PROBLEM TO BE SOLVED: To provide a cooling device for a power generation source capable of detecting the shortage of a circulation amount of a cooling liquid without delay while lowering cost by eliminating a liquid level sensor.SOLUTION: A cooling device for a power generation source includes: a buffer tank 3 which stores a cooling liquid for cooling a power generation source comprising a gas engine generator 2 or a fuel cell; a cooling liquid circuit 4 which is arranged being in contact with the power generation source, which is formed by containing the buffer tank 3 and in which the cooling liquid flows; a circulation pump 5 which circulates the cooling liquid; a rotational speed sensor 55 which detects a rotation number N of the circulation pump 5; liquid temperature sensors 61 and 62 which detect temperatures T1 and T2 of the cooling liquid; and a monitoring control part 7 which monitors the rotation number N of the circulation pump and the temperatures T1 and T2 of the cooling liquid. The buffer tank 3 has a liquid outlet 31 from which the cooling liquid flows out to the cooling liquid circuit 4 at a liquid level position L2 of the time when the cooling liquid leaks to the limit of an allowable leakage amount. The monitoring control part 7 detects the shortage of a circulation amount of the cooling liquid on the basis of abnormality of at least one of the rotation number N of the circulation pump 5 and the temperatures T1 and T2 of the cooling liquid. |
