ABSTRACT:
An avionics cooling system including an avionics cooling circuit operating with a liquid coolant; a fuel circuit; and a vapor cooling cycle operating with a refrigerant. The avionics cooling circuit transfers heat withdrawn from avionics to the fuel circuit, whereby the heat is dumped into fuel, and the vapor cooling cycle transfers heat that cannot be dumped into the fuel from the fuel circuit to ram air.
