そして、車両用熱交換構造10が適用された自動車Aでは、フロアトンネル20の前側の開口端20Aを塞ぐように、冷却ユニット25が設けられている。したがって、この実施形態では、冷却ユニット25がパワーユニット12に対する後側に配置されている。冷却ユニット25は、水冷式のパワーユニット12(のエンジンや電気モータ)との間で冷却液としての冷却水を循環させて該パワーユニット12を冷却するラジエータ25Rを少なくとも含んで構成されている。この実施形態では、冷却ユニット25は、後述する空調装置40を構成する空冷式の熱交換器であるコンデンサ25Cを含んで構成されている。
図1に示される如く、空調装置40は、パワーユニット室14の後端における上部に配置された熱交換部42と、車室C側に設けられたインストルメントパネル44内に設けられた吹き出し切換部46とを含んで構成されている。熱交換部42は、ダッシュパネル16に対する前側で該ダッシュパネル16に支持されたケース48を備えている。ケース48の上側開口部は、図2にも示されるカバー50にて閉止されている。

他方、パワーユニット12の冷却要求が通常であり、かつ空調装置40が作動されている(ONの)場合、すなわち、冷気流との混合の有無に関らず少なくともヒータコア66による空調空気の加熱要求がある場合、空調モードとされる。この空調モードでは、第2ブロア62が作動されると共に、空調側ダンパ82がケース48の温気出口48Hoを開放する位置に位置される。また、排気ダンパ80は、排気ダクト78を閉止する位置に位置される。
先ず、パワーユニット12の冷却要求が高い場合であって、かつ空調装置40の作動が停止されている(OFFの)場合、ヒータコア66によりパワーユニット12の冷却を行う冷機モードとされる。この冷機モードでは、第2ブロア62及びファン26が作動される。さらに、空調側ダンパ82は温気出口48Hoを閉止する位置に位置され、排気ダンパ80は排気ダクト78を開放する位置に位置される。
一方、パワーユニット12の冷却要求が高い場合であって、かつ空調装置40が作動されている(ONの)場合、すなわち、冷気流との混合の有無に関らず少なくともヒータコア66による空調空気の加熱要求がある場合、複合モードとされる。この複合モードでは、第2ブロア62及びファン26が作動される。さらに、空調側ダンパ82は温気出口48Hoを開放する位置に位置され、排気ダンパ80は排気ダクト78を開放する位置に位置される。
次に、本発明の第2の実施形態に係る車両用熱交換構造100について、図5に基づいて説明する。なお、基本的に上記第1の実施形態と同様に構成された部品、部分については、上記第1の実施形態と同一の符号を付す。また、これらについて説明、図示を省略する場合がある。
