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.
Claims12
A heat exchanger comprising:
- multiple fins, each fin being planar and each having a main planar face extending in a longitudinal direction;
- multiple heat transfer pipes joined to the fins and having an oval shape or a flat shape in cross-section;
- and
- a header connected, on one end side, to a cylindrical end portion of an inlet pipe, and the header is connected, on another end side, which is an opposite side to the end side, to respective end portions of each of the heat transfer pipes,
- wherein the header includes a longitudinal partition plate that is parallel to each main planar face of each of the multiple fins and is 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 respective end portions of each of the heat transfer pipes,
- wherein the end portion of the inlet pipe is spaced from the longitudinal partition plate, and
- wherein an opening is disposed in the longitudinal partition plate and a projection of the axis of the cylindrical end portion of the inlet pipe does not intersect with the opening.
