Abstract: A heat exchange system for an aircraft engine includes a heat exchanger, a main conduit directing fuel to a combustion chamber of the aircraft engine, and a pump connected to the main conduit. A return conduit receives excess fuel outputted by the pump and exceeding a fuel requirement of the combustion chamber. The return conduit, which is connected to a fuel conduit of the heat exchanger, has an inlet connected to the main conduit downstream of the pump and an outlet connected to the main conduit upstream of the pump. An actuator has an inlet connected to the main conduit downstream of the pump and an outlet connected to the main conduit upstream of the pump while bypassing the heat exchanger, wherein a pressure differential between the actuator inlet and the actuator outlet remains substantially unchanged with variations of a fuel flow through the heat exchanger.

Abstract: The heat exchanger system can have a first conduit extending from at least one first conduit inlet through a heat exchanger to at least two first conduit outlets; a second conduit extending from at least one second inlet through the heat exchanger to at least one second outlet, the first and second conduits disposed adjacent to one another in heat exchange engagement within the heat exchanger; and a bypass conduit extending from the first conduit between the at least one first inlet and the heat exchanger to the first conduit between the heat exchanger and at least one of said at least two first outlets.
