放熱器1は、航空機用放熱器であり、伝熱部2と、放熱部3(図2参照)と、放熱ダクト4とを備えている。伝熱部2は、複数の伝熱性の高い金属製の板材2aを複数積層して接着することにより構成されている略直方体の部材である。伝熱部2は、タキシングモータコントローラ200及びコンプレッサモータコントローラ120と接触しており、タキシングモータコントローラ200及びコンプレッサモータコントローラ120の熱を放熱部3へと伝える。
放熱促進部3bは、放熱板3aから冷却空気への熱伝達率を向上させるために放熱板3aに複数設けられている。この放熱促進部3bは、例えば放熱板3aをプレス加工することにより形成されており、図3に示すように、放熱板3aの接触面である第1面においては凹部であると共に、対向する接触面である第2面の同一位置においては凸部となっている。第1面及び第2面の法線方向から見た放熱促進部3bの輪郭は、図4に示すように、長手方向に沿う基準軸Xに対して対称である。また、放熱促進部3bの輪郭は、基準軸X上に中心を有する大円C1(大きい円)と大円C1より径の小さい小円C2(小さい円)とを配置し、大円C1と小円C2との共通接線L1より僅かに外側に膨らんだ曲線により結ばれている。放熱促進部3bの輪郭は、大円C1と、小円C2と、共通接線L1より僅かに外側に膨らんだ曲線とによって得られた図形の外形形状とされている。すなわち、放熱促進部3bの輪郭は、基準軸Xに沿って小円C2から大円C1に向かう方向において、小円C2の中心を越えて広がる形状に設定されている。また、放熱促進部3bの基準軸Xが冷却空気の主流の流動方向に沿うように配置されることで、基準軸Xに沿って大円C1が冷却空気の流れ方向下流側となり、小円C2が冷却空気の流れ方向上流側となる。放熱促進部3bの輪郭は、冷却空気の主流の流動方向の上流に向かう面が湾曲した形状となっている。
放熱促進部3bは、図2に示すように、冷却空気の流れ方向に沿う方向に多数配列されると共に、冷却空気の流れ方向と交差する方向に複数配列されている。
タキシングモータコントローラ200は、航空機の航行時に回路に負荷がかかることにより発熱し、表面温度が上昇する。タキシングモータコントローラ200に接触した状態の伝熱部2は、放熱部3の放熱板3aにタキシングモータコントローラ200の熱を伝達する。
さらに、熱が伝達された冷却空気は、コンプレッサ110により吸い上げられた後、冷却システム100の外側へと排出される。
