    • A finned heat exchanger includes a plurality of elongated fins which are arranged at a predetermined interval in parallel with one another such that air flows between neighboring ones of the fins in a predetermined direction. A plurality of heat transfer tubes which contain refrigerant passing therethrough are orthogonally inserted through the fins so as to be arranged in a plurality of columns on the fins. When the finned heat exchanger is operated for condensation, the heat transfer tubes are provided in two paths in the vicinity of an inlet for the refrigerant and are provided in one path in the vicinity of an outlet for the refrigerant, such that the heat transfer tubes of the one path occupy about 5 to 30% of all the heat transfer tubes.
    • 翅片式热交换器包括多个细长翅片,它们以预定的间隔彼此平行地布置,使得空气在预定方向上在相邻翅片之间流动。 包含通过其中的制冷剂的多个传热管通过翅片正交地插入,以便布置在翅片上的多个列中。 当翅片式热交换器运行冷凝时,传热管在制冷剂入口附近的两条路径上设置,并且设置在用于制冷剂的出口附近的一个路径中,使得传热管 的一个路径占据所有传热管的约5至30%。
