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.
