空気冷却器。A plurality of double cooling pipes having an inner pipe and an outer pipe shorter than the inner pipe are arranged inside the fuselage along the axial direction, and the ends of these cooling pipes are connected to a tube plate provided at the end of the fuselage. A side plate, into which the outer tube is inserted, is disposed with a predetermined gap between the tube sheet into which the inner tube is inserted, and a side plate into which the outer tube is inserted is inserted into the gap. An air cooler characterized in that springs are attached whose axial ends abut the end faces of the outer tube.
