Claim 1:
2. The cooling device according to claim 1, wherein in the active cooling mode the compressor is adapted to compress gaseous cooling agent, wherein the compressed gaseous cooling agent is adapted to be conducted together with the lubricant oil through the first fluid line to the condensing unit, wherein the condensing unit is adapted to condensate the compressed gaseous cooling agent and to obtain liquid cooling agent, wherein the obtained liquid cooling agent is adapted to be conducted together with the lubricant oil through the second fluid line and through the expansion device to the evaporating unit, wherein the evaporating unit is adapted to at least partially evaporate the liquid cooling agent and to obtain a mixture of gaseous and liquid cooling agent, wherein the obtained mixture of gaseous and liquid cooling agent is adapted to be conducted together with the lubricant oil through the third fluid line to the additional evaporator, wherein the additional evaporator is adapted to completely evaporate the liquid cooling agent and to obtain gaseous cooling agent, wherein the obtained gaseous cooling agent is adapted to be conducted through the fourth fluid line back to the compressor.
