PURPOSE:To make the flow of air constant and improve heat exchanging performance by a method wherein the arranging intervals of the heat dissipating fins of a heat exchanger, which are arranged near a part in which the speed of airflow ventilated from a ventilating impeller is high, are made close while the arranging intervals of the same fins, which are faced to a part in which a distance is apart from the ventilating impeller and the speed of airflow becomes low, are lengthend. CONSTITUTION:A heat exchanger 6, in which a multitude of plate type heat dissipating fins 5 are bonded on the outer surface of a refrigerant pipeline 4 through pressure bonding, is arranged so as to be opposed to the flow of air, which is generated by a ventilating device. The flow speed of air, generated by the ventilating device, is high normally when it is closer to a ventilating impeller 2, therefore, the arranging intervals of the plate type heat dissipating fins 5, neighbored to these parts, are formed close to mitigate the flow of passing air while the arranging intervals of the same fins 5 faces to the part apart from the ventilating impeller 2 are lengthened to reduce a resistance against the passing airflow.
