<p>PROBLEM TO BE SOLVED: To provide an outdoor heat exchanger for a heat pump-type refrigeration cycle capable of suppressing accumulation of a comparatively large amount of condensate between heat exchange tubes adjacent to each other in a heating operation, and being easily manufactured.SOLUTION: An outdoor heat exchanger 1 includes a plurality of tube-fin aggregates 2A, 2B composed of a plurality of flat heat exchange tubes 3 vertically disposed at intervals, and corrugated fins 4 respectively disposed between the adjacent heat exchange tubes 3 and arranged in the ventilating direction. The corrugated fins 4 of two tube-fin aggregates 2A, 2B adjacent in the ventilating direction are disposed on positions deviated in the vertical direction. Two corrugated fins 4 adjacent in the vertical direction of one of tube-fin aggregate 2B of two tube-fin aggregates 2A, 2B adjacent in the ventilating direction, and one corrugated fin 4 of the other tube-fin aggregate 2A positioned between two corrugated fins 4 are kept into contact with each other.</p> |
