Abstract:
A heat exchanger including multiple fins, multiple heat transfer pipes having an oval shape or a flat shape and joined to the fins, and a header connected, on one end side, to an end portion of an inlet pipe through which working fluid flows in upon evaporation operation and connected, on the other end side, to an end portion of each of the heat transfer pipes, wherein the header includes a longitudinal partition plate arranged to extend in a longitudinal direction and configured to divide an internal space of the header into an inlet-pipe-side space connected to the end portion of the inlet pipe and a heat-transfer-pipe-side space connected to the end portion of each of the heat transfer pipes, and an opening is formed at a position not overlapping with the inlet pipe at the longitudinal partition plate.
