Title: HEAT EXCHANGER, AIR CONDITIONER PROVIDED WITH HEAT EXCHANGER, AND METHOD FOR MANUFACTURING HEAT EXCHANGER
Abstract:
A heat exchanger is provided with a plurality of heat exchanger cores each having: a plurality of flat plate fins in which notches are formed; and a plurality of heat transfer tubes. The plurality of fins are arranged so that planes thereof are opposed to each other. The plurality of heat transfer tubes are hairpin tubes bent into a U shape. The hairpin tubes are arranged in the notches of the fins so as to extend in a direction crossing the planes of the fins. The plurality of heat exchanger cores are arranged side by side in a direction which crosses the direction of the notches of the fins and is along the planes of the fins. A brazing sheet is disposed between the adjacent heat exchanger cores. The adjacent heat exchanger cores are brazed and joined to each other by the brazing sheet.
