Description

  The present invention relates to a cabinet for storing electrical and electronic equipment suitable for installation in a server room such as a data center.

  In a server room such as a data center, a plurality of cabinets for storing electrical and electronic devices are connected and arranged, and unit-sized electrical and electronic devices are mounted on device mounting mounts inside the cabinets. In order to prevent an increase in internal temperature due to heat generated by these electric and electronic devices, a structure in which cold air is sucked from the front of the cabinet housing and exhausted from the rear is common. (Patent Document 1)

  In such a server room, in order to supply cool air to each cabinet, the cool air is led into the passage from the ceiling or under the floor of the front passage of the cabinet, and the heated air passes through the inside of the cabinet. A structure for collecting and discharging in a space called hot aisle on the back side is adopted.

  However, not all electrical and electronic devices are mounted inside the cabinet, and there may be a space portion without internal devices for future expansion. In such an unmounted portion, the cold air sucked from the front surface of the cabinet escapes to the back side as it is without being heated. Moreover, since the flow resistance inside the cabinet is small in the unmounted portion, a large amount of cool air flows out from the mounted portion, leading to a decrease in cooling efficiency.

  Therefore, conventionally, a blank panel or the like was attached to the cabinet in an unmounted part of the cabinet to prevent the flow of cool air. However, if there are many unmounted parts, it takes a lot of work to install the blank panel. When a new device is mounted on the mounting portion, the blank panel has to be removed, and there is a problem that these operations are complicated.

JP 2008-271665 A

  The present invention solves the above-described conventional problems, and can easily prevent the flow of cold air when there is an unmounted portion in the cabinet without requiring a large amount of work. It is an object of the present invention to provide a cabinet for storing electrical and electronic equipment that can easily cope with mounting of various devices.

  In order to solve the above problems, the present invention provides a ventilation shielding member that can be pulled out and wound on the upper, lower, or left and right sides of a cabinet case in which electrical and electronic equipment is mounted. This is characterized in that the portion can be shielded.

  In addition, it can be set as the structure which provided the ventilation shielding member in the position which shields the vent on the outer surface of a housing | casing, and shall be the structure which provided the ventilation shielding member in the position which shields the space part between the mounts inside a housing. Can do. Furthermore, the ventilation shielding member can be a roll screen, or a plurality of plate-like shielding members can be connected.

  Since the cabinet for storing electrical and electronic equipment according to the present invention is provided with ventilation shield members that can be drawn out and wound on the upper, lower, or left and right sides of the cabinet housing, the ventilation shielding member is pulled out from the winding state. Thus, the unmounted portion of the housing can be easily shielded. For this reason, the cool air does not escape from the unmounted portion to the hot aisle side, and the cooling efficiency can be improved.

  Further, when a new device is mounted on the unmounted portion, it is only necessary to wind up the ventilation shielding member, and in this case, no complicated work is required. In addition, since the ventilation shielding member is unnecessary for the cabinet without an unmounted part, it is preferable that the ventilation shielding member can be easily attached only to the necessary cabinet.

It is a perspective view which shows the state by which the electrical / electronic equipment storage cabinet was connectedly arranged in multiple rows. It is a perspective view of the cabinet for electrical and electronic equipment storage which attached the ventilation shielding member on the outer side. It is a perspective view of the cabinet for electrical and electronic equipment accommodation which attached the ventilation shielding member inside. It is a perspective view of the cabinet for electrical and electronic equipment accommodation which attached the ventilation shielding member inside.

Hereinafter, preferred embodiments of the present invention will be described.
FIG. 1 is a perspective view showing a state in which a plurality of rows of electrical and electronic equipment storage cabinets 1 are connected and arranged in a server room such as a data center. Here, in order to simplify the drawing, an arrangement of 3 × 2 rows is shown. Is shown. Two rows of electric and electronic equipment storage cabinets 1 are arranged with their front surfaces 2 facing each other, and a passage 3 is formed between them. The floor surface of the passage 3 is formed of a breathable material such as a lattice shape, and cold air is supplied upward from the floor into the passage 3. The cool air is sucked into the interior through the vent holes formed in the front surface 2 of the housing of each electrical / electronic equipment storage cabinet 1, and is discharged from the vent holes formed in the rear surface 4 of the housing after cooling the internal devices. The

  The electrical / electronic equipment storage cabinet 1A at the right end of the rear row has a normal structure because the electrical / electronic equipment is mounted in the entire interior of the housing, but the central electrical / electronic equipment storage cabinet 1B and the left-end electrical Since there is an unmounted portion inside the casing of the electronic device storage cabinet 1C, a ventilation shielding member 5 that can be pulled out and wound to shield the unmounted portion is attached to the front surface 2 of the casing. . In the central electrical / electronic equipment storage cabinet 1B, the upper half is an unmounted part, so the ventilation shielding member 5 is pulled out to the upper half, and in the leftmost electrical / electronic equipment storage cabinet 1C, the entire housing is not mounted. Since it is a part, the ventilation shielding member 5 is pulled out to the lower part of the housing.

  FIG. 2 is an enlarged view thereof, and a roll screen-shaped ventilation shielding member 5 is attached to the upper portion of the front surface 2 of the electrical / electronic equipment storage cabinet 1. Since the internal devices are usually mounted sequentially from the lower part of the casing, the ventilation shielding member 5 is attached to the upper part. However, when the internal equipment is mounted from the upper part, the ventilation shielding member 5 is attached to the lower part. The roll screen-shaped ventilation shielding member 5 has a structure in which a winding shaft is accommodated in a base portion 6 and a tip portion can be pulled out to an arbitrary position. However, a plurality of plate-like shielding members may be connected to enable winding. In the case of a rollable one, it is preferable to have a structure that can be rolled up by itself such as a roll screen. In addition, when setting it as a folding structure, the board | plate material of the unit height (unit height) of an internal apparatus can be used.

  As a means for attaching the ventilation shielding member 5, a magnet that can be attached with one touch is preferable, but it may be attached with a screw. Such a ventilation shielding member 5 may be attached to either the front surface 2 or the back surface 4 of the housing, but when attached to the front surface 2, it is preferably attached to the outside of the housing as described above, and is attached to the back surface 4. In some cases, it is preferable to attach the inside of the housing. This is because the ventilation shielding member 5 is easily adhered to the vent hole if attached in this way.

  A hook 7 is provided at the tip of the ventilation shielding member 5 so that it can be locked to the end of the cabinet 1 for storing electrical and electronic equipment. In the case of the roll screen-shaped ventilation shielding member 5, it is preferable to provide a hooking portion in the housing for each unit height of the internal device. In addition, when the outer wall of the housing is punched metal and vent holes are formed, it is possible to hook using the punched metal hole, in which case the hook position can be changed relatively freely. Can do.

  3 and 4 show an example in which the ventilation shielding member 5 is attached to the inside of the housing. In FIG. 3, since the internal device is mounted from the lower side, the unmounted portion above the ventilation shielding member 5 is mounted. In FIG. 4, since the internal device is not mounted, the entire surface is shielded by the ventilation shielding member 5. In this way, when the ventilation shielding member 5 is attached to the inside of the housing, it can be attached using the mount 8 at a position that shields the space between the mounts 8 and 8 inside the housing. Moreover, it is not always necessary to attach to the upper end of the housing, and it can be attached to a unit height portion of the internal device. In the case of the roll screen-shaped ventilation shielding member 5, it is preferable that the hooks at the tip thereof are formed on the mount 8 or the housing at intervals corresponding to the unit height of the internal device. However, it is also possible to use the device mounting hole array 9 formed in the mount 8.

  The ventilation shield member 5 is attached with a magnet or a suction cup as necessary to prevent fluttering due to airflow, preventing the airflow from passing from both sides of the ventilation shield member 5 and preventing a decrease in cooling efficiency. It is preferable to do. Alternatively, a guide member may be provided on both sides like a garage shutter to prevent airflow from passing through.

  Although any material such as cloth, paper, resin, or metal can be selected as the ventilation shielding member 5, practically, cloth, resin, metal foil or the like is appropriate in consideration of strength and ventilation blocking property. is there.

  The electrical and electronic equipment storage cabinet of the present invention configured as described above can easily shield the airflow flowing through the unmounted portion of the housing by the ventilation shielding member 5 without requiring a lot of work. For this reason, the cool air does not escape from the unmounted portion to the hot aisle side, and the cooling efficiency can be improved.
