An integrated heat exchanger comprises a primary heat transfer zone and a secondary heat transfer zone integral to the primary heat transfer zone. The primary heat transfer zone comprises an ECS heat exchanger and the secondary heat transfer zone comprises a heat exchanger for a secondary system, such as an OBIGGS heat exchanger. The integrated heat exchanger reduces the negative impact that the OBIGGS heat exchanger has on the ECS heat exchanger by providing one ram face, thereby minimizing the flow disturbances associated with the OBIGGS heat exchanger. By integrating the OBIGGS and the ECS heat exchanger, the integrated heat exchanger reduces the negative impact of the pressure drop and heat load caused by the OBIGGS heat exchanger.

Integrated heat exchangers for ECS and OBIGGS applications

The present invention provides a system and method for generation of nitrogen enriched air for inerting aircraft fuels tanks. One embodiment of the present invention includes a duct assembly; a primary heat exchanger; a gas generating system heat exchanger; a first temperature sensor; a second temperature sensor; a controller monitor; a valve; an air separation module assembly having a primary module and a secondary module; at least one flow control orifice; and a pressure sensor. The present invention utilizes a minimal complement of components and streamlined processes, thus minimizing structural and operational costs while optimizing performance and safety features.
