Abstract
A heat exchanger is configured such that flat tubes in at least two levels bent or connected to each other at one end in an axial direction of the flat tubes and the flat tubes in at least two columns connected to each other are included in refrigerant passages through which refrigerant flows, and a flow direction of gas is counter to flow of refrigerant through the refrigerant passages in a column direction while the heat exchanger serves as a condenser.
