Heat exchanger

A heat exchanger configured to exchange heat between a heat medium and an air, the heat exchanger comprising:

• a plurality of tubes arranged in an up-down direction, through which the heat medium passes;
• and
• a reinforcing plate arranged on a lower side of a lowermost tube of the plurality of tubes, wherein
• the reinforcing plate has a bent portion protruding downward and extending along a longitudinal direction of the plurality of tubes,
• the bent portion includes at least one discharge hole to discharge a condensed water flowing from an upper side toward a lower side,
• the bent portion has a lower end to define an upstream region upstream of the lower end in a flow direction of air and a downstream region downstream of the lower end in the flow direction of air,
• the discharge hole is formed by an upstream rib extending from the upper side toward the discharge hole in the upstream region and a downstream rib extending from the upper side toward the discharge hole in the downstream region, wherein a height dimension of the upstream rib is different from a height dimension of the downstream rib partially at least along the longitudinal direction of the plurality of tubes, and
• the height dimension of the upstream rib forming the one discharge hole is larger than the height dimension of the downstream rib forming the one discharge hole partially at least along the longitudinal direction of the plurality of tubes.
