<p>PROBLEM TO BE SOLVED: To inhibit the flow of a non-uniform mass flow rate of refrigerant in a plurality of flat tubes constituting two tube arrays.SOLUTION: A heat exchanger (23) includes: an upwind tube array (50) and a downwind tube array (90) constituted of a plurality of flat tubes (31, 61) arrayed in parallel, respectively, and laid side by side in the flowing direction of air; fins (32, 62) jointed to the flat tubes (31, 61); and a connection unit (100). The connection unit (100) has n-pieces of communication passages for communicating the ends of the n-pieces of flat tubes (31) constituting the upwind tube array (50) with the ends of the n-pieces of flat tubes (61) constituting the downwind tube array (90) on a one-to-one basis.</p> |
