Abstract: A cooling device is provided, which comprises a cooling circuit comprising an evaporator and a compressor connected to the evaporator by a first fluid line of the cooling circuit, wherein the compressor is adapted to compress cooling agent in the cooling circuit during an active cooling mode, wherein the compressed cooling agent contains lubricant oil from the compressor. The cooling circuit comprises a condenser, which is connected to the compressor by a second fluid line of the cooling circuit. The second fluid line is connected to a fluid by-pass line of the cooling circuit by a separating portion, and wherein the separating portion is adapted to physically separate lubricant oil from the compressed cooling agent, so that the lubricant oil is collected in the fluid by-pass line.
