Abstract (en)
There is provided a heat exchanger capable of suppressing a decrease in the amount of heat exchange due to the nonuniform air velocity distribution. The heat exchanger includes an inlet header (20), an outlet header (21), a plurality of rooms (31) partitioned by partition plates (30) inside the inlet header (20), a plurality of flat tubes (22) arranged in parallel and connected to each room (31) and the outlet header (21), a distributor (25) provided in a refrigerant pipe (10), and a plurality of branch pipes (24) connected to each room (31) and the distributor (25), in which depending on an air velocity distribution, the branch pipe (24) has a branch portion (27) provided between the room (31) and the distributor (25), and the number of the branch portions (27) of the branch pipe (24) connected to the room (31), to which the flat tubes (22) located in a part having a high air velocity are connected, is less than the number of the branch portions (27) of the branch pipe (24) connected to the room (31), to which the flat tubes (22) passing through a part having a low air velocity, are connected.
