Abstract
A heat exchanger includes: a header; flat tubes disposed in line along a longitudinal direction of the header and connected to the header: a refrigerant pipe connected to an introduction space in the header; and a nozzle. When the heat exchanger operates as an evaporator of a refrigerant, the refrigerant is fed through the nozzle from the introduction space to a supply space disposed adjacent to the introduction space in the longitudinal direction of the header. The nozzle is disposed on a side closer to the flat tubes than to the refrigerant pipe. A width of a first zone in the introduction space on the side closer to the flat tubes is smaller than a width of a second zone in the introduction space on a side where the refrigerant pipe is connected.
