Abstract
An outdoor heat exchanger includes a plurality of fins, a blower mechanism, a plurality of heat transfer pipes arranged side by side in a vertical direction, and a first flow divider connected to the plurality of heat transfer pipes. The plurality of heat transfer pipes includes a lowermost heat transfer pipe located on a lowermost side and at least one upper heat transfer pipe located above the lowermost heat transfer pipe. The upper heat transfer pipe includes a merging path connected to the first flow divider, a second flow divider provided at an end portion of the merging path, and at least two branch paths branched from the second flow divider, a flow resistance of a refrigerant in a liquid phase inside the upper heat transfer pipe is smaller than a flow resistance of the refrigerant in a liquid phase inside the lowermost heat transfer pipe.
