PROBLEM TO BE SOLVED: To provide an evaporation type condenser capable of easily and efficiently removing a scale adhering to a heat transfer tube, a cooling device, and a scale removing method of the evaporation type condenser. SOLUTION: The evaporation type condenser 10 includes a casing 12, the heat transfer tube 20 which is provided in the casing 12, and in which a coolant circulating in a refrigeration cycle flows, a sprinkler nozzle 19 for spraying cooling water to the heat transfer pipe 20, a circulation pump 15 for circulating the cooling water stored at the lower part of the casing 20 and feeding the water to the sprinkler nozzle 19, an inlet closing valve 22A for stopping the inflow of the coolant into the heat transfer pipe 20, and an outlet closing valve 22B for stopping the discharge of the coolant from the heat transfer pipe. For removing the scale of the evaporation type condenser, the circulation of the coolant in the heat transfer pipe 20 is stopped by the coolant inlet closing valve 22A and the coolant outlet closing valve 22B, and then, a decompression means 50 is used to decompress the inside of the heat transfer pipe 20.
