Description

【0001】
【発明の属する技術分野】
本発明は、設置スペースが限られており、内部に発熱体を有し、その発熱量が多く冬季においても冷却を要し、また、温度、湿度、粉塵などが電子部品の性能、寿命に影響を与えるような精密な制御基板を有する発熱体収納箱の冷却装置に関するものである。
【0002】
【従来の技術】
近年、電子部品の高性能化と制御基板に対する電子部品の高密度化が進み、制御基板からの発熱量は飛躍的に増加している。これに伴い、箱内の温度は上昇する傾向にあり、制御基板上にある電子部品の動作保証、製品寿命は箱内の温度に大きな影響を受ける。このため、箱内の温度を一定以下に冷却しなければ信頼性の確保が出来なくなってきている。
【0003】
また、電子部品の精密化によって箱内の空気中の水分、粉塵を除去することも重要な要素になってきている。
【0004】
従来、この種の冷却装置としては、特開2000−161875号公報に記載されているものがあった。図13は、前記公報に記載された従来の冷却装置を示すものである。
【0005】
以下、その冷却装置について図13を参照しながら説明する。
【0006】
図に示すように、冷却装置101は、密閉空間内の高温空気(本発明では内気)流と外気である低温空気流との熱交換を行う熱交換器102と、高温空気流を熱交換器102に生じさせる高温用遠心ファン103と、低温空気流を熱交換器102に生じさせる低温用遠心ファン104と、これらを内包する箱体105とから構成され、高温空気流を低温空気流によって冷却するようになっていた。
【0007】
そして、遠心ファン(本発明では送風機)と熱交換素子の配置は、熱交換素子を間に配し縦一列に配列されているものであった。
【0008】
また、この冷却装置101のように従来の冷却装置は、吸込口からでる空気の吸込方向と吹出口の排気方向の関係は、互いにほぼ並行となっていた。
【0009】
【発明が解決しようとする課題】
しかしながら、前記従来の構成では、冷却装置の配置が、熱交換素子を間に配した縦一列に配列されているため長方形の形状となり、一辺の長さが長くなりコンパクトな構成にしにくいという課題があった。
【0010】
本発明は、前記従来の課題を解決するもので、内気送風機と外気送風機を隣接させ、両方の送風機の吹出側に熱交換素子を配列することにより、コンパクトで薄型の冷却装置を提供することを目的とする。
【0011】
また、低温空気(外気)の吸込方向と低温(外気)吹出口の排気方向が並行となり、排気された暖かい空気が吸込口に回り込みショートサーキットという現象をおこし易いという課題があった。
【0012】
本発明は、前記従来の課題を解決するもので、排気された暖かい空気が吸込口に回り込みにくい冷却装置を提供することを目的とする。
【0013】
また、前記箱内の空気を取り込む内気送風機の吹出口の高さh1と外気を取り込む外気送風機の吹出口の高さh2が熱交換素子高さh3と異なる場合、高さの違いにより熱交換素子に均等に風があたらず熱交換素子の機能が発揮されないという課題があった。
【0014】
本発明は、前記従来の課題を解決するもので、内気送風機の吹出口の高さh1と外気を取り込む外気送風機の吹出口の高さh2を熱交換素子高さh3と略同一にできるようにし送風機吹出口の空気をなるべく損失のない状態で熱交換素子に供給するための冷却装置を提供することを目的とする。
【0015】
また、箱体に結露水などの水滴が発生した場合、外気吸込口、外気吐出口に水滴が侵入したり、屋外に設置された場合などは雨などが侵入し易いという課題があった。
【0016】
本発明は、前記従来の課題を解決するもので、発生した水滴を外気吸込口、外気吐出口に水滴が侵入しないようにし、さらに雨などの侵入を防ぐカバーを設け、ショートサーキット現象をなくす冷却装置を提供することを目的とする。
【0017】
また、箱体が金属で出来ている場合は金属がアンテナのような役割を果たして電波障害を起こすという課題があった。
【0018】
本発明は、前記従来の課題を解決するもので、箱体の材料を樹脂にすることにより電波障害を大幅に軽減できる冷却装置を提供することを目的とする。
【0019】
また、発熱体収納箱内が高い温度になったときに急激な冷却が必要になるという課題があった。
【0020】
本発明は、内気用ダンパーと外気用ダンパーを備え、発熱体収納箱内が高い温度になった時には外気を導入することのできることを目的とする。
【0021】
【課題を解決するための手段】
上記課題を解決するための本発明における冷却装置の一つの手段は、発熱体収納箱に連通した内気吸込口と内気吹出口を有し、外気と連通し設けられた外気吸込口と外気吹出口とを有した箱体と、この箱体内に内気を搬送する内気送風機と、外気を搬送する外気送風機と、内気と外気の顕熱を交換する熱交換素子を設け、前記内気吸込口と前記外気吸込口とは相互に反対面に位置させるとともに、前記内気送風機と前記外気送風機とを相互に隣接させ、内気風路と外気風路を風路仕切板で仕切り、前記熱交換素子を前記内気送風機と前記外気送風機の吹出側に配置したことを特徴とする冷却装置である。
【0022】
また、発熱体収納箱内の空気を取込み、また発熱体収納箱内に戻し循環させる内気風路と、外気を取込み、また外気に排出する外気風路を有し、これら両風路が独立するように設置された風路仕切板と、外気風路の空気を搬送する外気送風機と、内気風路の空気を搬送する内気送風機と、前記外気送風機より吹出す外気と前記内気送風機より吹出す内気の顕熱を交換する熱交換素子とを備え、前記外気を取込む方向と前記外気の排出する方向が略垂直をなすことを特徴とした冷却装置である。
【0023】
また、発熱体収納箱に連通した内気吸込口から空気を取り込む内気送風機の吹出口の高さh1と外気を取り込む外気送風機の吹出口の高さh2が熱交換素子高さh3と略同一寸法となる冷却装置である。
【0024】
また、外気吸込口の周囲に立ちあがった外気吸込口リブがあり、外気吹出口の周囲に立ちあがった外気吹出口リブを設け、前記外気吸込口と前記外気吹出口をカバーで覆い、前記外気吸込口と前記外気吹出口の間に断熱性のある外気仕切板を設けた冷却装置である。
【0025】
また、箱体を樹脂としたことを特徴とする冷却装置である。
【0026】
また、内気用ダンパーと外気用ダンパーを備え、発熱体収納箱内が高い温度になった時に外気を導入することのできる冷却装置である。
【0027】
【発明の実施の形態】
本発明の請求項1に記載の発明は、発熱体収納箱に連通した内気吸込口と内気吹出口を有し、外気と連通し設けられた外気吸込口と外気吹出口を有した箱体と、この箱体内に内気送風機と、外気送風機と、熱交換素子を設けたものである。
【0028】
前記内気吸込口と前記外気吸込口を反対面に設けることにより、パネルなどに取付けた場合内気と外気を完全に遮断できる。箱体内の配置は、前記内気送風機と前記外気送風機を隣接させ、前記熱交換素子を前記内気送風機と前記外気送風機の吹出側に配置することにより、箱体の形状が正方形に近いものとなり最もコンパクトにすることができる。
【0029】
本発明の請求項2に記載の発明は、発熱体収納箱内の空気を取込み、また発熱体収納箱内に戻し循環させる内気風路と、外気を取込み、また外気に排出する外気風路がある。
【0030】
これら両風路が独立するように設置された仕切板と、外気風路の空気を搬送する外気送風機と、内気風路の空気を搬送する内気送風機と、前記外気送風機より吹出す外気と前記内気送風機より吹出す内気の顕熱を交換する熱交換素子とを備えている。
【0031】
この外気を取込む方向と外気の排出する方向は略垂直であるため排気された空気は外気吸込側に到達しにくくなり、その結果、外気空気は常に比較的低い温度の空気を供給することができるようになる。
【0032】
すなわち、最大の目的である内気の冷却が最も効率的に行える排気方向となる。
【0033】
なお、排気方向が異なる複数の外気吹出口をもつことにより、1つの排気口に障害物があったとしても、他の外気吹出口で排気できるため、外気への開口面積を充分確保することができる。
【0034】
本発明の請求項3に記載の発明は、発熱体収納箱に連通した内気吸込口から空気を取り込む内気送風機の吹出口の高さh1と外気を取り込む外気送風機の吹出口の高さh2とを熱交換素子高さh3と略同一寸法とすることにより、空間の無駄が少なく構成部材配置上最も効率がよい。
【0035】
さらに、送風機の吹出口の高さh1、h2から吹出された空気が熱交換素子全体にあたるため熱交換素子内での熱交換効率がよくなる。
【0036】
本発明の請求項4に記載の発明は、外気吸込口と外気吐出口の周囲に立ちあがりリブを設け、前記外気吸込口と前記外気吹出口をカバーで覆い、前記外気吸込口と前記外気吹出口の間に断熱性のある外気仕切板を設けたものである。
【0037】
外気吸込口と外気吹出口の周囲に立ちあがりリブを設けることにより、結露水が発生し外気吸込口や外気吹出口に流れて来たとしても、リブにより結露水の侵入を防ぐことができる。
【0038】
また、屋外の雨などがかかる条件の時にも外気吸込口と外気吹出口をカバーなどで覆うことにより、雨からの侵入を防ぐことができる。
【0039】
なお、カバーなどで覆ったときに外気吸込口と外気吹出口がショートサーキット現象を起こすため、外気吸込口と外気吹出口との間に外気仕切板を設けることにより、ショートサーキットを防ぐことができる。
【0040】
前記外気仕切板は、外気の吸込空気と外気の吹出空気が仕切られた空間に隣接して流れるため、材料としては熱を通しにくい断熱材料を用いることにより外気の吹出空気の温度が外気の吸込空気に伝わりにくくすることができる。
【0041】
本発明の請求項5に記載の発明は、箱体を樹脂としたことによって金属などで発生する電波障害を大幅に軽減できるため、発熱体収納箱の内部への影響を防ぐことができる。
【0042】
本発明の請求項6に記載の発明は、内気用ダンパーと外気用ダンパーを備え、発熱体収納箱内が高い温度になった時に、そのダンパーを使い外気を導入することのできるようにしたものである。
【0043】
【実施例】
以下、本発明の実施例について添付図面を参照しながら説明する。
【0044】
(実施例1)
図1、図2は本願発明における冷却装置の基本構造ともいえる実施例1を示したものである。
【0045】
本実施例による冷却装置は、発熱体収納箱のパネルの外郭(図示せず)に取付けられ、いわゆる「外付け」装着で、内気吸込み面がパネルに取付けられている。
【0046】
以下、その内部構造について説明する。
【0047】
箱体1には、内気側に内気吸込口2をもった内気を搬送する内気送風機3が配置され、それと隣接するように外気吸込口6をもった外気を搬送する外気送風機7が配置され、内気送風機3と外気送風機7の吹出側に内気と外気の顕熱を交換する熱交換素子4を配置してある。
【0048】
内気吸込口2は発熱体収納箱の内部に連通し、外気吸込口6は外気と連通し、お互いが反対面に位置するように設けられている。
【0049】
内気風路と外気風路は、風路仕切板1aで内気と外気が連通しないように仕切られている。
【0050】
上記構成により、箱体1は、外気温度の低い外気を取り入れ、発熱体収納箱内部の暖かい空気との間で熱交換素子4にて熱交換をおこない、暖かくなった外気は排気し、冷たくなった空気を箱内に導入する。
【0051】
これにより熱交換による冷却と外気を導入することなく冷却を行うことが可能となるため、簡易な構成となり省スペース、省施工で発熱体収容箱の冷却を実現することができる。
【0052】
(実施例2)
図3、図4は本願発明における冷却装置の基本風路構成ともいえる実施例2を示したものである。
【0053】
箱体1の内部の配置は外気送風機7を下に置き内気送風機3を上に隣接させ両送風機の吹出側の横に熱交換素子4を置いた場合の風路構成について説明する。
【0054】
発熱体収納箱内の空気は内気吸込口2から内気送風機3に取込まれ、熱交換素子4を通過したのち、また内気吹出口5から発熱体収納箱内に戻り循環する内気風路を形成している。
【0055】
一方、箱体1の外気吸込口6より外気を取込み、外気送風機7、熱交換素子4、外気吹出口8aを介して、また外気に排出する外気風路を形成している。
【0056】
上記構成により、箱体1は、外気温度の低い外気を取り入れ、発熱体収納箱内部の暖かい空気との間で熱交換素子4にて熱交換をおこない、その熱交換により暖かくなった外気はふたたび排気し、外気との熱交換により冷却された発熱体収納箱内の空気をふたたび発熱体収納箱に戻す。
【0057】
なお、本実施例の図3のように、外気吸込口6の外気を取込む方向と外気吹出口8aの外気の吹出方向が略垂直になる関係がもっともシヨートサーキットを起こしにくい方向であるが、設置の制約等により、側面以外の箱体1の上部、外気吸気面から排気してもかまわない。
【0058】
このように、吹出方向が異なる複数の外気吹出口を設けることにより一つの排気口に障害物があったとしても、他の外気吹出口で開口面積を確保することができる。
【0059】
(実施例3)
図5は本願発明における冷却装置の実施例3を示したものである。
【0060】
本実施例は箱内の空気を取り込む内気送風機3の吹出口の高さh1と外気を取り込む外気送風機7の吹出口の高さh2が熱交換素子4の高さh3と略同一寸法となるようにしたものである。
【0061】
内気送風機3、外気送風機7の吹出口から出た空気を熱交換素子4内で内気と外気を均等に流すためには、吹出口の高さh1、h2と熱交換素子4の高さh3を同一にするのが箱内の空間の無駄が少なく構成部材配置上最も効率が良い。
【0062】
(実施例4)
図6は本願発明における冷却装置の実施例4を示したものである。
【0063】
本実施例は外気吸込口6の周囲に外気吸込口リブ9、外気吹出口8bの周囲に外気吹出口リブ10を設けることにより、結露水などの水滴がリブの外周を伝わり、外気吸込口6などに侵入しないように結露水を逃がす役目をもっている。
【0064】
なお、外気吹出口8bの形状は吸込口の開口面積より大きければ、形状は三角、四角、丸などでもよい。
【0065】
図6では、熱交換素子で形成される吹出し部分の空間を最大限利用して三角形状の外気吐出口8bとしたものである。
【0066】
箱体1の外気吸込口6と外気吹出口8bをカバー11で覆っている。
【0067】
カバー11の内部は、外気を吸う外気吸込グリル12と外気を排出する外気吹出グリル13が設けられている。
【0068】
カバー11の役目は屋外で使用された場合の雨の防止をおこなうことである。吸込空気と排気の空気が反対方向から排気されるため、排気空気が回り込みにくくなっている。
【0069】
なお、外気吸込口6と外気吹出口8bがショートサーキット状態になるため外気吸込グリル12と外気吹出グリル13の間に断熱材料の外気仕切板14を入れてショートサーキットを防ぐとともに断熱効果により外気吸込空気と外気吹出空気の熱伝導をおこりにくくしている。
【0070】
外気吹出空気の熱が外気吸込空気に伝わらなければ外気吸込空気は低い温度の空気を保つことができる。
【0071】
(実施例5)
本実施例は、前記実施例の説明に用いた図1〜4および図6〜7まで全て共通する内容である。
【0072】
一般に、発熱する電子部品を内部に大量に有する発熱体収納箱は、それ自身から電磁波を発生しやすく、箱体1も金属でできている場合は、金属がアンテナの役割をして電波障害がおこりやすい。
【0073】
箱体1は樹脂で囲まれているため、上記電波障害がおこりにくく金属などの導体で発生する電波障害を大幅に軽減でき、電波障害をなくす手段の一つとして有力な方法である。
【0074】
(実施例6)
図9、図10、図11、図12は本願発明におけるダンパーを使った冷却装置の実施例6を示したものである。
【0075】
図9は内気循環の状況を示した内気風路断面図である。
【0076】
風路を変更する内気ダンパー15aが熱交換素子4の入口を開放した時の箱体1の内気用ダンパー15a動作と内気の流れを示したものである。
【0077】
発熱体収納箱内の空気は内気吸込口2から内気送風機3に取込まれ、熱交換素子4を通過して、のち、また内気吹出口5から発熱体収納箱内に戻り循環する内気風路を形成している。
【0078】
図10は外気循環の状況を示した外気風路断面図である。
【0079】
風路を変更する外気ダンパー16aが熱交換素子4の入口を開放した時の箱体1の外気用ダンパー16a動作と外気の流れを示したものである。
【0080】
発熱体収納箱内の空気は外気吸込口6から外気送風機7に取込まれ、熱交換素子4を通過して、のち、また外気吹出口8から発熱体収納箱内に戻り循環する外気風路を形成している。図9、図10のように内気用ダンパー15a、外気用ダンパー16aにより熱交換素子4で熱交換する場合の風路構成は、外気温度の低い外気を取り入れ、発熱体収納箱内部の暖かい空気との間で熱交換素子4にて熱交換をおこない、暖かくなった外気は排気し、冷たくなった空気を箱内に給気している。
【0081】
しかしながら、発熱体収納箱内部が異常に高い温度となった場合には、外気による急激な冷却が必要になってくる。
【0082】
以下にダンパーを使い発熱体収納箱内部を外気により直接冷却する方法について説明する。
【0083】
図11は内気排出の状況を示した内気風路断面図である。
【0084】
風路を変更する内気ダンパー15aが熱交換素子4の入口を閉塞した時の箱体1の内気用ダンパー15a動作と内気の流れを示したものである。
【0085】
発熱体収納箱内の空気は内気吸込口2から内気送風機3に取込まれ、内気出口17から外気へ放出される。
【0086】
一方、図12は外気導入の状況を示した外気風路断面図である。
【0087】
風路を変更する外気ダンパー16aが熱交換素子4の入口を閉塞した状態を示し、箱体1の外気用ダンパー16aの動作と外気の流れを示したものである。
【0088】
発熱体収納箱内の空気は外気吸込口6から外気送風機7に取込まれ、発熱体収納箱内に外気入口18から放出される。
【0089】
外気で直接冷却するため急激な温度の低下をおこなうことができる。
【0090】
このようなダンパーを使う方法を用いれば発熱体収納箱内の急激な温度上昇においても対応できる。
【0091】
【発明の効果】
以上のように本発明によれば、発熱体収納箱のパネルに設置する簡易な構成で、箱内を密閉した状態で外気導入による熱交換による冷却ができる。
【0092】
外気吸込口にリブを設け水滴の侵入防止をし、カバーをつけて雨の侵入防止をはかる構造も可能としている。
【0093】
さらに、発熱体収納箱内部の温度が高温になったときのためにダンパーを用いて外気の導入をはかることもできる。

Was supposed to.
[0007]
The arrangement of the centrifugal fan (the blower in the present invention) and the heat exchange element is such that the heat exchange elements are arranged therebetween and arranged in a vertical line.
[0008]
In a conventional cooling device such as the cooling device 101, the relationship between the suction direction of the air coming out of the suction port and the exhaust direction of the air outlet is almost parallel to each other.

[0045]
The cooling device according to the present embodiment is attached to the outer shell (not shown) of the panel of the heating element storage box, and the inside air suction surface is attached to the panel by so-called “external attachment”.
[0046]
Hereinafter, the internal structure will be described.
[0047]
Inside box 1 is provided with inside air blower 3 which conveys inside air having inside air suction port 2 on the inside air side, and outside air blower 7 which conveys outside air having outside air suction port 6 is arranged adjacent thereto. A heat exchange element 4 for exchanging sensible heat between the inside air and the outside air is arranged on the blowout side of the inside air blower 3 and the outside air blower 7.
[0048]
The inside air suction port 2 communicates with the inside of the heat generating element storage box, and the outside air suction port 6 communicates with the outside air, and is provided so that they are located on opposite surfaces.
[0049]
The inside air passage and the outside air passage are partitioned by an air passage partition plate 1a so that the inside air and the outside air do not communicate with each other.
[0050]
With the above configuration, the box body 1 takes in the outside air having a low outside air temperature, performs heat exchange with the warm air inside the heating element storage box in the heat exchange element 4, exhausts the warmed outside air, and cools down. Introduced air into the box.

[0052]
(Example 2)
FIG. 3 and FIG. 4 show a second embodiment which can be regarded as a basic wind path configuration of the cooling device according to the present invention.
[0053]
The arrangement of the inside of the box 1 will be described with respect to an air path configuration in a case where the outside air blower 7 is placed below, the inside air blower 3 is placed above and the heat exchange element 4 is placed beside the blowout side of both blowers.
[0054]
The air inside the heating element storage box is taken into the inside air blower 3 from the inside air suction port 2, passes through the heat exchange element 4, and then returns from the inside air blowout port 5 to the inside of the heating element storage box to form an internal air passage that circulates. are doing.
[0055]
On the other hand, outside air is taken in from the outside air suction port 6 of the box body 1, and an outside air passage is formed through the outside air blower 7, the heat exchange element 4, and the outside air outlet 8 a to be discharged to the outside air.
[0056]
With the above-described configuration, the box 1 takes in outside air having a low outside air temperature, performs heat exchange with the warm air inside the heating element storage box in the heat exchange element 4, and the outside air warmed by the heat exchange is returned. The air in the heating element storage box cooled by heat exchange with the outside air is returned to the heating element storage box again.
[0057]
As shown in FIG. 3 of the present embodiment, the relationship in which the direction of taking in the outside air from the outside air inlet 6 and the direction of the outside air blowing out of the outside air outlet 8a are almost perpendicular is the direction in which the short circuit is least likely to occur.

Heat conduction between the air and the outside air is hardly generated.
[0070]
If the heat of the outside air blown air is not transmitted to the outside air suction air, the outside air suction air can keep the low temperature air.
[0071]
(Example 5)
This embodiment has the same contents in all of FIGS. 1 to 4 and FIGS. 6 and 7 used in the description of the embodiment.
[0072]
In general, a heating element storage box having a large amount of electronic components that generate heat easily generates electromagnetic waves from itself, and when the box body 1 is also made of metal, the metal acts as an antenna and causes electromagnetic interference. Easy to get offended.
[0073]
Since the box 1 is surrounded by resin, the above-mentioned radio interference is less likely to occur, and the radio interference generated by a conductor such as a metal can be greatly reduced. This is an effective method as one of means for eliminating the radio interference.
