Abstract: In a heat exchanger, each of flat tubes (31) has an end portion inserted in a header-collecting pipe (70). When the heat exchanger functions as an evaporator, a refrigerant in a gas-liquid two-phase state upwardly flows in a subspace (71a) located in the header-collecting pipe (70). An effective cross-sectional area A of the subspace (71a) in the header-collecting pipe (70) is set based on a mass flow rate of the refrigerant flowing into the subspace (71a) in the header-collecting pipe (70). The effective cross-sectional area A is obtained by subtracting a projected area A1 which corresponds to a portion of each flat tube (31) located in the subspace (71a) and is projected onto a plane perpendicular to an axial direction of the header-collecting pipe (70) from an area A0 of a cross section of the subspace (71a) which is perpendicular to the axial direction of the header-collecting pipe (70).

Abstract: A heat exchanger includes a plurality of flat tubes and at least one wavily folded fin disposed between a pair of the flat tubes. The fin includes a heat transfer portion having a folded portion joined to a planar portion of each of the pair of flat tubes, and a cut-and-raised portion. The cut-and-raised portion is formed by raising a periphery of a cutting line segment when a material of the fin is wavily folded. The cutting line segment is set in a vicinity of a hypothetical center line of the folded portion before the material of the fin is wavily folded. The cutting line segment is formed by a combination of cutting line segments intersecting with the hypothetical center line, or a combination of a cutting line segment intersecting with the hypothetical center line and a cutting line segment displaced with respect to the hypothetical center line.
