PROBLEM TO BE SOLVED: To provide an aircraft heat exchanger that can restrain fluid from flowing out at the time of stoppage.SOLUTION: A heat exchanger comprises: a fluid flow passage through which fluid flows and in which heat is exchanged; an inlet part (12 and 14) that supplies the fluid to the fluid flow passage 11; an outlet part (13 and 15) that discharges the fluid from the fluid flow passage; and a short-circuit flow passage 50a that connects the inlet part (12 and 14) and the outlet part (13 and 15). The cross-sectional area of the short-circuit flow passage 50a can be 0.1 to 5% of the cross-sectional area of the inlet part (12 and 14) and 0.1 to 5% of the cross-sectional area of the outlet part (13 and 15).SELECTED DRAWING: Figure 5
【課題】停止時に流体が流出するのを抑制できる航空機用熱交換器を提供する。【解決手段】熱交換器は、流体が流通し、熱交換が行われる流体流路と、流体流路11に流体を供給する入口部(12、14)と、流体流路から流体を排出する出口部(13、15)と、入口部(12、14)と出口部(13、15)とを接続する短絡流路50aとを備える。短絡流路50aの横断面の面積を、入口部(12、14)の横断面の面積の0.1〜5%とし、かつ、出口部(13、15)の横断面の面積の0.1〜5%とすることができる。【選択図】図5
