Abstract
【解決手段】 ラジエータ16とオイルクーラ17は、冷却ファン9の前面側に冷却風の流れ方向に対して並列に配置し、インタクーラ18とコンデンサ19は、ラジエータ16とオイルクーラ17の前面側に位置して並列に配置し、燃料クーラ21は、コンデンサ19の前面側に配置する構成とする。従って、冷却風の流れ方向の上流側から下流側に向け、発熱量が順次大きくなるように各熱交換器16〜19,21を配置することにより、冷却すべき流体の熱を効率よく放出することができる。また、燃料クーラ21をコンデンサ19の前面側に配置することにより、インタクーラ18の厚さ寸法の範囲に2つの熱交換器19,21を収めることができる。
