Description

  The present invention relates to a rack one-side space 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 that exhausts exhaust heat air from the back side of the rack through the inside of the rack is employed. 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 opposite to each other, and the rack passages are not mixed so that the cooling air and the exhaust heat air are not mixed. A compartment may be formed that closes. 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 inspection work can be performed using this path. There is an advantage that it is easy to perform.

  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. Further, since the closed space is formed, it is necessary not to interfere with maintenance / inspection work in the path between the rack rows, opening / closing of the rack door, and carrying of the luggage. However, no one that can satisfy these requirements has been proposed.

  Embodiments of the present invention will be described below.

(First embodiment)
FIG. 1 is a perspective view showing a state in which a closed space is formed on the front side of a rack 1 in the first embodiment. Although only a single rack 1 is shown, in reality, the racks 1 are closely arranged in the left-right direction to form a rack row, and one-side space closing devices for racks described below are 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 one-side space closing device for a rack according to the present invention comprises a horizontal ceiling panel 5 and a front panel 6 connected to the other end of the ceiling panel 5. The ceiling panel 5 is supported on the guide frames 4 attached to both sides of the ceiling surface 3 of the rack 1 so as to be slidable in the depth direction of the rack by slide means described later.
The ceiling panel 5 is formed by surrounding a transparent plate made of polycarbonate resin or the like with an outer frame portion 7 such as aluminum. The reason why the ceiling panel 5 is made transparent is to prevent the inside from becoming dark. As shown in FIGS. 4 and 5, the outer frame portion 7 of the ceiling panel 5 is formed of a hollow frame member, and includes a lower groove portion 9 having an inverted U-shaped cross section inside.

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. 2 and 3, the guide frame 4 has a U-shaped cross section and is provided with an inward projecting piece 10 at the top. The projecting piece 10 is formed with a plurality of fixing portions 11 at a constant pitch in the depth direction. In this embodiment, the fixing portion 11 is a fixing hole, and the first restricting member 12 can be fixed to the upper surface of the fixing portion 11, and the mounting position can be changed as necessary. The fixing hole 10 may be a series of long holes extending in the depth direction of the rack 1.
In the present embodiment, the first restricting portion is composed of a roller that rotates about a vertical axis, and the first restricting portion 12 is provided on the left and right outer sides of the ceiling panel 5 as shown in FIGS. 4 and 5. It abuts against the side surface of the frame portion 7 from the inside, and restricts the movement of the ceiling panel 5 in the horizontal direction with the sliding operation.

  A support fitting 13 is attached to the front end of the guide frame 4 as shown in FIG. The support fitting 13 is composed of a rear vertical surface, an upper surface formed by bending a plate material in an inverted U shape, a front vertical surface 22 and a front horizontal leg portion 22a. The support arm 14 is screwed. A packing is provided on the upper portion of the support fitting 13 to close the gap.

  The second restricting member 15 can be fixed to the upper surface of the support arm portion 14. In the present embodiment, the second restricting portion 15 is engaged with the nut 16 held in the inverted U-shaped lower groove portion 9 formed inside the outer frame portion 7 of the ceiling panel 5, and the nut 16. As shown in FIGS. 4 and 5, the tightening screw 17 is fitted to the nut 16 to be fastened and fixed to fix the position of the ceiling panel 5. The outside of the nut 16 is covered with a resin member. During the slide operation, the slide can be smoothly performed by loosening the fastening screw 17. At the time of sliding, the nut 16 abuts the inside of the inverted U-shaped lower groove portion 9, so that the movement of the ceiling panel 4 in the horizontal direction with the sliding operation can be restricted. On the other hand, during normal installation, the tightening screw 17 is fastened and fixed to stably hold the ceiling panel.

The first restricting portion 12 and the second restricting portion 15 are moved back and forth by the slide means constituted by the first restricting portion 12, the second restricting portion 15, and the left and right outer frame portions 7 of the ceiling panel. The rack one-side space closing device is slidably held at four points on the left and right.
Thereby, the function of smoothly sliding the one-side space closing device of the rack and the function of stably holding the fixed one at the time of fixing coexist, and at the time of sliding, the first restriction provided by shifting in the width direction of the rack 1 is provided. By holding the outer frame portion 7 so that the portion 12 and the second restricting portion 15 are sandwiched, it is possible to effectively avoid rattling and enable stable and smooth slide movement, and in the path between the rack rows It does not hinder maintenance and inspection work, opening / closing of rack doors, and carrying goods.
In addition, the outer frame portion 7 of the ceiling panel 5 that is stably supported at the four points of front, rear, left and right even when fixed is arranged by shifting the respective positions in the width direction of the rack 1 by the pair of front and rear regulating portions. Therefore, even if a vibration occurs, it can be stably held.
Further, according to the configuration in which at least one of the restricting portions is held by the nut 16 and the fastening screw 17 held in the lower groove portion 9, the ceiling panel 5 can be slid or fixed by a simple operation as necessary. Therefore, the operability in the sliding work at the time of maintenance inspection can be improved.

  A front panel 6 is connected to the other end of the ceiling panel 5 so that the angle can be adjusted. Similarly to the ceiling panel 5, the front panel 6 is also formed by surrounding a transparent plate such as polycarbonate resin with an outer frame portion such as aluminum. An arc-shaped plate having two long holes is fixed to the upper corner portion of the front panel 6 as a first plate portion. In addition, a triangular plate 18 having two fixing holes corresponding to the long holes is fixed to the corner portion of the other end portion of the ceiling panel 5 as a second plate portion. If these arcuate plates and the triangular plate 18 are overlapped and fixed with bolts inserted into both holes, the angle of the front panel 6 with respect to the ceiling panel 5 can be adjusted within the range of the long holes. The reason why the angle of the front panel 6 is made variable is to adjust the lower end position of the front panel 6 in correspondence with the cooling air supply port of the floor 2.

  As shown in FIG. 1, in this embodiment, a slidable closing member is provided at the lower end of the front panel 6. The closing member includes a shielding member 19 made of a hard rubber plate, and a slide member 20 that slidably attaches the shielding member 19 to the lower end of the front panel 6. The slide member 20 is a member in which a nut is slidably inserted into a vertical groove on the back side of the metal frame of the front panel 4 and is fixed by a bolt, and can be slid in the vertical direction by loosening the bolt. The shielding member 19 is fixed to the slide member 20. The caster 21 can be attached to the lower end portion of the slide member 20. As a result, the lower end of the front panel 6 can be brought into close contact with the floor surface of the passage 2.
