Abstract
A heat exchanger configured to be positioned in a tail cone section of a fuselage of an aircraft and including a liner through which passes hot gases from an auxiliary power unit (APU) and plates within the liner, wherein the plates are hollow and receive a second fluid from a first collector and discharge the second fluid from the plates to a second collector.
Claims20
A heat exchanger for an aircraft, the heat exchanger arranged along a longitudinal direction and comprising:
- at least one plate having a first end and a second end opposite to the first end along the longitudinal direction, wherein the at least one plate comprises an inner hollow volume configured to house a second fluid to transfer heat from a first fluid located outside the at least one plate to the second fluid in the at least one plate,
- a first collector and a second collector configured to respectively output the second fluid off the at least one plate and input the second fluid into the at least one plate, wherein the first collector is located at the first end of the at least one plate and the second collector is located at the second end of the at least one plate,
- the first collector comprises at least one fluid outlet and the second collector comprises at least one fluid inlet, wherein the first collector and the second collector are configured to be in fluidic communication with the inner hollow volume of the at least one plate, the at least one fluid outlet and the at least one fluid inlet,
- at least one first sub-collector configured to connect the first collector to the first end of the at least one plate,
- at least one second sub-collector configured for connecting the second collector to the second end of the at least one plate, and
- a liner extending along a length according to the longitudinal direction, the liner configured to define an inner chamber confining the at least one plate, the first collector, the second collector, the first sub-collector and the second sub-collector,
- wherein the at least one plate comprises at least two sheets defining a fluid tight inner chamber, said sheets being coupled to each other by discrete spot welds joining respective portions of each sheet and, across their corresponding contours by means of a continuous weld.
A heat exchanger configured to be positioned in a tail cone section of a fuselage of an aircraft, the heat exchanger comprising:
- a liner including a hot gas inlet, a hot gas outlet and a hot gas passage between the hot gas inlet and outlet, wherein the hot gas inlet is configured to receive hot exhaust gas from an auxiliary power unit in the tail cone section;
- plates in the liner, wherein each of the plates includes a hollow volume within the plate, a closed first end facing the hot gas outlet and a closed second end facing the hot gas inlet, wherein the plates are arranged in the hot gas passage such that hot gases from the auxiliary power unit flow over surfaces of the plates as the hot gases flow through the hot gas passage;
- a first collector proximate the first ends of the plates and extending around at least a plurality of the plates, wherein the first collector includes a fluid passage in fluid communication with the hollow volumes of the plates and an inlet for a second fluid;
- a second collector proximate the second ends of the plates and extending around at least a plurality of the plates, wherein the second collector includes an internal fluid passage in fluid communication with the hollow volumes of the plates and an outlet for a second fluid;
- first sub-collectors each connected to the first collector and the plates, and forming fluid passages between the plates and the first collector, and
- second sub-collectors each connected to the second collector and the plates, and forming fluid passages between the plates and the second collector.
