Abstract (en)
A heat exchanger includes: a first heat transfer tube that has a flow passage through which refrigerant flows, the flow passage being located in the first heat transfer tube; a second heat transfer tube that has a flow passage through which refrigerant flows, the flow passage being located in the second heat transfer tube; and a header connected to an end of the first heat transfer tube in a tube axial direction and an end of the second heat transfer tube in the tube axial direction. The header includes a main body that allows refrigerant to flow between the first heat transfer tube and a refrigerant pipe through which refrigerant flows and between the second heat transfer tube and the refrigerant pipe, and an insertion portion shaped in a plate and that has a first opening. The first heat transfer tube and the second heat transfer tube are inserted in the first opening.
