Abstract
In a corrugated fin unit assembled to a serpentine-anfractuous refrigerant pipe in a serpentine-type heat exchanger, each of generally parallel fin plate portions of the fin unit has a group of louvers parallel to the fin plate portion in the windward region and another group of louvers inclined downwardly in the leeward region, to thereby reduce air flow resistance of each fin unit without substantial reduction of heat exchange rate of the heat exchanger.
