Passive on-board aircraft cooling systems are provided with an evaporator/receiver in heat-exchange relationship with at least one heat source on board the aircraft, the evaporator/receiver containing a liquid phase working fluid which changes state to a vapor phase working fluid in response to heat transfer therefrom from the at least one heat source. First and second condensers are fluid-connected to the evaporator/receiver for receiving vapor phase working fluid from the evaporator/receiver. An aircraft-internal pressurized air supply stream is provided in heat-exchange relationship with the second condenser, and an aircraft-external unpressurized air supply stream is provided in heat-exchange relationship with the first condenser. At least a portion of the vapor phase working fluid transferred to the first and second condensers is thus condensed by heat transfer between the first and second condensers and the unpressurized and pressurized air supply streams, respectively, to thereby form liquid phase working fluid which returns to the evaporator/receiver by virtue of the fluid connection with the first and second condensers.
