Abstract
A heat exchanger includes heat transfer tubes disposed in an up-down direction and a distributor distributes refrigerant to the heat transfer tubes. The distributor has a main body having a first flow passage through which refrigerant flows upward, and an insertion part disposed inside the main body. When an upper one and a lower one of two among the heat transfer tubes are a first heat transfer tube and a second heat transfer tube, respectively, the insertion part is installed between the first heat transfer tube and the second heat transfer tube. The main body has a second flow passage through which refrigerant flows upward. Refrigerant having passed through the first flow passage and the second flow passage flows through the first heat transfer tube, and refrigerant having passed through the first flow passage flows through the second heat transfer tube.
