しかし、従来の空調システムでは、冷却した空気の搬送距離が長くなると共に、無駄な空間まで冷却していることになる。更に、複数のサーバーがある場合に、稼働していないサーバーまで冷却することになり、冷却効率を向上させることが困難である。本発明に係る発熱体用冷却装置は、このような課題を解決するために提案されたものである。   However, in the conventional air-conditioning system, the transport distance of the cooled air is increased and cooling is performed to a useless space. Furthermore, when there are a plurality of servers, the servers that are not in operation are cooled, and it is difficult to improve the cooling efficiency. The cooling device for a heating element according to the present invention has been proposed in order to solve such a problem.

本発明に係る発熱体用個別冷却装置の上記課題を解決して目的を達成するための要旨は、前・後壁と循環ダクトを有する側壁と天井部及び床面とで発熱体を収納する内部閉空間を形成するとともに、前記天井部に設けた循環ファンで前記側壁と天井部及び内部閉空間に空気を循環させる躯体装置と、前記躯体装置の側壁の一部を形成する躯体であって循環空気ダクトを一体に有して前記天井部と内部閉空間とに連通し、前記躯体装置に設けられた開閉機構によって開閉自在に支持される可動式エンベロープと、前記可動式エンベロープ又は前記天井部に設けられる熱交換器と、前記熱交換器に冷媒を供給する冷媒供給配管と、循環する空気の温度を計測して前記循環ファンの回転速度を制御する制御装置とから構成されて前記発熱体を個別に冷却することである。   The gist for solving the above-mentioned problems of the individual cooling device for a heating element according to the present invention is to provide an interior for housing the heating element with front and rear walls, side walls having circulation ducts, a ceiling portion and a floor surface. A housing device that forms a closed space and circulates air to the side wall, the ceiling portion, and the internal closed space by a circulation fan provided in the ceiling portion, and a housing that forms a part of the side wall of the housing device and circulates A movable envelope that is integrated with an air duct and communicates with the ceiling portion and the internal closed space, and is supported by an opening / closing mechanism provided in the housing device so as to be freely opened and closed, and the movable envelope or the ceiling portion. A heat exchanger provided; a refrigerant supply pipe for supplying a refrigerant to the heat exchanger; and a control device for controlling the rotational speed of the circulation fan by measuring the temperature of the circulating air. Individually It is to retirement.

前記 隔壁は、開閉自在であること、；
前記躯体装置における前壁若しくは後壁には、人の出入り口用扉が適宜に設けられていること、；
を含むものである。 The housing apparatus is appropriately provided with a partition wall for partitioning the heating elements when there are a plurality of heating elements housed in an internal closed space;
The partition is openable and closable;
A door for a person's doorway is appropriately provided on the front wall or the rear wall of the housing apparatus;
Is included.

本発明に係る発熱体用冷却装置によれば、循環空気用のピットが不要となり、空調室工事に掛かるコストを飛躍的に削減することができる。また、個々のサーバーなどの通信機器の運転状況に合わせて、循環ファンを制御し適切な除去熱量となるように管理することが可能となる。よって、無駄に冷却する様なことが避けられる。また、本発明に係る発熱体用冷却装置は、標準化設計が可能であり、製造コストを低減させることができる。更に、発熱体用冷却装置における冷却能力は、コイル層数やフィン本数の設定を除去熱量に対応して行うことができるので、将来の除去熱量の変更にも同一のコンセプトで対応可能である。   According to the cooling device for a heating element according to the present invention, a pit for circulating air becomes unnecessary, and the cost required for the air conditioning room construction can be drastically reduced. In addition, the circulation fan can be controlled and managed so as to have an appropriate amount of heat to be removed in accordance with the operation status of communication devices such as individual servers. Therefore, unnecessary cooling is avoided. In addition, the cooling device for a heating element according to the present invention can be standardized and can reduce the manufacturing cost. Furthermore, since the cooling capacity in the cooling device for a heating element can be set according to the amount of heat removed, the number of coil layers and the number of fins can be set, so that it is possible to cope with future changes in the amount of heat removed with the same concept.

また、前記躯体装置に隔壁を設けることで、内部閉空間に収納する発熱体が複数ある場合に、運転状況に応じて適宜に発熱体同士を仕切ることができて、冷却効率を高めることが容易となる。この隔壁をジャバラ式や引き戸式などの開閉式にすれば、容易に仕切ることができて使い勝手が良くなる。更に、空調室の設置場所の形や大きさの制限により、人の出入り口用扉を利用したり、可動式エンベロープを開閉したりして、能率良くメンテナンス等を行うことができる。   In addition, by providing a partition wall in the housing device, when there are a plurality of heating elements to be housed in the internal closed space, the heating elements can be partitioned appropriately according to the operating conditions, and it is easy to increase the cooling efficiency. It becomes. If this partition wall is of an open / close type such as a bellows type or a sliding door type, the partition can be easily partitioned and the usability is improved. Furthermore, due to restrictions on the shape and size of the installation location of the air conditioning room, maintenance and the like can be performed efficiently by using a door for a person's doorway or opening and closing a movable envelope.

本発明に係る発熱体用冷却装置１は、図１−Ａ及び図２に示すように、前壁・後壁１ａ，１ｂと循環ダクト及び熱交換器２を有する側壁１２ａ，１２ｂ，…１２ｅ，…と天井部８及び床面７（建物の床又は装置１の床部）とで発熱体４を収納する内部閉空間１３を形成するとともに、前記天井部８に設けた循環ファン６で前記側壁１２ａ，…，１２ｅと天井部８及び内部閉空間１３に空気を循環させる躯体装置１２がある。   As shown in FIGS. 1A and 2, the heating element cooling device 1 according to the present invention includes front and rear walls 1a and 1b, circulation ducts and side walls 12a, 12b,. ... and the ceiling portion 8 and the floor surface 7 (the floor of the building or the floor portion of the apparatus 1) form an internal closed space 13 in which the heating element 4 is stored, and the side wall is formed by the circulation fan 6 provided in the ceiling portion 8 12a,..., 12e and a casing device 12 that circulates air through the ceiling portion 8 and the internal closed space 13.

前記躯体装置１２の側壁の一部を形成する躯体であって循環空気ダクトを一体に有して前記天井部８と内部閉空間１３とに連通し、前記躯体装置１２に設けられた開閉機構３によって開閉自在に支持される可動式エンベロープ５がある。この可動式エンベロープ５は、図２に示すように、側壁１２ａ，…の両側に一対で設けられる場合もあるし、片側だけに設けられる場合もある。また、この躯体装置１２の大きさによっては、片側の側壁に複数個の可動式エンベロープ５が設けられる場合もある。   A casing forming a part of the side wall of the casing device 12, which has a circulating air duct integrally and communicates with the ceiling portion 8 and the internal closed space 13, and an opening / closing mechanism 3 provided in the casing device 12. There is a movable envelope 5 that can be opened and closed freely. As shown in FIG. 2, the movable envelope 5 may be provided as a pair on both sides of the side walls 12a,... Or may be provided only on one side. Further, depending on the size of the housing apparatus 12, a plurality of movable envelopes 5 may be provided on one side wall.

この可動式エンベロープ５の内部には、上下方向に連通する間隙があり、循環する空気の通り道となっている。更に、内側壁面には循環空気用の開口部が複数設けられている。この開口部の空気の吸込み側には、塵埃除去用のフィルター等が備えられている。この可動式エンベロープ５の内部に、熱交換器２が装備されている。   Inside the movable envelope 5, there is a gap communicating in the vertical direction, which is a passage for circulating air. Furthermore, a plurality of openings for circulating air are provided on the inner wall surface. A filter for removing dust is provided on the air suction side of the opening. A heat exchanger 2 is installed inside the movable envelope 5.

前記熱交換器２は、循環空気を、水以外の冷媒（代替フロンなど）で冷却するコイルがあり、空気の流れの抵抗を極力少なく、かつ、伝熱効率を改善したフィンが装備されている。また、上下方向に連通するダクトがあってその内側壁面には循環空気用の開口部が複数設けられた循環空気ダクトを一体構造としている。前記開閉機構３は、公知の開閉技術であり、例えば、エアーシリンダーや油圧装置等の駆動手段により、回転軸が回転されたり、直接的にエンベロープ５をロッド等で押し上げたりするものである。   The heat exchanger 2 has a coil for cooling the circulating air with a refrigerant other than water (such as alternative chlorofluorocarbon), and is equipped with fins that minimize the resistance to air flow and improve the heat transfer efficiency. In addition, a circulating air duct having a duct communicating in the vertical direction and having a plurality of openings for circulating air on its inner wall surface has an integrated structure. The opening / closing mechanism 3 is a known opening / closing technique. For example, the rotating shaft is rotated by driving means such as an air cylinder or a hydraulic device, or the envelope 5 is directly pushed up by a rod or the like.

前記熱交換器２に冷媒を供給する冷媒供給配管１０と、循環する空気の温度を例えば熱交換器２の入口または出口において温度センサー等で入口温度または出口温度を計測して、前記循環ファン６の回転速度を制御する制御装置１１（図示せず）とある。以上のようにして本発明の発熱体用冷却装置１が構成される。   The refrigerant supply pipe 10 for supplying the refrigerant to the heat exchanger 2 and the temperature of the circulating air are measured, for example, at the inlet or outlet of the heat exchanger 2 by a temperature sensor or the like, and the circulation fan 6 And a control device 11 (not shown) for controlling the rotation speed of the motor. As described above, the heating element cooling device 1 of the present invention is configured.

そして、前記内部閉空間１３に収納される発熱体４は、例えば、サーバーなどの通信機器であって、一つの発熱体若しくは一群の発熱体である。これによって、温度管理をし易くするものである。   The heating element 4 accommodated in the internal closed space 13 is, for example, a communication device such as a server, and is one heating element or a group of heating elements. This facilitates temperature management.

なお、前記躯体装置１２においては、内部閉空間１３に複数の発熱体４を収納する場合もあり、その場合には、発熱体４同士を仕切る必要があるので、隔壁９が設けられることがある。この隔壁９は断熱性の高い部材で形成したものである。更に、この隔壁９をジャバラ式若しくは引き戸式で開閉自在にして、内部に納める一群の発熱体４の長さに容易に対応可能にできる。   In the housing apparatus 12, a plurality of heating elements 4 may be accommodated in the internal closed space 13, and in that case, since the heating elements 4 need to be partitioned from each other, a partition wall 9 may be provided. . The partition wall 9 is formed of a highly heat insulating member. Further, the partition wall 9 can be opened and closed by a bellows type or a sliding door type, so that it can easily correspond to the length of the group of heating elements 4 accommodated therein.

更に、図３に示すように、冷却装置１を設置する空調室の設置面積や壁の都合により、可動式エンベロープ５をエアーシリンダーや油圧装置等で駆動される開閉機構３で開閉できない場合がある。そのような場合に、メンテナンス等の必要から内部に人が出入りできるよう、例えば、前壁１２ａに、人の出入口用扉１１が適宜設けられている。   Furthermore, as shown in FIG. 3, the movable envelope 5 may not be opened and closed by an opening / closing mechanism 3 driven by an air cylinder, a hydraulic device, or the like due to the installation area of the air conditioning room where the cooling device 1 is installed and the convenience of the wall. . In such a case, for example, a person entrance door 11 is appropriately provided on the front wall 12a so that a person can go in and out because of maintenance or the like.

前記発熱体用冷却装置１の使用方法について説明すると、図１−Ａに示すように、循環ファン６の駆動回転によって冷却装置１の内部閉空間１３内に冷気が吹き出されて発熱体４の熱を吸熱して、側壁１２ａ，１２ｂ，…及び可動式エンベロープ５内の熱交換器２へと流れてここで熱交換される。熱交換器２には、図４に示すように、冷媒供給配管１０の枝管である供給官１０ａによって冷凍機（図示せず）から冷媒が供給され、戻し管１０ｂによって前記冷凍機に並列的に戻され、外部に熱が放熱されるものである。   The method of using the heating element cooling device 1 will be described. As shown in FIG. 1-A, the cooling fan 1 is driven and rotated to blow cold air into the internal closed space 13 of the cooling device 1 to heat the heating element 4. , And flows into the heat exchanger 2 in the side walls 12a, 12b,... And the movable envelope 5, where heat is exchanged. As shown in FIG. 4, the heat exchanger 2 is supplied with refrigerant from a refrigerator (not shown) by a supplier 10a, which is a branch pipe of the refrigerant supply pipe 10, and in parallel with the refrigerator by a return pipe 10b. The heat is returned to the outside and the heat is radiated to the outside.

前記熱交換器２によって熱が吸収された空気が冷気となって循環空気ダクトを介して天井部８に至り、前記循環ファン６により内部閉空間１３に再び吹き出されて循環する。この循環ファン６は、制御装置（図示せず）によって無駄なく適切に、回転制御される。   The air whose heat has been absorbed by the heat exchanger 2 becomes cold air and reaches the ceiling portion 8 through the circulation air duct, and is blown out again and circulated by the circulation fan 6 into the internal closed space 13. The circulation fan 6 is appropriately controlled to rotate without waste by a control device (not shown).

即ち、前記熱交換器２の入口または出口の近傍に温度センサー（図示せず）を配設して、温度の変化を信号として受信して、前記制御装置で循環ファン６を独立に制御してこれの回転数を増減するものである。このように、個々若しくは一群の発熱体４に対して熱輸送をローカル化して、熱輸送効率を向上させるものである。更に、この制御装置は、前記冷媒供給配管１０における供給のＯＮ，ＯＦＦを電磁弁等で制御することも含まれる。   That is, a temperature sensor (not shown) is provided near the inlet or outlet of the heat exchanger 2 to receive a change in temperature as a signal, and the circulation fan 6 is independently controlled by the controller. The number of rotations is increased or decreased. In this way, heat transport is localized with respect to the individual or group of heating elements 4 to improve heat transport efficiency. Further, the control device includes controlling the supply ON / OFF in the refrigerant supply pipe 10 with an electromagnetic valve or the like.

このようにすることで、サーバー等の発熱体４の運転状況により、循環ファン６の回転数を適切な回転数で回転させ、更に、冷媒を供給する必要のないところには、無駄に供給することがないように設定できる。よって、従来の空調システムのように、稼働していないサーバーがあっても、空調室の全体を冷却する、という無駄なことも本発明に係る発熱体用冷却装置１では避けられる。   By doing in this way, the rotation speed of the circulation fan 6 is rotated at an appropriate rotation speed according to the operation state of the heating element 4 such as a server, and further, it is wastefully supplied to a place where it is not necessary to supply the refrigerant. It can be set so that nothing happens. Therefore, even if there is a server that is not in operation as in a conventional air conditioning system, the waste of cooling the entire air conditioning room can be avoided in the heating element cooling device 1 according to the present invention.

また、発熱体４若しくは発熱体４の一群を、前記側壁１２ａ，１２ｂ，…及び可動式エンベロープ５によって近接させて覆うようにしたので、循環させる空気の熱輸送の距離が短く、無駄な空間まで冷却することがなく熱効率が良いと共に、循環ファン６が小型化されて発生する熱量も抑えられるものである。   Further, since the heating element 4 or a group of heating elements 4 is covered and covered by the side walls 12a, 12b,... And the movable envelope 5, the heat transport distance of the circulated air is short, and the useless space is reached. The heat efficiency is good without cooling, and the amount of heat generated by reducing the size of the circulation fan 6 can be suppressed.

本発明に係る他の実施例の発熱体用冷却装置１ｃとして、図１−Ｂに示すように、空気の循環する方向を上記実施例の空気の流れに対して逆にし、内部閉空間１３から循環ファン６で天井部８へと発熱体４の熱を吸収した暖かい空気を吸い込み、側壁１２ａ，１２ｂ，…及び可動式エンベロープ５に送り出して熱交換器２で放熱させて、冷気を内部閉空間１３に吹き出すようにして循環させることもできる。前記発熱体４で熱せられた空気が自然に上昇するので、循環ファン６の負荷が軽減される。   As shown in FIG. 1B, as a cooling device 1c for a heating element according to another embodiment of the present invention, the air circulation direction is reversed with respect to the air flow of the above-described embodiment. The warm air that has absorbed the heat of the heating element 4 is sucked into the ceiling portion 8 by the circulation fan 6 and is sent to the side walls 12a, 12b,... It is also possible to circulate as if it were blown to 13. Since the air heated by the heating element 4 naturally rises, the load on the circulation fan 6 is reduced.

また、図１−Ｃに示す他の実施例ように、熱交換器２を天井部８に纏めて設けて、側壁１２ａ，１２ｂ，…及び可動エンベロープ５は循環空気ダクトにしてなる発熱体用冷却装置１ｄとすることもできる。このようにすることで、側壁１２ａ，１２ｂ，…と可動式エンベロープ５の構造が簡易になり製作が容易になり、また、可動式エンベロープ５の重量が軽量化されて、これを開閉させる開閉機構３の負荷も軽減される。   Further, as in another embodiment shown in FIG. 1-C, the heat exchanger 2 is provided on the ceiling portion 8 and the side walls 12a, 12b,... And the movable envelope 5 are circulating air ducts. It can also be the device 1d. By doing so, the structure of the side walls 12a, 12b,... And the movable envelope 5 is simplified and the manufacture is facilitated, and the weight of the movable envelope 5 is reduced, and the opening / closing mechanism that opens and closes it. The load of 3 is also reduced.
