Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2013/150795
Kind Code:
A1
Abstract:
A heat exchanger wherein the ends of flat pipes (31) are inserted into a header collecting pipe (70). When the heat exchanger functions as an evaporator, a refrigerant in a gas-liquid two-phase state flows upward in a partial space (71a) in the header collecting pipe (70). The effective cross-sectional area A of the partial space (71a) of the header collecting pipe (70) is set on the basis of the mass flow rate of the refrigerant flowing to the partial space (71a) in the header collecting pipe (70). This effective cross-sectional area A is the area when the projected area A1, which is the area (projected on the plane orthogonal to the axial direction of the header collecting pipe (70)) of the portion of a flat pipe (31) positioned in the partial space (71a), is subtracted from the area A0 of the cross section of the partial space (71a) orthogonal to the axial direction of the header colleting pipe (70).
