Embodiment Construction
[0027] figure 1 An exemplary embodiment of a motor vehicle 1 is shown with a cooling device for a battery module 2 . In addition to cooling by means of the conventional ventilation system 3 with blower 4 , the battery modules 2 can also be cooled with compressed air. In this case, valve 7 is opened by control unit 8 and compressed air is supplied from pressure accumulator 9 to battery module 2 . A throttle 10 is also provided between the pressure accumulator 9 and the battery module 2 . This restrictor restricts gas flow. As a result, gas expansion and thus cooling takes place in the subsequent line. The gas is fed to the battery module 2 at excess pressure, flows through it and is released again into the environment at the exhaust port 6 . The pressure accumulator 9 is part of the air spring system. The pressure accumulator is connected via a valve 12 to the pneumatics 13 of the air spring system. The pneumatic device 13 of the air spring system can supply compressed ai...
