Abstract
Description
この電子機器冷却装置の筐体は、直方体形状の内ケース、中間ケースおよび外ケースを有する三重構造をなしている。発熱する部品は内ケースに内蔵されている。内ケースには、内気ファンが付設されるとともに、内気ファンと対向する側が開口部とされている。また、中間ケースは、内ケースを囲むとともに内ケースと対向する4面を同様に囲繞するコルゲートルーバーフィンを有する。また、外ケースは、中間ケースを囲むとともに中間ケースと対向する4面を同様に囲繞するコルゲートルーバーフィンを有する。さらに、外ケースには、外気ファンが付設されるとともに、外気ファンと対向する側が開口部とされている。これにより、特許文献1に記載された電子機器冷却装置によれば、内気ファンおよび外気ファンの送風により対流を起こすとともに、ケース相互間の4面を囲繞するコルゲートルーバーフィンにより、内ケース内の熱を効率良く放熱できるとしている。
本発明は、このような問題点に着目してなされたものであって、発熱する部品が内蔵される直方体形状の筐体を有する電子機器冷却装置において、直方体形状の筐体の互いに隣接して直交する二つの面を効率良く冷却することができる電子機器冷却装置およびこれを備える電力変換装置を提供することを目的としている。
(構成1)この電子機器冷却装置は、前記筐体の第一の側壁面に放熱用の側壁フィンが形成されるとともに、前記筐体の底面に放熱用の底部フィンが形成されている。
(構成2)さらに、この電子機器冷却装置は、前記側壁フィンおよび前記底部フィンが外側からカバー部で覆われている。
(構成4)さらに、この電子機器冷却装置は冷媒供給装置を有する。冷媒供給装置は、前記チャンバー部の外側面に設けられた冷媒導入口から前記チャンバー室内に向けて冷媒を供給する。
(構成5)さらに、この電子機器冷却装置は、前記チャンバー室内に配置される平板状の仕切り部を有する。仕切り部は、前記側壁フィンおよび前記底部フィンが形成されている前記筐体の二つの面それぞれに向けて前記冷媒導入口からの冷媒を振り分けるように斜めに仕切る。
また、チャンバー室内には、側壁フィンおよび底部フィンが形成されている筐体の二つの面それぞれに向けて冷媒導入口からの冷媒を振り分けるように斜めに仕切る平板状の仕切り部が配置されているので、互いに隣接して直交する二つの面に対し、各面の発熱比率に応じた所望量に冷媒を振り分けることができる。したがって、この電子機器冷却装置によれば、直方体形状の筐体の互いに隣接して直交する二つの面を効率良く冷却することができる。
冷媒が空気の場合において、送風ファンが、筐体の第一の側壁面寄りであって二つの面相互が共有する一辺がつくる角寄りの位置に装着されるとともに、仕切り部が、二つの面相互が共有する一辺がつくる角を含む仮想傾斜面に沿って自身の平板状の面が配置されていれば、一つの送風ファンによって、互いに隣接して直交する二つの面に対し、各面の発熱比率に応じた所望の送風量を振り分ける上でより好適である。
図1に示すように、この電力変換装置1は、直方体形状の筐体2を有する。この筐体2には、その長尺方向の一方の側面に、冷媒供給装置としての送風ファン3が外付けされている。また、筐体2の長尺方向の他方の側面には、入力コネクタ4、制御コネクタ5、および出力コネクタ6が並列して設けられている。筐体2内には、後述する電力変換制御ユニットが内蔵されており、制御コネクタ5に制御信号を入力すると、入力コネクタ4に入力された商用電力が、電力変換制御ユニットにより交流から直流に変換されて出力コネクタ6から直流電力として出力されるようになっている。
また、図3に示すように、ケース7の底部7aにも、その下面の左端部から右側までの領域に、長尺方向に延在する複数の底部フィン13が形成されている。これら複数の底部フィン13は、底部7aの短尺方向に所定間隔をあけて平行に形成されている。図4に示すように、各底部フィン13のフィン高さは、側壁フィン12のフィン高さH1よりも大きな値H2(H2>H1)に設定されている。さらに、底部フィン13のピッチは、側壁フィン12のピッチP1よりも大きな値P2(P2>P1)に設定されている。
このように、筐体カバー9で覆われたケース7の底部7a及び一方の長辺側壁7eの外周に、図3に示すように、複数の側壁フィン12の間の空間及び複数の底部フィン13の間の空間が、ケース7の長手方向に延在する複数の流路27,28となっている。そして、上記蓋体10が、ケース7及びチャンバー形成壁8の上部開口部を閉塞するようにケース7及びチャンバー形成壁8に固定されている。これにより、ケース7の一方の短辺側壁7bと、チャンバー形成壁8と、筐体カバー9と、蓋体10とで囲まれた内方側の空間が、チャンバー室11として画成されている。
ここで、上記チャンバー室11の内部には、平板状の仕切り部30が設けられている。この仕切り部30は、筐体2の互いに隣接して直交する二つの面となっているケース7の長辺側壁7eと底板9a(以下、これら長辺側壁7eと底板9aとを単に「二つの面」とも呼ぶ)それぞれに向けて送風ファン3からの送風を振り分ける仕切り部材である。なお、本実施形態の仕切り部30は、筐体2を構成するケース7にダイカスト成形によりケース7と一体形成された突出部から構成されている。つまり、この突出部からなる仕切り部30は、ケース7の短辺側壁7bを基端部とするとともにチャンバー11側に向けて張り出し、送風ファン3からの送風を振り分けるように斜めに形成されている。
そして、ベース基板15に、上記の入力側ノイズフィルタ部16、第1リアクトル17、第2リアクトル18、電界コンデンサ群19、出力側ノイズフィルタ部21、半導体デバイスD1~D12及び第1~第3回路基板23~25が実装され、ベース基板15の切欠き部15aの内側に配置したトランス20がケース7の底部7aに直に接触するように固定されているとともに、ベース基板15上に内部ファン14が配置されている。
半導体デバイスD1~D6は、ベース基板15の一方の短辺に沿って並び方向に所定間隔をあけて実装されている。これら半導体デバイスD1~D6の位置は、チャンバー室11を画成しているケース7の一方の短辺側壁7bに直に接触するように実装されている。他の半導体デバイスD7~D12は、ベース基板15の一方の長辺に沿って並び方向に所定間隔をあけて実装されている。これら半導体デバイスD2~D12の位置は、側壁フィン12を形成しているケース7の一方の長辺側壁7eに直に接触するように実装されている。
本実施形態の電力変換装置1は、制御コネクタ5に制御信号を入力すると、入力コネクタ4に入力された商用電力が、ケース7内部に収納した電力変換制御ユニットにより交流から直流に変換され、出力コネクタ6から直流電力として出力される。この際、ケース7内のトランス20や電力変換制御ユニット等の制御部品が発熱し、特に、半導体デバイスD1~D12、トランス20、第1リアクトル、第2リアクトル、電界コンデンサ群19の自己発熱が高くなる。
ここで、上記二つの面7a,7eに対し、長辺側壁7eと交差する方向を向く短辺側壁7bに対向してチャンバー室11が配置されるとともに、チャンバー室11を画成する対向壁8bの外側面には、冷媒導入口となる矩形状の開口部8cからチャンバー室11内に向けて送風をする送風ファン3が装着されているので、図7の矢印Ra、Rbで示すように、一つの送風ファン3によって、チャンバー室11を介して上記二つの面7a,7eそれぞれに向けて送風することができる。そして、この電力変換装置1によれば、上記二つの面7a,7eの放熱用のフィン12,13がその外側から筐体カバー9で覆われているので、送風ファン3による送風の流路27,28をフィン12,13の周囲に形成しつつ、フィン12,13から効率良く放熱することができる。
また、半導体デバイスD7~D12は、冷却体となるケース7の一方の長辺側壁7eに直に接触するように実装されているので、冷風が図7の矢印Rbで示すように、長辺側壁7eの複数の流路27を流れることで、半導体デバイスD7~D12で発生した熱は一方の長辺側壁7eに効率良く放熱され、半導体デバイスD7~D12を確実に冷却することができる。
また、第1リアクトル、第2リアクトル及び電界コンデンサ群19で発生した筐体2内部の熱は、内部ファン14の駆動により発生するケース7内を循環する冷風により確実に冷却される。なお、ケース7を循環する冷風は、冷却体であるケース7の一方の短辺側壁7b及び一方の長辺側壁7e、並びにケース7の底部7aに接触して放熱されるので、第1リアクトル、第2リアクトル及び電界コンデンサ群19の周囲を冷風が循環することで冷却効果を高めることができる。
また、送風ファン3が、筐体2の長辺側壁7e寄りであって二つの面7a,7e相互が共有する一辺がつくる角K寄りの位置に装着されるとともに、仕切り部30が、二つの面7a,7e相互が共有する一辺がつくる角Kを含む仮想傾斜面Lkに沿って自身の平板状の面が配置されているので、一つの送風ファン3によって、互いに隣接して直交する二つの面7a,7eに対し、各面7a,7eの発熱比率に応じた所望の送風量を振り分ける上で好適である。
また、上記仕切り部30は、筐体2を構成するケース7と一体形成された突出部からなり、この突出部は、短辺側壁7bを基端部とするとともにチャンバー室11側に向けて張り出して形成されているので、直方体形状の筐体2の互いに隣接して直交する二つの面7a,7eそれぞれに向けて送風ファン3からの送風を振り分けるという機能を、筐体2と一体形成する上で好適である。
例えば、上記実施形態では、平板状の仕切り部30が、筐体2を構成するケース7にダイカスト成形により一体形成された突出部から構成されている例で説明したが、これに限定されるものではない。例えば、仕切り部30を、ケース7とは別個の部品として設け、チャンバー室11の内部に着脱可能に装着することができ、また、この場合に、自身の平板状の面の傾斜角度を調整可能に構成することができる。図8にこのような構成の変形例を示す。
ここで、傾斜角度を調整可能に構成していれば、同図に示す例において、長辺側壁7e(側壁フィン12側)と底板9a(底部フィン13側)相互に向けた送風量を振り分けるに際し、開口部8cに対して仕切り部30を同図の30Bの位置(傾斜角度が45°よりも大きい長辺側壁7e寄りの位置)に装着すれば、長辺側壁7e(側壁フィン12側)への送風量よりも底板9a(底部フィン13側)への送風量を多くすることができる。
また、例えば上記第一実施形態では、冷媒として空気を用い、冷媒供給装置として送風ファンを設けた例で説明したが、本発明は、これに限らず、冷媒として水を用いてもよい。以下、第二実施形態について図9~13を参照しつつ説明する。
第二実施形態の電力変換装置1は、例えば電気自動車やハイブリッド自動車等に搭載されるバッテリーを充電する用途に用いられる。図9に第二実施形態のシステム構成を示すように、本実施形態では、冷却水を循環させるために、熱交換器50、リザーバタンク60およびポンプ70を備えている。電力変換装置1には、冷却水供給口41と冷却水排出口42とが筐体2の外部に露出して設けられている。冷却水排出口42は、排出用配管43を介して熱交換器50に接続されている。熱交換器50は、車両に搭載された空冷ラジエータ等を適用することができる。冷却水供給口41は、供給用配管46を介してポンプ70に接続されている。熱交換器50とポンプ70との間には、冷却水を貯留するリザーバタンク60が設けられ、リザーバタンク60は、配管44、45によって熱交換器50とポンプ70にそれぞれ接続されている。
ここで、上記第一実施形態では、冷媒が空気なので、チャンバー室11は、完全な密閉が不要であるのに対し、第二実施形態の電力変換装置1では、図10~図13に示すように、チャンバー室11の画成空間、およびチャンバー室11に連通する側壁フィン12と底部フィン13を囲む空間(以下、「冷却室」ともいう)は、周囲が確実に液封され、これにより、チャンバー室11および「冷却室」からの冷却水の漏れが防止されている。
また、筐体2の上部を覆う蓋体10は着脱可能であるが、筐体カバー9およびチャンバー形成壁8の上端面と蓋体10の裏面との間は、相互の接合面間にパッキンが介装されている。本実施形態の例では、筐体カバー9およびチャンバー形成壁8の上端には、フランジ部8g、9gが形成されている。そして、そのフランジ部8g、9gの上面、および筐体カバー9およびチャンバー形成壁8の上端面に、上部開口を囲繞するように液体パッキン10pを塗布しており、蓋体10をねじ等でフランジ部8g、9gに固定することにより、チャンバー室11および「冷却室」の上部開口を液封して、蓋体10の裏面部分から冷却水が漏れること防止している。
