PROBLEM TO BE SOLVED: To provide a cooling system having high cooling efficiency and high reliability by connecting a steam compression type refrigerant circuit to a gravity type thermosyphon refrigerant circuit using a gravity as a drive force through intermediate heat exchangers. SOLUTION: This cooling system comprises two refrigerant circuits having a steam compression type refrigerant circuit formed of at least a compressor 1, a condenser 2, restrictors 4a and 4b, and evaporators 21a and 22a and a gravity type thermosyphon refrigerant circuit formed of at least a heat absorbing side heat exchanger and a heat radiating side heat exchanger and driven with no power. These two refrigerant circuits are connected to each other through the intermediate heat exchangers 5a and 5b so that the evaporation side of the steam compression type refrigerant circuit can exchange heat with the heat radiation side of the gravity type thermosyphon refrigerant circuit.
