  • HEAT EXCHANGER, AIR-CONDITIONING APPARATUS EQUIPPED WITH HEAT EXCHANGER, AND METHOD FOR PRODUCING HEAT EXCHANGER
    Publication number: 20190346208
    Abstract: A heat exchanger includes plural heat exchanger cores, each of which includes plural tabular fins with notches formed therein and plural heat transfer tubes. The plural fins are disposed such that planes of the fins face each other. The plural heat transfer tubes are hairpin tubes each of which is bent in a U-shape. The hairpin tubes are placed in the notches in the fins so as to extend in a direction crossing the planes of the fins. The plural heat exchanger cores are placed side by side in a direction crossing the direction of the notches in the fins and at the same time a direction along the planes of the fins. A brazing sheet is disposed between adjacent ones of the heat exchanger cores. The adjacent ones of the heat exchanger cores are brazed together by the brazing sheet.
