Cooling apparatus

A cooling apparatus for electric equipment comprising:

• an evaporator configured to receive a second heat load from second electric components, the evaporator comprising a second fluid channel configured to transfer heat received from the second electric components into the second fluid channel, the second fluid channel of the evaporator being configured to receive a fluid in a liquid state and a fluid in a gas state, the fluid in the gas state reducing a partial pressure of the fluid in the liquid state and a temperature required for evaporating the fluid in the liquid state, such that the fluid in the liquid state is evaporated;
• a closed compartment enclosing the evaporator and the second electric components;
• a generator configured to receive a first heat load from first electric components having a higher operating temperature than the second electric components, the generator comprising a first fluid channel configured to receive liquid and to evaporate a part of the received liquid with the first heat load from the first electric components, the generator and the first electric components being enclosed in the closed compartment;
• and
• a third cooling element arranged outside of the closed compartment and configured to receive heated fluid from at least one of the generator and the evaporator, and to transfer heat from the heated fluid to outside of the closed compartment.
