USE OF A HEAT SOURCE FOR GENERATION OF ELECTRICITY AND AIRCRAFT COMPRISING A COOLING SYSTEM

A cooling system containing a two-phase refrigerant that comprises a condenser, an evaporator and a conveying device. The evaporator is integrated in a heat source or thermally coupled thereto. Gaseous refrigerant from the evaporator is expanded in an expander, converted into mechanical energy and used to drive a generator for generation of electricity. Furthermore, an aircraft comprising a cooling system, wherein an electrical drive is supplied with electricity from a fuel cell, cooled using the cooling system, and the generator of the cooling system.
