Description
以下、本発明の第1実施形態について図1〜図5に基づいて説明する。本実施形態では、本発明の熱交換器を排気熱交換器(EGRクーラ)に適用した例を説明する。
次に、本発明の第2実施形態について図6に基づいて説明する。本第2実施形態では、チューブ21およびインナーフィン22の芯材20の表面に形成された被膜30が、芯材20よりも電位が卑になっている。本例では、被膜30はAl2O3により構成されている。
次に、本発明の第3実施形態について図7に基づいて説明する。本第3実施形態では、図7に示すように、チューブ21およびインナーフィン22の芯材20の表面に、芯材20よりも電位が貴となる第1耐食被膜31および第2耐食被膜32が、複数交互に積層形成されている。
次に、本発明の第4実施形態について図7に基づいて説明する。本第4実施形態では、図8に示すように、チューブ21およびインナーフィン22の芯材20の表面に、結晶状態であって、かつ、芯材20よりも電位が貴となる耐食被膜33と、アモルファス状態であって、かつ、芯材20よりも電位が卑となる犠牲被膜34とが、複数交互に積層形成されている。耐食被膜33および犠牲被膜34は、それぞれ、アトミックレイヤーデポジションにより形成されている。
次に、本発明の第5実施形態について図9および図10に基づいて説明する。本第5実施形態は、上記第1実施形態と比較して、熱交換器の製造工程にろう付け工程が含まれない、すなわちチューブをフィン等にろう付け接合することなく機械的に固定する点が異なるものである。本実施形態では、本発明の熱交換器を、エンジン(内燃機関)の冷却水と空気とを熱交換してエンジン冷却水を冷却するラジエータ100に適用した例を説明する。
本発明は上述の実施形態に限定されることなく、本発明の趣旨を逸脱しない範囲内で、以下のように種々変形可能である。
22 インナーフィン(熱交換器構成部品)
30 被膜
