[Problem] To provide a heat exchanger which allows a refrigerant to flow uniformly without using a complex structure even with a configuration in which the refrigerant circulates through upward core portions and downward core portions. [Solution] Predetermined formulae are established from the relationship among the number of tubes 20, the total flow cross-sectional area of the tubes 20, the length in the header axial direction of the refrigerant circulation space of a header 10, the maximum cross-sectional area in the header radial direction of the refrigerant circulation space 10a of the header 10, and the minimum cross-sectional area in the header radial direction of the refrigerant circulation space 10a of the header 10 in a single upward core portion or a single downward core portion.

[Problem] To provide a heat exchanger with which setting the optimum number of tube groups makes it possible to achieve better performance in a configuration having a header for each of a plurality of tube groups.

[Solution] A second control valve (350), which includes a spool (352) provided with a first valve part (352a) for opening and closing a pressure supply passage (145), and a second valve part (352b) for opening and closing a first pressure release passage (146b), is provided to the downstream side of a first control valve (300) for controlling the opening amount of the pressure supply passage (145). The spool (352) moves in accordance with the front-rear pressure difference. When the pressure (Pm) in the pressure supply passage (145) between the first control valve (300) and the second control valve (350) is higher than the pressure (Pc) in a crank chamber (140), the first valve part (352a) opens the pressure supply passage (145), and the second valve part (352b) closes the first pressure release passage (146b). When the pressure (Pm) is lower than the pressure (Pc), the first valve part (352a) closes the pressure supply passage (145), and the second valve part (352b) sets the opening amount of the first pressure release passage (146b) to the maximum opening amount.
