Abstract:
A heat exchanger assembly for an aircraft includes a first heat exchanger with a first hot air circuit, a second heat exchanger with a second hot air circuit, a third heat exchanger with a third hot air circuit, and a cold circuit. The first heat exchanger is in fluid communication with a source of bleed air from the engine. The second heat exchanger is disposed adjacent to and in fluid communication with the first heat exchanger. The third heat exchanger is disposed adjacent to and in fluid communication with the second heat exchanger. The first, second, and third heat exchangers are fluidly connected in series. The cold air circuit passes through each of the first, second, and third heat exchangers. The first, second, and third heat exchangers are in cross-flow communication with the cold air circuit.

Claim (Index 11):
A method of transferring thermal energy in an environmental control system, the method comprising:\n passing hot air of a first hot air circuit through hot layers of a first heat exchanger of the environmental control system; passing hot air of a second hot air circuit through hot layers of a second heat exchanger of the environmental control system; passing hot air of a third hot air circuit through hot layers of a third heat exchanger of the environmental control system, wherein the first, second, and third heat exchangers are fluidly connected in series, and wherein the first, second, and third heat exchangers are brazed together to form a single unitized tri-heat exchanger; and passing cold air of a cold air circuit through cold layers of each of the first, second, and third heat exchangers, wherein a direction of flow of the cold air circuit is perpendicular to directions of flow of the first, second, and third hot air circuits.
