PROBLEM TO BE SOLVED: To provide an aircraft heat exchanger that can lower a rise in temperature of a seal member in a fire disaster to secure fire resistance.SOLUTION: The aircraft heat exchanger 10 includes: an auxiliary flow passage 60a branching from a main flow passage; a valve 70 for opening and closing the auxiliary flow passage 60a; the seal member 63 for sealing between members forming the auxiliary flow passage 60a; and a relief flow passage 71a for connecting an upstream side to a downstream side of the valve 70. A transverse section area of the relief flow passage 71a is smaller than that of the auxiliary flow passage 60a.SELECTED DRAWING: Figure 5
【課題】火災の際のシール部材の昇温を低減でき、耐火性を確保できる航空機用熱交換器を提供する。【解決手段】主流路から分岐する補助流路60aと、補助流路60aを開閉する弁70と、補助流路60aを形成する部材間を封止するシール部材63とを備える航空機用熱交換器10であって、弁70の上流側と下流側とを接続する逃がし流路71aをさらに備え、逃がし流路71aの横断面の面積は、補助流路60aの横断面の面積よりも小さい。【選択図】図5
