1. An apparatus comprising:
a generator, an evaporator, an absorber and a condenser circulating a refrigerant, an inert and an absorbent in a diffusion-absorption cycle, wherein
the generator and the evaporator are arranged in an electric cabinet separating the generator and evaporator from the surrounding environment, the generator is arranged to receive a heat load from primary electric components in the electric cabinet and to pass the heat load into fluid in the generator for evaporating at least a part of the fluid with the heat load from the primary electric components, the evaporator is arranged to receive a heat load from secondary electric components in the electric cabinet which have a lower operating temperature than the primary electric components and to pass the heat load into fluid in the evaporator for evaporating at least a part of the fluid with the heat load from the secondary electric components, the absorber and the condenser are arranged outside of the electric cabinet and at a higher level than the evaporator to receive fluid from the generator and the evaporator and for dissipating heat from the received fluid to the surrounding environment, and the inert is heavier than the refrigerant whereby the inert exiting the absorber flows downwards to the evaporator and the inert exiting the evaporator flows upwards to the absorber. |
