Abstract: PURPOSE:To prevent water from scattering into a room by a method wherein a mesh fin is attached at the leeward end of a corrugated fin so that condensate water gathering on the corrugated fin is absorbed by the mesh fin. CONSTITUTION:Refrigerant evaporates in a flat pipe 21 to cool air passing through a corrugated fin 22, and moisture condenses on the corrugated fin 22. The condensate water is washed away backward from the corrugated fin 22 by air flow and absorbed by a mesh fin 23 attached at the leeward end of the corrugated fin 22. Then, the condensate water flows along the mesh fin 23 and is discharged outside without scattering into a room. Therefore, the draft resistance can be reduced.
