from the ICT device 1 is guided to the outside of the rack 3 without greatly decreasing the flow velocity by flowing through the ventilation duct 33, the door has a large mesh opening. In comparison, exhaust gas is less likely to be recirculated when passing through the door.

  (5) Since the cables are routed on the back surface, the exhaust gas may hit the cables and recirculate the exhaust gas. However, since the exhaust gas flows through the ventilation duct 33 and reaches the ventilation port 35A, a clear airflow path can be secured, and recirculation of the exhaust gas is suppressed.

(Third embodiment)
