PURPOSE:To produce formation of dew on the inlet side, by a method wherein, in a fin tube type cooler for an air conditioner and the like, a flange part, bent approximately at right angles with the flow of air, is formed to an end surface on the inlet side of the flow of air. CONSTITUTION:In a cooler 10, plural refrigerant pipes 12 are secured in a manner to extend through a number of plate fins 11, and an air flow is cooled through the medium of the plate fins 11 by means of a low temperature refrigerant flowing through the refrigerant pipe 12. Since a flange part 11', bent approximately at right angles with an air flow, shown by an arrow mark, is formed to the plate fin 11, a cut off area is formed on the inlet side of an air flow of the plate fin 11, to which eminent dew formation phenomenon occurs, formation of dew at 13 can be reduced, and dew is uniformly formed all the way through to the plate fin 11 on the outlet side of an air flow. This constitution ensures an air passage to prevent reduction of an airflow, and enables ensurance of cooling capability.
