Abstract
【解決手段】扁平断面形状を有し、内部に流体が流れる複数本のチューブ1、チューブ1の扁平面10に接合されるフィン2を備える熱交換器であって、フィン2は、板面を有する平板部2a、および平板部2aの板面から突出するルーバ2cを有し、ルーバ2cは、チューブ1の扁平面10に対して所定距離離間して設けられている。チューブ1は、扁平面10において空気の流れの抵抗となるように突出する抵抗体11として複数のディンプル11aを有し、前述の所定距離を非切れ部長さLとしたときに、抵抗体11(複数のディンプル11a)は、扁平面10の直交方向の突出高さHが、非切れ部長さL以上となるように設けられている。
【選択図】図2
Description
E=(α/αs)/(dPa/dPas)1/3…(F1)
ここで、αとdPaは、ディンプル11aを有する熱交換器の熱伝達率(α)と摩擦抵抗力を示し、αsとdPsはディンプル11aを有しない熱交換器の熱伝達率と摩擦抵抗力を示している。なお、数式F1は、「Principles of Enhanced Heat Transfer, Second Edition(著者 Ralph L. Webb, Nae-Hyun Kim、出版社 Taylor & Francis p.58,59)」に記載のようにポンプ動力一定とした熱交換器等の伝熱性能の評価値Eを示す一般的な数式である。
以上、本発明の実施形態について説明したが、本発明はこれに限定されるものではなく、各請求項に記載した範囲を逸脱しない限り、各請求項の記載文言に限定されず、当業者がそれらから容易に置き換えられる範囲にも及び、かつ、当業者が通常有する知識に基づく改良を適宜付加することができる。例えば、以下のように種々変形可能である。
1/K=(1/αa)+{Fa/(αw・Fw)}+t/λ…(F3)
ここで、Kは熱通過率、ΔTmは対数平均温度、αaは空気側の熱伝達率、αwはエンジン冷却水側の熱伝達率、Faは空気側の放熱面積、Fwはエンジン冷却水側の放熱面積、tはチューブ1の板厚、λはチューブ1の熱伝導率を示している。
