<p><P>PROBLEM TO BE SOLVED: To provide a heat exchange system of air and lubricating oil of which thrust loss and capacity are reduced in a compact space in an advanced turbo fan engine. <P>SOLUTION: This heat exchange system performs heat exchange of the air and the working fluid in order to cool the working fluid in the air stream on the stream side of a wall, and is used for a fluid operation device. An actuator is provided with a motion effector capable of designating a position, and is attached to be positioned substantially on a wall side opposite from the stream side. A heat exchange core 20 is provided with a plurality of passage structure bodies 21 capable of supplying and removing the working fluid in the inside thereof. The heat exchange core is attached in such a manner of being expandable and removable in a region occupied by the air stream by the motion effector through an opening for a selected distance. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
