Abstract

The present invention provides a heat exchanger capable of improving heat exchange efficiency. The heat exchanger, in which a plurality of flat plate-shaped fins 1a are stacked at predetermined intervals, heat exchanger tubes 2 for passing refrigerant therethrough are inserted in a stacking direction, air is caused to pass through between each fin group 1, and the heat exchanger tubes 2 are disposed in a plurality of rows in an air passage direction A, is characterized in that: the heat exchanger tube 2 is partitioned into a portion for containing gas and a high proportion of gaseous phase of a gas-liquid two-layer flow of the refrigerant flowing in said tube, and a portion for containing liquid and a high proportion of liquid phase of the gas-liquid two-layer flow of the refrigerant; first heat exchanger tubes 2a and 2b of a 2-pass structure are disposed as the former portion, and a second heat exchanger tube 2c of a 1-pass structure is disposed as the latter portion; these first and second heat exchanger tubes 2a, 2b and 2c are communicated to each other through a coupling member 3; each pass of these first and second heat exchanger tubes 2a, 2b and 2c has, when the heat exchanger is operated as a condenser, an inlet in a leeward-side row and an outlet in a windward-side row; and at least part of the passes are of a counterflow type, being overlapped between a plurality of rows in the air passage direction.
