Abstract
Description
そこで、上記着霜現象の発生を抑える、すなわち、複数のチューブの各表面に生じる凝縮水の排除を促し得る熱交換器として、複数のチューブを上下方向に沿わせるようにして配置する、いわゆる冷媒縦流れタイプの熱交換器が開発されている。
上記した冷媒縦流れタイプの熱交換器では、チューブ及びフィンの本数が大幅に増加する都合上、複数のチューブ及びフィン個々に対して高い寸法精度が求められ、加えて、ヘッダパイプに多数のチューブ及びフィンの接続孔を所定のピッチで形成する際には、厳しい加工精度が要求されることから、熱交換器の生産性が低下するおそれがある。
また、上記従来の熱交換器は、熱交換器構成体同士の接続によって熱交換器を構成することで生じるおそれのある、熱交換効率の低下、熱交換器構成体のユニット化に伴う外観性の低下及びコンパクト化の弊害については格別な配慮がなされていない。
好ましくは、サイドプレートは断面L字形状をなす。
好ましくは、サイドプレートは、互いに隣接するコア部間と対向する嵌合部間とで囲まれた間隙を遮蔽するようにして互いに連結される。
好ましくは、サイドプレートは、連結部に、ボルトを挿通することで対向するサイドプレートを互いに連結可能とするボルト挿通孔を有し、ボルト挿通孔は、対向するサイドプレートがコア部への通風方向において互いに非接触で間隙を遮蔽可能とする位置に形成されている。
好ましくは、サイドプレートは、互いに隣接するコア部において対向するコア部の端縁部への取り付け方向をコア部への空気の通風方向でみて前後対称に異ならしめた同一品である。
また、本発明によれば、サイドプレートが互いに隣接するコア部間と対向する嵌合部間とで囲まれた間隙を遮蔽するようにして互いに連結されることにより、熱交換器においてコア部間の空気の逃げ通路を閉塞することができることができ、熱交換器に通風される空気の全量をコア部に通風させることができる。従って、空気と冷媒との熱交換が促進され、熱交換器の熱交換効率を高めることができる。
また、本発明によれば、サイドプレートは、互いに隣接するコア部において対向するコア部の端縁部への取り付け方向をコア部への空気の通風方向でみて前後対称に異ならしめた同一品であることにより、熱交換器の構成部品の製造及び管理が容易となるため、熱交換器の生産性を更に高めることができる。
図1は本発明の一実施形態に係る熱交換器1の正面図である。熱交換器1は冷媒縦流れタイプの熱交換器であって、2個の熱交換器構成体2,2を左右方向に並列配置して構成されている。
また、入口側及び出口側サイドプレート20,22は、ヘッダパイプ4,6にそれぞれチューブ接続孔14と等ピッチで形成されたプレート接続孔26にろう付けにより接合され、入口側及び出口側サイドプレート20,22とこれらに隣接するチューブ8との間にはフィン10が設けられている。なお、図中における符号28は、熱交換器構成体2の左右端部に位置するフィン10を押さえるカバーである。
一方、図5に示すように、連結部30は隣接するコア部12の対向するサイドプレート20(又は22)の連結部30と連結される。連結部30には、ボルト34を挿通することで対向する入口側及び出口側サイドプレート20,22を互いに連結可能とするボルト挿通孔36が形成されている。ボルト挿通孔36は、対向する入口側及び出口側サイドプレート20,22がコア部12への通風方向において互いに非接触で間隙24を遮蔽可能とする位置に形成され、ボルト34のねじ部の直径よりも大きい直径を有する丸孔である。このボルト挿通孔36にボルト34を挿通してナット38を締結することで、対向する入口側及び出口側サイドプレート20,22の寸法誤差及び組立誤差を吸収しながら互いの連結方向に段差を生じること無く連結することができる。
また、入口側及び出口側サイドプレート20,22は、互いに隣接するコア部12間と対向する上側及び下側嵌合部16,18間とで囲まれた間隙24を遮蔽するようにして互いに連結されることにより、熱交換器1においてコア部12間の空気の逃げ通路を閉塞することができることができ、熱交換器1に通風される空気の全量をコア部12に通風させることができる。従って、空気と冷媒との熱交換が促進され、熱交換器1の熱交換効率を高めることができる。
また、入口側サイドプレート20と出口側サイドプレート22とは、互いに隣接するコア部12において対向するコア部12の端縁部12aへの取り付け方向をコア部12への空気の通風方向でみて前後対称に異ならしめた同一品であることにより、熱交換器1の構成部品の製造及び管理が容易となるため、熱交換器1の生産性を更に高めることができる。
例えば、上記実施形態では、入口側及び出口側サイドプレート20,22は断面L字形状をなして形成されている。しかし、連結部30において対向する入口側及び出口側サイドプレート20,22がコア部12への通風方向において互いに非接触で間隙24を遮蔽可能とする位置にボルト挿通孔36が形成されるのであれば、この形状に限定されない。
また、図7に示すように、入口側及び出口側サイドプレート46,48に、これらの接続部32が互いに対向する向きに折曲した屈曲部50を設け、コア部12への空気の通風方向でみて前後対称に異ならしめた同一品となる断面U字形状をなすように形成しても良い。
しかも、サイドプレートを断面U字形状に形成することで、断面L字形状とする場合に比してサイドプレートの剛性を高め、その耐久性を向上させることができる。
また、上記実施形態では、熱交換器1が2個の熱交換器構成体2,2を左右方向に並べて配置した場合を説明したが、これに限定されるものではなく、熱交換器構成体2を3個以上並べる構成としても良い。
