Abstract
A heat exchanger includes: flat tubes; a plate attached to the flat tubes; a medium tank configured to form a medium flow path by covering openings of flat tubes; and a reinforcing member to reinforce the openings. The reinforcing member includes a pair of leg portions and a connection portion that connects the leg portions. An insertion amount of the leg portions into the opening is larger than a sum of a gap between the connection portion and an inner surface and a length from the opening to a position corresponding to a brazed portion between the flat tube and the plate, or when a protruding portion protruding in a direction opposite an insertion direction is provided in the connection portion, larger than a sum of a gap between the protruding portion and the inner surface and a length from the opening to the position corresponding to the brazed portion.
