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を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 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 from each other's rack rows are arranged facing each other, and the space between the rack passages is blocked so that the cooling air and exhaust heat air are not mixed Such a compartment may be formed. 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、ラックの片側の閉塞空間より冷却空気が流出しないようにする必要がある。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。 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. Further, it is necessary to prevent the cooling air from flowing out from the closed space on one side of the rack. 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、しかも床面の冷気供給口の配置や通路幅に対応させて位置調整が可能であり、位置調整の際にラックの片側の閉塞空間より冷却空気が流出することを防ぐことが可能なラックの片側空間閉塞装置を提供することである。 Therefore, the 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 and the passage width. It is possible to provide a rack one-side space closing device capable of preventing cooling air from flowing out of the one-side closed space of the rack during position adjustment.
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る水平な天井パネルと、この天井パネルの他端に角度調整可能に連結された正面パネルとからなり、この正面パネルの下端と床面との距離を調整可能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 horizontal 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 so that the angle can be adjusted. The distance between the lower end of the floor and the floor surface is adjustable.
また、天井パネルと正面パネルとは、一方のパネルに固定され２つの長穴を備えた第１の板部と、他方のパネルに固定され前記２つの長穴に対応する固定穴を備えた第２の板部と、双方の穴に挿通するボルトとにより構成される角度調整機構により角度調整可能に連結されることが好ましい。 The ceiling panel and the front panel include a first plate portion fixed to one panel and having two long holes, and a first plate portion fixed to the other panel and having fixing holes corresponding to the two long holes. It is preferable that the angle adjustment mechanism configured by the two plate portions and the bolts inserted into both holes is coupled so as to be adjustable in angle.
なお、正面パネルの下端に、正面パネルに対してスライド可能な閉塞部材を設けた構造とすることが好ましい。 In addition, it is preferable to set it as the structure which provided the closure member which can be slid with respect to a front panel in the lower end of a front panel.
本発明のラックの片側空間閉塞装置は、水平な天井パネルと、この天井パネルの他端に角度調整可能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。また正面パネルは角度調節可能であるから、その下端位置を床面の冷気供給口に対応させて調整することができ、この正面パネルの下端と床面との距離を調整可能とすることにより、位置調整の際にラックの片側の閉塞空間より冷却空気の漏れを防止することができる。 The rack one-side space closing device of the present invention comprises a horizontal ceiling panel and a front panel connected to the other end of the ceiling panel so that the angle can be adjusted, and these panels close the one-side space of the rack. In addition, the cooling efficiency can be increased. In addition, since the front panel can be adjusted in angle, its lower end position can be adjusted to correspond to the cold air supply port on the floor surface, and by making the distance between the lower end of this front panel and the floor surface adjustable, When the position is adjusted, the cooling air can be prevented from leaking from the closed space on one side of the rack.
また請求項２のように天井パネルと正面パネルとは、一方のパネルに固定され２つの長穴を備えた第１の板部と、他方のパネルに固定され長穴に対応する２つの固定穴を備えた第２の板部と、双方の穴に挿通するボルトとにより構成される角度調整機構により角度調整可能に連結としておけば、床面の冷却空気の供給口に対応させて正面パネルの下端位置を容易に変更できる。 Further, as in claim 2, the ceiling panel and the front panel are: a first plate portion fixed to one panel and having two long holes; and two fixing holes corresponding to the long holes fixed to the other panel. If the angle adjustment mechanism composed of the second plate portion provided with a bolt inserted into both holes is connected so that the angle can be adjusted, the front panel panel can be connected to the cooling air supply port on the floor surface. The lower end position can be easily changed.
さらに請求項３のように正面パネルの下端にスライド可能な閉塞部材を設けた構造としておけば、正面パネルの傾斜角度を変えた場合にも常に正面パネルの下端を床面に密着させることができ、冷却空気の漏れを防止することができる。 Furthermore, if the structure is provided with a slidable closing member at the lower end of the front panel as in claim 3, the lower end of the front panel can always be brought into close contact with the floor even when the inclination angle of the front panel is changed. Cooling air leakage can be prevented.
以下に本発明の実施形態を説明する。
図１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.
FIG. 1 is a perspective view 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、水平な天井パネル３と、正面パネル４とからなる。天井パネル３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枠５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。図２に示すように、ラック１の天井面６には断面が逆Ｕ字状の固定金具７が取付けられており、金属枠５の一端をこの固定金具７に載せたうえ、金属枠５と固定金具７とをゴム板等からなる制震部材８を介して固定してある。この制震部材８は地震波に対するラック１と片側空間閉塞装置との変位量の違いを吸収するための部材である。このようにして天井パネル３の一端がラック１の天井面６に支持される。この実施形態では天井パネル３を制震部材８を介してラック１の天井面６に固定したのであるが、ラック１の天井面にスライド可能に支持させることも可能である。 The rack one-side space closing device of the present invention comprises a horizontal ceiling panel 3 and a front panel 4. The ceiling panel 3 is formed by surrounding a transparent plate made of polycarbonate resin or the like with a metal frame 5 such as aluminum. The reason why the ceiling panel 3 is made transparent is to prevent the interior from becoming dark. As shown in FIG. 2, a fixing bracket 7 having an inverted U-shaped cross section is attached to the ceiling surface 6 of the rack 1. One end of the metal frame 5 is placed on the fixing bracket 7, and the metal frame 5 The fixing bracket 7 is fixed via a vibration control member 8 made of a rubber plate or the like. This damping member 8 is a member for absorbing the difference in displacement between the rack 1 and the one-side space closing device with respect to the seismic wave. In this way, one end of the ceiling panel 3 is supported on the ceiling surface 6 of the rack 1. In this embodiment, the ceiling panel 3 is fixed to the ceiling surface 6 of the rack 1 via the vibration control member 8. However, the ceiling panel 3 can be slidably supported on the ceiling surface of the rack 1.
天井パネル３の他端には、正面パネル４が角度調整可能なヒンジによって連結されている。正面パネル４も天井パネル３と同様に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９で囲って形成されたものである。図３に示すように正面パネル４の上側コーナー部には第１の板部として２つの長穴１０、１１を備えた円弧状板１２が固定されている。また天井パネル３の他端部のコーナー部には、第２の板部として前記長穴に対応する２つの固定穴１７、１８を備えた三角板１３が固定されている。図４に示すようにこれらの円弧状板１２と三角板１３とを重ね合わせて双方の穴に挿通させたボルト１４、１５により止める。この角度調整機構により、天井パネル３に対する正面パネル４の角度を長穴１０、１１の範囲で調整しその角度を保持することができる。なお平板１３の端部は屈曲させ、正面パネル４の内側に当接させて角度規制部１６とすることが好ましい。このように正面パネル４の角度を可変としたのは、床面２の冷却空気の供給口に対応させて正面パネル４の下端位置を変更できるようにするためである。 The front panel 4 is connected to the other end of the ceiling panel 3 by a hinge whose angle can be adjusted. Similarly to the ceiling panel 3, the front panel 4 is formed by surrounding a transparent plate such as polycarbonate resin with a metal frame 9 such as aluminum. As shown in FIG. 3, an arcuate plate 12 having two long holes 10 and 11 is fixed to the upper corner portion of the front panel 4 as a first plate portion. Further, a triangular plate 13 having two fixing holes 17 and 18 corresponding to the elongated holes is fixed as a second plate portion at a corner portion of the other end portion of the ceiling panel 3. As shown in FIG. 4, these arcuate plate 12 and triangular plate 13 are overlapped and stopped by bolts 14 and 15 inserted through both holes. By this angle adjustment mechanism, the angle of the front panel 4 with respect to the ceiling panel 3 can be adjusted in the range of the long holes 10 and 11 and the angle can be maintained. The end of the flat plate 13 is preferably bent and brought into contact with the inside of the front panel 4 to form the angle restricting portion 16. The reason why the angle of the front panel 4 is made variable is that the lower end position of the front panel 4 can be changed in correspondence with the cooling air supply port of the floor surface 2.
図５〜図７に示すように、正面パネル４の下端にはスライド可能な閉塞部材２０が設けられている。この閉塞部材２０は硬質ゴム板からなる遮蔽部材２１と、この遮蔽部材２１を正面パネル４の下端にスライド可能に取付けるスライド部材２２とからなる。スライド部材２２は図７に示されるように正面パネル４の金属枠９の裏側の縦溝２３にナットをスライド自在に挿入しボルト２４により固定されるもので、ボルト２４を緩めることにより金属枠９に対して上下方向にスライド可能である。閉塞部材２０はスライド部材に固定されている。なお、スライド部材２２の下端部にキャスター２５を取付けることができる。 As shown in FIGS. 5 to 7, a slidable closing member 20 is provided at the lower end of the front panel 4. The closing member 20 includes a shielding member 21 made of a hard rubber plate and a slide member 22 that slidably attaches the shielding member 21 to the lower end of the front panel 4. As shown in FIG. 7, the slide member 22 is a member in which a nut is slidably inserted into a vertical groove 23 on the back side of the metal frame 9 of the front panel 4 and is fixed by a bolt 24. Can slide in the vertical direction. The closing member 20 is fixed to the slide member. A caster 25 can be attached to the lower end of the slide member 22.
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８に示すように正面パネル４を垂直にして使用することもでき、図９に示すように正面パネル４を傾斜させて使用することもできる。これにより通路の幅や床面２の冷却空気の供給口の位置に自由に対応させることができる。傾斜角度の調整は、ボルト１４、１５によって行うことができ、正面パネル４を傾斜させ、スライド部材２２を先端側にスライドさせて閉塞部材２０が床面２から離れないようにし、冷却空気の漏れを防止する。 The one-side space closing device for a rack of the present invention configured as described above can be used with the front panel 4 being vertical as shown in FIG. 8, and is used with the front panel 4 being inclined as shown in FIG. You can also Thereby, it is possible to freely correspond to the width of the passage and the position of the cooling air supply port of the floor surface 2. The inclination angle can be adjusted by the bolts 14 and 15, the front panel 4 is inclined, the slide member 22 is slid to the front end side so that the closing member 20 is not separated from the floor surface 2, and cooling air leaks. To prevent.
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存在しないような場合にも、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。また天井パネル３はラック１の天井面６の上方に充分な長さを有して水平に保持されているので、ラック１の扉を開閉するなどの保守点検作業をおこなう際の障害となることはない。
また、ラックの前面側が互いに対向して配置されていない場合、すなわち一方のラックの前面側と他方のラックの背面側が対向して配置されている場合には、一方のラックの正面パネル４に角度をつけることで、対向するラックの背面側からの排熱空気を排出するための空間を確保することができる上、排熱空気を上方に導くためのガイドとしても機能するものである。
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 not mixed even when there is no opposite rack row, and cooling efficiency can be improved. It becomes. Further, since the ceiling panel 3 has a sufficient length above the ceiling surface 6 of the rack 1 and is held horizontally, it becomes an obstacle when performing maintenance inspection such as opening and closing the door of the rack 1. There is no.
In addition, when the front sides of the racks are not arranged to face each other, that is, when the front side of one rack and the back side of the other rack are arranged to face each other, the front panel 4 of one rack is angled. By attaching, it is possible to secure a space for exhausting the exhaust heat air from the back side of the opposite rack, and also function as a guide for guiding the exhaust heat air upward.
なお、上記の実施形態では正面パネル４の下端に閉塞部材２０をスライド可能に取付けたが、正面パネル４の全体をスライド構造として伸縮させることもできる。同様に閉塞部材２０の全体をスライド構造として伸縮可能としてもよい。 In the above embodiment, the closing member 20 is slidably attached to the lower end of the front panel 4, but the entire front panel 4 can be expanded and contracted as a slide structure. Similarly, the entire closing member 20 may be extended and contracted as a slide structure.
