Abstract
An electronics cooling system for an aircraft includes a heat exchanger comprising a coolant circuit, an air circuit, and a fuel circuit such that each of the circuits is in thermal communication with at least one of the other circuits. The coolant circuit is in thermal communication with one or more aircraft electronics. The air circuit is in fluid communication with at least one air source. The fuel circuit is in fluid communication with a fuel tank between the fuel tank and an engine of the aircraft.
Claims3
A method for cooling electronics on an aircraft, comprising:
- controlling at least one air valve disposed between at least one air source and a heat exchanger to be closed during ground operations, taxi, take off, and climb, and to be open during cruise, descent and landing;
- and
- controlling a fuel valve disposed between a fuel tank and the heat exchanger to be open during ground operations, taxi, take off, and climb, and to be closed during cruise, descent, and landing.
