Each first layered header passage has an open end at a first edge adjacent to the first header space and communicates with the first header space through the open end. The plurality of first communication port rows are arranged in the perpendicular direction so as to correspond to the plurality of first layered header passages, respectively. Each first communication port row is formed by a plurality of first communication ports arranged along the reference plane. The plurality of first passages communicate with any of the first layered header passages through the plurality of first communication ports.

A heat exchanger includes a first fluid inlet, a first fluid outlet, a second fluid inlet, a second fluid outlet, and a core section. The core section includes a plurality of first fluid passages through which a first fluid is flowed, and a plurality of second fluid passages through which a second fluid is flowed to exchange thermal energy with the first fluid. The first fluid passages and the second fluid passages extend non-linearly along a length of the first fluid passages and the second fluid passages between a first core end and a second core end opposite the first core end. A manifold is operably connected to the plurality of first fluid passages. The manifold includes a plurality of lateral passages intersecting the plurality of first fluid passages. The plurality of lateral passages vary in length depending on distance from a fluidly upstream end of the core section.

A heat exchanger includes heat transfer tubes disposed in an up-down direction and a distributor distributes refrigerant to the heat transfer tubes. The distributor has a main body having a first flow passage through which refrigerant flows upward, and an insertion part disposed inside the main body. When an upper one and a lower one of two among the heat transfer tubes are a first heat transfer tube and a second heat transfer tube, respectively, the insertion part is installed between the first heat transfer tube and the second heat transfer tube. The main body has a second flow passage through which refrigerant flows upward. Refrigerant having passed through the first flow passage and the second flow passage flows through the first heat transfer tube, and refrigerant having passed through the first flow passage flows through the second heat transfer tube.

A heat exchanger (HEX) for cooling air in a gas turbine engine is provided. An adjustable damper is provided. The adjustable damper may be for damping a movement of the HEX relative to the gas turbine engine. An adjustable damper may comprise: a first tube; a second tube located at least partially within the first tube; a housing coupled to the second tube; a moveable member, the moveable member comprising a contacting surface in contact with the second tube; an adjusting member adjustably coupled to the housing; and a spring member located between the moveable member and the adjusting member, the spring member configured to at least one of compress or decompress in response to adjusting member moving relative to the housing.

A heat exchanger includes a plurality of flat heat transfer tubes and a header, wherein, in an interior portion of each of the plurality of flat heat transfer tubes, a plurality of upwind side channels and a plurality of downwind side channels are formed, the header includes a main body portion in which an interior portion space connected to the plurality of upwind side channels and the plurality of downwind side channels is formed, a partition member that divides the interior portion space into an upwind side space, and a flow inlet/outlet port that supplies a refrigerant to a lower part of the upwind side space, and, at a lower part of the partition member, a lower communication path that communicates the downwind side space and the upwind side space is formed.
