ABSTRACT:
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.
