PROBLEM TO BE SOLVED: To suppress the uneven flowing-down of warm water to a heat exchanging unit, and to suppress the deterioration of cooling performance.SOLUTION: A cooling tower is equipped with a warm water supply device, a warm water tank 3, a heat exchanging unit 4. The warm water tank 3 has a collecting portion 30, a plurality of sprinkle holes 31, and a plurality of water level adjusting portions 32. The plurality of sprinkle holes 31 are distributed on a bottom portion 301 of the collecting portion 30 at intervals in a first direction and a second direction orthogonal to the first direction in a plane view. The water level adjusting portions 32 project upward from the bottom portion 301, and are partially lower than the height of a collecting space. The water level adjusting portion 32 has a wall portion 321 for forming an inner space closed in the plane view. The plurality of sprinkle holes 31 has first sprinkle holes 311 and second sprinkle holes 312. The first sprinkle holes 311 are positioned on the inner side of the water level adjusting portion 32 in the plane view, and the second sprinkle holes 312 are positioned on the outer side of the plurality of water level adjusting portion 32. The collecting portion 30 has a first area 100 in which only the second sprinkle holes 312 are aligned in the second direction over the whole length in the second direction of the bottom portion 301, and warm water from the warm water supply device 2 is supplied. |
