Abstract
The invention relates to an apparatus () comprising a generator (), an evaporator (), an absorber () and a condenser () circulating a refrigerant (R), an inert (I) and an absorbent (A) in a diffusion-absorption cycle. The generator () and the evaporator () are arranged in an electric cabinet () to receive a heat load from primary electric components () and 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. The inert (I) and refrigerant (R) are selected such that the inert (I) is heavier than the refrigerant (R) in order to obtain fluid circulation where the inert (I) exiting the absorber () flows downwards to the evaporator () and the inert (I) exiting the evaporator () flows upwards to the absorber ().
