PROBLEM TO BE SOLVED: To suppress occurrence of deviation in distribution of a first heat exchange medium by heat exchange tubes arranged on an upstream side of a second heat exchange medium and heat exchange tubes arranged on a downstream side of the second heat exchange medium.SOLUTION: A heat exchanger includes: a plurality of pieces of tubes 11 for exchanging heat between a first heat exchange medium flowing inside and a second heat exchange medium flowing outside; and a distribution header 13 for distributing the first heat exchange medium to the plurality of pieces of tubes 11. The plurality of pieces of tubes 11 are arranged so as to form upstream rows 11A located on the flow direction upstream side of the second heat exchange medium and downstream rows 11B located on the flow direction downstream side of the second heat exchange medium, and the number of tubes 11 forming the upstream rows 11A is larger than the number of tubes 11 forming the downstream rows 11B.SELECTED DRAWING: Figure 3 |
