Description

  The present invention relates to a rack passage closing device used to increase the cooling efficiency of racks arranged in a line in a data center or the like.

  In data centers, etc., a large number of racks equipped with servers and their accessories are arranged in a row, and cooling air is supplied to the front side of the racks from the cold air supply port provided on the floor between the opposing rack rows. A cooling system is adopted that passes through the inside of the rack and exhausts it as exhaust heat air from the back side of the rack. In this cooling system, in order to increase the cooling efficiency, the front sides that take in the cooling air of the rack rows are arranged facing each other, and the cooling air and the exhaust heat air are not mixed between the passages of the rack rows. A compartment may be formed so as to occlude. Therefore, for example, as disclosed in Patent Document 1, a shield plate is placed over the passages between the opposing rack rows to close the space in the passages and partition the upper space to restrict the flow of air. doing.

  In this way, if a closed space that partitions cooling air and exhaust heat air is formed in the path between the rack rows, a large number of racks can be cooled efficiently, and maintenance inspections can be performed using this path. There is an advantage that it is easy to work.

  However, in practice, the front side of the rack is not necessarily arranged so as to face as described above. In the case of an end rack row where there is no facing rack row, the length of the facing rack row is different, or when the front sides of the rack row are not arranged facing each other, as in Patent Document 1 A closed space cannot be formed in the path between the rack rows. Therefore, there is a need for a structure that can close the space on one side of the rack regardless of the presence or absence of the opposing rack, but if the position cannot be adjusted according to the width of the passage and the arrangement of the cold air supply ports on the floor surface Don't be. It is also desirable that the size (capacity) of the closed space formed on one side of the rack can be adjusted according to the air volume of the cooling air.

On the other hand, when an earthquake or the like occurs, the rack having a relatively high height and heavy equipment inside may be displaced greatly with respect to the floor surface. Therefore, the member constituting the closed space in the path between one rack side or the opposite rack row moves so as to correspond to the displacement of the rack even after the position adjustment described above, and It is preferable that the structure prevents damage.
However, no one that can satisfy these requirements has been proposed.

The first embodiment of the present invention will be described below.
FIG. 1 is a perspective view showing a state in which a closed space is formed on one side of the rack 1. Although only a single rack 1 is shown in the drawing, the racks 1 are actually closely arranged in the left-right direction to form a rack row, and a rack passage closing device described below is also closely arranged in the left-right direction. A closed space continuous in the direction is formed. Reference numeral 2 denotes a floor surface of the passage, which is provided with a supply port for cooling air supplied from under the floor (not shown).

  The rack passage closing device of the present invention comprises a guide frame 4 attached to both sides of the ceiling surface 3 of the rack 1, a horizontal ceiling panel 5, and a front panel 6 connected to the other end of the ceiling panel 5. Is. The ceiling panel 5 is formed by surrounding a transparent plate made of polycarbonate resin or the like with a metal frame 7 such as aluminum. The reason why the ceiling panel 5 is made transparent is to prevent the interior from becoming dark.

Guide frames 4 extending in the depth direction are provided on the left and right sides of the ceiling surface of the rack 1. As shown in FIGS. 3 and 4, the guide frame 4 has a U-shaped cross section and is provided with an inward projecting piece 9 on the top. A plurality of fixing portions 10 are formed on the projecting piece 9 at a constant pitch in the depth direction. In this embodiment, the fixing portion 10 is a fixing hole, and the fixing hole 18 of the fixing bracket 11 shown in FIG. 5 can be screwed to the upper surface thereof. With such a structure, the mounting position of the fixing bracket 11 with respect to the guide frame 4 can be changed stepwise in the depth direction of the rack 1.
In addition, if the fixing hole 10 is a series of long holes extending in the depth direction of the rack 1, the degree of freedom of the mounting position of the fixing bracket 11 can be increased.

  As shown in FIG. 5, the fixing bracket 11 includes a rear vertical surface 12, an inverted U-shaped upper surface 13, and a front horizontal leg portion 14, and protrudes upward from the rear vertical surface 12. A single damping member 15 is screwed. The damping member 15 is made of a hard rubber plate or the like. Further, horizontal notches 16 are formed at the left and right ends of the rear vertical surface 12. As shown in FIGS. 3 and 4, the inwardly protruding pieces 9 of the guide frame 4 are fitted into these notches 16 to serve as guides when the fixing bracket 11 is slid in the depth direction. That is, the ceiling panel 5 connected to the fixing bracket 11 is not displaced from the left and right when the mounting position of the fixing bracket 11 is changed. The support leg 17 formed at the tip of the rear vertical surface 12 is in contact with the ceiling surface 3 of the rack 1 and holds the fixing bracket 11 stably.

As shown in FIG. 10, the slide member 32 is a member in which a nut is slidably inserted into a vertical groove 33 on the back side of the metal frame 8 of the front panel 6 and is fixed by a bolt, and can be slid in the vertical direction by loosening the bolt. It is. A caster 34 can be attached to the lower end of the slide member 32. Thereby, the lower end of the front panel 6 can be brought into close contact with the floor surface of the passage 2 and the rack passage closing device can be easily moved.

  The rack passage closing device of the present invention configured as described above increases the protruding amount of the ceiling panel 5 from the rack 1 as shown in FIG. 1, or the ceiling panel 5 from the rack 1 as shown in FIG. It can be used with a small protrusion amount. For this reason, even if it does not create the ceiling panel 5 from which a magnitude | size differs, the lower end position of the front panel 6 can be freely set according to the width | variety of a channel | path, or arrangement | positioning of the cooling air supply port of the floor surface 2. FIG. As a result, a closed space can be formed on one side of the rack row, so even in the case of an end rack row where there is no opposite rack row, or when the front sides of the rack row are not arranged facing each other, A closed space that partitions cooling air and exhaust heat air can be formed, and cooling efficiency can be improved. Since the ceiling panel 5 is held horizontally above the ceiling surface 3 of the rack 1, it does not become an obstacle when opening and closing the door of the rack 1.

Next, a second embodiment of the present invention will be described.
