摘要： PURPOSE: An oil cooler for an air flow channel of a gas turbine engine is provided to improve heat exchange efficiency by reducing air flow wake at the trailing edges of inner air fins. CONSTITUTION: An oil cooler for an air flow channel of a gas turbine engine comprises an oil flow section(10), inner air fins(12), outer air fins(14), and diverting planes. The oil flow section delivers heated oil flow in a layer approximately parallel to a wall(4) of an air flow channel. The inner air fins are projected from the side of the oil flow section, separate from and parallel to the wall, and extended in the direction of air flow passing through the air flow channel. The diverting planes are projected toward air so that the air flow gets away from the inner air fins through the air flow channel and heads toward the outer air fins.
摘要翻译：目的：提供一种用于燃气涡轮发动机的空气流动通道的油冷却器，以通过减少内部空气翅片的后缘处的气流尾流来提高热交换效率。构成：用于燃气涡轮发动机的空气流动通道的油冷却器包括油流部分（10），内部空气翅片（12），外部空气翅片（14）和转向平面。油流部分在与空气流动通道的壁（4）大致平行的层中输送加热的油流。内部空气翅片从油流部分的侧面突出，与壁分离并平行于壁，并且沿着通过空气流动通道的空气流的方向延伸。转向平面朝向空气投射，使得气流通过空气流动通道离开内部空气散热片并朝着外部空气翅片朝向头部。
