Abstract:
Provided is a condenser (1) which has superior heat exchange performance and is suitable for an air-conditioning device dedicated for cooling operation. The condenser (1) comprises: a core (11) in which flat tubes (2) and fins (3) are alternately stacked; a first header (4) disposed at one end of the core (11); a second header (5) disposed at another end of the core (11); and a refrigerant supply pipe (6) and a refrigerant discharge pipe (7) which are connected to the first header (4).
