To prevent outflow of a liquid coolant when the liquid level in the gas-liquid separator 20 is raised and outflow of a gas coolant when the liquid level is lowered, and to prevent increase in cost due to complicatedness of structure of the gas-liquid separator 20 in the gas-liquid separator 20 including: a gas-liquid separating container 21 for separating a coolant into gas and liquid; a two-phase coolant inlet pipe 22 connected to a side plate of the gas-liquid separating contaienr 21; a gas coolant outlet pipe 23 connected to an upper plate of the gas-liquid separating container 21; and a liquid coolant outlet pipe 24 connected to the base plate of the gas-liquid separating container 21.
The gas-liquid separator includes an auxiliary container 25, which is disposed so that the base is located in a position of predetermined height between the top plate and the base plate of the gas-liquid separating container 21, wherein the auxiliary container 25 is communicated with the gas-liquid separating container 21.
