Cooling apparatus

A cooling apparatus for electric equipment, the apparatus comprising:

• a closed compartment;
• first and second electric components arranged inside of the closed compartment, an operating temperature of the second electric components being lower than an operating temperature of the first electric components;
• an absorber arranged outside of the closed compartment, the absorber being configured to receive heated fluids from within the closed compartment, and transfer heat from the heated fluid to the outside of the closed compartment;
• a condenser arranged outside of the closed compartment, the condenser being configured to receive heated fluid from within the closed compartment and transfer heat from the heated fluid to the outside of the closed compartment;
• a generator arranged in the closed compartment, the generator comprising a fluid channel configured to receive a first fluid and a second fluid in a liquid state, the first and the second fluids being miscible, to heat the received liquids with heat received from the first electric components, to provide the condenser with the vaporized second fluid in a gas state, and to provide the absorber with the first fluid in a liquid state;
• a first expansion device configured to receive the second fluid from the condenser in a liquid state at a first pressure, reduce the first pressure of the second fluid, and forward the second fluid in a liquid state and with a third pressure which is lower than the first pressure;
• an evaporator arranged in the closed compartment, the evaporator comprising a fluid channel configured to receive the second fluid from the first expansion device in a liquid state, to evaporate the second fluid with heat received from the second electric components, and to forward the evaporated second fluid in a gas state to the absorber;
• a second expansion device configured to forward the first fluid in a liquid state from the generator to the absorber, to receive the first fluid at a second pressure, to reduce the pressure of the first fluid, and to forward to the absorber the first fluid with a fourth pressure which is lower than the second pressure,
• wherein the absorber is configured to receive the first fluid in a liquid state from the generator, the second fluid being in a vaporized gas state from the evaporator, to absorb the vaporized second fluid by the first fluid in a liquid state to obtain a liquid of the miscible first and second fluids while transferring heat from the fluids to the outside of the closed compartment, and to provide the generator with the first and second fluids in a liquid state, and
• wherein the apparatus comprises a pump configured to increase for increasing a pressure of the first and second fluids provided by the absorber to the generator.
