1. A cooling system containing a two-phase refrigerant, comprising:
a condenser which is configured to cool the two-phase refrigerant and to convert gaseous refrigerant into liquid refrigerant;
an evaporator which is integrated in a heat source or thermally coupled thereto and is configured to heat the two-phase refrigerant, wherein at least some of the refrigerant vaporizes to form gaseous refrigerant;
a conveying device which is configured to convey the two-phase refrigerant from the condenser to the evaporator;
a generator which is configured to generate electricity;
an expander which is fluidically connected to the evaporator downstream of the evaporator and is configured to expand the gaseous refrigerant from the evaporator, to obtain mechanical energy and to drive the generator;
a supply line which fluidically connects the conveying device to the evaporator; and
a regulating valve which is arranged in the supply line and is configured to regulate a flow rate of the refrigerant through the supply line; and,
a control system configured to control the regulating valve in such a way that the evaporator is operated in a wet vaporization process.
