Abstract
A heat exchanger includes: a plurality of tubes arranged in an up-down direction; and a reinforcing plate arranged on a lower side of a lowermost tube of the plurality of tubes. The reinforcing plate has a bent portion protruding downward and extending along a longitudinal direction of the tube. The bent portion includes at least one discharge hole to discharge a condensed water. The discharge hole is formed by an upstream rib extending from the upper side toward the discharge hole in an upstream region and a downstream rib extending from the upper side toward the discharge hole in a downstream region, and a height dimension of the upstream rib is different from a height dimension of the downstream rib at least partially along a longitudinal direction of the tube.
