1. A heat exchanger comprising:
heat transfer tubes aligned with one another;
a header connected to end portions of the heat transfer tubes; and
fins joined to the heat transfer tubes, wherein
when viewed in a longitudinal direction of the header, the header is divided into:
a circulation space comprising a first space in which refrigerant flows in a first direction along the longitudinal direction of the header and a second space in which the refrigerant flows in a second direction opposite to the first direction along the longitudinal direction, and
an insertion space into which the heat transfer tubes are inserted, the header comprises:
a circulation division plate that divides the first space from the second space; and
an insertion space forming plate that divides the circulation space from the insertion space, wherein
the insertion space forming plate forms a surface extending between the first space of the circulation space and the insertion space,
when viewed in the longitudinal direction of the header, the first space is between the circulation division plate and the insertion space forming plate,
the insertion space forming plate regulates a degree of insertion of the heat transfer tubes, and
in a direction perpendicular to an insertion direction of the heat transfer tubes when viewed in the longitudinal direction of the header, the insertion space forming plate is separated from portions of the header that constitute both ends of the first space in the direction perpendicular to the insertion direction.
