PROBLEM TO BE SOLVED: To perform the stable heat exchange of air by circulating a heat exchange medium more evenly, and to suppress the generation of noise when the heat exchange medium circulates in a heat exchanger.SOLUTION: In a first tank 12 constituting a heat exchanger 10, a branching plate 26 is provided in a space 24 which extends from one end 12a of the first tank 12 with a guide-in pipe 20 connected thereto to the other end 12b thereof so as to divide the space 24. The branching plate 26 is disposed below so that one end which is the guide-in pipe 20 side is at a tube 16 side connected to the space 24. On the other hand, the other end is provided to be inclined at a predetermined angle so as to be separated from and above the tube 16. At the branching plate 26, a plurality of holes 32a-32e are formed to be separated from one another with constant intervals along a length direction. Among diameters of the holes 32a-32e, the diameter of the hole at one end of the branching plate 26 is the smallest and the diameters of the other holes are increased stepwise toward the other end of the branching plate 26. |
