Abstract

An accumulator arrangement suitable for use in a cooling system designed for operation with a two-phase refrigerating medium, includes an accumulator vessel with a receptacle for receiving a refrigerating medium. A liquefier of the accumulator arrangement is adapted to liquefy refrigerating medium to be received into the receptacle of the accumulator vessel before fed in the receptacle of the accumulator vessel and includes a refrigerating medium outlet for discharging refrigerating medium which liquefied in the liquefier from the liquefier. The accumulator arrangement includes a heat exchanger arranged in the receptacle of the accumulator vessel and a refrigerating medium inlet connected to the refrigerating medium outlet of the liquefier for feeding refrigerating medium liquefied in the liquefier into the heat exchanger, and a refrigerating medium outlet which opens into the receptacle of the accumulator vessel for discharging refrigerating medium from the heat exchanger into the receptacle of the accumulator vessel.
