Abstract
In a heat exchanger, a plate member of a tank portion includes a first fluid communication passage through which a first tank space communicates with first tubes, and a second fluid communication passage through which a second tank space communicates with second tubes. Either an upstream first tube group of the first tubes or a downstream first tube group of the first tubes, whichever is larger in a pressure loss of the first fluid, configures a higher pressure loss first tube group, and the other first tube group smaller in the pressure loss of the first fluid configures a lower pressure loss first tube group. A flow channel resistance between the higher pressure loss first tube group and the first tank space is smaller than a flow channel resistance between the lower pressure loss first tube group and the first tank space.
