Abstract
A heat exchanger to cool an oil flow with an air flow and a fuel flow includes at least one oil flow layer to receive the oil flow, an air flow layer to receive the air flow, wherein the air flow layer is in thermal communication with the at least one oil flow layer, and a fuel flow layer to receive the fuel flow, wherein the fuel flow layer is in thermal communication with the at least one oil flow layer.
Claims15
A heat exchanger to cool an oil flow with an air flow and a fuel flow, the heat exchanger comprising:
- at least one oil flow layer to receive the oil flow, the at least one oil flow layer including an air cooled oil flow layer and a fuel cooled oil flow layer,
- the air cooled oil flow layer being disposed adjacent to an air flow layer and the fuel cooled oil flow layer being disposed adjacent to a fuel flow layer, and
- the air cooled oil flow layer and the fuel cooled oil flow layer are adjacent to one another in an oil layer to oil layer interface, wherein:
- the air flow layer is configured to receive the air flow, wherein the air flow layer is in thermal communication with the air cooled oil flow layer of the at least one oil flow layer;
- and
- the fuel flow layer is configured to receive the fuel flow, wherein the fuel flow layer is in thermal communication with the fuel cooled oil flow layer of the at least one oil flow layer,
- wherein patterns of oil flows through the air and fuel cooled oil flow layers are the same along entire lengths of each of the air and fuel cooled oil flow layers.

An oil cooling system, comprising:
- an engine nacelle comprising an engine core cowl interface;
- and
- a heat exchanger disposed at the engine core cowl interface, the heat exchanger comprising an air cooled oil cooler and a fuel cooled oil cooler in a single unit comprising:
- an oil flow layer receptive of an oil flow and comprising an air cooled oil flow layer and a fuel cooled oil flow layer,
- the air cooled oil flow layer being adjacent to an air flow layer, the fuel cooled oil flow layer being disposed adjacent to a fuel flow layer and the air cooled oil flow layer and the fuel cooled oil flow layer are disposed adjacent to one another in an oil layer to oil layer interface, wherein:
- the air flow layer is receptive of an air flow from a fan air flow within the engine nacelle and is thermally communicative with the air cooled oil flow layer;
- and
- the fuel flow layer is receptive of a fuel flow and is thermally communicative with the fuel cooled oil flow layer,
- wherein patterns of oil flows through the air and fuel cooled oil flow layers are the same along entire lengths of each of the air and fuel cooled oil flow layers.
