Abstract
A thermal management system avoids problems associated with the recirculation of fuel through a fuel tank on an aircraft in a system that includes a fuel reservoir ( ), a pump ( ) for pumping fuel from the reservoir ( ) to a first heat load ( ) and then to a check valve ( ) to a junction ( ). At least one second heat load ( ), ( ), ( ) is connected to the junction ( ) and a fuel/fan air heat exchanger ( ) having a fan air flow path in heat exchange relation with a fuel flow path having a fuel discharge end ( ) connected to the junction ( ). The fan air flow path is adapted to be connected to receive compressed air from the fan ( ) of an engine ( ). A bleed air/fuel heat exchanger ( ) receives fuel from the second heat load and bleed air from the engine ( ) and is connected to deliver fuel to the engine ( ). A control valve ( ) is interposed between the second heat load and the engine ( ) for proportioning the flow of fuel to the engine ( ) and the fuel fan heat exchanger ( ) so that excess fuel is recirculated without reintroduction into the fuel reservoir ( ).
