Abstract: PURPOSE:To prevent the ventilating amount of a heat exchanger as well as the generation of noise of the same by providing a thin film layer, having water absorbing property, on the lower end surface of a plate type fin. CONSTITUTION:The main body of a heat exchanger is constituted by a method wherein heat transfer tube penetrating holes are bored on a plate type fin 9 made of aluminum, on the lower end surface of which a resin layer 8 having water absorbing property is adhered to fix it, fin collars 2 are raised up around the holes bored with an equal interval to penetrate heat transfer tubes 3 made of copper and, thereafter, the tubes 3 are fixed so as to be contacted closely to the plate type fin 9 through the means of tube expanding and the like. Condensed water, which flows down to the lower end surface of the fin 9, is absorbed quickly by the water absorbing thin film layer 8 and the film of the condensed water on the surface of the fin 9 maintains the state of a thin water film. After the predetermined water absorbing capacity of the water absorbing resin film in attained, the water is extruded from the lower part of the water absorbing thin film layer 8 by an amount exceeding the predetermined water absorbing capacity and is dropped quickly. Accordingly, the condensed water on the fin 9 exists in the state of a thin water film at all times whereby the deterioration of the ventilating amount of the heat exchanger as well as the generation of noise of the same may be eliminated.
