Description

本発明は、電気電子機器収納用キャビネットの内部に搭載した電気・電子機器ユニットを効率よく冷却する電気電子機器収納用キャビネットの冷却構造に関するものである。     The present invention relates to a cooling structure for an electrical / electronic equipment storage cabinet that efficiently cools an electrical / electronic equipment unit mounted inside the electrical / electronic equipment storage cabinet.

従来の電気電子機器収納用キャビネット内に搭載した電気・電子機器ユニットを冷却するものとしては、冷却空気をキャビネットの床下に設けたダクト等より導入して二重壁構造の前扉内で上方に向け吹き上げて、前扉の内壁に上下に配設した空気流出開口から電気・電子機器ユニットの前面に供給するものが知れている（例えば、特許文献１参照）。   For cooling the electrical / electronic equipment unit mounted in the conventional cabinet for storing electrical and electronic equipment, the cooling air is introduced from the duct etc. provided under the floor of the cabinet. It is known that the air is blown upward and supplied to the front surface of the electric / electronic device unit through an air outflow opening disposed on the inner wall of the front door.

このような冷却構造は、冷却空気を下方から上方に向け吹き上げるためのファンやファンニット等をキャビネットの下部に設けておくだけでよく、簡単な構造で冷却空気を供給できる利点がある。しかし、これは吹き上げられ冷却空気は上方に達するに従い風速が強くなり、上方に設置したサーバ等の電気・電子機器ユニットは下方に設置したものに比べ冷却空気を十分に供給できない場合もあるため冷えにくく、キャビネットに上下に渡って搭載したサーバ等が均一に冷却されないという問題がある。   Such a cooling structure has an advantage that the cooling air can be supplied with a simple structure by simply providing a fan, a fan knit or the like for blowing the cooling air upward from below at the lower part of the cabinet. However, as the cooling air blows up and winds upward, the wind speed increases, and the server and other electrical / electronic equipment units installed above may not be able to supply cooling air sufficiently compared to those installed below. There is a problem that a server or the like mounted on the cabinet is not cooled uniformly.

前記のような問題を解消するものとして、電気電子機器収納用キャビネットの横に冷却装置を配置して、この冷却装置の横方向から冷却空気をキャビネットの前面に上部から下部に亘り均一に供給するものがある（例えば、特許文献２参照）。ところが、これは１台の冷却装置を２台の電気電子機器収納用キャビネットの間に設置して２台のキャビネットを冷却できるものとしても、データセンター等で多数の電気電子機器収納用キャビネットを連結した場合には、冷却装置の分だけ幅が広くなり、その幅分に応じた電気電子機器収納用キャビネットを削減しなければならないという問題がある。
特開２００３−０６１２１６公報 特表２００７−５２２５６９公報 In order to solve the above problems, a cooling device is arranged beside the cabinet for storing electrical and electronic equipment, and cooling air is uniformly supplied from the lateral direction of the cooling device to the front of the cabinet from the top to the bottom. There are some (see, for example, Patent Document 2). However, even if one cooling device can be installed between two electrical and electronic equipment storage cabinets to cool the two cabinets, many electrical and electronic equipment storage cabinets can be connected in a data center or the like. In this case, there is a problem that the width becomes wider by the cooling device, and the number of cabinets for storing electrical and electronic equipment corresponding to the width must be reduced.

次に、本発明の好ましい実施の形態を図面に基づき説明する。
１は電気電子機器収納用キャビネットである。この電気電子機器収納用キャビネット１は２つの四角状フレーム１０ａ、１０ａを前後に配置してその上下の四隅を４本の幅広の奥行きフレーム１０ｂで連結してなる直方体状の枠フレーム１０の両側面を側板１１で上下面を天板と底板で覆い前面と後面に扉２、３を設けてなるものである。 Next, preferred embodiments of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes an electric / electronic equipment storage cabinet. This electrical / electronic equipment storage cabinet 1 has two rectangular frames 10a, 10a arranged in the front and rear sides and its upper and lower four corners connected by four wide depth frames 10b. The side plate 11 covers the upper and lower surfaces with a top plate and a bottom plate, and doors 2 and 3 are provided on the front and rear surfaces.

そして、前記奥行きフレーム１０の前後の内側にマウントレール１２を４本取り付けて、該マウントレール１２にサーバ等の電気・電子機器ユニット４を上下に段積するように取り付けて、キャビネット１の内部に電気・電子機器ユニット４を側板１１の間に空間部を形成して搭載するものとしている。   Then, four mounting rails 12 are attached inside the front and rear of the depth frame 10, and electric / electronic device units 4 such as servers are attached to the mounting rail 12 so as to be stacked vertically. The electrical / electronic device unit 4 is mounted with a space formed between the side plates 11.

また、電気電子機器収納用キャビネット１の前面の扉２と後面の扉３のどちらか一方すなわち後面の扉３には冷却装置５が設置されている。この冷却装置５により供給される冷風は、電気・電子機器ユニット４とキャビネット１の側板１１との間を水平方向に導く送風ダクト６の通風口６１から電気・電子機器ユニット４に供給するものとしている。これにより、冷風はキャビネット１の上下方向において均一の温度で供給されることとなり、上下に段積したサーバ、ネットワーク機器等の電気・電子機器ユニットは均一に冷却されるものである。   In addition, a cooling device 5 is installed on either the front door 2 or the rear door 3 of the electrical / electronic equipment storage cabinet 1, that is, the rear door 3. The cold air supplied by the cooling device 5 is supplied to the electric / electronic equipment unit 4 from the ventilation opening 61 of the air duct 6 that leads between the electric / electronic equipment unit 4 and the side plate 11 of the cabinet 1 in the horizontal direction. Yes. As a result, the cool air is supplied at a uniform temperature in the vertical direction of the cabinet 1, and the electrical and electronic device units such as servers and network devices stacked in the vertical direction are uniformly cooled.

また、冷却装置５は前記したとおり前面の扉２と後面の扉３のどちらか一方に設置したものであるので、冷却装置５によりキャビネット１の幅方向のサイズが大きくする必要がないので、データセンター等で多数の電気電子機器収納用キャビネットを連結した場合にもその分の場所を広くする必要がないものである。     Since the cooling device 5 is installed on either the front door 2 or the rear door 3 as described above, it is not necessary to increase the size in the width direction of the cabinet 1 by the cooling device 5. Even when a large number of electrical and electronic equipment storage cabinets are connected at a center or the like, it is not necessary to widen the space.

なお、前記冷却装置５は、図２、図３に示すようにシロッコファンよりなるファン５１と水冷式冷却器５２よりなる熱交換ユニット５０を後面の扉３に一体に組み込んだものである。図示のものは熱交換ユニット５０を扉３の上下に２個組み込んでいる。また、冷却装置５を設置した扉の内面には送風ダクト６の通風口６１より供給される冷風を電気電子機器収納用キャビネットに導くガイド片７を扉の上下に渡って設置することが好ましい。また、送風ダクト６を設けた側面と反対側の側面の側板とマウントレールとの間に遮蔽板を上下に渡って設けたものとしてもよい。   As shown in FIGS. 2 and 3, the cooling device 5 is one in which a heat exchange unit 50 composed of a fan 51 composed of a sirocco fan and a water-cooled cooler 52 is integrated into the rear door 3. The illustrated one incorporates two heat exchange units 50 above and below the door 3. Moreover, it is preferable to install the guide piece 7 which guide | induces the cold wind supplied from the ventilation port 61 of the ventilation duct 6 to the electrical / electronic equipment storage cabinet on the inner surface of the door which installed the cooling device 5 over the door. Moreover, it is good also as what provided the shielding board up and down between the side plate and the mounting rail of the side surface opposite to the side surface in which the ventilation duct 6 was provided.

すなわち、冷却装置５は、扉３を内壁３１と外壁３２よりなる二重構造としてその間に冷却機器組込空間３０を形成したものとして、内壁３１にキャビネット１の廃熱を吸引する吸気口３ａと冷風をキャビネット１内に循環させる排気口３ｂを前記２個の熱交換ユニット５０に対応させて上下に２個づつ設けたものである。   That is, the cooling device 5 is configured such that the door 3 has a double structure composed of an inner wall 31 and an outer wall 32 and a cooling device built-in space 30 is formed therebetween, and an intake port 3 a that sucks waste heat of the cabinet 1 into the inner wall 31. Two exhaust ports 3 b for circulating the cold air in the cabinet 1 are provided in correspondence with the two heat exchange units 50, one above the other.

また、前記水冷式冷却器５２は縦長のラジエータ５２ａにファン５１により吸引されて送風される廃熱を上下均一に冷却して該縦長のラジエータ５２ａと同じ縦寸法としたは縦長四角状の排気口３ｂから冷風をキャビネット１内に循環させるものである。   The water-cooled cooler 52 is configured to cool the waste heat sucked and blown by the fan 51 to the vertically long radiator 52a uniformly in the vertical direction so as to have the same vertical dimension as the vertically long radiator 52a. The cool air is circulated in the cabinet 1 from 3b.

また、キャビネット１内への冷風の循環は図２の矢印で示すように前記したとおり、電気・電子機器ユニット４とキャビネット１の側板１１との間を水平方向に導く送風ダクト６の通風口６１から電気・電子機器ユニット４に供給するものである。   Further, the circulation of the cold air into the cabinet 1 is as shown by the arrow in FIG. 2, and as described above, the ventilation opening 61 of the air duct 6 that guides the space between the electric / electronic device unit 4 and the side plate 11 of the cabinet 1 in the horizontal direction. Is supplied to the electric / electronic equipment unit 4.

前記送風ダクト６は図４、５に示すように扉３の内壁３１に設けた縦長四角状の排気口３ｂに連結する吸入ダクト部６ａと電気・電子機器ユニット４とキャビネット１の側板１２との間に配置する縦長扁平四角状の水平送風用ダクト部６ｂを連結したものである。そして、水平送風用ダクト部６ｂの先端と内側面のどちらか一方に電気・電子機器ユニット４に冷風を供給する通風口６１を設けるための開口を形成して、一方を閉塞して通風口６１を水平送風用ダクト部６ｂの先端と内側面のどちらか一方に変更して形成できるものとしている。   As shown in FIGS. 4 and 5, the air duct 6 includes an intake duct portion 6 a connected to a vertically long rectangular exhaust port 3 b provided on the inner wall 31 of the door 3, an electric / electronic device unit 4, and a side plate 12 of the cabinet 1. A vertically long and flat rectangular horizontal air duct 6b disposed between them is connected. And the opening for providing the ventilation port 61 which supplies cold air to the electric / electronic device unit 4 in either one of the front-end | tip and inner surface of the horizontal ventilation duct part 6b is formed, and one side is obstruct | occluded and the ventilation port 61 is closed. Can be formed by changing to either one of the front end and the inner side surface of the horizontal air duct 6b.

すなわち、図５に示すように送風ダクト６を、水平送風用ダクト部６ｂの先端を開口させるとともに内側面に開口を設けて、内側面に開口をブラインドパネル６２で覆い先端の開口を開口させた状態で通風口６１として、また、先端の開口を閉塞して側面の開口を覆うブラインドパネル６２を外して該内側面の開口を通風口６１とすることができるものとしている。   That is, as shown in FIG. 5, the air duct 6 was opened at the front end of the horizontal air duct portion 6b and provided with an opening on the inner surface, the opening was covered with the blind panel 62 on the inner surface, and the opening at the front end was opened. In this state, the ventilation opening 61 can be used as the ventilation opening 61 by removing the blind panel 62 that closes the opening at the tip and covers the opening on the side surface.

そうすると、送風ダクト６の通風口６１を、水平送風用ダクト部６ｂの先端の開口により形成して、冷却装置５を設置した前面又は後面に設けた扉２、３と対向する後面又は前面に設けた扉３、２に臨む電気・電子機器ユニット６の前面に冷風を供給するようにすれば、前面から冷風を吸い込む電気・電子機器ユニットであるサーバを効率よく冷却できるものである。   If it does so, the ventilation opening 61 of the ventilation duct 6 is formed by opening of the front-end | tip of the horizontal ventilation duct part 6b, and it provides in the rear surface or front surface which opposes the doors 2 and 3 provided in the front surface or rear surface which installed the cooling device 5. If cold air is supplied to the front surface of the electrical / electronic device unit 6 facing the doors 3 and 2, the server, which is an electrical / electronic device unit that draws cold air from the front surface, can be efficiently cooled.

また、送風ダクト６の通風口６１を、水平送風用ダクト部６ｂの側面の開口により形成して、電気・電子機器ユニット４の側面に冷風を供給するように設けたものとすると、側面から冷風を吸い込む電気・電子機器ユニット４であるネットワーク機器等を効率よく冷却できるものである。   In addition, when the ventilation duct 61 of the air duct 6 is formed by opening the side surface of the horizontal air duct portion 6b so as to supply the cold air to the side surface of the electric / electronic device unit 4, the cold air flows from the side surface. It is possible to efficiently cool the network device or the like which is the electric / electronic device unit 4 that sucks in the air.

さらに、通風口６１を水平送風用ダクト部６ｂの先端と内側面のどちらか一方に変更して形成できる送風ダクト６を、上下に複数すなわち図１に示すように２つ設ける。そして、上方の送風ダクト６の通風口６１を水平送風用ダクト部６ｂの先端の開口により形成して、冷却装置６を設置した前面又は後面に設けた扉２、３と対向する後面又は前面に設けた扉３、２に臨む電気・電子機器ユニット４の前面に冷風を供給するものとする。また、下方の送風ダクト６の通風口６１を水平送風用ダクト部６ｂの側面の開口により形成して、電気・電子機器ユニット４の側面に冷風を供給するものとする。   Further, a plurality of ventilation ducts 6 that can be formed by changing the ventilation openings 61 to either the front end or the inner side surface of the horizontal ventilation duct portion 6b are provided in the vertical direction, that is, as shown in FIG. And the ventilation opening 61 of the upper ventilation duct 6 is formed by opening of the front-end | tip of the horizontal ventilation duct part 6b, and the rear surface or front surface which opposes the doors 2 and 3 provided in the front surface or rear surface which installed the cooling device 6 is provided. It is assumed that cold air is supplied to the front surface of the electrical / electronic device unit 4 facing the provided doors 3 and 2. In addition, the ventilation opening 61 of the lower air duct 6 is formed by the opening on the side surface of the horizontal air duct portion 6 b, and cold air is supplied to the side surface of the electric / electronic device unit 4.

このよう通風口６１の異なる送風ダクト６を混在するように変更できるように設けるものとすれば、前面から又は側面から冷風を吸い込む２種類の電気・電子機器ユニット４であるサーバとネットワーク機器を上下に混在させて搭載しても、上下に設けた送風ダクト６の通風口６１をそれぞれの段に対応する電気・電子機器ユニット４の冷風吸込口に応じたものとすることができ効率のよい冷却ができるものである。なお、上記実施形態では、熱交換ユニットを２個設けたものとしたが、１個のみとしても、３個以上としてもよい。   If the air ducts 61 having different ventilation openings 61 can be changed so as to be mixed, the server and the network device, which are the two types of electric / electronic device units 4 for sucking cold air from the front surface or the side surface, are moved up and down. Even if they are mixed and mounted, the ventilation openings 61 of the air ducts 6 provided on the upper and lower sides can be made to correspond to the cold air intake openings of the electric / electronic device units 4 corresponding to the respective stages, so that efficient cooling is possible. It is something that can be done. In the above embodiment, two heat exchange units are provided. However, only one or three or more heat exchange units may be provided.

また、この実施形態の電気・電子機器キャビネットは、冷却装置５を組み込んだ後面の扉３を内壁３１と外壁３２よりなる二重構造としてその間に冷却機器組込空間３０を形成して、内壁３１にキャビネット１の廃熱を吸引する吸気口３ｂと冷風をキャビネット１内に循環させる排気口３ｂを前記２個の熱交換ユニット５０に対応させて上下に２個づつ設けて、図６に示すように外壁３２に前記排気口３ｂと対応させた窓孔３２ａを設けて覆板３２ｂで閉塞した構成で、廃熱をキャビネット内で冷却して循環させる所謂密閉型としたものである。   Further, in the electric / electronic equipment cabinet of this embodiment, the rear door 3 incorporating the cooling device 5 has a double structure composed of the inner wall 31 and the outer wall 32, and a cooling device built-in space 30 is formed between the inner wall 31 and the inner wall 31. As shown in FIG. 6, two intake ports 3b for sucking waste heat of the cabinet 1 and two exhaust ports 3b for circulating cool air into the cabinet 1 are provided corresponding to the two heat exchange units 50. Further, a window hole 32a corresponding to the exhaust port 3b is provided in the outer wall 32 and closed with a cover plate 32b, so that the waste heat is cooled and circulated in the cabinet to form a so-called sealed type.

このように、図７に示すように外壁３２に窓孔３２ａを設けて覆板３２ｂで閉塞した構成であるので、該覆板３２ｂを外して窓孔３２ａを開放させて前記排気口３ｂを閉塞して、また、前面の扉２をパンチングメタル、網板等の空気流通可能な扉に変更すれば、データセンター等の空気設備にて冷却された空気を、前面の扉２から吸入してキャビネット１内部に搭載した電気・電子機器ユニット４を冷却し、その廃熱をキャビネット１内の冷却装置で冷却した空気を窓孔３２ａから外部に排出する所謂開放型としても使用できるものである。   Thus, as shown in FIG. 7, since the window 32a is provided in the outer wall 32 and closed with the cover plate 32b, the cover plate 32b is removed and the window hole 32a is opened to close the exhaust port 3b. In addition, if the front door 2 is changed to a door that allows air to flow, such as punching metal or a mesh board, the air cooled by the air equipment such as the data center is sucked from the front door 2 and the cabinet. 1 can be used as a so-called open type in which the electric / electronic device unit 4 mounted inside 1 is cooled, and the air whose waste heat is cooled by the cooling device in the cabinet 1 is discharged to the outside from the window hole 32a.
