A system is provided for cooling a heat-dissipating device in a vehicle with a fuselage, a passenger cabin, and a region pneumatically communicating with the previously mentioned, which region is situated outside the passenger cabin. At least one heat exchanger is provided for transferring heat of the heat-dissipating device to air, and at least one air conveying device for conveying air through the heat exchanger. The air conveying device is designed to convey air from the passenger cabin to the heat exchanger. The heat exchanger is designed to subject the inflowing air to heat of the heat-dissipating device and to dissipate it to the region situated outside the passenger cabin, thus inducing mixing of the air that has been subjected to heat with the air present in the outside region, and inducing a return flow from the outside region to the passenger cabin by way of their pneumatic connection.

1. An aircraft, comprising: several air breathing engines;at least one electrical energy-requiring electrical device;at least one discharge valve configured to regulate airflow from the at least one passenger cabin to an environment external to the aircraft;at least one passenger cabin having a floor;a fuselage region situated outside the at least one passenger cabin and including a pneumatic connection connecting the fuselage region with the at least one passenger cabin;at least one heat-dissipating device in the form of a fuel cell disposed beneath the floor of the at least one passenger cabin in the fuselage region;at least one heat exchanger that subjects air to heat of the at least one heat-dissipating device and dissipates heat to the fuselage region, andat least one air conveying device configured to convey air from the at least one passenger cabin through the at least one heat exchanger,wherein mixing of the air subjected to heat from the at least one heat exchanger with air present in the fuselage region is induced in the fuselage region,wherein the pneumatic connection is at least one dado panel lining a cabin floor-to-wall transitionwherein the discharge valve is configured to close in the event of engine failure of the several air breathing engines and to cause the mixed air to flow from the fuselage region to the at least one passenger cabin; andwherein the fuel cell is used for generating electrical energy. 2. The vehicle of claim 1, wherein the at least one passenger cabin and the fuselage region are separated by a cabin floor. 3. The vehicle of claim 2, wherein the at least one heat exchanger is arranged on the cabin floor. 4. The vehicle of claim 1, wherein the at least one air conveying device is a recirculation blower. 5. The vehicle of claim 1, wherein the at least one heat-dissipating device is a fuel cell configured to provide electrical energy. 6. The vehicle of claim 1, wherein the vehicle is an aircraft. 7. The vehicle of claim 1, wherein the at least one heat exchanger is disposed beneath the floor of the at least one passenger cabin directly adjacent to the at least one heat-dissipating device. 8. A method for cooling a heat-dissipating device in a vehicle, the vehicle having several air-breathing engines, at least one electrical energy-requiring electrical device, and at least one discharge valve configured to regulate airflow from a passenger cabin of the vehicle to an environment external to the vehicle, the method comprising: dissipating heat from the heat-dissipating device to a heat exchanger disposed in a fuselage region of the vehicle separate from a passenger cabin of the vehicle;conveying air from the passenger cabin of the vehicle through the heat exchanger to the fuselage region situated outside the passenger cabin, the air conveyed through the heat exchanger mixing with the air in the fuselage region; andconcurrently inducing a flow of the mixed air from the fuselage region back to the passenger cabin from a pressure differential between the passenger cabin and the fuselage region, the flow of the mixed air induced with at least one dado panel arranged in the vehicle body and connecting the fuselage region to the at least one passenger cabin,wherein the discharge valve is configured to close in the event of a failure of the several air-breathing engines and to cause the mixed air to flow from the fuselage region to the passenger cabin;wherein and the fuel cell is used for generating electrical energy. 9. The method of claim 8, wherein the passenger cabin and the fuselage region are separated by a cabin floor. 10. The method of claim 9, wherein the heat exchanger is arranged on the cabin floor. 11. The method of claim 8, wherein the heat-dissipating device is a fuel cell configured to provide electrical energy. 12. An aircraft, comprising: several air breathing engines;at least one electrical energy-requiring electrical device;at least one discharge valve configured to regulate airflow from at least one passenger cabin to an environment external to the aircraft;a fuselage;at least one passenger cabin within the fuselage;a fuselage region situated outside the at least one passenger cabin and including a pneumatic connection connecting the fuselage region to the at least one passenger cabin;at least one heat-dissipating device in the form of a fuel cell disposed in the fuselage region;at least one heat exchanger that subjects inflowing air to heat of the at least one heat-dissipating device and dissipates heat to the fuselage region, andat least one air conveying device configured to convey air from the at least one passenger cabin through the at least one heat exchanger,wherein mixing of the air subjected to heat from the at least one heat exchanger with air present in the fuselage region is induced in the fuselage region,wherein the pneumatic connection is at least one dado panel lining a cabin floor-to-wall transitionwherein the discharge valve is configured to close in the event of failure of the several air-breathing engines and to cause the mixed air to flow from the fuselage region to the at least one passenger cabin; andwherein the fuel cell is used for generating electrical energy. 13. The aircraft of claim 12, wherein the at least one passenger cabin and the fuselage region are separated by a cabin floor. 14. The aircraft of claim 13, wherein the at least one heat exchanger is arranged on the cabin floor. 15. The aircraft of claim 12, wherein the at least one air conveying device is a recirculation blower. 16. The aircraft of claim 12, wherein the at least one heat-dissipating device is a fuel cell configured to provide electrical energy. 17. The aircraft of claim 12, wherein the at least one heat exchanger is disposed in the fuselage region directly adjacent to the at least one heat-dissipating device.
