In the case of the sheet-type filler module 300a, the contact area is increased compared to that of the mesh type, thereby improving heat exchange efficiency. However, when the supply water is sprayed from the nozzle 210, there is a problem that the possibility of damage is also increased because the amount of impact is larger than that of the mesh type.

Therefore, by forming the filler module 300a according to the embodiment of a metal material, such a problem can be solved.

Further, the filler module 300a according to the embodiment is formed in an assembly type in which a plurality of plates are detachably assembled, so that even if some of the plates of the filler module 300a are damaged, only the damaged plate can be replaced. .

In addition, as shown in FIG. 3, the filler modules 300a stacked in the vertical direction form the flow of the supply water in a zigzag shape, thereby improving the contact amount between the supply water and the air.

Here, the plurality of holes 322 may be disposed to be spaced apart from each other at a predetermined interval. At this time, the hole 322 may be formed in a predetermined size so that only the supply water can pass.

9 and 10, as the plurality of holes 322 are disposed to be spaced apart from each other at a predetermined interval, the supply water flowing along the swash plate 320 diverges and flows to bypass the hole 322. I can. Accordingly, the contact amount between the swash plate 320 and the feed water may be improved. In this case, a part of the supply water flowing along the swash plate 320 may be sprayed through the hole 322 as described above.
