Description
本発明は、データセンター等において列状に配置されたラックの冷却効率を高めるために用いられるラックの片側空間閉塞装置に関するものである。 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.
データセンター等においては、サーバやその付属機器を搭載した多数のラックを列状に配置し、対向するラック列間の床面に設けられた冷気供給口からラック前面側に冷却空気を供給し、ラックの内部を通過させてラック背面側から排熱空気として排気する冷却システムが採用されている。この冷却システムにおいては、冷却効率を高めるために、互いのラック列の冷却空気を取り込む前面側を対向して配置した上、冷却空気と排熱空気とが混ざらないように、ラックの通路間を閉塞するような区画を形成することがある。そこで、例えば特許文献１に示されるように、対向するラック列間の通路の上部に遮蔽板を架け渡すことにより、通路内の空間を閉塞し、その上方空間と区画して空気の流動を規制している。 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 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. is doing.
このようにラック列間の通路に冷却空気と排熱空気とを区画するような閉塞空間を形成すれば、多数のラックを効率よく冷却することができ、またこの通路を利用して保守点検作業も行い易いという利点がある。 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.
ところが、実際には前述のようにラック前面側が対向して配置されるとは限らない。対向するラック列が存在しない端部のラック列の場合や、対向するラック列の長さが異なる場合、ラック列の前面側が互いに対向して配置されていない場合には、特許文献1のようにラック列間の通路に閉塞空間を形成することができない。そこで、対向するラックの有無に関わりなくラックの片側の空間を閉塞できる構造が求められているのであるが、通路の幅や床面の冷気供給口の配置に合わせた位置調整が可能でなければならない。また、冷却空気の風量に応じ、ラックの片側に形成される閉塞空間の大きさ（容量）も可変であることが望まれる。 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 Don't be. It is also desirable that the size (capacity) of the closed space formed on one side of the rack is variable according to the air volume of the cooling air.
閉塞空間の大きさを可変とするためには、ラックの天井部にスライド可能な天井パネルを設置することも考えられるが、ラックの天井面を覆ってしまうことでラックの天井面からのケーブルの引き込みの障害になるという問題があるうえ、ラック奥行き寸法が比較的短い場合には、天井パネルの長さがラックの奥行き寸法よりも長くなり、正面パネルをラックの奥行き方向に押し込むと、天井パネルの端部がラックの天井からはみ出してしまい、排熱空気の流動を妨げて熱溜りを形成するなどの問題もあった。しかし、これらの要求を満足できるものはこれまで提案されていない。 In order to make the size of the enclosed space variable, it is conceivable to install a slidable ceiling panel on the ceiling of the rack, but the cable from the ceiling of the rack is covered by covering the ceiling of the rack. If the rack depth dimension is relatively short, the ceiling panel length is longer than the rack depth dimension and the front panel is pushed into the rack depth direction. As a result, the end of the squeezed out from the ceiling of the rack, and the flow of exhaust heat air was hindered to form a heat reservoir. However, no one that can satisfy these requirements has been proposed.
従って本発明の目的は、対向するラック列の有無や配置状況に関わらず、その片側に閉塞空間を形成することができ、床面の冷気供給口の配置や通路幅などに対応させて位置調整が可能であり、閉塞空間の大きさが可変であり、しかもラックの天井面からのケーブルの引き込みにも支障がなく、熱溜りを発生させたりすることのないラックの片側空間閉塞装置を提供することである。 Accordingly, an object of the present invention is to form a closed space on one side regardless of the presence or arrangement of opposing rack rows, and to adjust the position according to the arrangement of the cold air supply port on the floor, the passage width, etc. A rack one-side space closing device that can change the size of the closed space, does not hinder cable drawing from the ceiling surface of the rack, and does not cause heat accumulation. That is.
上記の課題を解決するためになされた本発明は、ラック列の片側に冷却空気と排熱空気とを区画する閉塞空間を形成するために、各ラックの天井面と床面との間に設けられるラックの片側空間閉塞装置であって、一端がラックの天井面に支持された天井パネルと、この天井パネルの他端に連結された正面パネルとからなり、この天井パネルの奥行き寸法を可変としたことを特徴とするものである。 The present invention made to solve the above problems is provided between the ceiling surface and the floor surface of each rack in order to form a closed space for partitioning cooling air and exhaust heat air on one side of the rack row. 1 is a one-side space closing device for a rack, comprising a ceiling panel having one end supported by the ceiling surface of the rack and a front panel connected to the other end of the ceiling panel, the depth dimension of the ceiling panel being variable. It is characterized by that.
なお、天井パネルは複数のパネル部材から構成され、これらのパネル部材を重ね合わせることにより天井パネルの奥行き寸法を可変とすることが好ましい。また、伸長時における天井パネルの奥行き寸法が、ラックの天井面の奥行き寸法よりも長くなるような場合に用いることが好ましい。 The ceiling panel is preferably composed of a plurality of panel members, and the depth dimension of the ceiling panel is preferably made variable by overlapping these panel members. Moreover, it is preferable to use it when the depth dimension of the ceiling panel at the time of extension becomes longer than the depth dimension of the ceiling surface of the rack.
本発明のラックの片側空間閉塞装置は、一端がラックの天井面に支持された天井パネルと、この天井パネルの他端に連結された正面パネルとからなるものであり、これらのパネルによってラックの片側空間を閉塞し、冷却効率を高めることができる。また天井パネルの奥行き寸法を可変としたので、ラック天井面からの正面パネルの張出し位置を自由に変えることができ、通路幅などに対応させて片側空間を設定することができる。しかも天井パネルの奥行き寸法を可変としたことにより、ラックの天井面が天井パネルによって覆われる部分が少なくなり、ラックの天井面からのケーブルの引き込みにも支障がなくなるうえ、天井パネルの端部がラックの天井からはみ出して熱溜りを形成することも防止することができる。 The rack one-side space closing device of the present invention comprises a ceiling panel having one end supported on the ceiling surface of the rack and a front panel connected to the other end of the ceiling panel. One side space is obstruct | occluded and cooling efficiency can be improved. Further, since the depth dimension of the ceiling panel is variable, the position of the front panel overhanging from the rack ceiling surface can be freely changed, and the one-side space can be set according to the passage width and the like. In addition, since the depth dimension of the ceiling panel is made variable, the rack ceiling surface is less covered by the ceiling panel, and there is no hindrance to the cable drawing from the ceiling surface of the rack. It is also possible to prevent a heat reservoir from protruding from the ceiling of the rack.
以下に本発明の実施形態を説明する。
図１、図２はラック１の正面側に閉塞空間を形成した状態を示す斜視図である。図面では単一のラック１のみを示しているが、実際にはラック１は左右方向に密接配置されてラック列を構成し、以下に説明するラックの片側空間閉塞装置も左右方向に密接配置されて左右方向に連続する閉塞空間を形成するものである。また２は通路の床面であり、床下から供給される冷却空気の供給口が配設されている（不図示）。
Embodiments of the present invention will be described below.
1 and 2 are perspective views showing a state in which a closed space is formed on the front 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 side-closing device described below is also closely arranged in the left-right direction. Thus, a closed space continuous in the left-right 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).
本発明のラックの片側空間閉塞装置は、一端がラック１の天井面３に水平に支持された天井パネル４と、この天井パネル４の他端に連結された正面パネル５とからなるものである。天井パネル４はポリカーボネート樹脂等の透明板をアルミニウム等の金属製の枠部６で囲って形成されたもので、透明としたのは内部が暗くなることを防止するためである。 The rack one-side space closing device of the present invention comprises a ceiling panel 4 having one end horizontally supported by the ceiling surface 3 of the rack 1 and a front panel 5 connected to the other end of the ceiling panel 4. . The ceiling panel 4 is formed by surrounding a transparent plate made of polycarbonate resin or the like with a metal frame portion 6 such as aluminum, and is made transparent in order to prevent the inside from becoming dark.
この天井パネル４は複数枚に分割された構造であり、本実施形態では３枚のパネル部材４ａ〜４ｃに分割されている。図４以下に示すように、各パネル部材４ａ〜４ｃは側面および後面がコ字状となった枠部６ａ〜６ｃと、その内部にはめ込まれた透明板７ａ〜７ｃから構成され、入れ子構造となっている。すなわち、図示されるように基端側の第１のパネル部材４ａの内部に中間の第２のパネル部材４ｂが配置され、この第２のパネル部材４ｂの内部に、先端側の第３のパネル部材４ｃが配置されている。４ａ〜４ｃは、それぞれ所要の引き出し位置で枠部６に設けた固定ボルト１８により固定できるようになっている。 The ceiling panel 4 has a structure divided into a plurality of sheets, and is divided into three panel members 4a to 4c in the present embodiment. As shown in FIG. 4 and subsequent figures, each of the panel members 4a to 4c is composed of frame portions 6a to 6c whose side surfaces and rear surfaces are U-shaped, and transparent plates 7a to 7c fitted in the inside thereof. It has become. That is, as shown in the drawing, an intermediate second panel member 4b is disposed inside the first panel member 4a on the proximal end side, and the third panel on the distal end side is disposed inside the second panel member 4b. A member 4c is arranged. Each of 4a to 4c can be fixed by a fixing bolt 18 provided on the frame portion 6 at a required drawing position.
また図７に示されるように、第１のパネル部材４ａの先端と第２のパネル部材４ｂの先端には下向屈曲部８が形成され、第２のパネル部材４ｂと第３のパネル部材４ｃの基端には上向屈曲部９が形成され、相互間の脱落を防止している。また下向屈曲部８の内側にはパッキン１０が設けられ、冷気の漏れを防止している。このように、３枚のパネル部材４ａ〜４ｃは伸縮可能な入れ子構造となっている。３枚のパネル部材４ａ〜４ｃの奥行き寸法を揃えておけば、図３に示すように最小寸法に折り畳むことができる。また図４に示すように伸長させることもできる。このような折り畳み構造を採用することにより、最大伸長時における天井パネル４の奥行き寸法を、ラック１の天井面３の奥行き寸法よりも長くすることができる。 Further, as shown in FIG. 7, a downward bent portion 8 is formed at the tip of the first panel member 4a and the tip of the second panel member 4b, and the second panel member 4b and the third panel member 4c are formed. An upward bent portion 9 is formed at the base end of each of them to prevent them from falling off. A packing 10 is provided inside the downward bent portion 8 to prevent the leakage of cold air. Thus, the three panel members 4a to 4c have a telescopic nested structure. If the depth dimensions of the three panel members 4a to 4c are aligned, they can be folded to the minimum dimension as shown in FIG. It can also be extended as shown in FIG. By adopting such a folding structure, the depth dimension of the ceiling panel 4 at the maximum extension can be made longer than the depth dimension of the ceiling surface 3 of the rack 1.
第１のパネル部材４ａの基端側は、図８に示されるようにラック１の天井面３に取付けられた固定金具１１に制震部材１２を介して固定されている。制震部材１２は硬質ゴム板などの弾性材料からなり、固定金具１１にねじ止めされている。また第１のパネル部材４ａの基端が、制震部材１２の上半部にねじ止めされている。このように固定金具１１との間に制震部材１２を介在させることにより、地震震動によるラック１の変位量と、天井パネル４及び正面パネル５からなる閉塞装置との変位量の違いを吸収する制震機能を備えることができる。 As shown in FIG. 8, the base end side of the first panel member 4 a is fixed to a fixing bracket 11 attached to the ceiling surface 3 of the rack 1 via a vibration control member 12. The vibration control member 12 is made of an elastic material such as a hard rubber plate and is screwed to the fixing bracket 11. Further, the base end of the first panel member 4 a is screwed to the upper half portion of the vibration control member 12. Thus, by interposing the damping member 12 between the fixture 11, the difference between the displacement amount of the rack 1 due to the earthquake vibration and the displacement amount of the closing device composed of the ceiling panel 4 and the front panel 5 is absorbed. It can be equipped with a vibration control function.
図１などに示されるように、固定金具１１はラック１の端部に近い位置に設けておくことが好ましい。これによってラック１の天井面３が天井パネル４によって覆われる部分が少なくなり、ラック１の天井面３からのケーブルの引き込みにも支障がなくなる。 As shown in FIG. 1 and the like, the fixing bracket 11 is preferably provided at a position near the end of the rack 1. As a result, the portion where the ceiling surface 3 of the rack 1 is covered by the ceiling panel 4 is reduced, and there is no trouble in drawing the cable from the ceiling surface 3 of the rack 1.
第３のパネル部材４ｃの先端には、正面パネル５が接続されている。正面パネル５もポリカーボネート樹脂等の透明板をアルミニウム等の金属枠１３で囲って形成されたものである。この実施形態では正面パネル５は第３のパネル部材４ｃの先端に垂直下向きに取付けられているが、ヒンジ機構によって回動可能とするとともに、図９に示すように角度調節部材１４によって、天井パネル４に対する正面パネル５の角度を任意に設定できるようにすることもできる。なお図９の角度調節部材１４は、正面パネル５の上側コーナー部の円弧状板１５と、天井パネル４のコーナー部の三角板１６とを重ね合わせ、２本のボルト１７により止める構造である。正面パネル５の下端は床面２に達している。 A front panel 5 is connected to the tip of the third panel member 4c. The front panel 5 is also formed by surrounding a transparent plate such as polycarbonate resin with a metal frame 13 such as aluminum. In this embodiment, the front panel 5 is attached vertically downward to the tip of the third panel member 4c. However, the front panel 5 can be rotated by a hinge mechanism, and as shown in FIG. The angle of the front panel 5 with respect to 4 can be arbitrarily set. 9 has a structure in which the arcuate plate 15 at the upper corner portion of the front panel 5 and the triangular plate 16 at the corner portion of the ceiling panel 4 are overlapped and stopped by two bolts 17. The lower end of the front panel 5 reaches the floor surface 2.
図１に示すように、この実施形態においては、正面パネル５の下端にスライド可能な閉塞部材３０が設けられている。この閉塞部材３０は硬質ゴム板からなる遮蔽部材３１と、この遮蔽部材３１を正面パネル５の下端にスライド可能に取付けるスライド部材３２とからなる。スライド部材３２は正面パネル５の金属枠１３の裏側の縦溝にナットをスライド自在に挿入しボルトにより固定されるもので、ボルトを緩めることにより上下方向にスライド可能である。これにより正面パネル５の下端を通路２の床面に密着させることができる。なお、スライド部材３２の下端部にキャスター３３を取付けることができる。これにより正面パネル５の位置調整が容易になり、震動吸収効果も高めることができる。 As shown in FIG. 1, in this embodiment, a slidable closing member 30 is provided at the lower end of the front panel 5. The closing member 30 includes a shielding member 31 made of a hard rubber plate, and a sliding member 32 that slidably attaches the shielding member 31 to the lower end of the front panel 5. The slide member 32 is a member in which a nut is slidably inserted in a vertical groove on the back side of the metal frame 13 of the front panel 5 and is fixed by a bolt, and can be slid in the vertical direction by loosening the bolt. As a result, the lower end of the front panel 5 can be brought into close contact with the floor surface of the passage 2. A caster 33 can be attached to the lower end of the slide member 32. Thereby, the position adjustment of the front panel 5 becomes easy and the vibration absorption effect can be enhanced.
このように構成された本発明のラックの片側空間閉塞装置は、図１に示すように天井パネル４を伸長させてラック１からの突出量を大きくしたり、あるいは図３に示すように天井パネル４を折り畳んでラック１からの突出量を小さくしたりして使用することができる。このため、正面パネル５の下端位置を通路の幅や床面２の冷却空気の供給口の位置に対応させて自由に設定することができる。これによりラック列の片側に閉塞空間を形成することができるので、対向するラック列がない場合やラック列の前面側が互いに対向して配置されていない場合にも、冷却空気と排熱空気とが混ざることがなくなり、冷却効率を高めることが可能となる。 The rack one-side space closing device of the present invention configured as described above extends the ceiling panel 4 as shown in FIG. 1 to increase the amount of protrusion from the rack 1, or as shown in FIG. 4 can be folded and used by reducing the amount of protrusion from the rack 1. For this reason, the lower end position of the front panel 5 can be freely set corresponding to the width of the passage and the position of the cooling air supply port of the floor surface 2. As a result, a closed space can be formed on one side of the rack row, so that cooling air and exhaust heat air are generated even when there is no opposing rack row or when the front sides of the rack row are not arranged to face each other. Mixing is eliminated and the cooling efficiency can be increased.
また本発明のラックの片側空間閉塞装置は、天井パネル４の奥行き寸法を可変としたので、一時的に折り畳めばその前面で作業をしたり、前面にラックがあるような場合にその扉を開いたりする場合に正面パネル５が邪魔になることがない。またラックの奥行き寸法が短い場合であっても、ラック１の奥行き寸法以上の通路の幅の閉塞空間を形成することも可能である。しかも天井パネル４を大型化しても、ラック１の反対側に天井パネル４が突出することもなく、熱溜りが発生することがない。 In addition, since the rack one-side space closing device of the present invention has a variable depth dimension of the ceiling panel 4, if it is temporarily folded, the front panel can be operated or the door is opened when there is a rack on the front surface. The front panel 5 does not get in the way. Further, even when the depth dimension of the rack is short, it is possible to form a closed space having a passage width larger than the depth dimension of the rack 1. Moreover, even if the ceiling panel 4 is increased in size, the ceiling panel 4 does not protrude on the opposite side of the rack 1 and no heat accumulation occurs.
以上に説明した実施形態では、天井パネル４を複数のパネル部材４ａ〜４ｃから構成し、これらのパネル部材４ａ〜４ｃを重ね合わせることにより天井パネル４の奥行き寸法を可変とした。しかし図１０に示すように天井パネル４を複数のパネル部材４ｄ、４ｅから構成し、それらをヒンジ４０により接続することもできる。この場合には、ラック１の天井面３の左右両側にガイドレール４２を設け、下側のパネル部材４ｄ及び上側のパネル部材４ｅをこのガイドレール４２の上面に位置調節自在に固定できる構造としておく。 In the embodiment described above, the ceiling panel 4 is composed of a plurality of panel members 4a to 4c, and the depth dimension of the ceiling panel 4 is made variable by overlapping these panel members 4a to 4c. However, as shown in FIG. 10, the ceiling panel 4 may be composed of a plurality of panel members 4 d and 4 e and connected by a hinge 40. In this case, guide rails 42 are provided on both the left and right sides of the ceiling surface 3 of the rack 1 so that the lower panel member 4d and the upper panel member 4e can be fixed to the upper surface of the guide rail 42 so as to be adjustable in position. .
具体的には、ガイドレール４２の前端部に支持腕部４１を設けておき、パネル部材４ｄ、４ｅをボルト等の締結手段によって任意の位置で固定できるようにしておく。正面パネル５を手前側に引き出したい場合には、図１０に示すように、上側のパネル部材４ｅをパネル部材４ｄと同一平面となるように１８０度に開き、上側のパネル部材４ｅを支持腕部４１に固定し、下側のパネル部材４ｄをラック１の端面から完全に引き出す。このような構造とすれば、ラック１の奥行き寸法よりも大きく天井パネル４を引き出すことができるので、ラック１の奥行き寸法が短い横長のラックにも適用可能である。また、正面パネル５をラック１の奥行き方向に押し込む場合には、パネル部材４ｅを回転させてパネル部材４ｄと重ね合わせれば、ラック１の背面側の天井面より配線を引き込む場合においても障害となることはない。 Specifically, a support arm portion 41 is provided at the front end portion of the guide rail 42 so that the panel members 4d and 4e can be fixed at arbitrary positions by fastening means such as bolts. When it is desired to pull out the front panel 5 to the front side, as shown in FIG. 10, the upper panel member 4e is opened at 180 degrees so as to be flush with the panel member 4d, and the upper panel member 4e is supported by the support arm portion. 41, and the lower panel member 4d is completely pulled out from the end surface of the rack 1. With such a structure, the ceiling panel 4 can be pulled out larger than the depth dimension of the rack 1, so that it can also be applied to a horizontally long rack having a short depth dimension. Further, when the front panel 5 is pushed in the depth direction of the rack 1, if the panel member 4e is rotated and overlapped with the panel member 4d, it becomes an obstacle even when the wiring is drawn from the ceiling surface on the back side of the rack 1. There is nothing.
なお、上記実施形態の変形例として、天井パネルの枠部６をレール部材で構成し、パネル部材同士をスライド自在に接続したものとしてもよい。さらに、パネル部材４ｄからパネル部材４ｅを着脱自在として天井パネルの奥行き寸法を可変とする構造としてもよい。 As a modification of the above embodiment, the frame portion 6 of the ceiling panel may be configured by a rail member, and the panel members may be slidably connected. Further, the panel member 4e may be detachable from the panel member 4d so that the depth dimension of the ceiling panel is variable.
以上に説明したように、本発明のラックの片側空間閉塞装置によれば、ラック１の片側空間を閉塞し、冷却効率を高めることができる。また天井パネル４の奥行き寸法を可変としたので、ラック１の天井面３からの正面パネル５の張出し位置を自由に変えることができ、通路幅に対応させて片側空間を設定することができるうえ、ラック１の天井面３が天井パネル４によって覆われる部分が少ないため、ラック１の天井面３からのケーブルの引き込みにも支障がなくなり、また天井パネル４の端部がラック１の天井面３からはみ出して熱溜りを形成することもないなどの多くの利点がある。 As described above, according to the rack one-side space closing device of the present invention, the one-side space of the rack 1 can be blocked and the cooling efficiency can be improved. In addition, since the depth dimension of the ceiling panel 4 is variable, the position of the front panel 5 protruding from the ceiling surface 3 of the rack 1 can be freely changed, and a one-side space can be set corresponding to the passage width. Since there are few portions where the ceiling surface 3 of the rack 1 is covered by the ceiling panel 4, there is no hindrance to the cable drawing from the ceiling surface 3 of the rack 1, and the end of the ceiling panel 4 is the ceiling surface 3 of the rack 1. There are many advantages, such as no thermal spilling out.
