PURPOSE:To enable effective prevention of frosting by a method wherein the ratio between the width in the direction of draft of the part of a radiator fin provided with a heat exchanger pipe and the overall width in the direction of draft of the radiator fin is set in a specified range. CONSTITUTION:A plurality of heat exchanger pipes 1 are stacked in a plurality of layers in the same direction in a state of being parallel to the direction (a) of draft by a strip-plate-shaped radiator fin 5 being long in the direction of height. The ratio between the overall width W2 of this radiator fin 5 and the width of the part of the radiator fin 5 provided with the heat exchanger pipe 1 is set to be W2/W1=1.2 to 1.9. Since the windward-side end part 5a is continuous in the vertical direction according to this constitution, a drain condensing on the surface of the radiator fin 5 is discharged easily onto the lower side of the radiator fin 5 through this end part before frosting on this part. Therefore the frosting can be prevented effectively and the capacity of heat exchange can be maintained excellently.
