Abstract: A heat exchanger configured to cause a refrigerant to exchange heat with a heat medium, includes: plates stacked on top of one another. A first flow path and a second flow path are formed between the plates. The refrigerant in a two phase state flows through the first flow path and the heat medium flows through the second flow path. Each of the plates includes: a first inlet from which the refrigerant flows into the first flow path; and a first outlet from which the refrigerant flows out of the first flow path. In each of the plates, when viewed in a direction in which the plates are stacked, the first inlet has line symmetry with respect to a center line in a width direction of the each of the plates, and the first outlet has line symmetry with respect to the center line.

Abstract: A heat exchanger includes: a fin group including plate-shaped fins; heat transfer tubes penetrating the plate-shaped fins; and a support plate at an end of the fin group. The heat transfer tubes penetrate the support plate. The heat exchanger is configured to cause a heat medium flowing through the heat transfer tubes to exchange heat with air. End portions of the heat transfer tubes form protrusions protruding from the support plate. The protrusions include: a first protrusion connected to one of the protrusions adjacent to the first protrusion; and a second protrusion connected to a flow path pipe different from one of the protrusions adjacent to the second protrusion. A distance from a tip end of the second protrusion to the support plate is shorter than a distance from a tip end of the first protrusion to the support plate.
