Description

  The present invention relates to a communication device, an electronic device, and other devices, particularly racks that contain devices that generate heat. Specifically, racks are arranged on both sides across a passage, and are introduced from the outside to cool the devices in the rack. The present invention relates to a rack system that can divide a rack installation space into a hot aisle and a cold aisle so that the cool air that is generated and the exhaust heat of the equipment released from the rack are not mixed.

Devices such as communication devices and electronic devices generate heat during operation. For this reason, a rack in which these devices are mounted widely employs a system in which a cooling fan is built in to discharge warm air to the outside and the like, and at the same time introduce cool air from below the floor or from the side.
In the case of such a cooling method, in order to prevent a situation in which the warm air discharged from the rack wraps around and mixes with the cool air introduced into the rack, a space only for the warm air discharged from the rack (hot aisle) A system has been proposed in which a cold space (cold aisle) introduced into a rack is separated.

  For example, in Patent Document 1, rack rows are arranged in parallel on both sides of a passage, a shielding plate is spanned between opposing racks across the passage to cover the upper portion of the passage, and cool air is passed from below the floor to the passage. A structure in which cold aisle and hot aisle are separated by a shielding plate by charging the cool air from the front of the rack facing the aisle into the rack and releasing the warm air heated by the equipment from the top and back of the rack. Is disclosed.

Japanese Patent No. 4209351

  However, the configuration of Patent Document 1 is troublesome because a fixing member must be attached to the top of each rack in order to fix the shielding plate. In addition, since both ends serving as the entrance and exit of the passage remain open, if a door or the like is provided to further reliably separate the cold aisle and the hot aisle, a separate frame member is required at the end of the passage. Was necessary.

  Therefore, in view of such problems, the present invention provides a rack system that does not require a fixing member for attaching a shielding plate to each rack and that can be provided with a door or the like at an entrance without requiring an additional member. The purpose is to do.

In order to solve the above-mentioned problems, the invention of claim 1 is directed to form a pair of rack rows by arranging rack rows in which a plurality of racks for storing devices are arranged in a row so as to face each other across a passage. A rack system in which a shielding plate is spanned between upper portions of the racks to close the upper portion of the passage, and the passage side space of the rack and the upper space of the rack are separated, and the rack row end portions on the left and right of the passage entrance In all four places, pillars having substantially the same height as the racks are erected, wires are placed between the upper parts of the pillars arranged at both ends of the rack row, and are arranged on both sides along the passage. A shield plate is spanned between the wires to cover the passage, while the individual racks constituting the rack row are placed on a pedestal arranged below the floor, and the lower part of the column is placed on the pedestal It is characterized by being connected and fixed to.
According to this configuration, since the shielding plate is supported by the wire spanned between the columns, it is not necessary to provide a fixing member for the shielding plate in each rack, and the shielding plate installation work is easy. Further, since the lower part of the support is fixed by being connected to the frame under the rack, it is not necessary to connect to the rack itself, and the mounting work is easy.

According to a second aspect of the present invention, in the configuration according to the first aspect, a door is hinged to the support column, and both ends serving as an entrance / exit of the passage can be closed by the door.
According to this structure, a door can be installed using a support | pillar, and the frame member for installing a door separately is unnecessary.

  According to the present invention, since the shielding plate is supported by the wire spanned between the columns, it is not necessary to provide a fixing member for the shielding plate in each rack, and the shielding plate installation work is easy. Further, since the lower part of the support is fixed by being connected to the frame under the rack, it is not necessary to connect to the rack itself, and the mounting work is easy. In addition, it is possible to easily provide doors that block both ends of the passage by using the columns.

In FIG. 2, reference numeral 4 denotes a rack installed under the rack 10 for each rack 10 in order to support the weight of the rack 10, 5 a wire for supporting the shielding plate 2, and 6 a support column for laying the wire 5. The plate 2 is attached to the wire 5 laid between the columns 6 and 6 erected at both ends of the rack row 1.

Here, the floor on which the rack 10 is installed will be described. The floor on which the rack 10 is installed is formed of a double floor. In FIG. 2, F1 indicates the position of the lower first floor, and F2 indicates the position of the upper second floor. Thus, the gantry 4 is formed at the same height as the second floor, and is installed on the first floor. The rack 10 is installed on the second floor on the gantry 4.
FIG. 1 shows a state in which the rack 10 is arranged on the second floor. At this time, since the gantry 4 is under the floor, it does not appear in appearance.

  The space between the first floor and the second floor, which is an underfloor space, is chilled air sent from an air conditioner that is separately installed for routing various cables and communication lines and cooling the equipment in the rack 10. Used as a ventilation space.

The column 6 is erected with the lower ends thereof connected to the gantry 4, 4 at both ends of the row arranged at the entrance / exit of the passage L among the gantry 4, 4,.
FIG. 3A shows an enlarged view of a portion A in FIG. 2, and FIG. 3B shows a state where the column 6 is attached. As shown in FIG. 3, the gantry 4 has a rectangular frame 4a having the same dimensions as the rack 10 and legs 4b provided at the four corners of the frame 4a. The legs 4b have a double floor. They are formed at the same surface forming height. The column 6 is erected by being screwed to the leg 4b on the passage L side of the gantry 4 with screws and nuts (not shown).

  Thus, the column 6 is installed at the front end of the rack 10 on both sides of the entrance and exit of the passage L, and the wire 5 is installed between the columns 6 and 6 installed at both ends of the rack row 1. The wire 5 is attached to both the rack rows 1 and 1, is installed in parallel on the passage L, and the shielding plate 2 is attached between the wires 5 and 5.

4A and 4B show a structure for attaching the wire 5 to the column 6, FIG. 4A is an exploded view, and FIG. 4B is an explanatory view of a connected state. As shown in FIG. 4, a connector 13 having a screw hole 13 a for screwing a bolt 12 is attached to the end of the wire 5. The connector 13 is formed in a cylindrical shape, and a screw hole 13 a is provided on the same axis as the wire 5.
On the other hand, a support fitting 14 that holds the bolt head portion through the threaded portion of the bolt 12 is provided at the top of the column 6. The support fitting 14 is formed in a substantially U shape, has a through hole 14a through which the screw portion of the bolt 12 is inserted in the central flat portion, and is provided with screw stopper pieces 14b for fixing to the support column 6 at both bent ends. It has been. After the wire 5 is connected to the support fitting 14 by the bolt 12, the tension of the wire 5 is adjusted by the screwing amount of the bolt 12 into the connector 13.
Note that the upper end of the support 6 is provided with a connecting piece (not shown) for screwing the support fitting 14, and the upper end of the support to which the wire 5 is attached is covered and protected by a cap 15 made of synthetic resin.

  FIG. 5 is an enlarged view of the shielding plate 2, (a) is a perspective view, and (b) is a side view. The shielding plate 2 is formed by a steel plate square frame 2a that forms an edge portion and a resin plate 2b that closes the inside of the frame 2a, thereby reducing the weight. As shown in FIG.5 (b), the edge part engaged with the wire 5 has the accommodating part 2c bent in the shape of U shape and opened | released toward the inner side, and the wire 5 can be easily attached or detached from diagonally downward inside. It is configured to be able to.

  The width of the shielding plate 2 is formed in accordance with the width of the rack 10, and the upper portion of the passage is well closed by installing the number of shielding plates 2 corresponding to the number of racks 10 connected. Further, the door 3 is hinged to both the support columns 6 and 6 installed on both sides of the passage L, and the entire width of the passage L can be opened by opening the doors.

  As a result, the entrance and exit and the ceiling of the passage L closed on both sides by the rack 10 are closed, and only the passage L is separated from the surrounding space. Therefore, the cool air is introduced into the passage L through the underfloor space, the cool air is sucked from the front of the rack 10 facing the passage L, and the warm air warmed by the mounted equipment is discharged from the back or upper portion of the rack 10. When the flow is formed, mixing of cold air and warm air can be prevented. That is, cold aisle and hot aisle can be clearly separated.

In this way, since the shielding plate 2 is supported by the wires 5 spanned between the columns 6 and 6, there is no need to attach a fixing member for the shielding plate 2 to each rack 10, and the shielding plate installation work is easy. is there. Further, the support column 6 is connected to the gantry 4 of the rack 10 and is not connected to the rack 10 itself, so that the mounting operation is easy, and a stable state can be maintained even if the tension of the wire 5 is applied.
Specifically, when connecting to the rack 10 itself rather than the gantry 4, it is screwed to an angle frame or the like erected at the four corners of the rack 10. In this case, it is screwed from within the rack 10. This is preferable and is a troublesome operation. Moreover, when connecting via the side plate of the rack 10, it becomes further troublesome. In that respect, since the screwing portion is concealed under the floor, the screwing to the gantry 4 is easy to work without any problem in terms of safety and appearance even if screwing from the support column 6 side which is outside.
Moreover, since the door 3 can be installed using the support | pillar 6, the frame member for the door 3 is not required separately.

In the above embodiment, the upper portion of the support 6 is a free end simply by attaching the wire 5, but a beam member may be bridged between the upper ends of the supports 6 and 6 arranged on both sides of the passage L. By spanning the beam member, the periphery of the door 3 can be made a more robust structure.
Further, the means for closing the entrance / exit of the passage L may not be the door 3 but may be closed by a flexible sheet such as a vinyl sheet as a simple partition. Thus, hot aisle and cold aisle can be separated only by providing a partition member.
